System for fastening seat in rail of tail of aircraft, has lining plates secured at support surfaces of base through spiral springs, and locking slide connected with support surface and displaceable with respect to rail
The system has a base (1) connected with a seat rest and comprising support surfaces (3, 4) on a top face of a rail. A locking slide (5) is connected with the support surface. The locking slide is displaceable between an installation position and a locking position of an aircraft seat with respect to the rail by a lever-shaped device (6) under control of a mechanical assembly. Lining plates (9, 10) are secured at the support surfaces through spiral springs (11-14). The lining plates are made of polyurethane.
