Claim 0:
1. A method of adjusting a seat bottom angle, the method comprising: with a seat comprising:
a seat frame;
a seat bottom slidingly and pivotally attached to the seat frame by an aft articulating mechanism and a forward articulating mechanism;
the aft articulating mechanism connected with the seat bottom near an aft end of the seat bottom and defining a first path that declines in an aft-to-forward direction to cause the aft end of the seat bottom to move downward by a first distance when the seat bottom is moved forward; and
the forward articulating mechanism connected with the seat bottom near a forward end of the seat bottom and defining a second path shaped to cause the forward end of the seat bottom to move upward by a second distance when the seat bottom is moved forward, the second distance being different from the first distance; and

a release mechanism operably connected with the seat bottom and with the seat frame;
with the seat bottom connected to the seat frame by the aft articulating mechanism and disconnected from the seat frame by the forward articulating mechanism, moving the seat bottom forward of a second seat position or aft of a first seat position to an install seat position whereby the forward articulating mechanism is receptive to engagement
engaging the forward articulating mechanism such that the seat bottom is connected with the seat frame by the forward articulating mechanism;
moving the seat bottom forward to the first seat position whereby the forward articulating mechanism constrains the seat bottom with respect to the seat frame;
connecting the release mechanism with the seat frame and the seat bottom such that the seat bottom is prevented by the release mechanism from returning to the install seat position from the first seat position;

actuating the release mechanism to free the seat bottom to move with respect to the seat frame;
moving the seat bottom forward from the first seat position to the second seat position such that the aft end of the seat bottom slides downward and forward along the first path, and the forward end of the seat bottom slides upward and forward along the second path, causing the seat bottom to tilt aft in the second seat position; and
disengaging the release mechanism to lock the seat bottom in the second seat position.
