Definitions

  • the invention relates to an adjustment fitting according to the preamble of patent claim 1.
  • the driven eccentric area is formed by two eccentric disks which can be pivoted relative to one another about the axis of rotation under the action of a spring. Both eccentric discs lie with their outer peripheral surfaces directly in two spaced lines on the associated bearing. This construction is therefore also sensitive to wear.
  • the invention is based on the object of designing an adjustment fitting of the type presumed to be known in such a way that it is designed to be rotatably insensitive to wear and rattling-free.
  • Figure 1 an exploded perspective view of an adjustment fitting
  • Figure la the exploded view of Figure 1 in a second viewing direction
  • Figure 2 shows a section along a vertical plane through the backrest-fixed fitting part of the adjustment fitting according to Figure 1 with an eccentric in the non-actuated state.
  • Figure 3 an enlarged section of the eccentric area of the adjustment fitting according to Fig. 2;
  • FIG. 4 the detail according to FIG. 3 without the pane lying at the front or at the top in FIG. 3;
  • 5 shows a representation corresponding to FIG. 1 of a second embodiment;
  • Figure 6 - a representation corresponding to Figure 2 of the second embodiment;
  • Figure 8 - a Fig. 4 corresponding representation of the second embodiment.
  • the adjustment fitting shown is in principle a typical inclination adjustment fitting for a backrest of a motor vehicle seat. It has a fixed fitting part 1, which is connected to a seat part, not shown, and a rotationally adjustable fitting part 2, which is connected to the backrest, also not shown.
  • the fitting part 1 has a toothing la, which is intended for circumferential engagement in a toothing 2a of the movable fitting part 2.
  • the toothing la is an external toothing while the toothing 2a is designed as an internal toothing.
  • Both gears la and 2a are part of a wobble mechanism.
  • the fitting part 2 has a rotary bearing 2b, which is formed by the circular cylindrical inner surface of a passage or collar 2d, the circular cylindrical outer surface of which is designated 2c.

Abstract

L'invention concerne une armature de réglage d'un siège de voiture, notamment une armature de réglage de l'inclinaison du dossier d'un tel siège. Selon l'invention, une partie d'armature (1) affectée à une partie fixe du siège est reliée par l'intermédiaire d'un excentrique (4) à une partie d'armature rotative (2) affectée à une partie mobile du siège. La partie de l'excentrique (4c; 4d; 4e; 4f) logée dans un deuxième palier rotatif (1b) comporte deux pièces coulissantes (4c; 4d) courbées autour de l'axe de rotation (3), présentant respectivement des conicités opposées ainsi que des contours périphériques extérieurs et intérieurs. Un ressort (5) sert à déplacer les pièces coulissantes (4c; 4d) l'une contre l'autre dans le sens périphérique. La partie de l'excentrique est constituée par les pièces coulissantes (4c; 4d) et par deux disques (4e; 4f) pouvant tourner autour de l'axe de rotation (3), supportés l'un contre l'autre par le ressort (5). Lesdits disques présentent des cavités (4h; 4i) séparées l'une de l'autre par l'intermédiaire de zones entretoises radiales (4g), les pièces coulissantes (4c; 4d) étant logées dans lesdites cavités. Lesdites cavités (4h; 4i) présentent des bases (4k; 4l) courbées en fonction des contours périphériques d'appui des pièces coulissantes.
