Abstract

The present invention relates to a vehicle seat ( 1 ), comprising a seat element ( 2 ), which can be height-adjusted from a usage position to a stowing position, and comprising a backrest element ( 3 ), wherein the backrest element ( 3 ) can be pivoted about a stationary primary axis (A), wherein the backrest element ( 3 ) is operatively connected to the seat element ( 2 ) by means of an articulated system in such a way that the seat element ( 2 ) can be transferred from the usage position to the stowing position by means of a pivoting motion of the backrest element ( 3 ), wherein the articulated system has a deflecting element ( 7 ), wherein the deflecting element ( 7 ) can be pivoted about a stationary secondary axis (B), wherein a secondary plane (B′), which extends perpendicularly to the direction of travel (D) and comprises the secondary axis (B), is arranged in front of a primary plane (A′), which extends perpendicularly to the direction of travel (D) and comprises the primary axis (A), in a direction extending parallel to the direction of travel (D).

First claim

The invention claimed is:

1. A vehicle seat having a seat element, which is vertically adjustable from a use position into a storage position, and a backrest element, wherein the backrest element is pivotable about a positionally fixed primary axis, wherein the backrest element is operatively connected to the seat element via an articulation system in such a manner that, by means of a pivoting movement of the backrest element, the seat element is transferable from the use position into the storage position, wherein the articulation system has a deflection element, wherein the deflection element is pivotable about a positionally fixed secondary axis, wherein a secondary plane, which is oriented perpendicularly to a direction of travel and comprises the secondary axis, is arranged, in terms of a direction parallel to the direction of travel, in front of a primary plane, which is oriented perpendicularly to the direction of travel and comprises the primary axis, and wherein, in the storage position, the seat element is arranged offset rearward in the direction of travel in relation to the use position, and wherein the deflection element and the backrest element are pivoted along a same direction of rotation during a transition of the seat element from the use position into the storage position.

2. The vehicle seat as claimed in claim 1 , wherein the vehicle seat has a base part, wherein
the backrest element is coupled to the base part so as to be pivotable about the positionally fixed primary axis, and
the deflection element is coupled to the base part so as to be pivotable about the positionally fixed secondary axis.

3. The vehicle seat as claimed in claim 2 , wherein the seat element has a seat element carrier, wherein the seat element carrier comprises a guide slot, wherein the seat element carrier is connected to the base part via the guide slot so as to be displaceable with respect to the base part.

4. The vehicle seat as claimed in claim 2 , wherein the vehicle seat has a link connecting the seat element and the base part, wherein the link is arranged on the seat element so as to be pivotable about a tertiary axis.

5. The vehicle seat as claimed in claim 1 , wherein the articulation system has a first coupling element and a second coupling element, wherein the first coupling element connects the backrest element and the deflection element to each other, and wherein the second coupling element connects the seat element and the deflection element to each other.

6. The vehicle seat as claimed in claim 1 , wherein the secondary axis is arranged more than 5 cm in front of the primary axis along the direction parallel to the direction of travel.

7. The vehicle seat as claimed in claim 6 , wherein the secondary axis is arranged more than 10 cm in front of the primary axis along the direction parallel to the direction of travel.

8. The vehicle seat as claimed in claim 7 , wherein the secondary axis is arranged more than 15 cm in front of the primary axis along the direction parallel to the direction of travel.

9. The vehicle seat as claimed in claim 1 , wherein the deflection element has a first lever arm and a second lever arm, wherein the first lever arm is arranged at a deflection element angle with respect to the second lever arm, wherein the deflection element angle is between 90° and 180°.

10. The vehicle seat as claimed in claim 9 , wherein the first lever arm is longer than the second lever arm.

11. The vehicle seat as claimed in claim 9 , wherein the deflection element angle is about 135°.

12. A method for stowing a vehicle seat as claimed in claim 1 , wherein pivoting the backrest element about the primary axis causes the deflection element to pivot about the secondary axis.
