Abstract
A force sensor, in particular for the determination of the forces on a vehicle seat, includes a force measuring cell ( ) having a Hall element. The force measuring cell ( ) contains a hollow-cylindrical flexible element ( ), which, based on the force effect (F) to be determined, causes an affect of the magnetic field in the region of the magnetic field-sensitive sensor element ( ) of the force measuring cell ( ). The hollow-cylindrical flexible element ( ) contains a bar ( ) on a relatively stationary end on a first support part with a magnet ( ) on its free end. The flexible element held on one support part ( ) projects into a top ( ) held on the other support part ( ), whereby the top ( ) has a radially extending inner collar ( ) in the region of mounting on the other support part ( ). The inner collar overlaps radially a widening of diameter ( ) of the flexible element ( ) located in the interior of the top ( ).
