Abstract

An occupant restraint cushion made of a single sheet of woven material and having an upper compartment that is adapted to engage the windshield of a vehicle and be guided thereby rearwardly when deployed so that subsequently a lower compartment extends downwardly from the upper compartment and is inflated in a position between the driver and the steering wheel.

Claims

1. In combination with a vehicle body having an instrument panel, an occupant restraint cushion system located in said instrument panel and comprising a housing fixedly mounted to said vehicle body, a restraint cushion formed of a porous woven material and having at least two wall sections defining a compartment, a portion of said restraint cushion being secured to said housing, a gas generator located in said compartment for inflating said restraint cushion under predetermined conditions so as to cause the restraint cushion to be deployed outwardly relative to said instrument panel, one of said wall sections of said restraint cushion having a slit formed therein, and a patch located within said compartment covering said slit and fixedly connected to the associated wall section so as to provide a passage to the slit when an obstacle prevents full deployment of said restraint cushion to thereby relieve the pressure within the restraint cushion and prevent full inflation thereof.
