Abstract
The formation of a non-woven porous three-dimensional (3D) matrix structure that is particularly suitable for vehicle applications, such as in vehicle foam seating, to replace a portion of the foam while maintaining cushioning and defining relatively efficient airflow passageways for heating and cooling.
Claims20
A ventilated vehicular seat, comprising polymeric foam, wherein a portion of said foam is replaced with a three-dimensional non-woven self-supporting matrix structure, wherein said three-dimensional non-woven self-supporting matrix structure:
- (a) has a thickness in the range of 2.0 mm to 30.0 mm;
- (b) indicates a thickness retention at 100 lbs/ft2 of 50.0% to 100%;
- and (c) an ASTM D 737 airflow at 125 Pa of greater than or equal to 800 cubic feet per minute.
A method of forming a ventilated vehicle seat comprising:
- a. providing polymeric foam configured for a vehicle seat;
- b. replacing a portion of said foam with a three-dimensional non-woven self-supporting matrix structure, wherein said three-dimensional non-woven self-supporting matrix structure:
- (a) has a thickness in the range of 2.0 mm to 30.0 mm;
- (b) indicates a thickness retention at 100 lbs/ft2 of 50.0% to 100%;
- and (c) an ASTM D 737 airflow at 125 Pa of greater than or equal to 800 cubic feet per minute.
