A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. A microphone, an amplifier and a speaker are mounted to the helmet. Speech of the individual wearing the personal protection system is picked up by the microphone and amplified speech is broadcast by the speaker. The speaker is outwardly directed so as to broadcast the speech out through the hood or toga covering the helmet.

Disclosed is a portable smart air helmet including a head protection member including tubes configured to be expanded and provide an elastic force when air is injected into the tubes, and configured to be contracted and foldable when the injected air is discharged, an electric air pump configured to inject air into the head protection member or discharge the air injected into the head protection member, an accident notification device installed on the head protection member and the pouch and configured to automatically transfer information on an impact when the impact is applied to the head protection member and the pouch, and a pouch configured to enable a user to carry the electric air pump and the head protection member from which air is discharged.

A bicycle helmet that fits over a surface of a head of a user generally includes at least one segment of flexible cell structures that form a radial honeycomb matrix movable between a folded condition where each side of the at least one segment is disposed generally parallel and an expanded condition where the radial honeycomb matrix of the at least one segment is configured to be expanded at least partially over the head of the user and arranged radially relative to the surface of the head of the user.

A device, system, and elements for providing customizable and regionalized head protection are disclosed. One or more protective elements and/or cushioning elements can be permanently or removably attached to a wearable shell, to provide an increased level of protection for a wearer. The size, shape, and composition of the one or more protective elements and/or cushioning elements can be varied to alter the level and location of protection provided by the head protection device. One or more accessories also can be included in the head protection device, such as light sources and reflectors to enhance the visibility of the head protection device and to provide illumination.

The present invention provides a head protection helmet comprising an impact resistant shell comprising: a cavity for accommodating a user's head and an array of crushable bodies having a hollow closed configuration, e.g. flutes in corrugated material 14,16, the crushable bodies each having an axis that extends outwardly from the cavity to absorb impact forces exerted along the direction of the axis.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. A microphone, an amplifier and a speaker are mounted to the helmet. Speech of the individual wearing the personal protection system is picked up by the microphone and amplified speech is broadcast by the speaker. The speaker is outwardly directed so as to broadcast the speech out through the hood or toga covering the helmet.

A foldable helmet for use in various athletic activities, and which includes a structure that facilitates folding the helmet into a compact position for storage and/or transport of same. The helmet includes an outer shell having an inner cavity, and one or more inner members positioned within the inner cavity that slideably engage same. The inner members are not fixedly attached to each other at any point, and are therefore slideable relative to each other. The helmet's inner member(s) and outer shell are made of flexible materials, whereby the helmet is foldable from an open position to a closed position. A packaged helmet assembly is also disclosed, including the foldable helmet and a storage container dimensioned so as to receive the helmet in its closed position.
