  • the disengagement of components can also lead to noise, especially if the components are under tension during the intervention. So during a closing movement of a motor vehicle lock It locks a locking mechanism in the locking system against the pressure of a door seal, for example, whereby a pawl interacts with a rotary latch and the pawl holds the rotary latch in the locked position. If the locking mechanism is now opened, there is an abrupt releasing of the locking mechanism due to the prestressing of the seal, which on the one hand generates noise and on the other hand the locking mechanism parts are greatly accelerated.
