  • Patent number: 8011034
    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.

  • Patent number: 7261367
    Abstract: A three position reclining chair having a front panel, arms, a seat cushion and a seat back, has a positioning linkage with interconnected seat support, leg support and seat back linkage groups. The seat support linkage group supports the chair seat for forward movement from the first, closed and erect position, so that initial forward movement of the seat actuates the leg support linkage for extending and rotating leg support members, to provide a second, TV position, and continued forward movement actuates the seat back positioning linkage, to rotate and incline the seat back without rearward movement of any portion thereof.
