Belt retractor with belt retraction lock

摘要

An automatic belt retractor mounted within a boot having belt retraction locking means mounted within the boot to lockingly but releasably engage the belt to counterbalance the spring bias retraction of the retractor spool. The belt locking means includes a base member with a tongue disposed toward the belt and a moveable member slideably received by the base member also with a tongue disposed toward the belt, the belt being disposed between the base and moveable members. Such members define a belt locking position when their respective tongues are aligned to arrest the belt therebetween, preventing the retractor from cinching up the belt upon repeated momentary loosenings of the tension upon the belt. Concurrently, such moveable member's rigid rod engages the retractor's rotatable cam plate and is operable to rotate such cam plate manually to lock the retractor during all times when the belt locking means are engaged. An external tongue protruding through the boot is operable to move the moveable member between belt locking and belt unlocking positions. Such external tongue can be disposed to exit on either the top or bottom of the boot.
