The invention relates to a double-layer inflatable belt strap, used especially for a seat belt, which is characterized in that it is woven as a hose-like belt strap (2) having two woven layers (41, 42), namely an upper woven layer (42) and a lower woven layer (41), that in central areas (MB) of the two woven layers (41, 42) of the belt strap (2) which are approximately as wide as a conventional belt strap (2) the total breaking load of the warp threads (43, 44) corresponds to that of the warp threads of a conventional (seat belt) belt strap, and in that the warp threads of the border areas (RB) adjoining the central areas (MB) and the pick threads of the belt strap are finer than the warp threads (43, 44) in the central areas. The invention is further characterized in that the woven material of the border areas (RB) adjoining the central areas (MB) is folded along outer folding edges running parallel to the longitudinal direction of the belt strap in such a way that the woven material comes to rest between the central areas of the upper and lower woven layer, and in that the central areas of the upper woven layer and the lower woven layer are removably joined to each other in the area adjoining the outer folding edges. |
