1. A method for producing a detent pawl having a latching portion configured to engage in a locking toothing, a bearing portion configured to rotatably mount the detent pawl about an axis of rotation, and having a locking portion configured to contact a locking catch which is movable along the detent pawl, comprising the following steps:
providing a detent pawl blank;
providing a forming tool with a forming contour, wherein the forming contour has a load portion and a guide portion;
forming the detent pawl blank by the forming tool in a forming direction, wherein a depression configured to receive the locking catch is produced on the locking portion, wherein the load portion defines a load region of the depression configured to support the locking catch in a locking position, and wherein the guide portion defines a guide region of the depression configured to guide the locking catch during an actuating movement, wherein the locking portion has a lifting surface and a free floating surface, wherein the lifting surface and the free floating surface are connected to each other via a locking radius, wherein the load region is introduced by the load portion at a location of the locking radius, and wherein the guide region is introduced into the lifting surface by the guide portion.
