Abstract: An electromotive linear drive unit comprising a housing, a motor pot, a connection piece, a power supply cable, a deployable lifting tube, and a fixed flanged tube is designed in such a way that it can be made at a low cost while being easier to assemble than previously known embodiments thereof. In accordance with the invention, at least the connection zones of the housing (11) to the motor pot (12) and the attachment part (13) are configured in a cylindrical manner while the connection zone are formed by means of a rotary motion of the housing (11) and/or the motor pot (12) and/or the attachment part (13) in a radial direction. The connection zones are configured form-fittingly in an axial direction. This type of connection is realized by means of meshing threads. The linear drive according to the invention is particularly suitable for driving the adjustable components of a slatted frame or armchair.

Abstract: The invention relates to an electromotive linear drive (10) for adjustable components of furniture. The electromotive linear drive is constructed in such a manner that the full function is guaranteed, for the smallest possible dimensions and for the smallest possible number of components. According to the invention, the output element of the rotation speed reduction gear (27, 28), is a toothed wheel or worm wheel (28) provided with a centrically inner threaded bore. The actuator is an adjusting spindle (29) which is in contact with the toothed wheel or the worm wheel (28) and prevented form rotating and can only move in the spindle's longitudinal direction. The housing (11) has recesses which are covered by a closing element (16), with an axis of the furniture arranged in the recesses. The inventive electromotive linear drive (10) is particularly suitable for the adjustable elements of a slatted frame.
