摘要

The support frame which was covered to option stuffing ones which have elasticity by (3) it possesses (2), the super lightweight multilayer saddle structure and the super lightweight multilayer saddle structure for the especially pedal drive vehicle. The aforementioned frame (2) has the first crust (6) and the second crust (7) with, at these time, the spacer heartwood (8) is arranged. The aforementioned first crust (6) and the second crust (7) with, respectively, has more the first material (9) with more the second material (10) with at least, these materials are selected from those which possess big compressed and shearing strength in specified density and ratio. The aforementioned heartwood (8), density the description above first and second is smaller than density of the material, more the third material (11) it possesses at least. Although the aforementioned heartwood (8), the crust (6 and 7) isolating arranging, it makes with the rigidity and mechanical strength increase of the aforementioned frame, makes the gross weight of the said frame decrease on the one hand it is suitable. The frame for the aforementioned saddle structure the method of producing (2) is offered. Selective figure Figure 1
