Installation for detecting deformation of the automotive vehicle frame, due to a side impact on the vehicle due to a collision, and for triggering the side impact protection air bags

摘要

The installation has units for detecting the acceleration of the frame assembly (1) of the vehicle, e.g. side pillar at the level of the driver or passenger seats due to a side impact, and controlling the triggering of inflatable side impact protection air bags to protect the vehicle occupants. The construction assembly (11) of the vehicle has components (8) to detect the start of plastic deformation of a group, and to reduce the triggering threshold for actuating the side impact air bags.
