摘要： A system for measuring the weight of a seat occupant is used to control airbag deployment. The system includes a seat bottom that receives a vertical seat occupant weight force. The seat is divided into four quadrants, a front right quadrant, a left front quadrant, a left rear quadrant, and a right rear quadrant. Each quadrant includes a sensor that generates a weight signal corresponding in magnitude to the seat occupant weight in the respective quadrant. Each weight signal is comprised of a vertical force component and an error component induced by braking or deceleration forces acting on the seat bottom in a non-vertical direction. The sensors are orientated within their respective quadrants such that two sensors generate a positive error reading and two sensors generate a negative error reading. When the weight signals from each quadrant are added together to determine the total seat occupant weight, the error is eliminated as the positive and negative error components cancel each other out. The seat occupant weight is determined by adding the vertical force components from each of the weight signals together.

摘要： A system for measuring seatbelt forces is used to control deployment of vehicle airbags. The system includes a seatbelt anchor assembly having a bracket mounted to a vehicle structure adjacent to a vehicle seat. A seatbelt mechanism has a belt portion that is looped through the bracket. The seatbelt is used to secure passengers or an infant car seat to the vehicle seat. A sensor is engaged with the anchor assembly and is used to measure the magnitude of forces exerted on the seatbelt by the passenger or car seat. The sensor generates a signal representative of the seatbelt forces, which is used to control deployment of the airbag.
