Abstract:
A housing for an airbag module that contains an inflatable airbag cushion in a compacted configuration before being inflated by inflation gas supplied by an inflator device. The housing includes a collar for attaching the housing to a vehicle and a chute assembly formed of a flexible material and secured to the collar.
Abstract:
A passenger airbag assembly having a first cushion and a second cushion is disclosed. An inflator mechanism that independently inflates the first cushion and the second cushion may also be added. The inflator mechanism may either be a dual stage inflator or two separate inflators. Preferably, the airbag assembly is designed such that the inflator mechanism begins the inflation of the first cushion prior to beginning the inflation of the second cushion. A housing may also be added to the airbag assembly. The housing encloses the inflator mechanism and is attached to the first cushion and the second cushion. The airbag assembly may be designed such that when the first cushion and the second cushion are inflated, the second cushion is positioned between the first cushion and the vehicle's windshield. Furthermore, the airbag assembly may also be made such that when the first cushion is inflated, the first cushion will push a vehicle occupant towards the vehicle's passenger seat.
Abstract:
An airbag cushion is disclosed for use in automotive protective systems. The airbag cushion includes a tube that may be restricted to prevent gas venting. A cord is coupled to the tube and to a surface of the cushion. Upon airbag deployment, the cord extends until taut or extends until the cushion encounters an obstruction. If pulled taut, the cord tightens the tube and restricts gas venting. If the cushion encounters an obstruction, the cord remains lax and the tube is able to vent gas.
Abstract:
An airbag module may include an inflator (42), a cushion (40), and a deflection hood (44). When used as a passenger side, frontal impact module, the cushion deploys upward from a vehicle instrument panel. The deflection hood directs gas downward through a discharge opening and into the cushion to expedite inflation of the lower portion (62) of the cushion to more uniformly cushion a vehicle occupant's body. The discharge opening may be sewn shut via a tear seam to ensure that the discharge opening is properly positioned when the tear seam opens to release inflation gas. Alternatively, the discharge opening may be sewn shut by a non-tearable seam, and perforations may be applied proximate the non-tearable seam so that the discharge opening opens along the perforations to release the inflation gas. According to one alternative, the deflection hood may be angled within the cushion to provide a significant asymmetrical, lateral gas flow.
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 extruded protective cover (10) for holding a folded airbag (32) into an airbag module housing. The cover (10) includes two panels (14, 18) confronting edges of which each define one of a male connector member (20) and a female connector (16) which can be locked together with calliper tongs. The female connector member (16) has a deflectable guide shelf and a locking lip between which a slot is formed into which a locking edge of the male connector member (20) is inserted. Confronting hooks on the locking lip and the locking edge and outward pressure exerted by the airbag (32) on the guide shelf hold the locking members in engagement until airbag deployment occurs.
Abstract:
A relatively thin sheet is mounted between the door and the housing defining elongated corrugations spanning the open mouth of the housing and crushable against the edges of the housing to absorb energy and protect an occupant upon impact with the door. The corrugations are parallel and the sheet is attached to the door along attachment regions intermediate the corrugations. The corrugations are triangular in cross section. The door comprises a sheet metal substrate forming a rear surface facing the housing and a decorative surface forming a portion of the instrument panel and where the corrugated sheet is attached to the substrate.
Abstract:
The airbag module comprises a reaction canister in the form of a trough with an open mouth for deployment of an airbag. A cylindrical inflator is longitudinally positioned within the trough of the canister between the end walls, one end of the inflator being a gas diffusing end, the gas diffusing end oriented towards the first end wall, the other end of the inflator being oriented towards the second end wall. An end cap has a centrally located orifice, the orifice being fixedly attached to the diffusing end of the inflator, the end cap abutting an inner surface of the first end wall. A module diffuser housing encircles the inflator lengthwise along the canister, and is releasably, lockably secured to the end cap and fixedly secured to the reaction canister. An inflatable airbag positioned in the reaction canister to receive inflation gas from the inflator. The inflator is a hybrid inflator.
