Definitions

  • the invention relates to a cover of an airbag firing channel with an airbag flap formed by the cover, which tears open on three sides by the triggered airbag cushion and pivots around the fourth side forming a hinge point, the airbag flap having a material web on the inside as a flap support wall that extends beyond the hinge point a wall of the firing channel extends on the inside.
  • the object of the invention is to improve a cover of the type mentioned at the outset in such a way that the material web has a firm, permanent connection with the airbag flap and the firing channel wall.
  • the material web has numerous openings which are penetrated by the plastic of the firing channel wall and / or the airbag flap in order to achieve a positive fit between the material web and the plastic of the firing channel wall.
  • the plastic melt penetrates the airbag flap and the firing channel wall through the openings in the material web, so that an inseparable, Positive connection is achieved, which cannot be released by the high forces of the airbag cushion acting on the airbag flap.
  • the openings are U-, L-, T- or double-T-shaped.
  • the form fit between the plastic and the material web is further increased if the edge of the openings in the material web protrudes from the surface of the material web to one side or to both sides.
  • a further improvement in the form fit is achieved if at least one projection, in particular a tongue, is formed on the edge of the openings in the material web and protrudes from the surface of the material web.
  • a further advantageous embodiment is provided when the end of the material web facing away from the airbag flap forms a fold, the fold line of which runs parallel to the axis of rotation of the hinge point and which is located within the plastic material of the firing channel wall, the fold line of the material web being interrupted by numerous openings that are opened by the Plastic of the firing channel wall are penetrated.
  • the openings in the fold line should be regularly arranged at equal intervals.
  • the function of the hinge point of enabling the airbag flap to pivot and thereby preventing the airbag flap from tearing off is improved by the fact that the material web forms a fold in the area of the hinge point. It is also proposed that the material web has a woven or knitted fabric made of polypropylene or polyester, which is covered on both sides by a thermoplastic composite material.
  • the airbag firing channel 1 surrounds an airbag cushion (not shown) with firing channel walls 5 and with at least one airbag flap 2 on the outside is covered by an outer cover 10, which has a foam layer and carries an outer skin, which tear open with.
  • One or two flaps 2, which cover the airbag cushion, are incorporated in the plate-shaped airbag cover in such a way that predetermined breaking lines 9 are arranged on three edges of each flap within the cover plate, which penetrate the entire plate and release the flap 2 after the airbag cushion has been triggered .
  • the airbag flap 2, together with the firing channel walls 5, is injection-molded from plastic, with a material web 4 lying in the injection mold, which is encapsulated by the plastic melt, so that the material web 4 lies within the plastic of a firing channel wall and the airbag flap 2 is close to the firing channel 1 .
  • the material web 4 runs through the hinge point 3 of the airbag flap.
  • the material web 4 has numerous openings 6 which are penetrated by the plastic of the firing channel wall 5 and / or the airbag flap 2 in order to achieve a positive fit between the material web and the plastic of the firing channel wall. These openings 6 are preferably also located in the area of the hinge point 3 of the material web.
  • the openings 6 can be U-, L-, T- or double-T-shaped and create a form fit that is further increased by
  • the openings 6 in the material web and in the fold line 8 of a fold 7 at the lower end of the material web 4 located in the firing channel wall 5 are preferably arranged at equal intervals.
  • the material web 4 has a woven or knitted fabric made of polypropylene or polyester, which is covered on both sides by a thermoplastic composite material.
