Definitions

  • the invention relates to seating furniture in accordance with the preamble of patent claim 1.
  • the adjusting 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 a control 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 inclination adjustment of the seat part and backrest is provided in a ratio of approximately 1: 2 (exemplary embodiment of FIGS. 6, 6a) .
  • the invention has for its object to develop a seating of the type mentioned in such a way that his, the armchair shell contour in stable support and flexible elastic zones Changing shell elements when changing the seating position of the armchair user automatically and continuously and much better to adapt to the movement sequences taking place, i.e. the active body motor and supporting the body of the armchair user in the pelvic lumbar area throughout.
  • the weight-based, adjustable spring base of the swing arm of the armchair which is used to hold 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 schematic representation according to FIG. 1 illustrates the possible transfer of the seating furniture from a position which is optimal for the posture of the working user (working position according to solid lines) to an extreme rear resting position (dashed lines), but also the basic structure of the seating furniture :
  • the pedestal 10 comprises a height-adjustable support spindle 10a.
  • a seat part carrier 11, which is shown in FIGS. 6-8, is rotatably received by the latter.
  • the seat part carrier is plugged onto the upper end of the support spindle 10 in the region of its receiving part 11a provided with a receiving bore.
  • the seat part carrier 11 extends widening forward, where it ends in a linear and transverse to the plane of symmetry bb section 11b (Fig.4).
  • Bearing eyes 11c for the coaxial axle bolts 12 of the rocker arm 14 and further bearing eyes 11c ⁇ for the coaxial axle bolts 32 of the synchronizing lever 25 are molded onto this bearing section 11b, as shown in particular in FIGS. 6-8 in connection with Fig. 4 can be seen.
  • the vertical parallel projection of the seat part carrier corresponds approximately to an isosceles triangle, as can be seen in particular in FIG. 7.
  • the front seat part S is formed from the rocker arm 14, the associated seat shell 18a and the upholstery 18b and via the rocker arm 14 with the aid of the axle bolts 12 in one the front edge of the seat part S adjacent region articulated on the seat part carrier 11.
  • a pelvic lumbar support B ending in the lumbar region of the chair user is connected via a horizontal pivot axis 17 ⁇ .
  • the body motor pivoting of the seat part S and pelvic lumbar support part B is synchronized with the aid of synchronizing levers 25 such that pivoting the seat part S forces the pelvic lumbar support to be pivoted by a pivoting angle which is 2.5 times greater than the pivoting angle of the seat part S.
  • the backrest R is connected directly to the upper edge of the pelvic lumbar support B and is connected to it via a pivot axis 36. A swiveling out of the backrest R caused by body movement takes place counter to the action of a spring force.
  • This is preferably formed by leg springs 42 (in FIG. 2) which are received by the axle bolts forming the pivot axis 36 and whose legs rest on the lumbar lumbar support B on the one hand and on the backrest R on the other hand.
  • the input section b of the lumbar lumbar support B adjoining the seat part S extends approximately perpendicularly 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 lever 25 engages over the coaxial Axle pin 32 on the seat part support 11.
  • the axle bolts 32 are located approximately in a vertical plane aa (FIG. 3) giving the rocker arm 14 through the pivot axis 32 ⁇ (FIG. 1).
  • the synchronizing lever 25 is articulated on the pelvic lumbar support part B via a transverse axis 30.
  • the transverse axis 30 is offset from the pivot axis 17 'formed by the axle bolts 17' of the pelvic lumbar support B in such a way back and down that there is a pivoting ratio between the rocker 14 and the pelvic lumbar support B of about 1/5.
  • 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 a transverse axis 30 and a transverse bolt 31 parallel to this transverse axis 30 and extends forwardly under the seat part S.
  • the frictional plate pack 24 has its arcuate longitudinal slot penetrated by the clamping bolt 22.
  • 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 slot limits the potential pivot angle of the rocker 14 and thus the seat part S.
  • a coil spring 13d for springing the rocker 14 is arranged symmetrically to the plane of symmetry aa (FIG. 4) between the support spindle 10a and the front edge of the seat part S and is thereby 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 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 located, 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 aa are provided for the suspension of the rocker 14. Their arrangement in the space between the bore 10a ⁇ and 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.
  • the axle bolts 17 (FIGS. 2, 3) forming the pivot axis 17 ⁇ (FIG. 1) pass through bearing eyes 14b of the rocker arm 14, which is mounted on the axle bolts 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 pivot axis 36 of the backrest R is about 14 cm above the 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 support surface of the input section of the pelvic lumbar support B and the support surface of the seat part S lie 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 considerable shift of the body's center of gravity backwards, so that there is a risk of the seating furniture tipping over backwards. This danger can be countered, for example, by a corresponding restriction of the backrest R being able to be swung out backwards.
  • a device can be provided to reliably avoid the risk of the seating unit tipping over, which causes the center of gravity to be shifted forward when the seated person leans backwards with the backrest swung out to the maximum.
  • 15 and 16 shows how this device is constructed and works:
  • the axle bolts 12 of the rocker arm 14 are horizontally displaceably mounted in horizontal elongated holes 50 of the stationary seat part carrier 11.
  • the maximum displacement X corresponds to the length of the elongated holes 50.
  • the shell contour formed from the front seat part S, pelvic lumbar support B and backrest R is the body-supporting shell contour during the transition of the seating furniture from the working position ( Fig. 15) in the rest position (Fig. 16) by the distance X to the rear.
  • the displacement is effected with the aid of a lever system H which is articulated to the rocker 14 for the seat part S, the support plate 15 for the lumbar lumbar support B and the stationary seat part carrier 11.
  • This comprises two levers 51 which are articulated on one end to the stationary seat part support 11 by means of axle bolts 52 and at the other end on the rocker 14 by means of axle bolts 53.
  • lever 51 With upper extension ends 51 ⁇ of the lever 51 are 56 two axle bolts further levers 54 are articulated, which are articulated on the back by means of axle bolts 55 for support plate 15 for the pelvic lumbar support B.
  • the horizontal displacement of the body-supporting shell contour formed by the distance X backwards from the front seat part S with rocker 14, the pelvic lumbar support B with the support plate 15 and the backrest R is caused by the pivoting of the pelvic lumbar support B backwards.
  • the levers 54 are essentially forward to a position according to FIG. 16 due to a forced guidance of the axle bolts 55 about the axis 17 ⁇ in a circular arc K ⁇ from a position according to FIG. 15 postponed.
  • the levers 51 are pivoted from their position according to FIG. 15 into the position according to FIG. 16 about the stationary axle bolts 52. Since these levers 51 are articulated in their upper half via the axle bolts 53 to the rocker 14, the movement unit referred to above as the shell contour is shifted forward by the distance X by its pivoting.
  • the risk of the seating furniture tipping over on the back is reliably avoided, even if the seated person leans backwards in the rest position with the backrest swung out to the maximum.
