Abstract
A belt retraction mechanism (200) including a biased spool (210) having a belt (300) wound thereon, the spool (210) biased to retract the belt (300), a pawl and ratchet mechanism for preventing rotation of the spool (210) in a direction of retraction, a biased cam member having an engagement surface, the cam member biased to an engagement position wherein the engagement surface engages the belt (300) thereby preventing movement of the belt (300) and moveable to an open position, and an actuator (240) moveable between an open setting and a closed setting, wherein the actuator (240) is manually operable to the open setting to release the pawl and ratchet mechanism and furthermore cause the cam member to move from the engagement position to the open position, thereby allowing the belt (300) to be moveable.
Claims12
A belt retraction mechanism including:
- a spool having a belt wound thereon for movement in a biased retracting direction and an opposite extending direction;
- a pawl and ratchet mechanism mounted for selective engagement with the spool for preventing rotation of the spool in the retracting direction;
- a cam member biased to an engagement position wherein an engagement surface of the cam member engages the belt, thereby preventing movement of the belt;
- and
- an actuator moveable between an open setting and a closed setting, wherein the actuator is manually operable to the open setting to release the pawl and ratchet mechanism to thereby cause the cam member to move from the engagement position to an open position, allowing the belt to move in the retracting direction.
