a) the drive includes a linear-motion drive.
12. Supporting device according to claim 11, wherein:
a) the output element of the linear-motion drive includes a spindle nut which is held, secure against rotation and movable in a screw direction, on a threaded spindle rotatably drivable by the drive, and the spindle nut is in functional connection with a lever mechanism for pivoting the second supporting part relative to the first supporting part.
13. Supporting device according to claim 12, wherein:
a) the threaded spindle is disposed essentially parallel to a drive shaft of the linear-motion drive and is in functional connection with the linear-motion drive via gearing.
14. Supporting device according to claim 1, wherein:
a) the first supporting part is formed by a central supporting part and the second supporting part is formed by an upper body-supporting part, and a leg-supporting part is provided which is connected, jointedly and pivotably about a pivot axis essentially parallel to a pivot axis of the upper body-supporting part, to the central supporting part on a side opposite the upper body-supporting part.
15. Supporting device according to claim 14, wherein:
a) a head-supporting part is provided which is connected, jointedly and pivotably, about a pivot axis essentially parallel to a pivot axis of the upper body-supporting part, to the upper body-supporting part on a side opposite the central supporting part.

24. Supporting device according to claim 23, wherein:
This application is a continuation of Application No. PCT/EP00/13084, filed Dec. 21, 2000, which claims priority of German Application No. 199 62 541.7, filed Dec. 23, 1999, and each of which is incorporated herein by reference.
This application relates to assignee's concurrently filed application entitled “ADJUSTMENT PADDING DEVICE FOR A PIECE OF FURNITURE USED FOR SITTING AND/OR LYING UPON” (Ref. No. 7219) and assignee's concurrently filed application entitled “MOTOR ADJUSTABLE SUPPORT DEVICE FOR THE UPHOLSTERY OF A SEAT AND/OR RECLINING FURNITURE” (Ref. No. 7220).
The invention relates to a motor-driven, adjustable supporting device for the upholstery of seating and/or reclining furniture, e.g. of a mattress or of a bed, of the type having jointedly connected parts and a drive for moving the parts relative to each other.
Supporting devices of this type are generally known in the form of lath grids. Thus a lath grid is known, by way of example, through DE 195 42 321 A1, said lath grid having several supporting parts jointedly connected to one another for the support of a mattress over its surface which are pivotable relative to one another by drive means. In the known lath grid the drive means are formed by an adjustment drive whose drive housing is disposed below the actual lath grid.
FIG. 1 is a schematic perspective representation of a first embodiment of a supporting device in the form of a lath grid according to the invention wherein the laths of the lath grid are not represented;
In FIG. 1 a lath or slat grid 2 is represented which has, tandem in its longitudinal direction, supporting parts 4, 6, 8, 10, 12 to support a mattress, not represented in the drawing, over its surface.
