Definitions

  • the invention relates to a spring support for a motor vehicle door arrester, in which a rigid door holding rod, which is pivotably articulated on a door arrangement part, door or door pillar, penetrates a cold housing rigidly fastened to the other door arrangement part by means of a support arm arranged on the free loading arm and on this via a support arm supported torsion bar spring is freely rotatably mounted load roller.
  • 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 held or supported within the holder housing via its shaft part and also via its load arm , in such a way that its free load arm is deflected by the holder housing during the passage of the locking recesses in the door holding rod.
  • this deflection of the load arm of the door holding rod also causes the shaft part of the torsion bar spring to rotate relative to the regions of the holding housing which support it, which results in a noise development within the door arrester, which increases with the operating time of the door arrester and thus with increasing rebound the support of the shaft part of the torsion bar spring becomes larger.
  • 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 received in an elongated hole recess of the holder housing folded from a sheet material blank and its shaft part is supported within the holder housing by means of a bearing shell made of self-supporting and maintenance-free bearing material, the bearing shell being additionally preselected by mechanically acting holding means is held in position within the holder housing between the shaft part and the support arm.
  • 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 door holding rod 3 is formed by a sheet metal material cut and with it Back surface 9 provided oppositely arranged rest areas 4.
  • 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 in an S shape 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 between circuit 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.
