Abstract

A seatbelt retractor device includes a pre-tensioner section (78), and a force limiter section (76) that can change a magnitude of a load at which to start reducing tension of the retracted seatbelt. A seatbelt control ECU (24) activates the pre-tensioner section (78) when a deceleration G detected by a floor sensor (14) exceeds a first threshold, and acquires a collision velocity from a radar device (18) and sets a second threshold value to a lower value the greater the collision velocity. The seatbelt control ECU (24) controls the starting load for tension reduction by the force limiter section (76) to be a high load when the deceleration G has exceeded the second threshold within a determination time period after activation of the pre-tensioner section (78), and controls the starting load for tension reduction to be a low load when the deceleration G has not exceeded the second threshold within the determination time period.
