A device for adjusting parts which can move in relation to each other includes: a driveable threaded hollow spindle with inner and outer threads increasing in opposing directions; an inner spindle cooperating with the inner threads and connected to a first fixing device to secure the device to one of the moveable parts; and a propulsive tube cooperating with the outer threads via an outer nut. The propulsive tube is connected to a second fixing device enabling fixation on one of the parts which can move in relation to each other. The threaded hollow spindle may be mounted in a rotationally fixed and longitudinally displaceable manner on a catch device which can be rotationally driven around the axis of the hollow spindle.

Device for adjusting parts which can move in relation to each other

The invention relates to an assembly for adjusting mobile elements of furniture, comprising a motor, a control circuit which is provided with push-button switches, a current supply circuit, a mains connection, a mains supply circuit, a mains isolating relay and an auxiliary current source. The aim of the invention is to construct said assembly in a more cost-effective manner whilst at the same time retaining a safety isolation from the mains. To achieve this, the first push-button switch forms a direct electric circuit with the motor and the control input of the isolating relay is connected in parallel to the motor, or is connected to the latter via a Graetz bridge.

Assembly for adjusting mobile elements of furniture

A drive mechanism for adjusting parts in furniture for sitting and lying down includes parts activated via a shaft being provided with a control lever. Adjusting mechanisms which can be driven by an electromotor are provided for driving purposes. The invention provides a drive mechanism which is compact especially with the shafts arranged close to each other. An adjusting mechanism is positioned so that the longitudinal side facing away from the shafts is opposite the longitudinal side of the other adjusting mechanism facing the shafts.

Drive for adjusting parts of seating and reclining furniture

The invention relates to a drive for adjustable parts of recliners or beds, comprising a multi-part housing, at least partly sealed off against the outside, in which electrical drive components, such as an electric motor, and mechanical drive components, such as a linkage, are located, where at least all the electrical drive components are located in the sealed section of the housing and in which the mechanically movable components leading out of the sealed housing section are sealed off against the wall of the housing section by means of a seal. The purpose of the invention is to create a drive for adjustable parts of recliners or beds which offers sufficient safety when used in damp or wet environments. The invention is characterized in that the seal (19) is of one-piece design and includes a first sealing element (20) for sealing the housing, and a second sealing element (21) for sealing the feed-through (18), where the first sealing element (20) is designed as a toroidal sealing ring and the two sealing elements (20; 21) essentially lie in one plane when not assembled, and that the second sealing element (21) can be rotated in relation to this plane.
