Document Type and Number:

Japanese Patent JP5922097

Kind Code:

B2

Abstract:

To provide a cushion member that can simplify the overall seat structure and can reduce the cost. A cushion member 1 includes an intermediate layer 10, and an upper layer 20 and a lower layer 30 stacked and fixed thereto. The cushion member 1 is fixed to a frame by bending an end part of the cushion member 1 so that the upper layer 20 comes to the front side and the lower layer 30 comes to the back side. The intermediate layer is subjected to shear force and the upper layer and the lower layer are subj ected to compressive and tensile stress. With the spring characteristic of the intermediate layer, the residual stress of the tension and compression is applied to the upper and lower layers from the intermediate layer. Thus, the cushion member can have the restoring property, the generation of creases during no load application can be reduced, and permanent setting is made less likely, and moreover, the stroke characteristic (compression characteristic) in the thickness direction is apparently increased.
