Description:

CLAIM TO PRIORITY

Applicants hereby claim priority under all rights to which they are entitled under 35 U.S.C. Section 120 based upon the U.S. Provisional Application Ser. No. 60/606,917 for this patent application filed at the United States Patent and Trademark Office on Sep. 3, 2004.

FIELD OF THE INVENTION

The present invention relates to the field of seat cushion configurations. In particular, the present invention relates to a plurality of foam or fiber layers of different types, densities, and elasticities used to create a weight distribution and suspension system to obtain a longer lasting softness and more comfortable cushion for user body comfort.

BACKGROUND OF THE INVENTION

This invention pertains to a seat cushion apparatus that utilizes a weight distribution and suspension system to cushion the body of the user when he or she is seated on a hard surface for an extended period of time. It is not uncommon to be in attendance at an event where the only options for seating are hard and uncomfortable wood, metal, or concrete seats. After sitting on such a seating surface for even a short amount of time, the buttocks and lower back may become sore and uncomfortable because the cushion is either too firm or too soft such that it compresses completely to the hard surface below, leaving no support to the body of the user of the cushion. Such discomfort may make the cushion user unable to enjoy the event and may lead to more severe health concerns.

There exist in the background art stadium seat cushions. However, these inventions do not provide a cushion that is designed to distribute weight and retain its softness. Most bottom out (the effect of tail bone pressure against the hard surface below) within seconds due to the nature of the standard open cell foam having a minimum resistance to focused compression in a rather small surface area. These seats are usually no more than a means for applying a logo or advertisement. Other inventions take the standard flexible polyether urethane foam used in cushions and make it a little thicker to give more resistance to compression but the effect is short lived before the bottoming out is noticeable to the buttocks and the back of the user.

Existing patents focus mainly on new enclosures and covers, how such enclosures and covers are attached, and the accessories to cover a cushion. No art exists providing a technique or system to address a way to obtain a softer more comfortable cushion for an extended period of time. That is the purpose of this invention.

These and other problems exist. Previous attempts to solve these and other problems include the following.

Additionally, the present invention discloses a multi-layered weight suspensions system of five layers of alternating foam types.

While these patents and other previous methods have attempted to solve the above mentioned problems, none have utilized a plurality of alternating types, densities, and elasticities of material as does the present invention.

Therefore, a need exists for a weight distribution and suspension system for a human body in a seated position comprising a plurality of foam layers of alternating types, densities, and elasticities.

The foregoing patent and other information reflect the state of the art of which the inventor is aware and are tendered with a view toward discharging the inventor's acknowledged duty of candor in disclosing information that may be pertinent to the patentability of the present invention. It is respectfully stipulated, however, that the foregoing patent and other information do not teach or render obvious, singly or when considered in combination, the inventor's claimed invention.

BRIEF SUMMARY OF THE INVENTION

The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a multiple layered seating cushion. In particular, the present invention relates to a weight distribution and suspension system for a human body in a seated position comprising a plurality of foam layers of alternating types, densities, and elasticities.

The present invention is comprised of a plurality of foam layers of alternating types, densities, and elasticities which are incorporated into a stadium seat cushion and its cover with various features. The seat cushion and cover comprise a plurality of foam layers of alternating types, densities, and elasticities, a vinyl cushion cover, a second layer of vinyl, covering the top surface and creating a pocket; a fabric cushion backing; a mesh pocket for holding small items, comprised of a polyester elastic net mesh, within which to place items, pleats, and two elastic bands, a nylon zipper, a nylon hand strap, and two plastic rings to hold an optional shoulder carrying strap.

A primary advantage of the present invention is that the weight distribution and suspension system creates comfort to the human body seated on the cushion by displacing weight and downward force on the cushion over a plurality of foam layers of alternating densities and elasticities. This disbursement of body weight takes place not only over the top cushion surface, but also over the horizontal surfaces of each laminated foam layer. When weight is applied to the center area of the cushion, the compression is distributed below, thus creating greater comfort to the seated user.

