Abstract:
[Problem] To provide a seat cushion for a seat and a seat which simultaneously: 1. prevent the pelvis of a sitter from tilting backwards; 2. avoid compressing the muscle group of the sitter related to breathing; and 3. are low-cost and easy to produce and use. [Solution] In the present invention, a pelvis supporting part that supports the sacrum and/or hip bones of a sitter is formed of a hard material which can support the hard tissue of the sitter without substantial deformation, and is formed in the horizontal direction at a position and in a shape that does not compress the muscle group of the sitter related to breathing. A spinal column support, which supports the spinal column of the sitter, is formed of the same material and is formed in the vertical direction at a position and in a shape that similarly does not compress the muscle group of the sitter related to breathing.
