A completely folded body of an airbag, includes: an outer peripheral wall including a vehicle body side wall portion, and a receiving side wall portion. An outer peripheral edge side in a state where the receiving side wall portion is superimposed on the vehicle body side wall portion and is flatly deployed is subjected to radial folding and folded. An accommodation recess portion for accommodating an upper portion on a gas supply port side of an inflator is provided on a bottom surface. A radially-folded folded portion is disposed so as to surround a circumference of an intermediate portion from a base portion near the center of the ceiling surface of the accommodation recess portion in a linear supply path, for supplying the inflation gas from the inflator, to a tip portion disposed on an inner surface side near the center of the receiving side wall portion.

Completely folded body of airbag and folding method for same

An airbag device includes: an airbag which inflates from a state of a folded body by receiving an inflation gas; and a wrapping material wraps the folded body. The folded body has a three-dimensional shape including a bottom surface portion, a ceiling portion, and a side surface portion. The wrapping material includes: a cover member having flexibility and a sheet shape which includes a ceiling cover portion covering the ceiling portion of the folded body, a side surface cover portion covering the side surface portion, and a bottom surface cover portion which covers the bottom surface portion and has a locking hole to be locked to a fastener, and an elongation regulating member which is provided on at least a part of the cover member so as to suppress elongation of the cover member in opposition to an acting direction of the restoring force of the folded body.

Airbag device

A completely folded body of an airbag includes: a folded body and a retainer, which is assembled to the folded body, including: an annular bottom wall portion; a plurality of fixing units; and a reinforcing rib, wherein: the folded body of the airbag is configured in such a folded shape that the airbag is folded to be gathered to an upper side of the retainer; the folded body is arranged with a bottom wall cover portion and a bottom wall separated portion which extends from the bottom wall cover portion; and the bottom wall separated portion includes a stepped surface having a vertical surface bent upward from the bottom wall cover portion, and a horizontal surface which is disposed above the bottom wall cover portion from an upper end of the vertical surface and extends toward an outer circumferential edge of the bottom wall separated portion.

An actuator AEincludes a lock mechanism Rconfigured to fill a gas G generated by operating a gas generatorat inside of a cylinderand moving forward a pistonalong with a support rodfor restricting a rearward movement of the support rod moved forward. The support rodis arranged to be able to absorb a kinetic energy of a protection object person and capable of being plastically deformed when the protection object person is received by a receiving member after having been moved forward. A lock mechanism Ris constituted by a diameter enlarging deformed portionarranged at a piston and a locking stepped portioncapable of restricting the rearward movement of the piston. Further, the diameter enlarging deformed portionis locked by the locking stepped portionby being elastically deformed by an elastic force of the diameter enlarging deformed portionper se from a diameter contracting state to a diameter enlarging state when arranged to the locking stepped portionafter moving the piston forward.
