Airbag folding method and folding device
First Claim
1. A method of folding an airbag, comprising the steps of:
- disposing a core member having an air suction hole thereon on a part of a spread airbag to be rolled up corresponding to a center of a rolled-up shape of the airbag;
rotating the core member while sucking air from the air suction hole of the core member so that the airbag is sucked on an outer circumferential surface of the core member and wound around the core member; and
removing the core member to thereby leave the airbag in the rolled-up shape.

Abstract
In an airbag folding method, an airbag is folded so as to provide a rolled-up shape thereon using a core member including air suction holes from which air can be sucked in. Firstly, the core member is disposed on part of the spread airbag that is to be rolled up at a location which corresponds to a center of a rolled-up shape when formed, and following this, the core member is rotated so as to wind up the airbag around the core member to thereby form a spiral shape while air is being sucked in from the air suction holes so that the airbag is drawn to be secured to an outer circumferential surface of the core member. Thereafter, a rolled-up shape is formed on the airbag by removing the core member.

3. A folding device for forming an airbag in a rolled-up shape, comprising:
-
a table on which a spread airbag is placed;
a core member having an air suction hole through which air is sucked for holding the airbag around an outer circumferential surface thereof;
an air suction source connected to the core member so as to suck air through the air suction hole; and
a rotary mechanism which supports and rotates the core member such that the airbag placed on the table is wound around the core member. - View Dependent Claims (4)
