Definitions

  • the invention relates to seating furniture with a front part of the seat which is pivotally attached to the base body about a transverse axis in its front region, and a rear part of the seat which is arranged pivotable relative to the front part of the seat.
  • Such a chair is known from DE-OS 28 22 574.
  • the angle between the backrest and the rear seat part surface changes when the seat inclination is adjusted, with the result that the back support relative to the pelvis is different with each inclination adjustment of the seat surface.
  • Only in a certain inclination of the seat is a desired angular position between the rear seat part on the one hand and the backrest on the other possible, and therefore only in one be the desired back support was possible.
  • the object of the present invention is to provide seating furniture which enables ergonomic adjustment of the sitting position and at the same time active support of the body in every sitting position.
  • an angled lever is pivotally mounted about a pivot bearing arranged below the front seat part, in that the rear end section of the lever is designed as a support for the rear seat part, which extends upwards at the rear is formed into a one-piece seat-pelvic support, and that a rigid arm of the rear section of the front seat part is articulated to this lever in the area below the rear seat part.
  • the rear section of the seat is shaped as a one-piece buttock-pelvic support provides constant support for the pelvis, regardless of in which angular position the rear part of the seat and thus the buttocks and pelvic support is pivoted. It is therefore possible according to the invention not only to provide the body with a feeling of security in all movements, but also to provide support that prevents tension and cramping of the back muscles and thus rapid fatigue. This pelvic support also avoids the postural damage that would otherwise occur in the long term.
  • the lever which can be designed as a wide-area plate in the direction of the pivot bearing, is pivoted, the rear seat part surface, and thus also the buttocks and pelvic support, is pivoted at the same time by the same angular amount.
  • the inclination of the front seat part surface is also adjusted by pivoting the lever.
  • this inclination adjustment of the front seat part surface takes place by a smaller angular amount than the inclination of the rear seat part surface, because the front seat part surface is not rigidly connected to the lever. Rather, only the boom rigidly connected to the rear section of the front seat part surface is articulated on the lever. When the lever is pivoted, this articulated boom is therefore moved downwards or upwards in accordance with the lever movement.
  • the front part of the seat pivots about its front area.
  • the further the pivot bearing arranged under the front seat part surface is arranged in the rear part area of the front seat part surface, and the closer the rear arm of the front seat part surface is articulated to the pivot bearing of the lever, the greater the relative change in inclination ratio between the rear seat surface and the front seat surface.
  • the desired relative change in seat inclination can be adjusted by designing these length ratios.
  • the seating furniture can be designed such that the rear edge of the front seating part surface forms a gap running across the seating furniture with the front edge of the rear seating part surface; this is expediently covered by padding.
  • the backrest is connected to the upper section of the buttocks and pelvic support, optionally rigidly or pivotable relative thereto.
  • the invention also has the advantage that it enables a continuous adjustment of the front and rear seat inclination and the back connected to the rear seat part surface. At the same time, it has the advantage that it enables the production of seating with few components and in an economical manner.
  • the adjustment mechanism is essentially arranged in a support tube.
  • a support shoe is fastened in the support tube, on which the lever is rotatably mounted.
  • the seating furniture can only be mounted on the support tube, so that no pillar is required is. Furthermore, it is also possible to arrange several such pieces of seating on a continuous tube. It is also possible in this way to easily arrange entire benches or several rows of seats with seating furniture according to the invention on these tubes. Such training has the advantage that the floor is freely accessible for cleaning. Another advantage is the considerable material savings, because not every single chair requires one or even more legs.
  • Another advantage of this arrangement of the adjustment mechanism in a tube is the fact that on the one hand the adjustment mechanism is protected and on the other hand also persons are protected from accidentally pinching fingers or the hand in the adjustment mechanism.
  • the lever can extend within the support tube substantially over the width of the Stizteil arrangements, whereby a firm support of the rear seat part surface is facilitated.
  • the seating can be biased into desired positions by spring devices.
  • one or more compression springs are arranged below the lever arm running from the pivot bearing to the rear end of the rear seat part surface.
  • the seating furniture can be pretensioned into its one end position, in which the rear end of the front seat part surface and also the rear end of the rear seat part surface assume their uppermost position.
  • the seating furniture according to the invention can be used as a rocking chair.
  • An adjusting screw is expediently provided, which enables the pressure force of the compression spring mentioned to be changed. In this way, the spring force can be adjusted in the desired manner to the weight of the person using the seating.
  • the lever is designed as a two-armed lever, the second arm of which extends essentially downward from the pivot bearing.
