The present invention is intended to provide a seat belt system capable of reliably preventing inadvertent engagement even on the occurrence of erroneous insertion of a tongue plate. The seat belt system of the present invention is equipped with first and second buckle units (1) and (2) respectively comprising tongue plates (3) and (4), and buckle bodies (5) and (6). The buckle bodies (5) and (6) respectively include: frames (17A) and (17B); ejectors (20A) and (20B); hook members (18A) and (18B) making engagement with engagement holes (14A) and (14B) formed at the tongue plates (3) and (4); and release buttons (21A) and (21B). A distance (N) from an insertion front end to the engagement hole (14A) of the first tongue plate (3) is longer than a corresponding distance (P) at the second tongue plate (4). A distance (L) from an abutment part (47A) to a pushing part (48A) of the ejector (20A) of the first buckle body (5) is shorter than a corresponding distance (M) of the ejector (20A) of the second buckle body (6). The ejector (20A) of the first buckle body (5) has suppression-specific projections (61) for preventing the pivotal movement of the hook member (18A) in a direction for making engagement. |
