摘要： PURPOSE:To protect an airplane passenger surely in the event of crash and the like by forming an air bag, which is inflatable to fill the inside of the airplane, from a plurality of sack-shaped films in continuity up and down and to the left and light, and inflating this air bag through delivery of air when any abnormality of the plane body is sensed. CONSTITUTION:The condition of an airplane is judged by a control device on the basis of information concerning the state of plane body given from a sensor, and when any danger exists, an appropriate signal is sent to an air feeding/discharging device 2. Now this device 2 begins feeding the air into an air bag 1. The air bag 1 is inflated from below in sequence. Air blows out from small hole provided at the outer extreme of the air bag 1, and thereby passenger is supplied with air and also the pressure is adjusted. When control device 3 senses that the plane body has stopped due to landing on the ground or water, a discharge signal is sent to the air feeding/charging device 2 to perform air discharge, and the air bag 1 is shrunk quickly.
