A webbing retractor includes: a take-up shaft on which a webbing that is applied to a vehicle occupant can be taken-up, and on which the webbing is taken-up due to the take-up shaft being rotated in a take-up direction, and that is rotated in a pull-out direction due to the webbing being pulled-out; a restricting member that, by being operated, restricts rotation of the take-up shaft in the pull-out direction; a sensing section that senses a pulled-out state of the webbing; and a control section that, in a case in which the sensed pulled-out state corresponds to a state in which the webbing is pulled-out to a predetermined position, operates the restricting member and restricts rotation of the take-up shaft.

Variable behaviour control mechanism with a variety of motion characteristics, the mechanism comprising means to measure a plurality of motion characteristics and to activate systems when a threshold of the motion characteristics is reached. The mechanism described is, for example, a vehicle seat belt and the mechanism minimises or prevents unwanted activation of line extension or retraction of the seat belt. A first mechanism is described where activation occurs between at least one primary system and at least one secondary system when a combination of the sensed motion characteristics achieves a threshold. A second mechanism is described where activation occurs between at least one primary system and at least one secondary system when at least one sensed motion characteristic achieves a threshold, the threshold being modified based on at least one further motion characteristic. A method of use of the above mechanisms is also described.

A webbing retractor includes a spool, a motor, a force limiter mechanism, a first rotating body, a second rotating body, a ratchet gear, a pawl body and a control section. The ratchet gear is provided at one of the first rotating body or the second rotating body. The pawl body is provided at another of the first rotating body or the second rotating body. The pawl body can engage with the ratchet gear in a case in which the first rotating body rotates toward one side, and engagement of the pawl body with the ratchet gear being cancelled in a case in which the first rotating body rotates toward another side. The control section drives the motor to rotate in reverse, such that the first rotating body rotates toward another side in a case in which a physical amount relating to load of the passenger exceeds a predetermined value during forward rotational driving.
