Patent ID: 7691480

Claim:
A seat body comprising: a first layer which is an outermost layer of said seat body and which is formed from an elastomeric urethane composition that is free of blowing agents and comprises the reaction product of; a resin composition comprising a polyetherol, wherein said polyetherol comprises an ethylene oxide cap from 5 to 20% by weight based on the total weight of said polyetherol, and wherein said polyetherol has a number average molecular weight of from 1,500 to 10,000 g/mol, a hydroxyl number of from 20 to 100 mg KOH/g, and a nominal functionality of from 2 to 4, and an isocyanate, wherein said resin composition and said isocyanate are reacted in the presence of a catalyst comprising a metal selected from the group of titanium, zirconium and hafnium, and wherein said elastomeric urethane composition includes less than 1 part by weight of particulates per 100 parts by weight of said resin composition such that said elastomeric urethane composition is substantially free of particulates; and a second layer which is a flexible support layer to said outermost layer and comprises a urethane composition that is chemically different from said elastomeric urethane composition, wherein said urethane composition is foamed and flexible, and wherein said urethane composition comprises the reaction product of a polyol and an isocyanate reacted in the presence of water as a blowing agent.
