Furniture, particularly upholstered furniture, for transferring from a sitting position to a lying position

Claim 2

Furniture, particularly upholstered furniture, for transferring a person from a sitting position to a lying position and vice versa, comprising: a seating member that can be extracted forward out of a stationary means and forms part of a reclining surface; said seating member comprising a chassis with rolling support means, a seating frame positioned on top of said chassis and forming a covering and a backrest having two backrest members connected so that they can be swung in relation to each other and positioned substantially back-to-back in a sitting position and being positioned one after the other in a reclining position with said seating members extracted; a bottom framework; one of said backrest members being a rear backrest member hinged to said bottom framework; catch linkages on both sides of said seating frame and arranged to catch in one direction of swing; the other one of said backrest members being a front backrest member connected to said seating frame by said catch linkages; said seating frame being pivotally connected to said chassis; scissoring linkage means on both sides of said backrest and comprising a symmetrical double parallelogram connecting said two backrest members; a four-bar linkage connecting said seating frame to said chassis and having pairs of pivoting elements.

Claim 3

Furniture as defined in claim 1, including telescoping rails for guiding said seating member on said bottom framework.

Claim 4

Furniture as defined in claim 1, including a ratchet rod with ratchet teeth on said catch linkages and being operative when said seating frame and said front backrest member are folded together, said ratchet rod being inoperative when said seating frame and said front backrest member are unfolded out of a folded-up position.

Claim 5

Furniture as defined in claim 1, wherein said catch linkages have at least one catch position in which said seating frame when pivoted up is aligned down with respect to said front backrest member and stopped in another direction of swing, said seating frame when pivoted back onto said chassis being lifted by said catch linkages on said front backrest member to the same angle with respect to said bottom framework.

Claim 6

Furniture as defined in claim 1, wherein each pair of pivoting elements comprises a longer front bracket and a shorter rear bracket with pivoting points on said seating frame that are closer together than pivoting points of said brackets on said chassis.

Claim 7

Furniture as defined in claim 5, wherein said two brackets slope toward said front backrest member in a sitting position and form a converging angle with one another.

Claim 8

Furniture as defined in claim 5, wherein said catch linkages have a pivoting member connected to said seating frame, said pivoting brackets pivot on said pivoting member and forming a unit with said catch linkages; and a connecting bracket attachable to said chassis and connected to free ends of said pivoting bracket.

Claim 9

Furniture as defined in claim 1, wherein said rear backrest member is connected to said bottom framework by a hinge.

Claim 10

Furniture as defined in claim 1, wherein said rear backrest member is elongated downward and to the rear.

Claim 11

Furniture, particularly upholstered furniture, for transferring a person from a sitting position to a lying position and vice versa, comprising: a seating member that can be extracted forward out of a stationary means and forms part of a reclining surface; said seating member comprising a chassis with rolling support means, a seating frame positioned on top of said chassis and forming a covering and a backrest having two backrest members connected so that they can be swung in relation to each other and positioned substantially back-to-back in a sitting position and being positioned one after the other in a reclining position with said seating member extracted; a bottom framework; one of said backrest members being a rear backrest member hinged to said bottom framework; catch linkages on both sides of said seating frame and arranged to catch in one direction of swing; the other one of said backrest members being a front backrest member connected to said seating frame by said catch linkages; said seating frame being pivotally connected to said chassis; telescoping rails for guiding said seating member on said bottom framework; a ratchet rod with ratchet teeth on said catch linkages and being operative when said seating frame and said front backrest member are folded together, said ratchet rod being inoperative when said seating frame and said front backrest member are unfolded out of a folded-up position; said catch linkages having at least one catch position in which said seating frame when pivoted up is angled down with respect to said front backrest member and stopped in another direction of swing, said seating frame when pivoted back onto said chassis being lifted by said catch linkages on said front backrest member to the same angle with respect to said bottom framework; each pair of pivoting elements comprising a longer front bracket and a shorter rear bracket with pivoting points on said seating frame that are closer together than pivoting points of said brackets on said chassis; said two brackets sloping toward said front backrest member in a sitting position and forming a converging angle with one another; said catch linkages having a pivoting member connected to said seating frame, said pivoting brackets pivoting on said pivoting member and forming a unit with said catch linkages; a connecting bracket attachable to said chassis and connected to free ends of said pivoting bracket; said rear backrest member being connected to said bottom framework by a hinge; said rear backrest member being elongated downward and to the rear.

Claim 12

Furniture, particularly upholstered furniture, for transferring a person from a sitting position to a lying position and vice versa, comprising: a seating member that can be extracted forward out of a stationary means and forms part of a reclining surface; said seating member comprising a chassis with rolling support means, a seating frame positioned on top of said chassis and forming a covering and a backrest having two backrest members connected so that they can be swung in relation to each other and positioned substantially back-to-back in a sitting position and being positioned one after the other in a reclining position with said seating member extracted; a bottom framework; one of said backrest members being a rear backrest member hinged to said bottom framework; catch linkages on both sides of said seating frame and arranged to catch in one direction of swing; the other one of said backrest members being a front backrest member connected to said seating frame by said catch linkages; said seating frame being pivotally connected to said chassis; telescoping rails for guiding said seating member on said bottom framework; a ratchet rod with ratchet teeth on said catch linkages and being operative when said seating frame and said front backrest member are folded together, said ratchet rod being inoperative when said seating frame and said front backrest member are unfolded out of a folded-up position; said catch linkages having at least one catch position in which said seating frame when pivoted up is angled down with respect to said front backrest member and stopped in another direction of swing, said seating frame when pivoted back onto said chassis being lifted by said catch linkages on said front backrest member to the same angle with respect to said bottom framework; each pair of pivoting elements comprising a longer front bracket and a shorter rear bracket with pivoting points on said seating frame that are closer together than pivoting points of said brackets on said chassis; said two brackets sloping toward said front backrest member in a sitting position and forming a converging angle with one another; said catch linkages having a pivoting member connected to said seating frame, said pivoting brackets pivoting on said pivoting member and forming a unit with said catch linkages; a connecting bracket attachable to said chassis and connected to free ends of said pivoting bracket; said rear backrest member being connected to said bottom framework by a hinge; said rear backrest member being elongated downward and to the rear.
