摘要

Collision-detecting device comprises a unit for determining the flow value of a fluid flowing through an opening and a collision-detecting unit for establishing whether a collision has taken place based on the determined flow value. The device also has an element defining a deformation chamber which deforms in the event of a collision between a vehicle and an obstacle. Preferred Features: The fluid is air and the opening is an outer region of a vehicle. The element is a tube (15) enclosing the deformation chamber.
