Definitions

  • the invention relates to a fastening component for fastening an airbag to a vehicle structure, as well as an airbag module and a vehicle.
  • Gas bags in particular side gas bags, are very well known from modern occupant restraint systems.
  • Side gas bags are fastened, for example, to the roof rail of a vehicle by means of straps.
  • straps In the straps there are fastening holes through which screws or other fastening means are guided in order to fasten the gas bag to the roof pillar.
  • Mounting holes can lead.
  • the tabs are usually made of multiple layers and can also be reinforced by sewing around them or additional seams, which, however, increase the manufacturing effort and the manufacturing costs. It is therefore the object of the invention to provide a fastening component, a gas bag module and a vehicle in which there is no damage to the fastening holes and which are nevertheless easy and inexpensive to manufacture.
  • a fastening component for fastening a gas bag to a vehicle structure, with a holding section, a first fastening section, a second fastening section and a reinforcing section.
  • the holding section limits a receiving area for the gas bag and connects the first fastening section to the second fastening section.
  • the first fastening section and the second fastening section lie opposite one another at a distance, the reinforcing section extending into the distance between the first fastening section and the second fastening section in the longitudinal direction.
  • the flap can be reinforced by the reinforcement section.
  • the fastening component on which the reinforcement section is provided fulfills other tasks, such as holding the gas bag in the assembled state, so that only one component is necessary for fastening the gas bag to the vehicle structure.
  • the longitudinal direction is the longitudinal direction of the receiving area, which essentially corresponds to the longitudinal direction of the gas bag and the longitudinal direction of the vehicle.
  • the vertical and transverse directions also correspond to the vertical and transverse directions of the gas bag or of the vehicle.
