Definitions

  • the invention relates to seating furniture according to the preamble of patent claim 1.
  • the adjustment device forces a simultaneous synchronous adjustment of both the front seat part and the backrest, as well as the pelvic lumbar support, the output section of which, when the seating furniture is transferred from the working position to the rest position extends at least over the entire lumbar region of the spine of the chair user. If the known seating furniture is in the working position, the seating surface runs approximately horizontally.
  • the adjusting device comprises an adjusting lever which is curved over approximately 90 ° and which is articulated on the seat part carrier and articulates on the backrest.
  • the adjusting lever can be swiveled using a pneumatic cylinder.
  • the pelvic lumbar support is supported on the adjusting lever by an approximately vertically arranged spring.
  • the rocker arm can be fixed in a set position by means of a friction-locking lamella package through which a clamping bolt passes, and a forced and synchronous tilt adjustment of the seat part and backrest is provided in a ratio of approximately 1: 2 (WO 86/00508, embodiment of the Figures 6, 6a).
  • the invention has for its object to develop a piece of seating of the type mentioned in such a way that its shell elements, which divide the armchair shell contour into stable support and flexible elastic zones, change automatically and continuously when the seating position of the armchair user changes, and much better the movements taking place , i.e. adapt to the active body motor and support the body of the chair user in the pelvic lumbar area throughout.
  • the pelvic lumbar support B has the consequence that the seat surface has a kink to a certain extent when the seating is in the working position by the supporting surface of the input section b of the pelvic lumbar part (B) with the adjacent supporting surface of the front seat part S obtuse angle (ß in Fig. 2) includes.
  • the weight-based, adjustable spring base of the swing arm of the chair that holds the seat shell, in conjunction with a harmoniously graduated upholstery of the various support areas of its seat shell, ensures pleasant contact with the seat and back thanks to the large area of the body load.
  • the synchronous adjustment of the seat, rear transition zone and backrest profile results in a fatigue-free balance of the upper body with optimal mobility and prevents the pelvis from tilting excessively in every sitting position.
  • the input section b of the pelvic lumbar support B adjoining the seat part S runs approximately perpendicular to its output section b 'adjoining the backrest R.
  • This output section b ' is approximately half as long as the input section.
  • the inlet section and outlet section merge into one another via an arcuate section k (FIG. 2).
  • the synchronizing levers 25 engage on the seat part carrier 11 via the coaxial axle bolts 32.
  • the axle bolts 32 are located approximately in a vertical plane aa passing through the pivot axis of the rocker 14 (FIG. 3).
  • the synchronizing lever 25 is articulated via a transverse axis 30 to a support plate 15 arranged on the lumbar-lumbar support part B.
  • the transverse axis 30 is offset relative to the second pivot axis 17 'of the rocker arm 14 formed by the axle bolts 17 in such a way that a pivoting ratio between the rocker arm 14 and the pelvic lumbar support B is approximately 1 / s.
  • two friction-locking plate packs 24, 33 are provided, which lie symmetrically to the plane of symmetry bb (FIG. 4) and are penetrated by a clamping bolt 22 which can be controlled manually by means of an eccentric.
  • the pelvic lumbar support B arresting frictional lamella pack 24 is rigidly connected to the pelvic lumbar support B via the transverse axis 30 and via a transverse bolt 31 parallel to this transverse axis 30 and extends forwardly under the seat part S.
  • the friction-locking plate pack 24 has a circular arc-shaped, penetrated by the clamping bolt 22 longitudinal slot.
  • the friction plate pack 33 for locking the rocker 14 is pivotally mounted on a stationary bearing axis 23 of the seat part carrier 11, extends approximately in the vertical direction. The length of its elongated hole limits the potential pivot angle of the rocker 14 and thus the seat part S.
  • a coil spring 13d for supporting the rocker 14 is arranged symmetrically to the plane of symmetry aa (FIG. 2) between the support spindle 10a and the front edge of the seat part S and is caught between a support bearing of the rocker 14 and a lower bearing plate 13e.
  • the coil spring 13d is provided with a device 13 for changing its pretension.
  • This device 13 comprises a screw bolt 13b which is provided with a handwheel 13a and which engages with the internal thread of a screw nut 13c fixed in the seat part carrier 11, as can be seen in particular from FIG. 2.
  • the bearing plate 13e sits on the screw bolt 13b and can thus transmit the axial movement component of the rotating screw bolt 13b to the coil spring 13d.
  • Two further helical springs arranged on both sides of the plane of symmetry bb are provided for the suspension of the rocker 14. Their arrangement in the space between the bore 10a 'and the support spindle 10a and the helical spring 13d results from FIG. 7, where the abutments 11f are indicated for these further helical springs. The position of the helical spring 13d also results from FIG.
  • 11 i denotes a recess corresponding to the screw nut 13c, in which this screw nut 13c is received in a form-fitting manner.
  • the axle bolts 17 (FIGS. 2, 3) forming the second pivot axis 17 ′ (FIG. 1) pass through bearing eyes 14b of the rocker 14, which is mounted on the first pivot axis 12 via the bearing eyes 14a.
  • the rocker 14, as can be seen in particular from FIG. 10, has two legs 14c which extend between the bearing eyes 14a and 14b and are connected to one another via a bridge 14f. With 14d formations are designated, which form a bearing for the clamping device for locking the inclination of the seat part S and pelvic lumbar support B.
  • the third pivot axis 36 of the backrest R is about 14 cm above the second pivot axis 17 'of the pelvic lumbar support B when the armchair is in the working position. When the armchair is extremely at rest, the supporting surface of the input section of the pelvic lumbar support B and the supporting surface of the seat part S are in a common, slightly backward inclined plane cc (Fig. 3).
  • the seating furniture is moved from a working position (Fig. 2, 15) to a rest position (Fig. 3, 16 ) transferred.
  • the rest position the seated person can stretch or bend his back back against the force of the spring 42. This results in a significant shift of the body's center of gravity backwards, so that there is a risk of the seating furniture tipping over backwards. This risk can be countered, for example, by a corresponding restriction of the backrest R being able to be swung out backwards.
