ABSTRACT:
A force measuring device for seat weight determination in a motor vehicle includes a taking up element which has at least two bearing points. The device further includes a mechanism forming a first recess in the taking up element in a region between at least two bearing points and a rod-shaped element which extends in the longitudinal axis of the taking up element and is not loaded by bending forces. The rod-shaped element has a free end which deviates from the longitudinal axis of the taking up element when a force to be measured acts on the taking up element, and a measuring unit with a magnet and a magnetic field-sensitive sensor The magnet and the magnetic field-sensitive sensor are arranged immovably relative to one another so that the distance from the magnet to a ferromagnetic material changes under loading with the force.
