An inflatable side airbag has an inflatable duct for the delivery of inflation gas. The inflatable duct of the inflatable side airbag provides for rapid deployment of a multi-chamber air bag while controlling the rate of inflation and the relative pressure of the chambers. The inflatable duct allows a single inflator to inflate a high pressure pelvis chamber and a lower pressure thorax chamber while preventing fluid communication between the two chambers upon completion of inflation.

An airbag assembly can include a stabilizer strap attached to an airbag, and the stabilizer strap can cooperate with a housing to prevent undesired rotation or skewing of the airbag during deployment. In some arrangements, a portion of the airbag is secured to the housing via an inflator.

Knee airbag assemblies and related methods

Heat shields are used to shield an airbag from hot gasses issuing from an inflator. The heat shields can be a piece of thin metal that is coupled to the airbag cushion or the inflator. The heat shield can be held in place by being attached or coupled to the airbag and/or the inflator.

Inflatable airbag assemblies with heat shields

An airbag assembly with a reduced-cost knee airbag cushion and internal tethers can be formed from a single rectangular panel of material so that there is very little material waste. A pleat can be formed in a rear face so that the combination of tethers and pleat help the cushion deploy with favorable characteristics and adopt an arced shape when inflated. The cushion can have apertures for inserting an inflator with mounting stems partially within the cushion so that the mounting stems can be used to couple the cushion to an airbag housing. The assembly can also have a bag strap formed from a single piece of fabric that can wrap around a rolled and/or folded cushion. The assembly can also have a stabilizer strap that can be coupled to the cushion and to the airbag housing so that during deployment, the cushion does not skew or twist.

An inflator assembly is disclosed for use in an automobile. The inflator assembly features a slide-on housing around an inflator.

Slide-on inflator housing

The present invention relates to a pelvic airbag. The pelvic airbag has a front panel and a rear panel that is attached to the front panel. The airbag is made of metal, plastic, or combinations of metal and plastic and is configured such that it may be retained in a vehicle door between the inner skin and the trim panel. The airbag is further constructed such that when it is in the uninflated configuration, the thickness of the airbag is between about 2 to about 25 millimeters. An attachment mechanism may also be attached to the airbag. The attachment mechanism is designed to attach the airbag to the vehicle door. Additionally, an inflator housing may be attached to the rear panel. The inflator housing houses an inflator that is designed to inflate the airbag in the event of an accident or crash.

Expandable pelvic side airbag

An airbag cushion and method of folding thereof are provided which utilize a series of pleated folds which unfold in sequence one after another when an inflating fluid flows into the airbag cushion. In the so folded airbag cushion, a series of folds is made wherein a successive fold is made generally perpendicular to the preceding fold.

Airbag cushion and method of folding thereof

The process comprises the steps of gripping top and bottom boundaries of the face portion of the main panel of the cushion and pulling it so that the front face portion is generally planar and the side panels extend generally outward from the canister. First and second folding combs move inward from the opposite sides of the cushion. From the front a third folding comb moves rearward. Plates of the combs interdigitate with portions of the cushion inbetween, thus creating accordion folds. Fourth and fifth folding combs move in from the sides and their plates interdigitate with the plates of the other three combs, tucking excess portions of the cushion inbetween the accordion folds already formed. The package thus formed is compressed and then moved into the canister. A dust cover is slid over the front of the canister.

Airbag cushion folding process

An airbag module having a cushion with a compression-deployed volume. The module includes an inflator which produces a quantity of inflation gas. This gas inflates only a first volume of the cushion, which is positioned to protect a first portion of a passenger's body. Compression of the first volume by the passenger forces the gas from the first volume into a second volume, to thus inflate the second volume. The second volume is positioned to protect a second portion of the passenger's body. The initial quantity of inflation gas is thus reused, reducing the amount of gas required. This in turn reduces the size and cost of the inflator. The module is preferred for side impact protection, and a fold arrangement suited to accurate deployment is provided. The folded cushion may be secured to the inflator by a frangible film wrap, eliminating the need for an exterior housing. The module is preferably mounted upon the side of the passenger seat back.

Airbag cushion having compression-deployed section

The present invention comprises a new and improved method and apparatus for packing an inflatable air bag cushion into a housing of an air bag module assembly of an occupant restraint system for a motor vehicle. After securing an inlet chute of the air bag cushion in the open end of the housing and placing the air bag on a flat support with a larger portion of the back wall thereof overlaying a small portion of the back wall with the front wall in between in a folded condition, a central portion of the air bag is clamped by a large blade and subsequently a first edge portion is folded over the central portion and a second opposite edge portion is folded over the first edge portion so that opposite edge fold lines extend outwardly just inside opposite ends of the housing. A rolling clamp is attached transversely across the folded air bag and the air bag is rolled-up on an axis moved toward the housing. An inverted channel element is placed over the rolled-up air bag from above and moves the air bag to a position at the open end of the housing. An outer wall of the channel element which in any upwardly retracted position causes the rolled-up bag to be inserted into the housing and a trailing end portion of the air bag is tucked into place in the housing with a tuck blade after the outer wall of the channel element is withdrawn upwardly.

An improved retainer rod for a passenger-side airbag is formed of two different plastics having different physical characteristics by a dual durometer extrusion process. The improved retainer rod has a cylindrical main body of a hard rigid plastic which can withstand bag deployment forces and a sheet-like flag of softer flexible plastic which can be sewn to the bag material.
