Abstract

In the case of a seat back for vehicle seats, in particular motor vehicle seats, with two side outriggers (1), which consist of a back and front support (3,4), which are connected in the area of their lower end section through a connecting body (5) and above the connecting body to each other, both the front support (4) and the back support (3) continue into the transverse spar (2), which connects the side outriggers (1) to each other in the area of its upper end. The front support (4) lies above the connecting body (5) and below the transverse spar (2) on a piece of its segment on the back support (3). On transverse parts (6,7) of the back and front supports (3,4) that extend from one side outrigger (1) to the other in the area of the transverse spar (2) are positioned at an interval from one another over each other. Both transverse parts (6,7) are connected to each other so they are rigid by means of a separator (8) abutting on them.

Claims

1. Seat back for vehicle seats, comprising two side outriggers and a transverse spar connected between upper ends of said outriggers whereby each of the two side outriggers are forms of a back support and a front support, said front and back supports are connected to each other in a lower end section of each said support through a connecting body and directly abort one another above the connecting body, from which the front support continues into the transverse spar:

wherein the back support also continues into the transverse spar such that

said front support includes a transverse part and said rear support includes a transverse part both said transverse parts form said transverse span which runs from one outrigger to an opposite outrigger, and are positioned at an interval from each other above each other; and

wherein the two transverse parts are rigidly connected to one another through a separator mounted there between.

2. Seat back according to claim 1, wherein the separator is a holding device for a headrest.

3. Seat back according to claim 2, wherein the transverse parts further comprise a flattened out segment on each of their front sides and both flattened out segments lying on a common plane from mounting the separator thereon.

4. Seat back according to claim 3, wherein the transverse part of the rear support lies below the transverse part of the front support.

5. Seat back according to claim 4, wherein each connecting body is formed as an extruded section having two channels for engaging a lower end section of the front support and engaging a lower end section of the back support, and each connecting body including an extension part, which is formed on material parts lying between channels and which protrudes upward over the part of the connecting body with the channels to prop the two supports against each other.

6. Seat back according to claim 5, wherein the extension part has an shaped profile section.

7. Seat back according to claim 6, wherein the supports are formed by pipes.

8. Seat back according to claim 7, wherein a flat cushion support is secured between both rear supports.
