    摘要： An improved occupant detection system and method includes a fluid-filled polymeric seat cushion bladder defining multiple fluid-filled chambers corresponding to different areas of the seat cushion, with no fluid flow between such chambers. Fluid pressures in the various individual chambers are detected and processed to develop a weight estimation that is compensated for occupant position. The chambers are configured to detect occupant weight in at least forward, rearward, inboard and outboard regions of the bottom seat cushion. When the detected pressures are unevenly distributed and the pressure in the forward, rearward, inboard or outboard regions of the seat exceeds the average pressure by at least a predetermined amount, a composite pressure indicative of occupant weight is adjusted in a direction to bias the suppression status in favor of allowing restraint deployment, unless the occupant is forwardly positioned on a seat that is also forwardly positioned.

    摘要： An improved vehicle seat occupant weight estimation method detects weight applied to both the seat cushion and the floor forward of the seat, and increases the measured seat weight of the occupant to account for occupant weight off-loaded to the floor. Fluid-filled bladders or other sensors are arranged to detect occupant seat weight and the weight applied to the vehicle floor forward of the seat. Upon opening of a vehicle door or an off-to-on transition of the vehicle ignition switch, the seat and floor weight sensors are monitored to detect the presence of an occupant. When the seat becomes occupied, or whenever there is a large change in the measured seat weight, the seat and floor weight are recorded, the occupant weight is estimated according to the recorded seat weight, and the inflatable restraints are allowed or suppressed based on the estimated occupant weight. When a sustained occupant weight shift is detected, the estimated occupant weight is increased in proportion to the amount of weight shifting, but is limited to a maximum value based on the detected floor and seat weights.

    摘要： In a vehicle seat occupant detection system, a transponder in a seat cushion is responsive to an activating signal to generate an electromagnetic signal containing unique seat identification data. An occupant detection system module senses a seat characteristic and derives therefrom an occupant detection signal. The module further generates the transponder activating signal and receives and processes the electromagnetic signal to derive the contained seat identification data. The module determines if there is seat identification data in a dedicated memory location in rewritable, non-volatile memory and, if there is, compares it to the seat identification data from the electromagnetic signal. If they do not match, the derivation of a valid occupant detection signal is prevented. If there is no seat identification data in the dedicated memory location, the module causes the seat identification data from the electromagnetic signal to be copied to the dedicated memory location if it remains unchanged for a predetermined number of transponder activations so as to allow authorized matching of a seat cushion and module.

    摘要： A child seat anchor apparatus includes at least one sensor for measuring tension exerted on a system including a pair of anchor brackets disposed between the bottom and back cushions of a vehicle seat. In a first mechanization, the anchor brackets are directly coupled to individual sensors mounted on an anchor frame that is bolted to the seat frame. In a second mechanization, the anchor brackets are fastened to an anchor frame that is pivotably mounted on the seat frame, and the anchor frame is additionally coupled to the seat frame through a single sensor responsive to the tension exerted on the anchor frame by the anchor brackets.

    摘要： A child restraint system for transporting a child within an automotive vehicle includes a weight sensor for determining the weight of the child and compares the child's weight to a recommended weight range. The weight sensor is disposed within a cushion that lines a shell and provides an electrical signal to a control unit. The control unit processes the electrical signal and provides an alert signal when the weight is not within the recommended range. Also, the child restraint system may include a second sensor for sensing a condition that depends upon the child's weight such as directional orientation or angular orientation of the child restraint system, or location or tension of a vehicle seat belt or tether that secures the child restraint system within the vehicle, or the location or tension of a harness for restraining the child occupant within the child restraint system.
