Swivel Mechanism For Rotation Of A Seat In An Automotive Vehicle

A seat assembly includes a swivel mechanism for providing rotation of the seat assembly in an automotive vehicle. The swivel mechanism includes a first plate assembly coupled to a second plate assembly at a rolling-element bearing to facilitate axial rotation of one of the first and second plate assemblies relative to the other of the first and second plate assemblies. A lock plate slidably disposed on the second plate assembly selectively engages a lock pin extending from the first plate assembly for movement between a locked position in which the swivel mechanism cannot rotate and an unlocked position in which the swivel mechanism can freely rotate. Actuation of the lock plate between the locked position and the unlocked position actuates movement of a wedge between a cinched position to stabilize the swivel mechanism and an uncinched position to allow unimpeded rotation of the swivel mechanism.
