VEHICLE PASSENGER PROTECTION DEVICE

摘要

Under the condition that a seat belt (6) winding operation by a winding device (7) is deactivated while the operation of a brake (1) by an automatic brake device is activated, the seat belt (6) winding operation by the winding device (7) is carried out when the degree of deceleration of the vehicle based on the operation of the brake (1) by the automatic brake device is a large value of not less than a threshold value. This avoids the acceleration of the seat belt (6) in a pulling direction becoming equal to or more than a value such that the seat belt (6) is locked without the seat belt (6) being wound by the winding device (7). As a result, the locking of the seat belt (6) can be prevented, so that the discomfort that a passenger may feel due to the locking can be suppressed.