Another advantage of the present invention is that the plurality of foam layers of alternating types, densities, and elasticities provides not only an initial softness to the user, but also provides retention of softness. Where other seat cushions will bottom out with use, this cushion allows for comfortable use over far greater periods of time.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

Before explaining the disclosed embodiment of the present invention in detail it is to be understood that the invention is not limited in its application to the details of the particular arrangement shown since the invention is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.

Referring now to FIG. 1, an isometric view of a seat cushion cover, the weight distribution and suspension system is shown in the embodiment of a seat cushion and seat cushion cover, 20, and displayed with its many features. Seat cushion cover, 20, is illustrated with a cover comprised of vinyl material, 22, and fabric covered cording, 26. The edges of seat cushion cover, 20, are finished and sewn using cording with fabric covered cording, 26. Seat cushion cover, 20, is illustrated with nylon strap handle, 32, sewn to the cover front, used for the purposes of easily carrying the seat cushion assembly by hand. Seat cushion cover, 20, is illustrated with plastic ring, 34, at each end to hold an optional shoulder carrying strap (not shown). Seat cushion cover, 20, is featured with multiple pockets: vinyl material pocket, 46, that can be used to hold a newspaper, program, or scorecard, among other things, and a pocket located on each end comprised of polyester elastic net mesh, 28, within which to place items, pleats, 44, and elastic bands, 42, to hold and contain items such as a cell phone, water bottle, or keys, among other things. Seat cushion cover, 20, is also illustrated with nylon zipper, 36, that is positioned on the back side and wraps around the two back corners to allow for inserting and removing the seat cushion, shown indirectly in FIG. 1.

Referring now to FIG. 2, an isometric view of a seat cushion, seat cushion, 10, as it appears without a cover placed over it, is shown. Reticulated filter foam, 14, is shown in alternating layers with another foam type, closed cell polyethylene, 12. Reticulated filter foam, 14, gives softness to the weight distribution and suspension system while the less elastic closed cell polyethylene, 12, prevents reticulated filter foam, 14, from compressing, to a state that is nearly or completely flat against the underlying surface, by displacing the downward force on seat cushion, 10, to the entire surface of seat cushion, 10. This layering of foam types, alternating closed cell polyethylene, 12, then reticulated filter foam, 14, then closed cell polyethylene, 12, then reticulated filter foam, 14, then closed cell polyethylene, 12, creates a torsion box effect in which the outside and center layers of foam, closed cell polyethylene, 12, are denser and less elastic than reticulated filter foam, 14. The torsion box effect can be easily understood by viewing a single layer of foam, such as closed cell polyethylene, 12, or reticulated filter foam, 14, in the same compression as the layered laminated foams of the weight distribution and suspension system. The torsion box effect is best achieved by laminating the varying densities of foam, closed cell polyethylene, 12 or reticulated filter foam, 14, to each other with adhesive, 16. By laminating the layers together on each side of the layer with adhesive, 16, horizontal and vertical movement of an individual layer is prevented. The laminating of the layers with adhesive, 16, may be accomplished by applying contact cement, or another type of glue, to each layer, melting the layers together, or thermally binding the layers together.

Referring now to FIG. 3, a top, planar view of a stadium seat, seat cushion cover, 20, is shown with vinyl material, 22, and cording with fabric covered cording, 26. Seat cushion cover, 20, is illustrated with nylon strap handle, 32, sewn to the cover front, used for the purposes of easily carrying the seat cushion assembly by hand. Additionally, seat cushion cover, 20, is illustrated with vinyl material pocket, 46, that can be used to hold a newspaper, program, or scorecard, among other things.

Referring now to FIG. 4, a front, planar view of a seat cushion, the seat cushion cover is shown with plastic ring, 34, at each end to hold an optional shoulder carrying strap (not shown).

