Definitions

  • the invention / innovation relates to seating furniture with the features of the preamble of claim 1.
  • a chair has become known from DE-GM 83 07 879.7, which i. w. consists of a shin contact surface and a seat contact surface, which are rotatably arranged on a frame in mutual mechanical connection.
  • the frame consists of a base with rotatably attached rollers, from the center of which protrudes a central column containing a gas spring.
  • the upper end of the center column is attached to a sloping downward support, at the lower end of which there is the shin contact surface and at the upper end of which there is the buttock contact surface.
  • the invention / innovation is based on the object of developing seating with the features of the preamble of claim 1 in such a way that it also enables people of the most varied body types to have an ergonomically correct and permanently comfortable sitting position.
  • This object is achieved according to the characterizing part of claim 1 in that the shin contact surface and buttock contact surface are adjustable relative to one another.
  • the shin contact surface and buttock contact surface are adjustable relative to one another.
  • the height of the seat contact surface is adjustable relative to the shin contact surface. This makes it possible to vary the flexion angle of the knee joint, so that tension in the thigh-knee area can also be avoided over longer periods of time.
  • Claim 3 makes it possible, in particular, to move the cushion covering the buttock contact surface more or less into the thigh area of the seated person, a possibility of variation which suits the blood flow to the seated person in the seat area.
  • Claims 6, 7 and 8 aim for easy handling of the adjustment with a large adjustment range.
  • relatively long gas springs can be used to adjust the seating position due to the gas spring holder projecting downward from the shin support bracket.
  • Claim 9 results in an overall compact and closed design of the entire adjustment mechanism of the chair.
  • the V-shaped design of the lower edges of the buttocks support bracket form an obtuse angle, which is located in the area of the gas springs. This effectively covers parts that can cause injuries when reaching in and adjusting them, while at the same time ensuring a high load-bearing capacity of the buttock support.
  • Claim 11 avoids an excessively steep position of the buttock contact surface, which would disadvantageously result in the buttocks slipping off the associated wearer and overloading the knees.
  • the floor support frame By designing the floor support frame from only one tube, which is curved in a circle or like a circle, and with one of its ends rising upwards in a spiral or screw shape, the disturbing, radially outward-pointing struts of conventional bases are avoided, in which the position of the base iw fixed feet of the seated under the buttocks in chairs can easily get caught according to the prior art.
  • the tube forming the base frame lies flat on the floor, so that there is no fear of the feet of the seated person getting caught.
  • the chair By slightly relieving the buttocks, the chair can kneel on carpets and the like. The like can be easily moved by slipping so that conspicuous rotating roller constructions can be omitted. Stabilizing measures result from claim 16. Claims 17 to 19 aim at a relatively simple overall mobility of the chair.
  • the seating furniture designated as a whole by 10, has a shin contact surface 12 and a seat contact surface 14, which are rotatably fastened on a floor support frame 16 in a mutual mechanical connection.
  • Shin contact surface 12 and buttock contact surface 14 can be adjusted relative to one another by means of an adjustment device, generally designated 18, whereby adjustability is understood to mean that the height H in relation to the respective upper edge of the upholstery 20, 22 by the adjustment device 18a and the seat depth T in relation to the relative distance between the two upholstery by an adjustment device 18b can be adjusted.
  • the buttock support surface 14 is fastened to a buttock support 24 which is fastened to the shin support 28 via a joint 26, which in turn is connected to the floor support frame 16 via a swivel joint 30, the protrusion angle 32 of the shin support 28 being constant.
  • the height is adjusted by adjusting the length of a gas spring 34, which can be operated using a handle 36.
  • the gas spring 34 is attached with its fixed end 38 to a gas spring holder 40 which projects downward from the upper end of the shin support bracket 28 in order to displace the fixed end 38 of the gas spring 34 so far that relatively long gas springs with a large stroke can be used.
  • the movement end 42 of the gas spring 34 is connected to the seat support 24 via a rotary bearing.
  • a slide-like displacement mechanism is provided, which can be adjusted via the handle 46.
  • actuating the handles 36 and 46 a variety of different sitting positions can be set and locked.
  • the buttock support 24 is designed as a box which is open at the bottom and has a U-shaped cross section which engages over the shin support 28 from above.
  • the lower edges 48, 50 of the seat support 24 are V-shaped and form an obtuse angle, which is arranged in the area of the gas spring 34.
  • the seat plane of the seat area 14 and the upper side 52 of the seat area close Carrier 24 at an acute angle to each other, the displacement of the buttocks area takes place iw in the seat plane.
  • the floor support frame 16 consists of only one tube, which is partially circular or like a circle and with one of its ends 54 rises spirally or helically upwards, with the rotary bearing 30 being attached to the upwardly pointing end section.
  • the rising pipe section merges into a section 56 lying on the floor and pointing inwards with respect to the ring-like section of the floor support frame 16.
  • the ring-like section 58 of the frame 16 is bent pentagonally.
  • a carpet sliding layer is provided on the underside 60 of the frame 16, but rolling elements (not shown in more detail) can also be fastened in / on the floor support frame 16.
