Embodiment Construction

[0015] The switch, shown in open form, contains a switch housing 1 which is closed by means of a cover at the top of the connection space 5 , which is not shown in the figure.

[0016] The switch has a housing interior 2a enclosed in the contact region. A connection space 5 is provided in the lower region of the switch. The fixed contact piece 6 and the contact spring 7 terminate in this connection space 5 . The contact spring 7 can be connected to the connection line 10 here. The connection space 5 is designed to be open on both sides.

[0017] The contact spring 7 has an arcuate region 9 and a hammer region 8 . The arc-shaped region 9 passes through the fixed contact piece 6 in the region of the double contact tongue and protrudes into the groove 3 . The contact spring 7 is actuated and the contacts are separated by the slide 4 which moves downward due to the insertion of the belt tongue into the belt lock.

[0018] The two sides of the hammer-shaped region 8 of the con...

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.

Description

technical field [0001] The invention relates to a switch which can be used in a seat belt locking device of a retraction system of a motor vehicle and which indicates the sequential locking of a seat belt tongue inserted in the seat belt locking device. Background technique [0002] Known from DE 43 38 485 A1 is a seat belt locking device with a microswitch provided for a fail-safe-response device, wherein the microswitch is connected to two mutually independent parts in the locking procedure of the locking device in such a way that The micro switch is only closed when the above two parts are in the functional position of the locking position at the same time, and the position is arranged for triggering other functional elements of the safety device. [0003] A switch for use in a seat belt locking device is also known from Eduard Hartmann GmbH. This switch is a double-contact switch whose contact springs or contact tongues bear against each other at the contact points in t...
