Definitions

  • the invention relates to a door arrester for motor vehicle doors, consisting of a provided with locking marks, pivotable on a door arrangement part, door or door spar, hinged door holding rod and a two opposite, arranged under a cushion of spring-elastic material applied spring load at least in the area of the locking marks of the door holding rod, rotatably mounted in brake bodies, which are each supported by spring cages, the holder housing, the holder housing forming a hollow body which is essentially closed except for the openings for the door holding rod, and wherein within the holder housing at least on the side of the holder housing, which is between the brake bodies and the end of the door holding rod that is to be articulated is a front of the brake bodies arranged at least on the surfaces of the door holding rod that cooperate with the brake bodies Dig-fitting, elastically deformable is arranged by a dirt scraper formed by the scraper ring comprising the door neck rod.
  • Door arrestors for motor vehicle doors must be able to apply consistently high braking and holding forces over a very long service life and are also completely noise-free, while being completely maintenance-free. The fulfillment of this requirement is made more difficult by the fact that dirt and abrasion accumulate on the door holding rod over time, as a result of which the surface quality is changed.
  • the movement of the door holding rod through the holder housing required for the operation of the door arrester also has the consequence that a considerable amount of dirt, deposits and abrasion and, not least, water is conveyed into the interior of the holder housing over the course of time, which is particularly the case with such door arresters whose braking and holding bodies are formed by rolling elements mounted in cages, sooner or later leads to the fact that the rolling rolling elements can move on the one hand due to rust formation and on the other hand by clogging the stomata in their bearings is lifted inside the cages and the brake body now rubs like rigid brake pads over the door support rod, which necessarily leads to a highly undesirable noise formation in the door retainer.
  • the bearings in other ways rotatably mounted brake or.
  • Holding bodies become sluggish due to increasing contamination, so that here too the roll or brake mobility ultimately Holding body is at least partially canceled.
  • the braking or. Holding body but also the consequence that the braking or at least partially grinding over the door support rod, which usually consist of hardened iron material. Holding bodies in the softer surface of the door holding rod generate inlet grooves, chatter marks and the like. Surface changes on the door holding rod, so that gradually, in addition, a change in the braking or holding force applied by the door arrester is also increasingly established.
  • DE-U-8816226 has already proposed for a door arrester of the type generally described at the outset to limit the bearing surfaces on the brackets receiving and supporting the braking bodies designed as rolling elements to a maximum of half the circumference of the braking rolling elements and
  • special restraining means in the form of radially inwardly projecting lugs or the like are to be provided, which, with a suitable design, at the same time also offer the possibility, at least in the area of the bearing surfaces assigned to the brake bodies, to completely exclude or prevent any deposition of dirt or abrasion self-cleaning of the storage areas cause.
  • the invention is therefore based on the object of providing a door arrester of the type mentioned at the beginning for motor vehicle doors, which is provided with means for preventing the penetration of dirt, deposits or water into the interior of the holder housing without additional manufacturing or assembly effort.
  • the dirt scraper or wipers are each connected via resilient support walls to the cushions arranged within the holder housing made of rubber-elastic material, the respective scraper ring and the thin support wall carrying this together with the spring load for the brake body Cushions are made in one piece from rubber-elastic material.
  • the design of the scraper rings which includes the door holding rod, and on the other, the one-piece design with the cushions made of rubber-elastic material arranged within the holder housing, is advantageous, since in addition to completely or at least almost completely keeping the interior of the holder housing free from dirt, water or other substances Deposits collecting on the door support rod and above all achieved that the dirt wipers together with the necessary and to be installed internals of the holder housing and thus manufactured without additional effort and can be installed more or less automatically.
  • the first passage of the door holding rod through the holder housing usually takes place when the door is opened, so that in the simplest case it can be sufficient to wipe off the dirt deposited on the door holding rod when the door holding rod opens for the first time when the door is opened dipped into the holder housing, especially since no special dirt deposits are to be expected on the door support rod during the short opening time of the vehicle door. It is more expedient and safer, however, to free the door holding rod from dirt and deposits, in particular water, in both directions of movement before immersing it in the holder housing.
