Picard sits in his command chair with the newly installed seatbelts
A seatbelt is a harness designed to hold and protect a passenger of a vehicle in case of an accident or a sudden stop.
Constitution class starship were equipped with seatbelts, which were employed in cases when there was a loss of gravity on the bridge. (TAS: "Once Upon a Planet")
Starfleet type-15 shuttlepods were equipped with seatbelts for all passengers. (TNG: "Power Play")
- A deleted scene from Star Trek Nemesis had the Enterprise-E's command chair being refitted with seatbelts. Captain Picard was delightfully surprised at the upgrade, noting "It's about time."
