A safety device for the passenger's head against side impact of the vehicle (SIDE IMPACT HEAD STRIKE PROTECTION SYSTEM)

摘要

The present invention relates to a tubular structure (11) which expands when a side collision or an oblique direction collision of a vehicle occurs in order to protect a passenger of a vehicle such as an automobile.;The tubular structure 11 of the present invention is installed in a non-inflated state along the perimeter of the side supports 20, 21 and the roof rail 23 of the vehicle. The main component of the present invention is the tube 15 connected to the gas generator 22. When a side impact is detected, the gas generator 22 is actuated to inflate the tube 15. As tube 15 expands, the diameter of tube 15 increases and its length decreases. The tube 15 is withdrawn from the storage state to form a semi rigid, bulky structural member that traverses the side window 24 of the vehicle.
