PROBLEM TO BE SOLVED: To solve the problem in which it is difficult to fasten a shoulder webbing instantaneously in emergency as, in the case of a seating person with a small physique, a gap formed between the shoulder webbing, a shoulder part of the seating person and a seat back is large.SOLUTION: A recess 20 is formed on a side part of a shoulder part of a seating person by cutting a front surface upper part 16F of a seat back, and locking means 30 is provided at the recess to which a shoulder webbing 18c1 can be locked. The locking means 30 is, for example, made to be a (second) buckle 18e2, and a second tongue (intermediate tongue) 18d2 which can be engaged with the buckle is mounted in the middle of the shoulder webbing. The shoulder webbing 18c1 is stretched across the seating person diagonally from the shoulder part of the seating person via locking by the second tongue 18d2, and the second buckle 18e2 inside the recess.
【課題】体格の小さな着座者の場合は、ショルダウェビング、着座者の肩口、シートバックの間に形成された隙間が大きく、緊急時にショルダウェビングを瞬時に引き締めることが難しい。【解決手段】シートバックの前面上部16Fを切り欠いて着座者の肩口の脇部に凹部20を形成し、ショルダウェビング18c1の係止可能な係止手段30を凹部に設ける。係止手段30はたとえば(第2の)バックル18e2とされ、バックルと係合可能な第2のタング(中間タング)18d2がショルダウェビングの中間に取り付けられている。ショルダウェビング18c1は、第2のタング18d2、凹部内の第2のバックル18e2による係止を経て、着座者の肩口から斜めに着座者に掛け渡される。【選択図】図1
