Arrangement for detecting impermissibly high forces acting on the supporting structure of a vehicle
First Claim
1. An arrangement for detecting impermissibly high forces acting on a supporting structure of a vehicle comprising:
- a substantially conical housing;
two electrical contacts being arranged inside the housing for connecting a signal circuit indicating deformation when the housing is deformed;
said housing being deformable in a defined manner and essentially having the shape of a truncated cone, wherein a center axis joining centers of a base surface and a top surface of the truncated cone is oriented in the direction of an acting force to be detected;
a rod having a wedge-shaped end in the interior of the housing, said rod being rigidly fastened parallel to the center axis of the truncated cone to one of the base and top surfaces;
said electrical contacts being connected with a contact bridge within a glass tube by which a circuit is kept closed, wherein the glass tube is oriented orthogonal to the direction of the rod and transverse to the wedge-shaped end thereof; and
when the height of the truncated cone is reduced in excess of a determined amount due to the action of an impermissibly high force, the wedge-shaped end of the rod and the glass tube are displaceable relative to one another to an extent that the glass tube is broken and the contact bridge is interrupted.

Abstract
An arrangement for detecting impermissibly high forces acting on a supporting structure of a vehicle is disclosed. Impermissibly high forces acting on the supporting structure of a vehicle which indicates possible damage to the supporting structure are detected within a predefined impact or deformation range only in the case of impermissibly high forces, by the disclosed an arrangement. This arrangement for detecting impermissibly high forces acting on the supporting structure of a vehicle comprises a housing which is deformable in a defined manner and essentially has the shape of a truncated cone, wherein the center axis of the truncated cone is oriented in the direction of the acting force to be detected, there is a rod with a wedge-shaped end provided in the interior of the housing, wherein the rod is rigidly fastened parallel to the center axis of the truncated cone to the base surface or top surface, electrical contacts inside a glass tube with a contact bridge keep a circuit closed, wherein the glass tube is oriented orthogonal to the direction of the rod and transverse to its wedge-shaped end, and when the height of the truncated cone is reduced due to the action of an impermissibly high force the rod and the glass tube are displaced relative to one another to the extent that the glass tube is broken and the contact bridge is interrupted.
