ABSTRACT:
A spring board is provided with an upper plate, a lower plate and interposed flanged profiles. For obtaining an optimal adaption of the spring board's shape to the local strains the local cross-section area of the flanges of the profiles varies along the length of said profiles. In a preferred embodiment of the invention the width of the flanges varies along the length of the profiles thereby producing a spring board having a constant parallel distance between the upper and lower plates and having the necessary varied moments of inertia along the spring board length.
