Abstract
Abstract Belt lock for a safety belt with a spring-operated locking catch with hooked part engaging a plug-in tongue. A hand-operated member has a locking part in fixed connection. The locking part is disposed in the path of motion of the hooked part preventing release of the tongue unless the member is pressed by hand to move the locking part out of the path of motion. The locking part is movable along the plug-in axis; and the locking part in the closed position couples with the locking catch.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
186 words
Belt lock for a safety belt with a plug-in opening for the insertion of a plug-in tongue fastened to the belt, a spring-operated locking catch with a hooked part in the belt lock engaging the plug-in tongue when inserted in the plug-in opening of the belt lock, a hand-operated member movable against the force of a spring for operating the locking catch to detach the tongue from the belt lock, a locking part in fixed connection with the hand-operated member, wherein in the locked position of the belt lock, the locking part is disposed in the path of motion of the hooked part preventing the latter from disengaging the tongue, and wherein the locking part presses the plug-in tongue by spring action against the hooked part of the locking catch and wherein when the hand-operated member is moved against the force of said spring, the locking part in fixed connection with the hand-operated member is also moved out of the path of motion of the hooked part permitting the hooked part to become disengaged from the tongue, and the tongue to detach from the belt lock.
Claim 2
Dependent Claim
186 words
Belt lock for a safety belt with a plug-in opening for the insertion of a plug-in tongue fastened to the belt, a spring-operated locking catch with a hooked part in the belt lock engaging the plug-in tongue when inserted in the plug-in opening of the belt lock, a hand-operated member movable against the force of a spring for operating the locking catch to detach the tongue from the belt lock, a locking part in fixed connection with the hand-operated member, wherein in the locked position of the belt lock, the locking part is disposed in the path of motion of the hooked part preventing the latter from disengaging the tongue, and wherein the locking part presses the plug-in tongue by spring action against the hooked part of the locking catch and wherein when the hand-operated member is moved against the force of said spring, the locking part in fixed connection with the hand-operated member is also moved out of the path of motion of the hooked part permitting the hooked part to become disengaged from the tongue, and the tongue to detach from the belt lock.
Claim 3
Dependent Claim
77 words
Belt lock according to claim 1, wherein two locking catches which are arranged symmetrically on both sides of the plug-in axis, are hingeably supported, and tensioned by spring action in the direction of the opened position, and wherein the locking part is movable along the plug-in axis and is by spring action tensioned in a direction opposite to insertion path of the plug-in tongue, and said locking part in the locked position couples with the locking catches.
Claim 4
Dependent Claim
66 words
Belt lock according to claim 1, wherein a locking catch is hingeably supported, and tensioned by spring action in the direction of the opened position, and wherein the locking part is movable along the plug-in axis, and is by spring action tensioned in a direction opposite to insertion path of the plug-in tongue, and said locking part in the locked position couples with the locking catch.
Claim 5
Dependent Claim
41 words

Claim 7
Dependent Claim
61 words
Belt lock according to claim 4, wherein the locking catches, together with the hooked parts have pressure parts and form claws which enclose the plug-in tongue, and said pressure parts work together with a front-side pressure surface of the plug-in tongue for moving the locking catches into the lock position, respectively for throwing the plug-in tongue out of the lock position.
Claim 8
Dependent Claim
57 words
Belt lock according to claim 5, wherein the locking part has stop edges disposed at both sides of a pressure nose which is positioned on the plug-in axis and wherein in the opened position of the lock, the locking part is banked against associated contact edges of the locking catch by said stop edges by spring action.
Claim 9
Dependent Claim
57 words
Belt lock according to claim 6, wherein the locking part has stop edges disposed at both sides of a pressure nose which is positioned on the plug-in axis and wherein in the opened position of the lock, the locking part is banked against associated contact edges of the locking catch by said stop edges by spring action.
Claim 10
Dependent Claim
44 words
Belt lock according to claim 1, wherein the locking catches and the locking part are disposed in a U-shaped bracket, which is made as a one-piece stamped part, and said bracket is provided at its front-side with a plug-in opening for the plug-in tongue.
