Abstract
A leaf spring includes a plate having a thickness of between approximately 5 mm and 20 mm, a width of between approximately 20 mm and 200 mm, and a given length. The plate is arcuately deformed so that it includes a central portion with a height of between 20 mm and 40 mm. The plate exhibits a predetermined resiliency for maintaining the plate in a substantially horizontal position under a load of between 5 kg and 30 kg and for preventing the plate from breaking under a load of between 50 kg and 100 kg. Further, the plate includes first and second layers made of glass-fiber or carbon-fiber and a core member made of a polyurethane foam material positioned between the first and second layers.
