A roof airbag apparatus may include: a cushion having an inlet through which gas discharged from an inflator is introduced; a plurality of tethers connected to the cushion, and arranged along the edge of the cushion so as to be separated from each other; a plurality of steel tabs each having a connection hole formed therein; and a tether guide installed in a pillar shape through the connection holes, and supporting the cushion. The tethers may be connected to the cushion through the respective connection holes.

An inflatable safety restraint system that is downwardly deployable from a roof of a vehicle for protecting an occupant of the vehicle. The inflatable safety restraint system includes at least one inflatable airbag and at least one joint closing the shape of the at least one inflatable airbag to circumscribe an internal cavity. At least one inflator is in fluid communication with the at least one inflatable airbag for inflating the at least one airbag. Upon deployment, the inflatable safety restraint system defines a closed shape for surrounding the occupant of the vehicle.

A rooftop airbag apparatus including: a first cushion deployed along a ceiling of a vehicle body; a second cushion connected to the first cushion and deployed toward a bottom of the vehicle body; and a third cushion connected to the second cushion and deployed in a widthwise direction of the vehicle body.

An occupant protection system for a vehicle may include an expandable curtain and/or an expandable bladder configured to be expanded from a stowed state to a deployed state. In the deployed state, the expandable curtain may include first and second sides configured to extend along respective portions of first and second interior sides of the vehicle. The expandable curtain may also include a transverse portion extending between the first and second sides, and the first and second sides, and the transverse portion of the expandable curtain may form a contiguous barrier. The expandable bladder when deployed may be supported by the expandable curtain during contact by an occupant. The occupant protection system may also include a deployment control system configured to cause the expandable curtain and/or the expandable bladder to expand to the deployed state. The occupant protection system may be used in vehicles having a carriage-style seating arrangement.

A curtain airbag device for a vehicle including; a curtain airbag that includes tabs that are anchored at a roof side portion, stowed in the roof side portion in folded state, inflates and expands toward the vehicle lower side, and includes, at a front portion, a front seat oblique collision chamber that inflates to the vehicle lower side relative to a door beltline and is superposed in the vehicle width direction with a door trim; and a swing restriction tab projecting from upper edge portion of front portion of the curtain airbag, anchored at the roof side portion at the vehicle lower side with respect to an imaginary line that runs along the curtain airbag in folded state and passes through anchoring points of the tabs, and restricts upward swinging with respect to the vehicle by the front portion of the inflated and expanded curtain airbag.

A roof airbag apparatus including: a first cushion disposed on one side of a panoramic sunroof in a width direction of the panoramic sunroof and connected to an inflator; a second cushion disposed on the other side of the panoramic sunroof in the width direction and connected to the inflator; a first wire connected to the second cushion and connected to the first cushion to pull the second cushion toward the first cushion when the first cushion is deployed; a second wire connected to the first cushion and connected to the second cushion to pull the first cushion toward the second cushion when the second cushion is deployed; and guide anchors on which the first wire and the second wire are movably supported.

A roof airbag apparatus may include: a gas injection unit configured to discharge gas; a tether guide extending in a longitudinal direction of a roof; and an airbag configured to be deployed by gas transferred from the gas injection unit. The airbag may include: a first chamber part coupled to the tether guide and configured to be deployed in a longitudinal direction of the tether guide by gas transferred from the gas injection unit; and a second chamber part coupled to the first chamber part, and configured to be deployed by gas transferred from the first chamber part and cover the first chamber part.

An assembly includes a seat. The assembly includes a housing. The assembly includes an airbag inflatable to an inflated position having a first inflatable leg and a second inflatable leg extending from the housing, and an inflatable member extending from the first inflatable leg to the second inflatable leg. The assembly includes a tether having a first end fixed to the first inflatable leg and a second end spaced from the first end and the airbag.

A vehicle airbag system includes an airbag having a stiffened portion and an inflatable portion connected to the stiffened portion. A pocket is formed in the stiffened portion between first and second sewn seams. The pocket has a closed end wall defining a first end of the pocket and a pocket entrance defining a second end of the pocket. An elongated spline is disposed in the pocket through the pocket entrance, the spline when fully received in the pocket resisting torsional motion of the vehicle airbag system in an inflatable portion non-deployed condition.

An airbag package of an airbag for head protection includes a rolled portion formed by rolling a skin material of the airbag as laid flat, and a compressed region in which a void space formed at the center of the cross-sectional surface of the rolled portion has been crushed due to compression. The rolled portion includes, in the cross-sectional surface, an upper layered portion, a lower layered portion, and a pair of side layered portions that are disposed around the center of the cross-sectional surface of the rolled portion and each have layers of the skin material. In the compressed region, each of the side layered portions bends generally at the center in an up and down direction such that the bent regions butt against each other and are packed between the upper layered portion and the lower layered portion in such a manner as to fill the void space.