Referring now to FIG. 5 a left side, planar view of a seat cushion, seat cushion cover is illustrated with nylon strap handle, 32, sewn to the cover front, used for the purposes of easily carrying the seat cushion assembly by hand. The seat cushion has fabric covered cording, 26, along the top and bottom edges. The seat cushion cover is shown with a side pocket comprised of polyester elastic net mesh, 28, within which to place items, pleats, 44, and an elastic band to hold and contain items such as a cell phone, water bottle, or keys, among other things. The seat cushion cover is also illustrated with nylon zipper, 36, that is positioned on the back side and wraps around the two back corners to allow for inserting and removing the seat cushion.

Referring now to FIG. 6, a back side, planar view of a seat cushion, the seat cushion cover is shown with vinyl material, 22, and cording with fabric covered cording, 26. The seat cushion cover is also illustrated with nylon zipper, 36, that is positioned on the back side and wraps around the two back corners to allow for inserting and removing the seat cushion.

Referring now to FIG. 7, a right side, planar view of a seat cushion, the seat cushion cover is illustrated with vinyl material, 22. Nylon strap handle, 32, is sewn to the cover front, to be used for the purposes of easily carrying the seat cushion assembly by hand. The seat cushion cover is also shown with plastic ring, 34, at each end to hold an optional shoulder carrying strap (not shown). The seat cushion cover is further shown with a pocket located on an end comprised of polyester elastic net mesh, 28, within which to place items, pleats, 44, and elastic bands, 42, to hold and contain items.

Referring now to FIG. 8, a top, planar view of a seat cushion, seat cushion, 10, is displayed.

Referring now to FIG. 9, a front, planar view of a seat cushion, the cushion, as it appears without a cover placed over it, is shown. Reticulated filter foam, 14, is shown in alternating layers with another foam type, closed cell polyethylene, 12. Reticulated filter foam, 14, gives softness to the weight distribution and suspension system while closed cell polyethylene, 12, prevents reticulated filter foam, 14, from compressing, to a state that is nearly or completely flat against the underlying surface, by displacing the downward force on the seat cushion to the entire surface area of the seat cushion. By laminating the layers together on each side with adhesive, 16, horizontal and vertical movement of an individual layer is prevented.

Referring now to FIG. 10, an internal cross-section side, planar view of a seat cushion, the cushion, as it appears without a cover placed over it, is shown. Reticulated filter foam, 14, is shown in alternating layers with another foam type, closed cell polyethylene, 12. Reticulated filter foam, 14, gives softness to the weight distribution and suspension system while closed cell polyethylene, 12, prevents reticulated filter foam, 14, from compressing, to a state that is nearly or completely flat against the underlying surface, by displacing the downward force on the seat cushion to the entire surface area of the seat cushion. By laminating the layers together on each side with adhesive, 16, horizontal and vertical movement of an individual layer is prevented.

Referring now to FIG. 11, a cross-section side, planar view of a seat cushion, 10, is shown with the features and accessories on the sides and edges, but without vinyl material, 22, shown on the edges in order to see the cushion foam layers, closed cell polyethylene, 12, and reticulated filter foam, 14, in a cross sectional view. Seat cushion cover, 20, is illustrated with a cover comprised of vinyl material, 22, and cording with fabric covered cording, 26. The edges of seat cushion cover, 20, are finished and sewn using cording with fabric covered cording, 26. Seat cushion cover, 20, includes vinyl material pocket, 46, that can be used to hold thin items. Seat cushion cover, 20, is illustrated with nylon strap handle, 32, sewn to the cover front, used for the purposes of easily carrying the seat cushion assembly by hand. Seat cushion cover, 20, is illustrated with plastic ring, 34, at each end to hold an optional shoulder carrying strap (not shown). Seat cushion cover, 20, is also illustrated with nylon zipper, 36, that is positioned on the back side and wraps around the two back corners to allow for inserting and removing the seat cushion. Also, reticulated filter foam, 14, is shown in alternating layers with another foam type, closed cell polyethylene, 12. The foam layers are laminated together on each side with adhesive, 16; horizontal and vertical movement of an individual layer is prevented. Low density high elasticity open cell foam, 18, is shown added to the top side of the cushion between closed cell polyethylene, 12, and vinyl material, 22. The addition of this soft type foam adds another dimension of comfort to the seated user.

