Detector device for detecting the locking state of a seat belt lock, insert, and seat belt lock equipped with a detector device

摘要

A detector device for detecting the locking state of a seat belt lock, such as for an automobile restraint system, is disclosed, which has a swivel lever that is designed like a strap and that is hinged to a switch housing via a swivel axis (A) that is arranged eccentrically and that has at least one operating arm projecting from the swivel axis (A), which arm extends above the switch housing and can move into a second end position by interaction with a component of a locking mechanism of the seat belt lock that can move in translation against a return force from a first end position, in which its at least one operating arm extends above the switch housing. The detector device has a sensor device for detecting the change in position of a section of the swivel lever that can swivel from the starting position into its laterally and vertically changed end position.

主权项

1. Detector device for detecting a locking state of a seat belt lock, comprising:
a swivel lever configured as a strap and hinged to a switch housing via a swivel axis (A) that is arranged eccentrically and that has at least one operating arm projecting from the swivel axis (A), which arm extends above the switch housing and is movable into a second end position by interaction with a component of a locking mechanism of the seat belt lock that is movable in translation against a return force from a first end position, in which the at least one operating arm extends above the switch housing, whereby a position of a cam, facing away from the at least one operating arm will change its position vertically and laterally relative to a starting position; and a sensor device for detecting a change in position of the cam, from the starting position into its laterally and vertically changed end position, and for transforming said detected position change into an electromagnetic signal, that is available at an output port of said sensor device.
