Abstract: A driver airbag apparatus for vehicle with an illumination emblem, capable of preventing the deployment pressure of an airbag cushion 10 from being directly transmitted to a cover hinge part 43 of an airbag cover 40, thereby preventing the cover hinge part 43 from being broken due to the deployment pressure of the airbag cushion 10 and the departure of the illumination emblem 50 from a driver airbag module, by using a guide support 60 installed to cover the cover hinge part 43 of the airbag cover 40 at an inner position of the illumination emblem 50.

Abstract: A roof airbag apparatus may include: a cushion configured to cover a roof when deployed; a pair of guides having a length in the deployment direction of the cushion, and configured to guide both sides of the cushion in the deployment direction; and a deployment resistance reducer having a connector connected to one end of each of the guides so as to apply an elastic force from a first location toward the rear, wherein the connector is moved to a second location in a front of the first location by frictional resistance which is applied to the guide when the cushion is deployed.

Abstract: A roof airbag for a vehicle is proposed. The roof airbag for a vehicle has an airbag cushion configured to be unfolded downward from an inner roof to protect a passenger seated on a seat, and the airbag cushion has a shape bent toward the passenger by a main tether and a sub-tether, thus securing a restraining force for the passenger and safely protecting the passenger from an impact, and the airbag cushion is unfolded downward while avoiding insertion between a roof-side portion of the roof and a headlining by the sub-tether. Specifically, the airbag cushion is prevented from being transversally contracted and an unfolding shape of the airbag cushion is maintained. Furthermore, the fluidity of a gas flow in the airbag cushion is secured, so that the airbag cushion is rapidly unfolded.

Abstract: An airbag device of a vehicle and a control method thereof. The airbag device of a vehicle includes a detection unit configured to detect collision information of a vehicle and seating state information of an occupant, an airbag unit including a plurality of airbag modules, each of the airbag modules being configured to be inflated from a contracted state as working gas is supplied and to be restored to the contracted state as the working gas is discharged, a valve unit configured to regulate the working gas supplied to the airbag unit, and a control unit configured to determine a hitting position based on the collision information and the seating state information, and to control the valve unit to supply the working gas to a target airbag module installed at the hitting position, thereby inflating the target airbag module.
