The present invention relates to a driver seat airbag device for a vehicle and a method for manufacturing same, the driver seat airbag device comprising: a driver seat airbag mounted in a folded state inside a steering wheel; and an inflator connected to the driver seat airbag to supply gas to allow the driver seat airbag to expand between the steering wheel and a driver at the time of a vehicle collision, wherein: the driver seat airbag has a plurality of tether members and a diffuser installed thereat, the tether members restricting an expansion thickness of the driver seat airbag, the diffuser controlling a supply direction for a gas supplied to the driver seat airbag, the tether members and the diffuser being installed between a front panel facing the front side of the vehicle and a rear panel opposite to the front panel and facing the driver; and the diffuser is installed between the plurality of tether members, and thus the diffuser and the tether members are integrated to simplify an installation structure thereof.

An airbag module according to various implementations includes an inflatable cushion, an inflator, and a pre-fold. The inflatable cushion includes a first panel and a second panel, each of the first and second panels including an outer surface. The first panel and the second panel are folded to form a first tuck and a second tuck. A protruding portion of the first and second panels is then folded into or adjacent to the first or second tuck to form the pre-fold.

An apparatus for helping to protect an occupant of a seat in a vehicle having an instrument panel and a housing positioned therein includes an airbag for positioning in the housing and defining an inflatable volume for receiving inflation fluid from an inflator. The airbag includes an occupant-facing panel. A tether extends along a centerline and has a first end connected to a portion of the airbag positioned within the housing and a second end connected to the occupant-facing panel for forming a pocket therein. The second end includes a folded-over portion. Stitching extends through the folded-over portion in a direction extending transverse to the centerline.

An airbag cushion for a vehicle may include: a front panel disposed in a direction facing a passenger when the airbag cushion is inflated, and having a front sewed part formed along the edge thereof; and a rear panel coupled to the front panel so as to form a chamber therebetween, having a gas introduction hole to introduce gas into the chamber, and having a rear sewed part formed along the edge thereof, the rear sewed part being coupled to the front sewed part, wherein the rear sewed part has a curvature part formed in a curved shape at the portion coupled to the front sewed part.

A side airbag that is to be inflated and deployed to a side of an occupant, includes: a first chamber that is positioned in an upper portion and is to be inflated to a side of a shoulder part of the occupant; and a second chamber that is on a lower side of the first chamber, and a thickness regulating member for reducing an inflation thickness is provided at an upper portion of a front portion of the second chamber.

A side airbag device for restraining an occupant at an early stage by changing a thickness of a chamber includes a cushion formed in a bag shape by combining an outer panel located at an outer side in a vehicle width direction and an inner panel located at an inner side in the vehicle width direction. A baffle spans between the outer panel and the inner panel in an inside of the cushion and partitions the inside of the cushion into a front chamber located at a vehicle front side and a rear chamber located at a vehicle rear side. An inflator is disposed in the rear chamber, and a first tether and a second tether extend from the baffle toward a vehicle rear. The tethers respectively extend from the baffle via both sides of the inflator in the vehicle width direction so as to be connected with a rear end of the cushion.

A method for manufacturing a one-piece woven (OPW) air bag includes method for manufacturing an OPW airbag. The method includes providing yarns, warping the yarns on at least one beam of a loom, and simultaneously weaving yarns into a fabric air bag structure having two layer portions defining an inflatable volume and single layer portions forming seams delimiting the inflatable volume. A plurality of the yarns overlay one another to form nonwoven alignment elements in at least one of the single layer portions. The air bag structure is cut to define the OPW air bag. The alignment elements are aligned with alignment elements on a panel. The air bag structure is sewn to the panel with the alignment elements aligned with one another.

A method of manufacturing an airbag includes fixing a first reinforcement panel to a first main panel at a first edge of the first main panel. The method includes fixing a second reinforcement panel to a second main panel at a second edge of the second main panel. The method includes overlaying the first main panel on the second main panel with the first reinforcement panel aligned with the second reinforcement panel and the first edge aligned with the second edge. The method includes fixing the first main panel to the second main panel along the first edge and the second edge. The method includes creating a vent by cutting both the first reinforcement panel and the second reinforcement panel along a cut line to form the vent.

The present disclosure relates to a curtain airbag apparatus having a twist prevention structure, and it is possible to mark a strap line 300 extending in a straight shape on a strap part 210 of a tab strap 200 for fixing a curtain airbag cushion 100 folded in a roll form, and easily check whether the curtain airbag cushion 100 folded in the roll form is twisted with the naked eye through the strap line 300.

Provided are an airbag base cloth and an airbag including same, the airbag base cloth being a flexible and lightweight airbag fabric on which films are laminated, having good rubbing resistance after withstanding heat/wet heat, and providing excellent internal pressure retention within the airbag after sewing. The airbag base cloth according to the present invention is characterized in that at least one face of fabric is coated with a multilayer film having an adhesive layer, and the average value of the warp and weft slippage resistance in the base cloth is 350 N/2.5 cm or more.
