introduced into the cavity formed by the blow mold through an opening in the plug connection 112 or in the blow mold materials especially suitable for the blow molding of the plastic housing 12 are polyethylene pe and polypropylene pp if the rigidity of the plastic housing must satisfy more stringent requirements materials with embedded reinforcing filaments can be employed likewise the articles by w ast in the periodical u201c kunststoffe u201d vol 20 1990 pp 1333 1345 and vol 81 1991 no 1 pp 27 35 may be consulted regarding suitable materials and blow molding techniques fig2 shows three mounting points 121 at which the air bag control apparatus can be fastened to a car body the mounting points 121 are located on the periphery of the circuit board in the vicinity of the mounting points 121 the circuit board contains bores the plastic housing 12 has recesses corresponding to the bores and contact surfaces surrounding the recesses for fasteners such as screws or rivets for example fig3 shows the circuit board 11 embedded into the material of the plastic housing at a fastening point 121 in this manner after the electronic apparatus 1 is mounted impulses are transferred directly through the fastening points to the sensor disposed in the electronic apparatus 1 likewise natural vibrations of the circuit board 11 in the plastic housing 12 are reliably suppressed in addition.
