ABSTRACT:
A seat belt retractor (10) includes a spool (100) on which belt webbing (16) is wound. The spool (100) is fixed for rotation with a shaft (110). The shaft (110) is acted upon by gravity with a first force. The seat belt webbing (16) provides a second force on the shaft acting counter to the first force. A means, such as a pair of M-shaped springs (130, 140), provides a biasing force on the shaft acting counter to the first force. The springs (130, 140) may also bias the spool (100) axially away from side walls (34, 36) of the retractor frame (30).
