HIDDEN DOOR FOR AN AIR BAG RESTRAINT SYSTEM

摘要

An air bag restraint system (10) is housed within an interior trim product with a hidden door (12) that is opened when an air bag (30) is inflated for deployment into the passenger car or a vehicle. The door (12) is formed in a reinforced segment (38) of a layer of a low density rigid foam material (34) that forms the load bearing support for the interior trim product and a backing for an outer skin or decorative outer surface that forms the outer cover (32) of the interior trim product. The hidden door (12) is formed by the layer of low density rigid foam material one of which convolutions (42, 44) forms a door hinge and the other of which convolutions (46) forms a weakened tear seam which separates when the air bag (30) impacts thereagainst to tear the outer skin (32) for forming an opening therethrough for deployment of the air bag (30) into the passenger compartment of a vehicle.
