Abstract
An electromotive linear drive in the form of a dual drive adjust movably mounted parts of reclining and seating furniture. Two threaded spindles () driven by a worm gear and which are arranged one behind the other and flush with one another for displacing a lifting element. Bearings are provided at both ends of each threaded spindle (). The bearings are designed as roller bearings () having an inner ring () and an outer ring (). The aim of the invention is to design an electromotive dual drive in such a way that a short overall length is achieved and that the stability of the structure is increased. Said aim is achieved by arranging an abutment between both roller bearings (), which accommodate the spindle ends, on which the roller bearings are supported on from both sides.
