Definitions

  • the invention relates to a chair with a seat which is supported by an underframe which can be brought to different seat heights via three or four telescopic supports which can be fixed at different heights, and to which a back support is fastened.
  • Such a chair is known from P 33.23 171.0-16. This chair is characterized by the fact that seat depth and backrest height can be adjusted at the same time.
  • the seat consists of a hard plate, which can also be tilted forward to achieve a favorable seating position.
  • Another disadvantage is that the seat is relatively hard and its ergonomically predetermined deformation can only be adjusted for a very specific spectrum of different body sizes.
  • the aim of a seat that can be tilted forward is to open the angle between the thigh and torso so that the abdomen and abdomen have enough space for circulation and movement.
  • a seating ball is used instead of a chair.
  • This seat ball is also used from a medical point of view for the therapy and convalescence of people with spinal injuries.
  • the spinal muscles are trained.
  • the so-called “saddle seat posture" in which the abdominal cavity is advantageously opened, can be adopted. Due to the strong pre-rotation of the pelvis, the spine is also raised in a lordosing form.
  • the aim of the present innovation was therefore to create a height-adjustable chair with back support, which has a flexible seat, which takes account of different seat inclinations and seating positions as well as a continuous change of posture in a structurally simple and therefore inexpensive form.
  • the base frame of the in FIG. 1 shown chair consists of a tube ring 2 bent into a closed circle, on which four telescopic supports 3 are welded in an even division of the circle almost perpendicular to the plane of the circle.
  • These telescopic supports 3 are at a slight degree to the outside, so that wobbling of the frame is restricted, especially since the telescopic supports 3 have a play due to their adjustability.
  • the telescopic supports 3 consist namely of an inner tube 8 and an outer tube 9 provided with a plurality of equally spaced bores, which can be adjusted via a known adjusting device 10 (ball snap principle) by the ball snapper of the inner tube 8 snapping into the bores of the outer tube 9.
  • the inner tubes 8 end on the bottom with standing surfaces 11, so that a sufficient contact surface is ensured.
  • the pipe ring 2 embeds a ball 1, the pipe ring 2 being about 10% smaller in diameter than that of the ball 1. In this way, there is sufficient jamming of the ball 1 on the frame without the need for additional fastening connections.
  • the ball 1 itself is a tightly air-filled plastic bubble sealed with a valve.
  • a back support bracket 4 is welded to the tubular ring 2 between two telescopic supports 3 in the center axis. This back support bracket 4 consists of a radially bent tube, which runs tangentially at a certain distance from the ball 1. This distance is chosen so that the bulging of the ball 1 is not impaired when sitting and damage to the ball is avoided.
  • a horizontally lying concave pipe section 6 is welded transversely opposite it, which is covered with a soft elastic material covering 7.
  • Pipe section 6 and material covering 7 form the back support 5.
  • the back support 5 could also be of a size, as is the case with normal office swivel chairs, in order to offer a larger back support surface.
  • the back support 5 is approximately at the level of the lumbar spine when the user is inserted.
  • the back support is used for occasional relaxation of the spine of the seated person when taking the rear sitting position, as shown in Figure 3 Figure A.
  • Figure 3 Figure B shows that the seated person spends most of their time in the front sitting position, as shown in Figure 3 Figure B.
  • Figure 3 Figure C shows the seated person in a sitting position rotated 180 ° around the body axis compared to the usual sitting posture, the back support 5 being used as an abdominal support; the back support bracket 4 is here between the legs. This sitting position also causes a brief relaxation of the spinal muscles.
  • Figure 2 shows an alternative embodiment of a telescopic support 3.
  • steerable rollers 12 are attached to the inner tubes 8, which are advantageously braked depending on the load.
  • the chair is suitable for use in the office.
  • Figure 4 shows a further embodiment of the invention, in which the back support bracket 4 also consists of an inner and an outer tube, which is held in various positions by means of a conventional clamping device, not described, so that the back support can be adjusted in height.
