Definitions

  • the invention relates to a seat, such as a motor vehicle seat with a base frame, a seat cushion frame supported on the base frame with a seat cushion arranged thereon and a backrest connected to the base frame, wherein the seat cushion frame is articulated to the base frame. Furthermore, the invention relates to a joint cassette, preferably for installation in a motor vehicle seat for converting the motor vehicle seat into one with an exit and boarding aid.
  • Motor vehicle seats have a base, which is typically held in a pair of rails and adjustable in the longitudinal direction of the vehicle.
  • a backrest is articulated to the underframe and a seat cushion frame with a seat cushion arranged thereon is fastened.
  • the seat cushion in a motor vehicle seat engages under the lower end of the backrest.
  • motor vehicle seats which have exit or entry aids. From US 5 636 884 A, such a seat is known.
  • the motor vehicle seat described in this document is arranged on a carrier unit.
  • the carrier unit itself is displaceable in transverse to the longitudinal extent of the vehicle guide rails to bring the seat closer to the vehicle door opening to facilitate entry and exit.
  • the carrier unit comprises a hinge, by means of which the seat is pivotable about a vertical pivot axis, so that the front side of the seat for facilitated getting in and out points in the direction of the motor vehicle door.
  • the carrier unit has a lifting fitting, with which the seat can be raised and lowered slightly.
  • the arrangement described in this document comprises a motor vehicle seat and a carrier unit and can be used only in vehicles with a larger interior, in particular in vehicles with a sliding door, since then this motor vehicle seat adjacent to the sliding door door can be arranged.
  • a stand-up aid has become known.
  • This stand-up is part of a motor vehicle seat.
  • a stand-up aid is incorporated in the seat frame or seat cushion.
  • the stand-up as part of the seat cushion is tiltable about an axis located in its front end horizontal extension, with the result that the backrest facing completion of this seat cushion segment can be raised.
  • the vehicle seat as a whole can be pivoted about a vertical axis by a few degrees so that the front of the seat can be pivoted in the direction of the vehicle door. While the vehicle seat described in this document with its stand-up aid and its pivotability can basically be used in any motor vehicle, the help provided by this seat for getting in and out is in many cases not sufficient.

Abstract

La présente invention concerne un siège (1), conçu par exemple comme siège de véhicule, comprenant un cadre inférieur (2), une structure de rembourrage de siège (8) appuyée sur le cadre inférieur (2) et sur laquelle est disposé un rembourrage de siège (4), et un dossier (3) relié au cadre inférieur (2). La structure de rembourrage de siège (8) est reliée de façon articulée au cadre inférieur (2). Grâce à la liaison articulée, la structure de rembourrage de siège (8) avec son rembourrage (4) peut être déplacée depuis une position de base, correspondant à peu près à la position de conduite de la structure de rembourrage de siège (8), dans une première section de déplacement en direction du dossier (3), pour être utilisée comme aide à la descente et à la montée, avant de pouvoir être ensuite pivotée dans une autre section de déplacement par rapport au cadre inférieur (2). Un châssis articulé (27), à encastrer dans un siège conçu par exemple comme siège de véhicule entre son cadre inférieur et sa structure de rembourrage de siège, destiné à équiper le siège de véhicule doté d'un tel système d'aide à la descente et à la montée, comprend une partie inférieure (28) pouvant être reliée au cadre inférieur du siège de véhicule et un support de structure de rembourrage de siège (30) pouvant être relié à la structure de rembourrage de siège. Le support de structure de rembourrage de siège (30) est relié de façon articulée à la partie inférieure (28) et peut être déplacé depuis la position de conduite du support de structure de rembourrage de siège (30) par rapport à la partie inférieure (28) dans une première section de déplacement en direction de la position finale précédente du châssis articulé (27) par rapport à la partie inférieure (28), avant que le support de structure de rembourrage de siège (30) ne puisse être ensuite pivoté dans une autre section de déplacement par rapport à la partie inférieure (28) transversalement à l'extension longitudinale du châssis articulé (27) par rapport à la partie inférieure (28).
