<p><P>PROBLEM TO BE SOLVED: To provide a seat belt device for a vehicle capable of controlling a first pretensioner with high accuracy, even when dispersion occurs in a brake pedal stroke and a stroke sensor. <P>SOLUTION: This device is provided with the brake pedal stroke sensor 20 for detecting a brake operation of the vehicle and a first controller 30 for controlling tension at a webbing winding time by the first pretensioner when the generation of sudden braking is determined based on detected data of the brake pedal stroke sensor 20. The first controller 30 is provided with a means for correcting a zero point position of the brake pedal stroke when it is determined that the brake operation is not performed by the brake pedal stroke sensor 20. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
