Abstract:
A frontal air bag system for a vehicle including an inflator mounted to vehicle structure and an air bag operatively connected to the inflator and mounted to a pillar of the vehicle. The frontal air bag system also includes a trim molding covering the air bag and mounted to the pillar. The air bag, inflated by the inflator, is extended downward and sideways in front of an occupant seated in the vehicle.
Abstract:
A tethering restraint system is provided which restrains an inflatable air bag cushion during an extended period of inflation rather than limiting such restraint to the final stages of inflation. Maintaining tethering restraint during the inflation cycle increases the time over which energy is transferred between the air bag cushion and an occupant to be protected thereby reducing the instantaneous force transferred between the occupant and the air bag cushion as contact takes place.
Abstract:
An inflatable safety restraint assembly is provided and methods are provided for installing such an inflatable safety restraint assembly into a vehicle. The inflatable safety restrain assembly comprises a cushion pack configured for attachment to an A-pillar of the vehicle and an inflator configured for attachment to a body structure of the vehicle other than the A-pillar. The inflatable safety restraint assembly further comprises a flexible tube having a first end connected to the cushion pack and a second end connected to the inflator. The flexible tube is adjustable to provide a number of orientations between the cushion pack attached to the A-pillar and the inflator attached to the vehicle body other than the A-pillar.
Abstract:
An airbag module is shown for an occupant restraint system of a motor vehicle. The airbag module has a housing in which a folded inflatable airbag is accommodated. A part of the housing is designed as a covering which is movable into the vehicle interior and which supports the knees of the occupant during the unfolding of the airbag. The airbag is designed in such a manner that it can be unfolded through an opening at the housing past the covering and into the vehicle interior when the covering is at least partly moved into the vehicle interior.
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:
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:
An inflatable knee bolster for a vehicle occupant is mounted in opposing relation to the knees of a vehicle occupant. The bolster is an expansible chamber of multipiece construction having a face portion and a separate three dimensional expansible body portion. The face portion and body portion are joined about their peripheries to define and substantially enclose the chamber. The expansible body portion is formed from injection molded polymeric material and has one or more integrally molded at least partially collapsible pleated profile elements disposed along the sides and across the top of the body portion in raised and lowered profile with respect to the face portion. Deformable mounting brackets extend outwardly from the body portion for attachment to the vehicle. The materials forming the face and body portions are of either similar or dissimilar chemical and physical character. Actuation of an inflator in fluid communication with the bolster pressurizes the expansible body causing at least a portion of the pleated profile elements to collapsibly deform such that the volume of the enclosed chamber is expanded and the face portion is thrust outwardly to an extended position.
Abstract:
A process of producing an aluminum alloy sheet product suitable for forming into automotive parts and exhibiting reduced roping effects. The process involves producing an aluminum alloy sheet product by direct chill casting an aluminum alloy to form a cast ingot, homogenizing the ingot, hot rolling the ingot to form and intermediate gauge product, cold rolling the intermediate gauge product to form a product of final gauge, and subjecting the final gauge product to a solutionizing treatment by heating the product to a solutionizing temperature, followed by a pre-aging step involving cooling the product to a coiling temperature above 50.degree. C., coiling the cooled product at the coiling temperature, and cooling the coiled final gauge product from the coiling temperature above 50.degree. C. to ambient temperature at a rate less than about 10.degree. C. per hour to improve T8X temper characteristics of the product. Additionally, a batch anneal step is carried out on the intermediate gauge product or at an intermediate stage of the cold rolling to reduce or eliminate roping tendencies of the alloy sheet product. To maintain a high T8X response, the alloy used in the process has the following composition: 0.4 to 1.1% by weight magnesium; 0.3 to 1.4% by weight silicon; 0 to 1.0% by weight copper; 0 to 0.4% by weight iron; 0 to 0.15% by weight manganese; 0 to 0.15% weight naturally-occurring impurities (collective total); and the balance aluminum. The invention also relates to a sheet alloy product exhibiting reduced roping effects produced by the indicated process.
Abstract:
The child resistant safety closure is one that uses a common single start thread on the neck of a container and on a closure. In conjunction with this single start thread there is a single mating projection on the neck and on the closure. These mating projections are in an interference fit until the closure is distorted so that the closure bows outwardly in the region of the projections whereby the projection on the neck and the projection on the closure can pass by one another. The distortion is enhanced by having the plastic of the closure in the area of the projection of a decreased thickness and the neck having flattened portions to provide for a easy distortion of the closure. By the use of a single start common thread and one projection the same closure can be used for containers requiring a safety closure and those not requiring a safety closure. The difference will solely be in the neck finish of the container or on the inner surface of the closure. When the container is to have a safety closure the neck finish has a projection to mate with a projection on the closure. In the instance where the container is not to have a child resistant safety closure either the closure will not have a projection or the neck of the container will not have a projection. In such a case the closure can be freely removed from the container.
Abstract:
An air bag module includes an inflator and an air bag for inflation upon the discharge of gas by the inflator. The module further includes a mounting and diffuser bracket for securing the inflator and air bag to the vehicle. The mounting and diffuser bracket includes a diffuser portion positioned radially outward of the discharge end of the inflator. The diffuser portion preferably includes wing portions substantially surrounding the discharge ports of the inflator such that upon discharge of gas by the inflator, the wing portions redirect and diffuse the discharging inflator gas into the air bag. Advantageously, the wing portions also provide a localized heat shield for the air bag.
