ABSTRACT:
An improved tension-relieving apparatus for a shoulder belt of a vehicle safety belt system includes: a housing, a shoulder belt support, a locking means, a force transmitting means and an actuating means. The housing has an approximately U-shape including a back wall and two sidewalls. The shoulder belt support extends between the sidewalls of the housing. The shoulder belt moves partially around the shoulder belt support as the shoulder belt is unwound from the retractor and rewound into the retractor. The locking means is disposed adjacent to the shoulder belt support. The locking means includes a clamp pivotably disposed within the housing and extending between the sidewalls of the housing. The clamp, in its locking position, prevents movement of the shoulder belt around the shoulder belt support. The force transmitting means is mounted in the housing adjacent to the locking means and moves the clamp between its locking position and its unlocking position. The clamp in its locking position removes tension on the shoulder belt produced by the rewind mechanism of the retractor. The actuating means is located in the vehicle and actuates the force transmitting means.
