Abstract

Parking detent pawls are known which are suitable for securely holding a vehicle in a parked state. The aim of the invention is to provide a detent pawl for a parking lock which is characterized by a high degree of operational reliability. For this purpose, a method is proposed for producing a detent pawl with a latching section for engaging into a locking toothing, a support section for rotatably supporting the detent pawl about a rotational axis, and a locking section for resting against a locking bolt which can be moved along the detent pawl, having the following steps: providing a detent pawl blank; providing a shaping tool with a shaping contour, said shaping contour having a load section and a guide section; and shaping the detent pawl blank in a shaping direction by means of the shaping tool, wherein a depression for receiving the locking bolt is produced on the locking section, the load section defines a load region of the depression for supporting the locking bolt in a locking position, and the guide section defines a guide region of the depression for guiding the locking bolt during an actuation movement.
