1. An airbag device for a vehicle having a first-row seat and a second-row seat, the airbag device comprising:
an airbag cushion disposed at a seatback of the first-row seat and configured, when inflated, to deploy from the seatback toward a rear space of the seatback;
a sensor configured to detect a seating status and a seating posture of a passenger seated at one of the first-row seat and the second-row seat; and
a controller configured, in response to an occurrence of a vehicle collision, to adjust deployment and an inflation amount of the airbag cushion based on the detected seating status and seating posture of the passenger,
wherein the controller is configured, in response to the occurrence of the vehicle collision, to control the airbag cushion to be deployed selectively at a first or second pressure based on the detected seating status and seating posture of the passenger, the second pressure being greater than the first pressure, and
wherein, in response to the detected seating status and seating posture of the passenger indicating that the passenger is seated at the second-row seat and facing in a forward direction of the vehicle, the controller is configured, in response to the occurrence of the vehicle collision, to control the airbag cushion to be deployed regardless of whether another passenger is seated at the first-row seat.
