Abstract (en)
[origin: CA2903271A1] In order to minimize the sliding friction between the locking parts (30, 31) that is, between the pawl (5) and the rotary latch (2) of a motor vehicle lock (1), it is advantageous if, during the production process, the different latch surfaces (12, 13) of both locking parts (30, 31) are provided with a stamping contour (14) having straight grooves (17) and with a stamping contour (11) characterized in that the provided grooves (18', 19') are oblique. Said oblique grooves (18', 19') of the latch surface (13) on the pawl (5) are placed in the position indicated in figure (3) such that the entire pawl is twisted (5) about the longitudinal axis (38) thereof. Also, at least two overlapping points are provided between the straight grooves (17) and the oblique grooves (18', 19') such that both of the locking parts (30, 31) come into mutual contact reducing the friction.
