Abstract (en)

The invention relates to a counterbalancer for the opening and closing mechanism of a sofa bed (10), wherein the sofa bed (10) comprises a frame (1) provided with an armrest (2), as well as a seat portion (20) including a foot section (7) and a middle section (6), which are connected to each other rotatably in a vertical plane by way of a hinge or the like and which are connected to the frame (1) rotatably in a vertical plane by means of the sofa bed opening and closing mechanism, by linking the middle section (6) of the seat portion (20) rotatably to a center of rotation (C) of the armrest (2) of the sofa bed frame (1) in such a way that the seat portion (20) is on the one hand capable of being set in a seating configuration (A), in which its middle section (6) has been folded underneath the foot section (7), and on the other hand to an opened position (B) or a bed configuration, in which the foot section (7) and the middle section (6) are at the same level. In the present invention the sofa bed opening and closing mechanism comprises at least one torsion spring (11), which is arranged in connection with the center of rotation (C) of the armrest (2) of the frame (1) by connecting a first end of the torsion spring to said center of rotation (C1) of the armrest and a second end thereof to a respective center of rotation (C2) of the middle section, such that said torsion spring (11) is in a rest condition once the middle section (6) of the seat portion (20) has pivoted to an upright position and in a stressed condition as the foot section (7) and the middle section (6) are in the seating configuration (A) or in the opened position (B).
