Abstract
Abstract An inflatable restraint housing for enclosing an air cushion assembly and securing the assembly within a vehicle is provided. The one-piece housing is formed of thermoplastic material and includes an inboard and outboard half hingedly secured together and enclosing the air cushion assembly in a tapered interior chamber. The housing is generally cylindrical having an inboard and outboard directing ramp formed on the respective inner surfaces of each half to define a tapering elliptical cross-section which focuses the energy generated by the inflation of the air cushion allowing the air cushion to rapidly emerge from the housing. The tapered interior chamber of housing also directs the air cushion into the desired position within the vehicle interior during deployment.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
152 words
An inflatable restraint housing for enclosing an air cushion assembly capable of deploying an air cushion into a vehicle interior, said housing comprising: a first half; a second half hingedly secured to said first half along a hinged edge, said first and second halves defining a tapered interior chamber which converges towards a deployment edge opposite said hinged edge; and a stiffening rib extending from said housing adjacent said deployment edge: said first and second halves configured for enclosing the air cushion assembly in a closed condition such that said tapered interior chamber can focus the energy generated by the inflation of the air cushion towards said deployment edge causing said first half to rotate with respect to said second half to an open condition and allow the air cushion to be deployed therefrom, said tapered interior chamber further configured for directing the deployment of said air cushion into a vehicle interior.
