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.
