Abstract:
An inflator device for inflating an inflatable cushion of an inflatable cushion restraint system. The inflator device includes a supply of gas generant material disposed within a sealed chamber, and an initiator device in reaction initiation combination with the supply of gas generant material. A venting orifice connects the chamber to the surrounding ambient environment, and a rupturable seal seals the venting orifice. Upon reaction initiation of the gas generant material to produce inflation gas, the rupturable seal ruptures to vent the chamber to the ambient environment. A valve assembly can be disposed adjacent the venting orifice. A moveable valve piston, in combination with an actuator device, can block the venting orifice as needed to close the venting orifice and stop inflation gas venting. An optional tether release mechanism can be used in combination with the valve assembly to release a cushion tether upon closing of the venting orifice.
Abstract:
A method of joining tubular structures using friction welding is disclosed. The invention provides a method of joining a first tubular structure (11) having a conical contact surface (62) to a second tubular member (50) with an elliptical contact orifice by placing the conical surface within the contact orifice, rotating one of the structures, and pressing them together to form a weld. The invention further discloses airbag inflators constructed using the method of the invention.
Abstract:
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.
Abstract:
An improved adaptive output inflator is provided wherein inflator performance, such as measured by inflator gas output, can be appropriately varied and selected by appropriately varying and selecting the operational oxidant composition of the inflator.
Abstract:
compartimento flexível para um módulo de air-bag. trata-se de um módulo de air-bag (10) que pode possuir um dispositivo de inflação (42), uma bolsa de ar (40) e um compartimento (46) que contém o dispositivo de inflação (42) e a bolsa de ar (40) . o compartimento possui uma parede externa formada de um material flexível e um suporte angular projetado para ser ligado a um veículo. durante a aplicação, a bolsa de ar é expelida para fora do compartimento através do suporte angular. o dispositivo de inflação permanece no compartimento e o gás de enchimento é conduzido para a bolsa de ar através do compartimento. o dispositivo de inflação pode ser retido por abas envolvidas ao redor do dispositivo de inflação, e seguro junto a um difusor orientado de forma perpendicular do dispositivo de inflação. de forma alternativa, o difusor pode se estender através de um orifício formado em uma parede de tecido dentro do compartimento, e as partes de retenção da parede externa podem ser envolvidas ao redor do lado oposto do dispositivo de inflação. o módulo de air-bag pode ser montado em um painel de instrumentos para proporcionar proteção contra impacto no lado do passageiro no assento dianteiro sem requerer um compartimento de módulo rígido.
Abstract:
An inflator device for an inflatable restraint system. The inflator device (20) includes a tubular body (28) with a center discharge opening (42) disposed in a center portion of reduced diameter (40). First and second end closures (46,56) each join an initiator (48,58) to a respective opposing end (32,36) of the tubular body (28) to define a sealed chamber (26). First and second generant housings (70,90) are disposed within the sealed chamber (26), define generant chambers (82,102) containing a supply of generant material and include a plurality of openings providing fluid communication between the generant chambers (82,102) and the sealed chamber (26). Rupturable initiator seals (86,106) are disposed between the initiators (48,58) and a respective generant chamber (82,102). A supply of pressurized stored gas and the supply of generant material are disposed within the sealed chamber (26).

Abstract:
Un modulo de bolsa de aire (10) podria tener un inflador (42), un cojin (40), y un alojamiento (46) que contiene el inflador (42) y el cojin (40). El alojamiento tiene una pared exterior formada de un material flexible y una abrazadera disenada para que sea unida con un vehiculo. Durante el despliegue, el cojin es expelido fuera del alojamiento a traves de la abrazadera. El inflador permanece en el alojamiento y el gas de inflacion es llevado al cojin a traves del alojamiento. El inflador podria ser retenido por aletas envueltas alrededor del inflador y podria ser asegurado en un difusor perpendicularmente orientado del inflador. En forma alterna, el difusor podria extenderse a traves de un orificio formado en la pared de tejido dentro del alojamiento, y las porciones de retencion de la pared exterior podrian ser envueltas alrededor del lado opuesto del inflador. El modulo de bolsa de aire podria ser montado en el panel de instrumentos a fin de proporcionar proteccion contra el impacto en el lado del pasajero del asiento frontal sin requerir un alojamiento rigido de modulo.
