The occupant restraint system comprises one or more multistage restraining devices with pertaining triggering units, with the triggering unit pertaining to a higher stage of each multistage restraining device arranged in the corresponding ring or stub line closer to the central control unit than the triggering unit pertaining to a lower stage.
