Abstract
A furniture item includes a fixed first structure, a second structure, and a drive assembly for moving the second structure in relation to the first structure between predefined target positions. The drive assembly has at least two servo drives. An adjustment mechanism is provided for maintaining the second structure in desired alignment with the first structure and includes a control unit for controlling operation of the servo drives, and first and second signal transducer assemblies which are operatively connected to the control unit, wherein one signal transducer assembly interacts with one servo drive, and the other signal transducer assembly interacts with the other servo drives. So long as a movement to any one of the target positions by the second structure in relation to the first structure is accompanied by a simultaneous activation of the first and second signal transducers assemblies, the second structure is in proper alignment to the first structure. When the second structure deviates from the target position, the control unit manipulates operation of one of the servo drives to adjust the movement of the second structure.
