A motor vehicle seat with an integrated child seat comprises inflatable chambers that can be brought from a compressed air source. The child seat includes air chambers that are inflatable in multiple, e.g., three, stages, and which are fixed, e.g., adhesively bonded or stitched, to the surface of the motor vehicle seat.

Airbag cushion assemblies for aspirating ambient air and related assemblies, methods, and components. Some embodiments may comprise an aspirating airbag cushion assembly comprising an airbag cushion housing, an aspiration housing coupled to the airbag cushion housing and comprising an aspiration inlet configured to allow for receipt of ambient air into an airbag cushion, and an inflation module slidably coupled to the aspiration housing. The inflation module may comprise an inflator and one or more inflation tubes or other conduits fluidly coupled with the inflator and configured to deliver inflation gas from the inflator into the airbag cushion.

Airbag inflator system including a housing defining a flow passage leading into an interior of an airbag). A reverse flow valve is arranged at an inlet end region and selectively enables connection of the flow passage to ambient atmosphere dependent on a pressure differential on opposite sides of the reverse flow valve. A gas generator is arranged in connection with the housing. An activation system provides a signal to the gas generator to cause generation of gas. An aspirator is arranged between the reverse flow valve and the outlet end region and includes an inlet portion alongside the reverse flow valve and an aspiration portion partly separated from the inlet portion to define at least one opening in flow communication with the gas generator. The aspirator is preferably configured to generate gas flow in accordance with the Prandtl-Meyer effect.

Airbag cushion assemblies for aspirating ambient air to enhance inflation. Some embodiments may comprise an inflation module comprising an inflator and a plurality of inflation nozzles fluidly coupled with the inflator and configured to deliver inflation gas from the inflator into an airbag cushion. A housing coupled to the airbag cushion may comprise an aspiration inlet configured to allow for receipt of ambient air into the airbag cushion during inflation of the airbag cushion. The plurality of inflation nozzles may be configured to, upon actuation of the inflator, draw ambient air into the airbag cushion along with the inflation gas from the inflator. In some embodiments, a valve assembly may be positioned below the inflation nozzles and may be configured to automatically open upon actuation of the inflator and to automatically close during or following inflation of the airbag cushion.
