• a seatbelt assembly;
• a first sensor configured to detect a physical property of a user sitting on a seat, the physical property of the user including a body shape of the user;
• a second sensor configured to detect a position of the seat;
• a motor configured to move a part of the seatbelt assembly;
• and
• an electronic control unit (ECU) coupled to the first sensor, the second sensor, and the motor and configured to:
• receive first data relating to the detected physical property of the user,
• receive second data relating to the detected position of the seat, and
• command the motor to move the part towards a body center of the user based on the detected body shape of the user and the detected position of the seat.

A method for putting a seatbelt on a user, the method comprising:

• detecting, by a sensor, a physical property of the user sitting on a seat, the physical property of the user including a body shape of the user;
• receiving, by an electronic control unit (ECU) coupled to the sensor, data relating to the detected physical property of the user;
• and
• actuating, by the ECU, a motor to extend a seatbelt part towards a body center of the user based on the detected body shape of the user.
