Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism with a catch and pawl, and with a locking unit which at least in its "locked” position suppresses or prevents an automatic opening of the locking mechanism.
  • the usually automatic opening of the locking mechanism is achieved or shown that the catch is regularly transmitted spring assisted in its open position as soon as the pawl is lifted from the catch.
  • Such motor vehicle door locks are known in many ways. These often have a closing device today, as described in EP 1 319 780 A1.
  • a motor-adjustable clutch carrier is realized, on which a clutch lever with a coupling nose is arranged adjustable.
  • the coupling nose of the clutch lever engages non-positively in a coupling catch of the rotary latch and transfers it to its closed position or in an intermediate position before the closed position.
  • the coupling nose of the coupling lever remains in the aforementioned coupling catch of the rotary latch.
  • the coupling catch is designed so that after lifting the pawl from the main locking position of the rotary latch by a reversal of rotation of the motor drive coupled to the clutch carrier via the clutch lever rotary latch is adjusted by motor to its open position.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock in a functionally simple manner so that at least the "locked" position of the locking unit can be represented easily and with simple means.
  • a supplementary incident or already sunken auxiliary pawl prevents the automatic opening of the locking mechanism.
  • the already sunken or incidental additional pawl ensures that the position "locked” of the locking mechanism is taken reliably and reliably. Because with the help of the additional pawl, the self-actuated opening of the locking mechanism is at least prevented when the pawl is lifted from the catch or is and is the position "locked" of the locking mechanism or the locking unit to be displayed.
  • the invention in the "locked" position of the locking unit does not specifically prevent lifting of the pawl of the rotary latch. Rather, the inventive
  • Locking unit virtually the same functionality in the "locked” position as in the "unlocked” position. With the only difference that in
  • Locking position incident additional pawl prevents the automatic opening of the locking mechanism.
  • the automatic opening of the locking mechanism usually corresponds to the fact that the rotary latch is acted upon by means of a spring in the direction of its open position.
  • the catch moves immediately in its open position and releases a previously captured by her lock pin, so that an associated vehicle door can be opened.
  • the at least one additional pawl is provided according to the invention. This usually falls into the catch or the locking mechanism when the pawl is lifted from the catch. But it is also possible that the question pawl in question has previously fallen into the catch or the locking mechanism.
  • the position "locked" the locking unit ultimately so not realized with the help of separate levers or a complex mechanism, but in the core and only by the additional pawl, which enters into a certain interplay with the pawl.
  • the additional pawl ensures that even when excavated pawl, so when operating, for example, an external operating lever, the catch does not (spring assisted) assumes its open position. This is the usual locking function. As well, it is conceivable to let the additional pawl then fall into the catch when the locking should be opened by means of an internal operating lever. As a result, an anti-theft function can be additionally implemented. In other words, all common locking functions and anti-theft functions can be defined by the interaction between the auxiliary pawl and the pawl with the self-opening rotary latch. It has proven useful if the additional pawl is designed as a closing pawl.
  • the overall design is such that the additional pawl holds the catch of the locking mechanism as long as the locking unit is in its "locked” position.
  • the command "locked” for the locking unit as a control command in a mandatory control unit and according to the invention now implemented so that the auxiliary pawl (motor) is held in contact with the rotary latch.
  • the overstroke position corresponds - as is common practice - to a position of the rotary latch, which lies beyond its main closed position or main latching position.
  • the rotary latch During a closing operation of the rotary latch, it is pivoted so that the pawl initially falls into its pre-rest. This process is usually carried out by an operator who closes the associated motor vehicle door so that the locking bolt transfers the locking mechanism into its pre-locking division. Through this process, the closing device is set in motion.
  • the closing device now uses the closing catch applied to the catch to ensure that the locking mechanism or the catch from the pre-closing position or Vorrastsannon is transferred to the main closed position or main latching position.
  • the closing device works even further, in that the rotary catch or the locking mechanism is brought into its so-called overstroke division. In this overstroke position, the locking pawl can easily be lifted off the catch and put on it, without any fear of any functional impairment. In this overstroke position, the catch or the locking mechanism is now fixed by means of the additional pawl or the closing pawl.
  • the additional pawl interacts with an additional pawl contour and the pawl interacts with a pawl contour on the rotary latch.
  • the additional pawl contour and the pawl contour on the catch are designed separately from each other. This means that the additional latch contour and pawl contour are functionally and spatially separated. As a result, malfunctions can not occur and it is prevented, for example, that the pawl engages in the additional latch contour or the additional latch into the pawl contour.
  • the additional pawl usually has a motor drive, which ensures that it is applied to the catch and lifted from this.
  • the motor drive may provide for the already mentioned closing function, provided that the additional pawl is designed as a closing pawl according to an advantageous embodiment.
  • the locking unit is designed as an anti-theft unit.
  • the additional pawl ensures that the catch in the "Anti-theft on” function position is neither opened nor can it be opened when the inside operation is still applied to the outside control.
  • a locking unit in the "lock on” position usually (only) ensures that when the outside is actuated, the locking mechanism does not change into the open position, whereas, if the internal operation is acted upon, this may cause the locking mechanism to open.
  • the motor drive of the additional pawl acts advantageously both for displaying the closing function and the anti-theft function or locking function.
  • the drive of the additional pawl after completion of the closing function generally defines the function "locked” or “theft-proofed" of the locking unit or the theft deterrent unit. This is usually realized with the help of the control unit, which differentiates the closing function and the locking function respectively theft, security function from each other by software technology.
  • a motor vehicle door lock which is characterized by a mechanically particularly low effort in reliable operation.
  • the locking functions or the anti-theft functions it is not necessary to resort to a complex lever mechanism or complementary engines. Rather, these functions are represented by means of a usually existing Zuzieh Rhein anyway.
  • the Zuziehklinke obligatory in a Zuzieh becomes increasingly stable.
  • the closing device or the closing pawl or additional pawl is additionally capable of being able to define the locking functions or even anti-theft functions.
  • the additional pawl or closing pawl is left in the position "lock on” or “theft protection on” in its position in contact with the rotary latch (and after the closing process) in contrast to the prior art. Because this generally provides that the closing pawl is lifted after completion of the closing function of the rotary latch.
  • the closing pawl is fixed as an additional pawl in contact with the rotary latch, advantageously in overstroke division of the rotary latch.
  • the catch can not be automatically transferred to its "open" position, at least not as long as the closing pawl or additional pawl ensures that the catch is fixed in the overstroke division according to an advantageous embodiment. Only when the additional pawl or Zuziehklinke is lifted from the catch by a corresponding unlocking command, this is able to pivot, for example, in the main position with collapsed pawl spring assisted, so that then can be taken with lifted pawl for opening the locking mechanism.

  • the control unit 6 now ensures that the additional pawl or closing pawl 3 remains in contact with the catch 1 or invades the additional pawl contour 11 unchanged and retains this position. As a result, the catch 1 can not be opened, and not even when the pawl 2 is lifted from the catch 1. In this way, different locking functions can be defined, for example "lock on” or "anti-theft lock on”. Because each actuation of an external actuating lever and / or also internal actuating lever leads to the fact that the pawl 2 is lifted from the rotary latch 1. However, this procedure remains ineffective because the catch 1 remains unchanged with the help of the additional pawl or Zuziehklinke 3 Kochhub ein Ü. Of course, instead of the overstroke position Ü the catch 1 can also be fixed in any other position. It is also conceivable, for example, a fixation in the main position.
