Deformation sensor for a safety device for the protection of vehicle occupants in the event of a side-on collision
First Claim
1. Deformation sensor for a safety device for the protection of vehicle occupants against a side-on collision, which is composed of at least one pressure-sensitive signal element and which is arranged in a side region of the motor vehicle, at least one signal element being integrated into a protective strip mounted on an outside surface of the shell of the vehicle, the protective strip having integrated signal elements forming an elongate sectional bearer which can be compressed by a perpendicular force effect exceeding a specific threshold, with the result that the signal elements respond, wherein a predetermined threshold of the signal element is so high that, in the event of a perpendicular force effect on the protective strip, the shell is deformed, without a signal element being triggered, until a reinforcing profile arranged behind the shell opposes a further deformation of the shell, whereupon at least one signal element is loaded with pressure and responds.

Abstract
A deformation sensor for a safety device for the protection of vehicle occupants against a side-on collision is disclosed. The deformation sensor is composed of two pressure-sensitive signal elements arranged in parallel and one behind the other, so that the deformation speed can be concluded from the time sequence of the sensor signals. The signal elements ace integrated into a protective strip of the vehicle mounted on the outside of the shell. This ensures a rapid response in the event of a collision, and moreover the assembly of the deformation sensor becomes much easier. The signal elements take the form of FSR foil pressure sensors (Force Sensing Resistor).
