<p>A body protective device comprising a bag (10) composed of two gas-barrier sealing members (1, 2) different in the extent of deformation and provided with a valve (a) which opens an air passage between the sealing members (1, 2) when they undergo elastic deformation by pressurization and closes the air passage as a result of elastic recovery of the sealing members due to depressurization. The human body can be protected by attaching the device to the trunk or the extremities and operating the valve (a) to introduce the air into the bag (10) to thereby inflate the same. By appropriately operating the valve (a), the passage of the air into and out of the bag can be effected at will and the device becomes reusable. As the valve (a) is small and comparatively flat, the device does not give the body a feeling of physical disorder. <IMAGE></p> |
