Definitions

  • the invention relates to a chair with a variable for a swing-out footrest, with a body, a chassis, which is optionally rotatably mounted on a swivel base, a back, a seat part and a fold-out footrest, the seating between a sitting and lying position is pivotal What is the seat part relative to the chassis displaced and the footrest is coupled to the seat part such that it is pivoted when moving the seat part, the footrest is folded in the sitting position substantially below the seat part and folded in the lying position in front of the seat part in that the seat part is extended by the footrest.
  • a seat in which the footrest and the seat part in the side view each have an approximately L-shaped appearance and are arranged in the sitting position of the chair so to each other that the footrest is approximately parallel to the seat part and the respective short leg of the L- shaped parts at their free ends collide with such a slight gap formation that seat part and footrest together have an approximately U-shaped appearance.
  • the scissor hinge chains used for pivoting the leg rest are arranged to save space, however, is disadvantageous that the footrest is relatively short and in swung position of the footrest a large gap between the seat part and footrest is present, reducing the comfort impression of the user due to the non-continuous leg rest is.
  • a further disadvantage is that a total of six adjustment lever are required for the adjustment of the front portion of the seat part and for the adjustment of the footrest, whereby the manufacturing cost is relatively large.
  • the present invention seeks to further develop a chair of the type mentioned so that the footrest is pivoted with minimal gap formation to the seat part in the lying position and thereby a much greater length compared to that of the prior Technique known footrest.
  • the seating according to the invention has a large lying length, as due to an inventive "flat" movement curve of the footrest near the Wegteilvorderkante during a first phase of pivoting from the sitting to the lying position, the footrest has a greater length compared to the known footrest, without while touching the ground during pivoting.
  • FIGS. 1 to 3a . b show a basic form of the seat according to the invention.
  • An inventive seating 1 consists of a body and / or a swivel base 2, a chassis 5, a back part 27, a seat part 3 and a fold-out footrest 6, wherein the seating 1 between a in FIG. 1 shown sitting position and one in FIG. 2 shown lying position is pivotable.
