A reel assembly with dual locking mechanisms for restraining a vehicle occupant by controlling the displacement of a length of webbing, the reel assembly comprising: a webbing shaft with a geared end plate, the webbing being wound about the webbing shaft, the end of the webbing being releasably secured to the occupant by way of a clasp, whereby displacement of the webbing is controlled by rotation of the webbing shaft; a pair of locking pawls pivotally secured to the geared end plate, each locking pawl having pivoted and unpivoted orientations, a calibration spring secured to each locking pawl, each of the calibration springs having a bias that functions to urge the pawls into the unpivoted orientation, the bias being overcome when the webbing shaft is rotated at a predetermined rate, whereby the pawls are moved to the pivoted orientation; a locking ring having a geared inner periphery and an outer surface with a ramp, the locking ring positioned around the geared end plate and being independently rotatable thereto, at least one locking pawl engaging the geared inner periphery of the locking ring when the pawls are in the pivoted orientation, whereby rotation of the webbing shaft causes the rotation of the locking ring; a locking bolt with an elongated cutout, the locking bolt positioned adjacent the webbing shaft and having engaged and disengaged positions, a spring biasing the locking bolt into the engaged position, a trigger and a sear operatively coupled to the locking bolt, with the sear maintaining the locking bolt in the disengaged position against the bias of the spring, the trigger adapted to engage the ramp on the outer surface of the locking ring whereby the sear is displaced so as to permit the locking bolt to move into the engaged position; characterised in that a locking dog that is pivotally secured adjacent the geared end plate and having a distal end that rides within the elongated cut out of the locking bolt, the elongated cut out preventing the locking dog from engaging the geared end plate when the locking bolt is in the disengaged position, the elongated cut out forcing the locking dog into engagement with the geared end plate when the locking bolt is in the engaged position, with the locking bolt in engagement with the geared end plate the webbing is prevented from being displaced from the webbing shaft; whereby rotation of the webbing shaft at a predetermined rate causes the locking pawls to move into the pivoted orientation and engage the locking ring to restrict the displacement of the webbing from the webbing shaft, and wherein continued displacement of the webbing causes the further rotation of the locking ring which, in turn, causes trigger to engage ramp, whereby sear is displaced and spring is permitted to move the locking bolt into the engaged position such that the locking dog engages the geared end plate to prevent further displacement of the webbing. a webbing shaft with a geared end plate, the webbing being wound about the webbing shaft, the end of the webbing being releasably secured to the occupant by way of a clasp, whereby displacement of the webbing is controlled by rotation of the webbing shaft;
