ABSTRACT:
An emergency release for a seat belt retractor, especially for use in passive seat belt systems, which includes a handle rotatable from a first position to a second position so as to move a contact surface into engagement with a ratchet tooth of a ratchet wheel when the vehicle is in an other than normal orientation. Rotation of the handle from its second to a third position rotates the ratchet wheel out of its engagement position. A contact member moves the pawl to its disengagement position and in one embodiment the pawl prevents the contact member from returning until the vehicle is in its normal orientation. In such embodiment, once the vehicle resumes its normal orientation, the contact member is automatically reset.
