ROTARY RECLINER

摘要

A rotary recliner for a vehicle seat having a pair of meshing gears rotating about a common pivot. Axially movable wedge segments are provided to bias an eccentric mounting of one of the gears to a position forcing the gears into tight engagement with one another to eliminate free play and avoid rattling and vibration of the recliner. The wedge segments are axially movable upon rotary motion of an operating cap to relieve the free play reduction and enable adjustment of the recliner. The wedge segments do not function as bearing surfaces of the recliner during recliner adjustment to avoid high friction forces which must be overcome to adjust the recliner.
