PROBLEM TO BE SOLVED: To improve the performance of constraining the upper body of an occupant at a support position, which is a high aimed position, of one end part in a seat width direction of a shoulder belt at the time of constraining the occupant.SOLUTION: A three-point type seat belt device S has a support part 50 of a tongue 40 which, in an attached state, supports one end part in a seat width direction of a lap belt 20L, and also supports one end part in a seat width direction of a shoulder belt 20S. A position where the one end part in the seat direction of the shoulder belt 20S is supported is a position away to an upper side of a seat from a position where the one end part in the seat width direction of the lap belt 20L is supported. In addition, the support part 50 has a lap side insertion 60L and a shoulder side insertion 60S, and is in an attached state where the lap side insertion 60L is inserted in a lap side buckle 70L connected to a member on the side of a seat cushion 12 and the shoulder side insertion 60S is inserted in a shoulder side buckle 70S connected to a member on the side of a seat back 14.SELECTED DRAWING: Figure 1
【課題】乗員拘束時のショルダベルトのシート幅方向一方側端部の支持位置を狙いの高い位置にして上半身に対する拘束性能を向上させる。【解決手段】3点式シートベルト装置Sでは、タング40の支持部50は、装着状態で、ラップベルト20Lのシート幅方向一方側端部を支持すると共にショルダベルト20Sのシート幅方向一方側端部を支持する。ショルダベルト20Sのシート幅方向一方側端部が支持される位置は、ラップベルト20Lのシート幅方向一方側端部が支持される位置よりもシート上側に離間した位置となる。また、支持部50はラップ側差込部60Lとショルダ側差込部60Sとを有しており、ラップ側差込部60Lがシートクッション12側の部材に連結されたラップ側バックル70Lに差し込まれ、ショルダ側差込部60Sがシートバック14側の部材に連結されたショルダ側バックル70Sに差し込まれて装着状態となる。【選択図】図1
