AI Technical Summary

Benefits of technology

The present invention is a protective helmet with a lining layer that provides cushioning for the wearer's head. The helmet has a hard inner shell and a hard outer shell with an intermediate layer that dissipates forces from impacts. The inner shell is connected to the outer shell in a way that allows for displacement of the inner shell. The helmet also has a chin strap that attaches it to the wearer's head. The invention can be applied to different embodiments and in various ways.

Problems solved by technology

While these helmets are all significant improvements over the traditional monolithic helmets, they only allow limited rotational displacement of the inner shell with respect to the outer shell and consequently they only allow limited dissipation of energy.

Embodiment Construction

[0010]Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIG. 1 illustrates a cross sectional view of a protective helmet in accordance with a preferred embodiment of the present invention which includes a hard inner shell 104, a hard outer shell 100, an energy absorbing intermediate layer 102 between the inner shell 104 and the outer shell 100, a lining layer 106 on the surface of the inner shell 104, which is adjacent to and provides cushioning for the wearer's head, and a chin strap attached to the inner shell 104 by the use of a spacer 110 where the spacer is of a height that allows the chin strap to be flush with the outer shell 100.

[0011]Both the inner shell 104 and the outer shell 100 are made of a hard lightweight plastic material such as a polycarbonate alloy. The intermediate layer 102 is located between the inner shell 104 and the outer shell 100 and is attached to both the inner shell 104...

Abstract

The present invention relates to protective helmets used in activities where there is significant risk for head injuries. More specifically to helmets enhanced with a chin strap and multiple layers which are connected in such a way that compression and torsion forces applied to the helmet as a result of impact are significantly absorbed, reducing the risk of injury to the wearer's head.

Description

FIELD OF INVENTION[0001]The present invention relates generally to protective headgear and, more specifically to a protective helmet with multiple layers, enhanced to reduce and dissipate compression and torsion forces respectively in activities where there is significant potential for head injuries.RELATED ART[0002]Protective helmets have been used for many years to shield the wearers during activities where there is a risk of head injury. The first helmet ever invented was a monolithic leather structure with three leather straps which secure the helmet to the wearers head. Over the years, different materials became available and the structure of the helmet developed to incorporate padding as well as the implementation of plastics into the design. In more recent times there have been significant concerns over the increasing number of concussions occurring among American football players. This has led to a great deal of research into ways of decreasing the severity of the damages ca...
