Systems, vehicles, and methods for seatbelt assistance. A system may include a sensor. The sensor may be configured to detect a physical property of a user sitting on a seat. The system may further include a motor. The motor may be configured to extend a seatbelt part towards a body center of the user. The system may further include an electronic control unit (ECU). The ECU may be coupled to the sensor and the motor. The ECU may be configured to receive the detected physical property of the user. The ECU may be further configured to prompt the motor to extend the seatbelt part towards the body center of the user based on the detected physical property of the user.
