ABSTRACT:
A vehicle shoulder safety belt retractor includes a first ratchet wheel carrying reel which is biased in a belt retraction direction and an oppositely oriented second ratchet wheel is mounted on the first ratchet wheel. A first normally retracted pawl is associated with the first ratchet wheel and a mechanism responsive to either highly accelerated belt withdrawal or the excessive acceleration or tilting of the vehicle or both for advancing the first pawl to lock the reel against belt extraction in emergencies. A second pawl is advanced by energization of an actuating solenoid to engage the second ratchet wheel and brake the reel against belt retraction. The solenoid is connected to a source of current through a series connected pair of switches, one of which is closed with the application of the seat belt and the other being located in the seat back and which is closed by the seat occupant reclining against the seat back so that the shoulder belt pressure against the comfortably seated occupant is obviated.
