Abstract
A switchable retractor system includes a retractor with a spool. The spool is rotatable in an extension direction for extending a web and in a retraction direction for retracting the web. A first clutch has an engaged state where the first clutch inhibits rotation of the spool in the extension direction and a disengaged state where the first clutch allows rotation of the spool in the extension direction. A release actuator actuates the first clutch into the disengaged state when actuated by a user to allow extension of the web. A second clutch has a locked state where the second clutch inhibits rotation of the spool in the retraction direction and an unlocked state where the second clutch allows rotation of the spool in the retraction direction. A tension actuator actuates the second clutch into the unlocked state when actuated to allow retraction of the web into the retractor.
