Abstract
A seat belt retractor according to the present invention comprises a torsion bar 2 which is connected integrally with a bobbin 3 on one end side thereof and is connected integrally with a locking base 5 on the other end side thereof, a pawl 16 for preventing the rotation of the locking base 5 in the webbing pull-out direction thereof, a ratchet wheel 18 for bringing the pawl 16 into engagement with an engaging internal teeth 25 in a vehicle emergency, a control plate 65 which, in accordance with the winding amount of a webbing 50, positions a lock lever 55 at a first position in which the lock lever 55 is engaged with the ratchet wheel 18 and the pawl 16 is engaged with the engaging internal teeth 25 or at a second position in which the lock lever 55 is not engaged with the ratchet wheel 18, and a lock member 80 which, when the lock lever 55 is positioned at the first position, can be engaged with the ratchet teeth 3b of the bobbin 3 to thereby prevent the rotation of the bobbin 3 in the webbing pull-out direction thereof. Accordingly, it is possible to provide an improved seat belt retractor which can switch an energy absorbing mechanism between its operation condition and its non-operation condition by use of a simple structure.
