Abrégé

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.

Abrégé

The invention relates to a support device (2) which can be adjusted by an electric motor for the cushioning arrangement of an item of furniture for sitting or lying on. Said support device comprises a first support part (4) and a second support part (6) which can pivot about a pivotable axis (10), and a third support part (8) is arranged between said two other parts. Said support device (2) also comprises an electric motor drive comprising an adjusting element which can be connected in a force transmitting manner to the second support part (6) by an actuation element (26) used to pivot said second support part. According to the invention, said actuation element (26) is rod-shaped and can be guided into a guide (28), which is in or on the third support part (8), such that it can be displaced in a linear manner by means of the adjusting element, and said actuation element (26) engages with the second support part (6) in a manner eccentric to the pivotable axis (10) for pivoting the second support part (6).

Abrégé

The invention relates to a support device (2) which can be adjusted by an electric motor for the cushioning arrangement of an item of furniture for sitting or lying on. Said support device comprises a base body which comprises a first support section for supporting the head or upper body region of the person resting on said support device and a second support section for supporting the calf/leg area of the person resting on the support device. A stationary third support section is arranged between the fist support section and the second support section. The first support section and/or the second support section comprises at least three support parts (6, 8, 34 - 40) which can pivot in an articulated manner and in relation to each other about the pivotoable axes and/or in relation to the third support section, in addition to an electric motor drive for adjusting the support parts (6, 8, 34 - 40) in relation to each other. According to the invention, a separate actuation element is associated with the individual support parts (6, 8, 34 - 40) for pivoting the respective support parts (6, 8, 34 - 40). Said actuation elements are operatively connected to the drive in such a manner that at least two support parts (6, 8, 34 - 40) can be pivoted independently from each other.

Abrégé

The invention relates to a support device which can be adjusted by an electric motor, for supporting the cushioning arrangement of an item of furniture for sitting or lying on, in particular a bed mattress. Said support device comprises a base body which has a first support part which can be adjusted, in particular pivoted, in relation to a second support part, also comprising an electric motor adjusting device which is functionally connected to the first seat part for the adjustment thereof. Said adjusting device comprises a first and a second adjusting unit which are arranged on opposite longitudinal sides of the base body. A rotationally mounted component of the first adjusting unit is connected in an essentially rotationally fixed manner to the same component of the second adjusting unit by means of a connection shaft and the axial ends of the connection shaft engage in recesses on the rotationally mounted components. The connection shaft (22) can be axially displaced between a first position in which the rotationally mounted components are connected together in a secure manner by the connection shaft (22), and a second position in which one end of the connection shaft (22) is released from the recess associated therewith, and it is prestressed in the first position by spring means.
