  • Patent number: 4824873
    Abstract: This invention is directed to a leather-wrapped steering wheel which has a core-covering part of low hardness and high repulsion elasticity and, therefore, permits a leather wrap part to be formed through no medium of any rubber layer. This steering wheel comprises a core, a core-covering part made of semirigid urethane foam, and a leather wrap part covering the core-covering part. The semirigid urethane foam is produced by the reaction injection molding of a urethane foam material for water molding using a polyether tape compound and/or a polymer polyol type compound as a polyol moiety and a MDI type compound as a polyisocyanate moiety. This semirigid urethane foam possesses hardness in the range of 40 to 65 (Asker C), repulsion elasticity in the range of 15 to 60%, and density in the range of 0.3 to 0.5 g/cm.sup.3.
