Definitions

  • An actuating device placed inside a motor vehicle body is generally provided for actuating and opening motor vehicle hood locks and in particular motor vehicle front hood locks. This can, for example, work manually via a linkage or a Bowden cable on a release lever to open the locking mechanism.
  • the actuation device may be a handle or a loop for manual actuation.
  • a switch for the electrical loading of the release lever can also be actuated. In this case, an electric motor drive is assigned to the release lever.
  • the limiting arm forming the limiting extension is mounted coaxially on the pawl.
  • the pawl and the limiting arm lie flat on top of each other.
  • the already mentioned damping element is provided, which is rotatably coupled to the limiting arm via a coupling tooth. If, for example, the associated front flap is closed with momentum, the pawl moves against the limiting extension. If the surface contact between the delimiting extension and the pawl is removed, the delimiting extension can move back with a delay.
  • the limiting extension steps out of the path of movement of the rotary latch and enables the rotary latch to be pivoted into the avoidance position or overtravel position.
  • the pawl 4 is equipped with a limiting extension 8 assigned to the rotary latch 3 .
  • the limiting extension 8 ensures that closing movements of the rotary latch 3--according to the exemplary embodiment in the clockwise direction about the associated axis 6--are limited.
  • the delimiting extension 8 provides what is known as breakdown protection, as will be explained in more detail below.
  • the limiting extension 8 represents a fixed or integral part of the pawl 4 within the scope of the invention.
  • the pawl 4 is additionally equipped with at least one ratchet tooth 4a, 4b.
  • the pawl 4 has a first ratchet tooth 4a and a second ratchet tooth 4b.
  • the first locking tooth 4a is arranged on the front side of the locking pawl 4, while the second locking tooth 4b is designed as a projection offset in the direction of the axis 7 of the locking pawl 4 relative to the first locking tooth 4a.
  • the first locking tooth 4a is primarily relevant for the following considerations.
  • the rotary latch 3 in turn has at least one locking tooth 9, 10.
  • a pre-locking tooth 9 and a main locking tooth 10 are implemented. In principle, however, it is also possible to work with only one of the two locking teeth 9, 10.
  • the rotary latch 3 is additionally equipped with a spring 12 which acts on the rotary latch 3 in the opening direction.
  • This spring 12 ensures that the rotary latch 3 starting from the puncture protection position after 2 is applied in the opening direction, that is, according to the embodiment in the counterclockwise direction.
  • the rotary latch 3 or its rocker 11 is released from the limiting extension 8 on the pawl 4 as soon as an operator no longer acts on the motor vehicle front hood 1 . Because then the breakdown protection position 2 leaving.
