Abstract
Abstract A vehicle occupant protection apparatus ( 10 ) includes an inflatable vehicle occupant protection device ( 14 ) which is folded so as to be deployed from a reaction structure ( 24 ) in a first direction to restrain movement of a vehicle occupant in a second, opposite direction. The folded protection device ( 14 ) has a cross-section with a configuration defined by pleats ( 110 ). Each pleat ( 110 ) has an open end ( 112 ) and a closed end ( 114 ) spaced from the open end ( 112 ) in a direction substantially parallel to the first and second directions. An inflator ( 12 ) is received within one of the pleats ( 110 ′) and has inflation fluid outlet openings ( 124 ) adjacent to the closed end ( 114 ) of the pleat ( 110 ′). A retainer ring ( 56 ) engages and supports a peripheral edge portion ( 72 ) of the folded protection device ( 14 ) in an open configuration. The bag retainer ring ( 56 ) and the edge portion ( 72 ) of the folded protection device ( 14 ) are spaced fully from the inflator ( 12 ) on opposite sides of the pleated cross-section of the folded protection device ( 14 ).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
Apparatus comprising: an inflatable vehicle occupant protection device which is folded so as to be deployed from a reaction structure in a first direction to help restrain movement of a vehicle occupant in a second, opposite direction, said folded protection device having a cross-section with a configuration defined by pleats, each of said pleats having an open end and a closed end spaced from said open end in a direction substantially parallel to said first and second directions; an inflator received within one of said pleats, said inflator having inflation fluid outlet openings adjacent to the closed end of said one pleat; and a retainer ring engaging and supporting a peripheral edge portion of said folded protection device in an open configuration, said retainer ring and said edge portion being spaced from said inflator on opposite sides of said cross-section.
Claim 2
Dependent Claim
140 words
Apparatus comprising: an inflatable vehicle occupant protection device which is folded so as to be deployed from a reaction structure in a first direction to help restrain movement of a vehicle occupant in a second, opposite direction, said folded protection device having a cross-section with a configuration defined by pleats, each of said pleats having an open end and a closed end spaced from said open end in a direction substantially parallel to said first and second directions; an inflator received within one of said pleats, said inflator having inflation fluid outlet openings adjacent to the closed end of said one pleat; and a retainer ring engaging and supporting a peripheral edge portion of said folded protection device in an open configuration, said retainer ring and said edge portion being spaced from said inflator on opposite sides of said cross-section.
Claim 3
Dependent Claim
41 words
Apparatus as defined in claim 1 wherein said retainer ring has a rectangular peripheral shape, said cross-section of said folded protection device extending across the width of said retainer ring and being uniform along the entire length of said retainer ring.
Claim 4
Dependent Claim
30 words
Apparatus as defined in claim 1 wherein said cross-section of said folded protection device extends diametrically across said folded protection device and is uniform entirely around said folded protection device.
Claim 5
Dependent Claim
32 words
Apparatus as defined in claim 1 wherein said cross-sectional configuration of said folded protection device is free of overlapping plies of folded material extending transversely relative to said first and second directions.
Claim 6
Dependent Claim
128 words
Apparatus comprising: an inflatable vehicle occupant protection device which is folded so as to be deployed from a reaction structure in a first direction to help restrain movement of a vehicle occupant in a second, opposite direction, said folded protection device having a configuration defined by pleats, each of said pleats having an open end and a closed end spaced from said open end in a direction substantially parallel to said first and second directions; an elongated inflator received within one of said pleats; and a rectangular retainer ring engaging and supporting a peripheral edge portion of said folded protection device in an open configuration, said folded protection device extending across the width of said retainer ring and being uniform along the entire length of said retainer ring.
Claim 7
Dependent Claim
128 words
Apparatus comprising: an inflatable vehicle occupant protection device which is folded so as to be deployed from a reaction structure in a first direction to help restrain movement of a vehicle occupant in a second, opposite direction, said folded protection device having a configuration defined by pleats, each of said pleats having an open end and a closed end spaced from said open end in a direction substantially parallel to said first and second directions; an elongated inflator received within one of said pleats; and a rectangular retainer ring engaging and supporting a peripheral edge portion of said folded protection device in an open configuration, said folded protection device extending across the width of said retainer ring and being uniform along the entire length of said retainer ring.
Claim 8
Dependent Claim
46 words
Apparatus as defined in claim 5 wherein said pleated configuration is defined by a single layer of material which is folded to define said pleats, said folded protection device including multiple overlapping layers of folded material at locations outward of the opposite ends of said inflator.
