  • the mobility This spring means 4 is the intervention of the Tongue 12 and its grid pin 14 on the grid element thirteenth blocked, because with it a stable connection between seat plate 1 and seat support 3 is created.
  • the tongue 12 also includes an activator rod 19 which supports the piston 16 connects with a spring element 20.
  • Am as a torsion spring trained spring element 20 engages an operating rod 21, which preferably at its end a control knob 22 has.
  • the control button comprises a cam 23, which is acted upon by a spring 24.
  • the Blocking mechanism be carried out completely different: z. can the tongue 12 slidably on the seat plate carrier 3 and the grid element be arranged on the seat plate 1. Also can the spring element 20 e.g. be formed as a leaf spring. Also the shape and arrangement of operating rod 21 and Control button 22 and the suspension 24 is at will a specialist, provided at least the functions described are guaranteed.
  • the torsion spring builds a tension in the opposite direction (see arrow in Fig. 2e) and pulls on the grid pin 14. This can but do not leave the grid element 13, because - because of the tension, by the spring element.4 or by the weight of the seated Person generated - the frictional forces between the teeth of the raster element 13 and the grid pin 14 to are large (Fig. 2e). Because of the suspension 24, which against presses the pre-selection, the prefix can not in his swing back to previous position.
  • FIG. 3 shows a seat and backrest arrangement according to the invention, according to a second embodiment.
  • This embodiment differs from the first in that a third joint 26 in the area of the anterior, knee-sided Edge 2 of the seat plate 1 is arranged and this seat plate connects to the seat plate carrier 3.
  • the already described Synchronous mechanism by means of which with a single or with several spring means 4 and the two 7,8 joints the seat plate 1 and the backrest support. 6 or the backrest 11 are cushioned is, by the third joint 26 not impaired.
  • the third joint 26 allows the third joint 26 the additional use of a Adjusting means 27, with which the spring force of the spring means 4 can be changed. This will be further down on hand Figure 4 explained in more detail.
  • the inventive seat and backrest arrangement shown here an additional seat depth adjustment.
  • the first joint 7 between seat plate 1 and backrest support 6 is also carried out slidably, the Backrest support 6 also moved relative to the seat surface 28 become.
  • a Body 29 includes, which in or on the backrest support 6 is arranged displaceably.
  • the backrest support 6 has for this purpose a guide member 30, the here is formed as a recess and in which the body 29th is slidably disposed.
  • the Backrest 11 adjusted to the seat 28 and held has the body 29 grid grooves 31, in which engages a lever 32.
  • the adjusting lever 32 is is arranged on a hinge on the backrest support 6 and is preferably permanently against the body 29 by a spring and thus pressed into one of the grid grooves 31. This is the seat depth adjustment lockable formed.
