PROTECTIVE HEAD COVERING Filed Aug. 24, 1964 INVENTOR JOHN W. D ERR A T TORNE) United States Patent Office 3,2425% Patented Mar. 29, 1956 3,242,500 PROTECTIVE HEAD COVERING John W. Derr, 23 Cambridge Ave., Pleasant Ridge, Mich.
Filed Aug. 24, 1964, Ser. No. 391,715 8 Claims. (Cl. 2-3) This invention relates to protective head coverings and in particular to a laminated over-covering for protective head gear such as a football helmet.
The invention is directed to substantially reduce head and neck injuries due to impact forces, leverage forces, and twisting forces imposed on players in violent contact sports such as football. While some of these injuries are occasioned from direct impact forces, they are occasioned more frequently from the torque and leverage forces involved with face guards on the helmet which twist the head, neck, and shoulders. This may happen when the face guard becomes entangled or is grasped by an opposing player.
In the prior art protective equipment, the head gear or helmet is itself made of cushion material or is made of relatively rigid material and cushion-wise suspended on the wearers head. In both instances of prior art helmet construction, the face guard is rigidly secured to the helmet so that face guard twisting and leverage is transferred to the wearer. Also when substantially rigid helmet outer surface material is employed, opposing players are sometimes injured by contact with the rigid outer surface of the helmet.
One of the main causes of injury, especially to young players during their period of growth, is the face guard being rigidly secured to the helmet. The face guard becomes entangled or is grasped by an opposing player and the twisting forces on the face guard are directly impinged on the head and neck of the wearer. In this Way the wearers head is snapped backwards or to the side so that the force of the impact is increased by the leverage inherent in the extension of the face guard.
With the foregoing in view, it is a primary object of the invention to provide a laminated over-covering for a helmet which has an outer layer which is made of relatively thick spongy flexible material so that it may absorb the direct impact forces involved in contact and dissipate them over enlarged area, increased thickness, and an interval of time thereby substantially diminishing direct instantaneous impact.
An object of the invention is to provide a laminated over-covering for a helmet which has a stiff but yieldably flexible inner shell providing support for the face guard so that forces directed to the face guard are transferred to flexing and moving the over-covering relative to the helmet thereby dissipating the forces involved through its movement and during an interval of time when flexing and movement is occurring.
An object of the invention is to provide a displaceablc and yieldably flexible over-covering cushion and support for a football helmet and face guard which is displaceably mounted on the football helmet so that it absorbs and dissipates forces involved in violent contact and also is displaceably moveable relative to the helmet under excessive forces so as to bypass the contact force by permitting the over-covering including the face guard to be displaced from the helmet.
An object of the invention is to provide a substantially semi-circular collar on the base of the over-covering which depends below the helmet and head of the wearer into contact with the shoulder pads of the wearer so as to act as a base support which resists head-on and sideon contact relative to the wearer and which also acts as a fulcrum for twisting forces exerted on the face guard thereby relieving the wearers head and neck of the multiplied forces involved in the leverage exerted by the face guard.
An object of the invention is to provide a severable connection on the over-covering so that it may disconnect when excessive forces are involved to relieve the wearer of the forces.
These and other objects of the invention will become apparent by reference to the following description of a laminated over-covering singly and in combination with a football helmet embodying the invention taken in connection with the accompanying drawing in which:
FIG. 1 is a side elevational view of the laminated overcovering and facing guard mounted on a helmet partially showing a player and shoulder pads; partly in cross-section to show internal construction; showing a severable fastener attaching the laminated over-covering to the helmet, showing the helmet secured to the wearer by an elastic chin strap, and showing the face guard attached directly to the inner shell in dotted lines.
FIG. 2 is a face elevational view of the device such as seen in FIG. 1 but showing the over-cover cushionsupport secured by a severable chin strap and showing the vface guard connected to the inner shell through the outer cover, and
FIG. 3 is an enlarged view of the cross-sectional portion of FIG. 1 showing the structure in more detail.
Referring now to the drawing wherein like numerals refer to like and corresponding parts throughout several views, the protective laminated over-covering such as for a football helmet comprises an outer layer 10. The outer layer 10 is relatively thick and is made of relatively soft, elastic, resilient, springy material such as sponge rubber, synthetic resin foam, fibrous padding or matting carried in a rubber or synthetic resin binder, and similar materials. An inner layer or shell 12 lies inside the outer layer 10. The outer layer 10 and the inner layer shell 12 are bonded together in a laminate.
