US Patent 7900736 Vehicular seats with fluid-containing weight sensing system
All edits
System and method for measuring the weight of an occupant in a vehicle seat and for controlling a safety restraint system responsive thereto includes at least one fluid-containing structure arranged mounted within or beneath an upper surface of a bottom portion of the seat and supported by a base of the seat and at least one pressure sensor operatively coupled to the fluid-containing structure(s) for generating a signal responsive to pressure of the fluid within the fluid-containing structure(s) caused by pressure applied to the upper surface of the seat by the occupant. A processor is coupled to the pressure sensor(s) and provides an indication of the weight of the occupant from the signal and generates a control signal for controlling the safety restraint system based on the weight. The fluid-containing structure may be a bladder arranged in the bottom of the seat and/or include a plurality of interconnected chambers.
