Air bag type of passenger protectors for protecting passengers from being injured in a vehicle collision

摘要

A passenger protector of the air bag type is mounted in a vehicle. The passenger protector comprises a compressed gas supplying assembly (1) and an air bag receiving assembly (2) for receiving an air bag (33) which is connected to the compressed gas supplying assembly (1) by means of a power hose (3). The compressed gas supplying assembly (1) comprises a compressed gas container (13), a movable weight (6), a hinged link (8), a hinged lever (14) and a perforating pin (19). If there occurs a vehicle collision, the weight (6) is reliably operated in response to a mechanical shock caused by the vehicle collision and this causes the hinged link (8) and the hinged lever (14) to be sequentially turned and in turn causes the perforating pin (19) to be pushed so as to perforate a closed tip of the compressed gas container (13). As the closed tip of the gas container (13) is perforated by the perforating pin (19), the compressed gas is rapidly blown out of the gas container (13) and into the air bag (33) having an outer shape which is coincident with the human body by forming an upper junction point (38), a pair of middle junction points (39, 40) and a U-shaped junction line (41), thereby efficiently preventing a passenger from being directly struck on a vehicle body and in this respect, protecting the passenger from being injured.
