Abstract

The invention relates to a locking and inclination-adjustment assembly for locking and adjusting the inclination of a part, especially a pivotable backrest (R, R 1 , R 2 ) of a vehicle, comprising a lock striker ( 30 ) arranged on the car body and a lock (S) arranged on the part, said lock (S) being joined to the lock striker ( 30 ) when in a locked position (I, II) and being detachable from the lock striker ( 30 ) when in an unlocked position (III). It is provided that the lock (S) arranged on the part has rotary catches ( 10, 20 ) with corresponding locking pawls ( 15, 25 ), whereby the part can be moved and locked in several reversible latching positions (I, II) on the lock striker ( 30 ) that engages with the lock (S), and the part can be moved into the unlocked position (III) separately from the lock striker ( 30 ).

First claim

The invention claimed is:

1. A locking and inclination-adjustment assembly for locking and adjusting the inclination of a part of a vehicle comprising
a lock striker arranged on a vehicle body, and
a lock arranged on the part, said lock being joined to the lock striker when in a locked position and being detachable from the lock striker when in an unlocked position,
wherein the lock arranged on the part has rotary catches with corresponding locking pawls, whereby the part can be moved and locked in several reversible latching positions on the lock striker that engages with the lock, and the part can be moved into the unlocked position separately from the lock striker,
wherein, when the part is in the unlocked position, it can be locked in one of the rotary catches in one latching position or another as a result of a speed-dependent folding movement of the part, and
wherein, when the part is in the unlocked position, it is locked in a first latching position in a first rotary catch as a result of a folding movement at a first speed, or else it is locked in a second latching position in a second rotary catch as a result of a folding movement at a second speed, wherein the first speed is slower than the second speed.

2. The locking and inclination-adjustment assembly according to claim 1 , wherein the actuation of a first actuation mechanism associated with the assembly adjusts the various inclinations of the part, from one latching position to the other and vice versa.

3. The locking and inclination-adjustment assembly according to claim 2 , wherein the adjustment of the various inclinations of the part from one latching position to the other and vice versa takes place by actuating a first actuation mechanism, without causing the part to move into the unlocked position.

4. The locking and inclination-adjustment assembly according to claim 2 , wherein the lock striker unlocks the part from each of the latching positions of the part, moving it into the unlocked position, exclusively by actuating a second actuation mechanism that is associated with the assembly.

5. The locking and inclination-adjustment assembly according to claim 1 , wherein the lock arranged on the part has a first and a second rotary catch with corresponding locking pawls, whereby the part can be moved and detachably locked in a first latching position in the first rotary catch or in a second latching position in the second rotary catch on the lock striker that engages with the lock.

6. The locking and inclination-adjustment assembly according to claim 1 , wherein, by means of a backrest-folding mechanism associated with the assembly, the part can be automatically moved with the assistance of springs out of the latching positions into the unlocked position, or out of the second latching position into the first latching position.

7. A vehicle having a locking and inclination-adjustment assembly according to claim 1 .

8. The vehicle according to claim 7 , wherein the actuation of a first actuation mechanism associated with the assembly adjusts the various inclinations of the part, from one latching position to the other and vice versa.

9. The vehicle according to claim 8 , wherein a second actuation mechanism allows the part to be unlocked from each of the latching positions into the unlocked position, whereby a control signal can be impinged onto the second actuation mechanism, thus only allowing a complete unlocking of the part if the vehicle is not moving.
