Abstract
A cushion member for use in a vehicle seat is disclosed. In this cushion member, a block body formed of a soft foam material is embedded centrally of the bottom portion of a main body of the present cushion member which is formed of a harder foam material. The block body includes side walls that are not integrally connected to the main body, or separated from the main body by hardening/impregnation preventive means, while the upper wall of the block body oriented in a perpendicular direction relative to applied loads is welded integrally to the main body by means of a hardened/impregnated layer produced during formation of the main body. With the present cushion, therefore, loads applied to the cushion member are distributed over the entire block body, and at the same time the main body will not be deformed when the cushion member itself is deformed as the loads are applied thereto.
