A seatbelt assembly for a vehicle includes a seatbelt and a base retractor coupled to the seatbelt and configured to allow the seatbelt to extend to a desired length. The base retractor includes a first end portion including a biasing device, a second end portion disposed opposite the first end portion and including a speed-based locking mechanism, and a third portion disposed between the first end portion and the second end portion and including a spindle coupled to the seatbelt. The seatbelt assembly also includes a pretensioner coupled to the base retractor and configured to tighten slack of the seatbelt to ensure proper position of the vehicle passenger. Additionally, the seatbelt assembly includes an electromagnet disposed within or adjacent to the base retractor and configured to enable adjustment of rotational resistance applied to the spindle based on vehicle passenger size.
