Abstract
A front leg (1) is formed by an upright support rod extending vertically above a fixing stud (8), a rear leg (2) is formed by both a lower support rod (2a) extending on a diagonal line joining the upper end of the front leg and the lower end of the rear leg and an upper support rod (2b) contiguous to the lower support rod (2a) in an upper position relative to the lower support rod, the upper support rod (2b) being curved arcuately and inclined rearwardly upwards, and an energy absorber (12) is mounted bridgewise as a diagonal member between the upper end portion of the front leg and the lower end portion of the rear leg, to constitute a leg structure. Accordingly to this leg structure, a striking energy is absorbed by an anti-plastic deformation force induced when the rear leg (2) and the energy absorber (12) is deformed plastically under an impact larger than a predetermined value, and the seat is held at its supported posture in normal use. This leg structure can be utilized not only in aircraft but also in automobiles and railway vehicles.
