ABSTRACT:
A horizontal passenger-restraining padded buffer (FIGS. 1 and 2) extends transversely across the front portion of the automobile passenger compartment adjacent to and overlying the cowl. This buffer is mounted on the outer ends of the piston rods of a pair of rearwardly-facing pneumatic cylinders tiltably mounted in spaced parallel relationship on the fire wall of the vehicle. The rearward chambers of the cylinders contain air and the normal retracting positions of the pistons are adjacent the forward ends of the cylinders. Secured to the forward end of each cylinder and communicating with the forward chamber thereof is an explosive gas generator which contains a cartridge chamber for a pistol blank cartridge adapted to be fired by a reciprocable firing pin actuated by an electrical solenoid to the armature of which it is attached. The solenoid is connected with a deceleration-responsive inertia switch which upon sudden deceleration of the vehicle closes the circuit to the solenoid winding, the energization of which propels the armature-connected firing pin sharply outward into contact with the detonator of the center-fire cartridge, firing it. The explosive gases generated by the firing of the cartridge enter the forward chamber of each cylinder. As a consequence, the piston heads of the two cylinders and their piston rods, together with the theretoconnected buffer, are propelled instantly at high speed rearwardly, against the passenger or passengers in the front seat of the automobile, at the same time compressing the air in the rearward chambers of the cylinders and forcing it through escape ports. The buffer thus counteracts the inertia of their bodies and holds them firmly against the back of the front seat, preventing them from plunging forward and preventing injury.
