The invention relates to the furniture industry, in particular for the production of furniture fittings and touches the mechanism of transformation of upholstered furniture. The technical result of the claimed utility model "means the transformation of the sofa bed" is: 1. A more rigid and robust design transformation means for the sofa bed. 2. More convenient when using the sofa bed. 3. Easy to operate sofa beds. The technical result of the claimed utility model transtransformatsii means for a sofa bed is attained in that in comparison with the utility model taken as the prototype agent transformation for a sofa bed comprising a divan frame with sidewalls, transformation mechanism, made of metallic tubular members, comprising the withdrawable frame, with disposed in its front part supports rolling elements and mounted thereon, at least one additional soft element hinged lever mechanism configured possibility NOSTA lifting of at least one soft element, sidewalls, fastened between a rear, at least one rear transverse element-holder plate for mounting a soft member, in the inventive utility model, said withdrawable frame transformation mechanism is configured from the square tube and located inside the sofa frame and its said side wall formed into a frame welded of said two square pipes, curved area, and further fastened, spaced front and rear top from above and below zu sidewalls of said transverse elements withdrawable frame is provided with uprights, connecting said tubular angles between themselves and the additional supports rolling element mounted on said bottom square pipes located under Stoics bottom rear of the sidewall frame and forming with the front of said support rolling said withdrawable frame, wherein said lever mechanism is pivotally mounted on the underside of the square tube frame sidewall and configured to lift and two of said soft coup their elements and install them in a single plane at the level of the surface of the sofa seat when unfolded transformation mechanism, and transformation mechanism is provided with the rotation mechanism mounted to the upper square tube of said frame sidewalls, and synchronizer work transformable mechanism in the folded and unfolded positions, said synchronizer work transformable mechanism is designed as a reaction rod connected to said rotation mechanism on which are fixed the flanged wheels, sun tavlennye in longitudinal guides of said couch frame, wherein the jet thrust is adapted to synchronization of the vertical rotation mechanism in horizontal position when it is moved to the extreme forward position by said longitudinal guide couch frame and fixing the withdrawable frame in the given point, wherein the withdrawable frame is provided with a lateral wheel bearings mounted in the rear of the withdrawable frame, with its alignment during driving on the inside surface of said b okovin sofa frame.
