Abstract

The invention concerns a vehicle seat for a vehicle with a seating surface (10), a back rest (12) and at least one foot (14) supporting the seating surface (10), wherein the foot (14) is formed by a connecting means assembly (16) comprising two connecting means (18, 20), namely a first connecting means (18) and a second connecting means (20), each running/extending substantially horizontally, which are each coupled and held spaced in the vertical direction by means of two further connecting means (22, 24), namely a third connecting means (22) and a fourth connecting means (24), such that these four connecting means (18, 20, 22, 24) form a frame (26) which can be connected with the vehicle, and that at least one fifth connecting means is a deformation device (36), wherein the first connecting means (18) is arranged in the vertical direction above the second connecting means (20) and the third connecting means (22) is arranged in the vehicle longitudinal direction in front of the fourth connecting means (24). According to the invention, at least one fifth connecting means (36) which is a deformation device (36) is coupled with the frame (26) via a first connecting point (54) in the region of the first connecting means (18) and is coupled with the vehicle or frame via a second connecting point (56).

Claims

1. A vehicle seat comprising a seating surface, a back rest and at least one foot supporting the seating surface, wherein the foot is formed by a connecting means assembly comprising two connecting means, namely a first connecting means and a second connecting means, each running/extending substantially horizontally, which are each coupled and held spaced in a vertical direction by means of two further connecting means, namely a third connecting means and a fourth connecting means, such that these four connecting means form a frame which can be connected with a vehicle, and that an at least one fifth connecting means is a deformation device, wherein the first connecting means is arranged in the vertical direction above the second connecting means and the third connecting means is arranged in a vehicle longitudinal direction in front of the fourth connecting means, characterised in that the at least one fifth connecting means which is a deformation device is coupled with the frame via a first connecting point in a region of the first connecting means and is coupled with the vehicle or frame via a second connecting point, wherein the deformation device between the connecting points has at least one first section in which it has, in relation to its longitudinal extent, a multiplicity of successive holes, a shape of which can be changed on movement of the first connecting point in relation to the second connecting point;

wherein the second connecting means is divided into a first section, a second section, and a third section, wherein the second section serves to space the third connecting means and the fourth connecting means, wherein the second section connects to the third connecting means and fourth connecting means, wherein the second section, the third connecting means, the fourth connecting means, and the first connecting means form the frame of the foot; and

wherein the deformation device is connected to the frame in the region of the first connecting means and in an upper region of the fourth connecting means, and a second end of the deformation device is arranged in the first section of the connecting means lying outside the frame.

2. The vehicle seat according to claim 1, wherein the deformation device is longer in the deformation configuration than in a main configuration.

3. The vehicle seat according to claim 1, wherein at least two holes are of the same shape and at least partly form an elliptical shape.

4. The vehicle seat according to claim 1, wherein the deformation device in its end regions has coupling regions having slots for coupling with the frame which are oriented differently to each other.

5. The vehicle seat according to claim 1, wherein the frame formed by a first web, a second web, a third web and a fourth web defines a plane running substantially vertically.

6. The vehicle seat according to claim 5, wherein the frame formed by the first web, second web, third web and fourth web is substantially rectangular.

7. The vehicle seat according to claim 1, wherein the foot defines a plane or the first connecting means, second connecting means, third connecting means, fourth connecting means and deformation device extend substantially in a common plane or in planes lying parallel to each other.

8. The vehicle seat according to claim 1, wherein all connecting means of the frame are mobile relative to each other under a predetermined load acting on the frame, in particular such that all connecting means of the frame coupled to each other remain in a coupled state during this relative movement.

9. The vehicle seat according to claim 1, wherein the deformation device is structured such that on stretching of a region, the deformation device has a first stiffness followed by a second stiffness, wherein the second stiffness is greater than the first stiffness.

10. The vehicle seat according to claim 1, wherein the deformation device restricts the relative mobility of all connecting means of the frame which exists under a predetermined load of the frame.

11. The vehicle seat according to claim 1, wherein the frame formed by the first connecting means, second connecting means, third connecting means and fourth connecting means has a trapezoid shape.

12. The vehicle seat according to claim 1, wherein the third connecting means and fourth connecting means have base forms which differ from each other, wherein the third connecting means is U-shaped and the fourth connecting means is S-shaped.

13. The vehicle seat according to claim 1, characterized in that the second section is designed to couple the vehicle seat with the vehicle frame.
