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.

Patent number: 6726245Abstract: The invention relates to a gas bag module comprising a gas bag with a gas bag wall which has a front and a rear wall section. A depression is provided which has a mouth and runs in an inflated state of the gas bag from the front wall section to the rear wall section, which depression is formed in that a part of the gas bag wall is prevented from an unimpeded movement away from the module on unfolding of the gas bag. The module further comprises at least one closure piece which is fastened to the gas bag wall such that in the inflated state it moves in front of the mouth of the depression and closes the depression.Type: GrantFiled: February 6, 2002Date of Patent: April 27, 2004Assignee: TRW Automotive Safety Systems GmbH & Co. KGInventors: Joachim Fellhauer, Stefan Bohn

Patent number: 6726244Abstract: An apparatus for folding an airbag for a vehicle occupant restraint system comprises a base for the airbag to be folded, a cover for the airbag, and a flexible element that is arranged between the base and the cover and has first and second ends. The first end of the flexible element is held between the base and the cover. The apparatus further comprises a traction means that acts upon the second end of the flexible element, and a pressure generating means with which the airbag can be acted upon with compressed gas. The invention further relates to a method of folding an airbag and making use of such an apparatus. Still further, the invention relates to a folded airbag produced by such a method.Type: GrantFiled: October 11, 2001Date of Patent: April 27, 2004Assignee: TRW Automotive Safety Systems GmbH & Co.

Patent number: 6655714Abstract: The invention relates to a gas bag restraint device including a gas bag module which has a gas bag wall. The gas bag wall has a front wall upon which an occupant to be restrained can impact in a case of restraint and has a depression defined by a ring-shaped gas bag wall portion. The depression is generated in that a center portion of the front wall is attached to the module and is prevented from movement when the gas bag is inflated. A holder is provided at the ring-shaped gas bag wall portion that keep parts of the ring-shaped gas bag wall portion, which get in contact with each other when the gas bag is inflated, in contact with each other in a fully inflated condition of the gas bag, and at least partly close the depression.Type: GrantFiled: December 26, 2001Date of Patent: December 2, 2003Assignee: TRW Automotive Safety Systems GmbH & Co.

Patent number: 6595549Abstract: A gas bag module comprises a gas bag which has a front wall for the impact of an occupant. The gas bag is formed by a gas bag wall of several fabric parts. At least one of the fabric parts forms the front wall having an opening from which, in an inflated state of the gas bag, a depression originates, which is formed in that a center section of the gas bag wall on inflation is prevented from a free movement and is held back. The gas bag has around the depression an annular chamber which is to be filled. The opening is constructed in a slit shape.Type: GrantFiled: July 11, 2001Date of Patent: July 22, 2003Assignee: TRW Automotive Safety Systems GmbH & Co., KGInventors: Stefan Bohn, Joachim Fellhauer

Patent number: 6588798Abstract: The invention relates to a gas bag module comprising a gas bag including a gas bag wall which has a front and a rear wall section and including at least one chamber. The gas bag further comprises an indentation running from the front wall section in an inflated state in a direction toward the rear wall section. The indentation is formed in that a part of the gas bag wall is prevented from an unimpeded movement towards outside of the module on unfolding of the gas bag. The gas bag, in a region of a mouth of the indentation, has a bubble-like inflatable extension in flow connection with the at least one chamber of the gas bag, which extension closes the indentation.Type: GrantFiled: January 30, 2002Date of Patent: July 8, 2003Assignee: TRW Automotive Safety Systems GmbH & Co.
