Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The invention as well as the technical environment are explained below by way of example with reference to the figures.

[0020] FIG. 1 shows schematically a perspective view of an airbag housing diagonally from the top,

[0021] FIG. 2 shows schematically another perspective view of the airbag housing diagonally from the bottom, and

[0022] FIG. 3 shows schematically the airbag housing in the view of FIG. 2 with a gas generator and a cover.

DETAILED DESCRIPTION

[0023] The figures show schematically an airbag housing 1 with opposing side walls 4, opposing end walls 5 and a bottom 3. Bottom 3, side walls 4 and end wall 5 confine a receiving space 2, in which a gas generator 13 and a gas bag can be arranged. In the assembled state, receiving space 2 is closed by a cover 12 (shown in FIG. 3) which is fastened to airbag housing 1 by fastening brackets formed on side walls 4.

[0024] Airbag housing 1 has two fastening sections 6 which project in the plane of floor 3 from end wall 5. Holes are formed in fastening sections 6, through which a fastener can be passed, so that airbag housing 1 can be fastened to a vehicle.

[0025] In end walls 5, recesses 8, which are completely surrounded by end wall 4, are formed in the form of openings, through which electrical connecting elements for gas generator 13 can be passed.

[0026] Bottom 3, side walls 4, end walls 5, and fastening portion 6 are integrally formed from a single blank of metal sheet 7. End walls 5 are each formed from two metal sheet sections 11, which, initially projected from side walls 4 and have been bent to form end walls 5, and were joined to one another.

[0027] In the area of end walls 5, a ribbing 9 is formed in bottom 3, which in each case extends starting from bottom 3 into a fastening section 6. In fastening section 6, ribbing 9 extends in sections transversely to longitudinal direction 10 of airbag housing 1. Ribbing 9 stabilizes the fastening section and the transition area in bottom 3 against bending.
