Abstract

A locking device for a vehicle door comprising a rotary catch which can be arrested by a pawl and which serves for trapping a closing element when the vehicle door is closed. The pawl has a pawl blocking surface and the rotary catch has a counterpart catch blocking surface which can be placed in engagement with the pawl blocking surface. A special feature resides in that the pawl or the rotary catch has a tracking lever by means of which the pawl blocking surface or the counterpart catch blocking surface can be caused to perform a tracking movement. During this tracking movement, the rotary catch is pivoted over a defined pivot angle (alpha) in an opening direction without the pawl blocking surface and the counterpart catch blocking surface moving out of engagement in the process, therebyreducing the seal loads prior to release of the rotary catch.