The inner layer or inner shell 12 is relatively thin, stiff but flexible, and strong. The inner shell 12 is formfitted relative to the helmet. The inner shell 12 fits over the outside of a helmet 14. The helmet 14 may have a hard outer surface layer 15 and a soft interior layer 16. The inner shell 12 of the protective laminated outercovering hugs the outer surface layer 15 of the helmet 14. Thus the protective laminated outer-covering frictionally engages the helmet. Thus the protective laminated outercovering and the helmet are movably mounted relative to one another and positioned relative to one another in frictional engagement.
A substantially semi-circular somewhat enlarged collar 17 is formed integrally with the outer-covering and depends below the helmet 14 and is adapted to lie substantially in contact with the wearers shoulder pads 18. A face guard bar 19 is connected to the inner shell 12 of the outer covering, such as by rivets. In FIG. 1 the face guard bar 19 is directly connected to the inner shell 12 by rivets. In FIG. 2 the face guard bar 19 overlies the outer cushion layer 10 and is connected to the inner shell 12 by rivets which extend through the outer cushion layer 10. In mounting the face guard bar 19 over the outer layer 10, FIG. 2, spacer sleeves may be used on the rivets or fasteners. In this regard the spacer sleeves surrounding the rivets prevent the material of the outer layer 10 from being compressed or crushed and provide a firm mechanical connection to the inner shell 12. A chin strap 22 may be used on the helmet 14 to position the head gear on the wearers head.
A snap fastener 20 may be employed if desired to make a severable mechanical connection between the inner shell 12 and helmet 14. A chin strap 24 connecting to the outer layer 10 may be used, FIG. 2. The chin strap 24 holds the outer layer 10 relative to the helmet 14 and also to the wearer. Obviously the chin strap 22 on the helmet may be also employed with the modification illustrated in FIG. 2 and the chin strap 23 on the outer layer 10 superposed thereon.
In use, the novel over-covering cushion and support provides the wearer with additional impact dissipating flexible material absorbing direct contact forces in the head and neck area. Additionally, the collar 17 directly impinges on the shoulder pads 18, and in a contact where the head is withdrawn and the shoulders elevated, the collar transfers force of the impact to the shoulder pads 18.
It will also be noted that the collar 17 protects the back and sides of the wearers neck and reduces the danger of direct impacts to the wearers neck. This protects the wearer from the rear and sides of the neck which is not possible in a helmet.
Since the face guard 19 is mounted on the inner shell 12, the forces directed to the face bar 19 are transferred to the material of the inner shell 12 and the forces are dissipated in the inner shell 12 over an area and over an interval of time. When twisting and leverage forces are exerted on the face guard bar 19, such as upwardly or sidewardly as seen in FIGS. 1 and 2, the torsional force of the impact is transferred to the resilient inner shell 12 and to the collar 17 which impinges on the shoulder pads 18 thereby relieving the head of the wearer from the full twisting forces and the leverage action of the face guard bar 19.
When the face guard bar 19 is inadvertently grasped by an opposing player or otherwise entangled or acted upon, the leverage of the face guard bar 19 is fulcrumed at the collar 17 and the twisting forces the leverage are directed away from the head of the wearer.
When the excessive forces are involved in excessively violent impacts to the outer shell 10 and/or the face guard bar 19, the flexible inner shell 12 deforms whereby the over-covering is free to be forcibly removed from the helmet 14; this dissipates the forces involved in the removal of the over-covering and its deformation and removal allows an interval of time for the dissipation of such force as well as a camming action occurring which turns the residual force away from the player.
When excessive forces are encountered such as in the embodiment of FIG. 2 wherein the chin strap 24 is secured directly to the over-covering, the over-covering flexibility allows it to deform and twist whereby the chin strap fasteners are canted or turned so that they unsnap permitting the outer covering and face guard to be driven from the helment 14 thereby permitting the force to dissipate and bypass the wearer. This also un-snaps the fastener means 20, if used.
Although but a few embodiments of the novel overcovering cushion and face guard flexible support have been shown and described in detail, it is obvious that many changes may be made in the size, shape, detail, and arrangements of the various elements of the invention within the scope of the appended claims.
