An air bag for a motor vehicle has catch straps which are located on the inside and by means of which an upper bag surface directed towards a vehicle occupant and a lower-lying bag surface of the unfolded air bag having an opening for a gas generator are held against one another along the length of the catch straps. By one end, the catch straps integrally adjoin a flat connecting part via which they are fixed on the upper bag surface by means of at least one connecting seam which runs around said connecting part and lies nearest to the catch straps, the connecting seam being disposed perpendicular to the pulling direction of said catch strap in the region of each catch-strap connection at least over the greatest part of the connection width.

The invention relates to an air bag for occupant restraint systems of motor vehicles, which air bag is automatically inflated by means of a gas generator in the event of an accident. In order subsequently to allow slackening of the air bag, a kidney-shaped or crescent shaped zone of the air bag cover, which is arranged at a greater distance from and approximately centrally to a central region of the air bag facing the occupant, is produced from gas-permeable fabric. Due to the specified shape and arrangement of this zone, the necessary load-bearing capacity of the air bag remains guaranteed.

A motor vehicle steering wheel has flat steel deformable spokes which connect a steering-wheel rim to a hub to be mounted on a steering shaft. The associated free ends of the spokes are cast into the cast hub, and each spoke has in the cast-in area a passage bore which extends in the axial direction of the steering wheel and penetrated by the hub material during the casting process. In order to achieve an increase in rigidity in the hub/spokes connecting area, the passage bore is arranged directly adjacent to the entry area of the spoke into the hub, forming a rolling step, such that in this area a tension-rod connection is formed between the hub material located above and below the spoke.
