Abstract
A seating load detecting device in which a lower arm for supporting a seat cushion and a seat back is coupled with an upper rail by a front bracket and a rear bracket. A distortion gage is attached to the bracket. The bracket comprises a curved portion of a U-shape or V-shape. The lower arm and the upper rail are coupled to each other with the direction orthogonal to two opposing legs of the curved portion being vertical. The distortion gage has a total of four distortion detecting elements G11 to G22 distributed in a matrix distribution, two attached in the front and back directional plane of the legs and two attached in the width directional plane of the legs. Due to the Wheatstone bridge connection line of these elements, high gain of a seating load detection voltage e with respect to the amount in change of the vertical load Fv can be obtained.
