Abstract

A vehicle seat is provided. The vehicle seat comprising a seat member, a backrest member which is connected to the seat member so as to be able to be pivoted about a pivot axis, a first fitting which, when viewed along the pivot axis, is arranged at a first position on the seat member and a second fitting which, when viewed in the direction of the pivot axis, is arranged at a second position on the seat member for a pivotable connection of the backrest member with the seat member. The vehicle seat further comprising a third fitting which, when viewed along the pivot axis is arranged between the first fitting and the second fitting and which is spaced apart from the first fitting and the second fitting along the pivot axis.

First claim

The invention claimed is:

1. A vehicle seat comprising
a seat member,
a backrest member which is connected to the seat member so as to be pivotable about a pivot axis with respect to the seat member,
a first fitting which, when viewed along the pivot axis, is arranged at a first position on the seat member and a second fitting which, when viewed in the direction of the pivot axis, is arranged at a second position on the seat member for a pivotable connection of the backrest member with the seat member,
a third fitting which, when viewed along the pivot axis, is arranged between the first fitting and the second fitting and which is spaced apart from the first fitting and the second fitting along the pivot axis,
wherein the first fitting is connected to a first frame member of the backrest member, the second fitting is connected to a second frame member of the backrest member, and the third fitting is connected to a third frame member of the backrest member,
wherein the first frame member, the second frame member and the third frame member of the backrest member are connected to each other such that the first frame member, the second frame member and the third frame member of the backrest member are pivoted together when pivoting the backrest member relative to the seat member upon actuating the first fitting, the second fitting and the third fitting,
wherein the first fitting is connected to a first frame member of the seat member, the second fitting is connected to a second frame member of the seat member, and the third fitting is connected to a third frame member of the seat member,
wherein the first frame member of the seat member and the second frame member of the seat member are connected to each other by a transverse pipe extending from the first frame member of the seat member to the second frame member of the seat member, and wherein the third frame member of the seat member is supported on the transverse pipe in that the third frame member of the seat member is butt-welded to the transverse pipe or is screwed to the transverse pipe.

2. The vehicle seat as claimed in claim 1 , wherein the third fitting is arranged on the seat member at a position of a belt connection location.

3. The vehicle seat as claimed in claim 1 , wherein the first fitting and the second fitting are spaced apart from each other by a first distance along the pivot axis and the third fitting is spaced apart from the first fitting by a second distance lying in a range between 0.2 and 0.8 times the first distance.

4. The vehicle seat as claimed in claim 3 , wherein the second distance equals 0.6 times the first distance.

5. The vehicle seat as claimed in claim 1 , wherein a fourth fitting, when viewed along the pivot axis, is arranged between the first fitting and the second fitting, and is spaced apart from the first fitting, the second fitting and the third fitting along the pivot axis.

6. The vehicle seat as claimed in claim 5 , wherein the first fitting and the second fitting are spaced apart from each other along the pivot axis by a first distance, wherein the first fitting is spaced apart from the third fitting by a second distance in the range between 0.25 and 0.45 times the first distance, and the second fitting is spaced apart from the fourth fitting by a third distance in the range between 0.25 and 0.45 times the first distance.

7. The vehicle seat as claimed in claim 6 , wherein the second distance and the third distance equal 0.33 times the first distance.

8. The vehicle seat as claimed in claim 6 , wherein the second distance and the third distance each equal 0.4 times the first distance.

9. The vehicle seat as claimed in claim 1 , wherein each of the fittings are each constructed as rotary fittings.

10. The vehicle seat as claimed in claim 9 , wherein the fittings are connected to a shaft which extends along the pivot axis in order to actuate the fittings.

11. The vehicle seat as claimed in claim 10 , further comprising an electrical actuation device for driving the shaft.

12. The vehicle seat as claimed in claim 1 , wherein the first fitting and the second fitting are constructed as rotary fittings and the third fitting and optionally additional fittings are constructed as catch fittings.

13. The vehicle seat as claimed in claim 12 , wherein the first fitting and the second fitting are connected to a shaft which extends along the pivot axis in order to actuate the fittings.

14. The vehicle seat as claimed in claim 1 , wherein each of the fittings are structurally identical.

15. The vehicle seat as claimed in claim 1 , wherein the first fitting and the second fitting are structurally identical and the third fitting and optionally additional fittings have smaller dimensions.

16. The vehicle seat as claimed in claim 1 , wherein the first fitting and the second fitting are structurally identical and the third fitting and optionally additional fittings have larger dimensions.

17. The vehicle seat as claimed in claim 1 , wherein the first fitting and the second fitting are spaced apart from each other by a first distance along the pivot axis and the third fitting is spaced apart from the first fitting by a second distance lying in a range between 0.35 and 0.65 times the first distance.
