Patent ID: 8172193

Claim:
A seat track fitting to lock seats on an hollow track ( 20 ) of the type having an upper slot opening running along the whole upper surface of the hollow track, being the hollow track longitudinally provided with a plurality of symmetric circular-shaped openings ( 22 ) of a diameter greater than the width of the upper slot opening, said seat track fitting comprising: a main body mechanism ( 11 ) and a shear plunger ( 8 ) provided with a screw ( 2 ) coupled with an anti- loosening means or an anti-loosening component, 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 tightening the seat track fitting to a seat; and a lower portion having a width fitting within the width of the hollow track's upper slot opening and comprising fixed studs ( 15 ) arranged at the same intervals as the circular-shaped openings ( 22 ) in the hollow track ( 20 ), wherein the fixed 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 wherein the fixed studs ( 15 ) are made to lie below a track section ( 23 ) that define the upper slot opening; and the shear plunger ( 8 ) comprises: at least a couple of pins ( 16 ) staggered with respect to the fixed studs ( 15 ) of the main body mechanism ( 11 ); a screw ( 2 ) which acts parallel to the track by generating a friction between a sliding position and a securing position, and which upon tightening fixes the shear plunger ( 8 ) to the main body mechanism; and a conical notched bushing ( 4 ) co-axial to the screw ( 2 ) with anti-loosening features.
