Title: LOAD DETECTION SENSOR UNIT
Abstract:
This load detection sensor unit (1) is disposed under a seat cushion, and comprises: a load detection sensor (5) which detects a load; a pedestal (2) which has a mounting surface (21S) on which the load detection sensor (5) is mounted, and which is disposed between at least spring portions facing each other among a plurality of S-springs (100) that are arranged side by side in such a manner as to extend across the opening of the frame; and a cushioning member (3) which is disposed in at least a portion between each of the spring portions and the pedestal (2). The pedestal (2) has a pair of hook portions (22) which are hooked on the spring portions facing each other. The hook portions (22) extend so as to cover the top (100C) of the spring portions and outside portions (100B) on the reverse side from the side on which the spring portions face each other. The cushioning member (3) has a hardness that is smaller than that of the pedestal (2), and is disposed between the hook portion (22) and the spring portion.
