An automotive seat belt buckle pretensioner assembly includes a special mounting bracket for supporting the operating components of a pyrotechnic-powered cable extending from the seat belt buckle around a cable-redirection pulley. The mounting bracket includes a flat major wall that is parallel to a major wall on the pulley support structure, so that the pulley is located within the space defined by the parallel walls. A bolt, or rivet, extending between the parallel walls provides shaft support for the pulley, while acting as a connector mechanism between the pulley support structure and mounting bracket.
