Abstract: A seat belt adjuster is provided for holding the shoulder belt to the lap belt of an automotive seat belt at a fixed distance to create a compound angle of assent of the shoulder belt to prevent it from crossing the occupant's face or neck. The adjuster is an assembly of three components; a shoulder belt clip, lap belt locking buckle, and a tether. The shoulder belt clip is tethered to the lap belt locking buckle pulling the shoulder belt closer to the lap. The lap belt locking buckle can slide along the lap belt for adjustment and then be locked into position by closing the locking arm of the buckle.
