Abstract:
Apparatus for suppressing the operation of a restraint system when a child's seat is mounted and strapped on a car seat in a vehicle, comprising:a seat belt having a first end arranged to be connected to a child seat to anchor same to a vehicle, and a looped second end;a belt anchoring structure attached to the vehicle;a transducer connected between the seat belt and the belt anchoring structure, comprising:a transducer plate connected to the belt anchoring structure and having opening means for connecting the looped end of the seat belt, the transducer plate being elastically deformable in response to a tensile load applied by the seat belt to the transducer plate;a rigid structural plate connected to the belt anchoring structure and having opening means for coupling to the looped end of the seat belt and being relatively non-stretchable in response to a tensile load applied by the seat belt;a strain gage mounted on the transducer plate to transmit an electrical signal when the transducer plate has been deformed by the seat belt; andthe transducer plate being disposed to transfer a tensile seat belt load to the structural plate when the transducer plate has been elongated a predetermined amount.
