Abstract
Abstract A seat belt drawing angle adjusting device provided on the upper end part of a seat back, comprising a housing, a seat belt retractor supported within the housing, a seat belt guide member rotatably supported in the housing and a lock mechanism for locking and unlocking the guide member. The guide member has, formed therein, a slit through which a seat belt passes from the retractor to the outside, and is so arranged as to be vertically movable, thereby allowing vertical displacement of the slit. Hence, the seat belt can be adjusted at lower or higher level in relation to its drawing point.
