Definitions

  • the invention relates to a motor vehicle door arrester, consisting of a holder housing rigidly attached to a door arrangement part, door or door pillar, and a holder housing which passes through it and is pivotally articulated on the other door arrangement part about an axis parallel to the door hinge axis, provided with brake and detent marks, in which in the Holder housing two with the brake or locking marks of the door holding band designed as rollers or rollers are provided, one of which is rotatably mounted as an abutment roller about a fixed axis in the holder housing and the other on a pivotally suspended in the holder housing and against a spring load perpendicular to the plane of movement of the door holding band pivotable holder is displaced, the holder being loaded by means of a torsion spring supported against the holder housing, and wherein the two rollers, abutment roller and loading roller interacting with the door retaining band, a ls essentially smooth-surface rollers are executed.
  • a door arrester of this type is known in principle from EP-A-445 417 (state of the art according to Article 54 (3) EPC), however in this known door arrester at least one of the brake bodies cooperating with the broad side of a door retaining band formed from a flat material blank is through a rolling element of small diameter, in particular a steel needle.
  • the brake body which is designed in particular as a steel needle, is mounted without an axle in the holder which is pivotally suspended in the holder housing and which can be pivoted counter to a spring load perpendicularly to the plane of movement of the door holding band. Lateral guidance or support of the door holding band within the holder housing is neither provided nor available.
  • the two brake bodies which cooperate with the narrow sides of a door holding rod and are designed as rollers and which are formed as rollers, have a relatively large diameter, which initially results in a relatively large-volume construction of the door arrester.
  • a disadvantage of this type of door arrester is in particular that the rollers only interact with the narrow sides of the door retaining band, so that the door retaining band is not guided over its entire length unless special effort is required for the design and storage of the rollers that there is to a considerable extent the risk that, as a result of installation or manufacturing tolerances in the operation of the door arrester, an inclination of the door holding band to the rollers occurs, which in turn results in the formation of inlet grooves on the rollers and in the second place the development of noise .
  • the invention is therefore based on the object of improving a door arrester of the type mentioned at the outset in such a way that sources of noise are largely excluded and an exact guidance of the door retaining band is ensured even in series production and series assembly, without the production expenditure or the construction volume of the door arrester thereby being increased.
  • the design of a door arrester according to the invention thus allows a safe and exact guidance of the door retaining band with a simultaneous reduction in the manufacturing effort required for the door arrester, since as a result of the guidance of the door retaining band on the anyway required holder for the load roller, a simple design of the rollers can be chosen and on the other Side of the total manufacturing effort for the holder also not increased.
  • Simplification in the manufacture of the door arrester is further achieved in that the holder housing is smooth-walled overall, i.e. can be formed with smooth side walls.
  • the holder carrying the load roller is designed as a molded part, in particular an injection molded part, and is coated with an abrasion-resistant plastic material at least in the region of the inner surfaces of its legs, but preferably consists entirely of an abrasion-resistant plastic material.
  • the holder is extended in the direction of movement of the door holding band beyond the bearing of the load roller and the legs of the holder in this area are provided with lugs that at least partially overlap the height of the narrow sides of the door holding band, such that the side guide of the door holding band is arranged at a distance from the load roller.
  • a guidance of the door holding band over a greater length results from the fact that the legs of the holder rest against the narrow sides of the door holding band over a length corresponding at least to the diameter of the loading roller.
  • the legs of the holder rest in the direction of movement of the door holding band over a length range exceeding the amount of the diameter of the loading roller on the narrow sides of the door holding band.
  • the door retaining band consists of a flat material strip provided with at least one coating made of an abrasion-resistant plastic material, but preferably of a reinforcement provided by a metallic flat material strip provided with openings and a molded plastic body that forms the detent marks.
