Definitions

  • the invention relates to a chair with a seat support on which a horizontally directed rearward and upwardly bent band spring is firmly clamped on one side, on which a pivotally mounted seat plate is supported and on which a backrest is held.
  • a support for the band spring is mounted on the seat support and can be displaced parallel to the part of the band spring adjacent to the clamping point at different distances from the clamping point.
  • a band spring can be freely deformed outside the clamping point, so that the entire band spring length is available for spring movement from the clamping point.
  • the provision of a support for the band spring limits this possibility of movement of the band spring, in the area between the clamping point and the support the spring remains approximately undeformed, ie the effective length of the freely deformable area of the spring is restricted.
  • the effective spring length is varied by adjusting the distance between the clamping point on the one hand and the support on the other hand, so that the stiffness of the spring is simultaneously adjusted in this way. This adjustment can take place in stages or continuously.
  • the support is a shaft which is mounted on the seat support in guides extending parallel to the band spring.
  • These guides can be elongated holes, for example.
  • the band spring consists of a fiber composite material and that its rigidity varies over the length of the band spring.
  • the stiffness of the band spring can be varied in the individual areas by different measures that are used alone or in conjunction with one another, for example changing the cross section by means of different width or thickness, changing the fiber content or the fiber orientations in the composite material or use several layers with different stiffness properties, which are connected to a laminate.
  • the support can be removed so far from the clamping point that the horizontally rearwardly directed part of the band spring is supported in an essentially non-displaceable manner when the support is completely displaced to the rear.
  • the chair shown in the drawing comprises a seat support 1 which is held on a foot, not shown.
  • the seat support ends at its upper end in a substantially horizontal arm 2, which has a holder 3 for a band spring 4 at its front end. This extends from the holder 3 essentially parallel to the upper edge of the arm 3 to an arcuate region 5 which is adjoined by a section 6 which is directed essentially vertically upwards.
  • a backrest 7 shown in dash-dotted lines in the drawing is held on this.
  • a seat plate 8 is pivotally mounted above the holder 3, which in turn consists of two partial plates, namely a front partial plate 9 and a rear partial plate 10. Both partial plates 9 and 10 are pivotally connected to one another along their edges.
  • the supports are chosen so that when the band spring is undeformed, the front sub-plate 9 forms a small angle with the seat support 1, which is of the order of a few degrees, while the rear sub-plate 10 pivots upward relative to the seat support 1 and the front sub-plate 9 is, for example with an angle of the order of magnitude of maximum 15 °. This undeformed position is shown in the drawing.
  • elongated hole guides 16 are provided which run parallel to the band spring 4 and in which a shaft 17 can be displaced in the direction of the double arrow A.
  • this shaft 17 can be fixed in various positions along the slot guide 16.
  • the shaft can be displaceable either step by step or continuously and can be fixed in any position along the displacement path.
  • the fixing can take place, for example, by means of a clamping mechanism known per se; on the other hand, it would also be possible to achieve a fixing automatically by loading the shaft via the supported band spring.
  • the elongated hole guides 16 and the shaft 17 are dimensioned such that the shaft 17 abuts and supports the underside of the band spring 4, depending on the position of the shaft 17 in the elongated hole guide 16 at a different distance from the holder 3 .
  • the band spring When the chair is loaded, the weight of the user acting on the band spring 4 via the supports 11 and 12, on the one hand, and the user leaning back, acting on the free end of the band spring 4 via the backrest 7, the band spring is deformed in such a way that it bends downward in the area between the holder and the arc-shaped area 5, and it is also bent up in the arc-shaped area 5.
  • the lowering of the band spring 4 in the region between the holder 3 and the circular region 5 will vary depending on the position of the shaft 17 in the slot guide 16 with the same loads, since the freely deformable length of the band spring in this part is due to the Wave 17 is changed. This makes it possible to vary the stiffness of the band spring.
  • the shaft 17 in the cross-country skiing guide 16 can be displaced so far that the band spring 14 is supported in a region very far from the clamping point, preferably in a region immediately in front of the circular-arch-shaped region 5 In its horizontal area, the band spring is practically fixed in the uppermost position, so that it is no longer possible to lower the seat surface and the seat back, but only to elastically bend the backrest back. A quasi-locked chair is thus obtained which only allows the backrest to spring back.
  • the band spring 4 is particularly rigid in the area in front of the circular-arc-shaped area 5 and if the shaft 17 to in pushed this rigid area back. It is then not absolutely necessary to move the shaft into area 5, but a shorter displacement path into the rigid horizontal area of the band spring 14 is sufficient.
  • the band spring is between the clamping area and This rigid area is designed to be flexible and that the shaft 17 can only be displaced in this flexible area. In the position shifted furthest towards region 5, quasi-locking then takes place, in other regions a more or less free spring movement of the band spring 14 is possible.

Abstract

Afin de pouvoir régler la rigidité du ressort à bande d'une chaise comportant un support de siège auquel une extrémité d'un ressort à bande orienté horizontalement vers l'arrière et courbé vers le haut est fixée, et sur lequel s'appuie un plateau d'assise logé pivotant sur le support de siège et qui maintient par ailleurs un dossier, il est suggéré de placer un appui pour le ressort à bande sur le support de siège, ledit appui pouvant se déplacer parallèlement à la partie du ressort à bande voisine du point de fixation, et se positionner à des distances différentes, par rapport au point de fixation.
