Patent number: 6536549Abstract: The invention relates to a method for controlling the steering angle of a steered wheel of a vehicle and a system to carry out this method. A control unit (9) controls an adjustment drive (5, 7) to alter the steering angle of the steered wheel, upon an alteration to a position of a steering member (13). The extent of the alteration to the steering angle is dependent on whether an obstacle for the vehicle is detected or not by means of a distance meter (17) coupled with the control unit (9). If an obstacle is detected at high speeds, then steering angle alterations are possible which would not be permitted by the control unit at normal driving operation. Thereby, in emergency situations the driver is to be given the possibility of being able to drive past the obstacle by a steering response characteristic which is more intense.Type: GrantFiled: May 25, 2001Date of Patent: March 25, 2003Assignee: TRW Automotive Safety Systems GmbH & Co. KGInventor: Martin Kreuzer

Patent number: 6536801Abstract: A gas bag module has a gas bag with a gas bag wall. The gas bag wall has a front wall which faces an occupant to be restrained and has a center section, and a rear wall with an inflation opening to connect to a gas generator. A fastener fastens the center section to the module and prevents the center section from a free movement so that a depression is formed by the center section. A module covering has an annular, predetermined outlet opening which surrounds the fastening. The module covering has a holding section encircled by the outlet opening. An emblem adjoins the holding section. The emblem is fastened to the module by the fastener which fastens the center section of the wall to the module.Type: GrantFiled: May 18, 2001Date of Patent: March 25, 2003Assignee: TRW Automotive Safety Systems GmbH & Co.

Publication number: 20030054933Abstract: 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: ApplicationFiled: September 13, 2002Publication date: March 20, 2003Applicant: TRW Automotive Safety Systems GmbH & Co.
