Abstract
A hinge mechanism for a vehicle seat comprises first and second cheek plates connected to each other via a hypocycloid gear driven by a first control shaft, and further comprising a third cheek plate which guides toothed slugs that are normally maintained in engagement with a set of teeth of the second cheek plate by a resiliently biased cam. In this way, the second and third cheek plates are normally secured to each other; however, by actuating a second control shaft secured to the cam, the slugs can be released, thereby enabling the third cheek plate to rotate freely relative to the second cheek plate, thereby enabling the seat to be adjusted quickly.
