Description:

This invention relates to football helmets, one of the objects being to provide an inflatable helmet for cushioning any blows received thereby so that the force of the blow will be distributed - 5 evenly to all portions of the inner surface of the helmet and injury to the wearer thus reduced to the minimum.

A further object is to provide a helmet which, when not in use, can be deflated and thus compactly stored.

A further object is to provide a helmet the exposed surfaces of which are formed of rubber so that they will not absorb moisture and acquire objectionable odors.

A still further object is to provide an inflatable helmet having new and improved means for holding it in proper shape when inflated and for maintaining desired ventilation while being worn.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing Figure 1 is a side elevation of the helmet, a portion of one of the ear flaps being broken away.

Figure 2 is a section on line 2-2, Figure 1, taken through one side of the helmet.

Figure 3 is a section on line 3-3, Figure 1, taken through one side of the helmet.

Figure 4 is a section through one side of the helmet taken on the line 4-4, Figure 1.

In producing this helmet it is designed to provide a hollow wall the outer and inner sides I and 2 of which are of sheet rubber preferably molded to proper shape and joined to the inner surface of each of these sides is a reenforcing fabric 3 constituting a coextensive lining, the fabric being attached to the rubber sides of the wall by vulcanizing or in any other preferred manner. The fabric prevents the rubber from s5 stretching and also lends strength thereto so that danger of tearing, puncturing or otherwise injuring the helmet is materially reduced. In the drawing each side of the wall has been shown provided with a single thickness of fabric lining but it is to be understood that, if preferred, each side could be built up of two or more layers of rubber and fabric. The rubber can be molded to proper shape or otherwise formed and the free edge portions of the helmet are joined by a marginal binder 4 vulcanized or otherwise attached thereto and formed preferably of heavy rubber in the form of a channelled stfip, as shown particularly in Figure 3.

Interposed between the inner and outer sides. of the wall of the helmet are fabric stays in the form of webs having integral oppositely extending flanges 6 vulcanized or otherwise securely fastened to the inner surfaces of the wall sides. These webs 5 are formed with apertures 7 so that air can flow freely through them. The webs are disposed along lines diverging from the center of the top of the helmet toward the bottom or free edge thereof. These webs are so proportioned as to restrain the walls against spreading apart too far when the helmet is inflated. Further spreading of the sides is overcome by rows of rubber vent tubes 8 which extend through the sides of the helmet wall, each tube being provided at each end with spaced flanges 9 and 10 which lap the adjacent portions of the engaged wall and are vulcanized or otherwise joined thereto. These vents provide ample ventilation through the helmet and, as before stated, cooperate with the webs 5 to hold the helmet in proper shape when inflated. As shown in Figures 1 and 4 the lined sides I and 2 of the helmet wall are extended downwardly to form ear guards G each of which is provided with a desired number of vent tubes 8 which also permit the passage of sound waves. Extending from one of the ear guards is a side flap 11, consisting of spaced members 12 and 13 vulcanized or otherwise attached to the adjacent portion of the guard and extending downwardly therefrom. These members are joined along one edge for a portion of the distance thereof, as shown at 14, so as to provide a pocket 15 which can be closed by fastening together the remaining edge portions of the members. The fastening means used can be snap-fasteners 16 of the usual type. This pocket is adapted to receive an inflation tube 17 which is connected to and opens into the helmet at the edge thereof and, after inflation, is adapted to be folded and tied, as shown at 18 in Figure 1 so as thus to be supported entirely within the pocket where it is out of the way.

A strap 19 carrying a buckle 20 can be joined to the inner member 12 of the flap 11 and it is to be understood that the other side of the helmet can also be provided with an ear flap which need not be constructed as shown and which can have a strap joined thereto for engagement with buckle 20 in the usual manner thereby to hold the helmet securely on the head of the user. A 6 portion of this second strap has been indicated at 21 in Figure 1.

It will be obvious that the webs 5 and the vent tubes 8 will cooperate to hold the inner and outer sides of the helmet wall properly restrained when 10 the helmet is inflated by forcing air through tube !7 after it has been untied. The inflated helmet will retain its proper shape while in use and the air contained therein will, as before stated, serve to cushion any blow that might be struck upon 16 the outer portion of the helmet, the force of the blow being dissipated throughout the inner surface of the helmet so that injury to the wearer will be prevented.

As the exposed surfaces of the helmet are 20 formed of rubber, they cannot absorb perspiration or other moisture. Furthermore they can be cleaned readily so as not to acquire an objectionable odor. When the helmet is not in use it can be deflated and easily rolled into a small 26 package, folded or otherwise arranged for storage.

What is claimed is: 1. A one-piece helmet including a hollow, airtight wall of flexible material shaped to the head of a user and providing ear guards, restraining webs interposed between and connected to op- 6 posed inner surfaces of the wall and diverging from the center of the top of the helmet towards the free' edge thereof, said webs being apertured, and reenforcing vent tubes joining and opening through the inner and outer sides of the wall between the webs.

2. A helmet including a hollow, air-tight wall of flexible material shaped to fit the head of a user and to provide ear guards, restraining webs interposed between and connected to opposed inner surfaces of the wall and diverging from the center of the top of the helmet towards the free edge thereof, said webs being apertured, reenforcing vent tubes joining and opening through the inner and outer sides of the wall between the webs, a side flap extending from the helmet and providing a pocket, and an inflation tube opening into the helmet and normally housed within but extensible from the pocket.
