Seat system having a canted leg assembly

In a seat system for a passenger aircraft wherein the seat system includes a passenger seat frame having (i) a plurality of spreader bars and (ii) a plurality of laterally extending spar tubes connecting said plurality of spreader bars to one another, the improvement comprising a canted leg assembly connected to said seat frame for attachment to fixed, spaced apart attachment points on a supporting surface of said passenger aircraft, said canted leg assembly offset a centerline about a floor tie and comprising:

• (a) a front leg portion including a front joint clamp for receiving one of said plurality of laterally extending spar tubes in a non-perpendicular attachment point;
• and
• (b) an aft leg portion including a non-perpendicular aft joint clamp for receiving another one of said plurality of laterally extending spar tubes in a non-perpendicular attachment point, wherein said front and aft joint clamps having annular collars that receive said spar tubes and said annular collars are canted thereby to cant said leg assembly;
• whereby said seat system is adapted to be laterally positioned and attached to provide different spaced apart passenger seating configurations.
