An air injection apparatus is provided according to one embodiment of the present invention. The air injection apparatus includes a main body in which an air passage is formed, and an opening and closing part which is coupled to one end of the main body and in which an opening and closing protrusion having a predetermined length, protruding toward the air passage, and configured to open or close the air passage is formed on an inner surface thereof, wherein at least a part of the opening and closing protrusion may be inserted into the air passage to seal the air passage when the opening and closing part is moved in a first direction toward the main body.

A vest includes a first panel including a first flap, a second panel including a second flap, a back panel extending from the first panel to the second panel, and a plurality of grips. The back panel defines a first and second arm accesses with first and second panels respectively, and portions of the first, second, and back panels disposed below first and second arm accesses define a body of the vest. The first flap is configured to overlap the second flap. The first flap includes a first front attachment segment configured to attach to a second front attachment segment of the second flap in a closed state of the vest. At least one embodiment or aspect may comprise at least one of the following features: at least one zipper expansion and retraction mechanism; and a leg attachment device for detachably securing a compression vest system to a user's leg.

An inflatable garment accessory including a body assembly and a sleeve assembly is disclosed. The body assembly includes an inflatable member that is made of a cloth material and has an interior space therein. The inflatable member may be rectangular in shape and further includes a font end. A user may then place indicia and/or designs to be accentuated on the front end of the inflatable member. The sleeve assembly includes two sleeve members made of cloth material that are mounted to opposite perimeter sides of the inflatable member. The two sleeve members form a tunnel which receive air therein. The air then inflates the inflatable member which in turn accentuates the indicia and/or design located at the front end.

There is no other self-inflatable football collar in the American football equipment market. Upon impact to the helmet, this collar is designed to catch in lower lip of the football helmet and transfer the force from the head and neck of the collar and shoulders.

The present invention is garments, articles of clothing, and body equipment systems having a bladder system for providing better fit of garments, articles of clothing, and body equipment systems to certain applicable body part(s) or area(s) of a user during use, and for providing greater support, comfort and/or stability to certain applicable body part(s) or area(s) of a user during use. As a non-limiting example, the present invention is compression garments having a clothing component and a bladder system, compression articles of clothing having a clothing component and a bladder system, and also to compression body equipment systems having a bladder system for providing better fit of compression garments, compression articles of clothing, and compression body equipment systems to certain applicable body part(s) or area(s) of a user during use, and for providing greater support, comfort and/or stability to certain applicable body part(s) or area(s) of a user during use.

A decubitus ulcers prevention garment for decreasing the skin pressure on a select body area of the population at risk for decubitus may be provided. The garment may be similar in shape to boxer briefs and composed of strategically mapped air cells for the patients' bilateral hips, proximal thighs and gluteal region wrapping posteriorly, targeting anatomic points including greater trochanteric, ischial tuberosities, posterior iliac spines, sacrum and coccyx. The air cell arrangement may allow for patterned inflation and deflation thereby off loading and loading particular areas. As air cells are cycled through inflation and deflation, skin pressure may be decreased thereby preventing focal pressure and local tissue ischemia resulting in necrosis.

Inflatable coveralls provide individuals, who fall frequently, with protection and independence. The coveralls consist of pads on the shoulders and hips to reduce the impact of a fall on the person. When worn and located underneath the fallen person, the coveralls can be inflated with air into a chair, creating a higher platform from which the person can more easily get up. This reduces the dependence these individuals have on a caregiver. Users can fasten the coveralls using hook & loop or magnets, instead of buttons or zippers, because it is easier to wear and they automatically open from the increase in air pressure of the inflated coveralls. Made of lightweight and air-impermeable material, the inflatable coveralls pads the fall of individual and elevated the fallen individual so that they can more easily rise, allowing them to gain independence.

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.

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.

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