Definitions

  • the seat plate 2 is pivotable together with the backrest 3 in the longitudinal direction, that is, forwards and backwards. This is illustrated by the double arrow 5 on the seat plate 2.
  • This pivotability of the seat plate 2 forward and backward is synchronized with the pivoting of the backrest 3 in these directions. In the illustrated embodiment, this is done via a slot guide.
  • two elongated holes 21 are secured by means of the elongated hole carrier 30 on the underside of the seat plate 2.
  • a bolt 22 is fixed, which is guided in the slots 21.
  • these distances X and Y are measured in a state in which the chair 1 is in an unloaded operating state, in which neither the seat plate 2 nor the backrest 3 by a seated on the chair 1 person or otherwise deflected or loaded.
  • Fig. 6 a third embodiment of the invention is illustrated. However, here in analogy to Fig. 2 only the area of the seat plate 2 and its closer environment shown. The rest of the design of the chair 1 can be realized as in the first embodiment.
  • two pivot joints 6 and 7 are present. However, these are not designed as axle joints but as axleless bending joints.
  • the hinge parts 25 and 26 are each designed as a rigid body. Between them is in each case an elastic damping body 12, which fulfills a dual function here. On the one hand, he allows the side swinging back and forth of the seat plate 2 in directions of the double arrow 8 not shown here. On the other hand, it also dampens this pivoting movement at the same time.
  • the damping body 12 may be e.g. be attached by bonding between the joint parts 25 and 26.
  • a fourth embodiment of the invention is shown, which is based essentially on the variant according to Fig. 6 based. However, here the area of the pivot joint 6 is even further simplified.
  • the hinge part 25 of the pivot joint 6 rigidly arranged on the support arm 18 and integrated in this.
  • the damping body 12 has in this embodiment according to Fig. 6a then a total of three tasks. It allows the lateral pivoting in the transverse directions 8, the pivoting back and forth in the direction of the double arrows 5 and additionally ensures the damping of this pivoting movement.
  • Fig. 6a are also once again the horizontal distances X and Y located, which are also in the aforementioned ratio ranges, in order to realize a weight automatic also in this variant.
  • Fig. 6a replaced the pivot joint 6, as I said, the joint 33, so that here the horizontal distance X from the center of the executed as a bending joint pivot joint 6 must be measured.
  • the first leaning point 29 of the backrest 3 is not shown. He will, however, as in Fig. 2 shown, determined.
  • Fig. 7 a fifth alternative according to the invention is shown. Only one alternative of region C is shown Fig. 6 and thus the third embodiment.
  • the rear pivot 6 is not designed as achslosen bending joint but as a ball joint. Shown is the ball joint in a sectional view.
  • the spherical head receptacle is in this embodiment in fixed to the base 4 and the column head 15 connected joint part 26.
  • the ball joint allows both the lateral pivotal movement in the direction of the double arrows 8 and the pivotal movement of the seat plate 2 and the backrest 3 forward and back according to of the double arrow 5. This can be dispensed with the joints 23 and 33 in this embodiment.
  • Fig. 7 is of course only one embodiment of the use of a ball joint. Ball head and ball head receptacle can of course be arranged reversed. In addition, the ball joint can also accept all other known embodiments of ball joints, as long as they are used in a corresponding manner.
  • the remaining components of the chair 1 of this fourth embodiment according to Fig. 7 can be realized, for example, as in one of the other embodiments described here. This is especially true for the connection between the front half 9 of the seat plate 2 and the base 4 and for the automatic weight.
  • Fig. 8 now shows a sixth embodiment of the invention. Again, only on the specifics or differences of this embodiment the previously described embodiments received.
  • the main difference to the previously described embodiments is the design of the here bent C-shaped bending spring 19. It connects the front half 9 of the seat plate 2 with the column head 15 and thus with the base 4.
  • the spiral spring 19 can pivot forward and backward of the backrest 3 and seat plate 2 and also provides the corresponding counter-forces or restoring forces with respect to this pivoting motion available.
  • this bending spring 19 can be regarded as a front pivot joint 7, depending on the embodiment, if it allows a corresponding lateral swinging back and forth along the double arrows 8 of the seat plate 2.
