A vehicle seat ( 100, 200 ), transferable from a use position into a non-use position, includes a seat part ( 120, 220 ), a backrest ( 110, 210 ), and a base ( 140, 240 ). A front rocker ( 160, 260 ) is articulated via a first joint (I) on the base/adapter ( 150, 250 ) fixed to the base, and is articulated via a second joint (II) on the seat part with limited displaceability. A rear rocker ( 170, 270 ) is articulated via a third joint (III) on the base/adapter fixed to the base and is articulated via a fourth joint (IV) on the seat part. A locking device ( 162, 262 ) locks the first joint, the second joint or the fourth joint to lock the front rocker about the first joint. A fifth joint (V) pivotably connects the backrest to the rear rocker. A pivoting movement of the backrest about the fifth joint can be locked.
