Abstract

A vehicle seat includes an adjusting device, for example for adjusting the height and/or tilt of a seat part structure and/or of a backrest structure connected to the seat part structure, wherein the adjusting device is fastened to the seat part structure.

First claim

The invention claimed is:

1. A vehicle seat comprising:
an adjusting device through which at least one of a seat part structure and a backrest is adjustable relative to a body of a vehicle, wherein the adjusting device includes:
a braking ring which is part of a releasable locking mechanism of an adjusting gear, wherein the adjusting gear is configured to adjust at least one of a height and tilt of at least one of the seat part structure and the backrest,
wherein the braking ring has a substantially circular cross-sectional area,
wherein the braking ring includes a plurality of grooves formed on a portion of the braking ring that extend within the substantially circular cross-sectional area of the braking ring,
wherein the grooves are arranged equidistantly from one another on the braking ring when the braking ring includes more than two grooves;

a housing surrounding at least one of the braking ring and the adjusting gear,
wherein the housing has an opening on one side through which the adjusting gear is connectable to at least one of a drive, handle, wheel, and lever,
wherein the housing comprises a plurality of fastening wedges,
wherein the fastening wedges are configured to engage in a form-locking manner in the grooves in order to fix the braking ring and the housing together such that relative movement in at least one of the axial and radial direction between the housing and the braking ring is prevented,
wherein the braking ring includes a threaded flange that has a thread; and

a nut including a mating thread that is configured to engage with the thread of the threaded flange of the braking ring,
wherein the nut is configured to form a clamping gap between the braking ring and the nut when the mating thread of the nut is engaged with the thread of the threaded flange,
wherein the clamping gap is configured to receive a portion of the seat part structure and the nut is configured to clamp the portion of the seat part structure within the clamping gap between the braking ring and the nut as the mating thread of the nut is threaded onto the thread of the threaded flange of the braking ring,
wherein the clamping of the portion of the seat part structure fastens the adjusting device to the portion of the seat part structure such that at least one of the height and tilt of at least one of the seat part structure and of the backrest can be adjusted.

2. The vehicle seat as claimed in claim 1 , wherein the thread of the threaded flange is configured to extend through an opening in the portion of the seat part structure.

3. The vehicle seat as claimed in claim 1 , wherein the braking ring has an aligning mechanism which interacts with the seat part structure or the backrest and fixes the braking ring in its position.

4. The vehicle seat as claimed in claim 1 , wherein the braking ring is connected in an integrally bonded manner to the seat part structure or the backrest.

5. The vehicle seat as claimed in claim 1 , wherein the braking ring is one piece with the seat part structure.

6. The vehicle seat as claimed in claim 1 , wherein the adjusting device is at least one of a seat structure part height adjuster and seat structure part tilt adjuster.

7. The vehicle seat as claimed in claim 1 , wherein the braking ring is rotationally and axially secured to at least one of the seat part structure and the backrest.

8. The vehicle seat as claimed in claim 1 , wherein the braking ring directly contacts at least one of the seat part structure and the backrest.

9. The vehicle seat as claimed in claim 1 , wherein the braking ring and the nut each directly contact the portion of the seat part structure that is clamped within the clamping gap while the mating thread of the nut is threaded onto the thread of the threaded flange of the braking ring.

10. The vehicle seat as claimed in claim 1 , wherein the braking ring directly contacts a first side of the portion of the seat part structure that is clamped within the clamping gap and the nut directly contacts a second side of the portion of the seat part structure that is clamped within the clamping gap while the mating thread of the nut is threaded onto the thread of the threaded flange of the braking ring.
