Abstract: A lumbar support device for an item of seating furniture, in particular an armchair, includes an electromotive linear drive including a guide profile and two sliding blocks movable on the guide profile in synchronism towards one another and away from one another. Each sliding block includes a spindle nut coupled by a spindle. The linear drive is coupled to an extendable support element via a lever mechanism which includes levers connecting the sliding blocks to the support element, respectively.

Abstract: The invention relates to a motorized functional fitting (2; 4) for a box-spring bed, said functional fitting comprising: a longitudinal member (2.1; 4.1) extending in a longitudinal axis of the member; a longitudinal member (2.1; 4.1) rotatably connected in an articulated manner to said longitudinal member; an articulated upright framework (2.5; 4.5); and a linear drive (2.4; 4.4) that is connected to the longitudinal member (2.1; 4.1) and acts on the upright framework (2.5; 4.5). In order to simplify the design, according to the invention: the longitudinal member (2.1; 4.1) can be fastened to the frame (6) or the center plate (8); an inner end face of the longitudinal member (2.1; 4.1) is designed to be fastened directly or indirectly to the center plate (8) or to the frame side parts (6.1; 6.2); the drive is located laterally adjacent to the longitudinal member (2.4; 4.4); the upright framework (2.5; 4.5) is rotatably connected in an articulated manner to the longitudinal member (2.1; 4.

Abstract: A drive for adjusting parts of seating and lying furniture, wherein a first furniture component is mounted moveably relative to a second furniture component, includes at least one spindle rotatable by an electric motor. An adjusting nut is carried on the spindle, is guided non-rotatably in a guide tube, and is drivable by rotation of the spindle in the axial direction of the guide tube. A lift tube is operatively connected to the adjusting nut. A first pivotal connecting device is arranged at the free end of the lift tube and may be pivotally connected to the first furniture component by way of a first hinge connection. A second pivotal connecting device is provided at the opposite end of the drive and can be fixed by way of a second hinge connection to a stationary frame portion or to a second furniture component.
