Aircraft seat apparatus

An aircraft seat apparatus installed in a cabin of an aircraft, comprising:

• a plurality of seats arranged in said cabin to be adjacent to each other;
• and
• position adjusting means, formed between seat tracks and leg members of each of said seats, for adjusting a mounting position of said leg member of each of said seats in a direction intersecting an extending direction of said seat tracks, said seat tracks constituting said cabin floor member, extending on a cabin floor surface in a longitudinal direction of a fuselage, and arranged side by side to be separated from each other in a direction intersecting the longitudinal direction,
• each of said seats including
• a seat portion movable in a back-and-forth direction,
• a slide mechanism supporting said seat portion to be movable in the back-and-forth direction,
• said leg member supporting said slide mechanism to form a space under said seat portion together with said seat portion and fixed to a cabin floor member, and
• a seat portion driving unit arranged under said seat portion to move said seat portion in the back-and-forth direction, and
• said position adjusting means including a plurality of pipes extending to intersect the back-and-forth direction, arranged in the back-and-forth direction to be parallel to each other, and fixed to said plurality of seat tracks to intersect said plurality of seat tracks, and mounting means for adjustably mounting said leg member to said pipes.

• a slide mechanism supporting said seat portion to be movable in a back-and-forth direction;
• a leg member supporting said slide mechanism together with said seat portion and fixed to a cabin floor member of an aircraft;
• a seat portion driving unit arranged under said seat portion and making said seat portion move in the back-and-forth direction;
• a legrest installed to a front portion of a seat portion and arranged to be vertically pivotal about a rear end thereof as a fulcrum;
• a backrest having a lower end connected to said seat portion and inclined from a substantially upright state to a substantially horizontal state through a reclining state;
• and
• a backrest driving unit for inclining said backrest from a substantially upright state to a substantially horizontal state through a reclining state,
• wherein, said leg member has formed a predetermined size space between the portion under a seat portion and said cabin floor member.
