<p><P>PROBLEM TO BE SOLVED: To accomplish stabilization of duty control relative to a power source voltage, including bringing a standing up time within a predetermined range when impact is previously forecasted and tension is given to a webbing. <P>SOLUTION: The standing up time at starting of rolling up of the webbing 28 can be converged to a desired range by determining the optimum duty control value in every varied power source voltage relative to variation of the power source voltage. In particular, incompatible sense is not given to an occupant at giving of tension to the webbing 28 at pre-crash action. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
