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: An impact resistant wrapping system of the invention has a sheetlike wrapping body (1) formed of gas-barrier flexible wall members (11) and (12) between which wall chambers (14) closely partitioned or partially joined to one another are formed. The sheetlike wrapping body (1) is provided with an intake tap (3) capable of injecting gas into the wall chambers and exhaust taps (5) for releasing the gas from the wall chambers (14), which intake and exhaust taps are integrated so as to be used in common or formed separately. The exhaust taps (5) are arranged between the closely partitioned wall chambers (14) in one line or two or more lines intersecting to the wall chambers (14) so that the adjacent wall chambers (14) communicate with one another through the exhaust taps (5), thereby allowing the exhaust tap (5) of the outermost wall chamber (14) to communicate to the outside of the sheetlike wrapping body (1).
