A device for locking a vehicle seat has a pawl which can be pivoted about a first pivot axis and, in a closed position, is in engagement with a positionally fixed fitting and, in an open position, is free from the fitting, wherein the pawl has a first clamping surface, furthermore a locking element for locking the pawl in the closed position, which locking element can be pivoted about a second pivot axis and has a second clamping surface which, in a locking position, bears against the first clamping surface and, in the process, keeps the pawl in the closed position, and, in an unlocking position, is free from the first clamping surface, and an actuating element which interacts with the locking element in order to transfer the locking element into the unlocking position. A stop is provided for the actuating element in such a manner that, upon action of a torque exerted by the pawl on the locking element, the actuating element interacts in a blocking manner with the stop and blocks the further movement of the locking element before the latter reaches the unlocking position. In the region of the second clamping surface, the locking element has a material which is softer than a material which the pawl has in the region of the first clamping surface, and the pawl has a projection on which the first clamping surface is at least partially formed.

1. A device for locking a vehicle seat, comprising a pawl pivotable about a first pivot axis and, in a closed position, being in engagement with a positionally fixed fitting and, in an open position, being free from said fitting,said pawl having a projection on which a first clamping surface is at least partially formed, said projection having a first material,a locking element for locking said pawl in said closed position, said locking element being pivotable about a second pivot axis and having a second clamping surface which, in a locking position, bears against said first clamping surface and, thereby, keeps said pawl in said closed position, and, in an unlocking position, is free from said first clamping surface, said locking element, in the region of said second clamping surface, having a second material which is softer than said first material which said pawl has in the region of said first clamping surface, so that the projection of the pawl bores into the second clamping surface of the locking element in the event of high opening torques being exerted by the pawl on the locking element in the event of an impact,an actuating element interacting with said locking element in order to transfer said locking element into said unlocking position, anda stop provided for said actuating element in such a manner that, upon action of a torque exerted by said pawl on said locking element, said actuating element interacts in a blocking manner with said stop and blocks further movement of said locking element before said locking element reaches said unlocking position, wherein the projection extends along a direction of pivoting movement of the pawl about the first pivot axis. 2. The device of claim 1, wherein said actuating element has a limited movement clearance relative to said locking element such that, upon actuation of said actuating element in order to unlock said locking element, said actuating element, after executing a relative movement limited by said movement clearance, runs past said stop, carrying along said locking element. 3. The device of claim 2, wherein said actuating element has a section which, in order to produce said movement clearance, sits with a clearance on a bearing pin of said locking element, which bearing pin forms said second pivot axis. 4. The device of claim 1, wherein said actuating element is connected to said locking element at a connecting point outside said second pivot axis. 5. The device of claim 4, wherein said actuating element can be pivoted about a third pivot axis, said third pivot axis being formed by said connecting point to said locking element. 6. The device of claim 1, wherein said actuating element is prestressed into a position relative to said locking element, in which position said actuating element interacts in a blocking manner with said stop upon action of a torque exerted by said pawl on said locking element. 7. The device of claim 1, wherein the stop is disposed remote from the pawl. 8. A device for locking a vehicle seat, comprising a pawl pivotable about a first pivot axis and, in a closed position, being in engagement with a positionally fixed fitting and, in an open position, being free from said fitting,said pawl having a projection on which a first clamping surface is at least partially formed, said projection having a first material,a locking element for locking said pawl in said closed position, said locking element being pivotable about a second pivot axis and having a second clamping surface which, in a locking position, bears against said first clamping surface and, thereby, keeps said pawl in said closed position, and, in an unlocking position, is free from said first clamping surface, said locking element, in the region of said second clamping surface, having a second material which is softer than said first material which said pawl has in the region of said first clamping surface,an actuating element interacting with said locking element in order to transfer said locking element into said unlocking position, anda stop provided for said actuating element in such a manner that, upon action of a torque exerted by said pawl on said locking element, said actuating element interacts in a blocking manner with said stop and blocks further movement of said locking element before said locking element reaches said unlocking position, wherein the projection extends along a direction of pivoting movement of the pawl about the first pivot axis, and wherein the stop is disposed remote from the pawl.
