TRIGGER SWITCH FOR MOTOR VEHICLE SAFETY DEVICES

摘要

A trigger switch mechanism for actuating motor vehicle safety devices responsively to deceleration of a given magnitude resulting from a collision of the motor vehicle. The mechanism comprises a cylinder mounted on the vehicle body in a horizontal manner with a cylindrical weight mounted within the cylinder chamber for axial movement so that when the trigger switch mechanism is subjected to deceleration of a given magnitude in the one direction, a force of inertia forces the cylindrical weight to move axially in the opposite direction, allowing an actuator pin to extend so that a micro-switch is closed.
