Abstract
A load detection structure in a vehicle seat with a support leg member, which includes a block member of rigid yet resilient recovery property and a strain gauge attached thereon. The block member is interposed between the seat and support leg member, such that a securing portion thereof is secured to the seat, whereas a pivotal end portion thereof is rotatably pivoted to the support leg member. The securing portion is displaced in a vertical direction due to a vertical load applied to the seat, while the pivotal end portion is rotated, so as to cause deflection in the block member, which is detected by the strain gauge. It may be so arranged that the block member is rotatable about its central axis, thereby being prevented against twist due to a lateral load applied to the seat. An auxiliary linkage is provided to insure preventing such twist of block member.
