OCCUPANT WEIGHING DEVICE FOR VEHICLE SEAT

摘要

PROBLEM TO BE SOLVED: To provide an occupant weighing device for a vehicle seat capable of suppressing the generation of an initial load. SOLUTION: Lower rails 3 and 4 are fixed on a floor of a vehicle, and upper rails 5 and 6 are longitudinally movable on the lower rails 3 and 4. A load sensor 21 is fixed on an upper surface of a front part of the upper rail 5, and a load sensor 23 is fixed on an upper surface of a rear part thereof. A load sensor 22 is fixed on an upper surface of a front part of the upper rail 6, and a load sensor 24 is fixed on an upper surface of a rear part thereof. A rectangular frame 40 is mounted on the load sensors 21 to 24. While the right front load sensor 21 and the left rear load sensor 24 are fixed to the rectangular frame 40 in longitudinal and lateral directions, the right rear load sensor 23 and the left front load sensor 22 are in the idle state in the longitudinal and lateral directions with regard to the rectangular frame 40.
