Abstract

A vehicle seat is disclosed as having a seat structure with an upper transverse strut for receiving a headrest of the vehicle seat. The headrest has right and left headrest rods for coupling with the upper transverse strut. The transverse strut 6 includes right and left receiving openings for the right and left headrest rods. The headrest may be arranged with the headrest rods in various guide channels to define first and second mounting positions relative to the upper transverse strut. The headrest in the first mounting position is offset transversely to the seat direction with respect to the headrest in the second mounting position.

First claim

What is claimed is:

1. A vehicle seat for a vehicle comprising:
a seat frame including an upper transverse strut having a right opening for receiving a right guide channel in a first and second position and a left opening laterally spaced from the right opening for receiving a left guide channel in a first and second position; and
a headrest having a right headrest rod arranged in the right guide channel and a left headrest rod spaced apart from the right headrest rod and received in the left guide channel, the headrest being configured to couple with the upper transverse strut in a first mounting position wherein the right headrest rod is received in the right guide channel in the first position and the left headrest rod is received in the left guide channel in the first position, and a second mounting position wherein the right headrest rod is received in the right guide channel in the second position and the left headrest rod is received in the left guide channel in the second position;
wherein the headrest is offset transversely to a seat direction in the first mounting position with respect to the headrest in the second mounting position.

2. The vehicle seat according to claim 1 , wherein the first mounting position is associated with a first seat track of the vehicle seat for a first segment vehicle, and wherein the second mounting position is associated with a second seat track of the vehicle seat for a second segment vehicle, wherein the second seat track is different from the first seat track.

3. The vehicle seat according to claim 2 , wherein the fight and left opening are arranged mirror-symmetrically to an averaged seat track averaged from the first and second seat tracks.

4. The vehicle seat according to claim 1 ; wherein the upper transverse strut has a horizontal underside, the vehicle seat further comprising:
a right locking device constructed on the horizontal underside for locking the right headrest rod in the upper transverse strut, wherein the right guide channel opens into the right locking device; and
a left locking device on the horizontal underside for locking the left headrest rod in the upper transverse strut, wherein the left guide channel opens into the left locking device.

5. The vehicle seat according to claim 4 wherein the right and left locking devices are constructed as keyhole openings.

6. The vehicle seat according to claim 1 , wherein the right and left opening are constructed as elongated holes on a horizontal upper side of the upper transverse strut, each of the elongated holes having a first cutout defining the first position and a second cutout defining the second position for receiving a guide bush for the right and left headrest rods.

7. The vehicle seat according to claim 6 , wherein the upper transverse strut has a horizontal underside, the vehicle seat further comprising:
a right locking device constructed on the horizontal underside for locking the right headrest rod in the upper transverse strut, wherein the right guide channel opens into the right locking device; and
a left locking device on the horizontal underside for locking the left headrest rod in the upper transverse strut, wherein the left guide channel opens into the left locking device.

8. The vehicle seat according to claim 7 , further comprising a pair of guide bushes including a right guide bush placed onto the right headrest rod to position the right headrest rod in the right opening, guide the right headrest rod in the right guide channel and fix the right headrest rod in the right locking device, and a left guide bush placed onto the left headrest rod to position the left headrest rod in the left receiving opening, guide the left headrest rod in the left guide channel and fix the left headrest rod in the left locking device.

9. The vehicle seat according to claim 8 , wherein each of the pair of guide bushes comprise a radially projecting flange at an upper end for covering the opening of the upper transverse strut, the flange having a positioning pin configured to engage into the right or the left positioning cutout of the opening, wherein the headrest is mounted in the first mounting position when the positioning pin engages into the first positioning cutout and is mounted in the second mounting position when the positioning pin engages into the second positioning cutout.

10. The vehicle seat according to claim 8 , wherein each of the pair of guide hushes comprise two radially circumferentially arranged spring devices arranged at a lower end for engagement and locking in the right and left locking device.

11. A vehicle fleet comprising:
a first segment vehicle;
a second segment vehicle; and
a plurality of vehicle seats according to claim 1 ;
wherein the first segment vehicle includes a first vehicle seat of the plurality of vehicle seats, the first vehicle seat having the headrest configured in the first mounting position; and
wherein second segment vehicle includes a second vehicle seat of the plurality of vehicle seats, the second vehicle seat having the headrest configured in the second mounting position.

12. The vehicle fleet according to claim 11 , wherein the right headrest rod of the first vehicle seat is arranged in the right guide channel and the left headrest rod is arranged in the left guide channel and at the same time are arranged mirror-symmetrically to a first seat track when the vehicle seat is arranged in the first segment vehicle.

13. The vehicle fleet according to claim 12 , wherein a flange projects radially to the right from a guide bush and a positioning pin engages into a right positioning cutout of the right or respectively left opening, when the vehicle seat is arranged in the first segment vehicle.

14. The vehicle fleet according to one of claim 11 , wherein the right headrest rod is arranged in the right guide channel and the left headrest rod is arranged in the left guide channel and at the same time are arranged mirror-symmetrically to a second seat track when the vehicle seat is arranged in the second segment vehicle.

15. The vehicle fleet according to claim 14 , wherein a flange projects radially toward the left from the guide bush and the positioning pin engages into a left positioning cutout of the right or respectively left opening when the vehicle seat is arranged in the second segment vehicle.

16. The vehicle fleet according to claim 11 , wherein the first vehicle seat includes at least one first seat upholstery configured mirror-symmetrically to the first seat track when the vehicle seat is arranged in the first segment vehicle.

17. The vehicle fleet according to claim 11 , wherein the second vehicle seat includes at least one second seat upholstery configured mirror-symmetrically to a second seat track when the vehicle seat is arranged in the second segment vehicle.
