An apparatus includes a deployable supplemental inflatable restraint, which, after a deployment, vents supplemental inflatable restraint internal contenst to a vehicle passenger compartment, a signal line for sensing deployment of the supplemental inflatable restraint, a command generator for developing a command responsive to the sensed deployment, and an atmosphere control system for providing a flow of fresh air into the vehicle passenger compartment responsive to the developed command.

Automatic venting supplemental inflatable restraint system

An occupant restraining inflatable cushion apparatus includes a gas generator which generates a hot gas to inflate an inflatable fabric cushion of nylon-like material which is packaged about the gas generator in a deflated condition. The improvement comprises at least a portion of the inflatable cushion closest to the gas generator being a fabric having high temperature resistive properties whereby the the high temperature generated by the gas generator is prevented from pyrolizing the inflatable cushion. The high temperature resistive fabric may be fashioned as a liner which wraps around a metallic heat shield and is interposed between the heat shield and the nylon-like fabric. Alternatively the inflatable cushion may be fabricated of two different types of materials with the high temperature resistive material being used in those areas closest to the gas generator and the conventional nylon-like fabric used for the remainder of the bag more distant from the gas generator.
