In the event of catastrophic damage leading to explosive decompression it should keep you from being sucked out into thin air. Like if the roof tears off like that one time. Or that Boeing thing. Or that other Boeing thing. Or that other other Boeing thing.
Or keep you from bouncing and hitting the ceiling in cases of extreme turbulence. Or yo help on cases of lower-speed crashes (cases where the plane goes into some nosedive are less likely), etc.
