Safety helmet

摘要

The present invention is for a safety helmet having a hard outer shell having a plurality of protective flexible air bags for protecting a person's head against blows to the helmet outer shell and having a shock absorbing face guard. Each air bag may have a plurality of cushioning air bags enclosure layers mounted to a thin foamed polymer shell lining. Each enclosure layer of each air bag has an interior filled with a resilient multi-cellular sponge like material, such as a shaped foamed polyurethane sponge, and has a plurality of air escapement openings sized to meter the release of air under impact to the helmet hard shell under predetermined pressure with a different air release pressure for each enclosure layer.

1. A safety helmet comprising:
a rigid outer shell formed of a polymer material and having inside and outside surfaces; a foamed polymer lining fixedly attached to the inside surface of said hard outer shell; and a plurality of cushioning air bags attached in layers to the inside of said hard outer shell over said foamed polymer lining, each layer of said plurality of cushioning air bags having a flexible air impervious enclosure, each said enclosure being filled with a resilient foamed polymer and each said enclosure having a plurality of apertures therein, and each said enclosure plurality of apertures being of a size and number different from at least one other said enclosure to thereby require a different predetermined force on the enclosure to expel air therefrom; whereby a safety helmet provides shock absorption therein for the safety of the wearer of the helmet.
