Abstract
Abstract Lock for safety belts with a belt lock and an insertion tab which can be detented with a detent edge at a latch which can be moved in the belt lock transversely to the direction of insertion. The latch can be shifted by a pressure organ by hand from the detent position against this force of a spring, as well as with an ejector which is braced resiliently against the detented insertion tab. The ejector is formed by a spring element which can be moved into the shifting path of the latch after the insertion tab is withdrawn, and hold the latch in a position outside the insertion path of the insertion tab.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
214 words
Lock for a safety belt comprising a belt lock having a metallic support with two spaced plates defining an insertion path, an insertion tab attached to a belt for insertion in the insertion path of the metallic support, a latch with a detent edge movable transversely to the direction of insertion of the tab to detent the insertion tab, a pressure organ mounted on the metallic support movable by hand against the force of a spring to move the latch transversely out of the detent position, and ejector formed by a spring element disposed in the insertion path ahead of the tab, and when the tab is detented by the latch, is braced resiliently against the detented insertion tab, said spring element, after the pressure organ has moved the latch out of the detent position, pushing the insertion tab out of the insertion path and following the insertion tab as it moves out from the insertion path, with the spring extending in the path beneath the latch to hold the latch in a position outside the inertion path, and wherein the spring element extends at its free spring end beyond the insertion path of the insertion tab and holds the latch in a position in which it is safely removed from the insertion path.
Claim 2
Dependent Claim
214 words
Lock for a safety belt comprising a belt lock having a metallic support with two spaced plates defining an insertion path, an insertion tab attached to a belt for insertion in the insertion path of the metallic support, a latch with a detent edge movable transversely to the direction of insertion of the tab to detent the insertion tab, a pressure organ mounted on the metallic support movable by hand against the force of a spring to move the latch transversely out of the detent position, and ejector formed by a spring element disposed in the insertion path ahead of the tab, and when the tab is detented by the latch, is braced resiliently against the detented insertion tab, said spring element, after the pressure organ has moved the latch out of the detent position, pushing the insertion tab out of the insertion path and following the insertion tab as it moves out from the insertion path, with the spring extending in the path beneath the latch to hold the latch in a position outside the inertion path, and wherein the spring element extends at its free spring end beyond the insertion path of the insertion tab and holds the latch in a position in which it is safely removed from the insertion path.
Claim 3
Dependent Claim
40 words
Lock according to claim 1, wherein said spring element is a coil spring with closely spaced spring end turns which end turn extends in the path beneath the latch to hold the latch in a position outside the insertion path.
Claim 4
Dependent Claim
17 words
Lock according to claim 1, wherein the spring element is designed as a formed or leaf spring.
Claim 5
Dependent Claim
42 words
Lock according to claim 1, wherein the latch is of substantially C-shaped design and has at the free ends facing each other bevels for the insertion tab and at the non-free connecting section at least one shifting surface for a pressure organ.
Claim 6
Dependent Claim
50 words
Lock according to claim 1, wherein the latch is designed as a shaped element with block-like shaft shank having an incline which is located in the center of the transverse path of the latch, and wherein said block has in its cross section a concave run-up surface for the ejector.
Claim 7
Dependent Claim
37 words
Lock according to claim 5, wherein the latch shank at its free end has an incline which is inclined toward a latching edge of the inserted insertion tab and which incline is broken-through by said run-up surface.
Claim 8
Dependent Claim
27 words
Lock according to claim 6, wherein with respect to the insertion path, the angle of inclination of the incline is larger than that of the run-up surface.
Claim 9
Dependent Claim
40 words
Lock according to claim 5 or claim 6 or claim 7, wherein the latch has at least one inclined shifting surface against which a manually operable pressure organ is braced over a large surface for carrying out the shifting stroke.
