Abstract

Abstract An arrangement for actuating one or more motor vehicle safety devices in a collision with an obstruction. The arrangement includes an impact or deceleration sensing switch for connecting safety device actuators to a power source when an impact or deceleration rate greater than a predetermined magnitude is sensed, and a mechanical pressure sensing switch for rendering the actuators inoperative as long as no mechanical pressure is applied thereto.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 104 words
A safety device actuating arrangement for actuating a safety device of a motor vehicle, which comprises: at least one actuator for the safety device when energized; a normally-open deceleration rate detecting switch for connecting said actuator to a power source so as to energize said at least one actuator when it is subjected to a deceleration rate greater than a predetermined magnitude; and a normally-closed mechanical pressure detecting switch connected in parallel with said at least one actuator and in series, through a resistor, with said deceleration rate detecting switch, said mechanical pressure detecting switch being opened when a mechanical pressure is applied thereto.
Claim 2
Dependent Claim 104 words
