Definitions

  • the invention relates to a chair with a seat and backrest support which can be tilted backwards, the seat support being arranged on the knee-side seat end with a swivel joint on a support part so as to be pivotable about a horizontal axis and on the backrest-side seat end being pivotably connected to the backrest support by a swivel joint with a horizontal axis.
  • the latter is pivotally pivoted about a horizontal axis at a distance from the swivel joint of the seat support and can be inclined at a greater angle than the inclination angle of the seat support when the seat support is tilted backwards, a backrest guided on the backrest support being lowerable in accordance with the inclination of the seat support, and a chair frame suitable for such a chair.
  • the seat support and the backrest support are pivoted at one end to a support part at a distance from each around a horizontal axis, the seat part being connected at its other end to the backrest support by a swivel joint.
  • the backrest support tilts at a greater angle than the seat part, for which purpose one of the swivel joints must additionally be designed as a sliding joint or an additional connecting strap must be arranged on one of the swivel joints.
  • the greater inclination of the backrest support causes the known pull-out effect, ie the clothing of the chair user is pulled upwards when the back is inclined.
  • the reduction or elimination of the pull-out effect represents a noticeable increase in comfort, which is why one does not want to do without the sliding backrest.
  • This object is achieved according to the invention in that the displaceable backrest via a link chain with the back End of the seat part is coupled. It is thereby achieved that the space under the seat of parts remains free for the adjustment of the backrest and the links of the link chain can be made small because of the small distance between the coupling point and the backrest.
  • the invention also includes a chair frame that is particularly, but not exclusively, applicable to the chair according to the invention.
  • This chair frame is characterized in that a cantilever arm is assigned to the backrest support articulated in the swivel joint on the support part, the free end of which serves as a support bearing for a spring member, while the other support bearing is articulated on the swivel joint of the seat support on the support part or in the vicinity of the same in the support part is arranged.
  • the chair shown in Fig. 1 is supported on a support part 1, which usually represents part of a mostly mobile, only indicated foot frame 2.
  • a seat support 3 and a backrest part 4 are mounted on the support part 1, the seat support 3 having its knee-side end being pivotably mounted on the support part 1 by means of a swivel joint 5.
  • the backrest part 4 is articulated by means of a swivel joint 6 to a lever 7, which in turn is at a distance from the swivel joint by means of a further swivel joint 8.
  • joint of the seat support 3 is pivotally mounted in the support member 1.
  • the seat support 3 projects with an extension 12 beyond the swivel joint 9 on the backrest.
  • a link chain 15 is coupled by means of a swivel joint 16, which is composed of three links 17, 18, 19 which are connected to one another in an articulated manner.
  • the link 19 is connected at its free end to a slide 20 which is guided on the backrest support 4 and carries a backrest 21, shown schematically by a broken line.
  • the seat support 3 moves around the knee-side swivel joint 5 in the direction of arrow a and the backrest support 4 around the backrest-side swivel joint 9 in the arrow direction A, the inclination of the backrest support 4 being greater than that of the seat support 3.
  • the link chain 15 is adjusted so that the slider 20 moves down with the backrest 21.
  • the middle link 18 is pivotally mounted in the backrest support 4 by means of a swivel joint 22.
  • the link 18 thus forms a two-armed lever, by means of which the inclination of the link 17 is reduced when the backrest support 4 is tilted back and thus causes the slide 20 to move downward.
  • the link 19 only serves to prevent the slide 20 from jamming on its guide.
  • FIGS. 2-4 show that additional spring means or rods can be used for their actuation, as will be shown below.
  • the seat support 3 mounted in the knee-side swivel joint 5 is connected on the backrest side with a bracket 25 and two swivel joints 9, 13 to the backrest support 4, with which the backrest support 4 can be pivotably mounted on the support part 1 by means of the swivel joint 8 without one Sliding joint would have to be provided.
  • the backrest support 4 here has an arm 23 projecting from the swivel joint 8, on the free end of which the spring member 11 is supported. Further spring means are attached on the backrest side, see a tension spring 26 which is fastened on the one hand to the backrest support 4 and on the other hand to the supporting part 1. If further spring means are required, it is also possible to arrange a torsion spring in the knee-side swivel joint 5 of the seat support 3 and in the swivel joint 8.
  • the spring means always have the task of moving the chair into the normal or working position when it is relieved. It is desirable to be able to actuate the spring means 11 arranged in the knee area, in particular a gas pressure spring, so that the chair is in a certain position, e.g. to block in the reclined position. The actuation can be made easily accessible because of the location of the spring means.
  • one end of the spring means 11 is supported on a pair of tabs 30, 31, of which the tab 30 is supported on the swivel joint 9 of the two supports 3, 4 on the backrest and the tab 31 on the support part 1.
  • the spring travel of the spring means 11 can be varied.
  • a tension spring 27 is supported on the one hand on the pair of tabs 30, 31 and on the other hand on the support part 1.
  • the two supports 3, 4 are connected to one another on the backrest side by the tab 25 and are pivotably mounted on the supporting part 1 by the swivel joints 5, 8.
  • a pair of tabs 32, 33 is provided, of which the tab 32 on the backrest-side swivel 9 of the seat support 3 and the tab 33 on the swivel 8 of the backrest support 4 is pivotally mounted in the seat part 1.
  • the described chair and the described chair frames have a relatively small volume of rod parts under the seat support.
  • the "duck belly” that is unavoidable in other constructions due to the arrangement of voluminous and bulky rod parts under the seat support can be avoided in the present construction.
