<p>PROBLEM TO BE SOLVED: To further effectively and certainly prevent a deviation of a seat belt caused by a rapid drawing out and a rapid winding of the seat belt at the time of emergency such as a collision of a vehicle. SOLUTION: The large number of projections are inclined and formed on a slide part 4b of the seat belt 3. An inclination angleθ1 of these projections is set to a larger angle than an inclination angleθb in an insertion direction to a guide hole 4a of the seat belt 3. Accordingly, when the seat belt 3 is rapidly wound by an operation of a pre-tensioner at the time of emergency such as the collision of the vehicle, it is inhibited that the seat belt 3 is moved to a vehicle front end side of a guide hole 4a by a reaction force caused by a friction from a vehicle rear side edge 5a of the projection 5. Thereby, a deviation of the seat belt 3 to a front side of the vehicle can be further effectively and certainly prevented at the time of rapid winding of the seat belt 3 caused by the operation of the pre-tensioner.</p> |
