Patent number: 9428146Abstract: [Object] To cancel both a function of a vehicle sensor and a function of a webbing sensor at a predetermined condition while having a simple structure and a fewer number of parts. [Solution] When fully retracting a seat belt 4, a cam follower 22b abuts against a first cam portion 20a; accordingly, an actuator holding portion 23b urges an actuator 13b in a non-operable position and a function of a vehicle sensor 13 is canceled. When a large load is applied to the actuator holding portion 23b while in the above canceled state, the load is supported by the first cam portion 20a; accordingly, first and second levers 22 and 23 do not pivot and cancellation of the function of the vehicle sensor 13 is prevented from being canceled. Furthermore, when a lock claw 22c is separated from a ratchet tooth 17b, a ring gear 17 becomes rotatable and a function of a webbing sensor 12 is canceled.Type: GrantFiled: October 9, 2013Date of Patent: August 30, 2016Assignee: TAKATA CORPORATIONInventor: Kenji Osada
