Definitions

  • the invention relates to a spring support for a motor vehicle door arrester, in which a rigid door holding rod, which is pivotally articulated on a door arrangement part, door or door pillar, penetrates a holder housing which is rigidly fastened to the other door arrangement part, by means of a support arm arranged in the holder housing on the free load arm and on this via a support arm supported torsion bar spring is freely rotatably arranged loading roller, wherein the torsion bar spring is received in an elongated hole recess of the folded from a sheet material holder housing.
  • the load spring designed as a torsion spring for applying a braking or holding force of the door lock has an S- or C-shaped curvature and is, for example, according to FR-A-2 395 164 over its shaft part and also held or supported via its support arm within an elongated hole recess of a holder housing folded from a sheet material blank, such that its free load arm is deflected by the holder housing when the latching recesses in the door holding rod pass through.
  • the invention is therefore based on the object of using a door arrester which can also be used independently of the door hinges and is equipped with a torsion spring door arrester of the type mentioned at the beginning, which folds out of a sheet metal material blank, in such a way that it operates without noise over its entire service life even with the least possible production outlay.
  • the torsion bar spring is supported with respect to its shaft part within the holder housing via a bearing shell made of self-supporting and maintenance-free bearing material, the bearing shell being held in its position within the holder housing in addition to mechanically acting holding means by a preselected preload between the shaft part and the support arm is.
  • the bearing shell bridges the space between the two to support the shaft part of the Torsion bar spring forming side walls of the holder housing and is additionally protected against wandering in the axial direction by radially positioned ears resting on the outer surfaces of the side walls of the holder housing.
  • This arrangement and design of the bearing shell results in a permanent, maintenance-free and friction-free support of the shaft part of the torsion spring that extends over the entire service life of the door arrester, which in turn guarantees a lasting freedom from noise.
  • the bearing shell is held essentially by the pretension between the shaft part and the support arm of the torsion bar within the recess of the side walls of the holder housing, the implementation of this mounting of the shaft part of the torsion bar spring does not require any special additional manufacturing outlay for the door arrester.
  • An additional securing of the position of the bearing shell can be achieved without further manufacturing effort for the door arrester in that the bearing shell is at the same time also clawed in the outer surfaces of the side walls of the holder housing via the radially flared ears, which is made possible in the simplest way that the ears have a cut directed at an acute angle to the longitudinal axis of the bearing shell.
  • the bearing shell has at least one radially outward projection by means of which it is secured within the holder housing on its transverse wall to prevent it from wandering in both the circumferential and longitudinal directions.
  • the radially outward projection of the bearing shell is arranged centrally by at least one of the bearing shell with respect to its longitudinal extent and with respect to its cross-sectional profile Wart is formed.
  • the bearing shell is supported against migration on a transverse wall or on the two side walls of the holder housing via a plurality of radial projections or warts directed radially to its cross-sectional profile.
  • the holder housing 1 is folded from a sheet material blank in a substantially U-shape and with the foot or.
  • the holder housing 1 formed from a sheet material blank has mutually parallel side walls 8 and a partial transverse wall 9 and is provided with slot walls 10 with respect to its side walls 8, which are penetrated by a torsion bar spring 11.
  • the torsion bar spring 11 is bent essentially S-shaped in the exemplary embodiment shown and rests with its shaft part 12 at one end and with its support arm 13 at the other end of the elongated hole recess 10.
  • the torsion bar spring 11 On its free loading arm 14, the torsion bar spring 11 carries a loading roller 15 which interacts with the back 5 of the door holding rod and which presses the door holding rod against an abutment roller 17 rotatably mounted in the holder housing 1 about a fixed axis 16.
  • the shaft part 12 of the torsion bar spring 11 is interposed supported in cross-section U-shaped bearing shell 18.
  • the bearing shell 18 is held in its position at least partially by the prestress resulting from the predetermined angular position of the shaft part 12 and support arm 13 of the torsion bar spring 11 and consists of a supporting metal, in particular steel backing provided with a Teflon coating, and is at both ends with a radial offset to its profile cross section Provide ears 19 which rest on the outer surfaces of the two side walls 8 of the holder housing 1 and thus additionally secure the bearing shell 18 against wandering in the axial direction.
  • the radially turned ears 19 are intended to claw in the outer surfaces of the side walls 8 of the holder housing 1 in such a way that additional securing of the bearing shell 18 against axial wandering as well as against rotation about the axis of the shaft part 12 of the torsion bar spring 11 is provided .
  • the bearing shell 18 in addition to the ears 19 or only by radially directed to their profile axis or projections, in particular wart-shaped projections 20 against both rotation and against walking in the longitudinal direction the transverse wall 9 of the holder housing is fixed.
  • the wart-shaped projection 20 of the bearing shell engages in a correspondingly designed recess 21 in the transverse wall 9 of the holder housing 1, as can be seen in particular from the illustration in FIG. 11.
