Device for detecting collision with a vehicle
First Claim
1. In combination, a vehicle having a vehicle body with a part potentially affected by a collision, including relatively rigid vehicle body parts that are comparatively difficult to deform during the collision, and a device for detecting a collision, the device comprising:
- a substantially closed measuring volume disposed along the part of the vehicle body potentially affected by the collision, said measuring volume, along a longitudinal direction thereof, having a cross-sectional area with a comparatively larger area in a vicinity of the relatively rigid vehicle body parts that are comparatively difficult to deform during the collision; and
a pressure sensor disposed for detecting a change in pressure inside said measuring volume in order to detect a compression of said measuring volume upon the collision.

Abstract
A device for detecting a collision with a vehicle includes a pressure sensor for detecting compression of a substantially closed measuring volume upon collision. The measuring volume is arranged along a part of the vehicle body that is impacted during the collision. The cross-sectional area of the measuring volume, along its longitudinal direction, has a comparatively larger area in the vicinity of those parts of the vehicle body that are comparatively rigid and therefore comparatively difficult to deform during collision.
