An inflation assembly for use within a vehicle. The inflation assembly is configured to deliver gas from a pressure source to the one or more inflatable devices. The inflation assembly includes a fitting that engages with the pressure source and receives gas from the pressure source. The fitting includes outlet ports that are oriented to direct the gas away from the fitting and into hoses that lead to one or more inflatable devices. The outlet ports are configured to release gas in outward directions such that reactive forces that are applied to the fitting by the released gas are neutralized. This prevents the pressure source from moving and potentially injuring a person or damaging the vehicle.

The invention relates to a propellant cage (10) for a tubular inflator (100), especially for a tubular inflator (100) of an airbag module, for forming a propellant chamber (14) and a flow passage (15) of the tubular inflator (100). In accordance with the invention, the propellant cage (10) is in the form of a propellant cage spiral spring (11) having a gas inlet-side end (12) and a gas outlet-side end (13), the gas inlet-side end (12) having a smaller cross-section than the gas outlet-side end (13).

An airbag device includes a gas generator including a first gas generating agent and an ignition unit, and an airbag configured to inflate upon receiving a combustion gas from the gas generator, the airbag including an inlet being configured to cause the combustion gas supplied from the gas generator to flow into an internal space of the airbag, a bag-shaped portion configured to separate, from an outside, the internal space into which the combustion gas flows from the inlet, the bag-shaped portion being configured to be in a folded state and to be in an inflated state by receiving the supply of the combustion gas, and a second gas generating agent that is disposed at a predetermined position on an inner surface of the bag-shaped portion and generates gas by using thermal energy of the combustion gas without accompanying a combustion reaction.

A gas generator includes an elongated cylindrical housing, an accommodation chamber defining member arranged in the housing, a gas generating agent, and an autoignition agent. The accommodation chamber defining member includes a cylindrical portion which extends in a direction in parallel to an axial direction of the housing and accommodates the gas generating agent therein. A heat insulating layer is located between the housing and the cylindrical portion. The autoignition agent is arranged in a portion inside the housing in the axial direction of the housing where no heat insulating layer is provided, as being in contact with the housing with a member made of a metal being interposed.

The invention relates to a gas generator (10), in particular for a vehicle occupant protection system, comprising at least an igniter (15) and a combustion chamber (17) containing a pyrotechnic solid fuel bed (18), wherein a spring (30) is arranged in the combustion chamber (17), which spring can be elongated in the direction of an end (22) of the combustion chamber (17) remote from the igniter (16) by a gas flow produced when the gas generator (10) is activated. According to the invention, the spring (30) has a plurality of spring segments (31, 32, 33) having outside diameters (Q1, Q2, Q3) of different size

Disclosed is an inflation gas deflector for an automotive airbag assembly. The inflation gas deflector includes at least one layer of inorganic platelets or a multiple layer composite of at least one support layer and at least one inorganic platelet layer carried by the support layer. Also disclosed is an airbag cushion incorporating the inflation gas deflector and an automotive airbag assembly including the inflatable airbag cushion, the inflation gas deflector, and an inflator.

The invention relates to an inflator (10), especially for a vehicle safety system, comprising a combustion chamber (20) containing a pyrotechnical solid propellant bed (21). In accordance with the invention, an igniting mixture (25) is located in the combustion chamber (20), wherein a filler element (30, 30) is arranged to be movable between the igniting mixture (25) and the solid propellant bed (21) in the idle state of the inflator (10).

A gas generator includes a housing and a partition portion dividing a space in the housing into a combustion chamber accommodating a gas generating agent and a filter chamber accommodating a filter. The partition portion includes a first region which opens at the time of activation by being located to be opposed to a hollow portion of the filter and an annular second region which does not open even at the time of activation by being located to be opposed to a portion of an axial end surface of the filter except for the hollow portion. The second region is provided with a large-thickness portion constructed to be greater in thickness than the first region and opposed to an outer edge portion of the axial end surface of the filter, and the large-thickness portion is constructed to gradually be greater in thickness from an inner circumferential end portion toward an outer circumferential end portion.
