Abstract

A method of folding is provided for folding an airbag including a vehicle-side wall, a driver-side wall, an inlet opening formed in the vehicle-side wall and a mounting seat disposed in a periphery ofthe opening. The method includes a first process conducted in a first direction and a second process conducted in a second direction orthogonal to the former. The first process includes an initial folding that folds back each of opposite sides in the first direction of the airbag as flattened with respect to the mounting seat towards the mounting seat, a rolling that rolls the airbag towards themounting seat from creases formed in the initial folding, and an invaginating that invaginates each of resulting rolled regions between the vehicle-side and driver-side walls. The second process foldsup opposite sides in the second direction of the airbag with respect to the mounting seat each towards the mounting seat.

Description

technical field [0001] The present invention relates to a method of folding an airbag for a driver's seat mounted on a steering wheel of a vehicle. Background technique [0002] In the airbag of a conventional airbag device for a driver's seat, the vehicle body side wall portion is configured to have a boss portion in the vicinity of the center of an annular portion that is gripped when the steering wheel is turned, folded and accommodated, Supported on the side of the annular portion when inflating the gas for inflation; and the driver side wall portion, which connects the outer peripheral edge with the outer peripheral edge of the vehicle body side wall portion and is arranged on the driver's side (for example, refer to Japanese Patent Laid-Open 2006-290325 Bulletin). In the vicinity of the center of the side wall of the vehicle body, an inflow opening through which inflation gas flows is arranged, and the peripheral edge of the inflow opening is used as a mounting seat f...
