Abstract

The invention relates to a vehicle seat ( 1 ) comprising a seat element ( 2 ) which can be pivoted from a use position into a stowed position. Said vehicle seat comprises locking means ( 14 ). Said locking means interact with the seat element ( 2 ) in a positive and/or friction fit in a fixed position adopted in the use position, along a first direction (F) and a second direction (G).

First claim

The invention claimed is:

1. A vehicle seat having a seat element which is pivotally mounted to a front base part at a secondary axis for movement from a use position into a storage position,
wherein the vehicle seat has a locking means;
wherein, in a fixing position taken up in the use position, the locking means interacts with the seat element in a first direction or a second direction in a form-fitting manner or a force-fitting manner;
wherein the locking means has a pivotable locking catch pivotally supported on a rear base part of the vehicle seat;
wherein the locking catch interacts in the fixing position in the form-fitting or the force-fitting manner with a bolt fixed to the seat element;
wherein the locking catch is configured to be pivoted in order to leave the fixing position;
wherein the vehicle seat has an articulation system that is a four-bar linkage having a first link pivotally connected to each of the front base part and the rear base part and a second link pivotally connected to each of the front base part and the rear base part for folding up the seat element; and
wherein the seat element is connected to the rear base part via a third link that forms a scissor linkage with at least a portion of the seat element, wherein, in the use position, the rear base part is fixed in a positionally fixed manner, wherein the four-bar linkage and the scissor linkage are configured such that the base part is pivoted about the secondary axis in order to take up the storage position.

2. The vehicle seat as claimed in claim 1 , wherein the vehicle seat has a backrest element, wherein the backrest element is pivotable about a primary axis relative to the seat element, wherein the locking catch can be pivoted out of the fixing position by a pivoting movement of the backrest element.

3. The vehicle seat as claimed in claim 1 , wherein the locking means has a spring element with a restoring force, wherein the locking catch can be returned into the fixing position by the restoring force of the spring element.

4. The vehicle seat as claimed in claim 1 , wherein the seat element can be pivoted about a secondary axis along a first direction of rotation into the use position, wherein the locking catch can be pivoted along a second direction of rotation into the fixing position, wherein the first direction of rotation coincides with the second direction of rotation.

5. The vehicle seat as claimed in claim 1 , wherein the locking means has a stop, wherein, in the use position, the stop is arranged together with a part of the seat element in the form-fitting manner along the second direction.

6. The vehicle seat as claimed in claim 1 , wherein the articulation system consists of a first link and a second link for folding up the seat element.

7. The vehicle seat as claimed in claim 2 , wherein the backrest element is pivotally coupled to the rear base part.
