In a passive seatbelt system, an occupant restraining webbing can be automatically fastened to or unfastened from an occupant in accordance with the condition of the occupant getting into or out of an automotive vehicle. When required, a webbing driving means is driven for a predetermined period of time for fastening or unfastening the webbing. Furthermore, when the webbing has moved to a webbing fastened position or unfastened position within the predetermined period of time, an electric power fed to the webbing driving means is cut off, whereby the webbing driving means can be reliably protected even if an overload acts on the webbing driving means.
