ABSTRACT:
A method and apparatus for operating a seat-occupant restraining device in response to collision of a vehicle, comprising a front bumper on the vehicle adapted for receiving impact in the course of a collision and supported by a damper which opposes rearward displacement of the bumper. The damping is a function of the change of velocity of the vehicle during the collision and is used to displace a normally stationary part of the damper when the collision force exceeds a predetermined value. The displacement of the stationary part of the damper serves to close a switch to actuate the seat-occupant restraining device. The switch can be an acceleration detection switch in which case the stationary part is supported by the vehicle body by a deformable structure or the switch can be made as a deformable unit which undergoes deformation by the application of force thereto from the stationary part of the damper.
