1. A seat fixing device for anchoring aircraft passenger seats to the floor of an aircraft, comprising:
at least one attachment rail that has, in a fixed state of an aircraft passenger seat, a top side facing the aircraft passenger seat, wherein the attachment rail is designed in the form of a hollow section, and is provided on the top side with a longitudinal channel having a longitudinal axis, wherein the longitudinal channel is limited by free section sides of the hollow section and has through openings expanding the free input cross-section of the longitudinal channel in a given grid measure; a locking element having at least one catch part, wherein said through openings are used for the passage of the at least one catch part and wherein the catch part can be brought into clamping contact with the section sides of the hollow section in a clamping movement of the respective catch part relative to the attachment rail and transverse to the longitudinal axis of the longitudinal channel; and an eccentric drive, which is part of the locking element, wherein the eccentric drive operates the clamping movement of the catch part; and an energy reservoir, which discharges oscillations or shocks into the respective attachment rail, compensates for tolerances and is clamped with the attachment rail, wherein the energy reservoir is formed by at least one spring, which is supported, on the one hand, on the eccentric drive, and on the other hand, on stationary parts. |
