Abstract: A belt lock for a seat belt system includes a locking mechanism arranged in a belt lock housing formed from two housing shells for an inserted belt tongue. The locking mechanism has an axially movable component that changes its location from a first end position into a second end position when the locking mechanism is actuated. The locking mechanism is also equipped with a switch arrangement that has at least one fixed contact part and one switching contact part that can move relative to it and on which, in an end position of the component that changes its location, the component acts. The switching contact part is configured as a clamp-shaped elastic sheet part with two axially running side braces that are provided with knee-like bends that, in an end position of the axially movable component, are mechanically exposed to pressure by the component.

A fixing mechanism pretensions the switching contact part prior to installation such that the at least one extension does not project beyond the outside surface of the mounting plate. The fixing mechanism releases the switching contact part tension when the switch assembly is installed and in the operating position.

Abstract: 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.

Abstract: An exemplary circuit arrangement for a belt lock of a passenger restraint system in motor vehicles includes one contact sheet pair having a fixed contact sheet and an elastic contact sheet which interacts with a slide. The slide is a component of a locking mechanism located in a belt lock housing for an inserted belt tongue, and is pushed in a displacement channel from a first end position into a second end position when the locking mechanism is actuated. The contact sheet pair is in a housing part which borders the displacement channel. A part, which projects from the elastic contact sheet through a housing wall opening into the displacement channel, is exposed to the action of the slide to open or close an electrical contact to the contact sheet. The circuit includes means for preventing abraded matter from traveling into the contact region of the contact sheet pair.

Abstract: A switch arrangement is disclosed that can, for example, be used for installation in a belt lock of a seat belt system, and which includes a fixed contact part and an elastic switching contact part, which are located on a mounting plate. The switching contact part can have at least one extension that projects over the outside surface of the mounting plate in the operating position. When the switching contact part is exposed to pressure in the direction of the mounting plate, an electrically conductive contact between the switching contact part and the fixed contact part can be interrupted or established. A fixing device can be included via which the switching contact part is pretensioned in such a way that the extension does not project over the outer surface of the mounting plate. The fixing device can be detached when the switch arrangement is being mounted with release of the elastic switching contact part.

Abstract: A belt lock for a seat belt that has a locking mechanism that is arranged in a belt lock housing. The locking mechanism includes a component that changes location from a first end position into a second end position when the locking mechanism is actuated, and in doing so interacts with a status detector. The status detector is designed as an electrical switching system. The component that changes location is a mandrel that can be moved axially when the locking mechanism is actuated and that is provided with an electrically conductive contact region and forms a component of the electrical switching system.

Abstract: A seat belt buckle for seat belts has a housing, an opening for inserting a seat belt tongue, a locking device for locking the seat belt tongue, and a release device for releasing the seat belt tongue from the lock. A sensor device electrically senses whether the seat belt tongue is locked, wherein the sensor device has a switch arrangement which can be activated by the seat belt tongue. The switch arrangement has an electrically conductive snap-action plate that can be moved between a first switched position and a second switched position. A mechanical activation device transmits a force exerted on the seat belt tongue during the insertion of the seat belt tongue onto the snap-action plate in order to move the snap-action plate from the first switched position into the second switched position. As a result, an electrical contact element is closed or opened.

Abstract: [Summary] [Problem] To provide a buckle switch and buckle device wherein a first switch section and a second switch section are unitized to provide improved assembling workability and increased production efficiency. [Means for Solving Problem] As a tongue plate is inserted to a buckle body to move a slider, a pressing segment 23b of the slider rotates a leaf spring 46 in a direction a and, hence, a depressible portion 44c is depressed to cause a movable member 44 to move in a direction X2. At this time, a stationary contact 71a moves into and is pinched by pinch members 53 of a movable contact 50 disposed on the movable member 44, rendering the switch section SW1 to assume a conductive state. Concurrently, since a magnet M2 is placed in opposition to a magnetic detecting element 61, a second switch section SW2 is switched over. By unitizing the first and second switch sections, assembling workability of a buckle switch 40 to the buckle body can be improved, enabling an increase in production efficiency.

Abstract: The invention relates to an actuator, which is used in a belt latch mechanism of restraint systems in motor vehicles and which indicates the proper locking of the tongue of the safety belt when the tongue is inserted into the belt latch mechanism. The actuator is provided in the form of a double-contact actuator, whereby the contact steel plates are arranged inside a contact space that is closed at the top, and the contact can be actuated by a slide by moving this slide into a channel situated to the side of the inner space of the housing.

Abstract: A sensor for detecting a rupture or length change in a belt. The sensor has a movable transmission element operatively connected to the belt, that acts on an electrical switch having a contact system in the event of a length change or rupture of the belt. The contact system comprises a switching contact with a contact surface arranged on a first end, and an associated fixed contact. The transmission element acts on the second end of the leaf spring. A limb extends approximately from the first end of the leaf spring in the direction of the second end, and a further limb extends from the second end of the leaf spring in the direction of the first end. The free ends of the two limbs are clamped offset from one another on a carrier part of the switch, such that the switching contact switches over in a bistable manner.