  • This development of the invention has the advantage that two ends of the lever can be acted upon by desired adjusting forces, so that larger adjusting forces can be exerted on the lever even with a compact design.
  • a spring is arranged in the housing, between the front part of the same and the lower end section of the second lever arm. If this spring is a compression spring, it acts in the same sense as the compression spring described above, which is arranged under the first, ie the rear lever arm within the support tube.
  • the spring arranged in the housing between the front housing section and the lower end of the second lever arm can be the only spring or in addition to that be provided before described, arranged under the first rear lever arm compression spring.
  • the spring arranged in the housing is expediently a gas spring. As long as the release lever of this gas spring cartridge is pressed in, it acts like a normal spring. In this position the chair can be used as a rocking chair.
  • a trigger mechanism for actuating the trigger lever of the gas cartridge is provided. By actuating this trigger mechanism, the trigger lever of the gas cartridge is actuated, thereby allowing the seat inclinations to be adjusted. If this release mechanism is released again, the now locked gas spring locks the seat in the set position.
  • a pivotable spring tab is provided, which is able to lock the free end of the release mechanism in its release position. In this way it is possible to use the chair as a kind of rocking chair.
  • a particularly simple to set up seating with adjustable seat and adjustable backrest is created, which is characterized in that the seat part is pivotally arranged about its front region on the housing, an angled lever which is connected to the back bar to a is arranged pivotally below the Stiz products pivotally and on this lever, in the area behind the pivot bearing, a rigid arm of the seat part is articulated.
  • the back bar connected to the lever is also pivoted.
  • the seat part is also pivoted, but by a different angle than the back bar.
  • the seat of this chair is subdivided, it consists of a front partial seat surface 18 and a rear partial seat surface 20, which are not directly connected to one another, but rather form a narrow, continuous gap 22 with one another.
  • the rear part of the seat is bent upwards in its rear area and thus forms a one-piece buttock and pelvic support.
  • the rear upper section 24 of this buttock-pelvic support supports the pelvis in particular at the level of the pelvic crest.
  • the backrest is attached to the upper end section 24 of the buttocks and pelvic support.
  • a cushion 26 is attached to the seat surfaces and the backrest.
  • FIG. 1 also shows the essential elements of the adjustment mechanism:
  • a two-armed lever which is also referred to below as a support shoe and which is described in more detail in connection with FIG. 3, is rotatably mounted about an axis of rotation 30.
  • the first, rear lever arm 32 is initially formed obliquely upwards from the axis of rotation 30, then angled downwards.
  • the second lever arm 34 he extends essentially downward from the axis of rotation 30 and somewhat to the front.
  • the rear, angled section of the first lever arm 32 is formed parallel to the rear seat part surface 20 and rigidly connected to it. By pivoting the lever 32, 34, the rear partial seat surface 20, and thus the entire seat and pelvic support 20, 24, is pivoted by the same angle as the lever 32, 34.
  • a compression spring 38 is arranged inside the support tube 16 under the first, rear lever arm 32, which compensates for the weight load of the person sitting on the chair.
  • the front seat part surface 18 is rotatably mounted on an axis 50.
  • a rigid boom 78 is attached to the rear end section of the front seat part surface 18 and is articulated at 44 to the first, rear lever arm 32.
  • the distance of the articulation point 44 to the axis of rotation 30 is considerably shorter than the distance between the articulation point 44 and the axis 50 by which the front seat part surface is pivoted when the lever 32, 34 is pivoted. Therefore, when the lever 32, 34 is pivoted clockwise in the illustration in FIG. 2, the front seat part surface is pivoted by a smaller change in angle than the rear seat part surface and the backrest 25.
  • a gas cartridge 48 is also provided, which is articulated with its rear end at 36 on the front lever arm 34 and is articulated with its front end on the axis 50, which is arranged parallel to the axis of rotation 30 and right and left at 52 on the Housing is attached.
  • Figure 3 shows a plan view of the tubular base support of the chair.
  • This main body essentially consists of the tube 16, which merges into a boom 14 in its central region, on the left in FIG. 3, in the front region of which the axis 50 is arranged at 52.
  • the gas spring 48 which is rotatably connected to the front lever 34 at its rear end at 36 and which is fastened to the axle 50 at its front end.
  • FIG. 3 This mechanism essentially consists of an angled deflection lever 58, the angle of which, in FIG 60 pushes the release plug 56 into the gas spring 48 or releases it. At the right end of the bell crank 58 you can see the operating lever 62 with which the right end of the lever 58 can be pressed down or released.
