Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, further comprising an actuating lever mechanism with at least one actuating lever and a clutch lever, and with at least one blocking element, which in normal operation, a mechanical connection between the actuating lever and the clutch lever and acceleration forces of predetermined size, for example in accident mode , a mechanical separation between the operating lever and the clutch lever - indirectly or directly - causes.
  • Centrifugal or mass barriers or crash barriers are known to prevent inadvertent opening of a door, a flap or a lid in a motor vehicle.
  • the occupants located in the interior of the body are optimally protected in the event of an accident and, for example, safety devices such as airbags, stiffeners, etc., which are located in a motor vehicle side door, can optimally unfold their effect.
  • safety devices such as airbags, stiffeners, etc.
  • Such centrifugal or mass barriers or crash barriers are known in various configurations.
  • a connecting element is realized, with the aid of which the pawl is connected as part of the locking mechanism with at least one handle unit.
  • the connecting element is equipped with at least one connecting lever. By pulling the handle, the lever is actuated and engages a contour of the pawl. This allows the locking mechanism to be opened.
  • a motor vehicle door lock with a locking mechanism, an actuating lever mechanism with at least one Operating lever and a clutch lever, and with at least one blocking element, which causes a mechanical connection between the actuating lever and the clutch lever in normal operation and when occurring acceleration forces exceeding a predetermined size, for example in an accident, a mechanical separation between the actuating lever and the clutch lever causes.
  • a blocking element in the form of a functional element is realized, which is connected to at least one spring-elastic component.
  • the spring-elastic component extended.
  • the functional element in question is displaced as a result of the change in length of the resilient member in a position which blocks or disengages the movement of the pawl. In this way, forces in three-dimensional space should be able to be mastered and easy positioning possible.
  • the invention is based on the technical problem of developing such a motor vehicle door lock so that the noise is reduced during operation and in particular bouncing noises are avoided. In addition, the reliability is to be increased.
  • the invention proposes in a generic motor vehicle door lock that in addition to the blocking element is provided a blocking element which acts on an actuator for the clutch lever so that at least in the accident mode, the clutch lever is not only mechanically separated from the operating lever, but additionally his Position "locked" occupies.
  • the blocking element which causes a mechanical connection between the operating lever and the clutch lever in normal operation and a mechanical separation of the two levers from each other during accident operation.
  • the clutch lever in accident mode according to the invention yet another blocking element, or in addition to the blocking element already mentioned locking element is realized. This blocking element works on a control element for the clutch lever.
  • actuator and clutch lever can form a structural unit.
  • the actuator and the clutch lever are designed spatially and structurally separate from each other.
  • the interaction of the shape that at least in accident mode or occurring acceleration forces predetermined size of the clutch lever is not only mechanically separated from the operating lever, namely by the blocking element.
  • the locking element in conjunction with the adjusting element for the clutch lever additionally ensures that the clutch lever assumes its position "locked”, at least in accident mode. That is, the locked position of the clutch lever can also be taken or maintained beyond the accident operation. So as soon as the actuator is acted upon by the occurring acceleration forces of predetermined size sufficiently that with the help of the blocking element, the actuator for the clutch lever undergoes significant loading, the actuator ensures that the clutch lever from its previously typically assumed position "unlocked” in the Position "locked” is pivoted.
  • the structure of the motor vehicle door lock according to the invention is simple and functional. Because the blocking element ensures in normal operation that a mechanical connection between the operating lever and the clutch lever is present or is effected. Due to the mechanical connection between the actuating lever and the clutch lever in normal operation, an actuation of the actuating lever causes the blocking element to be moved as well.
  • the blocking element is regularly a disk that can rotate about an axis.
  • the blocking element usually has a spring, by means of which the blocking element is coupled to the actuating lever. The spring in question is interposed for this purpose between the blocking element and the actuating lever.
  • the spring is advantageously a leg spring.
  • This leg spring regularly has a free leg, with which it rests on the blocking lever.
  • the blocking element provided in addition to the blocking element is usually an inert mass or a weight.
  • the blocking element is rotatably mounted on the actuating lever.
  • the locking element may be interposed between the locking element and the operating lever, a spring.
  • the blocking element works on an actuating element for the clutch lever.
  • the actuator in turn is designed as a spring element.
  • the spring element is typically a leg spring.
  • the actuator is arranged regularly on the operating lever.
  • the blocking element generally has a setting contour for the adjusting element or spring element or the leg spring.
  • the control contour works on a free leg of the leg spring.
  • the clutch lever experiences no action and typically retains its "unlocked” position.
  • the locking element is pivoted relative to the actuating lever, for example during accident operation, and thereby comes the adjusting contour out of engagement with the free leg of the leg spring or the control element, this free leg can pivot the clutch lever, and in most cases “unlocked” from its previously assumed position the position "locked”.
  • the accident operation or the acceleration forces of predetermined size usually lead on the one hand to the fact that the blocking element holds the operating lever. Because the operating lever is not able to move the inertial mass of the blocking element on the intermediate spring in this context. Rather, the blocking element remains mostly at rest, so that in this process at best, the intermediate spring (slightly) is elastically deformed.
  • the operating lever Since the operating lever is held in the accident by the blocking element as it were or is largely retained, the operating lever can not work on the (in unlocking position) clutch lever such that the operating lever mechanism acts as the normal operation, the locking mechanism for opening. Rather, a mechanical separation between the operating lever and the clutch lever is effected during accident operation and the locking mechanism can not be opened.
