Abstract
A longitudinal locking mechanism in which a male lock member may be adjustably projected from a female lock member in the longitudinal direction thereof. The female lock member has a bellmouthed split end portion warped outwardly and radially relative to the central axis thereof. Such bellmouthed split end portion may be elastically closed by a slide ring for threaded engagement with the male lock member, so that a desired projection amount of the male lock member may be adjusted for locking purposes in a vehicle seat. The slide ring is biased in a direction to close the bellmouthed split end portion of female lock member, and may be drawn by an operation lever, via an actuation element, in a direction away from that bellmouthed split end portion so as to release the threaded enagement between the male and female lock members.
