1. A passenger protection system for a vehicle extending between forward and rearward directions, comprising:
a seat configured to slide in the forward and rearward directions and to rotate laterally, the seat including a seat belt equipped with a belt airbag;
a front airbag provided in a front structure located in front of the seat and configured to be deployed towards the seat;
a curtain airbag provided in a pillar trim on an upper end of a vehicle door and configured to be deployed downwards; and
a controller configured to selectively deploy the belt airbag, the front airbag and the curtain airbag, based on a sliding position and a rotating direction of the seat as well as detection of a vehicle collision or a predicted direction of the vehicle collision,
wherein, based on a direction where the seat faces a front of the vehicle, a side airbag is mounted on a side of a seatback of the seat adjacent to the vehicle door, and a far-side airbag is mounted on an opposite side of the seatback,
wherein the controller is further configured to:
selectively deploy the belt airbag, the side airbag, the far-side airbag, the front airbag and the curtain airbag, based on the sliding position and the rotating direction of the seat as well as the detection of the vehicle collision or the predicted direction of the vehicle collision,
deploy the front airbag when the seat is facing the side adjacent to the vehicle door in a head-on collision mode, and
deploy the far-side airbag when a distance between the seat or a passenger on the seat and the front structure is greater than a predetermined distance, or when a reclining angle of the seatback is greater than a predetermined angle.
