Abstract
A seat belt retractor includes a spool, a single spring adapted to impart a rotational force to the spool to wind the seat belt onto the spool, and a mechanism to cause the spring to apply to the spool a first force, which is a relatively high force, only during the initial stages of extraction of the seat belt from the spool and during the final stages of retraction of seat belt onto the spool, and to apply a second lower force to the spool during the remaining part of the cycle of operation of the spool.
