The primary purpose of a seatbelt is to keep passengers securely in their seats during a crash. In the event of a collision, seatbelts are designed to restrain the occupants of a vehicle, significantly reducing the risk of serious injury or death. They work by distributing the forces experienced in a crash across the stronger parts of the body and preventing passengers from being ejected from the vehicle. Through this protective function, seatbelts are a critical safety feature that enhances the overall effectiveness of vehicle safety systems, including airbags.

The other options address aspects that are not the main function of a seatbelt. While comfort or appearance may be considered in the context of vehicle design, they do not reflect the essential safety role that seatbelts play in protecting passengers during accidents.
