Abstract: An articulated sofa bed has a compact profile while folded with the seat cushions residing at a comfortable and ergonomic height and an esthetically pleasing streamlined appearance. The sofa bed takes advantage of a deployment assembly having a support frame with swinging rear arms that, when the bed is folded, occupy a small volume within the back of the sofa. The sofa bed also takes advantage of a leg assembly that is anchored within the thickness of the bed panels so as to stack the foot and middle panels closer to each other. The deployment assembly also cooperates to position the middle and foot panels of the bed in a folded position at a low height above the floor and below the seat cushions, respectively.
Abstract: A sofa-bed includes: a frame with opposed arms; a backrest operatively connected to the frame; a seat; a subseat hinged to the seat and pivotable relative thereto; an extension-assist mechanism attached to the frame and at least one of the seat and the subseat; and a folding-assist mechanism attached to the frame and at least one of the subseat and seat. The frame, backrest, seat and subseat are configured to move between a folded position, in which the backrest is generally upright, the seat is generally horizontal, and the subseat is generally horizontal and positioned beneath the seat in a first inverted orientation, and an unfolded position, in which the backrest, subseat and seat are generally horizontal, and the subseat is positioned between the backrest and the seat in a second non-inverted orientation. The folding-assist mechanism is configured such that the sofa-bed is biased toward the folded position as the sofa-bed moves from the unfolded position toward a first intermediate position.

Abstract: A piece of furniture (1) that can be brought in a sofa/chair configuration and a bed configuration, wherein the piece of furniture is provided with a frame (2) comprising a first frame part (3) provided with a first extremity (3a), and a second extremity (3b) located opposite the first extremity (3a), a second frame part (4) being hingedly connected to the first frame part (3) at the location of the first extremity (3a) or being slideably connected to the first frame part (3), a third frame part (5) being hingedly connected to the first frame part (3) at the location of the second extremity (3b), a fourth frame part (6) being hingedly connected to the third frame part (5), wherein the central axes (4) around which the said frame parts (3, 4, 5, 6) hinge relative to each other extend parallel to each other, while, in the sofa/chair configuration, the second frame part (4) lies on the first frame part (3), the third frame part (5) forming a backrest (7) and the fourth frame part (6) taking up a locking position
Abstract: The invention relates to a seat which can be converted into a bed wherein the back of the seat (4) can be pivoted onto the same level as the seating surface (2) by means of arms (3), said arms (3) being connected on one end to the seat frame (1) and on the other end to the back of the seat (4). Said seating surface (2) is covered with a removable upholstery fabric (15) when the furniture item is in a seating position. The upholstery fabric is joined to the front under surface of the seat frame (1) on one side and is joined on the other side to the underside of the back of the seat (4). A double positioning drill (17) is arranged underneath the upholstery fabric (15), extending exclusively along the seating surface which is preferably joined to padding, and is connected thereto on the front end of the seating surface (2). As a result, a simple way of placing the drill is obtained.
Abstract: A convertible sofa-bed apparatus for use in a sofa or a bed configuration has hingedly interconnected and supported by frame members, and one or more pivotable arms or swing arms pivotally connected with frame members and with the seat cushion unit. The pivotable arms are rotatable between a back horizontal position wherein the apparatus is in its sofa configuration, and a frontward horizontal position wherein the apparatus is in its bed configuration. The pivotable arm or arms are preferably secured to a cross-bar rotatably mounted between end frame members to support the back cushion unit in either a vertical sofa configuration or a horizontal bed configuration, and the back support arms are preferably spring-biased to urge the arm toward such vertical position.
