Definitions

  • the invention relates to a motor vehicle lock for a movable part of a vehicle, in particular for a door, sliding door, flap, tailgate or hood according to the independent claim 1 and method for reducing the opening noise according to the independent method claim.
  • Locks are known from the prior art, which have a damping layer or sheath on the rotary latch, which noise should be reduced.
  • DE 102006 028 423 A1 discloses a rotary latch with such a sheath, wherein the rotary latch is formed in particular in the region of the fork-shaped inlet slot with a damping layer for noise reduction.
  • a disadvantage of the known from the prior art solutions is that only creaking noises between the catch and a striker in the closed position can be prevented. However, noises that occur when opening the blocking position and the thus released rotary latch can not be reduced.
  • the object of the present invention to at least partially improve the disadvantages known from the prior art.
  • a lock for a movable part of a vehicle in particular for a door, flap, tailgate or hood.
  • the lock has a lock housing, a lock plate and at least one rotary latch arranged movably on the lock housing and / or the lock plate, wherein the rotary latch can be brought into an open position and at least one latching position.
  • at least one of the lock housing and / or the lock plate Preferably arranged in the inlet region of a lock holder / striker, arranged buffer unit, wherein at least one brake element is arranged on the buffer unit, so that at least during movement of the catch in the open position, the brake element with the catch is at least partially brought into contact.
  • the brake element is arranged on the buffer unit such that a braking torque / a braking force can be transmitted to the rotary latch. If the catch is now released from the locked position and moves in the direction of the open position in which a lock holder, also referred to as a closing bracket, is released, the rotary latch is braked and the disturbing opening noise is at least reduced or eliminated.
  • a pawl holds the catch with a closing moment in its locked position. If the pawl is now pivoted out of the locked position, then a lateral contour region of the rotary latch slides over an adjacent lateral blocking contour region of the pawl and is finally moved over an edge of the pawl. If the lateral contour region of the rotary latch slides over this pawl edge, the rotary latch is then accelerated sharply abruptly.
  • the brake element according to the invention is provided, which acts on the rotary latch when the pawl is pivoted out and the rotary latch thus moves in the direction of the open position. The contacting thus causes a grinding or rubbing of the rotary latch on the brake element, whereby the acceleration is at least partially braked.
  • a plurality of brake elements are arranged on the buffer unit. These may be offset and / or arranged adjacent to each other and brought into contact at different positions on the rotary latch. In this way, the braking force or the braking torque can be increased.
  • the brake element is designed essentially as a convex local elevation on the buffer unit. It is conceivable that the braking element extends cylindrical, rectangular, as a curvature or pyramid-shaped out of the buffer unit out.
  • the height of the brake element corresponds at least to the constructively predetermined distance between the rotary latch and buffer unit, so that a contact can be made possible.
  • the braking element has a height of between about 1 mm and about 10 mm, preferably between about 2.5 mm and about 5 mm.
  • the buffer unit may have at least one buffer pocket.
  • the braking element may be arranged in a form-fitting and / or material and / or non-positive manner.
  • the buffer pocket is preferably designed as a material recess in the buffer unit and can thus further reduce the transmission of vibrations or brake noise.
  • the brake element can, for example, plugged, screwed or pressed.
  • the buffer bag can have a clip or snap connection, so that the brake element can be clipped or latched in the buffer bag.
  • the brake element is formed from a plastic, in particular elastomer. It is also conceivable that the brake element comprises a multi-component plastic. Plastic is inexpensive and also has good braking properties.
  • the brake element may comprise thermoplastics. The use of plastic, especially elastomer and / or thermoplastic allows an at least partially deformable design of the brake element.
  • the braking element may have, at least in sections, a Shore D hardness of between about 40 and about 80, preferably between about 50 and about 65. Moreover, it is conceivable that the braking element, at least in sections, has a Shore A hardness of less than 80, preferably less than 70 and particularly preferably less than 60.
  • the plastic has a high coefficient of friction, whereby the braking effect is increased.
  • the brake element is integrally formed, in particular of the same material with the buffer unit.
  • a cost-effective production can be made possible, wherein the design effort is low.
  • a weight-optimized design can be achieved, wherein the constructive freedom can be increased.
  • the buffer unit and the brake element may be formed as a plastic injection molded part.
  • the braking element has a braking contour, which is substantially hemispherical in shape, in particular with a radius between about 1 mm and about 5 mm, preferably between about 2 mm and about 3 mm.
  • the brake element is designed as a substantially elongated brake shoe, wherein a longitudinal surface can be brought into contact with the rotary latch.
  • a longitudinal / contact surface may moreover have a surface structure, whereby the braking properties can be improved.
  • the surface may be roughed, ribbed or smoothed, formed in the longitudinal and / or transverse direction. As a result, a noise reduction can be achieved, so that a squeaking of the catch and brake element is largely reduced.
  • the brake element is at least partially wedge-shaped.
