ABSTRACT A device for moving and/or locking relative to each other adjustable parts such as a frame of a bed or chair and a head or foot end, or a seat or back part, rotatably connected thereto, is provided with a base element which interacts with one of the parts movable relative to each other, an adjusting element or locking element which interacts with the other part, and also drive means for adjusting the adjusting element relative to the base element. The base element is an elongated section running parallel to the frame, or a part adjustable relative thereto, while the adjusting element is an arm which is movable by means of the drive means between a position in which it extends along or is accommodated in said section and a position in which it projects in said direction of movement relative to the section. According to a preferred embodiment, provision is made for an arm which can be swivelled about a fixed hinge point of the frame or the adjustable part, and which forms part of a link mechanism with two arms, of which the second arm is hinged with play to an element which can be slid relative to the frame or the adjustable part, and which second arm has a part which can interact in such a way with a control face of the sliding element that the second arm swings out of the initial position at an obtuse angle relative to the first arm, before the abovementioned play has been passed through.
