Definitions

  • the invention relates to a device for adjusting the neck support of a chair, in particular a chair with tilt-adjustable backrest.
  • a device for a tilt-adjustable chair wherein the neck support at the upper end of the backrest has an arcuate guide to so the tension and the relaxation of the chair cover in the area of the neck support too to decrease.
  • this arcuate guide engages a adjustable in length pull rod a, which extends along the backrest and with the lower end with a device articulated, by which the seat is pushed back and forth when the backrest is adjusted in the inclination.
  • the invention has for its object to design a chair with neck support so that with a simple structure, the neck support can be adjusted so that they are the respective Sitting or lying position is best adapted.
  • Fig. 1 denotes the seat of an armchair, which are laterally provided with armrests can and is provided in the usual way with a fabric cover.
  • a backrest 3 hinged about a horizontal pivot axis 10, so that they by a not shown Device preferably be continuously adjusted in inclination relative to the seat can.
  • a neck support 8 is attached, depending on from the inclination position of the backrest 3 a different inclination relative to this occupies, as the movement in Fig. 1 between a tilt position of 5 ° the backrest 3 relative to the seat 7 and a tilt position of 70 °.
  • Fig. 2 shows in detail the fitting or the device according to Fig. 1.
  • the neck support. 8 is on an arm 1 'of a two-armed lever 1 in a predetermined position relative to Backrest 3 attached when the backrest 3 in the reproduced in Fig. 2 sitting position which corresponds approximately to the first position with 5 ° tilt angle in Fig. 1.
  • the two-armed lever 1 is articulated at the upper end of the backrest 3 at 1b.
  • the one in one Angle of about 135 ° of the mounting arm 1 'projecting second arm 1 " the may be shorter than the serving for the attachment of the neck support 8 arm 1 ', is hinged at the end with a handlebar 4 at 1a, which is substantially along the backrest 3 extends.
  • a two-armed link lever 2 is articulated at 2b, its arms 2 'and 2 "protrude at an angle of about 110 ° from the pivot point 2b, wherein in the illustrated embodiment, the upper link arm 2 'slightly longer is formed as the lower link arm 2 ".
  • the end of the upper link arm 2 ' is at 2a hingedly connected to the handlebar 4, while the end of the lower arm 2 "at 2c is pivotally connected to a guide rod 5, which is connected to the opposite end is hinged at 6 at the seat 7.
  • the articulation points 1b, 2b and 6 are stationary, while the Change in position 1 a, 2 a and 2 c in position, as shown in FIG. 3 shows schematically.
  • the guide rod 5 acts as a push rod relative to the handlebar lever 2 in the way that the lower link arm 2 "pivots counterclockwise about the pivot point 2 b is because the fixed pivot point 6 on the seat 7 in Fig. 2 right of the horizontal Pivot axis 10 between the seat and backrest 3 is positioned.
  • the thrust effect up the handlebar lever 2 is pivoted counterclockwise and thereby the Handlebar 4 is shifted upward, so that the neck support 8 also in the counterclockwise direction is adjusted, as shown by an arrow 11 in Fig. 1.
  • the length dimensions of the individual components of the device are adjusted so that in the maximum inclination position of the backrest 3 of about 70 °, the neck support 8 approximately in a level with which the backrest 3 is located so that the user has a comfortable reclining position can occupy, as shown by the lowest position in Fig. 1.
  • Fig. 3 shows the pivoting range of the handlebar lever 2 about the fixed pivot point 2b of about 90 ° and the pivoting range of the two-armed lever 1 to the fixed pivot point 1b, wherein this pivoting range is slightly smaller than 90 °.
  • the different lengths the guide rod 5 in Fig. 3 show the different effective lengths relative to horizontal pivot axis 10.
  • the neck rest adjustment can be both automatic with the adjustment of the backrest 3, as described above, or motor in that the pivot point 6 of Guide rod 5 is adjusted by a servomotor along the backrest that the Neck rest is changed relative to the backrest in the position without the backrest 3 is even adjusted in their inclination.
  • radially projecting lever can be arranged at the location of the articulation point 6 in Fig. 2nd wherein the pivot point 6 at a radial distance from the pivot axis 10 at one with this connected.
  • the articulation point 6 can also be located in a control groove be guided about the pivot axis 10 which is fixedly connected to the seat 7.
  • Fig. 4 shows a modified embodiment of the fitting, wherein at the upper end of the Backrest 3 a the two-armed lever 1 of FIG. 2 corresponding angled lever 11 is fixed, hinged to the protruding leg 11 ', a fitting plate 12 at 11 b is.
  • the fitting plate 12 is fixed to the neck support 8 and at 12a at a distance from the articulation point 11b hingedly connected to the handlebar stem 4.
  • This is the Anlenkstelle 1b of the upper two-armed lever 1 in the embodiment of FIGS. 1 to 3 in the embodiment of FIG. 4 displaced upward to the neck support on this To steer lever 11.
  • a change of the function does not result because of the Distance of the articulation points 11b and 12a the distance of the articulation points 1a and 1b in Fig.
  • Essential components of the fitting are the two-armed lever 2 and the hinged thereto Guide rod 5 and handlebar 4.
  • Both the articulation of the lower end of the Guide rod can be varied, for example, stationary at 6, this position of the Anlenkstelle 6 can be varied, or it can instead of a fixed linkage also a motor actuation of the guide rod 5 are provided.
  • the linkage the upper end of the handlebar 4 are varied, as the embodiments of FIGS. 1 to 3 and show 4 to 6.
  • the lower pivot point 6 of the guide rod 5 is in this embodiment to a fitting element 14 attached, which is fixedly connected to the frame 7 a of the seat 7.
  • Fig. 5 shows the fitting according to Fig. 4 on a chair with upright position of the backrest 3, while Fig. 6 reproduces the fitting without armchair. At 15 holes are in the Fitting elements 11, 12, 13 and 14 reproduced, inserted into the mounting screws become.
  • the hinge mechanism described can also with a pivotable armrest of a Seating furniture used in which the armrest similar to a backrest in the tilt adjustable and the armrest similar to the neck support adjustable relative to the armrest is.
  • a comfortable lying position can be taken when folding away the armrest become.
  • the armrest another adjustment relative to the armrest perform as described in connection with a neck support.
