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.
