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.

A swivel seat comprising: a stationary component secured to a floor; a pivotal component supporting a seat cushion for rotation therewith and pivotably supported directly above said stationary component, said pivotal component being pivotable between a first normal position and second pivoted position displaced by a predetermined angle from said first position; latching means for restricting movement of said pivotal component away from said stationary component at said first normal position of said pivotal component, said latching means including a first member secured to said stationary component, and a second member secured to said pivotal component and engageable to said first member at least at said first normal position; and a third member secured to said stationary component and having a first surface and a fourth member secured to said pivotal component and having a second surface, said first surface coming into contact with said second surface so that said third and fourth members restrict downward displacement of said pivotal component toward said stationary component, due to a load on said pivotal component, said third and fourth members cooperating with each other to raise said pivotal component to a predetermined highest position and cooperating with said latching means to restrict deformation of said pivotal component so as to maintain said pivotal component substantially in parallel to said stationary component at least at said first normal position.
