ABSTRACT:
A selectively manually operable tension-relieving mechanism with memory is disclosed. The improved tension-relieving mechanism is nominally disengaged from the retractor spool assembly to allow frictionless operation thereof and is manually engageable. An actuator lever causes the mechanism to become engaged with a seat belt retractor by engagement of a pair of ratchet disks. A pawl and groove assembly then cause operation in a tensionless mode upon a subsequent slight belt protraction. A latch retains the actuator in an engaged condition until override by the occupant or substantial subsequent protraction. Orienting means restores the mechanism to its initial condition upon disengagement.
