Electric motor furniture drive for adjusting parts of a piece of furniture relative to one another has a drive unit which has at least one electric motor and is in drive connection with at least one tensioning unit. Furniture drive has a base body which is preferably configured as a housing and is accommodated in or on the tensioning unit. At least two Bowden cables are operatively associated with each tensioning unit, traction cables of Bowden cables being in operative connection with associated tensioning unit. Traction cables are guided or guidable to tensioning unit(s) through at least one recess in the housing. The sheathings of the Bowden cables are fixed or fixable to the base body.

Support device, which is adjustable by an electric motor, for cushioning of a piece of furniture for sitting and/or lying on has a first support part, and a second support part pivotable about a pivot axis, between which a third support part is provided. Support device has an electric motor drive which has an adjusting element connected in a force-transmitting manner to the second support part by an actuating element for pivoting second support part. Actuating element has a rod-like configuration, by which the adjusting element is guided in a linearly displaceable manner in guide formed on third support part. Actuating element engages with second support part for pivoting the second support part eccentrically relative to pivot axis.

Support device which is adjustable by an electric motor

Support device, adjustable by electric motor, for supporting cushioning of a piece of furniture for sitting or lying on, in particular a bed mattress, has base body with first adjustable support part, in particular pivotable, relative to second support part. Electric motor adjusting device adjusts first support part, and has first and second adjusting unit provided on opposite longitudinal sides of base body. Rotationally supported component of first adjusting unit is connected, rotationally fixed, to similar component of second adjusting unit by a connecting shaft, and axial ends of connecting shaft engage in recesses in rotatably supported components. Connecting shaft is axially movable between a first position in which rotatably supported components are connected rotationally fixedly by connecting shaft, and a second position in which one end of the connecting shaft is released from recess, and connecting shaft is pretensioned in first position by a spring.

A device for steering a vehicle, particularly a helicopter or even a simulator, comprising a handgrip that can be moved in a manner that is linear to the drive of a drive device, particularly the power unit or motor. The linear motion of the handgrip is coupled with a rotational motion of a drive element.

Device for steering a vehicle

The invention relates to a device for controlling an engine, in particular of an aircraft. The device has at least one throttle and a regulating device for additionally controlling the throttle automatically. A displacement of the throttle is transmitted permanently, in a direct or indirect manner to a position sensor.

Device for controlling an engine

A device for converting rotational movement into axial movement includes planetary rollers driven by a drive shaft projecting from a drive device and maintained peripherally at a same distance, in addition to a push body axially displaced by the planetary rollers. These planetary rollers are peripherally fixed on a support which is driven around the axis thereof, the rollers being rotationally mounted and provided with peripheral grooves or threaded grooves; the support is connected in a fixed manner to the drive shaft rotating around its axis; the planetary rollers engage in at least one thread-like groove of the push body that is displaced along the axis of the support by means of their peripheral grooves or threaded grooves. The support drives the planetary rollers; the push body is embodied as a hollow body encompassing the planetary rollers; a bearing body that has peripheral bearing grooves or threaded grooves and that can rotate independently around its axis relative to the drive shafts and concentrically inside the planetary rollers is provided in the center of the support.

Device for converting rotational movement into axial movement

The invention relates to a device for controlling an apparatus, for example an aircraft, an aircraft simulator, a robot or the like. Said device comprises a handle which can be rotated about two axes (A, B) that are perpendicular to one another. The handle pivots about a fulcrum (P) which substantially corresponds to a point of intersection (S) of the axes (A, B).
