Definitions

  • the present invention relates to a chair, in particular an office swivel chair, with a height-adjustable seat surface and backrest which is adjustable in inclination, which is articulated in the plane of the seat surface in such a way that there is a fixed area for the thigh support and a swiveling area for the buttock results.
  • the upholstery of the seat extends from the front edge beyond the swivel axis.
  • the entire chair mechanism is located below the seat. Both the height and the inclination adjustment are realized by means of springs arranged in the frame, preferably gas springs.
  • gas springs are actuated by adjusting levers positioned under the seat, to which the user has access while seated.
  • the principle of dividing the seat into a fixed thigh pad and a swiveling seat pad that merges into the backrest is known from CH-A-568 738.
  • the subdivision is realized with hinge links, which are arranged in the side parts of the support frame.
  • CH-A-582 498 discloses a chair of the relevant type. However, this construction is also limited to the swiveling of the backrest connected to the seat cover, whereby it is additionally proposed to cover the seat surface beyond the swivel axis up to the rear part of the frame.
  • a gas spring is used for the inclination adjustment; however, there is no possibility of height adjustment, an integrated, complete adjusting mechanism as well as a frame construction and upholstery covering that are adequate for today's production requirements and aesthetic demands.
  • the invention is therefore based on the object of providing an improved frame structure and a combined actuating mechanism for a chair with a pivot axis running over the seat surface, which enables all modern functions.
  • the basic structure of the chair mechanism should be as inexpensive, reliable, low-service and easy to use.
  • the adjustment mechanism to be proposed should be integrated into the chair as a compact construction.
  • the upholstery cover in functional interaction with the frame structure deserves special value, i.e. rational and cost-efficient production and assembly in series production while at the same time meeting today's creative aesthetic demands.
  • the seat support of the chair frame is placed on the conical tip of a gas spring which is arranged centrally and vertically in a known base frame - this is provided for the height adjustment and is referred to below as the gas spring.
  • the gas spring for tilt adjustment - hereinafter referred to as tilt gas spring - is articulated on the seat support, which is articulated on the other hand on the back support.
  • the back support is articulated on the seat support within the swivel axis running above the seat surface and receives the bow-shaped back tensioner.
  • the diametrically opposed control levers for the height and inclination gas springs are located below the seat support.
  • the back tensioner and two strip-shaped seat tensioners can be inserted into the upholstery cover, the first being attached to the back support and the last to the seat support.
  • the upholstery cover which extends from the seat over the cross member of the back support to the back tensioner, has an overhang in the area of the cross member, which is wrapped around and fixed to the cross member.
  • a relatively simple, compact actuating mechanism that is integrated into the frame structure that is advantageous for attaching the cushion cover is now available.
  • the entire chair can be manufactured in large quantities at efficient manufacturing costs thanks to the functionally optimized construction and the rational assembly achieved.
  • the actuating mechanism ensures a long service life, allows uncomplicated service and offers the user all the advantages of modern seating furniture, including an ergonomic adjustment of the seat cover and backrest when the user's posture changes.
  • the constructive features result in a chair that is aesthetically demanding due to its simplicity and with the least possible material expenditure.
  • Figure 1A the entire chair in perspective view
  • Figure 1B the chair according to Figure 1A in side view
  • Figure 2A the frame construction of the chair without upholstery

  • the chair consists of the star-shaped base frame 1, the seat support 2, the back support 3, the back tensioner 4, the actuating mechanism 5, the vertical gas spring 6, the tilt gas spring 7 and the cushion cover 8.
  • Extending from the base frame 1 is a centrally arranged, vertically rising center column 10, in which the height gas spring 6 is inserted for the height adjustment.
  • the seat support 2 is attached to the upper conical end of the extendable piston rod 60 of the vertical gas spring 6.
  • the seat support 2, the back support 3 and the back tensioner 4 are covered with the one-piece cushion cover 8.
  • the inclined gas spring 7 is mounted in the center of rotation in the center of rotation D1.
  • the inclination gas spring 7 is articulated in the middle on the cross member 30 of the back support 3, as a result of which the axis of rotation D2 is created here.
  • Two vertical supports 31 and two practically right-angled horizontal arms 32 extend from the cross member 30 in ascending order, resulting in a one-piece back support 3.
  • the arms 32 are connected in hinge connections V to the seat support 2, so that here the main axis of rotation D is formed, about which the back support 3 can be pivoted as a whole.
  • the area between the main axis of rotation D and the cross member 30 represents the seat pad G.
  • the bow-shaped back tensioner 4 is fastened to the supports 31.
  • the one-piece, massive seat support 2 essentially consists of a bow part 20 which is bent open at the top, each with a right-angled outside and towards the front pointing support strip 21, on which the arms 32 in the hinge connections V attach at the rear. There is an opening 200 in the center of the bottom of the bracket part 20. Below the bracket part 20 and partially embedded in it, the opposing shift levers 16, 17 for the vertical gas spring 6 and the tilt gas spring 7 are arranged.
  • FIGS. 2B and 2C there are screw holes 210, 211 in pairs in the support strips 21 in order to fasten the linear seat clamps 22 and, if appropriate, the armrests 9 to be attached. There are therefore screw holes 220 on the seat clamps 22, which correspond to the screw holes 211 in the support strips. The one at the bottom of the
