OCCUPANT WEIGHT MEASUREMENT DEVICE FOR VEHICLE SEAT AND INSTALLATION STRUCTURE FOR LOAD SENSOR

摘要

A lower rail 3 is fixed to a vehicle floor, and an upper rail 4 is movable in a rear and front direction with respect to the lower rail 3. A load sensor 21 is fixed to an upper surface of the upper rail 4. A rectangular frame 30 is attached onto the load sensor 21, a rod 21c of the load sensor 21 sequentially penetrates a web 31a of the rectangular frame 30 and a spring holder 45 upward, and a coil spring 44 is wound around the rod 21c. A nut 46 is screwed to the rod 21c, and the nut 46 tightens a bottom of a cup portion 45c of the spring holder 45. The coil spring 44 is sandwiched between a flange 45a of the spring holder 45 and the web 31a and is compressed by tightening the nut 46.
