Abstract: The invention provides a seat track fitting and a corresponding method to lock seats on a known hollow track. In one embodiment, the track is longitudinally provided with a plurality of symmetric circular-shaped openings of a diameter greater than the width of the slot opening comprises a main body mechanism and a shear plunger provided with a screw associated with an anti-loosening component, slidably arranged with respect to the main body mechanism.

Abstract: The seat track fitting and corresponding method to lock seats on a known hollow track being longitudinally provided with a plurality of symmetric circular-shaped openings (22) of a diameter greater than the width of the slot opening comprises a main body mechanism (11) and a shear plunger (8) provided with a screw (2) associated with an anti-loosening means, slidably arranged with respect to the main body mechanism (11) between a sliding position and a securing position; wherein the main body mechanism (11) comprises: an upper portion for installation of the track fitting to a seat; and a lower portion having a width fitting within the width of the track's slot and comprising fixed studs (15) arranged at the same intervals as the circular-shaped openings (22) in the track (20), where the studs (15) have dimensions falling within the diameter of the circular-shaped openings (22) and laterally protrude from the width of the lower portion, and where the studs (15) are intended to lie below the track section (23
