力センサ
Document Type and Number:
Japanese Patent JP2005531758
Kind Code:
A
Abstract:
A force sensor, in particular for detecting the forces on a vehicle seat, includes a force measurement cell ( 1 ) that has a Hall element. The force measurement cell ( 1 ) includes at least one bending bar ( 2, 3 ), which from the exertion of force to be detected exeris an influence on the magnetic field in the region of a magnetic-field-sensitive sensor element ( 6 ) of the measurement cell ( 1 ). The sensing is done with a Hall element ( 6 ), held on the at least one bending bar ( 2, 3 ), which element, under the force exerted on the bending bar ( 2, 3 ), can be deflected in the field of a relatively stationary permanent magnet ( 4 ), and a magnetic diagnosis field in the region of the Hall element ( 6 ) can be generated whose field lines are located in the plane of the sensor element without influencing the measurement field.
