Device for locking and unlocking a belt height adjustment device and vehicle seat
First Claim
1. A seat belt height adjustment device for fixed connection to a bearing structure of a vehicle seat, comprising a lever having a first end and a second end, wherein the first end of the lever is pivotably connected to the bearing structure to provide an axis of rotation of the lever relative to the bearing structure, a belt deflection fitting pivotably connected at the second end and rotatably movable relative to the lever, the lever further including a locking device that selectively prevents pivotal movement of the lever relative to the bearing structure;
- wherein the locking device is configured to;
prevent the pivoting of the lever relative to the bearing structure in a downward direction, engages automatically at predetermined lever angle positions on an upward movement of the lever, and on a further upward movement of the lever, said locking device is deactivated when an upper locking position is exceeded so that the lever is movable to a predetermined structurally lower position without remaining in locking positions;
said locking device being formed from a latch and a toothed segment, wherein a first corner portion of the latch is configured to lie spring-loaded on a curved portion of the toothed segment and to travel along said curved portion during rotation of the lever, and during a subsequent upward movement of the lever, the locking device is activated again to prevent downward movement of the lever; and
wherein a guide plate is arranged in a fixed position on the lever and configured to partially encompass the toothed segment to restrict movement of the lever to a vertical direction relative to the bearing structure.

Abstract
The invention relates to a belt height adjustment device for fixed connection to a bearing structure (1) of a vehicle seat, having a lever (2) and a belt deflection fitting (3) which is rotatably movable relative thereto. The lever (2) is pivotably connected to the bearing structure (1) to provide an axis of rotation. The lever (2) further includes a fixing device which can be fixed with respect to its pivotal movement relative to the bearing structure (1). The fixing device is configured to prevent the pivoting of the lever (2) relative to the bearing structure (1), and in particular, in the downward direction, and is configured to engage automatically in prespecified lever angle positions on an upward movement of the lever (2).
