Abstract
An airbag cushion for use in a vehicle restraint system is provided.

A method of forming the cushion according to the present invention is also provided.
Claims32
An airbag cushion for use in a vehicle restraint system, the cushion comprising:
- a notched body panel having notches in boundary edges thereof;
- and
- a substantially rectangular frontal center panel;
- said notches of said body panel being seamed together along abutting edges thereof to fold said body panel and form a profile,
- said body panel and said center panel being seamed together along corresponding boundary edges of said body panel and around the entire perimeter of said center panel by a series of substantially straight seams thereby forming an inflatable structure.
An airbag cushion for use in a vehicle restraint system, the cushion comprising:
- a notched body panel having notches in boundary edges thereof;
- and
- a rectangular frontal center panel;
- said notches of said body panel being seamed together along abutting edges thereof to fold said body panel and form a profile, and
- said body panel and said center panel being seamed together along corresponding boundary edges of said body panel and around the entire perimeter of said center panel by a series of substantially straight seams thereby forming an inflatable structure whereby said seamed notches prevent said body panel from uncontrollable expanse.
An airbag cushion for use in a vehicle restraint system for protecting an occupant of a vehicle, the cushion comprising:
- a notched body panel having notches in the sides thereof and an inflator opening;
- a rectangular frontal center panel;
- said notches of said body panel being seamed together along abutting edges thereof to fold said body panel and form a profile, and
- said body panel and said cener panel being seamed together along corresponding boundary edges of said body panel and around the entire perimeter of said center panel by a series of substantially straight seams thereby forming an inflatable structure wherein said seamed notches prevent the body panel from excessive expansion to prevent said center panel from hitting an occupant of a vehicle with excessive force upon inflation of the airbag cushion.
