1. A force sensor for determination of forces on a vehicle seat, comprising a support element arranged between an upper frame and a lower frame;
- a force measuring cell arranged in said support element, said upper frame being a stationary part of a rail for a longitudinal or vertical adjustment, said measuring cell being located at a location selected from the group consisting of inside said rail and on said rail, said measuring cell having at least two bending beams which, in response to a force action to be determined influence a magnetic field in a region of a magnetic-field-sensitive sensor element of said measuring cell, at least one of said bending beams having one end which is held in a pot and another end mounted on a member selected from the group consisting of said rail and said lower frame, and said pot being mounted through a swivel nut and a mounted angle on said lower frame while the other end of the bending beams is mounted by a further mounting angle on a lower side or a side wall of said rail.
