Patent ID: 8302991

Claim:
A method of folding a knee airbag assembly having a connection part and an airbag, the airbag defining a centerline, opposing side surfaces and an end located opposite the connection part, and having a front panel facing an occupant and a rear panel facing the front panel, the front panel having at least one folded over and sewn portion defining a wrinkle part adjacent one of the side surfaces and oriented in a vertical direction, the method comprising the steps of: roll-folding one of the side surfaces toward the centerline; roll-folding the other of the side surfaces toward the centerline; after the steps of roll-folding both of the side surfaces, vertical roll-folding of the airbag from the end and toward the connection part to form a folded knee airbag assembly; and wherein, in the steps of roll-folding the side surfaces, the side surfaces are roll-folded at an inclination angle such that both ends formed by the roll-folding of the side surfaces are inclined with respect to the centerline thereby preventing the sewn portion and the wrinkle part from being rolled up upon themselves during the vertical roll-folding step.
