Abstract
Abstract Latch mechanism for safety belts provided with belt means and two connectable members, provided for a releasable anchoring of the belt means to a vehicle. One of said members consists of a locking member and the other member consists of a latch member. The latch member comprises at least one locking device, which is movable between a first, unlocking position releasing the locking member and a second position, locking the same. The latch member further comprises maneuvering means, provided to be actuated from the outside of the latch member for said moving of the locking device and to be caught in a position in which the locking device is retained in its first, unlocking position when the locking member is disconnected from the latch member, and a frame for the guiding of the locking device and the maneuvering device. A part is provided in the locking, second position of the locking device to force the maneuvering device to form a play between at least one first catch surface of the maneuvering device and at least one corresponding second catch surface connected to the frame and to release the same device from said force by the release of the locking member, admitting said catching of the maneuvering device by means of cooperation between said catch surfaces by eliminating said play.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
433 words
Latch mechanism for the connection of two parts of a safety belt means and including a locking member attached to one part and a latch member attached to the other part of said means, said latch member comprising a frame having a channel in which the locking member is insertable to connect the two members, locking means movable in the frame between a releasing position out of the channel and a locking position located in the channel and cooperating with rest surfaces of the locking member when the locking means is inserted in the channel and locking the same, maneuvering means movable in the frame between a first and a second position and biased to move towards the second position, said maneuvering means being in driving connection with the locking means for actuating the same to be in its releasing position when the maneuvering means is in its first position and to be in the locking position when the maneuvering means is in its second position, a rejector element movable between an outer position in which it is biased to reject the locking member out of the channel when the same is released by the locking means and an inner position to which the rejector element is forced by the locking member when it is in its inserted position in the channel, and a catching mechanism arranged to be in an actuating position holding the maneuvering means in its first position when the rejector element is in its outer position or adjacent to its outer position and to free the maneuvering means to move to its second position when the rejector element is in or is adjacent to its inner position, said catching mechanism comprising at least one element connected to the frame and provided with a first rest surface and at least one element connected to the maneuvering means and provided with a second rest surface which is provided to be positioned behind the first rest surface when the catching mechanism is in its actuating position, whereby the rest surfaces are positioned so that the second rest surface is at a small distance behind the first rest surface when the maneuvering means is in its innermost position, the catching mechanism further comprising means connected to the rejector element and provided to obstruct the elements provided with the rest surfaces to be in front of each other when the rejector element is in its inner position and to free the elements to move in front of each other when the rejector element is in its outer position or adjacent to its outer position.
Claim 2
Dependent Claim

Latch mechanism for the connection of two parts of a safety belt means and including a locking member attached to one part and a latch member attached to the other part of said means, said latch member comprising a frame having a channel in which the locking member is insertable to connect the two members, locking means movable in the frame between a releasing position out of the channel and a locking position located in the channel and cooperating with rest surfaces of the locking member when the locking means is inserted in the channel and locking the same, maneuvering means movable in the frame between a first and a second position and biased to move towards the second position, said maneuvering means being in driving connection with the locking means for actuating the same to be in its releasing position when the maneuvering means is in its first position and to be in the locking position when the maneuvering means is in its second position, a rejector element movable between an outer position in which it is biased to reject the locking member out of the channel when the same is released by the locking means and an inner position to which the rejector element is forced by the locking member when it is in its inserted position in the channel, and a catching mechanism arranged to be in an actuating position holding the maneuvering means in its first position when the rejector element is in its outer position or adjacent to its outer position and to free the maneuvering means to move to its second position when the rejector element is in or is adjacent to its inner position, said catching mechanism comprising at least one element connected to the frame and provided with a first rest surface and at least one element connected to the maneuvering means and provided with a second rest surface which is provided to be positioned behind the first rest surface when the catching mechanism is in its actuating position, whereby the rest surfaces are positioned so that the second rest surface is at a small distance behind the first rest surface when the maneuvering means is in its innermost position, the catching mechanism further comprising means connected to the rejector element and provided to obstruct the elements provided with the rest surfaces to be in front of each other when the rejector element is in its inner position and to free the elements to move in front of each other when the rejector element is in its outer position or adjacent to its outer position.
Claim 3
Dependent Claim
117 words
Latch mechanism according to claim 1 in which the means obstructing the first and second surfaces to be in front of each other is an elongated portion on the rejector element arranged to be inserted between the elements provided with the first and the second rest surfaces and forcing the elements to be out of line with each other when the rejector element is in its inner position, said elongated portion being provided with a terminating edge which is positioned to be at a distance from the first rest surface when the rejector element is in its outer position so that the elements provided with said surfaces are free to be biased in front of each other.
Claim 4
Dependent Claim
167 words
Latch mechanism according to claim 2 in which the maneuvering means comprises an element which is movable in the frame between its first and second positions and provided with at least one portion forming said element with the second rest surface, said portion being movable in a direction crosswise to the direction of the movement of the element between the first and the second positions, the frame being provided with at least one portion forming a guiding surface terminating with an edge forming the first rest surface, the portion of the maneuvering means being arranged to slide on said guiding surface by the movement of the element between its first and second positions and to move in the crosswise direction when the portion provided with the second surface reaches the edge of the guiding portion and when the rejector element is in its outer position or adjacent to its outer position, so that said portion of the maneuvering means is free to move in said crosswise direction.
Claim 5
Dependent Claim
43 words
Latch mechanism according to claim 3 in which the terminating edge of the elongated portion of the rejector element is wedge-like and provided to be inserted between the elements with the rest surfaces when the rejector element is moved to its inner position.
