Abstract
A seat structure with latching-unlatching mechanism for enabling smoothly operating releaseable locking and unlocking actions between a seat-base and an inclinable seat-back hinged to the seat-base in the seat structure. Two interengageable arcs of gear teeth forming part of the mechanism engage and release selectively under rocker-lever seat-occupant control to lock and unlock the seat-back for inclinational fixation and adjustment, and, as determined by tooth-pitch in the arcs, enable positive locking to take place in a large number of specific, small-angular-difference, seat-back inclinations.
