A seat belt apparatus for a vehicle including: a belt reel; a emergency locking retractor which performs a mechanical locking of the belt reel so as not to rotate in a direction of unwinding a webbing when an unstable behavior of the vehicle is detected by a vehicle condition detection device, and then automatically release the locking if the belt reel rotates in a direction of winding the webbing greater than or equal to a predetermined amount; and a locking continuity determination device which determines whether or not the locking continues after the emergency locking retractor performs the locking based on the vehicle condition and variation of the rotational position of the belt reel, wherein a control device makes a driving motor rotate so as to release the locking if the locking continuity determination device determines the locking continues for greater than or equal to a predetermined amount of time.

Seatbelt apparatus for vehicle

The seat belt device includes a first unit, a second unit, seat belt webbing, a spindle, a first pretensioner, a second pretensioner, and a controller. The first unit determines a possible collision of an automobile in response to a manipulation of the automobile by a driver. The second unit detects the collision of the automobile. The first pretensioner has a motor to rotate in response to a signal indicative of the possible collision determined by the first unit. The second pretensioner is pyrotechnically driven to rotate in response to a signal indicative of the collision detected by the second unit. The controller is configured to cancel an operation of the first pretensioner after an activation of the second pretensioner. The first pretensioner includes a limiter for restricting the motor from transmitting a driving force to the spindle exceeding a predetermined threshold.
