A vehicle seat support includes a support tube mounted in the vehicle body for supporting the vehicle seats. The support tube is trapezoidal in cross-section and arranged with the wider of its parallel sides on top, facing the seats. The seats are mounted on support shackles having trapezoidal cut-outs corresponding to, and receiving, the tubular support member but being of somewhat greater height to provide some clearance. A thumbscrew is mounted in the seat structure above, and directed toward, the support tube for forcing the seat support shackle into firm engagement with the support tube.
