Supported by the formed support surface and pivoting the pivot axis, the inclination of the first part relative to the second part and / or the spacing of the first part relative to the second part can be adjusted. ing.

  The furniture drive device according to the present invention is used, for example, to adjust the inclination of the seat relative to the base body of the easy chair, whereby the pivot axis is supported on the support surface via the support member or members. If the swivel axis is swung based on the fact that the swivel axis is supported, the vertical spacing of the swivel axis with respect to the support surface changes, so that the inclination of the seat portion is adjusted or the spacing of the seat portion with respect to the support surface And eventually its height is adjusted.

  According to the present invention, for example, a single pivot is provided, and this pivot is supported on one end of the seat, whereas the other end of the seat is a stationary pivot. With the furniture drive according to the invention, the inclination of the seat relative to the support surface and thus to the base body of the easy chair can be adjusted.

For example, it is suitable for adjusting the parts of the ladder relative to one another. The furniture drive according to the invention is also particularly suitable for adjusting chair furniture, in particular easy chair parts, relative to one another.

  Basically, according to the invention, in order to adjust the inclination of the first part of the furniture relative to the second part of the furniture and / or the spacing of the first part relative to the second part. Only one pivot axis is provided. However, according to a very advantageous embodiment of the invention, there is provided another (second) pivot axis which is pivotally supported on the first part, spaced parallel to the pivot axis. A pivot drive device corresponding to the pivot shaft and provided with at least one other support member operatively connected to the other pivot shaft, the second support member being a second part of the furniture. Of the first part relative to the second part and / or of the first part relative to the second part by pivoting another pivot axis. The interval is adjustable. According to this embodiment, various adjustability can be obtained in a simple manner.

  The furniture drive device according to the invention is used, for example, to adjust the seat of an easy chair, and in the initial position, the two pivots have the same vertical spacing with respect to their support surfaces. The turning of the turning shaft is performed as follows. That is, the swivel axis is swiveled so that the vertical spacing of the swivel axis relative to each support surface is increased by the same amount, thereby adjusting the distance and thus the height of the seat relative to the support surface. Is called. In this case, the inclination of the seat is maintained unchanged. One pivot is swiveled, thereby increasing or decreasing the vertical spacing of this one pivot relative to the associated support surface, whereas the other pivot is not pivoted and the associated support surface The vertical spacing of this other pivot axis with respect to is kept the same so that the inclination of the seat is adjusted. In contrast, when the pivot axis is increased or decreased in the vertical distance between the two pivot axes relative to the respective support surface, the inclination of the seat is adjusted.
