Patent ID: 7652868

Claim:
Electropyrotechnic initiator comprising: a cap enclosing a pyrotechnic charge, an insulating printed circuit board comprising a first face on which there is a resistance element for heating the pyrotechnic charge, covered by the latter, and a second face opposite the first face, a first electrode and a second electrode for powering the resistance heating element, a support of the second face of the insulating printed circuit board, this support closing the cap and comprising an insulating structure through which the two electrodes pass, wherein the initiator also comprises means of protection against the electrostatic discharges, whose first terminal is connected to the first electrode and whose second terminal is connected to the second electrode, the means of protection against the electrostatic discharges are attached to the second face and are situated at least partially in the zone lying between the first electrode and second electrode, a recess of predetermined shape for housing the means of protection against the electrostatic discharges is made in the insulating structure extending between the first electrode and the second electrode and around the electrodes.
