Patent number: 6740025Abstract: A method of folding a gas bag for a vehicle occupant restraint system comprises the following steps: first, the gas bag is unfolded between a base and an opposing surface. A spacing is provided between the base and the opposing surface, which corresponds to a height of a housing into which the gas bag is to be inserted after folding. Then, a folding funnel is provided which comprises one end having a large cross-section and one end having a small cross-section, the large cross-section being larger than or equal to a cross-section of the gas bag when unfolded between the base and the opposing surface, and the small cross-section corresponding to a cross-section of the housing; beginning with its large cross-section. Finally, the folding funnel is placed over the unfolded gas bag and moved relative thereto such that the gas bag is pushed together on the base by the folding funnel to the small cross-section.Type: GrantFiled: September 13, 2002Date of Patent: May 25, 2004Assignee: TRW Automotive Safety Systems GmbH & Co.
