Claim 0:
1. A mounting system for a seat inside an aircraft, the aircraft having a first floor rail and a second floor rail, the first floor rail being spaced apart from the second floor rail, the mounting system comprising:
a first mount configured to follow and be mounted onto the first rail, an upper surface on the first mount including one or more upwardly-extending lugs, the lugs defining apertures therethrough;
a second mount being configured to follow and be mounted onto the second rail, an upper surface on the second mount including one or more upwardly-extending lugs, the lugs defining apertures therethrough;
a seat base configured to be secured onto and above the first and second mounts, the seat base including one or more downwardly-extending flanges, the one or more flanges including one or more apertures being alignable with the one or more apertures in the one or more lugs such that one or more bolts can be received through the flange and lug to secure the first and second mounts to the seat base;
each of the one or more bolts having a threaded end and a head, the head having a tool-receiving configuration; and
one or more inserts, each insert having:
an axially central bolt-receiving aperture;
a head-receiving side having a head-securing recess, the recess being configured to receive and secure the tool-receiving configuration of each bolt, thus causing each insert to rotate with each bolt;
an abutment side opposite the head-receiving side;
an outer edge of the insert comprising a substantially-arcuate shelf extending out from the abutment side of the insert, the arcuate shelf being configured to be rotatable inside a gap established between a lower end of each of the one or more downwardly-extending flanges on the seat base and an upper surface adjacent to each of the one or more lugs on the first and second mounts; and
the substantially-arcuate shelf having a plurality of varying thicknesses, each thickness in the plurality establishing a different compression level between the one or more lower ends of the flanges and the one on more upper surfaces adjacent to the flanges.
