Abstract: A seat-mounted airbag device is provided with an airbag including front-and-rear chambers and an airbag main body. At a time of collision of a vehicle, gas jetted out from an inflator is supplied to the front-and-rear chambers, which inflate and expand to a front side along left and right sides of the head of a vehicle occupant. In association with the inflation and expansion of the front-and-rear chambers, the airbag main body moves to the front side, passing between the head of the vehicle occupant and a vehicle cabin ceiling. The gas is supplied from the front-and-rear chambers to the airbag main body, which inflates and expands and is disposed at the front side of the vehicle occupant.

Abstract: A left-right pair of rear tethers is configured such that one-end portions thereof are anchored to a left-right pair of front-rear extension portions, other-end portions thereof are anchored to a seatback or to the vehicle body, and during passenger restraint each of a left-right pair of front-rear extension portions is pulled relatively in a seat diagonally rearward and downward direction such that a coupling portion approaches a femur area of a passenger.

Abstract: A vehicle passenger protecting device includes: a side airbag installed in a side portion at an outer side of a seatback of a vehicle seat, and inflating and expanding toward an outer side of a passenger seated on the vehicle seat due to gas being supplied at a time of a side collision of a vehicle; and a curtain airbag installed in at least a roof side rail, and inflating and expanding toward a vehicle lower side due to gas being supplied at a time of a side collision of the vehicle. The curtain airbag has an enlarged inflating portion that overlaps a center of a head of the passenger as seen in a side view, when the vehicle seat has been slid to a predetermined position at a vehicle rear side and the seatback has been set in a relaxed posture of being reclined to a recommended limit position.

Abstract: The occupant restraint device for a vehicle includes a seatbelt, which restrains an occupant P sitting on a vehicle seat at the vehicle seat, and a belt backing airbag. When gas is supplied to the belt backing airbag from an inflator at a time of frontal collision of the vehicle, the belt backing airbag inflates and expands between at least the shoulder belt of the seatbelt and the shoulder area of the occupant. Together with moving to a vehicle front side to follow the occupant moving to the vehicle front side due to inertial force, the belt backing airbag moves along the shoulder belt and maintains the state in which the belt backing airbag is interposed between at least the shoulder area of the occupant and the shoulder belt.

The side airbag for a head is configured so as to inflate and expand only in a case in which a seatback of the vehicle seat has been reclined by a predetermined angle or more.

Abstract: At the time of the vehicle front collision, whether to deploy only the front-collision airbag or both the ceiling airbag and the front-collision airbag among the ceiling airbag accommodated above the occupant seated on the seat and the front-collision airbag accommodated in front of the occupant is switched according to the front-rear slide position and the seat back angle of the seat.

Abstract: A vehicle occupant restraint device includes a seat belt, a belt support airbag, and a belt covering member. The seat belt restrains the occupant seated on a seat cushion of a vehicle seat to the vehicle seat. The belt support airbag is provided in a folded state in a lap belt or a shoulder belt of the seat belt and is inflated and deployed by gas supplied in an event of a frontal collision of a vehicle. The belt covering member covers at least a predetermined region of the lap belt on a belt anchor side and urges the lap belt downward when the seat belt is released.

Abstract: The occupant restraint device for a vehicle includes a three-point seatbelt device, a front impact airbag and a belt backing airbag. The three-point seatbelt device restrains the occupant, who is sitting on a vehicle seat, at the vehicle seat. The front impact airbag inflates and expands from a vehicle front side toward the occupant when gas is supplied from an inflator at a time of frontal collision of the vehicle. When gas is supplied to the belt backing airbag from another inflator at a time of frontal collision of the vehicle, the belt backing airbag inflates and expands so as to extend in a seat width direction between the shoulder belt of a seatbelt of the seatbelt device and the shoulder areas of the occupant. The belt backing airbag restrains both of the shoulder areas of the occupant, including clavicles of the occupant.
