摘要： A retractor includes a spool configured to selectively wind and unwind the webbing, a lock base configured to operate in a free position and a locked position, a first energy absorbing member coupled to the spool and the lock base, and a second energy absorbing member coupled to the spool and the lock base. When the lock base is in the free position, the spool and lock base freely rotate together when a force is applied on the spool through the webbing. When the lock base is in the locked position and a force is applied on the spool through the webbing, rotation of the spool is permitted while rotation of the lock base is prevented, such that the first energy absorbing member absorbs a first energy and the second energy absorbing member is configured to absorb a second energy after a predetermined rotation of the spool.
