Patent Images
1. A pedestrian protection system for a vehicle, the system comprising:
- at least one impact-detecting sensor;
a deformation element, the impact-detecting sensor and the deformation element are arranged between a crossmember and a bumper cover of the vehicle; and
a control unit analyzing signals from the at least one sensor, wherein the deformation element is configured as a deformable body with a cavity in which the at least one sensor is arranged and wherein the control unit detects a deformation of a structural profile of the deformable body from changes in an electromagnetic field in the cavity,wherein the deformation element is configured as a metallic cage.

Abstract
A pedestrian protection system for a vehicle, having at least one impact-detecting sensor and a deformable element that are arranged between a cross-member and a bumper cover of the vehicle, and a control unit that analyzes the signals of the at least one sensor. In order to reduce the amount of space required, the deformable element is designed as a deformable member that it has a cavity in which the at least one sensor is arranged and detects changes in an electromagnetic field in the cavity.