In one embodiment of the present invention, a weight distribution and suspension system for a human body in a seated position comprising a plurality of foam layers of alternating types, densities, and elasticities is incorporated into seat cushion, 10, and seat cushion cover, 20 with various features. Seat cushion, 10, and Seat cushion cover, 20, comprise a plurality of foam layers of alternating densities and elasticities, closed cell polyethylene, 12 and reticulated filter foam, 14, vinyl material, 22, a second layer of vinyl, covering the top surface and creating vinyl material pocket, 46; cording with fabric covered cording, 26; a mesh pocket for holding small items, comprised of a polyester elastic net mesh, 28, within which to place items, pleats, 44, and elastic bands, 42, nylon zipper, 36, nylon strap handle, 32, and with plastic ring, 34, at each end to hold an optional shoulder carrying strap.

In this embodiment of the invention, the varying foam layers, closed cell polyethylene, 12 and reticulated filter foam, 14, may be laminated together with adhesive, 16, or may be left not laminated. Additionally, the layers may be held together at various layers by any combination of laminating or not laminating the various layers. In this embodiment of the invention, the foam layers may also be of varying degrees of thickness, providing varying degrees of softness and retention of softness.

In this embodiment of the invention, one or more layers of foam may be reticulated filter foam, 14, or closed cell polyethylene, 12. Additionally, one or more layers of foam may use flexible polyurethane foam, which may include high density, high resilience polyurethane foam.

In this embodiment of the invention, the weight distribution and suspension system creates comfort to the human body seated on the cushion by displacing weight and downward force on the cushion over a plurality of foam layers of alternating types, densities, and elasticities, closed cell polyethylene, 12 and reticulated filter foam, 14. This disbursement of body weight takes place not only over the top surface of seat cushion, 10, but also over the horizontal surfaces of each laminated foam layer, closed cell polyethylene, 12, then reticulated filter foam, 14, then closed cell polyethylene, 12, then reticulated filter foam, 14, then closed cell polyethylene, 12, for example. When weight is applied to the center area of seat cushion, 10, there is minimal compression created below, thus creating greater comfort to the seated user.

In this embodiment of the invention, each layer of closed cell polyethylene, 12, is three eighths of an inch in thickness. Additionally, each layer of reticulated filter foam, 14, has 30 pores per inch and is one inch in thickness. Additionally, the seat cushion is comprised of five of these alternating layers, closed cell polyethylene, 12, then reticulated filter foam, 14, then closed cell polyethylene, 12, then reticulated filter foam, 14, then closed cell polyethylene, 12. It is noted that the thicknesses and number of layers can vary in this cushion to increase or decrease the softness and comfort of the cushion.

In this embodiment of the invention, the shape of seat cushion, 10, and seat cushion cover, 20, is rectangular with radius corners. The size of the seat cushion, 10, is 11½ inches by 16 inches by 3½ inches. However, other sizes are possible while still using the weight distribution and suspension design.

In a second embodiment of the present invention, a method is disclosed for making seat cushion, 10, utilizing a weight distribution and suspension system for a human body in a seated position comprising a plurality of foam layers of alternating types, densities, and elasticities, closed cell polyethylene, 12, and reticulated filter foam, 14, interchangeably. This method is comprised of selecting foam layers of one or more foam types, densities, and elasticities, closed cell polyethylene, 12 or reticulated filter foam, 14, selecting foam layers of one or more foam thicknesses, selecting whether the foam layers, closed cell polyethylene, 12 or reticulated filter foam, 14, will be laminated to one another with adhesive, 16, laminating foam layers to one another if selected, assembling a plurality of foam layers, comprised of closed cell polyethylene, 12, and reticulated filter foam, 14, with vinyl material, 22, attaching cording with fabric covered cording, 26, and attaching accessories such as nylon strap handle, 32, plastic ring, 34, at each end for an optional shoulder strap, and a mesh pocket comprised of polyester elastic net mesh, 28, pleats, 44, and elastic bands, 42.
