Abstract: Regarding a vehicle equipped with an occupant restraining apparatus having a bag whose internal gas pressure is adjustable in accordance with a type of collision of the vehicle, when the vehicle is involved in a frontal collision of a predetermined magnitude or greater, an inflator 40 is activated to inflate a seat bag 20 and a lap bag 34. At the time of the frontal collision, a valve element 63 of a gas-leaking valve 60 moves forward so that the gas-leaking valve 60 becomes in a closed state. Therefore, gas from the inflator 40 does not leak through a hole 55 and can be supplied to the bags 20 and 34 while high pressure is maintained. This allows the bags 20 and 34 to be inflated immediately so that the internal gas pressure of the bags 20 and 34 is increased. When the vehicle is involved in a side collision, the valve element 63 of the gas-leaking valve 50 receives absolutely or substantially no force in the forward direction.

Abstract: An occupant protection device is provided which protects an occupant by inflating a seat bag and a lap bag. When a vehicle collision is detected, gas generators are activated and discharge gas. The gas from one of the gas generators inflates a tube. As a result, a front portion of a cushion pad of a seat cushion is pushed upward or hardened and the hips of the occupant are prevented from moving forward. A lap bag also inflates and restrains the hips of the occupant. In one form, a lap anchor inflates so that pretension is applied to a lap portion and the hips of the occupant are pushed downward. Therefore, the thighs and hips of the occupant are pushed between the lap portion and the front portion of the cushion pad which is pushed upward or hardened and are strongly restrained in the seat.

Abstract: A seatbelt webbing includes a shoulder part and a lap part. The shoulder part is a standard belt and at least part of the lap belt is an airbelt. In a front collision, a pretensioner of the shoulder part is activated, thereby retracting a specified length of the seatbelt webbing and tightening the shoulder part. As a result, part of the lap part slides through a hole of a seatbelt tongue toward the shoulder part, thereby correspondingly tightening the lap part. After a lapse of a predetermined period of time, an ignition control unit activates an inflator for the airbelt. Thus, the lap part is pulled and tightened by the inflation of the airbelt. Further, the inflation of the airbelt pulls part of the shoulder part through the hole of the tongue toward the lap part, thereby further tightening the shoulder part.

Abstract: An airbelt and an airbelt apparatus is prevented from undergoing re-elongation due to a tensile force applied to the airbelt, which is reduced in length in the longitudinal direction after expansion. An airbelt includes a first standard belt, a second standard belt, and an expandable portion therebetween. A re-elongation preventing member may include end members arranged respectively on both end sides of the expandable portion, and a joint member for joining the end members. When an inflator is activated, the expandable portion is expanded, and the length of the expandable portion is reduced, and hence the expandable portion is accommodated between the end members of the re-elongation preventing member as a whole. The expanded expandable portion is too thick to pass through belt insertion ports. Even when a significant tensile force is applied via the standard belt, the expandable portion is not elongated.
