Abstract
Abstract A supplemental restraint system including an air bag for use in a vehicle to restrain an occupant during a sudden deceleration or collision. The air bag is folded in a hexagon configuration and mounted on a generally circular base unit such that the shape of the air bag, as folded, generally complements the shape of the base unit, thereby facilitating reducing unused space.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
62 words
A supplemental inflatable restraint system, comprising: a base; an air bag mounted to said base, said base having a generally hexagonal shape; and an inflator in fluid communication with said air bag for inflating said air bag; said air bag having a multi-sided fold configuration which generally complements the shape of said base when said air bag is installed in said base.
Claim 2
Dependent Claim
62 words
A supplemental inflatable restraint system, comprising: a base; an air bag mounted to said base, said base having a generally hexagonal shape; and an inflator in fluid communication with said air bag for inflating said air bag; said air bag having a multi-sided fold configuration which generally complements the shape of said base when said air bag is installed in said base.
Claim 3
Dependent Claim
54 words
The supplemental inflatable restraint system as set forth in claim 1 wherein said configuration comprises an air bag folded into a pleat fold stack having at least one transverse fold; wherein said pleat fold stack is folded to provide said pleat fold stack in a shape that generally complements the shape of said base.
Claim 4
Dependent Claim
53 words
The supplemental inflatable restraint system as set forth in claim 2 wherein said pleat fold stack is folded to form a plurality of transverse folds that converge at or near an axis of symmetry of said base to provide said air bag in a shape which generally complements the shape of said base.
Claim 5
Dependent Claim
44 words
The supplemental inflatable restraint system as set forth in claim 2 wherein said pleat fold stack is divided into a first pleat stack and a second pleat stack; said first and second pleat stacks extending away from said axis of symmetry of said base.
Claim 6
Dependent Claim
38 words
The supplemental inflatable restraint system as set forth in claim 1 wherein said multi-sided fold configuration comprises a first pleat stack and a second pleat stack; said first and second pleat stacks extending laterally away from said base.
Claim 7
Dependent Claim
38 words
The supplemental inflatable restraint system as set forth in claim 5 wherein said first pleat stack and said second pleat stack are folded in a generally transverse fashion to provide said air bag in said multi-sided fold configuration.
Claim 8
Dependent Claim
38 words
The supplemental inflatable restraint system as set forth in claim 6 wherein said first pleat stack and said second pleat stack are transversely folded outwardly from said base to provide said air bag in a generally hexagonal shape.
Claim 9
Dependent Claim
47 words
The supplemental inflatable restraint system as set forth in claim 1 wherein said air bag is folded laterally from opposite sides of said air bag inward toward a center portion thereof to provide a pleat stack having a width generally equal to the width of said base.
Claim 10
Dependent Claim
36 words
The supplemental inflatable restraint system as set forth in claim 8 wherein said pleat stack is transversely folded onto itself to provide said air bag with a shape that generally complements the shape of said base.
Claim 11
Independent Claim
89 words
A method of supplementarily restraining a vehicle occupant comprising the steps of: providing a module assembly having a receiving area for receiving an air bag, said receiving area being generally hexagonal in shape, said module assembly including an inflator for inflating said air bag; transversely folding said air bag such that the shape of said air bag becomes multi-sided and generally hexagonal in shape and generally complements the hexagonal shape of said receiving area; and positioning said air bag within said receiving area in operative relationship with said inflator.
Claim 12
Independent Claim
89 words
A method of supplementarily restraining a vehicle occupant comprising the steps of: providing a module assembly having a receiving area for receiving an air bag, said receiving area being generally hexagonal in shape, said module assembly including an inflator for inflating said air bag; transversely folding said air bag such that the shape of said air bag becomes multi-sided and generally hexagonal in shape and generally complements the hexagonal shape of said receiving area; and positioning said air bag within said receiving area in operative relationship with said inflator.
Claim 13
Dependent Claim
49 words
The method of supplementarily restraining a vehicle occupant as in claim 10 wherein said transverse folding step further includes the step of pleating said air bag inward from opposing lateral edges to provide a pleat fold stack with a width generally equal to the width of said receiving area.
Claim 14
Dependent Claim
54 words
The method of supplementarily restraining a vehicle occupant as in claim 10 wherein the step of transversely folding said air bag further comprises the step of forming a first pleat portion and a second pleat portion, said first and said second pleat portions extending laterally away from a central portion of said module assembly.
Claim 15
Dependent Claim
67 words
The method of supplementarily restraining a vehicle occupant as in claim 10 wherein the step of transverse folding said air bag further comprises the step of folding a first pleat portion and a second pleat portion inwardly toward a central portion of said module assembly to provide said air bag in a folded condition that generally complements the shape of said receiving area of said module assembly.
Claim 16
Dependent Claim
49 words
A supplemental inflatable restraint system, comprising: a base; an air bag mounted to the base; an inflator in fluid communication with the air bag for inflating the air bag; and the air bag having a multi-sided fold configuration to produce a folded pleat stack having a generally hexagonal shape.
Claim 17
Dependent Claim
49 words
A supplemental inflatable restraint system, comprising: a base; an air bag mounted to the base; an inflator in fluid communication with the air bag for inflating the air bag; and the air bag having a multi-sided fold configuration to produce a folded pleat stack having a generally hexagonal shape.
Claim 18
Dependent Claim
42 words
The supplemental inflatable restraint system of claim 14 wherein the folded pleat stack includes first and second laterally extending pleat stack arms, each of the pleat stack arms folded onto itself to provide the folded pleat stack having a generally hexagonal shape.
Claim 19
Dependent Claim
46 words
The supplemental inflatable restraint system of claim 15 wherein the pleat stack arms each include a lateral outermost end portion and wherein the lateral outermost end portions of the pleat stack arms overlap each other when the folded pleat stack is in the generally hexagonal shape.
Claim 20
Dependent Claim
55 words
The supplemental inflatable restraint system of claim 15 wherein the pleat stack arms each include a series of generally triangular folds including a final triangular fold and a second to the final triangular fold and wherein each of the final triangular folds also triangularly folds over the second to the final triangular fold onto itself.
