Abstract
Disclosed are impact sensor arrangements for active hood systems, methods for making and for using such impact sensor arrangements, and motor vehicles with active hood systems using such impact sensor arrangements. Disclosed, for example, is an impact sensor arrangement for an active hood system of a motor vehicle. An active hood system actuator is selectively actuable to displace the vehicle's engine hood. The impact sensor arrangement includes a sensor connected to a sensing tube to detect a characteristic change of the sensing tube and responsively output an actuator trigger signal. First and second blocks, each formed from a high-density material, attach to the vehicle body adjacent the bumper and collectively define an internal channel within which is nested the sensing tube. The first block is movably attached to the second block such that displacement of one block with respect to the other initiates the characteristic change of the sensing tube.
