OCCUPANT WEIGHING DEVICE OF VEHICLE SEAT, AND MOUNTING STRUCTURE OF LOAD SENSOR

摘要

PROBLEM TO BE SOLVED: To provide an occupant weighing device of a vehicle seat capable of suppressing the generation of an initial load, and provide a mounting structure of load sensors. 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. Load sensors 21 and 23 are fixed on an upper surface of the upper rail 5, and load sensors 22 and 24 are fixed on a front part of the upper rail 6. A rectangle frame 40 is mounted on the load sensors 21 to 24. A rod 21c of the load sensor 21 passes upward through a web 41a, and is inserted in a through hole formed in a center part of a plate spring 64. The plate spring 64 is bent in an angular shape so that the center part of the plate spring 64 is separated from the web 41a. A nut 66 is screwed to the rod 21c from an upper part of the plate spring 64. Both skirts of the plate spring 64 abut on the web 41a in a state of the plate spring 64 fastened by the nut 66.
