WEIGHT SENSOR FOR CONTROLLING AIRBAG DEPLOYMENT

摘要

An arrangement is provided for controlling activation of an airbag system (10, 12, 14) in a vehicle. The vehicle has a passenger seat (26) comprising a seat frame (32) and a string network (24) attached to the seat frame for supporting a weight of an occupant in the passenger seat. The arrangement comprises a sensor (22) operatively coupled to a portion of the string network for sensing a tensile load exerted on the string network created by the weight of the occupant in the passenger seat and producing an output signal representing the tensile load. A processing unit (20) is coupled to the output of the sensor for producing a control signal for controlling activation of the airbag system when the signal representing tensile load reaches a pretermined threshold value.
