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).

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 igniter, a partition member that axially partitions a space in the inside of a housing into a gas generating agent accommodation chamber and a filter chamber, and a gas generating agent and a coil spring accommodated in the gas generating agent accommodation chamber. The coil spring is interposed between the partition member and the gas generating agent and fixes the gas generating agent while it keeps the gas generating agent away from the partition member. V1 represents a volume of the gas generating agent accommodation chamber and V2 represents a volume of a non-filled space which is a space where the gas generating agent is not arranged in the inside of the gas generating agent accommodation chamber as a result of arrangement of the coil spring, where V1 and V2 satisfy a condition of 0.05V2/V10.32.
