Abstract

A vehicle seat ( 1 ) has a seat segment ( 14 ) with a first seat ( 11 ) having a first backrest ( 21 ) and a second seat ( 12 ) having a second backrest ( 22 ) and a seat part ( 24 ). The first backrest and the second backrest are pivotable about a pivot axis (A) relative to the seat part. A first fitting ( 51 ) and a second fitting ( 52 ) connect the first backrest to the seat part. The fittings ( 51, 52 ) each have a fitting part fixed to the seat part and a fitting part fixed to the backrest that are pivotable relative to one another. The second backrest is pivotable about the pivot axis (A) via a first rotary bearing point ( 71 ) that is a fixed bearing and via a second rotary bearing part ( 72 ) that is a floating bearing. The second rotary bearing point includes a rotary bearing sleeve ( 54 ) mounted on the first fitting.

First claim

1 . A vehicle seat having a seat segment comprising:
a first seating position with a first backrest a second seating position with a second backrest; a seat part, the first backrest and the second backrest being pivotable about a pivot axis relative to the seat part, and a first fitting; a second fitting, the first backrest being connected to the seat part by the first fitting and the second fitting, the fittings in each case having a fitting part which is fixed to the seat part and a fitting part which is fixed to the backrest, which fitting parts can be pivoted relative to one another, wherein the second backrest can be pivoted about the pivot axis by means of a first pivot bearing point which is configured as a locating bearing and by means of a second pivot bearing point which is configured as a floating bearing, and the second pivot bearing point comprises a pivot bearing sleeve which is fastened to the first fitting.

2 . The vehicle seat as claimed in claim 1 , wherein the first pivot bearing point comprises a fastening pin which engages through a lower part which is provided on the seat part and through a side part which is provided on the second backrest.

3 . The vehicle seat as claimed in claim 1 , wherein the pivot bearing sleeve is fastened to a fitting part of the first fitting which is fixed on the seat part.

4 . The vehicle seat as claimed in claim 1 , wherein the pivot bearing sleeve is fastened to a fitting part of the first fitting which is fixed on the backrest.

5 . The vehicle seat as claimed in claim 1 , wherein the pivot bearing sleeve is configured in the form of a hollow cylinder.

6 . The vehicle seat as claimed in claim 5 , wherein a cylinder axis, which is defined by the pivot bearing sleeve, is aligned with the pivot axis.

7 . The vehicle seat as claimed in claim 1 , wherein a catching contour is attached to the pivot bearing sleeve, which catching contour prevents releasing of the second backrest from the pivot bearing sleeve in the case of a crash.

8 . The vehicle seat as claimed in claim 1 , wherein the second pivot bearing point comprises a pivot bearing pin.

9 . The vehicle seat as claimed in claim 8 , wherein the pivot bearing pin is of rotationally symmetrical configuration.

10 . The vehicle seat as claimed in claim 9 , wherein a cylinder axis, which is defined by the pivot bearing pin, is aligned with the pivot axis.

11 . The vehicle seat as claimed in claim 8 , wherein the pivot bearing pin is fastened to the first fitting.

12 . The vehicle seat as claimed in claim 1 , wherein the second pivot bearing point has a transmission rod for actuating the first fitting.

13 . The vehicle seat as claimed in claim 12 , wherein a two-piece bearing sleeve or a ball bearing is mounted on the transmission rod.

14 . The vehicle seat as claimed in claim 1 , wherein the fittings are configured as latching fittings.

15 . The vehicle seat as claimed in claim 1 , wherein the fittings are configured as gear mechanism fittings.
