Abstract: A massage carriage comprises a drive (1) that contains at least one motor and gearing parts, a first shaft (6) that can be moved by the drive (1) and a second shaft (7) that can be moved by the drive (1), two first arms, which are connected to the first shaft (6), can be moved by the first shaft (6) and on each of which a massage element is mounted, and two second arms, which are connected to the second shaft (7) and can be moved by the second shaft (7), one of which each acts on one of the first arms. In order to design the drive to be as compact, particularly as flat, as possible, it displays a single motor (2) with a motor shaft (3), by means of which the first and second shafts (6, 7) can each be moved via a reduction gear (4, 5).

Abstract: A massage carriage comprises a drive (1), a first shaft that can be moved by the drive (1) and a second shaft that can be moved by the drive (1), two first arms (3), which are connected to the first shaft, can be moved by the first shaft and on each of which a massage element (4) is mounted, and two second arms (6), which are connected to the second shaft and can be moved by the second shaft, one of which each acts on one of the first arms (3). To relieve the back of the person using the chair when the massage function of a massage chair is not in use, or when the backrest is moved far backwards or downwards, the length of the second arms (6), i.e. the distance between the point of connection to the second shaft and the point of action on the respective first arm (3), is adjustable.

Abstract: The invention relates to a double drive, for adjusting parts of a piece of furniture, in particular, parts of a slatted bed base. Said double drive consists of two linear drives (2, 3) which each comprise an electric motor with a transmission (5), a shaft (6), coupled thereto, a nut (7), guided by said shaft and a contact surface (8), arranged on the nut (7) or on a sliding part, linked thereto, whereby a control lever (9), cooperating with the part of the piece of furniture to be adjusted, abuts against said surface. The electric motors and transmissions (5) are arranged between the contact surfaces (8) and the normal to the contact surfaces (8) extends from the electric motors and transmissions (5).

Abstract: A massage arm (1), comprising a massage element (2) for a massage unit that can be incorporated into a massage chair or similar, is hinged on at least one shaft that can be moved by a drive in the massage unit, and has an articulated connection to the massage element (2). To achieve an improved massaging action with the massage arm and the attached massage elements, it is proposed that the articulated connection comprise a ball-and-socket joint (3).

Abstract: A massage arm (1) comprising a massage element (2) for a massage unit which can be mounted on a massage chair or other seat or other item of furniture used for seating or lying purposes, wherein the massage arm (1) is coupled to at least one shaft, which can be displaced in the massage unit by means of a drive in order to produce a first vibrating movement within a first frequency range, and is connected to the massage element (2) in an articulated manner. The massage element (2) has at least one contact surface which acts upon the body of the person receiving the massage. According to the invention, in order to achieve an improved massage effect, a vibration device (8) is provided. Said vibration device produces a second vibrating movement which is superposed on the first, said vibration movement occurring within a higher frequency range in comparison with the first.

Abstract: On a foot-controlled operating element for motor-driven items of furniture, particularly lift beds (1) and treatment couches, with a motor-driven lifting mechanism and a foot switch for operating the drive, where the drive function can be activated by exerting a load on the foot switch, provision is made, for the purpose of deactivating the drive motor of the lifting mechanism, preferably reversing the lowering movement until the operator's foot is released, for the foot switch to display at least a second switching step, which can be triggered by increasing the operating force exerted by the foot beyond the normal load value, and stops the downward movement of the item of furniture.

Abstract: The invention concerns a linear drive (1) with a linear stroke for the displacement of movably supported parts, in particular of articles of furniture, comprising a rotary spindle (2) which is driven by a motor and which at the drive output side is in screwthreaded engagement with a thrust tube (3) or a spindle nut (4) connected thereto with a female screwthread (5), wherein the thrust tube (3) is mounted non-rotatably and slidably in the housing (6) and is displaceable in the housing (6) over a stroke travel h relative to the rotary element, and a travel measuring device for measuring the stroke travel h.

Abstract: On a lift bed comprising four, telescopic lifting columns, which can be connected by a reclining-surface frame (8), as well as by head (2), foot (3) and side elements (4), provision is made, to permit simple assembly and dismantling of the head, foot and side elements, for the lifting columns to each display a slit (5.4), which is parallel to the axis and points towards the adjacent side element (4), and for the reclining-surface frame (8) and the side elements (4) to display corresponding anchoring elements (4.3) that can be inserted into the slits (5.4) in sliding fashion from above.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a safety device for furniture with at least one movable element which can be moved by a motor-driven positioning drive controlled by operating controls, particularly the head and/or foot of a base for a bed, or a seat and/or backrest element of an armchair, where the positioning of the element forms a gap in which an object or body part can become trapped as a result of the movement of the element. If a body part becomes trapped, this can lead to serious injury. Objects must also be prevented from becoming trapped, as they can cause damage to the furniture. According to the invention, at least one contact element is positioned in the gap which, when subjected to the pressure applied by an object or body part becoming trapped, closes an electric circuit which bridges a switch associated with one of the operating controls, the closing of which prevents further movement of the positioning drive.
