Ultra light saddle structure, particularly for pedal-driven vehicles and process for making its support frame

摘要: An ultra light multilayer saddle structure, particularly for pedal-driven vehicles, comprising a support frame (2) optionally covered with resilient padding (3). The has first skin (6) and second (7), between which spacer core (8) is interposed. the (7) include at least one layer (9) of material (10) respectively, selected among those having predetermined density relatively high compressive shear strength. (11) third whose lower than that materials. adapted to keep skins (6, 7) spaced-apart, increase stiffness mechanical strength frame, while reducing overall weight thereof. A process making structure provided.
