| Zusammenfassung: | An apparatus (
210
) includes seat belt webbing (
12
), a parallelogram linkage (
220
), a sensor lever (
370
), and a sensor (
379
). The seat belt webbing (
12
) helps to protect the occupant (
14
) of the vehicle (
18
). The parallelogram linkage (
220
) includes a first beam (
352
) and a second beam (
362
) parallel to the first beam (
352
). The first and second beams (
352, 362
) each bend in response to at least part of a load applied by the seat belt webbing (
12
). The sensor lever (
370
) is interposed between the first and second beams (
352
). The sensor lever (
370
) has a connection with the first and second beams (
352
). The connection causes the sensor lever (
370
) to deflect upon bending of the first and second beams (
352
). The sensor (
379
) senses the deflection of the sensor lever (
370
) and provides an output signal indicative of the amount bending of the first and second beams (
352, 362
). |
