Arrangement for joining seat, in particular to be used in airplane, to rail, comprising operating and control lever

摘要

Two elements with mushroom-shaped lower areas (5a,5b) are inserted into matching openings (11) at the rail (1) on the floor in a first step. An operating lever (6) is moved around a first horizontal axis (14) causing a control lever (7) guided by a bolt (17) sliding along a curved slot (8) in the lower area of the first lever (6) to move anti-clockwise around a second axis (13). Two more locking elements (4a,4b) located at a plate (16) at the lower end of the operating lever (6) are inserted by the motion into complementary openings (11) at the rail (1).
