ABSTRACT:
A vehicle crush detecting device consists of an electrically conducting tube with an electrically conducting rod concentrically positioned within the tube along with insulating means positioned at at least two points between the rod and the tube to insulate the rod from the tube. The electrically conducting tube is deformed during a vehicle crash by a force greater than a predetermined magnitude which causes the tube to contact the rod in response to the crush of a vehicle of a predetermined amount. The crush sensor is mounted in the crush zone of the vehicle and is used in conjunction with automobile passive restraint systems such as airbags.
