Abstract
Abstract A gas bag has at least one inflatable chamber formed from textile wall pieces, and a seam edging this chamber. To considerably facilitate the stowing or folding of the gas bag in a housing or the like, guide elements in at least one seam region are provided for a traction means arranged parallel to the longitudinal direction of the seam, and the traction means is secured on an end region of the seam.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
Apparatus comprising: a gas bag with at least one inflatable chamber formed from at least one textile wall piece, said gas bag including a seam edging said chamber; a housing for receiving said gas bag in a folded state; a traction means arranged parallel to a longitudinal direction of said seam and being fastened on an end region of said seam; and guide elements on said gas bag for guiding said traction means in at least one seam region of said gas bag; said gas bag being transferred into said folded state in said housing through the exerting of force on a free end of said traction means.
Claim 2
Dependent Claim
108 words
Apparatus comprising: a gas bag with at least one inflatable chamber formed from at least one textile wall piece, said gas bag including a seam edging said chamber; a housing for receiving said gas bag in a folded state; a traction means arranged parallel to a longitudinal direction of said seam and being fastened on an end region of said seam; and guide elements on said gas bag for guiding said traction means in at least one seam region of said gas bag; said gas bag being transferred into said folded state in said housing through the exerting of force on a free end of said traction means.
Claim 3
Dependent Claim
38 words
A gas bag according to claim 1, wherein the gas bag has an elongated shape in said folded state and its folding is brought about by the exerting of traction on several traction means distributed over its length.
Claim 4
Dependent Claim
33 words
A gas bag according to claim 2, wherein the inflatable chamber is divided by several seam strips into individual chamber compartments and one traction means is arranged along each of said seam strips.
Claim 5
Dependent Claim
45 words
A gas bag according to claim 1, wherein said guide elements are formed by slits arranged transversely to said longitudinal direction of said seam in the latter, through which slits said traction means extends on alternate sides of the wall pieces of the gas bag.
Claim 6
Dependent Claim
39 words
A gas bag according to claim 1, wherein a detent-, locking or holding element is provided on said traction means, which engages on a corresponding counter element of said housing and holds said traction means in a tensioned state.
Claim 7
Dependent Claim
28 words
A gas bag according to claim 5, wherein said traction means is provided with a nominal tear line oriented transversely to a longitudinal direction of said traction means.
Claim 8
Dependent Claim
36 words
Apparatus as defined in claim 1, wherein said housing engages said gas bag in a region opposite said end region of said seam when said gas bag is transferred into said folded state in said housing.
Claim 9
Dependent Claim
109 words
Apparatus comprising: a gas bag having at least one inflatable chamber, said gas bag including an upper edge and a lower edge spaced apart from said upper edge; a housing for receiving said gas bag in a folded state; and traction means having a first end connected to said gas bag near said lower edge of said gas bag, said traction means extending through guide elements on said gas bag and extending along alternate sides of said gas bag; said gas bag being transferred into said folded state in said housing through the exerting of a force on a second end of said traction means opposite said first end.
Claim 10
Dependent Claim
109 words
Apparatus comprising: a gas bag having at least one inflatable chamber, said gas bag including an upper edge and a lower edge spaced apart from said upper edge; a housing for receiving said gas bag in a folded state; and traction means having a first end connected to said gas bag near said lower edge of said gas bag, said traction means extending through guide elements on said gas bag and extending along alternate sides of said gas bag; said gas bag being transferred into said folded state in said housing through the exerting of a force on a second end of said traction means opposite said first end.
