Abstract:
1. A seatbelt apparatus for a vehicle, comprising: a webbing for restraining a passenger on a seat; a retractor for winding and rewinding the webbing; a first pretensioner that allows the retractor to wind the webbing thereinto or rewind the webbing therefrom; a second pretensioner that applies a tension to the webbing in an emergency for the vehicle, thereby restraining the passenger through the webbing; a deceleration detecting sensor for detecting a decelerating state of the vehicle; and a controller for controlling the operations of the first pretensioner and the second pretensioner corresponding to a detected value from the deceleration detecting sensor, wherein the controller includes a correcting unit for correcting the detected value of the deceleration detecting sensor in anticipation of a future condition so as to advance a timing of the first pretensioner to wind the webbing.
