Definitions

  • the present invention relates to a door lock arrangement and a door for an automobile, for instance a front door. It further relates to an automobile, especially a passenger car.
  • Automobile types typically have to pass security tests, like for example crash tests, to be permitted in the European market.
  • front door side crash tests the doors must not be delatched and opened while the vehicle has been crashed with side pole.
  • the used pole has for example a weight of 30 kg and a velocity of 10 m/s.
  • the outer handle moves and hits to the multi-functional bracket (MFB) and starts to rotate or get damaged.
  • MFB multi-functional bracket
  • the counterweight may rotate, may pull the latch release cable and may delatch the door.
  • the test failed and the vehicle cannot be sold in any European market because of this regulation failure.
  • an internal requirement says that the latch must be engaged to its striker in either the primary or secondary latched position after side pole and barrier test.
  • the door latch and striker must remain attached to the vehicle and doors are closed, no damage on occupant.
  • a vehicle had a side impact failure because of insufficient clearance between the outer handle hook -counterweight and adjacent parts on front doors.
  • the CAE showed that, when the pole crashes to the outer panel, it bends and the outer handle moves towards MFB. When the door gets deformed and the outer handle touches the MFB, the handle starts to rotate so the counterweight starts to rotate or gets broken. When the counterweight rotates or it is damaged, it pulls the latch release cable and the latch delatches. If the latch is delatched from the striker, the crawl loses from the striker and the door opens unintentionally. On side crash test, the latch crawl must not release from the striker and stay in an engaged position.
  • the inventive door lock arrangement for an automobile comprises an outer handle, a handle reinforcement component, a support bracket and a latch release mechanism.
  • the latch release mechanism comprises a counterweight.
  • the outer handle and the counterweight are connected to the handle reinforcement component.
  • the handle reinforcement component and the latch release mechanism are connected to the support bracket.
  • the support bracket comprises a main body portion and at least two crash bumper portions. Each crash bumper portion protrudes from the main body portion.
  • the main body portion comprises a cut out portion or clearance or recess located between the at least two crash bumper portions, for example between a first crash bumper portion and a second crash bumper portion.
  • At least part of the counterweight is located between the crash bumper portions, for example between the first crash bumper portion and the second crash bumper portion.
  • the inventive door lock arrangement has the advantage that it prevents a rotation of the counterweight in case of a crash situation, since the counterweight can translate into the cut out portion or clearance or recess located between the crash bumper portions.
  • the crash bumper portions stabilize the handle reinforcement component and avoid the handle from being pressed against the counterweight.
  • the inventive door lock arrangement prevents damage and rotation of counterweight and avoids delatching doors on side crash pole test.
  • the present invention is advantageous in that the crash bumper portions hold the outer handle or adjacent parts and no part can touch or crash to the handle reinforcement component, the counterweight or the outer handle hook. Due to the crash bumper portions the support bracket, for example MFB, and adjacent parts move together with save distance between each other. In a crash test situation the door will not open because the outer handle or the counterweight cannot rotate.
  • the present invention provides a very cheap and useful solution for side crash test when compared other solutions.
  • the support bracket may be a multifunctional bracket (MFB).
  • the crash bumper portions and the main body portion can be made in one piece or the crash bumper portions can be separate components, which are connected to the main body portion.
  • the support bracket or the main body portion and/or at least one crash bumper portion, preferably all crash bumper portions can comprise flexible or bendable material, for instance plastic material.
  • the bracket or the main body portion and/or at least one crash bumper portions, preferably all crash bumper portions are made of flexible or bendable material, for instance plastic material. This allows for bending the support bracket or the main body portion and/or at least one crash bumper portion in case of force acting on the respective portion caused by a crash.
  • the main body portion preferably comprises means for connecting at least one door lock component to the support bracket, for instance for connecting the handle reinforcement component.
  • part of the handle reinforcement component is located adjacent to the crash bumper portions such that the crash bumper portions prevent a movement of the handle reinforcement component in a horizontal direction.
  • part of the handle reinforcement component is located adjacent to the crash bumper portions such that the crash bumper portions prevent a movement of the handle reinforcement component in a horizontal direction, especially towards the counterweight and/or towards a passenger cabin.
  • the handle comprises a hook with a length direction and each crash bumper portion may protrude from the main body portion in a direction parallel to the length direction of the hook.
  • the door lock arrangement may comprise a horizontal direction and each crash bumper portion may protrude from the main body portion in horizontal direction.
  • the horizontal direction may run horizontally, especially when the door lock arrangement is mounted in a door and the door is mounted in an automobile.
  • the horizontal direction may run parallel to the length direction.
  • a first horizontal direction and a second horizontal direction can be defined, wherein the first horizontal direction and the second horizontal direction run perpendicular to each other and the vertical direction runs perpendicular to the first horizontal direction and perpendicular to the second horizontal direction.
  • At least part of the counterweight may be located between the crash bumper portions in the first horizontal direction and/or in the second horizontal direction and/or in the vertical direction.

  • the horizontal direction runs parallel to the length direction of the outer handle hook and/or to the bottom edge of the window.
  • each crash bumper may protrude in horizontal direction.
  • the counterweight is advantageously located between the at least two crash bumper portions in vertical direction. This allows for a movement of the counterweight into the cut out portion of the main body portion between the crash bumper portions, especially in case of a crash situation, and avoids unintentional rotation of the counterweight.
  • At least part of the counterweight may be located between the crash bumper portions in vertical direction and/or in a first horizontal direction and/or in a second horizontal direction, which is perpendicular to the vertical direction and perpendicular to the first horizontal direction.
  • the inventive automobile comprises a door as previously described.
  • the inventive automobile has the same advantages as the inventive door lock arrangement and the inventive door for an automobile.
