ABSTRACT:
The apparatus is adapted to relieve tension on a shoulder belt of a vehicle safety belt system. The apparatus includes a pressure sensing means; a locking member; an electric actuating means; and a biasing means. The pressure sensing means is disposed in the back portion of a seat. The locking member may be a clamp bar or a pawl adapted to engage a ratchet wheel. The electric actuating means may be a solenoid which is mechanically connected to the clamp bar or pawl and electrically connected to the pressure sensing means. The electric actuating means is adapted to actuate the locking member to its locking position. The locking member counteracts the rewind mechanism of the retractor and relieves tension on the shoulder belt.
