Abstract
The purpose of the present invention is to provide a cushioning material structure, for a vehicle seat, that makes it possible to reduce the weight of the vehicle seat while maintaining stable riding performance. A cushioning material supported by the top surface of a bottom plate provided on a vehicle body is provided with voids. This allows weight reduction without reducing the thickness of the cushioning material as in conventional cushioning-material structures, thereby making it possible to reduce the weight of the vehicle seat while maintaining stable riding performance.

A cushion material structure of a vehicle seat, comprising:
- a cushion material supported by an upper surface of a bottom plate that is provided on a vehicle body,
- wherein the cushion material is formed so as to bend at a lowest layer part thereof and not at an upper layer part thereof, and
- wherein a density of the cushion material is the densest at the lowest layer part thereof.
A cushion material structure of a vehicle seat, comprising:
- a cushion material supported by an upper surface of a bottom plate that is provided on a vehicle body,
- wherein the bottom plate includes a main surface section and a sub surface section that is arranged in front of the main surface section and that is tilted upward with respect to the main surface section,
- at least one space section is formed in the cushion material at a part corresponding to a bent section between the main surface section and the sub surface section, and
- the at least one space section has a shape in which a width gradually becomes smaller as approaching an upper side from a lower side.
