Device for sensing and restraining object, especially vehicle seat occupant, has sensor for weight of object in seat, seat belt tension sensor and controller determining computed object weight

摘要

The device has seat belt webbing (12) for restraining an object (14) in a vehicle seat (16), a sensor (50) for the weight of the object in the seat, a seat belt tension sensor (60) and a controller (44) for determining a computed weight of the object as a function of both the detected weight and the belt tension. The error in the computed weight is less than in the detected weight.
