Abstract: An airbag cover can include a sidewall to couple the airbag cover with a housing of an airbag assembly. The airbag cover can further include a panel adjoined to the sidewall at a hinge, and the panel can cover at least a portion of an opening defined by the housing through which an airbag positioned in the housing is deployable when the airbag cover is coupled to the housing. The airbag cover can include one or more tear seams that are breakable by the airbag as the airbag is deployed to form at least a portion of the panel into a door that rotates about the hinge to permit egress of the airbag. The airbag cover can further include a stress-relief region in the sidewall that is laterally adjacent to the hinge, and the stress-relief region can flex as the door rotates about the hinge to inhibit the door from separating from the sidewall during deployment of the airbag.

Abstract: An inflator for a vehicle inflatable safety system comprising a housing configured to contain a gas generating material, an igniting assembly, and an activating assembly. The igniting assembly includes an actuator plate that is configured to ignite the gas generating material contained in the housing and backer plate. The backer plate is attached to the housing such that a seal is formed therebetween that is capable of substantially stopping the flow of the gas generated by the gas generating material in any direction other than the predetermined directions. The igniting assembly also comprises a booster cup, an ignition charge, and a percussion primer. The booster cup with a conical-shaped end surface with the percussion primer disposed therein proximate to the actuator plate for igniting the gas generating material. The actuator plate and the end surface of the booster cup are in contact only along the peripheral edges thereof.
