Definitions

  • the invention relates to a chair with a seat and at least one pivotable about an approximately upright pivot axis foot part, wherein the axis of rotation of the foot part is arranged in the region around a front seat and viewed in at least one view has an oblique position to the vertical.

  • the pivoting by 180 ° requires a rather complex control mechanism, and is increased impractical at a greater length of the foot due to the central axis of rotation of the laterally required pivot.
  • the object of the invention is to provide a chair of the type mentioned, which advantageously reduces a height level between the seat and foot in a swiveled end position to an ergonomically favorable level.
  • the axis of rotation seen in the front view has a significant inclination to the vertical, that this inclination of a seat edge extends downwardly inside, and that the foot part extends in an initial position obliquely from the seat edge to a floor.
  • mirror-symmetrically two such foot parts are attached to a sofa.
  • their axes of rotation are each on the side of the armrests. Due to the oblique position of the axes of rotation according to the invention in the front view, it is even possible that the foot parts do not abut one another in the middle during individual pivoting. Rather, the moving foot can immediately dip down obliquely and thus run on a different altitude track than the dormant.
  • the seat is rigidly arranged.
  • a relatively movable to the seat in particular rotatable about a transverse axis backrest is provided, and there is a linkage, which forms an operative connection between the foot part and the backrest.

This makes it possible to achieve an ergonomically favorable extension of the seat with a backrest displaced to the rear and a foot part swiveled out to the front.
  • a position of the backrest displaced to the rear and a position of the foot part pivoted out to the front constitute functional positions in the sense of the disclosure according to the invention.

  • the articulation of the axis of rotation is also located in an armrest of the seat.
  • it is formed by a seated on the axis of rotation angle lever and a control rod which extends in the armrest of this angle lever to the backrest.
  • the pivot point on the backrest has a distance from the hinge of the backrest, which is a multiple, about four to six times the lever length of the angle lever. This creates a simple, robust and injury-hazardous transmission.

This ensures that both the backrest and the footboard are moved back to their original position as soon as the person sitting on the chair gets up and moves away from the seating. Thus, the foot is pivoted back to its rest position under the seat. At the same time the backrest is moved back to its steep starting position.
