RELATED APPLICATION

This application claims priority to U.S. Provisional Application No. 60/583,900, filed Jun. 29, 2004, entitled “Flexible Seat pocket and Storage Apparatus,” which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to seats with removable article holders or receptacles. More particularly, the present invention relates to stadium and theater seat covers having storage pockets disposed therein for storing articles.

BACKGROUND OF THE INVENTION

Stadiums, theaters, and other sporting and entertainment venues generally provide seating for viewers and spectators with rows of flip-down style seats. These venues are designed to seat a large number of people in a given area, which can result in limited storage room for coats, hats, gloves, handbags, books, programs, and other personal items. While limited space might be available on the floor in front of the spectator or under the seat, any items left in this space can become soiled from dirt, food, and beverage spills, or from the shoes of those in neighboring seats if they inadvertently step on or kick any items on the floor. Also, coats hung on a seatback can fall onto the floor and can also impede another spectator's space in an adjacent row. Handbags and purses might tempt thieves or pickpockets if left unattended on the floor or seatback. Items placed on the floor can also be accidentally left behind after an event and finding and retrieving these items can be difficult or impossible.

Many large venues are outdoors, such as sporting arenas or outdoor amphitheaters, at which seats can become wet or dirty from the environment. Further, these venues, whether indoor or outdoor, often offer a variety of food items, beverages, and other concessions that can be enjoyed by spectators during events. Unfortunately, food items and beverages are frequently spilled or left on the seats where they leave residue that can soil a later seat occupant's clothing. Personal items stored on the floor or seat can also become wet or dirty from spills or the environment. Movie theaters, in particular, also provide limited lighting in which to examine the seats and floor prior to sitting on the seat or setting down personal items on the floor for any dirt, food, or beverage residue left by a previous seat occupant.

As a result, there is a need for a seat storage apparatus that substantially addresses the problems inherent with conventional seating in stadiums, theaters, and other venues.

SUMMARY OF THE INVENTION

The present invention solves many of the problems associated with conventional seating in stadiums, theaters, and other venues, specifically the lack of storage and unclean seating surfaces, by providing a seat storage apparatus for storing articles relative to a seat.

In one aspect, the invention comprises at least a flexible first sheet, and a flexible second sheet coupled to the first sheet to define a first pocket having a first opening, the first pocket configured to selectively shroudably couple with a portion of a seat, and a flexible third sheet coupled to the second sheet and/or the first pocket to define a second pocket having a second opening, the second sheet and second pocket configured to store an article relative to the seat. In a further aspect, the first and second openings are generally oriented such that each is facing in opposite directions with respect to the other.

In another aspect, the invention pertains to a method for assembling or forming a seat storage apparatus for storing an article relative to a seat. The method can include providing a flexible first sheet, coupling a flexible second sheet to the first sheet to define a first pocket configured to selectively shroudably couple with a portion of a seat, and coupling a flexible third sheet to the second sheet and/or the second pocket to define a second pocket configured to store an article relative to a seat.
