Abstract
Abstract Locking device for a safety belt having a belt lock into which a plug-in tongue can be inserted and be locked by at least one locking latch. The locking latch can be moved by a manual pressure element transversely to the plug-in guide from the locked position into the open position. A spring-activated sliding ejector is disposed within the plug-in guide. A stop which can be moved into the slide path of the ejector acts in conjunction with the pressure element. The stop blocks the ejector in a position a short distance from contact with the locked plug-in tongue. The ejector is released by moving the pressure element into the opening position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
Locking device for a safety belt comprising a belt lock having two spaced plates defining an insertion path, a plug-in tongue attached to a belt for insertion in the insertion path, a latch movable transversely to the direction of the insertion of the plug-in tongue to detent the inserted tongue, a pressure element movable manually against the force of a spring to move the latch transversely out of the detent position, a spring-activated sliding ejector disposed in the insertion path ahead of the tongue, a stop connected with the pressure element to halt the ejector from contacting the tongue when in the detent position, said stop movable with the pressure element and concurrently moves away from blocking said ejector when said pressure element moves said latch out of the detent position.
Claim 2
Dependent Claim
131 words
Locking device for a safety belt comprising a belt lock having two spaced plates defining an insertion path, a plug-in tongue attached to a belt for insertion in the insertion path, a latch movable transversely to the direction of the insertion of the plug-in tongue to detent the inserted tongue, a pressure element movable manually against the force of a spring to move the latch transversely out of the detent position, a spring-activated sliding ejector disposed in the insertion path ahead of the tongue, a stop connected with the pressure element to halt the ejector from contacting the tongue when in the detent position, said stop movable with the pressure element and concurrently moves away from blocking said ejector when said pressure element moves said latch out of the detent position.
Claim 3
Dependent Claim
16 words
Locking device according to claim 1, wherein the stop is a projection of the pressure element.
Claim 4
Dependent Claim
29 words
Locking device according to claim 2, wherein the stop together with the pressure element are movable transversely to the slide path of the plug-in tongue and of the ejector.
Claim 5
Dependent Claim
46 words
Locking device according to claim 3, wherein said stop has a support surface for contact with said ejector, which surface is slanted with respect to the direction of its motion, whereby the pressure element is urged into the non-operative position by the force of the ejector.
Claim 6
Dependent Claim
41 words
Locking device according to claim 2 or claim 3 or claim 4, wherein the locking path between the stop and the ejector is of sufficient distance to prevent release of the ejector until the locking latch is in the opening position.
