Definitions

  • the invention relates to a chair, in particular an armchair or sofa, with a seat and a pivotable about a pivot axis leg rest, wherein the chair between a sitting and lying position is pivotally, for which the seat is displaceable relative to a fixed frame to the rear and the leg rest such is coupled to the seat, that it is pivoted when moving backwards the seat.
  • Such seating are known and are also referred to as sitting and lying furniture. They allow an adjustment of the position between a "normal" upright sitting position and a far back, z. B. approximately horizontally oriented lying position.
  • an additional leg rest or foot rest can be swung forwards / upwards.
  • the problem is the distance between the front edge of the seat and the floor, which limits the size of the leg rest.
  • pull-out legrests are used, which are operated via scissors lever systems, Bowden cables, etc.
  • the DE 20 2006 006 678 U1 discloses a chair with a swinging lower leg support and a swing-out support extension, wherein the Lower leg support means hinged joint chains in particular near the side ends of the lower leg support hinged Scherengelenkketten from a basic position in which it forms a front panel which is disposed below the front end portion of the chair, is displaced into a comfort position in which it forms a preferably spaced from the seat part extension of the seat part wherein the support extension is coupled via articulated levers with the articulated chains of the lower leg support, so that it pivots out when adjusting the seat.
  • the DE 198 30 418 A1 discloses an armchair in which the seat member is arranged to be slidable rearwardly with respect to the underframe and is coupled to the backrest by connecting means which, when the seat member is displaced rearwardly, tilt the backrest rearwardly, the backrest engaging with the seat member and the underframe is connected by adjusting means, which can make changes in the tilt angle of the backrest, regardless of the position of the seat.
  • the footrest is coupled to the base frame and the seat so as to be swung forwards / upwards when the seat is moved.
  • the footrest is coupled to the underframe and the seat by a scissor system arranged inside behind or below the footrest. Similar to the one from the DE 296 00 282 U1 known chair a Bowden cable is provided, which is used to move the plate elements of a double plate arrangement against each other use.
  • the DE 44 30 303 A1 discloses a chair with fold-out legrest, in which the seat is pivoted when swinging the legrest up to increase the clear height under the seat part, so that the legrest can be swung despite greater length than the clear height.

  • the leg rest consists of a thigh part and a lower leg or foot part hinged to it. These are connected by coupled drive and transmission means. In an intermediate position during the unfolding process, the thigh part and the foot part form an acute angle.
  • the drive and transmission means have a coupling gear, which includes a thigh rocker, a foot pad and hiss links.
  • the thigh rocker is connected to the thigh part and hinged to a seat-mounted seat joint.
  • the Theticiankoppel is connected to the foot part and hinged to a knee joint of the thigh swing.
  • the intermediate links are connected to one another at a common joint.
  • An intermediate member is hinged to a hinge joint of the femoral and the other intermediate member is hinged to a hinge of the foot pad near the knee joint.
  • the demandingkoppel has a on the opposite side of the knee joint on the hinge joint projecting, the free end of the foot forming lever.
  • the joint joint is in both end positions under the action of a holding member in each case in a stable position.
  • the mechanism comprises a substantially fixed, linearly extendable element, which is connected to the frame and is pivotally articulated to the leg rest, and a pivotable, linear extendable element, which is fixedly connected to the leg rest and pivotable with the substantially fixed, linear extendable element is articulated.
  • the extendable elements are designed as telescopic profile rails. A portion of the substantially fixed rail is connected to the frame and the other part pivotally connected to the leg rest.
  • One part of the pivotable profile rail is accordingly pivotable with the frame and the other part, which is fixedly connected to the leg rest, is pivotable with the part of the substantially fixed profile rail connected, which is pivotally connected to the leg rest. Also, when moving the seat over a parallelogram-like lever system, the substantially fixed rail is changed in their orientation, so that a chair structure is achieved, despite the simple, stable construction a smooth and harmonious and soft pivoting of the legrest allowed (see, for Page 7).
  • From the DE 10 2006 038 736 A1 is also a chair with a seat and a swinging leg rest known, the seat is displaceable relative to a fixed frame to the rear and is hinged in the front area about setting lever and the leg rest is coupled to the seat so that they move backwards the seat is pivoted, wherein the leg rest is connected by means of a first sliding bearing on the raising levers and articulated by a second sliding bearing on the fixed frame, wherein the first slide bearing is pivotally connected to the second sliding bearing, and that the second slide bearing is designed such that their Alignment changed when panning.
