Definitions

  • the invention relates to a tailgate linkage for motor vehicles according to the preamble of claim 1.
  • Tailgate In the course of the design of modern combination vehicles with ever deepening Cargo space is unhindered and convenient access to the innermost Areas of the cargo space only possible or accessible if the Tailgate can be pivoted upwards so that the vehicle user no longer needs to bend over directly to the rear wall of the To approach the vehicle.
  • Such Increasing the opening angle of a tailgate offers in constructive Regarding no particular difficulties.
  • On the other hand are in the completely open position of the tailgate flaps very steeply for closing smaller people with difficulty.
  • 2,388,021 there is a leaf spring fastened on the body side and arched eccentrically to the hinge axis of the lid linkage, and a trunk spring cooperating with it via the second part of its opening movement attached inhibitor roller is provided in order to initially achieve a braking with increasing opening angle of the trunk lid.
  • the locking roller is assigned a locking recess in the curved leaf spring, in such a way that the locking roller engages in the locking recess of the leaf spring when the trunk lid is fully open and the trunk lid is locked in its fully open position.
  • Both known types of locking devices for the trunk lid of vehicles are characterized by a large need for installation space, which is not available in the area of the vehicle roof.
  • the invention is therefore based on the object of a tailgate linkage to create according to the preamble of claim 1, which allows for easy access to the cargo hold of the tailgate in at least one partial opening position.
  • the tailgate linkage is thereby ensured that the Gooseneck-shaped curvature of the hinge arm in the side view approximately U-shaped or V-shaped and with regard to the spreading of the two legs of the V-shape is designed in such a way that the distance between the locking mark arrangement Area of the hinge arm to the swivel axis in a predetermined Opening angle range of the tailgate, in particular an opening angle range of about 60 ° and more, reduced to a predetermined level.
  • the latching member of the locking device is arranged on the free end of a non-rotatable and, in the direction radially directed to the swivel axis, on the fixed, vehicle-side swivel half attached to the support arm.
  • the support arm carrying the locking member is advantageously fastened together with the hinge arm by means of a stepped rivet to the fixed, vehicle-side swivel joint half and has a given distance at a predetermined partial opening position of the tailgate, for example that at a first partial opening angle of the tailgate of 60 ° Hinge arm trained locking mark arrangement to the swivel axis corresponding length.
  • the one for locking the tailgate in one or more partial opening positions required holding force of the locking device is in an appropriate Embodiment applied in that the support arm carrying the locking member is formed by a spring arm, the one arranged at its free end interacting with the locking mark formed on the hinge arm Locking member expediently formed by a locking roller or a locking roller is.
  • a particularly simple design of the support arm as a spring arm results further from the fact that the support arm from a blank of a spring steel sheet exists, for the purpose of its determination on the fixed vehicle side Swivel joint half is also provided that it is in the area of its definition on the fixed vehicle swivel half with two ears placed perpendicular to its plane.
  • Such a design Support arm can be easily and without the need for additional Fastening elements by means of a corresponding recesses in the ears penetrating perpendicular to its plane and as rivets trained hinge pin together with the hinge arm, but are non-rotatably attached to the vehicle-side swivel joint half, whereby for the rotationally secure fixing of the support arm expediently further it is provided that the recesses in the parked ears of the support arm have a non-circular shape and the hinge pin in its associated length ranges one to the outline shape of the recesses in the parked ears of the support arm recesses complementary cross-sectional shape having.
  • One way to optionally determine the tailgate in different Partial opening positions is opened according to the invention in that the on Hinged arm-formed detent mark arrangement at least two in the pivoting direction successively arranged detent marks comprises, the detent marks by successively and adjacent to each other as well each a survey between partially circular impressions in the surface of the hinge arm opposite the swivel joint axis are formed.
  • This is due to exclusively arched transitions marked training of successively arranged locking marks ensures a smooth transition from locking mark to locking mark and thus an almost completely noiseless movement of the locking device.
  • the swivel joint for the articulation of a tailgate not shown in the drawing consists of a first swivel joint half 1 fixedly attached to the vehicle body (also not shown in detail) and a second swivel joint half 2 fastened to the tailgate, the second swivel joint half being curved by a gooseneck and is formed in the horizontal projection approximately V-shaped angled hinge arm 2.
  • the two swivel joint halves are pivotally connected to one another by means of a hinge bearing bolt 3.
  • the locking device structurally combined with the swivel joint 1 to 3 consists of a spring-loaded latching element supported on the one swivel joint half 1 and aligned radially to the hinge bearing bolt 3 and a detent mark arrangement 5 formed on the surface 4 of the hinge arm 2 opposite the swivel joint axis 3.
  • a locking roller 6 locking member is supported via a support arm 7 against the hinge bearing pin 3 and thus against the fixed swivel joint half 1.
  • the support arm 7 consists of a cut of a spring steel sheet or wire, which is angled in its longitudinal direction at 8 and provided at its end opposite the latching roller 6 with ears 9 placed at right angles, and is by means of recesses arranged in its ears 9 with a plan shape deviating from the circular shape complementary cross-sectional shape having longitudinal sections of the hinge bearing bolt 3 designed as a step rivet in a position radially aligned with the swivel joint axis 3 in a rotationally fixed manner on the fixed hinge joint half 1.
  • the support arm 7 is provided with a projection 13 projecting beyond its connection to the hinge bearing pin 3, via which it interacts with an abutment formation 14 arranged on the fixed swivel joint half 1.
  • the support arm 7 has a length corresponding to that given a predetermined partial opening position of the tailgate, for example the distance of the detent mark arrangement formed on the hinge arm 2 to the swivel joint axis 3 given at a first partial opening angle of the tailgate, at the same time that with a predetermined partial opening position of the tailgate, For example, given a partial opening angle of the tailgate of 60 °, the distance between the detent mark arrangement formed on the surface of the hinge arm 2 facing the swivel joint axis 3 is determined by the spreading of the legs 11 and 12 of the V-shaped bend of the hinge arm 2.
  • the detent mark arrangement formed on the hinge arm 2 comprises three detent marks 15, 16 and 17 arranged successively in the pivoting direction, the detent marks 15, 16 and 17 being arranged by successively and adjacent to one another and each having an elevation 18 between them including partially circular impressions in the surface of the swivel joint axis opposite Hinge arm 2 are formed.
  • the hinge arm 2 is also provided with a bracket 19 for connecting a gas spring, not shown in detail.
