Vehicle seat having an adjusting device
View Patent ↗A vehicle seat ( 1 ) has an adjusting device ( 40 ) for adjusting a relative position between a first component ( 24 ) and a second component ( 30 ) of the vehicle seat ( 1 ). The adjusting device ( 40 ) has a locking device ( 50 ) for locking the adjusting device ( 40 ) by a friction fit between a brake ring ( 60 ) and at least one brake element ( 70 ) of the adjusting device ( 40 ). The brake ring ( 60 ) is directly connected to the first component ( 24 ) or directly connected to the second component ( 30 ).
1. A vehicle seat comprising:
a first component;
a second component; and
an adjusting device for adjusting a relative position between the first component and the second component, wherein the adjusting device comprises a securing device comprising a brake ring, and at least one brake element, the securing device blocking the adjusting device by frictional engagement between the brake ring and the at least one brake element of the adjusting device, wherein the brake ring is directly connected to the first component or directly connected to the second component and the brake ring has a pot shape and is welded and/or adhesively bonded directly to the first component or to the second component.
2. The vehicle seat as claimed in claim 1 , wherein the adjusting device adjusts the seat height adjustment kinematic arrangement.
3. The vehicle seat as claimed in claim 1 , further comprising a seat height adjustment kinematic arrangement wherein the first component is a rear rocker arm of the seat height adjustment kinematic arrangement, and the second component is a seat frame.
4. The vehicle seat as claimed in claim 1 , wherein the brake ring is welded to the first component or to the second component by a laser weld.
5. The vehicle seat as claimed in claim 1 , wherein the brake ring is constructed to be open.
6. The vehicle seat as claimed in claim 1 , wherein the brake ring is constructed to be closed.
7. The vehicle seat as claimed in claim 1 , wherein the adjusting device further comprises a blocking unit for a form-fit locking of the adjusting device.
8. The vehicle seat as claimed in claim 1 , further comprising an actuation element and a pinion, wherein the adjusting device translates a discontinuous movement of the actuation element into a continuous rotational movement of the pinion.
9. The vehicle seat as claimed in claim 1 , wherein the at least one brake element is configured as a rolling member.
10. The vehicle seat as claimed in claim 9 , wherein the at least one brake element configured as a roller.
11. The vehicle seat as claimed in claim 9 , wherein at least one brake element is configured as a ball.
12. The vehicle seat as claimed in claim 1 , wherein the adjusting device has three roller pairs.
13. The vehicle seat as claimed in claim 1 , wherein the brake ring is a clamping ring and in the brake element is a clamping element.
14. The vehicle seat as claimed in claim 13 , wherein the securing device is a clamping member freewheel.
