Abstract
A mechanism disposed between a frame structure and a base structure, the mechanism comprising a damper including a piston rod. The damper is mechanically connected between the frame structure and the base structure in a normal mode of operation. The damper enables a longitudinal and suspended upward and downward movement of the frame perpendicular to a plane. An energy-absorbing arrangement that includes a plastically deformable absorbing element. The plastically deformable absorbing element is adapted to plastically deform in response to stresses greater than a predetermined threshold stress along an axis perpendicular to the plane. A bar mechanically attached to the plastically deformable absorbing element and having an engagement portion.
