Abstract

A sensor and bracket assembly designed for arrangement in the crush zone of a motor vehicle, is operative to determine when and if a crash of the vehicle is severe enough to deploy a passive restraint system (i.e., air bag or seat belt tensioner). The sensor is preferably of the crush switch type but may also be electronic of electromechanical. The bracket is designed to lie in the crush zone for a wide spectrum of crashes including those that involve only a portion of the vehicle front end including partial bumper over-rides and under-rides. The bracket may be either a separate part of the desired shape may be incorporated into the design of some part of the vehicle structure such as the radiator supports. The assembly may incorporate a single or multiple brackets and a single or multiple sensors. The essence of the invention is that the bracket is comprised of two ends and at least one deformable section which deforms in a predictable controlled manner upon the bracket being impacted in a crash condition desired to be detected. The bracket is placed a scientifically or otherwise predetermined distance back from the frontmost part of the vehicle depending on the crash and car spec…
