Can I go for "other"? My answer is "a world in which gravity, and therefore the effects of acceleration, can be adjusted, and therefore there is no point in having seat belts." Basically, if you get so little warning of a jolt that the anti-gravity mechanisms haven't time to kick in, then you don't have enough warning to fasten your seat belt.
This is fine for civilian ships; for armed ships that think there's a plausible threat of being shot at in the next few minutes, not so much. You just call it a "combat harness" instead of a "seatbelt", and procedure is that you can ignore it until the battle-stations call, at which point everyone straps in (unless their job actually requires them to move around).
