Definitions

  • the invention relates to a device for adjusting the seat depth of a chair with a seat support having the features of the preamble of claim 1.
  • a seat depth adjustment device for a motor vehicle seat which has seat-fixed guide areas which extend in the seat longitudinal direction and parallel to one another.
  • a Weg brieflyenver scholaril is guided longitudinally displaceable and adjustable by means of a threaded spindle and spindle nut having gear in the seat longitudinal direction.
  • the threaded spindle is mounted transversely to the seat longitudinal direction on the vehicle seat.
  • An articulated lever is articulated on the one hand to the spindle nut and on the other hand with its other end to the Wegtiefenverexcellentil, wherein the projection of the articulated lever on the Wegtiefenverexcellentil in each angular position with the threaded spindle forms an angle.
  • the seat depth adjustment should be structurally simple and ensure that the upholstery folds up and down with an adjustment of the seat depth in the case of a padded seat support.
  • the present invention proposes a device for adjusting the seat depth of a chair with the features of claim 1.
  • the nuts move either outwards or inwards.
  • the struts articulated on the nuts either extend in the longitudinal direction of the seat or become more angled relative to the latter.
  • the adjustment is more or less extended from the seat support and thus the seat depth is correspondingly larger or smaller.
  • the pivot points of the struts on the seat support may preferably be arranged in the region of the vertical center plane in the seat direction of the seat support.
  • the spindle may have two opposing threaded portions for making the counter-rotating movement of the nut, which may, for example, meet in the center of the spindle.
  • the adjustment can be arranged by two guide tubes, which are fixedly connected to the adjustment and slidably mounted on the seat support, extendable on the seat body. This allows a very low-friction change in the position of the adjustment.
  • the rotation of the spindle can be done by means of at least one hand wheel, but preferably two hand wheels, so that the adjustment can be made with both the left and the right hand.
  • a cushion receiving tube Coaxially to the spindle, a cushion receiving tube is arranged, on which the pad leading edge of a pad is attached and which has a at least over a longitudinal portion extending guide slot through which the nuts are passed through to the outside.
  • the pad receiving tube is set in a slight rotation during a rotation of the spindle by the migration of the nuts along the guide slot.
  • the course of the guide slot and the thread pitch of the spindle can be adjusted to one another in such a way that, when the seat depth changes, the pad rolls up onto the upholstery receiving tube without wrinkles and unwinds from it.
  • the guide slot of the upholstery tube can be tailored in shape and length individually to a variety of seat support.
  • One possibility, for example, is to form the guide slot V-shaped, wherein the tip of the V is arranged at least approximately in the center of the tube. In this way, a linear displacement can be obtained when the spindle is rotated.
  • the pad can be attached by means of a welt on the upholstery tube.
  • the adjustment part may have a carrier element and a lid, which together form a receptacle for the upholstery receiving tube and the spindle arranged therein.
  • the tube and the spindle then roll off in this receptacle.
  • the upholstery receiving tube may be supported by lateral guide bushes on the spindle.
  • the sole FIGURE shows an exploded view of a seat support 10 with a seat depth adjustment device 11.
  • the seat depth adjustment device 11 is arranged on the front edge 10.1 of the seat support 10.
  • the seat support 10 is provided on the top with a pad, not shown here.
  • the seat depth adjustment 11 has a support part 12 which is mounted extendable on two guide tubes 13 on the seat support 10. At the top, the support part 12 is covered by a cover 14, which together with the support part 12 in the front region forms a receptacle closed by more than 180 ° for a cushion guide tube 15 and a spindle 16 arranged within the cushion guide tube 15.
  • the spindle 16 can be rotated by means of hand wheels 17 in rotation. It is provided with two opposing threaded portions 16.1 and 16.2, on each of which a nut 18 is arranged.
  • the nuts 18 have articulation points 18.1 for two struts 19, which are articulated with their other end on the seat support 10.
  • the pivot points of the struts 19 on the seat support 10 lie close to the vertical center plane 20 of the seat support 10.
  • the support member 12 is moved by a movement of the nuts 18 by rotation of the spindle 16 by means of a handwheel 17 further on the guide tubes 13 to the outside, thereby the seat depth is extended.
  • the struts 19 then stretch.
  • they are in an apart moving the nuts 18 in rotation of the spindle 16 in the opposite direction stronger angled, causing the support member 12 and with him the screwed tightly with him cover 14 continue on the guide tubes 13 inwardly towards seat support 10.
  • the upholstery receiving tube 15 is mounted on the spindle 16 by means of lateral guide bushes 21. At the upholstery receiving tube 15, the leading edge of the pad, not shown here attached for example by means of a welt.
  • the cushion receiving tube 15 also has a guide slot 22 which extends over part of the length of the guide tube 15 and has a V-shaped portion. Through this guide slot 22 protrude the articulation points 18.1 of the nuts 18 therethrough.
