Definitions

  • the invention relates to seating, in particular a chair, with the features the preamble of claim 1.
  • Such chairs with a frame with, for example, tubular steel legs, on which a seat is preferably attached with a seat and a backrest, are known per se. They have the disadvantage that they are only for one Posture are provided.
  • the invention has for its object a seating of the aforementioned Art to train so that it adapts to different postures.
  • Another object of the seating furniture according to the invention is to adapt to brake changing posture.
  • the seat is pivotable on the frame attached so that the seat by a limited swivel angle tilts back when a person sitting on the seating leans back.
  • the Swiveling of the seat preferably a seat together with one Backrest enables both upright sitting and a comfortable, leaning back.
  • the seating furniture according to the invention supported possibility of switching between sitting upright and leaning back and any intermediate position between these two Sitting posture enables and supports movements of a seated person, which is particularly relaxing and fatigue-free when sitting for long periods Sitting ensures.
  • Damping element sets the pivoting movement of the seat, so the movement a person sitting on the seating preferably one speed-dependent resistance. This braked or cushioned swiveling behavior of the seat is considered by the seated person felt pleasant.
  • Another advantage of the damping element is that the seat after getting up suddenly not in one of its two end positions pivots, but slows down to the end position.
  • the seat can be pivoted, for example, by means of a curve of the seat on the frame can be reached when pushing the Seat on the frame increases or decreases a seat inclination.
  • the seating furniture according to the invention has a pivot axis, about which the seat is pivotally attached to the frame, the pivot angle is limited. Such a pivot bearing is inexpensive to manufacture and robust.
  • a further development of the seating furniture according to the invention has one Return spring element on the seat after getting up on the Seating person swings back into a basic position and in the Basic position holds.
  • the basic position is preferably the less or not inclined position of the seat, which is intended for an upright sitting posture.
  • the damping element has a connection with the return spring element Advantage that the seat is not catapult-like after getting up and a hitting noise causing it to spring back into its basic position, but instead slows down and moves back to the basic position without making any noise.
  • a leaf spring serves as a return spring element.
  • a leaf spring is an inexpensive spring element that is simple and can be attached in a space-saving manner to the seating furniture according to the invention.
  • a damping element occurs Rotary damper use as it is known per se and its Damping effect on friction, especially on internal friction and Flow properties of a liquid absorbed in the rotary damper is based.
  • a spring damping element Use that dampens both the pivoting movement of the seat as well due to its springy nature the seat after getting up in its Home position moved back.
  • FIG. 1 The section shown in FIG. 1, partly in schematic and simplified form, Chair 10 according to the invention has a frame 12 with four tubular steel legs 14, 16 on.
  • Each pair of front chair legs 14 is straight and stands on the floor standing chair 10 almost vertically.
  • At an upper end of the front Chair legs 14 are welded on rear chair legs 16, which are initially almost run horizontally backwards and further down in an arc.
  • left and right chair legs 14, 16 are together with a pair of flat steels 18, 20 connected, the left and right chair legs 14, 16 connecting transversely in the almost horizontally backward area with the rear legs 16 are welded.
  • Of the chair legs 14, 16 are due to the Sectional view only the two right chair legs 14, 16 visible.
  • a seat shell 22 is attached to the gesture 12 as a seat and has a seat surface 24 and one with this one-piece backrest 26. Located in Figure 1 the seat pan22 in a basic position for upright sitting, the seat 24 runs almost horizontally, it has a slight inclination to the rear and that Backrest 26 is relatively steep upwards.
  • the seat shell 22 is connected to the frame 12: the seat shell 22 is connected to a pivot fitting 32 having a pivot pin 30 with the frame 12 connected.
  • the pivot fitting 32 is the left one at a rear of the two and the right chair legs 14, 16 cross-connecting flat steels 20 welded and on the other hand on an underside of the seat 24 by means of Drawing of invisible screws attached.
  • the pivot pin 30 define a pivot axis extending transversely to the chair 10 approximately in one Center between the backrest 26 and a front edge of the seat surface 24.
  • the seat pan 22 is not one by shifting the body weight drawn, sitting on the chair 10 person to the rear, that is Lean back about the pivot axis defined by the pivot pin 30 a basic position shown in Figures 1 and 3, in which the seat 24th is almost horizontal and has only a slight inclination to the rear and in which the backrest 26 is relatively steeply upwards, in one to the rear inclined position pivotable, which is shown in Figures 2 and 4 and in which the Seat 24 and the backrest 26 a greater inclination to the rear exhibit.
  • Leaf spring 34 On the pivotable, attached to the underside of the seat 24 part of the Swivel fitting 32 is one with rivets not visible in the drawing Below the seat surface 24 extending leaf spring 34 attached.
  • This Leaf spring 34 which is straight in the undeformed state, is elastic downward bent and lies with a right-angled upward bend 36 an underside of a front, the chair legs 14, 16 cross-connecting Flat steel 18.
  • the elastically bent down, d. H. biased Leaf spring 34 exerts a torque on the seat shell 22, which this in its Figures 1 and 3 shown basic position and presses against the force Seat shell 22 by leaning back into that shown in Figures 2 and 4, after rear tilted position is pivotable.
  • Rotation damper 40 dampens the pivoting movement of the seat pan 22, he prevents in particular that the leaf spring 34 from the seat shell 22 like a catapult the reclined position swung into the basic position after one on the person sitting in the chair 10 got up.
  • the rotary damper 40 causes a braked and therefore slow and smooth swiveling movement of the Seat shell 22.
  • FIG. 1 Rotation damper and the leaf spring by a gas pressure spring damper 50 known design replaced.
  • the gas spring damper 50 is below the Seat 24 arranged at an acute angle to this.
  • a cylinder 52 of the Gas strut 50 is pivotable on the rear with that Chair legs 16 transversely connecting flat steel 20 welded part of the swivel joint 32 for the seat shell 22 articulated.
  • One in cylinder 52 axially is displaceably guided piston rod 54 of the gas spring damper 50 swiveling approximately at the level of the front, the two chair legs 16 transversely interconnecting flat steel 18 on the underside of the seat surface 24 articulated.
  • the seat surface 22 is against a force acting here as a tension spring element Gas spring damper 50 in the rearward inclined shown in Figure 5 Swiveling position.
  • the gas spring damper 50 pivots unloaded seat shell 22 as the leaf spring 34 in the only slightly inclined Home position (not shown).
  • the pivotal movement of the seat pan 22 is in damped in both directions by gas spring 50.
  • this is Design of a chair according to the invention, of which only the in Figure 5 Movement mechanics is shown in a representation corresponding to FIG. 4, in designed in the same way as the chair 10 shown in Figures 1 to 4. It in this regard, reference is made to the above statements relating to FIGS. 1 to 4.
