Seat securing system

Seat securing system, especially for securing aircraft passenger seats to the floor of an aircraft, having at least one securing rail (10) designed as a hollow section which on its upper side (12) facing the aircraft passenger seat is provided with a longitudinal channel (14) which is bordered by the free section flanks (16) of the hollow section and which in the longitudinal direction of the securing rail (10) in a definable grid has through openings (18) which widen its free entry cross section and which are used for engagement of detent parts (22) of a base body (24) which are configured in succession in a row and are spaced apart from each other, the spacing of the detent parts (22) of the base body (24) being adapted to the spacing of the through openings (18), and when the detent parts (22) move in relative terms opposite the through openings (18) along the longitudinal axis of the securing rail (10) the detent parts (22) can be moved into contact with the section flanks (16) of the hollow section, and next to the base body (24) as an additional component there being a mounting part (26) for mounting on the securing rail (10), which part has other detent parts (30) for engagement with the assignable through openings (18), characterized in that in the relative motion between the mounting part (26) and the base body (24), they (24, 26) can be moved transversely to the longitudinal direction of the securing rail (10) into a fixing position and that in the fixing position a locking body (34) which is under the action of an energy storage device (32) and which can be pivoted from a release position into a locking position fixes the respective detent parts (22, 30) and accordingly the base body (24) and mounting part (26) on the securing rail (10).
