VEHICLE PASSENGER PROTECTING DEVICE

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.
