Abstract
Abstract Lock for a safety belt having a belt lock and a plug-in tongue which can be locked in position by a latch movable by a manual pressure element transversely to the plug-in tongue direction to the opening position. The latch is retained by a force, preferably a spring-loaded ejector, in the opening position. When a pulling force exceeding a predetermined value acts on the plug-in tongue, an insertion lock in the belt lock permits withdrawal of the tongue but prevents a renewed insertion of the tongue.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
147 words
Lock for a safety belt comprising a belt lock with spaced plates defining an insertion path, a plug-in tongue for insertion in the insertion path, a latch movable transversely to the insertion path to the locked position in which the latch is interposed in the path of the tongue and to the open position in which the latch does not block passage of the tongue in the insertion path, a manually operated pressure element to move the latch from the locked position to the open position, spring means retaining the latch in the open position when the tongue is withdrawn from the insertion path, and an insertion lock in the belt lock activated by a pulling force on the plug-in tongue exceeding a predetermined value to restrain said spring means to permit withdrawal of the tongue from the insertion path and prevent renewed insertion after such withdrawal.
Claim 2
Dependent Claim
147 words
Lock for a safety belt comprising a belt lock with spaced plates defining an insertion path, a plug-in tongue for insertion in the insertion path, a latch movable transversely to the insertion path to the locked position in which the latch is interposed in the path of the tongue and to the open position in which the latch does not block passage of the tongue in the insertion path, a manually operated pressure element to move the latch from the locked position to the open position, spring means retaining the latch in the open position when the tongue is withdrawn from the insertion path, and an insertion lock in the belt lock activated by a pulling force on the plug-in tongue exceeding a predetermined value to restrain said spring means to permit withdrawal of the tongue from the insertion path and prevent renewed insertion after such withdrawal.
Claim 3
Dependent Claim
47 words
Lock according to claim 1, wherein the belt lock is connected to a fitting by a connecting element, and wherein said pulling force on the plug-in tongue exceeding a predetermined value causes relative motion between the belt lock and the connection element which activates said spring force.
Claim 4
Dependent Claim
13 words
Lock according to claim 1, wherein said spring means is a spring-loaded ejector.
Claim 5
Dependent Claim
13 words
Lock according to claim 2, wherein said spring means is a spring-loaded ejector.
Claim 6
Dependent Claim
58 words
Lock according to claim 2, wherein said insertion lock has a locking member which is connected with the connecting element, and wherein said locking member at a relative motion with respect to the belt lock due to said pulling force exceeding a predetermined value, restrains said spring means to permit withdrawal of the tongue and prevent renewed insertion.
Claim 7
Dependent Claim
58 words
Lock according to claim 4, wherein said insertion lock has a locking member which is connected with the connecting element, and wherein said locking member at a relative motion with respect to the belt lock due to said pulling force exceeding a predetermined value, restrains said spring means to permit withdrawal of the tongue and prevent renewed insertion.
Claim 8
Dependent Claim
26 words
Lock according to claim 5, wherein said locking member moves by said relative motion in the plug-in direction along a curved guide in said insertion lock.
Claim 9
Dependent Claim
16 words
Lock according to claim 7, wherein said locking member moves into the path of the ejector.
Claim 10
Dependent Claim
17 words
Lock according to claim 7, wherein said locking member moves into the path of said pressure element.
Claim 11
Dependent Claim
26 words
Lock according to claim 7, wherein the locking member is designed as a hook-shaped leaf spring which can move into the slide path of the ejector.
Claim 12
Dependent Claim
60 words
Lock according to claim 10, wherein the locking member has a hook-like part, and wherein the hook-like part catches a stop arranged outside of the insertion path when the locking member is in the rest position, and wherein a distance from the stop, is a detention opening for catching the hook-like part of the locking member when it is activated.
Claim 13
Dependent Claim
34 words
Lock according to claim 11, wherein the ejector is constructed in the form of a pressure spring, and wherein the locking member can with its hook-like end hook into a winding of the ejector.
Claim 14
Dependent Claim
50 words
Lock according to claim 1, wherein the latch has a contact-slant surface pointing toward the locking-edge of the tongue, whereby when the latch is only partly moved into the opening position by the pressure element, the tongue pressing against the slant surface completes moving the latch into the opening position.
Claim 15
Dependent Claim
29 words
Lock according to claim 5, wherein the connecting element between the belt lock and the fitting is a rivet, and wherein the locking member is coupled with the rivet.
Claim 16
Dependent Claim
42 words
Lock according to claim 9, wherein the belt lock has a slot-like rivet guide in the direction of belt insertion, in which guide the rivet is retained until a predetermined pulling force occurs, and after exceeding of this force can slide therein.
Claim 17
Dependent Claim
42 words
Lock according to claim 9, wherein the fitting has a slot-like rivet guide in the direction of the belt insertion, in which guide the rivet is retained until a predetermined pulling force occurs, and after exceeding of this force can slide therein.
