An adaptive load-limiting seatbelt assembly for a passenger vehicle includes a rotatable spool drum storing a length of seatbelt webbing and a piezoelectric device defining an interference fit between a pair of members of the piezoelectric device. The spool drum is operatively disconnected from the piezoelectric device during normal operation of the seatbelt assembly to permit free rotation of the spool drum and is operatively connected to the piezoelectric device during a dynamic event such as a vehicle crash so that the interference fit resists rotation of the spool drum in the pay-out direction to dynamically or statically control pay-out of the seatbelt webbing during the dynamic event.
