Patent ID: 8387424

Claim:
A method for manufacturing a rotary bolt for a locking system of a motor vehicle comprising at least a first portion and a second portion that are complementary, capable of being assembled in at least one overlap zone in order to form a stator inside which a rotor is capable of rotating, the method comprising: assembling said first and second portions in order to position at least one orifice in the overlap zone, wherein the at least one orifice is formed in the first portion of the stator facing an opening of a corresponding cavity formed in the second portion of the stator; and crimping by inserting a crimping punch into each orifice in order to at least partially deform a wall of the orifice in a direction of the corresponding cavity so as to crimp the assembly of the first and second portions of the stator, wherein the crimping punch comprises one selected from the group consisting of a rounded-shaped deformation end in order to continuously deform a portion of the wall in the cavity during crimping and a substantially flat-shaped deformation end in order to discontinuously deform the portion of the wall in the cavity during crimping.
