Abstract

An airbag of an airbag device for driver's seat of the invention is stored in a way that a carbody-side wall part and a driver-side wall part are overlapped and spread flat, and the airbag is folded in three steps so that widths between opposing outer edge portions with a gas opening as the center are reduced. In the first step of the folding, the carbody-side wall part and the driver-side wall part are overlapped and spread flat, and then right and left edge portions are folded toward the carbody-side wall so that wound regions are provided. In the second step of the folding, areas by front and rear edge portions are folded toward the driver-side wall, so that two regions that have been folded each cover approximately half the gas opening. In the third step, areas by the right and left edge portions that have been folded in the second step are folded in such a manner as to be bent upward. The airbag device for driver's seat of the invention can secure thickness of the neighborhood of a center of the airbag in the initial stage of expansion of the airbag.

Description

technical field [0001] The present invention relates to an airbag device for a driver's seat that can protect a driver by deploying an airbag when a vehicle collides. The airbag device for a driver's seat is mounted on an upper side of a hub in the center of a steering wheel. Background technique [0002] Conventionally, in the airbag device for a driver's seat described in JP-A-2003-170804, the airbag is housed in a folded state on the upper side of a hub in the center of the steering wheel. In addition, the airbag is held by the airbag holder, and is covered and accommodated by an openable door portion of the airbag cover. [0003] This airbag is configured to include a driver's side wall portion disposed on the driver's side on the upper surface side when inflation is completed, and a vehicle body side wall portion disposed on the steering wheel side on the lower surface side. Both of these driver's side wall parts and vehicle body side wall parts are formed in a substan...
