  • Safety air curtain for vehicles
    Patent number: 5599042

The infrared detecting device 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 on the air curtain device to cause compressed air within the cylinder to flow into the air curtain to inflate the same so that the air curtain swells instantly downwardly to form a protective curtain for the driver or the passenger.
