A motor vehicle door lock includes a rotary latch which in a locking position encompasses a locking element that is pre-tensioned in a direction of an open position releasing the locking element. A pawl is in engagement with the rotary latch such that the latch is inhibited from moving towards the open position. A coupling section of the pawl is coupled to a drive element which moves the pawl between an engagement position and a release position, the release position allowing the rotary latch to move toward the open position. A force is applied to the pawl only in the engagement position thereof and the force application holds the pawl in engagement with the rotary latch.

A motor vehicle door latch includes a rotary latch which encompasses a closing element when in the closed position, and is preloaded toward an open position of the closing element. A safety catch is engaged with the rotary latch so that the rotary latch is prevented from moving toward the open position. A coupling section of the safety catch is dynamically coupled with a drive element and moves the safety catch between the engagement position and a releasing position so that the rotary latch can move toward the open position. The opening sound is reduced to a minimum. The drive element moves the safety catch from the engagement position toward the releasing position so that the rotary latch, which is still engaged with the safety catch during such movement, moves toward the open position.

According to the invention, when the door is locked, a locking part () is displaced into a rotary latch (), which is first pivoted from its open position into a preliminary detent position. The rotary latch () is spring-loaded () in the direction of its open position and is usually supported on a catch () by means of an initial detent section (). The rotary latch () is then rotated further by means of a motor-driven closing aid with the aid of a drive mechanism () and an eccentric element (), until it reaches a primary detent position, in which the catch () rests on a primary detent section of the rotary latch (). To obtain a reliable lock that can be universally used, a toggle-joint lever pair () and a spring-loaded follower () are provided between the eccentric element () and the rotary latch (). One fixed end () of said toggle-joint lever pair () is rotatably mounted in a locally fixed bearing () and the other free end () is forcibly guided by guide elements () and simultaneously supports the spring-loaded follower (). The toggle-joint lever pair () is supported on a control curve () of the eccentric element (). The closing displacement is attained by the extension and/or bending of the toggle-joint lever pair. The follower then seizes the rotary latch () and propels it in a motor driven manner from its preliminary detent position into its primary detent position.
