Definitions

  • the present invention relates to a latching device for a vehicle hinge, a vehicle hinge comprising such a latching device, as well as a method of using such a latching device.
  • the invention relates to the field of the automobile industry.
  • motor vehicles are generally temporarily provided with a temporary door stop fitted on the hinges of the doors of these vehicles, in order to keep the doors in the open position during the passage of the bodies being ironed, cataphoresed and painted. .
  • the door stop is temporary and is then removed from the vehicle.
  • a known hinge of a motor vehicle comprises a hinge fixed on the body of the vehicle and a movable hinge fixed on the door of the vehicle, the movable hinge was pivotally mounted on the fixed hinge via a pivot shaft of the hinge, so as to allow the door to pivot over an angular sector of approximately 70° between its closing orientation and its opening orientation.
  • the door stop is designed to be slipped onto the pivot shaft while being fixed in rotation around this shaft on a movable hinge.
  • Known door stops are generally made of steel and form an elastic blade which is able to snap onto the fixed hinge when the movable hinge is oriented in the open position, so as to maintain the movable hinge and the door in this open position.
  • a retaining nut is generally provided to maintain the door stop in translation along the pivot shaft while nevertheless allowing the door stop to pivot around the pivot shaft.
  • FR 2 916 471 A1 describes a temporary door stopping device comprising a pin, mounted on one of the knuckles of the hinge, and an elastic metal hooking member of generally flat shape.
  • the elastic attachment member is mounted on the axis of the hinge while being linked in rotation to the other hinge by a folded tab.
  • the elastic hooking member comprises an arm cooperating with the surface of the pin by a retaining notch to temporarily hold the hinge in the open position.
  • Known door stops have the main disadvantage of requiring heat and surface treatments of the steel which constitutes them, so as to be able to withstand the mechanical stresses imposed by the hinge, as well as the various treatments carried out on the vehicle during its manufacture.
  • the repeated clicking and unlatching of known door stops causes wear of the latter, likely to lead to the formation of particles, namely metal filings each time the hinge opens and closes.
  • the implementation of cataphoresis or electroplating on the vehicle results in the deposition of particles on the surface of the metal door stops.
  • the invention aims to resolve the drawbacks of the aforementioned prior art, by proposing a new latching device that is particularly easy to manufacture and does not generate particles during its use.
  • the subject of the invention is a latching device according to claim 1.
  • the manufacture of the latching device is facilitated, to the extent that the absence of metallic material makes it possible to avoid carrying out particular heat or surface treatments, but nevertheless leads to the production of a device particularly wear-resistant and with sufficient mechanical properties to be able to reliably fix the second knuckle in rotation relative to the first knuckle by snap-fastening.
  • the latching device of the invention does not generate filings by abrasion, being devoid of metallic material, so that it is not necessary to clean the vehicle during or after its manufacture.
  • the invention also relates to a vehicle hinge defined in claim 5.
  • the invention also relates to a method defined in claim 9.
  • the hinge comprises a permanent assembly comprising the first knuckle, the second knuckle, the pivot shaft and the rings by means of which one of the knuckles is mounted on the pivot shaft, the latching device is symmetrical with respect to a main plane perpendicular to a mounting axis defined by the mounting hole, and the latching device can be attached to the pivot shaft, which the assembly remains in place either a left hinge assembly or a right hinge assembly symmetrical with respect to the left hinge assembly.
  • the hinge shown on the figures 1 to 4 is generally designated by the reference sign 1.
  • the hinge 1 comprises a frame hinge 3, an opening hinge 5, a pivot shaft 7 and a latching device 9.
  • the opening hinge 5 corresponds to a first knuckle, and the knuckle of frame 3 to a second knuckle.
  • the hinge 1 is designed to equip a motor vehicle, such as a car or utility vehicle. Hinge 1 is nevertheless suitable for equipping other types of vehicle, as long as these vehicles are equipped with at least one hinged door.
  • the hinge 1 constitutes a connecting element of a hinged door of the vehicle, of the passenger door or tailgate type, with a body of the vehicle.
  • the frame hinge 3 is designed to be fixed to the body of the vehicle via fixing holes 11 provided in a support plate 13 of the frame hinge 3.

  • the pivoting orifices 43 and 45 of the knuckle 5 are respectively mounted on the axial parts 59 and 61 of the rings 47 and 49, so that the knuckle opening 5 is pivotable around the axis leg 35, while the collar 53 is interposed between the branch 17 and the leg 37.
  • the opening hinge 5 being thus pivotally mounted on the frame hinge 3 via the shaft 7, this hinge 5 can move between an opening orientation, shown on the figure 4 , in which the central part 27 abuts against a boss 63 of the stop plate 19, and a closing orientation, in which the opening hinge 5 is pivoted around the axis X1 relative to the frame hinge 3 so that part 27 is away from boss 63.
  • the angular difference between the opening orientation and the closing orientation amounts to, for example, approximately 70°.
  • the opening orientation of the hinge 1 corresponds to an opening orientation of the vehicle door, in which the door is partly moved away from the body to allow the introduction into the body of a person or a object via a passage opening of said box.
  • the closing orientation of the hinge 1 corresponds to a closing orientation of the vehicle door, in which the vehicle door is folded against the body so as to close the passage opening of the latter.
  • the frame hinge 3, the opening hinge 5, the pivot shaft 7 as well as the rings 47 and 49 are preferably made of metal, and form a "permanent" assembly, remaining on the vehicle at the end of the manufacture of the latter.
  • the latching device 9 constitutes an attached part on the aforementioned permanent assembly of the hinge 1.
  • the device 9 is intended to be equipped on the assembly only during manufacture of the vehicle, in order to temporarily hold the hinge 1 and the door in their opening orientation. During, or after, the manufacture of the vehicle, the latching device 9 is detached from the vehicle concerned. The device 9 is then optionally used for another vehicle being manufactured.

  • the latching device 9 can be slipped onto the end part 69 via the orifice 67 axially along the axis X1, so as to be retained axially along the axis the main plane P9 is orthogonal to the axis X1. Thanks to the adjusted nature of the diameter of the mounting hole 67, the latching device 9 can advantageously be mounted without a nut on the shaft 7. Thus, any risk of loosening a retaining nut is avoided.
  • the end part 69 is oriented downwards, so as to project from below the hinge 1. Consequently, the end part 69 is located outside the visual field of a user of the vehicle, thus being hidden by the knuckles 3 and 5.
  • the latching device 9 is placed on the underside of the hinge 1.

  • the latching hook 73 thus constitutes a latching member configured to be latched with the knuckle 3 when the hinge is in open orientation.
  • the latching hook 73 When the latching hook 73 is latched with the pin 81, the latching device 9 and the frame hinge 3 are fixed in rotation relative to each other around the axis X1.
  • the opening hinge 5 is therefore also fixed in rotation relative to the frame hinge 3, so that the vehicle door is latched in opening orientation.
  • the latching of the device 9 of the figures 1 to 4 is carried out thanks to a deformation of the device 9 in a direction parallel to the plane P9.
