ABSTRACT:
An airbag module utilizes tape dispensing cartridges. A tape end extends from each cartridge to the inside surface of an airbag. As the airbag inflates, tape is drawn from the tape cartridges as the tapes are drawn along with the deploying airbag. The rate at which tape is withdrawn from the cartridges is measured by sensible indicia of a magnetic or optical nature positioned on the tape and drawn past a sensor contained within the tape cartridge. The markings on the tape can be nonuniform along the length of the tape. The tape storage area outlet and the cartridge outlet are each formed by two relatively large radius corners. The tape is sealed to the cartridge to prevent the ingress of contaminants. As the airbag withdraws tape from the cartridges, the seals are unseated.
