Abstract
A seat cushion pad for automobiles, wherein at least a part of the seat surface portion comprises a high-resilience foam. The foam is selected such that a load ratio (3%ISR) between a load at which the thickness is 25% compressed when pressed with a pressure plate having a diameter of 60 mm (25%-strain load) and a load at which the thickness is 3% compressed when pressed with the same pressure plate (3%-strain load) is at least about 6. Alternatively, another ratio (5%ISR) between the load at which the thickness is 25% compressed when pressed with the above dimensioned pressure plate (25%-strain load) and a load at which the thickness is 5% compressed when pressed with the pressure plate (5%-strain load) is selected to be at least about 4. Such design provides comfortable seating and resistance against fatigue even during periods of extended driving, and can be prepared at a low cost with a large degree of design freedom.
