  • Patent number: 6454486
    Abstract: The invention relates to a device for the detachable fastening of a steering wheel on a steering shaft having an axis. The steering wheel has a hub provided with a through-bore arranged perpendicularly to the axis of the steering shaft and the through-bore intersects a groove arranged in the steering shaft. The device comprises a fastening member arranged in the through-bore. The fastening member has a bolt with a head and a shaft provided at least partially with an external thread and has a nut able to be screwed onto the shaft of the bolt. The nut is able to engage into the groove and the through-bore has two oppositely directed radial support surfaces arranged between the bolt head and the nut. One support surface is arranged on the bolt head side and the other support surface is arranged on the nut side. A spring element is provided which engages one of the bolt and the nut and exerts a force onto one of the bolt and the nut.

  • Patent number: 6431599
    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 with a centric opening as a transition to an indentation in the gas bag. The indentation is formed in that during inflation a center portion of the gas bag wall is prevented from freely moving and is restrained. A closure part is provided which encloses one of the indentation and the opening and engages the gas bag wall. A traction device is provided which is connected with the closure part. The traction device is attached such that due to a deployment of the gas bag a tensile force is exerted on the traction device and the tensile force is passed on to the closure part, and one of the indentation and the opening is at least partly closed.

  • Patent number: 6432033
    Abstract: A method of folding a side gas bag in a packet form having a gas bag consisting of a substantially rectangular fabric section having rounded corners, a connecting plate for connecting to a gas generator and having fastening bolts projecting through the fabric section includes the steps of folding the fabric section along a first fold edge to an approximately square shape with free edges; arranging the free edges one over the other; and connecting the free edges with each other to form the closed bag. During the folding, a free space i8s formed between two adjacent layers of the fabric sections for the insertion of a fold rule. Thereafter, the free space is widened by means of a fold rule and the remaining fabric material is then, by means of further fold rules externally engaging and inserted, folded in on both sides from a center of the free space several times in meandering from in layers parallel to the connecting plate.
