SEATBELT DEVICE

摘要

A clutch (52) of a seatbelt device (10) has an urging member (45) for disengaging the clutch. When a pretensioner mechanism (15) is activated and an engagement section (49a) is moved in the direction of separating from a rotation member (50) by rotation of the rotation member (50) effected by the pretensioner mechanism (15), the urging member (45) is elastically deformed by the engagement member (49) to limit movement of the engagement member (49), and this disengages connection between an electric actuator (34) and a spindle (12). When the pretensioner mechanism (15) is activated, the connection between the spindle (12) for taking up a seatbelt and the electric actuator (34) is reliably disconnected. By this, an occupant is securely restrained when a pretensioner is activated.
