Abstract: Structure of vehicle seat with lifter wherein the lifter, including lifter link elements, is operatively provided between a first element provided to vehicle seat and a second element adapted for connection with a floor of vehicle. The first and second elements are each of double wall structure having two spaced-apart walls. The lifter link elements are rotatably connected with the first and second elements by first and second pins, such that one portion of the lifter link elements is in a slidable contact with the two spaced-apart walls of first element, with the first pins passing through that one portion of lifter link elements and those two walls of first element, while another portion of the lifter link elements is in a slidable contact with the two spaced-apart walls of second element, with the second pins passing through that another portion of lifter link elements and those two walls of the second element.

Abstract: A load detection structure in a vehicle seat having a slide rail device provided therewith, which basically comprises a generally oblong block member having a rigid yet resiliently deformable property and a strain gauge attached tight thereon. The block member extends along a part of the slide rail device, such that the deflectable portion thereof is operatively connected with the vehicle seat, while the base portion thereof is fixedly connected with that part of the slide rail device. Hence, a load applied to the seat causes deflection of the deflectable portion of block member, in response to which, the strain gauge detects an amount of such deflection and determines a weight of occupant on the seat.
