An airbag system including an airbag and a detachable shell enclosing the airbag when the airbag is in a non-inflated state, and at least one size adjustment mechanism. Further, an inflatable helmet having such airbag system, and an item of apparel having such airbag system are provided.

A helmet cover includes a cover configured to extend over a helmet and at least one mount attached to the cover. In one embodiment, a backing plate is coupled to the at least one mount and the cover is sandwiched between the backing plate and the at least one mount.

A waveguide based fused vision system includes a helmet mounted or head worn sensor module and a display assembly. The display assembly includes a frame including a pair of waveguide combiners and a pair of projectors associated with waveguide combiners. The display assembly also includes a sensor module. The pair of projectors is disposed on opposite sides of a frame. The sensor module is disposed substantially above the frame and includes a first sensor, a second sensor, a video processing circuit, and a symbol generator. The video processing circuit is configured to merge first sensor information from the first sensor and first symbols from the symbol generator and to merge second symbols and the second sensor information for displaying conformally the real world scene.

A protective insert for headgear includes a malleable main body member having an inside facing surface, an outside facing surface and an impact resistant material that is disposed between the inside and outside facing surfaces. A plurality of connectors are disposed along the insert, and removably engage complementary connectors positionable inside a traditional hat. A plurality of air vents are disposed throughout the main body, and the impact resistant material includes polyurethane foam and polyborodimethylsiloxanea, which is malleable in a non-compressed state, and becomes firm and rigid when receiving an impact force.

A helmet can include a helmet body comprising an energy-absorbing layer and an outer shell disposed over the energy-absorbing layer. An electronic device can be integrated with the helmet body. A first electrical contact can be formed at an exterior of the outer shell and adapted to be in electrical communication with the electronic device. A helmet visor can be coupled to the helmet body with at least one visor arm, the helmet visor comprising controls integrated within the visor. A second electrical contact can be formed at an inner surface of the at least one visor arm and adapted to be in electrical communication with the controls integrated within the visor. The second electrical contact can be adapted to mateably couple with the first electrical contact such that the electronic device and the controls are adapted to be in electrical contact.

A protective football helmet is provided having a two-piece mold shell diminution shell system. The helmet is comprised of a nine-piece part outer shell, a solid rim outer shell to deflect direct impact from the nine piece part outer shell, an inner liner helmet, compression springs as shocks, and a spin dial to control and restrict the movement of the compression springs and nine piece part outer shell. The nine piece part is a special designed helmet to absorb impact on contact from the crown of the helmet, all four sides and all angles in between to protect the players' head from direct contact at any angle. The outer shell diminution system is piece parted to absorb the impact energy individually by the outer shell protection. Each outer shell piece parted section takes on the impact of energy with an oval shape to deflect and transfer contact impact energy from one piece part to another, thereby dispersing the energy throughout the outer shell of the helmet.

The present invention is directed to a helmet holder. The helmet holder allows a helmet to be safely stored in a way that does not compress the internal foam or scratch exterior painted or colored surfaces. It uses four upright, angled tabs to prevent front-to-back and side-to-side motion while allowing the bottom surface of the helmet to rest on somewhat horizontal surfaces. Each of the four tabs has a projection for hooking a bungee net, allowing the helmet to be safely constrained. The holder also has hooks for holding hangable items such as keys. It is expandable to add hooks for smaller items such as gloves and an adapter for hangers to hang jackets or full body suits.

A safety integrated electrically powered vehicle (SIPV) apparatus comprising an electric vehicle further comprising at least an integrated safety control apparatus wherein the integrated safety control apparatus polls a plurality of sensors to detect current SIPV data related to safe use, a communication link to an integrated safety control apparatus to transmit a plurality of data representative of the current use of a SIPV, and receive from the SIPV system at least an instruction received from the integrated safety control apparatus via the communication link to direct a plurality of control units on the SIPV to modify current operation parameters to bring the SIPV back to a safe use.

A liner assembly for a protective helmet has a rigid shell with an inner surface and concave curvature having a front portion, a rear portion, a crown portion, a pair of opposite portions and a pair of opposite jaw flaps; a wrap-around pad has a plurality of circular cells spaced along a curved line around the inner surface, and at least one additional cell at each end of the curved line. Two jaw pads, each jaw pad removably engaged to a respective one of the jaw flaps, and each jaw pad has one cell having one cell with two curvilinear segments. Each cell of the wrap around pad and the jaw pads includes an outer sheet of thermoplastic and an inner sheet of thermoplastic.
