A folded body of a head protection airbag includes a compression section, and a non-compression section. The airbag includes a shield inflation section that covers the vehicle interior side of a window at a time of inflation completion. The shield inflation section includes: a primary development area developed and inflated in an initial stage of an inflow of the inflation gas; and a secondary development area disposed on a side of one end of the airbag in the front-rear direction so as to be inflatable by following development and inflation of the primary development area. The secondary development area is disposed in the compression section and the primary development area is disposed in the non-compression section.

A folding method of a far-side airbag apparatus may include: a first folding step of folding an upper portion of an airbag sheet toward an inboard side; a second folding step of folding both widthwise sides of the airbag sheet toward an outboard side; a third folding step of folding the upper portion of the airbag sheet toward the inboard side; and a fourth folding step of roll-folding the airbag sheet.

A method of folding a driver airbag that has a front airbag layer connected at least in portions to a rear airbag layer includes flatly spreading the airbag onto a support surface so that the front airbag layer comes to rest on the rear airbag layer. Each of an upper airbag portion and a lower airbag portion are zigzag folded multiple times in the direction of a transverse axis of the airbag. Each of a left-hand lateral airbag portion and a right-hand lateral airbag portion are furled in the direction of a longitudinal axis of the airbag.

In a method of folding a curtain-type side airbag (10) into an elongate airbag package (12) defining a longitudinal direction (L), wherein the side airbag (10) at one longitudinal end includes an elongate inflatable extension (14) having a free end (34), in a first folding step the extension (14) is folded over at a first folding line (30) enclosing an angle () <90, especially between 30 and 60, with the longitudinal direction (L), and in a second subsequent folding step the free end (34) of the extension (14) is folded over at a second folding line (36), the second folding line (36) enclosing an angle () of 0 to 45, especially 0, with the longitudinal direction (L).

A machine for folding a side curtain airbag which has a simpler machine configuration and is more efficient than a fully automatic machine and that can fold a large-capacity side curtain airbag cushion of approximately 4.0 m in length to sufficiently secure quality stability, and a process for folding a side curtain airbag by using the same, are provided.

A method of manufacturing a folded airbag comprising the steps of: providing an airbag cushion; heating the airbag material, folding the heated airbag material; compressing the folded airbag material obtained in step c) and optionally cooling the compressed airbag.

A method of forming an airbag cushion (10, 10A) has the steps of providing placing the cushion in a vacuum bag (20) and evacuating the air shrinking the airbag cushion (10, 10A) to a compacted size; conforming the airbag cushion to a predetermined shape; placing the airbag cushion (10, 10A) in a high temperature environment between +50 C. to +140 for a predetermined time to thermally set the fabric material (120) to maintain the compacted airbag cushion (10, 10A) to the predetermined shape; and releasing the vacuum and removing the thermally set airbag cushion (10, 10A) from the vacuum bag (20).

An airbag device includes an airbag provided with an inlet port of inflation gas, an inflator which includes gas outlet ports in an upper region of the body, a bag holder which is formed from synthetic resin and includes an insert opening for receiving the inflator body, and an airbag cover which includes a door openable at airbag deployment. The bag holder includes a support board which supports a bottom surface of the airbag as folded including a periphery of the inlet port, and a gas guide tube which extends upward from a periphery of the insert opening and is fitted in the inlet port of the airbag. The guide tube as fitted in the inlet port is greater in height than the upper region of the inflator body. The airbag further includes, in a vicinity of the bottom surface, a joint section which is joined to the support board.

A folded body of a head protection airbag includes a compression section, and a non-compression section. The airbag includes a shield inflation section that covers the vehicle interior side of a window at a time of inflation completion. The shield inflation section includes: a primary development area developed and inflated in an initial stage of an inflow of the inflation gas; and a secondary development area disposed on a side of one end of the airbag in the front-rear direction so as to be inflatable by following development and inflation of the primary development area. The secondary development area is disposed in the compression section and the primary development area is disposed in the non-compression section.

An airbag includes a panel foldable to a storage position. The panel includes a top, a bottom spaced from the top along an axis, and sides spaced from each other and extending from the top to the bottom. The panel includes a first stack of pleats extending from one of the sides to the other of the sides along the top, and a second stack of pleats extending from one of the sides to the other of the sides along the bottom. The panel includes a first portion extending from the axis to one side and a second portion extending from the axis to the other side. The first portion and the second portion, in the storage position, are each folded along a first fold towards the axis and along a second fold away from the axis.
