Claim 18:
19. The apparatus of claim 18 wherein the apparatus is configured so that upon acceleration of the drum above a predetermined threshold value of acceleration, the pawl-support plate will rotate circumferentially rearwardly relative to the drum, causing the pawl to move circumferentially rearwardly relative to the drum and to the camming bollard, so that a radially-inward contact surface of the pawl and/or of the leading segment of the flexure arm impinges on a camming surface of the camming bollard causing the pawl to be urged bodily generally radially outward toward an engaged position in which an engaging end of the pawl engages a tooth of the ratchet.
