Title:
AIR BAG FOLDING, PROCESS AND DEVICE FOR FOLDING AIR BAGS
Document Type and Number:
WIPO Patent Application WO1997012782
Kind Code:
A3
Abstract:
A way of folding an air bag used in an air bag module is disclosed, as well as a process and device for folding an air bag. The air bag is folded in the direction of an imaginary longitudinal axis, forming a ring with separate folds at its inner and outer sides, the imaginary longitudinal axis preferably extending through the filling mouth of the air bag. The folding process is characterized in that the empty air bag is stretched in the direction of an imaginary longitudinal axis and folded up in the direction of the longitudinal axis within a boundary, in particular a boundary having a ring-shaped cross-section. A device for folding the air bag has a molded part, at least one device for introducing the air bag into the molded part and at least one device for compressing the air bag inside the molded part. The advantage of the invention is that only a few process steps and a simple device are required for folding the air bag.
