ABSTRACT:
An automotive safety belt retractor comprising a remotely-operable, electromechanical tension-relieving system. The tension-relieving system is shifted into a tension-relieving mode by a conveniently located manual switch. Movement of the user to extract more than a predetermined length of belt while in the tensionless mode shifts the electromechanical actuator from an active to a released position. The electromechanical actuator is normally de-energized and is only energized momentarily when shifting between the tension-relieving and nontension-relieving modes. A second, automatic switch shifts the retractor out of tensionless mode upon opening of the vehicle door.
