ABSTRACT:
A retractor for seat belt provided with an emergency locking mechanism is disclosed. The retractor comprises a webbing taking-up means, an inertia sensing means, a locking means and an operating means. The inertia sensing means directly senses by means of inertia a change in speed of vehicle when the change of vehicle speed exceeds a predetermined level. When the inertia sensing means senses such change of vehicle speed beyond the predetermined level, the locking means interlocked with the inertia sensing means is brought into operation to lock the pulling out of the webbing from the webbing take-up means. The operating means is movable between a first position in which it allows a free movement of the locking means and a second position in which it restrains the movement of the locking means. When there is no need for emergency locking, the operating means is held in its second position by an external order issued from the outside of the retractor.