  • the wedge-shaped surface is that surface which is arranged essentially at right angles to the rotary-trap movement direction. It is conceivable that the brake element with a latching arm of the rotary latch, in particular a longitudinal surface of the latching arm, is brought into contact. This allows a structurally simple solution, since the buffer unit is usually arranged parallel to the latching arm, in particular parallel to the longitudinal surface of the latching arm.
  • the convex brake element extends in the direction of locking arm and then contacts the longitudinal surface along the direction of movement of the locking arm with respect to the fixed, taken in vorteilafterweise in the lock housing, brake element, so that the braking force can act on the catch.
  • the locking arm can also be referred to as a tentacle.
  • a braking surface is formed on the latching arm, in particular on the longitudinal surface, wherein the braking surface is geometrically larger than the surface of the braking element which can be brought into contact with the braking surface.
  • the braking surface of the latching arm of the rotary latch is preferably formed as a contour, wherein the braking element is movable in the region of the contour and thereby brought into contact.
  • the braking surface is geometrically larger than the surface of the brake element, which can be brought into contact with the braking surface. So it can be ensured that the braking element is always arranged in the region of the braking surface during the contacting.
  • the longitudinal surface to describe in the invention the surface of the rotary latch, which is arranged in a built state parallel to the wall of the lock housing or the lock plate on which the rotary latch is rotatably mounted.
  • the braking element is at least partially elastic. Deformation of the brake element can increase the braking effect and / or increase the contact area of the brake element and the rotary latch when the brake element presses against the rotary latch.
  • a method for reducing the opening noise of a rotary latch of a motor vehicle lock according to the invention in particular door lock, sliding door lock, tailgate lock and / or hood lock of a vehicle is claimed to achieve the object.
  • a brake element exerts a braking torque on the catch at least during an opening movement of the catch, whereby the opening speed of the catch is reduced, so that opening noise can be reduced.
  • the catch is released for unlocking by the pawl.
  • the rotary latch Due to the force of the door seal, which acts on the door and presses in the direction of the open position, the rotary latch is acted upon in the open position with a force, so that the rotary latch rotates about an axis of rotation and can release a lock holder. If the pawl is pivoted out of the blocking position, then an outer contour region of the rotary latch slides over an adjacent blocking contour region of the pawl and is finally moved over an edge of the pawl. If the outer contour region of the rotary latch slides over this pawl edge, the rotary latch is then accelerated sharply abruptly.
  • the brake element according to the invention is positioned such that immediately after release of the rotary latch by the pawl, the brake element contacts the rotary latch. The braking effect now arises by a grinding or friction of the brake element on the rotary latch as a result of the engagement of the rotary latch and arranged on the buffer unit brake element.
  • Fig. 3 shows a possible embodiment of a lock according to the invention in a locking position
  • Fig. 4 shows the embodiment of Fig. 3 when leaving a braking area.
  • Fig. 1 shows a possible embodiment of a buffer unit 13 according to the invention with a brake element 13.1, wherein the brake element 13.1 is arranged in a buffer bag 13.2.
  • the buffer pocket 13.2 is formed as a material recess in the form of a slot.
  • the brake element 13.1 protrudes with one end out of the buffer pocket 13.2 of the buffer unit 13.
  • the protruding end is hemispherical in Fig. 1.
  • the hemispherical part of the brake element 13.1 can be brought into contact with a rotary latch, so that a braking force is transmitted to the rotary latch and the noise when unlocking the rotary latch can be reduced.
  • FIG. 2 shows a sectional view along a line AA of an embodiment of the buffer unit 13 from FIG. 1.
  • the brake element 13.1 is integrally formed with the buffer unit 13.
  • a hemispherical region of the brake element 13.1 extends out of the buffer unit 13, so that a contact with a rotary latch can be achieved.
  • the brake element 13.1 points at the hemispherical end preferably has a radius R between about 1 mm and about 5 mm, preferably between about 2 mm and about 3 mm.
  • Fig. 3 shows a possible embodiment of a lock 10 according to the invention with a lock housing 1 1 and a movably arranged on the lock housing rotary latch 12.
  • the rotary latch 12 is located in Fig. 1 in a locking position, in particular a main latching position.
  • the rotary latch 12 has a locking contour 14 which can be brought into operative connection with at least one pawl, not shown.
  • a buffer unit 13 is preferably arranged in a form-fitting manner on the lock housing 1 1, wherein the buffer unit 13 is arranged behind the rotary latch 12 in the view shown.
  • the buffer unit 13 extends in Fig. 3 substantially transversely to the fork-shaped inlet slot 15 of the rotary latch 12, i. the buffer unit 13 is arranged in the perspective shown, horizontally / horizontally to the position of the inlet slot 15 shown.
  • the brake element 13.1 is arranged at one end 13.3 and contacts the rotary latch 12 on a longitudinal surface in the region of the braking surface 12.3.
