ABSTRACT:
A swivel seat for a vehicle is provided with latch means which prevents the front and rear edges of the seat from being raised so as to prevent distortion of the pivot axle, the locking means and/or roller or rollers. The latch means can be actuated to its effective position, in which it prevents lift of the front or rear edge of the seat when the seat is in its normal position. Preferably, the seat also has means cooperating with rollers and a pivot axle for supporting components rotatable relative to the stationary component. The supporting means serves to hold the movable component essentially parallel to the stationary component so as to reduce the load on the rollers and the pivot axle while allowing smooth pivotal movement of the movable component relative to the stationary component.
