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 detachably supports the stay member on a seat frame 13; and a detaching mechanism part 44 which detaches the buckle. Therein, the support structure part includes a support shaft 46 of which one end side is supported so as to permit insertion to the seat frame and the other end side is inserted to the stay member, a restraint part 48 which restrains the stay member to the support shaft and a restraint release part 55 which releases the restraint of the restraint part in accordance with access of the buckle to the vehicle interior component due to sheet deformation upon lateral surface collision, and the detaching mechanism part has a drawer mechanism part 60 which draws out the support shaft to the vehicle interior component 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が確保されつつ、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13に取外し可能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、一端側がシートフレームに挿通可能に支持され、他端側がステー部材に挿通される支持軸46と、ステー部材を支持軸を係止する係止部48と、側面衝突時、シート変位によりバックルが車両内装部品に接近するのに伴い、係止部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が衝突した際に、外部操作により、支持軸を車両内装部品側へ引き出す引出し機構部60を有するものとした。【選択図】図5