  • the occurring acceleration forces of predetermined size ensure that, on the other hand, the blocking element is opposite the actuating lever is pivoted.
  • the blocking element is rotatably mounted on the actuating lever, in consideration of the intermediate between the locking element and the actuating lever spring.
  • the inertial forces acting on the blocking element now also ensure that the blocking element is pivoted away from the actuating lever, which as it were defined with the aid of the blocking element.
  • the interposed between the locking element and the operating lever spring is tensioned.
  • the clutch lever is still “locked” in its position. Only when the blocking element is actively moved towards the actuating lever and the adjusting contour returns the free leg, the clutch lever can be reset from its "locked” position to the "unlocked” position. That is, the leg spring or locking spring can be reset by pressing the lock in the opposite direction back to its original position. Following this, the motor vehicle door lock according to the invention is again in its basic position.
  • the scenario described for the accident operation is not necessarily coupled to acceleration forces, which at a such a crash, typically more than 4 g. But in principle, the described operation is also given when the acceleration forces are exerted by an operator in a quick pulling, for example, the door handle. That depends on the particular design.
  • the acceleration forces in question typically operate in the vehicle Y direction, ie in the transverse direction, in contrast to the longitudinal direction of the motor vehicle, which is regularly identified with the X direction. In contrast, the Z direction denotes the vertical axis direction.
  • a motor vehicle door lock is made available in which, in particular, a vibration behavior occurring due to bouncing has no influence on the opening process. Because the lock is automatically transferred to its position "locked” in an acceleration in the mentioned Y-direction of predetermined size. Because from a certain threshold for the acceleration forces in question, the blocking element undergoes the described pivoting with respect to the actuating lever, so that the control contour on the blocking element releases the control element respectively realized at this point spring or leg spring or locking spring. The released locking spring is then in turn able to transfer the clutch lever from its previously assumed position "unlocked” in the "locked” position.
  • a motor vehicle door lock which has a not shown locking mechanism of the catch and pawl.
  • On the ratchet operates an operating lever mechanism 1, 2, which is equipped in the embodiment with at least one operating lever 1 and in addition a clutch lever 2.
  • the operating lever 1 is not limited to an external operating lever 1.
  • the blocking element 3 has an associated spring 5, which is designed as a leg spring 5.
  • leg spring 5 enclose a central pin 6 of the disk or of the blocking element 3.
  • the leg spring or spring 5 has a leg 5a connected to the disk 3 and a free leg 5b.
  • a supplementary blocking element 9 develops an effect.
  • this locking element 9 is in the core to an inertial mass, which is connected via a bolt 10 rotatably connected to the actuating lever or external actuating lever 1.
  • the locking element 9 can perform a clockwise movement relative to the external actuating lever 1, as can be seen in the transition from the Fig. 3 to Fig. 4 recognizes.
  • the rotatably mounted on the actuating lever 1 locking element 9 is equipped with a control contour 12.
  • the spring 11 ensures that in normal operation, the locking element 9 rests with its stop 13 on the stop pin 14 and only in accident mode in the Fig. 4 shown clockwise rotational movements of the locking element 9 against the force of the spring 11 are possible and allowed.
  • the blocking element 9 operates on an actuating element 15 for the clutch lever 2.
  • the actuating element 15 for the clutch lever 2 in the exemplary embodiment is a spring element 15 which is present is equipped as a leg spring 15.
  • the leg spring 15 has a free spring leg 15a, which rests on the clutch lever 2, as soon as the setting contour 12 on the locking element 9, the actuator 15 and the leg spring 15 is not (more) applied, as the Fig. 4 represents.
  • the leg spring 15 is connected to the stop pin 14.
  • the locking element 9 is in contact with the actuating lever 1, for which the spring 11 provides.
  • the adjusting contour 12 on the locking element 9 ensures that the free spring leg 15a of the leg spring 15 and the adjusting element 15 for the clutch lever 2 is not applied to the clutch lever 2.
  • the pivoting movement of the actuating lever 1 counterclockwise about its axis 7 ensures that the blocking element 3 in the Fig. 2 indicated clockwise movement performs. Because the operating lever 1 takes over its boom 1a the free spring leg 5b of the spring 5 on the blocking element 3 with. The spring 5 is not compressed in this case, but experiences the blocking element 3, the previously described pivotal movement in a clockwise direction about its axis. 4
  • the acceleration forces F of predetermined size provide evidence of Fig. 4 in the scenario accident operation for the fact that the locking element 9 is pivoted relative to the connecting bolt 10 respectively due to its rotatable mounting on the actuating lever 1.
  • the interplay between the stop 13 on the locking lever 9 and the stop pin 14 in conjunction with the spring 11 allow only a pivoting movement of the locking element 9 with respect to the hinge pin 10 and the axis of rotation formed thereby only 10 in a clockwise direction. This can be seen in the transition from the Fig. 3 to Fig. 4 ,
  • the vehicle door lock is in the "locked” position.
  • any vibrations of the operating lever mechanism 1, 2 and the operating lever 1 are not transmitted to the locking mechanism, because such oscillating movements of the operating lever mechanism 1 with respect to the clutch lever 2 in the "locked” position go empty.
  • the clutch lever 2 "unlocked” in its position according to the Fig. 1 to 3 be transferred.
  • the motor vehicle door lock according to the invention is again in principle in its starting position Fig. 2 ,
