A dual functioning head protection device for a fall prone user including a c-shaped neck collar that is configured to compress the jugular veins of the user during application to the user's neck and an expandable airbag helmet that is removably affixed to the collar. The airbag helmet includes an inflatable innerbag surrounded by an outer hag, such that the structure of the outer bag defines a shape of the airbag helmet when the inner bag is inflated. The inner bag includes a number of chambers which inflate to protect the user's skull during a fall. A trigger device in the collar detects if the user is falling and inflates the airbag helmet in such instances. This dual functioning device also protects the user's brain from brain slosh because of the collar's compression of the user's jugular veins. Compression of the vein sends blood into the skull with each fall impact, which reduces the brain's freedom to jostle around in the skull in a fall.

There is also provided a self-sustainable body-cooling garment for cooling a body portion of a human or an animal adapted to use the air pumping footwear and a cooling system for cooling the human or animal's body. There is provided a footwear comprising an air pump adapted to pump air when worn by a human or an animal during a pedestrian movement and to store or direct the pumped air for use by a cooling system for cooling the pumped air and using the cooled air for cooling the human or the animal. There is also provided a cooling system comprising an air pump adapted to be embedded within a footwear and a nozzle adapted to cool air pumped using the footwear when worn by a human or animal during a pedestrian movement.

An apparatus having a plurality of inflatable members, the inflatable members worn in a vertical orientation on a human torso; a collar portion connected to the plurality of inflatable members; and at least one inflation tube connected to the plurality of inflatable members, wherein the inflation tube includes a mouthpiece and a valve to controllably inflate and deflate inflatable members in the plurality. The apparatus is worn by a person underneath a protective vest to provide ventilation of body heat between the person and the protective vest.

An airbag module comprises a control unit, a source of electric current managed by the control unit, a container wherein a gas is stored under pressure, and a hollow body with an inlet duct, in which an outlet of the container sealed by a pierceable membrane is tightly fitted, and an outlet duct on which an inflatable bag is tightly assembled. The airbag module further comprises an actuator assembly configured to pierce open the membrane sealing the container, said actuator assembly comprising a piercing member movably restrained to the body and at least one linear shape memory alloy wire actuator member that is electrically connected to the source of electric current and operably restrained to the piercing member so as to cause it to move beyond the pierceable membrane.

A wrist protector includes a contact pad to be worn on a wrist of a user, a plurality of air tubes disposed on the contact pad, a pump configured to inject air from an outside into the plurality of air tubes, and a discharge valve configured to discharge the air stored in the plurality of air tubes to the outside.

A garment includes a first panel provided on a limb portion with a first lacing guide coupled to the first panel. The first panel is an elastic fabric panel. The garment further includes a second panel provided on the limb portion with a second lacing guide coupled to the second panel. A cord extends between the first lacing guide and the second lacing guide. A cord adjustment mechanism is coupled to the cord. The cord adjustment mechanism is configured to reduce an effective length of the cord extending between the first lacing guide and the second lacing guide such that the first panel is stretched and the first panel is drawn toward the second panel.

A head mounted display (HMD) device that includes a plurality of sensors, an actuator, a plurality of protective mechanisms, and a processor configured to identify a situational state of a user of the HMD device within a proximity of the user, based on sensor input received from the plurality of sensors. A risk-level of a potential injury to the user from a component of the HMD device is determined based on the identified situational state and the sensor input. A protective mechanism is selected from the plurality of protective mechanisms based on the identified situational state and the determined risk-level. The actuator is controlled to deploy the selected protective mechanism to mitigate injury to the user from the component of the HMD device, based on the identified situational state and the determined risk-level.

A garment worn on the upper body is provided with a back support system that can be selectively actuated as needed, and otherwise remains relatively unobtrusive when not actuated. The back support system includes a selectively inflatable and deflatable air bladder positioned at a desired location on a rear part of the garment opposite a portion of the wearer's back that needs support. Preferably, the air bladder is disposed within a pocket or compartment, preferably defined on an interior side of the garment, thereby leaving the exterior of the garment relatively unaltered in a visual sense. In a particular example, the air bladder of the present invention has a physical configuration designed to support specific portions of the spinal column as well as adjoining musculature.

A helmet having non-bursting gas cells preferably includes a hard helmet shell, an outside gas cell impact layer and an inside gas cell impact layer. The outside gas cell impact layer preferably includes at least one gas cell layer and an outside layer of sheet material. Each gas cell layer includes a plurality of gas cells created between two plastic sheets. The inside gas cell impact layer includes the at least one gas cell layer. The inside and outside gas cell impact layers may be permanently or removably attached to hard helmet shell. A second embodiment of the helmet having non-bursting gas cells preferably includes the hard helmet shell, the outside gas cell impact layer and an inside gas cell inflatable impact layer. The inside gas cell inflatable impact layer preferably includes at least one inflatable gas cell layer and a check valve.

An apparatus having a plurality of inflatable members, the inflatable members worn in a vertical orientation on a human torso; a collar portion connected to the plurality of inflatable members; and at least one inflation tube connected to the plurality of inflatable members, wherein the inflation tube includes a mouthpiece and a valve to controllably inflate and deflate inflatable members in the plurality. The apparatus is worn by a person underneath a protective vest to provide ventilation of body heat between the person and the protective vest.
