Abstract
A web locking retractor (20) for a vehicle safety restraint system is described comprising a spool assembly (60) mounted for linear movement with respect to a wedge housing frame (22) such that linear movement of the spool assembly (60), e.g. vertically, pushes against one or more clamping wedges (46a,b) to clamp a seat belt therebetween, characterized in that the spool assembly (60) is operatively coupled to the at least one clamping wedge (46a,b) via a resilient member, such as a coil spring (36a,b). The spool assembly (60) is operatively coupled to the at least one clamping wedge (46a,b) and this coupling is advantageously via a resilient member such as a coil spring (36a,b). Such a direct link between the clamping wedge (46a,b) and the spool assembly (60) provides for faster, more effective release of the clamping wedge (46a,b) from the belt when the loading on the belt diminishes below the spring bias force.