  • the door arrester in conjunction with a roller-shaped configuration of the abutment and loading roller, at least one of the broad sides of the door holding band is provided with elevations forming brake or detent marks, and that the holder, which is pivotably suspended in the holder housing, is attached to a stationary part in the holder housing arranged bearing axis is suspended and loaded by a torsion spring, the latter assigned load spring tangentially to the circumference of the load roller mounted in it acts on the pivotable holder, the spring loading the pivotable holder being formed by a support arm supported against the holder housing and acting on it via a central load arm, the windings of which are concentric with the bearing axis of the pivotable holder are arranged.
  • the two rollers, abutment roller and loading roller are mounted on the axle assigned to them by means of a bearing bushing and that they are supported on both sides by a seal arranged at the end, e.g. an O-ring seal or a lip seal is sealed.
  • the invention is not limited to a special design of the door arrester with regard to the design of the load spring, rather it can equally be provided that the load on the holder which can be pivotally suspended in the holder housing is the load arm of a U-shaped or S-shaped, via a support arm, in particular on the bearing webs of the holder housing is assigned supported torsion spring, wherein the support arm of the torsion bar spring fixed to the bearing webs of the holder housing can simultaneously form the axis supporting the pivotable holder.
  • the motor vehicle door arrester essentially consists of a holder housing 1 and a door holding rod 2 passing through it.
  • the holder housing 1 is formed from a one-piece flat material blank and has two fastening flaps 4 adjoining one another which project up and which are connected to one another by means of a crosspiece 4 and which are connected by means of a crosspiece 4 Holder housing 1 is struck by means of bolts 5 on the associated door arrangement part, not shown in the drawing.
  • an abutment roller 7 having a smooth circumference is rotatably mounted about a fixed axis by means of a bearing pin 6 designed as a head pin.
  • the abutment roller 7 is guided within the smooth-walled holder housing 1 by means of spacer blocks 10, which are formed from a plastic material and rest on its strings 9. Opposing the abutment roller 7 with respect to the door holding band 2 is suspended by means of a holder 12 suspended in the holder housing 1 about a fixed axis 11 parallel to the axis of rotation of the abutment roller 7, a loading roller 13 is adjustably suspended perpendicular to the door holding band 2.
  • the holder 12 is formed as an injection molded part made of an abrasion-resistant plastic material and has a U-shaped cross-sectional shape comprising two legs 14 and 15 and a transverse web 16.
  • a bearing bore 17 is provided in the holder 12, via which it is pivotably mounted on a bearing pin 18 which passes through the two side webs 3 of the holder housing 1 and forms the bearing axis 11.
  • the load roller 13 is mounted in the legs 14, 15 of the holder 12 by means of bores 19 and a bearing pin 20.
  • the holder 12 is by means of a loading spring designed as a coil spring 21, the windings 22 of which are arranged on both sides of the longitudinal center of the door arrester on the bearing journal 18 and whose central loading arm 23 engages by means of a guide recess 24 arranged there on the crossbar 16 of the holder 12, in the direction of the door holding band spring-loaded.
  • the two legs 14 and 15 of the holder 12 are extended in the direction of movement of the door holding band 2 beyond the bearing axis 20 of the loading roller 13 and provided with noses 25 directed perpendicular to the plane of movement of the door holding band 2, via which they partially adjust the height of the narrow sides 26 of the door holding band 2 reach over such that the door retaining band 2 is guided on the inner surfaces 27 of the legs 14 and 15 of the holder 12.
  • the door holding band 2 consists of a reinforcement 29 formed by flat material blank provided with openings 28 and a molded part 30 formed of plastic, the molded part on one side of the door holding band 2 having the locking recesses 31 assigned to the loading roller 13, while its the Abutment roller 7 facing side 32 is smooth.
  • the abutment roller 7 and the loading roller 13 are mounted in the embodiment shown in FIG. 3 by means of bearing bushes 33 on the bearing journals 6 and 20 assigned to them, the bearing being sealed on both sides by means of a seal 34.
  • the seal 34 which is shown only schematically in the illustration in FIG. 3, can either be a lip seal 35 in accordance with the detailed illustration in accordance with FIG. 9 or else as an O-ring seal 36 or a radial lip seal in accordance with FIGS. 10 and 12 37 be formed. Specifically, in the embodiment shown in FIG.
