Abstract
The invention relates to a double drive, for adjusting parts of a piece of furniture, in particular, parts of a slatted bed base. Said double drive consists of two linear drives (2, 3) which each comprise an electric motor with a transmission (5), a shaft (6), coupled thereto, a nut (7), guided by said shaft and a contact surface (8), arranged on the nut (7) or on a sliding part, linked thereto, whereby a control lever (9), cooperating with the part of the piece of furniture to be adjusted, abuts against said surface. The electric motors and transmissions (5) are arranged between the contact surfaces (8) and the normal to the contact surfaces (8) extends from the electric motors and transmissions (5). In order to provide a double drive which is as compact as possible, the contact surfaces (8) are arranged along the shafts (6) laterally and on the longitudinal extension of the shafts (6) in each position of the nuts (7), both linear drives (2, 3) are housed in a common housing (1) and the transmissions (5), the shafts (6) and the nuts (7) or sliding parts, guided by said shafts, are mounted in retaining devices which are integrally moulded on said housing (1).
