Abstract:
A system for measuring the weight of an occupant in a vehicle seat and for controlling a safety restraint system responsive thereto, comprising:a. a bladder mounted beneath the cushion of the seat and supported by the base of the seat, whereby said bladder is constructed from a flexible material; b. a fluid contained by said bladder, whereby for substantially no external load applied to said fluid filled bladder the volume of said fluid in said fluid filled bladder is less that the capacity of said fluid filled bladder; c. a pressure sensor operably coupled to said bladder for generating a signal responsive to the pressure of said fluid within said bladder; and d. a signal processor for measuring the weight of the occupant from said signal for generating a control signal for controlling the safety restraint system responsive to said weight measurement.