  • the wiper rings are provided with sharp-edged wiper lips or wiper edges resting on the door holding rod and are designed to be elastically deformable within certain limits, such that they remain in constant contact with the surfaces of the Door support bar can adjust their diameter changes.
  • the scraper ring assigned to the passage opening arranged in the housing cover of the holder housing is connected by means of an annular support wall directly to the cushions consisting of a rubber-elastic material and is formed with the same material, with regard to the scraper ring assigned to the passage opening in the holder housing bottom, it can be provided that the thin rings assigned to this scraper ring Support walls the cages supporting the brake body are comprehensively trained and arranged.
  • the wiper rings provided they cover the entire opening width of the passage openings, can also be connected to the cushions made of elastic material or the cages via connecting means formed by spring tongues or the like, since the one-piece design of the wiper rings with the cushions made of elastic material only reduces the required individual parts and to facilitate assembly and a continuous support wall outside the overlap with the through openings of the holder housing is not required for this.
  • a door arrester shown schematically in its entirety in FIG. 1, comprises a door holding rod 1 which is pivotally articulated on a door arrangement part, door or door pillar and which, at its free end, is provided with a stop buffer 2 forming the opening end stop of the door and bulges 3 forming latch marks over its length is and a holder housing 4 with brake or rotatably arranged therein against a spring load perpendicular to the plane of movement of the door holding rod 1. Holding bodies 5.
  • the passage of the door holding rod 1 through the holder housing 4 is assigned a passage opening 6 in the bottom 7 of the holder housing 4 and a passage opening 8 in the cover 9 of the holder housing. The braking or.
  • Retaining bodies 5 are designed as rollers or rollers and are freely rotatably supported in cages 10 such that they roll against the bulges 3 at least when the door retaining rod 1 passes through the holder housing 4.
  • the cages 10 are supported on the one hand at 11 tiltable in the holder housing 4 and on the other hand acted upon by cushions 12 made of rubber-elastic material with a spring load such that the cages 10 can only perform a tilting movement against the spring load of the cushions 12, whereby the spring force at least in the area thereof Bulges as braking or. Holding force is transmitted to the door support rod.
  • the scraper ring 13 is bead-like and is provided with a scraper edge 15, by means of which it abuts the surface of the door holding rod 1 in a line.
  • the cage 10 consists of two spaced apart bowl-shaped support bodies 41 and 42 for the tiltable support of the cage 10 and a housing cover 90.
  • the brake or. Cages 10 accommodating the holding body 5 and freely rotatably supported are supported here at 11 likewise in the supporting bodies 41 and 42 and can be tilted about axes parallel to the plane of movement of the door holding rod 1 and acted upon by cushions 12 made of a rubber-elastic material with a spring force.
  • the two openings 6 and 8 of the holder housing 4, which are located opposite one another and each assigned a direction of movement of the door holding rod 1, are each assigned a wiper ring 13 or 16, the wiper ring 13 being connected to the cushions 12 made of rubber-elastic material via a thin-walled elastic support wall 14 or is formed in one piece with these and the support wall 14 covers the opening width of the passage opening 8 of the holder housing 4 lying outside the wiper ring 13.
  • Holding bodies 5 opposite scraper ring 16 arranged in front is also bead-shaped and provided with a scraper edge 15, by means of which it is linear on the door holding rod 1 is present.
  • the scraper ring 16 is connected or formed in one piece via thin-walled support walls 17, the support walls 17 engaging under the free space remaining between the shell-shaped support bodies 41 and 42 and thus supplementing them to form a substantially closed holder housing.
  • the cages 10 are only tiltably supported in their corner regions at 11 on the shell-shaped support bodies 41, 42, while they also have recesses or depressions for receiving the thin-walled support walls 17.
  • the shell-shaped support bodies 41 and 42 are parts of a one-piece housing 4.
