Force measuring element for measuring the weight of a person on a motor vehicle seat

摘要

Force measuring element for measuring the weight of a person on a motor vehicle seat, comprising between the motor vehicle seat (13) and the seat holder (11) of the motor vehicle and a sleeve which can be fastened on the motor vehicle seat (2), in which a longitudinal force measuring body (3), on the strain gauge (18, 19, 20, 21) are arranged, is horizontally arranged, at its one end with the sleeve (2) and firmly connected at its other end with the seat holder (11) is connectable, wherein the sleeve the force measuring body (3), including the strain gauges (18, 19, 20, 21) to a ring disposed on the force measuring body (9) covers, wherein the between the ring (9) and the sleeve (2) resulting annular gap (14) limits the maximum weight carrying. In this case, the force measuring body (3) transversely to its longitudinal extension of a horizontal bore (15) on. For measuring the bending stress, the strain gauges (18, 19, 20, 21) to the through the bore (15) formed on both sides of the same bending beam (16, 17) is arranged.
