Abstract
Abstract An apparatus (10) includes an inflatable vehicle occupant protection device (12) and a housing (42) containing the protection device (12). The housing (42) has a seam (54). The apparatus (10) further includes a conduit (40) configured to convey inflation fluid to the protection device (12). The conduit (40) is deflectable under the influence of pressure forces applied by the inflation fluid, and is located adjacent to the seam (54) in the housing (42). The conduit (40) can thus transmit fluid pressure forces to the housing (42) along the seam (54) so as to open the housing (42) along the seam (54) upon deflecting under the influence of the fluid pressure forces. Preferably, the conduit (40) is a tubular extrusion extending along an elongated vehicle frame member (34) having a non-linear contour. The tubular extrusion (40) has a non-linear contour matching the non-linear contour of the frame member (34).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
85 words
Apparatus comprising: an inflatable vehicle occupant protection device; a housing containing said protection device, said housing having a seam; and a conduit configured to convey inflation fluid to said protection device; said conduit being deflectable under the influence of pressure forces applied by said inflation fluid; said conduit being located adjacent to said seam so as to transmit said pressure forces to said housing along said seam and thereby to open said housing along said seam upon deflecting under the influence of said pressure forces.
Claim 2
Dependent Claim
85 words
Apparatus comprising: an inflatable vehicle occupant protection device; a housing containing said protection device, said housing having a seam; and a conduit configured to convey inflation fluid to said protection device; said conduit being deflectable under the influence of pressure forces applied by said inflation fluid; said conduit being located adjacent to said seam so as to transmit said pressure forces to said housing along said seam and thereby to open said housing along said seam upon deflecting under the influence of said pressure forces.
Claim 3
Dependent Claim
34 words
Apparatus as defined in claim 1 wherein said protection device is interposed between said conduit and said seam so as to transmit said pressure forces from said conduit to said housing along said seam.
Claim 4
Dependent Claim
13 words
Apparatus as defined in claim 1 wherein said conduit is a tubular extrusion.
Claim 5
Dependent Claim
19 words
Apparatus as defined in claim 1 wherein said conduit is transversely extendible under the influence of said pressure forces.
Claim 6
Dependent Claim
14 words
Apparatus as defined in claim 4 wherein said conduit has a crescent shaped cross-section.
Claim 7
Dependent Claim
39 words
Apparatus as defined in claim 5 wherein said protection device is stored in an uninflated condition in which a folded portion of said protection device is received in a recess defined by said crescent shaped cross-section of said conduit.
Claim 8
Dependent Claim
52 words
Apparatus comprising: an elongated vehicle member having a non-linear contour; an inflatable vehicle occupant protection device; and a conduit configured to convey inflation fluid to said protection device; said conduit comprising a tubular extrusion extending along said member, said tubular extrusion having a non-linear contour matching said non-linear contour of said member.
Claim 9
Dependent Claim
52 words
Apparatus comprising: an elongated vehicle member having a non-linear contour; an inflatable vehicle occupant protection device; and a conduit configured to convey inflation fluid to said protection device; said conduit comprising a tubular extrusion extending along said member, said tubular extrusion having a non-linear contour matching said non-linear contour of said member.
Claim 10
Dependent Claim
27 words
