Abstract
A backward-leaning-movement seat leg structure is provided for attaching a seat to the floor of a vehicle or an aircraft. The backward-leaning-movement seat leg structure comprises a framework having a front beam; a rear beam parallel to the front beam; and a plurality of spreaders perpendicularly connected to the front beam and the rear beam; a rear leg being substantially arcuate and comprising a first segment pivotally connected to the rear beam and a second segment pivotally attached to the floor; an energy absorber comprising a sleeve pivotally connected to the rear leg; and an inner bar extending out from the sleeve; a rotatable arm comprising a first end fixedly connected to the front beam; and a second end pivotally connected to the inner bar of the energy absorber; a front leg comprising a third end pivotally connected to the rotatable arm between the first end and the second end; and a fourth end pivotally attached to the floor; a first fuse pin inserted through the rotatable arm and the inner bar of the energy absorber to prevent the rotatable arm from rotating relative to the inner bar; and a second fuse pin inserted through the sleeve and the inner bar to prevent the inner bar from travelling relative to the sleeve.
