Multi density fiber seat back
View Patent ↗The present invention relates to a multi density fiber seat back for furniture seating systems. The multi density fiber seat back comprises an inner core of a firmer fiber batt and outer fiber batts which are relatively soft. One of the outer softer fiber batts is positioned against the front of the seat back frame and the other outer fiber batt is toward the seating area of the furniture seating system. The outer softer fiber back proximate the seating area imparts a oft plush feel to the touch. The firmer fiber batt core provides back support to one seated on the furniture and ease in raising oneself up from a seated position, as well are providing vertical stability to the multi density fiber back. The outer softer fiber batt proximate the front of the seat back frame provides a sense of reclining as it is compressed.
1. A multi density fiber seat back for furniture, comprising:
a first and a second outer fiber batt of relatively low density; and
a core of relatively high density fiber batt which is bonded between said first and said second outer fiber batts to form the multi density fiber seat back, wherein one of said outer fiber batts is placed against the seat back Fame of the furniture and the other outer fiber batt faces the seating area of the furniture;
wherein said fiber batt core and said outer fiber batts are covered with upholstery to provide a decorative multi density fiber seat back;
wherein the fiber batts are resiliently compressible, said outer fiber batt facing the seating area of the furniture providing a soft feel to the touch and said core fiber batt providing back support to one seated on the furniture and vertical stability to the multi density fiber seat back; and
wherein the ratio of softness to firmness of the multi density fiber seat back is approximately 2 to 1.
2. The multi density fiber seat back of claim 1 wherein said fiber batts comprise binder fibers having a relatively low melting temperature and carrier fibers having a relatively high melting temperature, said core fiber batt comprises a higher percentage of binder fibers than the percentage of binder fibers in said first and second outer fiber batts, said higher percentage of binder fibers providing a relatively high density core fiber batt.
3. Furniture using the multi density fiber seat back of claim 2 .
4. Furniture using the multi-density fiber seat back of claim 1 .
5. The multi density fiber seat back of claim 1 wherein the thickness of each of the fiber batts is approximately four inches.
6. A multi density fiber seat back for furniture comprising:
a first and a second outer fiber batt of relatively low density, wherein each of said outer fiber batts is formed from a homogenous blend of fibers having a relatively low melting temperature and fibers having a relatively high melting temperature;
a core of relatively high density fiber batt formed from a homogenous blend of fibers having a relatively low melting temperature and fibers having a relatively high melting temperature, wherein the homogeneous blend of fibers for said core fiber batt is of a different proportion or selection of fibers from the homogeneous blends of said outer fiber batts to provide the relatively higher density of said core fiber batt, wherein said core fiber batt is bonded between said first and said second outer fiber batts to form the multi density fiber seat back;
wherein one of said outer fiber batts is placed against the seat back frame of the furniture and the other outer fiber batt faces the seating area of the furniture;
wherein the fiber batts are resiliently compressible, said outer fiber batt facing the seating area of the furniture providing soft feel to the touch, said core fiber batt providing back support, and the other of said fiber batt against the seat back frame of the furniture providing a sense of reclining, to one seated on the furniture; and
wherein the ratio of softness to firmness of the multi density fiber seat back is approximately 2 to 1.
7. The multi density fiber seat back of claim 6 wherein said fiber batt core and said outer fiber batts are covered with upholstery to provide a decorative multi density fiber seat back.
8. Furniture using the multi density fiber seat back of claim 6 .
9. The multi density fiber seat back of claim 6 having a thickness of approximately twelve inches.
10. The multi density fiber seat back of claim 6 wherein each of said fiber batts have a thickness of approximately four inches.
