A load detecting vehicle seat assembly includes a discrete strain gage mounting plate having a specified flatness to produce desired strain gage performance. The strain gage mounting plate is disposed between a strain gage and a vehicle seat component, such as a cushion frame, so that vehicle seat loading is transferred to the strain gage through the mounting plate. The strain gage may be mounted with a central portion secured to a lower vehicle seat component and outward portions secured to an upper vehicle seat component such that only the outward portions of the strain gage contact the strain gage mounting plate, which has a controlled flatness tolerance to produce desired strain gage performance.

A front seat assembly having a seat bottom assembly and a seat back pivotally attached to the seat bottom assembly. The seat bottom assembly includes a pair of fixed rails extending fore and aft and being laterally spaced across a vehicle from one another. Brackets are attached to the fixed rails for attachment to the vehicle. A slide rail is supported by each of the fixed rails for fore and aft movement relative to the fixed rails. Front and rear cross beams interconnect the slide rails for supporting a number of components. A support sheet, having a pair of openings, extends between and is supported by the cross beams. A seat pan, having a front section and a rear section, is disposed above the support sheet for supporting an occupant. A pair of projections are pivotally connected to and extend from the seat pan for sliding engagement within the pair of openings in the support sheet. The projections are disposed between the front and rear sections of the seat pan for allowing the seat pan to pivot about the projections relative to the support sheet. In the embodiment shown, front and rear bladders are utilized between the support sheet and the front and rear sections of the seat pan for raising either or both of the front and rear sections.
