Fastening for a safety belt buckle, which is equipped for measuring the belt force arrangement
First Claim
1. A fastening arrangement for a safety belt in a vehicle, comprising:
- a holder for securement to said vehicle, wherein said holder is provided with a T-shaped head having arms that extend laterally relative to a longitudinal axis of said holder;
a connector that is moveably disposed, against spring action, on said holder, wherein said connector is adapted to be connected to a belt buckle or a belt strap loop, and wherein said connector is provided with abutments positioned opposite said arms of said holder;
a magnet and a magnetic field sensor disposed on said holder and said connector, wherein a relative movement between said magnet and said magnetic field sensor caused by displacement of said connector relative to said holder, which displacement is effected by tension acting on said safety belt, is converted into a signal that corresponds to the acting belt force;
first springs provided on outer longitudinal sides of said holder and said connector, wherein respective ones of said first springs extend between each of said arms of said holder and an oppositely disposed abutment of said connector, and wherein said first springs counteract a tension force of said safety belt or said belt buckle; and
a compensation spring that is disposed between, and is respectively supported on, said holder and said connector, wherein said compensation spring, without a tension force acting on said connector, prestresses said connector relative to said holder against nearly relaxed ones of said first springs with a spring force that is set low.

Abstract
A fastening arrangement for a safety belt is provided and includes a holder for securement to a vehicle. The holder has a T-shaped head with laterally extending arms. A connector is moveably disposed, against spring action on the holder and is connected to a belt buckle strap loop. A magnet and magnetic field sensor are disposed on the holder and connector. Relative movement between them, caused by displacement of the connector relative to the holder, is converted into a signal that corresponds to acting belt force. First springs are provided on outer longitudinal sides of the holder and connector and respectively extend between the arms of the holder and an oppositely disposed abutment of the connector to counteract tension force of the safety belt or buckle. The compensation spring is disposed between the holder and connector and, without a tension force acting on the connector, prestresses the connector relative to the holder against nearly relaxed first springs with a low spring force.
