A system with a pivotable armrest (1) and a locking aid (18), wherein the armrest (1) is coupled to a holding device (10) so as to be pivotable about a primary axis (11) and is reversibly transferable between a use position and a stowage position via a transition position. The armrest (1) is connected to a connecting element (15) for rotation therewith. The locking aid (18) is arranged on the connecting element (15). The locking aid (18) is in frictional contact with the holding device (10) at a contact point or along a contact surface. The locking aid (18) is configured in such a manner that the frictional contact between holding device (10) and locking aid (18) is greater in a transition position than in the use position and/or in the stowage position.
