Safety air curtain for vehicles

摘要

An inflatable safety air curtain device for vehicles includes an air curtain device (1) mounted in the car in front and above the driver or the passengers and an infrared detecting device (2). The air curtain device (1) consists of an inflatable air curtain (17) furled on a shaft (16) within a housing (11) or compressed and folded up within the housing (11). The infrared detecting device (2) is mounted at a farthest front end of the car and may, upon detecting any car or object within a critical range of the car, actuate an electromagnetic valve (13) on the air curtain device (1) to cause compressed air within the cylinder (12) to flow in to the air curtain (17) to inflate the same so that the air curtain (17) swells instantly downward to form a protective curtain (17) for the driver or the passenger.
