Abstract
A method of forming an airbag cushion (10, 10A) has the steps of providing placing the cushion in a vacuum bag (20) and evacuating the air shrinking the airbag cushion (10, 10A) to a compacted size; conforming the airbag cushion to a predetermined shape; placing the airbag cushion (10, 10A) in a high temperature environment between +50° C. to +140° for a predetermined time to thermally set the fabric material (120) to maintain the compacted airbag cushion (10, 10A) to the predetermined shape; and releasing the vacuum and removing the thermally set airbag cushion (10, 10A) from the vacuum bag (20
Claims12
A method of forming a folded airbag cushion (10, 10A) comprises the steps of:
- providing an airbag cushion made of fabric material (12);
- placing the cushion (10, 10A) in a vacuum bag (20) and evacuating the air to create a vacuum and shrinking the airbag cushion to a compacted size;
- placing the airbag cushion (10, 10A) in a high temperature environment between +50° C. to +140° for a predetermined time to thermally set the fabric material (12) to maintain the compacted airbag cushion shape;
- and
- releasing the vacuum and removing the thermally set airbag cushion (10, 10A) from the vacuum bag (20), the cushion maintaining the predetermined shape being formed as a mini pack or compacted airbag cushion (10, 10A).
