Abstract: A physical protector has a bag member (10) formed of gas-barrier seal members (1,2) different in deformability, and a valve (a) by which an air passage is formed by exerting a pushing force to the seal members (1,2) to elastically deform the seal members and closed by releasing the pushing force to resume the original shape of the seal members. The physical protector is attached to physical parts such as the human trunk or limbs and inflated by operating the valve (a) to introduce air into the bag member (10), thus protecting the physical parts. Since the air can be arbitrarily introduced into or discharged from the bag member by operating the valve (a), the protector can be used repeatedly. The valve (a) is made flat and compact so as not to give the user an unpleasant feeling.

Abstract: A soccer helmet includes a generally dome-shaped padding layer and a generally dome-shaped shell layer fitting over and attached to the padding layer. The padding layer might have a substantially uniform thickness of approximately ⅜ inches. The shell layer is smooth and has some rigidity such that when the soccer helmet is being worn on a human head, the ball rebounds from the shell layer in about the same direction and with about the same speed, or with a greater speed, than the soccer ball would if rebounded off an unprotected human head. Therefore, the soccer helmet does not interfere with heading a soccer ball. The soccer helmet protects the head from repetitive blows due to, for example, heading. Furthermore, the soccer helmet protects the head from single event injuries such as collisions with goal posts, the ground, and other players' head, knee, elbows, and feet.
