1. A tubular guide element for guiding gas coming from a gas generator into a gas chamber of an airbag, the tubular guide element comprising:
- a first fabric cutting with two substantially parallel first edges which are connected with each other by a connecting seam such that the first cutting forms the outer skin of a tube; and
a second fabric cutting having two third edges that are disposed opposite of each other, wherein the first and second fabric cuttings are connected with each other such that the second fabric cutting is disposed inside the tube formed by the first fabric cutting and at least one of the third edges is positioned longitudinally inside the tube spaced apart from the connecting seam so that the second fabric cutting spans across and covers at least a section of the connecting seam to protect the connecting seam from being damaged by the gas from the gas generator.

12. A side curtain airbag unit comprising:
-
a deflector element including an inner layer and an outer layer both of which are made of fabric and are folded to form a cylindrical body which is held together by a first connecting line, the inner layer having two edges disposed opposite of each other wherein at least one of the edges of the inner layer is positioned longitudinally inside the cylindrical body spaced apart from the first connecting line so that the inner layer spans across and covers the first connecting line; a gas generator for generating gas; an airbag skin with an upper edge extending from a front end to a rear end, wherein an area of the upper edge located between the front and rear ends defines an accommodation area, wherein the gas generator is at least partially disposed within the deflector element and the deflector element is disposed within the accommodation area such that the gas from the gas generator is received by the accommodation area. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
