Abstract:
1. A seatbelt retractor comprising: a spool for winding a seatbelt, a locking mechanism connected to the spool and 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 the seatbelt through a passenger when the spool rotates in the seatbelt-withdrawing direction relative to the locking member in the emergency condition, a motor for generating power to rotate the spool, and a power transmission mechanism connected to the locking mechanism for transmitting the power of the motor to the spool through the power transmission mechanism, the locking member, and the energy-absorbing mechanism.
