Definitions

  • the invention relates to a device for adjusting the seat depth of a chair with a seat support.
  • the seat depth adjustment should be structurally simple and, with a padded seat support, ensure that the upholstery rolls up and down without wrinkles when the seat depth is adjusted.
  • the present invention proposes a device for adjusting the seat depth of a chair with a seat support, which is characterized by an adjustment part which can be pulled out on the front edge of the seat support and in which a spindle is rotatably mounted, two nuts being arranged on the spindle are, which move in opposite directions on a rotation of the spindle on the spindle and to which a strut is articulated to the seat support.
  • the nuts move either outwards or inwards.
  • the struts articulated on the nuts either extend in the longitudinal direction of the seat or are angled more strongly with respect to this.
  • the adjustment part is more or less extended from the seat support and thus the seat depth is correspondingly larger or smaller.
  • the articulation points of the struts on the seat support can preferably be arranged in the region of the vertical central plane in the seat direction of the seat support.
  • the adjustment part can be arranged so that it can be pulled out on the seat body by means of two guide tubes which are fixedly connected to the adjustment part and are displaceably mounted on the seat support. This allows a very low-friction change in the position of the adjustment part.
  • the spindle can be rotated by means of at least one handwheel, but preferably two handwheels, so that the adjustment can be carried out with both the left and the right hand.
  • a cushion receiving tube can also be arranged coaxially to the spindle, to which the front edge of the cushion is fastened and which has a guide slot which extends at least over a length section and through which the nuts are guided outwards.
  • the guide slot for example the shape of two counter-rotating threads with a large pitch
  • the upholstery tube is also set in slight rotation by the nuts moving along the guide slot. This rotation of the upholstery tube allows the upholstery to roll up when the seat depth is reduced and to roll back up when the seat depth is increased.
  • the course of the guide slot and the thread pitch of the spindle can be coordinated with one another in such a way that when the seat depth is changed, the upholstery rolls up and rolls off the upholstery receiving tube without creases.
  • the shape and length of the guide slot in the upholstery tube can be individually adapted to a wide variety of seat supports.
  • One possibility is, for example, to design the guide slot in a V-shape, the tip of the V being arranged at least approximately in the middle of the tube. In this way a linear adjustment can be obtained when the spindle is rotated.
  • the upholstery can be attached to the upholstery receiving tube by means of a welt.
  • the adjustment part can have a carrier element and a cover, which together form a receptacle for the cushion receptacle tube and the spindle arranged therein.
  • the tube and the spindle then roll off in this holder.
  • the cushion receiving tube can be supported on the spindle by lateral guide bushings.
  • the single 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 cushion, not shown here.
  • the seat depth adjustment 11 has a support part 12, which is mounted on two guide tubes 13 on the seat support 10 so that it can be pulled out.
  • the carrier part 12 is covered by a cover 14 which, together with the carrier 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 inside the cushion guide tube 15.
  • the spindle 16 can be set in rotation by means of hand wheels 17. It is provided with two opposite thread sections 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 at their other ends on the seat support 10.
  • the articulation points of the struts 19 on the seat support 10 lie close to the vertical central plane 20 of the seat support 10.
  • the support part 12 is moved further out on the guide tubes 13 by rotation of the spindle 16 by means of a handwheel 17, as a result of which the seat depth is extended.
  • the struts 19 then stretch namely.
  • the nuts 18 move apart when the spindle 16 rotates in the opposite direction, the carrier part 12 and with it the cover 14 which is firmly screwed to it are moved further inwards towards the seat carrier 10 on the guide tubes 13.
  • the cushion receiving tube 15 is mounted on the spindle 16 by means of lateral guide bushings 21.
  • the front edge of the cushion is on the cushion receiving tube 15 attached, for example, with 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 region.
  • the articulation points 18.1 of the nuts 18 protrude through this guide slot 22.
  • the shape of the guide slot 22 and a corresponding choice of the pitch of the threaded sections 16.1 of the spindle 16 can ensure that the rotational movement of the spindle 16 is converted into a linear movement of the carrier part 12 and the cover 14. At the same time, it is ensured that the cushion remains wrinkle-free when rolling and rolling onto the cushion receiving tube 15.
