Patent ID: 7525416

Claim:
A device for detecting a collision with an object on a collision location detection region of a vehicle, comprising: first and second substantially closed hollow bodies, said hollow bodies: being connected to a part of a vehicle bodywork; having a longitudinal axis disposed parallel to the collision location detection direction and overlapping one another in the collision location detection region; and being disposed in a vicinity to an exterior surface of the vehicle such that at least one of said hollow bodies is compressed during the collision; a first sensor and a second sensor disposed to detect a compression of a respectively associated said first and second hollow bodies respectively, and configured to output first and second signals, respectively, indicative of the respective compression; and an evaluator connected to receive the signal from each sensor; said first hollow body having at least one first constructional parameter associated therewith and said second hollow body having at least one second constructional parameter associated therewith, with at least one of said constructional parameters varying along the collision location detection direction so that a quotient of the first and second signals increases or decreases in an event of a collision of a given object with identical velocity at different collision locations along the collision location detection direction.
