Abstract: A weight-sensing assembly for supporting an automotive seat cushion frame atop a track assembly includes a pair of coupling members that are secured to the seat cushion frame. A set of mounting locations on each coupling member, preferably separated by an elongate portion of the coupling member of generally uniform cross-section, are secured to a respective end of a strain gage sensor's elongate sensing beam. The other end of each sensing beam is secured to a respective mounting location defined on the upper rails of a seat track assembly. The elongate portion of the coupling member, and respective portions of the upper rails separating the mounting locations thereon, are characterized by a flexural stiffness, in a bending plane that includes a longitudinal axis of the sensing beam of at least one sensor assembly, that is at least three times greater than the flexural stiffness of each sensor's sensing beam.
