PROBLEM TO BE SOLVED: To provide a buckle detaching device which can secure retention of a passenger by means of a seat belt and, at the same time, can detach a buckle by an external operation when the buckle is held between a seat and a vehicle interior component and a tongue is difficult to detach.SOLUTION: A buckle detaching device includes: a buckle 25 and a stay member 26 which are arranged between a seat 7 and a vehicle interior component 19; a support structure part 42 which supports the stay member on a seat frame; and a detaching mechanism part 44 which detaches the buckle. Therein, the support structure part includes a support shaft 46 which is supported so as to permit insertion to the seat frame 13a and inserts the stay member into the edge part, a restraint part 53 which restrains the stay member to the support shaft and a restraint release part 55 which releases the restraint of the stay member in accordance with access of the buckle to the vehicle interior component upon lateral surface collision, and the detaching mechanism part has a pushing mechanism part 60 which pressurizes the support shaft to the seat side by external operation when collision occurs between the buckle and the vehicle interior component.
【課題】本発明は、シートベルトによる乗員の保持を確保しつつ、バックルがシートと車両内装部品間に挟まれ、タングが外し難い場合に、外部操作によりバックルが外せるようにしたバックル取外装置を提供する。【解決手段】本発明は、シート7と車両内装部品19間に配置されるバックル25およびステー部材26と、ステー部材をシートフレームに支持する支持構造部42と、バックルを取外す取外機構部44とを備え、支持構造部は、シートフレーム13aに挿通可能に支持され、端部にはステー部材が挿通される支持軸46と、ステー部材を支持軸に係止する係止部53と、側面衝突時、バックルが車両内装部品に接近するのに伴い、ステー部材の係止を解除する係止解除部55とを有し、取外機構部は、バックルと車両内装部品間が衝突した際に、外部操作により、支持軸をシート側へ押圧する押し機構部60を有するものとした。【選択図】図5
