Abstract:
1. Support device, which is adjustable by an electric motor, for cushioning of a piece of furniture for one of sitting and lying on, comprising: a) a first support part, and a second support part which is pivotable about a pivot axis, and between which a third support part is provided; b) an electric motor drive which has an adjusting element that is connected in a force-transmitting manner to the second support part via an actuating element in order to pivot the second support part; c) the actuating element having a rod-like configuration, by which the adjusting element guides the actuating element in a linearly displaceable manner in a guide formed in or on the third support part; d) the actuating element engaging with the second support part in order to pivot the second support part eccentrically with respect to the pivot axis; and e) the third support part has a contact surface provided at a distance from the guide, so that, in a first kinematic phase, an active surface of the adjusting element provided at an adjacent first support part comes into contact with the actuating element and linearly displaces same and pivots the second support part eccentrically with respect to the pivot axis, and in a second kinematic phase the active surface of the adjusting element provided at the adjacent first support part comes into contact with the contact surface of the third support part and pivots the third support part about a pivot axis.
