Collision sensor system for pedestrian protection

摘要

An impact sensor system for pedestrian protection, and a foil-type switching element having at least one operating regions. The foil-type switching element, provided and arranged in a certain distance by a spacer of at least one first carrier foil and a second carrier foil at least a first spacer of the first one, the operating region at least said I comprises a plurality of recesses defining a first portion of the house. In regions of operation, the electrode structure of two, pressed together against the reaction force of the carrier foil is elastic the carrier foil of the first and second in response to a force acting on the active area of ​​the switching element at least is, electrical contact to be established between the electrode structures of said at least two if it exceeds a threshold predetermined actuation force is disposed between the carrier foil and the second 1 . In accordance with the present invention, the foil-type switching element, the activation threshold force of the first group of the operations of the plurality of regions, the threshold operation of the second group of the operations of the plurality of regions configured to be different from the power.
