Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism of the catch and pawl, wherein the pawl rests in the closed state of the locking mechanism with its locking contour on a latching contour of the rotary latch.
  • the locking mechanism of a motor vehicle door closure is a core component of the closure, because ultimately the locking mechanism ensures that an associated motor vehicle door is locked and held in relation to the motor vehicle body.
  • the catch of rotary latch and pawl is solid and usually made of steel to accommodate occurring at this point considerable forces can.
  • a motor vehicle door lock with the locking mechanism therein is mounted inside a motor vehicle side door and typically interacts with a locking bolt on the vehicle body, such as a B-pillar.
  • DE 42 19 429 C1 teaches a closure with an actuatable by a locking pin catch.
  • the catch can be locked in a pre-rest and in a main position by means of a pawl.
  • the pawl has not only a locking member, but also a safety locking member.
  • the catch and the pawl are massively designed for the reasons already described above, it comes when lifting the pawl of the catch often undesirable and annoying perceived "click" noises. These are often supported and reinforced by the fact that the tailgate closes a Heckraumvolumen, which acts insofar as resonant volume or can act.
  • the invention aims to provide a total remedy.
  • a generic motor vehicle door lock in the invention is characterized in that the locking contour is formed in two parts with retaining contour and rolling contour, the retaining contour interacts predominantly in the closed state of the locking mechanism with the locking contour, whereas the rolling contour beyond Opening operation of the rotary latch on the locking contour and optionally additionally rolls on a leg of the rotary latch, so that the opening rotary latch lifts virtually noiselessly from the rolling edge of the pawl.
  • the pawl is thus equipped with a special locking contour.
  • the locking contour is composed essentially of the retaining contour and the rolling contour, which are designed differently from each other.
  • the holding contour in the closed state of the locking mechanism ensures that the pawl does its original function by the holding contour interacts with the locking contour of the rotary latch.
  • the catch contour of the catch can have a total of a preliminary catch and a main catch or be formed as a pre-locking or main catch contour, wherein the catch is supported in the associated locking positions respectively on the holding contour of the pawl.
  • the pawl according to the invention still has a rolling contour, wherein the holding contour and the rolling contour as a whole define the locking contour.
  • the rolling contour generally has no supporting or locking effect. Rather, the rolling contour of the pawl only comes into action when the catch has already started its opening process, ie has left the closed position or the closed state. In this case, the holding contour are on the pawl and the locking contour on the catch not or mostly no longer engaged.
  • the rolling contour now ensures in this opening operation of the rotary latch - depending on the closed state of the locking mechanism - that the locking contour and possibly also a leg of the rotary latch can roll on the rolling contour.
  • there is a mechanical contact of the rotary catch with the pawl which exceeds the actual closed position and the associated supporting effect of the retaining contour with respect to the latching contour.
  • the rolling contour on the pawl and, on the other hand, the rollover of the locking contour or the additional leg on the catch are responsible.
  • the retaining contour and the rolling contour generally adjoin one another at the end of the locking latch on the side of the rotary latch. It is usually the procedure that the holding contour is connected to the rolling contour in Aushebecardi the pawl.
  • the lifting direction of the pawl usually corresponds to a pivoting movement about an associated axis of rotation. This pivoting movement of the pawl can be initiated mechanically and manually with a lever.
  • the pawl is usually associated with a drive unit for its motorized lifting, that is, the drive unit ensures that the pawl is lifted and also specifies the lifting direction of the pawl.
  • the pawl performs a total of the already mentioned pivotal movement about the axis of rotation. Opposite the axis of rotation or the rotation axis side end of the pawl is the rotary latch side end of the pawl with the there provided retaining contour and the rolling contour.
  • the design is usually made so that the rolling contour in Aushebeutter the pawl, the retaining contour at least partially surmounted radially.
  • the rolling contour projects beyond the retaining contour in the respective lifting direction of the pawl generally progressively or progressively radially. That is, with increasing pivot angle of the pawl about its axis of rotation and the radial distance between the holding contour and the rolling contour is larger, increases progressively.
  • the invention takes into account the fact that the opening catch and the pivoted pawl in the lifting direction increasingly remove from each other at their contact area.
  • the invention now provides at this point a compensation in that the rolling contour projects beyond the retaining contour progressively radially.
  • the design is such that the rolling contour in Aushebecardi the pawl with the catch in its closed state overlaps at least partially. Most of the rolling contour overlaps in the respective Ausheberaum with the locking contour on the catch and possibly the leg of the catch in its closed state. This overlap takes into account the fact that, when the catch is opened, the pawl and the catch generally move away from each other. In order to ensure at this point according to the invention a beyond the closed state mechanical contact can, the pawl of the catch rushes as it were.
  • the rolling contour and the holding contour are each typically designed as circular arcs. It works regularly with different radii and / or different centers for on the one hand the rolling contour and on the other hand, the holding contour. In general, the radius of the rolling contour exceeds that of the holding contour, so that the rolling contour can correspond to the already described function of the "caster" with respect to the opening movement of the rotary latch.
  • the center of the rolling contour and the center of the retaining contour are usually spaced apart. It is generally provided that the center of the retaining contour is arranged below the axis of rotation of the pawl and the center of the rolling contour above the axis of rotation. In addition, the respective center points and the axis of rotation are preferably located on a common connection path.
  • a motor vehicle door lock is provided with a locking ratchet pawl and rotary latch, which can be opened particularly particularly quiet.
  • the low noise is achieved in that the pawl and the rotary latch - starting from the closed state of the locking mechanism - have a more extensive mechanical contact.
  • This mechanical contact is made on the one hand by the rolling contour of the pawl and on the other hand, the locking contour of the catch and possibly also a leg of the catch.
  • the design is such that the adjacent contours of a

  • a latching contour 13 is still provided on the rotary latch 2, which, however, is unimportant for the following considerations.

  • the retaining contour 11 and the rolling contour 12 are first arranged once at a rotary latch end of the pawl 3 and close to each other.
  • This rotary latch-side end of the pawl 3 is the axis of rotation-side end of the pawl 3 opposite, on which the axis of rotation 5 of the pawl 3 is found.
