Abstract:
A vehicle seat structure, comprising:a seat defining a surface adapted to contact an occupying item; and a weight sensor arrangement arranged in connection with said seat for providing an indication of the weight applied by the occupying item to the surface of said seat, said weight sensor arrangement including conductive members spaced apart from one another such that a capacitance develops between opposed ones of said conductive members upon incorporation of said conductive members in an electrical circuit, the capacitance being based on the space between said conductive members which varies in relation to the weight applied by the occupying item to the surface of said seat, said weight sensor arrangement further including a pair of non-metallic substrates and a layer of a compressible material situated between said non-metallic substrates.
