Seat belt force sensor

摘要

A seat belt force-sensing mechanism (20) has a housing with first (22) and second (24) housing members. A slidable plate (26) is positioned between plate portions of the first and second housing members. Various spacers are located between the first housing member and the sliding plate to space and stabilize the plate relative to the first and second housing members. A magnetic sensor (230) is mounted between the first and the second housing members. A magnet (252) is moveable with the sliding member in response to forces applied to the first and second housing members and to the sliding plate. One end of the spring assembly (250) engages the sliding plate and another end of the spring assembly engages the housing while biasing the sliding plate within the housing. An adjustment mechanism (350) assists in the calibration of the bias force acting between the housing members and the sliding plate.
