A sensor device includes a base element extending in an axial direction and a first magneto elastic active region representing a first longitudinal section of a surface of the base element. The first longitudinal section extends in the axial direction and is magnetized in a first circumferential direction. The sensor device further comprises a first magnetic field sensor overlapping with the first longitudinal section, and a second magnetic field sensor disposed at a distance with respect to the first magnetic field sensor along the axial direction and overlapping with the first longitudinal section.

A sensor system for detecting an adjustment position of a vehicle seat, the sensor system having a Hall sensor and a first preloaded magnet, and it is free of flux concentrators and shielding sheets. The Hall sensor and the first preloaded magnet are arranged along a longitudinal extension of the upper rail that is movable lengthwise such that during adjustment of the upper rail, passage of a free longitudinal end of the stationary lower rail will be monitored and result in a change of an output signal of the Hall sensor.

Sensor system for detecting the adjustment position of a vehicle seat

A sensor system is disclosed for detecting positions of two at least partially ferritic components that can move relative to one another, namely a stationary component and a component that can move lengthwise along a longitudinal extension of the stationary component, which are mounted right next to one another. The sensor system can include a Hall sensor and a preloaded magnet, eliminating flux concentrators and shielding sheets. The Hall sensor and the preloaded magnet are arranged along a longitudinal extension of the movable component such that relative movement of the two components is detected by monitoring a free longitudinal end of the stationary component.

A seat belt lock with a Hall sensor for detection of a locking state of a seat belt lock having a metal seat belt lock frame arranged in a housing. The seat belt lock frame has an upper part and a lower part, connected to a define slit-like channel. A spring-loaded locking device for an inserted seat belt latch is mounted on the seat belt lock frame. A spring-loaded ejector for the inserted seat belt latch is arranged in the channel. The Hall sensor interacts with a permanent-magnetic component, whose distance relative to the Hall sensor is changeable based on translatory movement of the ejector in the case of actuation of the locking mechanism. The Hall sensor is arranged on or in the seat belt lock frame and is covered by a metal shielding element, which extends essentially parallel to the seat belt lock frame and forms a flow concentrator.

A belt lock is provided with a state sensor for detection of the locking state of a safety belt system, for example in an motor vehicle. The belt lock includes a locking mechanism which is located in a belt lock housing, which is formed from an upper shell and a lower shell, for an inserted belt tongue which has a component which changes its location from a first end position into a second end position when the locking mechanism is actuated. Actuation of the locking mechanism can be monitored by the state sensor. The state sensor is made as an electronic sensor element which is located in the lower shell.

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.

A switch is provided for a belt lock of a safety belt system, for example, in a motor vehicle. The switch includes a switch housing which has a contact space in which two contact sheets interact, and a channel which borders the contact space and in which a slide can be moved. A section of the contact sheet made as a contact spring projects into the channel, as a free end section which projects beyond one contact region of the contact sheets. A connecting opening is located in a position of use of the switch above the contact region of the two contact sheets.
