First Claim
Patent Images
1. A multipart airbag cutting for an airbag of an occupant protection device for motor vehicles, it being possible for the airbag to be produced by connecting the edges of the airbag cutting, comprising:
- at least two mutually overlapping airbag parts connected to each other in an overlapping region;
a first airbag part, in the inflated state of the airbag, forming a covering which surrounds a first chamber of the airbag in a bell-shaped manner; and
a second airbag part forming a covering which encloses a second chamber of the airbag and, in the overlapping region, forms a boundary surface between two chambers of the airbag, in the region of which surface the two coverings of the inflated airbag are supported on each other to stabilize the airbag.

Abstract
The invention relates to an airbag cutting for an airbag of an occupant protection device for motor vehicles. Said cutting comprises two deployed, mutually overlapping airbag parts (1, 2; 3, 4) that are linked with each other in the area of overlap (U), and a folding axis (A) about which the two airbag parts (1, 2; 3, 4) can be folded in such a manner as to form an airbag having two separate compartments (K1, K2; K3, K4) by linking the airbag sections that lie one on top of the other after folding.

34. A method for producing an airbag from an airbag cutting comprising the steps of:
-
spreading out at least two airbag parts of the airbag so that they overlap each other; connecting the airbag parts to each other in the overlapping region so that one airbag part forms a covering which encloses one chamber of the airbag and forms a boundary surface between at least two chambers of the airbag; placing sections of the airbag cutting, which is composed of the airbag parts one above the other, so that they can be connected along the edge of the airbag cutting; and connecting the airbag sections, which lie one above the other, to each other to form an airbag, so that, in the inflated state of the airbag, one airbag part forms a covering which surrounds one chamber of the airbag in a bell-shaped manner and being supported on the covering of the airbag, which covering is formed by the first-mentioned airbag part in the region of the boundary surface to stabilize the airbag. - View Dependent Claims (35, 36)
