Abstract
A seatbelt retractor includes a spool for winding a seatbelt; a locking mechanism having a locking member rotatable together with the spool in a normal condition and being prevented from rotating in a seatbelt-withdrawing direction in an emergency condition; an energy-absorbing mechanism interposed between the spool and the locking member for absorbing shock energy exerted on a passenger when the spool rotates in the seatbelt-withdrawing direction relative to the locking member in the emergency condition; and a motor for generating power to rotate the spool. A power transmission mechanism is connected to the locking member for transmitting the power of the motor to the spool through the power transmission mechanism, the locking member, and the energy-absorbing mechanism.
