Fastening means for connecting aircraft or vehicle seats to supporting structure. For connecting aircraft or vehicle seats to supporting structure, there is provided means by which same can be accomplished quickly and easily and without the necessity for use of tools. A bar of rectangular cross section is positioned across the underside of single or multiple seats as desired. A tensioning screw extends upwardly through the base structure against a wedging spring which upon being tensioned tightly clamps interlocking flanges on the bar and base structure, respectively. A retractable pilot pin extends coaxially through said screw into a selected opening in said bar for positioning purposes. Thus, to readjust the spacing of the legs with respect to a given seating unit it is necessary only to retract the positioning pin, loosen the clamping screw and move the leg carrying base structure to a new desired position, reinsert the positioning pin and retighten the clamping screw, all of which can be carried out both quickly and manually. |
