Abstract
A seat belt retractor comprises a spool or shaft onto which a seat belt may be retracted. A first relatively weak spring is provided which tends to wind the belt onto the spool or reel. A second stronger spring is also provided which tends to wind the belt onto the reel but the second spring is only activated selectively, for example when the buckle is released. Thus the strong spring does not, in normal circumstances, pull the belt tightly across the chest of a person wearing it.
