ABSTRACT:
Swivel mechanism for a vehicle seat, for example, includes a lower support-attachable element and a superimposed seat-carrying element interconnected by a turntable providing for 360.degree. angular movement of the upper element about an upright axis, together with latch structure for selectively locking the upper element in plural modes in angular ranges within the 360.degree. range. The turntable structure is in the form of an annulus through which securing bolts or the like pass upwardly for receipt by a retainer atop the upper element, the latter having a circular opening therein coaxial with the turntable and through which the securing bolts also pass to provide a rugged connection between the elements for resisting forces tending to separate the elements.
