Problems solved by technology

However, in a situation where the patient is wearing a helmet, as often happens in motor sports, it may be difficult or impossible to install a neck brace without moving the head or neck, which would also increased risk of neck injury
Attempts to remove the helmet from the patient's head are also dangerous as this could cause movement that could cause or exacerbate injury

Embodiment Construction

[0024] Referring to the drawings, a helmet according to the invention is generally indicated by the reference numeral 10 .

[0025] The helmet 10 includes a first or inner cover layer 12 of a resilient material, such as fiberglass, carbon fiber, or a suitable plastic material, which is similar to the outer cover layer of a conventional helmet and shaped to generally surround the The wearer's head 14 is extended. Also like in conventional helmets, inside the inner shell 12 , the helmet 10 includes a support structure in the form of layered polystyrene foam 16 and padding 18 to support the shell 12 on the head 14 . In order to hold the helmet 10 on the head 14, it includes a chin strap 20 connected to the cover 12 by means of rivets 22, which can be connected by releasable clamps (not shown), and the chin strap 20 Extends around the wearer's jaw.

[0026] On the outside of the shell 12 , the helmet has an impact absorbing member in the form of a layer 24 covered by a tough out...

Abstract

A helmet (10) is provided, that has a first resilient shell (12), a support structure (16, 18) inside the first shell to support the first shell on the wearer's head (14), a chin strap (20), to hold the helmet in position, a deformable layer (24) on the outside of the first shell and a tough outer shell (26) on the outside of the deformable layer. The deformable layer is of a material that absorbs energy when it is deformed and returns slowly to its original shape afterwards. The helmet includes a chin bar (34) with two opposing ends (36) that are displaceable relative to the outer shell, immediately inwardly of the outer shell. The outer profile of the helmet has a plurality of generally planar surfaces (28) and the helmet has a rear strap (38) that is attachable to the chin strap and that is configured to extend around the back of the wearer's head.

Description

technical field [0001] The present invention relates to helmets. Background technique [0002] Typically, helmets designed to protect the wearer's head from injury are of "full-face" or "half-face" construction and include a tough, resilient shell, usually of composite material or with plastic, thick polystyrene foam layers, and fabric The padding, usually has a thin soft padding for comfort. [0003] To prevent injury to the head during activities such as motor sports, helmets known as "full face" helmets are often worn on the head as a precautionary measure, and the helmets generally include A hood that extends over the wearer's head, and a so-called "jawguard" that extends across the lower part of the wearer's face. The jaw is usually formed integrally with the cover and is spaced from the wearer's mouth and nose to allow him to breathe easily. [0004] When there is a full frontal impact on the chin guard of a full face helmet, said impact is transmitted via the attac...
