Locking device for a sliding-roof arrangement of a motor vehicle
View Patent ↗A locking device is provided for a sliding-roof arrangement of a motor vehicle with two guide rails which can be arranged so as to be spaced apart in vehicle transverse direction, on which guide rails a slide connectable with a sliding roof is movably mounted. At least one of the slides comprises lock for steplessly locking the slide at random positions of the respective guide rail.
1. A locking device for a sliding-roof arrangement of a motor vehicle, comprising:
a first guide rail;
a second guide rail that is spaced-apart from the first guide rail in relation to a vehicle transverse direction,
a first slide that is connectable with a sliding roof that is movably mounted on the first guide rail, wherein the first slide comprises a claw laterally enclosing the first guide rail at a free end of which a contact roller is arranged for engagement with one of a top side and an underside of the first rail;
a second slide that is connectable with the sliding roof that is movable mounted on the second guide rail; and
a lock for the first slide that is configured to steplessly lock at random positions of the first guide rail.
2. The locking device according to claim 1 , wherein the second slide is slidable on a track roller mounted along the second guide rail.
3. The locking device according to claim 1 , wherein the lock is configured to operate in a friction-lock manner.
4. The locking device according to claim 1 , wherein the lock is configured to operate in a force-lock contact manner.
5. The locking device according to claim 1 , wherein the first slide comprises at least two track rollers spaced-apart in a sliding direction that are configured for engagement with a topside of the first guide rail.
6. The locking device according to claim 1 , wherein the first slide comprises at least two track rollers spaced-apart in a sliding direction that are configured for engagement with an underside of the first guide rail.
7. The locking device according to claim 6 , wherein the contact roller is a spring-loaded contact roller arranged for engagement with the topside of the first guide rail.
8. The locking device according to claim 6 , wherein the contact roller is a spring-loaded contact roller arranged for engagement with the underside of first guide rail.
9. The locking device according to claim 2 , wherein the track roller comprises a static friction-promoting coating at an outer circumference.
10. The locking device according to claim 2 , wherein the track roller comprises a static friction-promoting coating at an outer circumference.
11. The locking device according to claim 9 , further comprising a brake shoe movable with an actuating cable that is arranged on the first slide,
wherein the brake shoe is configured to engage with the track roller.
12. The locking device according to claim 11 ,
wherein the first slide and the second slide are movably mounted opposite each other on the first guide rail and the second guide rail in the vehicle transverse direction and in parallel thereto,
wherein the locking device further comprises the brake shoe that is configured for engagement with the track roller,
wherein the brake shoe is coupled with the actuating cable extending along the sliding roof in the vehicle transverse direction.
13. The locking device according to claim 12 , wherein the brake shoe is tensioned and in engagement with the track roller and transferable into a release position against a spring force.
