1. An accident sensor for triggering a safety system in a motor vehicle, comprising:
- a deformable and radiation transparent synthetic material part, wherein the material part is penetrated by a defined quantity of light traveling in a beam path; and
a radiation sensitive detector that optically detects a deformation of the material part by detecting a change in the beam path to determine a position of impact on the motor vehicle based a signal waveform and a determination of the transit time between impact and the detection of the signal, wherein the material part is arranged externally on the motor vehicle.

Abstract
An accident sensor for a motor vehicle for triggering a safety system is provided. A deformable and radiation transparent synthetic material part is penetrated by a defined quantity of light traveling in a beam path. A radiation sensitive detector optically detects the deformation of the material part by detecting a change in the beam path to determine a position of impact on the motor vehicle based a signal waveform and a determination of the transit time between the impact and the detection of the signal. The material part is arranged externally on the motor vehicle.
