Problems solved by technology

However, since the connection panel connects the front ends of the left half airbag and the right half airbag, the airbag that starts to inflate first cannot be fully stretched by the connection panel until the airbag that inflates has reached its front end.

Abstract

An airbag apparatus receives an occupant's left breast by an expanded left airbag section and receives the right breast by a right airbag section. A void space of the expanded airbag opposes the lateral center of the occupant's breast. Both the left and right airbag sections expand smoothly and substantially evenly. The left and right airbag sections are folded firstly to obtain a first folded body elongated in the fore-and-aft direction and, subsequently, the distal sides from a joint belt, which connect the midsections in the expanding direction of the left and right airbag sections, are opened laterally apart from each other. The rear sides from the joint belt are folded so as to be reduced in width in the fore-and aft direction to obtain the second folded body, and then the lateral width is reduced by the third folding operation to obtain the final folded body.

Description

technical field [0001] The present invention relates to an airbag device having an airbag that inflates to protect an occupant during a vehicle collision, etc., and more particularly to an airbag apparatus having a left half airbag and a right half airbag that inflate on the left and right sides in front of the occupant, respectively. Furthermore, the present invention relates to a method of folding the airbag. Background technique [0002] JP-A-4-292239 discloses that an airbag for protecting the occupant when a vehicle collides, etc., has the following configuration: a left half airbag and a right half airbag respectively inflated on the left and right sides in front of the occupant, and through a common inflator for inflation. In the airbag disclosed in this publication, the front ends of the left-half airbag and the right-half airbag are connected by a connecting panel. [0003] The airbag is housed in a box after being folded and covered with a cover. When the vehicl...
