Abstract: A roof airbag for a vehicle longitudinally extends along a length between first and second longitudinal ends and laterally extends along a width between first and second lateral sides. An inlet for receiving inflation gases is provided at the first longitudinal end. A plenum is in fluid communication with the inlet for receiving the inflation gases from the inlet. The roof airbag includes a plurality of primary inflatable chambers, each primary inflatable chamber in fluid communication with the plenum to receive inflation gases from the plenum. A plurality of secondary inflatable chambers is in indirect fluid communication with the plenum to receive inflation gases indirectly from the plenum through the plurality of primary inflatable chambers.

Abstract: A roof airbag arrangement includes an airbag, first and second guide rails, at least one first sliding member and at least one second sliding member. The airbag longitudinally extends along a length between first and second longitudinal sides and laterally extending along a width between first and second lateral sides. The first and second guide rails are on laterally opposite sides of the airbag, and define first and second channels, respectively. The at least one first sliding member is mounted within the first guide rail for translation within the first channel. The at least one second sliding member is mounted within the second guide rail for translation within the second channel. First and second pluralities of tethers connect the first lateral side of the airbag with the at least one first sliding member and the second lateral side of the airbag with the at least one second sliding member, respectively.

Abstract: A guide assembly for a roof airbag arrangement of a vehicle includes a guide member, at least a first sliding member and a locking member. The first sliding member is carried by the guide member and translatable relative to the guide member along a translation axis. The locking member is carried by the guide member and is operable in a first position to permit the first sliding member to translate past the locking member in a first direction and operable in a second position to prevent translation of the first sliding member past the locking member in a second direction. The second direction being opposite to the first direction.
