Abstract
A seat belt retractor has a lock cup mounted for pivotal or rotational movement in relation to a bush mechanism over a predetermined arc of a circle. The arc subtends an active working section of less than 360.degree.. A wedge extends into the gap between the lock cup and the bush mechanism to reduce the gap when the retractor is at rest. Preferably a wedge extends from both the lock cup and the bush mechanism. Such an arrangement reduces the slack between the lock cup and bush mechanism without jamming the mechanism.
