Abstract: The invention relates to a gas bag module comprising a gas bag, an outer contour of the gas bag being defined by a gas bag wall which has a front wall for the impact of an occupant and an indentation starting from the front wall. The indentation is formed in that a center portion of the gas bag wall is prevented from freely moving during inflation and is restrained. The gas bag has a ring-shaped chamber to be filled with gas and extends around the indentation. Arranged in the indentation is at least one limiting strap which extends along the indentation and has an end pointing out of the indentation and, related to an inflated condition of the gas bag, is attached to the gas bag wall at least at the end pointing out of the indentation.

Abstract: A steering wheel unit for a motor vehicle, in particular a passenger car, comprises a connection hub which may be non-rotatably connected with a steering shaft of a steering device, a steering wheel rim which is non-rotatably connected with the connection hub by means of spokes, and a central piece which is mounted by means of a spacer element to the connection hub so as to be rotatable relative to the steering shaft and the steering wheel rim. The steering wheel unit further comprises a coupling device which arrests the central piece with respect to a rotational movement of the steering wheel rim. The spacer element has a first end which is non-rotatably connected with the central piece, and has a second other end which is rotatably mounted to the connection hub and constructed as a crash element. The crash element fails after a predetermined failure value of a force driving the central piece towards the connection hub.

Abstract: The invention relates to a passenger gas bag protection device which comprises a gas bag which, in relation to an inflated state, has a rear wall and a front wall which includes a center section and onto which a passenger strikes in the case of an accident. The gas bag, from a viewpoint of the passenger, has a round outer contour with a specific width and height in the inflated state. The width of the outer contour distinctly exceeds the height. In the inflated state the front wall has a depression opening out to the outside in the manner of a slit. The slit runs in a direction of the width of the gas bag. A restraint means is provided and the depression is formed in that on inflation of the gas bag a center section of the front wall is prevented from moving by means of the restraint means.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method of folding a gas bag for a vehicle occupant restraint system comprises the following steps: unfolding the gas bag between a base and a hold-down, a traction envelope extending around the gas bag and being passed through the hold-down at a first end, a first lead-through of the traction envelope through the hold-down being contoured so as to correspond to that required of the gas bag when folded; pulling out the traction envelope by means of the first end from a space between the base and the hold-down such that the gas bag is pushed together inside the traction envelope. There is further proposed a gas bag folded by such method.
