ABSTRACT:
The specification discloses a passive restraint system for high speed vehicles utilizing inflatable bags placed in the backs of the seats of the vehicle. The bags are connected by headers to a manifold which communicates with the exterior of the vehicle and, when open, allows air at high speed to enter and inflate the bags. A relief valve is provided in the cabin to open moments before the bags inflate to remove any danger of pressure shock from the rapid inflation of the bags and to, in some cases, aid in the inflation thereof. In some applications, an optional compressed air and/or compressed gas supply is also disclosed.
