Abstract
A pretensioner for a vehicle occupant safety restraint has an outer casing that contains a gas generant. An igniter has igniter material disposed within an igniter housing. A pair of electrodes are connected to the igniter material. A grounding path connector link electrically connects the igniter housing to a grounding path. The connector link may be formed by springs connecting the outer case to the grounding electrode and an interference fit connecting the igniter housing to the outer case. The link forms a low resistance path to short circuit undesirable static charges in the unit that would otherwise tend to cause unintentional activation of the pretensioner.