  • a seat 66 is indicated by dashed lines and is provided for receiving a compression spring which is located between the underside of the support tube 16 and the shoe to be described.
  • FIG. 4 shows a top view of a shoe 13 which essentially consists of the lever arms 32 and 34 described.
  • the part of this shoe designated in connection with FIG. 2 as the first lever 32 consists of a plate which is pivotally connected to the support tube 16 via two bearings 64.
  • the shoe has a plurality of reinforcing ribs 70, which need not be discussed in detail.
  • Figure 5 shows a section along the line 5-5 of Figure 4.
  • the receiving assembly 36 is formed in the front lever 34 as a slot into which a transverse axis of the rear end of the gas spring is inserted.
  • the shoe is rotatably attached to the support tube 16 at 64.
  • the rear end of the rigid arm 78 which is rigidly connected to the rear end of the front seat part surface 18, is pivotally attached at 74.
  • FIG. 6 shows a section along the line 5-5 of FIG. 4.
  • This part of the rear lever 32 of the shoe is rotatably connected to the support tube 16 in the bearing 64, which defines the axis of rotation 30.
  • another joint with an eye 74 is provided for articulating a rigid arm 78, which is rigidly connected to the rear end of the front seat part surface 18.
  • This rigid boom 78 is shown in FIG. 7 in a side view and in FIG. 8 in a top view.
  • the boom 78 has an elongated hole 76 at one end, while it is fastened at its other end via a plate 80 and by means of two screws 82 to the rear end of the front seat part surface 18; see. also FIG. 3.
  • a bolt 84 which extends through the eye 74 as well as through the elongated hole 76, connects the arm 78 to the shoe 13.
  • the hole 76 in the bracket 78 must be designed as an elongated hole, because when the inclination of the seat part surfaces 18 and 20 moves relative to each other and the distance between them changes.
  • This seat depth ver position takes place by shifting the front seat part surface 18 relative to the rear seat part surface 20th
  • the elongated hole 76 in the arm 78 is dimensioned accordingly long.
  • the front fastening of the front seat part surface 18 can also be displaced for this purpose, which is described in more detail with reference to FIG. 3.
  • an aluminum part 86 is fastened with its claws 88 projecting towards the housing 14.
  • This aluminum part 86 which forms, as it were, an extension of the housing 14, has slots 90 which serve to hold and guide a slide 92, which in turn has downwardly projecting bolts which are guided in the slots 90.
  • This slide plate 92 is rigidly screwed to the front seat surface 18.
  • the front seat part surface 18 also shifts to the right and thus to the rear seat partial area 20 towards, the gap between the front part of the seat part and the rear part of the seat area being reduced, and thus the seat depth being reduced.
  • the clamping screw 94 is used to lock the chair in the desired seat depth setting.
  • FIG. 9 shows a side view of an embodiment of the invention, in which the seat is not divided, but rather is designed as a continuous seat shell. Parts of this figure which are identical to those of the previously described figures have the same reference numerals.
  • FIG. 8 In the simplified illustration in FIG. 8, one can see a seat shell 102 which is pulled up in its rear region 103, so that it simultaneously forms the seat surface and pelvic support.
  • This seat shell 102 is rotatably supported about an axis in its front region.
  • a two-armed lever 32, 34 which merges into a back bar 104 at its rear end region, is pivotably mounted in a pivot bearing 64.
  • a boom 106 is rigidly connected at one end to the seat shell 102, while it is pivotally connected to the other end region thereof via an elongated hole (108) and by means of a pin in an eye 109 of the lever 32, 34. This connection point lies behind that of the pivot bearing 64 and thus behind the axis of rotation 30.
  • FIG. 9 A position of the chair is shown in FIG. 9 by solid lines. Another position this chair is shown by dashed lines.
  • both the seat pan 102 and the back bar 104 are pivoted, but by larger angles.
  • the seat pan 102 is lowered in its rear region, that is, when the lever 32, 34 is pivoted clockwise from the position shown by solid lines, the inclination of the seat pan 102 changes by a smaller angle than that of the back bar 104.
  • This chair therefore has the advantage that the angle between the seat shell and the back bar is larger in the reclined position, so that a comfortable position for relaxation can be adopted.
  • FIG. 10 shows a perspective view of a piece of seating furniture according to FIG. 9, the same reference numerals as in FIG. 9 being used for the same parts. Since this figure is self-explanatory, no further description is necessary.
