Abstract:
An air bag module includes an air bag and a container including spaced apart end walls. An elongated inflator extends between the end walls for discharging gas to inflate the air bag. A lug projects outwardly from an inflator end of the inflator and the lug engages one of the end walls of the container. First and second opposing spring tabs are included on the one end wall of the container. The spring tabs each include a retention end which are spaced apart from each other and define a retention opening therebetween which is narrower than the lug on the inflator end. Upon insertion of the lug into the retention opening, the lug engages the retention ends of the spring tabs and deflects the spring tabs such that the retention ends of the spring tabs each grip against the lug to cooperatively capture the lug between spring tabs and prevent removal of the inflator from the container.
Abstract:
This present invention provides variable deployment performance by controlling the quantity and fluid flow path of the inflator gas into or out of an air bag module according to the present invention. The air bag module includes a slide ring mechanism disposed about an inflator and adjacent at least a portion of a cushion retainer. The slide ring mechanism comprises an annular ring having openings formed therein, wherein during rotation of the slide mechanism, the openings of the annular ring align with openings formed in the cushion retainer to define a fluid flow path away from an air bag cushion for venting some of the inflator gas. Preferably, the annular ring is rotated by attaching a pair of tethers to the annular ring and to a rear surface of the air bag cushion. As the air bag cushion inflates and reaches a predetermined pressure, the tethers are pulled causing the slide ring to rotate so that the openings in the annular ring and cushion retainer align directing an amount of inflator gas away from the air bag cushion. The present invention thus provides a direct mechanical system for cushion pressure feedback to tailor the inflation.
Abstract:
A seat restraint tensioner for a seat restraint system in a vehicle includes a housing for operative connection to vehicle structure and a movable piston disposed in the housing. The seat restraint tensioner also includes a gas generator operatively connected to the housing for expelling a gas to move the piston. The piston includes a passageway extending therethrough to control a rate of stroke of the piston when the gas is generated to apply a force for pulling-down belt webbing of the seat restraint system.
Abstract:
An air bag module includes an air bag and an inflator being activatable to discharge inflator gas for inflating the air bag. The inflator has at least one discharge port through which inflator gas is discharged. A housing has a wall adjacent the discharge port of the inflator and includes at least one vent opening. The module also includes a movable member alignable with the vent opening. The movable member is movable relative to the vent opening for opening and closing the vent opening at a predetermined time during inflator activation to control the amount of inflator gas discharged into the air bag and the amount of inflator gas expelled out through the vent opening of the housing. A device is activatable during activation of the inflator to move the movable member relative to the vent opening at the predetermined time during inflator activation.
Abstract:
An airbag module includes a gas generator comprising at least one snap connection element and a gas generator holder for the gas generator which has a complementary snap connection element to the snap connection element of the gas generator, with the snap connection elements being formed such that the gas generator can be fixed to the gas generator holder by means of a snap connection.
Abstract:
This present invention provides a deformable air bag module for use in an instrument panel or door panel of a vehicle. The air bag module has a deformable housing with an inflator and an air bag cushion being disposed within the deformable housing. The module housing has a neck portion defining an opening formed at a first side, wherein the first side is coupled to the instrument panel. The instrument panel includes first and second instrument panel sections and the module housing is disposed about the first and second instrument panel sections so that deployment of the air bag cushion causes deformation of the module housing resulting in the first and second instrument panel sections separating and deployment of the air bag cushion therebetween. When a tear seam is used to define the first and second instrument panel sections, the present invention permits the tear seam to be formed thicker in size and more durable.

Abstract:
An air bag module in a vehicle includes an air bag having a thickened mouth portion. The air bag module further includes a housing for housing the air bag and including a tapered neck portion. The module further includes a self-locking retainer having outwardly tapered retainer walls that are sized and shaped for engagement with the tapered neck portion of the housing. The thickened mouth portion of the air bag is trapped below the retainer such that upon air bag deployment, the air bag forces the tapered retainer walls into increasing engagement with the tapered neck walls such that the retainer and air bag are securely locked onto the housing.
Abstract:
A driver air bag module is provided that is attachable to the steering wheel of an automotive vehicle and includes dual cylindrical inflators mounted to a base plate to which an air cushion enclosing cover is attached. The inflators are retained in recesses defined between an inflator retainer and the base plate which provide means for directing gas from the inflators into the air cushion. The assembly utilizes relatively inexpensive cylindrical inflators which may be operated together for maximum pressure inflation of the air cushion or singly for a lesser pressure inflation where operation of the air cushion at a lower pressure is desired.
Abstract:
A restraint cushion includes a generally quadrangular sheet of material having a central portion and four corner portions extending from the central portion. Each corner portion has a fold line adjacent the central portion and two free edges extending from the fold line and intersecting each other to form a point. A mounting portion extends from one of the corner portions. The mounting portion has a cushion opening therein for receiving inflator gas therethrough to inflate the air bag. The mounting portion has outer edges which are spaced apart from the cushion opening. The corner portions are folded about the fold lines in overlying relationship to the central portion and in mating relationship to corresponding outer edges of the mounting portions. Each of the corner portions has one of the free edges joined to one of the outer edges of the mounting portion and each of the free edges is spaced apart from the cushion opening. Thus, the mounting portion and cushion opening are not disrupted by the mating edges forming the cushion.
