Definitions

  • the invention relates to a lock for a motor vehicle, comprising a catch of a catch and at least one pawl, wherein the catch is fixed by the pawl in a detent position, a means for braking at least one opening movement of the catch and a lock holder cooperating with the locking mechanism.
  • the noise behavior plays a major role, since the operator of the motor vehicle with the noise behavior is a quality feature is taught.
  • a lock holder which is usually fastened to the motor vehicle, encounters a locking mechanism comprising a catch and at least one pawl, wherein the lock catch strikes the catch arm of the catch.
  • the rotary latch may, for example, have a plastic casing with or without a buffer element in order to reduce the closing noise.
  • a friction brake acting on the fork bolt is provided.
  • This friction brake has a leaf spring, which is fastened with one end in a clamping sleeve and with another end directly on the lock housing. The leaf spring is convexly curved towards the fork catch.
  • a locking mechanism for a motor vehicle lock which has a locking mechanism which can be opened quietly. If the locking mechanism is in a main locking position, then a brake pad adjoins the rotary latch such that a rotational movement of the rotary latch in the direction of the open position can be initially braked. After a release of the pawl of the rotary latch pivots Rotary latch in its opening direction. Such pivoting is initially slowed down by the brake pad. Initially, the friction effect between the rotary latch and the brake pad increases until, finally, if the friction effect is too great, the brake pad is moved out of its guide.
  • the object of the invention is to provide a locking mechanism for a motor vehicle lock, which improves the noise behavior and in particular the noise behavior during the opening of the locking mechanism. Moreover, it is an object of the invention, only to take influence on the opening sound of the locking mechanism of the motor vehicle lock when the lock holder has come into engagement with the locking mechanism. In addition, it is an object of the invention to provide a structurally simple and inexpensive locking mechanism, with the influence on the opening noise is acceptable.

If the braking means in the inactive starting position, so the catch and / or the pawl can move independently of the braking means. In other words, the locking parts can be moved without the braking means exerting an effect on the locking parts. In this initial position, the braking means is inactive and does not interact with the locking parts. Only by the transfer of the braking means in the engaged position or the active position, the brake means engages with at least one locking part in engagement.
  • a further advantage results when the brake means has at least one brake block, wherein the brake block in the engaged position can be brought into engagement with at least one locking part. Due to the formation of elevations on the braking means braking forces are targeted in the locking parts and preferably the catch introduced.
  • the brake blocks or the brake block can be designed in this way and on the Be arranged braking means that the braking means acts specifically only on portions of the locking parts.
  • the design of the rotary latch can be utilized advantageously in order to be able to introduce braking forces into the rotary latch, for example over a large radius range of the rotary latch.
  • brake pad two, three or more brake blocks can be formed on the brake means.
  • Braking means in the form of brake blocks can complement each other and / or be designed as punctual elevations on the brake means.
  • At least one locking part can have at least one brake block.
  • at least one brake block By forming at least one brake block on a locking part, it is possible to exploit the interaction between the locking part and the brake means in order to initiate a targeted braking action in the locking part.
  • the at least one brake block of the brake means cooperates with at least one brake block of a locking part, in particular of the rotary latch. Due to the interaction of the brake blocks on the brake means and the locking part, a targeted and punctual braking action on the locking part, in particular the rotary latch, can be achieved.
  • brake blocks can engage in such a way that a punctual force is required to overcome the brake blocks, by means of which the brake catch can be braked, in particular at the time of opening. For example, if two pairs of brake blocks are formed on the locking mechanism and the braking means, then the two brake block pairs engage in one another in the main locking position.
  • a braking effect at the time of opening can be provided in a very targeted and defined manner.
  • brake blocks in the form of trapezoids can abut each other or intermesh with the oblique sides of the trapezoids.
  • the engagement conditions between moving locking part and brake means is adjustable. Only in the active position, that is, the engagement position, the brake block of the brake means can be brought into engagement with the brake block on the locking part and preferably the catch.
  • the braking means thus acts only in the main detent position.
  • the braking means must be moved to the active position, wherein the braking means in the active position spring biased against the lock holder.
  • the rotary latch must overcome the resistance of the braking means, wherein targeted at the time of release of the pawl of the rotary latch, the maximum resistance by the interlocking brake blocks is present.
