摘要:
An apparatus and method for charging fluids to elongated pressure containers, such as inflators for airbag passive restraint systems is described. The disclosed method and apparatus enables the container to be filled from the side rather than from the end. The charging of more than one fluid to different chambers in the container is also facilitated, either by enabling two charges to be conducted simultaneously, or by allowing the two charges to be conducted through a single fill port.
摘要:
An airbag inflator that includes a pyrotechnic material capable of producing a quantity of gas during deployment. The inflator also includes a filter. The filter may be an expanded metal filter that is wrapped about the pyrotechnic material. When this filter is wrapped about the pyrotechnic material, the filter forms a plurality of layers having holes that are a different size. This filter also includes a first set of barriers and a second set of barriers that are positioned exterior of the first set of barriers, the second set of barriers being offset from the first set of barriers. Gas passing through the filter will encounter the first set of barriers, be re-directed, encounter the second set of barriers, be re-directed, and then flow out of the filter.
摘要:
An inflator device for an inflatable restraint system. The inflator device includes a tubular body with a center discharge opening disposed in a center portion of reduced diameter. First and second end closures each join an initiator to a respective opposing end of the tubular body to define a sealed chamber. First and second generant housings are disposed within the sealed chamber, define generant chambers containing a supply of generant material and include a plurality of openings providing fluid communication between the generant chambers and the sealed chamber. Rupturable initiator seals are disposed between the initiators and a respective generant chamber. A supply of pressurized stored gas and the supply of generant material are disposed within the sealed chamber.

An airbag module may have an inflator, a cushion, and a housing that contains the inflator and the cushion. The housing has an outer wall formed of a flexible material and a bracket designed to be attached to a vehicle. During deployment, the cushion is expelled out of the housing through the bracket. The inflator remains in the housing and inflation gas is conveyed to the cushion through the housing. The inflator may be retained by flaps wrapped around the inflator and secured to a perpendicularly oriented diffuser of the inflator. Alternatively, the diffuser may extend through an orifice formed in a fabric wall within the housing, and retention portions of the outer wall may be wrapped around the opposite side of the inflator. The airbag module may be mounted in an instrument panel to provide front seat, passenger's side impact protection without requiring a rigid module housing.
摘要:
An inflator apparatus for inflating an inflatable device and a method are provided which utilize a burst disk arrangement which results in a sequential opening regime such as may desirably provide a form of the above-described S curve inflation performance behavior without necessitating the use of or reliance on mechanical opening devices such as projectiles or piston members.

A tethered knee bolster panel which is deployed rearward in the passenger compartment of an automotive vehicle during a crash to provide lower torso restraint. The knee bolster is an air bag system which propels the knee bolster panel rearward during deployment. The activated knee bolster allows automobile designers the flexibility to provide increased leg room in the vehicle while maintaining the same level of safety during a crash.
摘要:
An airbag module cover having downwardly extending sidewalls is mounted in the base of an airbag housing. The base has downwardly extending peripheral legs thereon having inner and outer walls forming a generally U- or V-shaped integral groove at the lower extremity thereof. The legs have locking tabs positioned above the grooves which tabs are adapted to protrude into or through the sidewalls of the cover. When the sidewalls of the cover are locked in the grooves of the legs, the inner and outer walls of the legs provide lateral support for the sidewalls for preventing separation of the cover sidewalls from the housing during airbag deployment.
摘要:
A membrane horn switch has a flexible thin front plate and a rigid thick back plate. The plates are coated with a conductive layer which are separated by dielectric material applied to either or both plates. The plates are attached together around their perimeters using a pressure sensitive adhesive. The switch is attached directly to an airbag cover, eliminating the need for external backing other than that which is provided by the rigid back plate of the switch.
