Abstract: An airbag device and a method for controlling deployment of the same are proposed. The airbag device is configured to protect a passenger by controlling an airbag cushion deployed toward the rear space of a seatback in an event of a vehicle collision, and the airbag device includes an airbag cushion deploying toward the rear space of the seatback, a sensor part detecting a seating status and a seating posture of a passenger with respect to each seat, and a controller, in an event of a collision, configured to change and control a deploying status of the airbag cushion and an inflation amount of the airbag cushion in response to the seating status and the seating posture of the passenger.

Abstract: Disclosed are a shoulder airbag and an airbag cushion thereof that are capable of restricting an occupant from being moved upward along a seatback and from being abruptly pushed in a direction away from a collision side of a vehicle when vehicle collision occurs, thereby safely protecting the occupant. The shoulder airbag includes an airbag cushion mounted in a seatback and configured to be deployed so as to cover each of the shoulders of an occupant sitting in a seat in three axis directions.

Abstract: The present invention relates to a two-phase, two-column linear pulse motor propulsion system, and more particularly to a two-phase, two-column linear pulse motor propulsion system which can implement high-speed driving, stopping, and switching directions forward/backward through non-adhesive driving characteristics by improving accelerating performance and torque performance. The two-phase, two-column linear pulse motor propulsion system comprises a field unit 121, 122 prepared in two columns in the longitudinal direction under a moving body 110 so as to generate a magnetic field; an armature unit 131, 132 which is prepared on a travelling track, generates a shifting field by the power supplied from a power conversion device, is prepared in two columns so as to correspond to the two-column field unit 121, 122 and generates the propulsion force of the moving body 110 through interaction due to a two-phase synchronous signal.
