Abstract

A convertible piece of upholstered furniture can be converted via motorized conversion aids from a seat function into a bed, by way of any desired number of intermediate stages, and vice versa. All movable parts can be fully stressed by a person during conversion, even when a person is sitting or lying on the piece of furniture. These changes can take place even when the piece is being used by a person, whereby each movable part of the piece of upholstered furniture can be changed by means of a motor drive having a control. The footrest and the seat part are configured so that they can move out of a base frame with their metal fittings. A lever construction arranged on the metal fitting of the footrest and a motor drive adjusts the height and angle of the footrest and moves the piece of furniture to the various positions.
