Abstract
Abstract A webbing guiding structure suitable for use in an automobile seat belt system includes a slide rail and a movable runner displaceable along the slide rail. The slide rail defines a slide surface for allowing the movable runner to run on the slide surface. The movable runner is provided with a slidable shoe at a position where the movable runner is brought into contact with the slide rail. A contact surface of the slidable shoe, which is brought into contact with the slide surface of the slide rail, and the slide surface are arranged at an angle relative to each other as viewed in a direction transverse to the slide rail.

Total Claims: 12
Claim 1
Independent Claim
144 words
In a webbing guiding structure for an automobile seat belt system, said structure including a slide rail and a movable runner displaceable along the slide rail, the improvement wherein the slide rail defines a slide surface for allowing the movable runner to run on the slide surface, the movable runner is provided with a slidable shoe having a contact surface which is brought into contact with the slide surface of the slide rail, the slidable shoe is received in the slide rail, the movable runner extends outwardly at a part thereof through a slot formed in the rail, and the slide surface extending from one of edges of the slot and the contact surface of the slidable shoe are formed in such a way that the interval between the slide surface and the contact surface increases as the distance from the edge becomes greater.
Claim 2
Dependent Claim
