Abstract

A passenger-seat airbag includes a left airbag (44) and a right ajrbag (46), a root portion (48) connects a left-airbag root portion and a right-airbag root portion. An accordion-folded portion (72) with relatively small folding widths is formed by accordion-folding both side portions of the root portion (48), whereby at least a gas-injection hole (70A) closest to each of both ends of an inflator (28) in a longitudinal direction among a plurality of the gas-injection holes (70) of the inflator (28) is prevented from being closed by the root portion (48) when the passenger-seat airbag is provided in a vehicle.

Description

technical field [0001] The present invention relates to a passenger seat airbag device in which the passenger seat airbag is inflated and deployed upon a frontal collision, and to a folding method of the passenger seat airbag folded and stored in the passenger seat airbag device. Background technique [0002] Conventionally, a passenger seat airbag device is provided in order to protect a passenger seated on a passenger seat from impact in a frontal collision. Japanese Patent Application Laid-Open No. JP-A-2004-268903 describes an example of a passenger seat airbag device in which the passenger seat airbag includes a pair of left and right airbags, and a pair of left and right airbags is formed between the left and right airbags. between the recesses. When the passenger seat airbag begins to deploy, the passenger seat airbag accommodates various areas of the passenger's body, such as the shoulders. As a result, the load applied to the passenger is distributed and reduced. ...
