Definitions

  • the invention relates to a motor vehicle lock with noise optimized Locking elements such as lock latch and pawl with the features of Preamble of claim 1.
  • Motor vehicle locks of the type in question are locks for side doors, Rear doors and tailgates, but otherwise also for other closure elements in motor vehicle bodies.
  • the motor vehicle locks a safety very relevant component.
  • the closing elements as a rule, as Rotary latch executed latch and one holding this in the main closed position Pawl, the crucial components.
  • the crucial components For the sake of safe Recording the occurring tearing forces are latch and pawl regularly made of high-strength steel.
  • a motor vehicle lock has for a side door of a motor vehicle body a main closing position, this upstream but also one Preliminary position, in which the vehicle door is not completely closed is, but already provisionally arrested. This serves additional Safety.
  • the main closing position is by the engagement of the latch realized the pawl on the main catch of the latch, the prelocking is achieved when the detent of the pawl in the pre-rest the latch falls.
  • the essential core of the teaching of the invention is the contacting of lock latch and pawl outside the immediate contact on main load and pre-rest no longer in the intervention level, but in one parallel buffer layer to take place. Without constructive Restrictions resulting from plastic-injection technical necessities one is free here, for all possible relative positions of lock catch and Pawl always a strong sound-absorbing contact surface plastic / plastic provide. Regardless, it is possible at the intervention level the metal / metal engagement with the main catch and pre-rest unchanged sure. With the escape into the buffer plane parallel to the engagement plane, in the only plastic material of latch and pawl the necessary contours are created, one creates oneself an additional one Degree of freedom, which helps to reduce the noise during Opening and closing of the motor vehicle lock according to the invention systematically can be used.
  • Dodge the plastic material into an additional buffer layer parallel to the plane of engagement of latch and pawl also has the additional effect with the consequence that additional elements such as switch control cams, Magnet inserts or the like can be arranged and integrated.
  • Fig. 1 shows the basic principle of a known from the prior art Motor vehicle lock with a particular designed as a rotary latch Lock catch 1 with a main catch 2 and here and preferably a pre-rest 3 and with a pawl 4 with one with the latch 1 in the main branch. 2 and in the pre-rest 3 engaging detent 5.
  • the latch 1 is by means of a bearing bush 6 on the rear plate of the motor vehicle lock, the not shown here, stored, as is the pawl 4 by means of a Bearing bush 7 stored. It is here as claimed on train pawl. 4 executed.
  • the main catch 2 and 3 Vorrast with the Latch 5 of the pawl 4 lie in a plane and move, the Engagement plane 8.
  • At least the inter-engaging sections the latch 1 and the pawl 4, so the main catch 2, the pre-rest 3 and the top of the latch 5, are made of metal, as already explained above to be able to ensure the necessary locking forces.
  • Fig. 3 makes it clear that by the design of the plastic material 9; 10 of latch 1 and pawl 4 in the buffer level 13 always a minimal Gap s between metal existing areas of latch 1 and Pawl 2 is guaranteed.
