Abstract

There is provided a motor vehicle seat with a seat support, which is constructed of two sections, namely of a front part and of a back part, which are connected with each other via two side connecting areas and that for an adjustment of the seat depth, the side connecting areas each have a long hole, into which an axle pin is led and that a device exists for the mechanical adjustment and fixation of the two sections in opposition to each other.

Claims

1. A motor vehicle seat having a seat support comprising:

a front part a back part, two side connecting areas, and axle pins;

said front part and said back part are connected to each other by said side connecting areas;

each said side connecting area further having a long hole;

said axle pins being led through said long holes wherein a longitudinal adjustment of the seat support and the seat depth is adjusted; and

a means to mechanically adjust and fix said front part in opposition to said back part, providing displacement of the axle pins in the long holes and thereby a longitudinal adjustment of the seat support;

a backrest connected to said seat support;

tension springs, wherein the front part and the back part of said seat support are connected by said tension springs that run essentially crosswise to said backrest;

said tension springs further comprising a back area and a front area, said back area engaged at said back part and said front area engaged at said front part;

the front part having a seat pillow, a seat pillow pad, and V-shaped individual springs, wherein a back area of the V-shaped springs is positioned behind said pad of the seat pillow.

2. The motor vehicle seat according to claim 1 further comprising a transverse part, wherein said front area and back area of the spring each is comprised of a plurality of individual springs, said individual springs being arranged in a line, and said individual springs of the front area and of the back area of the spring engage onto said transverse part.

3. The motor vehicle seat according to claim 2 whereine said transverse part is further comprised of two side legs having a front part and a loose end, said side legs being hinged, at said front part with said loose ends, and said side legs being further arranged in such a way that they withstand tensile stress and resistance to pressure.

4. The motor vehicle seat according to claim 1 further comprising an elastic bedding for dampening, wherein said elastic bedding is proximate to said long holes and said axle pin is between said long hole and said axle pin.

5. The motor vehicle seat according claim 1 further comprising a backrest and a continually covering seat upholstery, said upholstery having a prolonged area, and said upholstery running across the front part to the back part and that in an area below said backrest of the motor vehicle seat said prolonged area is embodied as said seat pillow pad.

6. A motor vehicle seat having a seat support comprising:

a front part having a seat pillow and a seat pillow pad, a back part, two side connecting areas, and axle pins;

said seat pillow pad having V-shaped individual springs, a front area of said springs being constructed for an upholstery of said seat pillow;

said front part and said back part are connected to each other by said side connecting areas;

each said side connecting area further having a long hole;

said axle pins being led through said long holes wherein a longitudinal adjustment of the seat support and the seat depth is adjusted; and

a means to mechanically adjust and fix said front part in opposition to said back part providing displacement of the axle pins in the long holes and thereby a longitudinal adjustment of the seat support;

a backrest connected to said seat support;

tension springs, wherein the front part and the back part of the seat support are connected by said tension springs that run essentially crosswise to said backrest;

said tension springs further comprising a back area and a front area, said back area engaged at said back part and said front area engaged at said front part

said tension springs including said V-shaped individual springs, wherein a back area of said V-shaped springs is positioned behind said pad of the seat pillow.
