Abstract

The invention relates to a vehicle seat having a seat part and a back part comprising a first back part and a second back arranged above the first back part in the seat height direction part, wherein the second backrest part is displaceable relative to the first backrest part by means of a displacement movement directed at least in the seat width direction, wherein in the first displacement position of the second backrest part, A mechanical interaction is created between the first backrest part and the second backrest part which ensures the first displaced position of the second backrest part and can be The force acting on the second backrest part and in the direction of said displacement movement is released.

Description

technical field [0001] The invention relates to a vehicle seat having a seat portion and a backrest portion, the backrest portion comprising a first backrest portion and a second backrest portion arranged on the first backrest portion in the seat height direction, wherein the second backrest portion is The displacement movement directed at least in the seat width direction is displaceable relative to the first backrest portion. Background technique [0002] It is known from the prior art to equip vehicle seats, such as commercial vehicle seats of tractors, construction machines or forklifts, with adjustment functions. These relate, for example, to the first part of the backrest, the second part of which is displaceable relative to the first part from an initial position to a displaced position. In order to ensure good support and thus provide sufficient relaxation for the driver of the vehicle, the support surface should always be as large as possible in all driving positio...
