  • the airbag lies in a form-fitting manner on a surrounding vehicle interior contour, so that it is held in the desired position due to the form-fitting connection.
  • the form fit essentially corresponds to a “latching” because the inflated airbag is held securely on the vehicle structure.
  • the fabric layer facing a vehicle contour when the gas bag is inflated is longer than at least one other fabric layer facing away from the vehicle contour.
  • the gas bag has a step, so that the gas bag, when inflated, has two contact surfaces arranged essentially perpendicular to one another.
  • the contact surfaces can run at an acute or obtuse angle to one another, so that a pocket is formed.
  • the airbag is supported securely on the vehicle structure, in particular its, over a large total contact surface Vehicle contour, since two appropriately designed contact surfaces are provided. This ensures a large retention effect, since the gas bag can be supported over a large area, in particular on two mutually perpendicular surfaces due to the step.
  • the volume and the internal pressure in the gas bag can also be reduced because the gas bag has a high degree of rigidity when inflated. Accordingly, the load on the gas bag can be reduced.
  • a smaller gas generator can also be used to provide the inflation gas.
  • the gas bag due to the shape of the gas bag, in particular the stage which is present in the inflated state, it is possible to position the gas bag close to the vehicle occupant, so that the inflated gas bag can be placed against the vehicle occupant.

  • a small volume is advantageous in terms of the space required for the gas bag when folded and in terms of the available power of the gas generator.
  • the inflated gas bag forms a basis for the upper area of the gas bag, whereby the inherent rigidity of the upper area of the gas bag can be guaranteed.
  • At least one guy strap can be arranged in the interior of the gas bag, which is connected to the fabric layers forming the outer walls, so that in the inflated state of the gas bag at least two chambers are formed which extend at least in sections in the longitudinal direction of the gas bag.
  • the tensioning strap stabilizes the gas bag when inflated. In particular, arching of the gas bag is restricted by the guy band. This will increase the volume of the Gas bags limited, so that if necessary, sufficient rigidity of the gas bag can be achieved even with low internal pressure. In particular, a bending resistance moment is achieved which is suitable for adequately supporting a body of the vehicle occupant if necessary.
  • the longitudinal direction denotes the direction in which the gas bag has the greatest expansion in the inflated state. If the gas bag is arranged in a vehicle, the longitudinal direction can correspond to a vehicle vertical direction, that is to say essentially perpendicular to the plane in which the vehicle is moving.
  • the guy tape can be formed from a material that corresponds to the material of the fabric layers. This is advantageous with regard to the manufacturing process of the gas bag, since fewer different materials have to be provided and processed.

  • a constriction of the outer contour of the gas bag can be formed along the at least one guy band, in particular on both fabric layers.
  • a distribution of the air in the gas bag can be controlled, since when the gas bag is inflated, air is displaced in the region of the constriction and pressed into the surrounding areas of the gas bag, which areas can consequently exert a particularly good restraining force on an occupant.
  • At least two guy straps are provided which, in a side view of the gas bag in the inflated state, taper conically towards one another, in particular towards the head end.

  • the guy straps are arranged on the inside of the gas bag, whereby they are attached to both fabric layers. The guy straps are tensioned accordingly when the gas bag is inflated, so that they define the contour of the gas bag in the inflated state.
  • the fabric layers forming the outer walls are preferably sewn together in such a way that they form a substantially horizontal fold in the outer contour of the gas bag, via which the step of the gas bag is formed in the inflated state.
  • the gas bag is already in a folded state in a position that enables the gas bag to be applied to a vehicle structure in a planned manner shortly after the start of inflation, in particular on an edge of the vehicle structure that runs horizontally.

  • the fold and the darts are preferably assigned to different fabric layers of the gas bag. This prevents the darts from influencing the geometry of the fold and vice versa. Otherwise it could happen that the fold is distorted, as relatively high forces act on the surrounding tissue, especially in the area of the darts.
