Abstract

A vehicle seat is provided which has a pad member having a depression on its upper surface, adhesive material disposed in the depression in the pad member and a top member adhered to the pad member at the depression by the adhesive material, whereby a depression is formed in the top member and a number of decorative creases are formed along the periphery of the adhered portion of the top member. Alternatively, the top member can have a depression on its upper surface, adhesive material can be disposed on the under surface of the top member below the depression, and a pad member can be adhered to the top member at the depression by the adhesive material whereby a number of decorative creases are formed along the periphery of the adhered portion of the top member. The top member can be either a single sheet of material or an assembly formed of a sheet of material, foamed wadding, and a wadding cover. The upper surface of the top member can be provided with integral or independent buttons, with the parts of the top member immediately below the buttons adhered to depressions formed on the pad member, to form a seat with decorative buttons on its surface. The portions of the assembly forming the top member are preferably formed of an adhesible hot-melt material. The portions forming the top member assembly can be welded to form a button, the portion of the top member below the buttons being adhered to recesses in the pad member. Access holes can be provided in the recesses of the pad members so that adhesive material can be injected from the bottom side of the seat via an injector tool in order to provide adhesive material for adhering the top member to the recesses of the pad member.

Claims

1. A vehicle seat comprising:

(a) a pad member having an upper surface and at least one depression along said upper surface;

(b) adhesive material positioned on each said at least one depression;

(c) a top member having a substantially flat underside, said top member being attached to said upper pad surface along said depressions by said adhesive material, said top member being pushed into each said at least one depression, wherein said adhesive material is applied only to said pad member depressions; and

(d) at least one decorative crease formed in an upper surface of said top member at each portion of said top member which is pressed into each said at least one depression.

2. A vehicle seat in accordance with claim 1 wherein said top member comprises an upper surface, an intermediate layer of wadding and a lower wadding cover, said upper surface having at least one ornamental depression, said top layer, said intermediate layer of wadding, and said wadding cover being adhered to one another by high frequency welding.

3. The seat as recited in claim 1 wherein each said depression comprises a groove.

4. The seat as recited in claim 3 wherein said groove is substantially rectangular in shape.

5. The seat as recited in claim 1 wherein said adhesive material which is applied to said pad member depressions is adhesive hot melt material such that said top member and said pad member can be adhered together by the application of heat.

6. The seat as recited in claim 1 further comprising a frame for supporting said pad material.

7. The seat as recited in claim 2 further comprising a button adhered to each decorative crease formed in said top member.

8. The seat as recited in claim 7 wherein said button is integral with said top member.

9. The seat as recited in claim 7 wherein said button is separate from said top member.

10. The seat as recited in claim 3 further comprising a contrasting colored tape adhered to the groove formed in said top member.

11. The seat as recited in claim 1 wherein said top member comprises a single sheet of material.

12. The seat as recited in claim 1 wherein said top member comprises a plurality of rows of depressions adapted for adhering to a single depression in said pad member.

13. The seat as recited in claim 12 further comprising a contrasting colored tape disposed between the end rows of said plurality of rows of depressions.

14. The seat as recited in claim 1 wherein said pad member has first and second depressions and said top member includes a button disposed such that said button fits within said a second of said pad member depressions when said top member is adhered to said pad member.

15. The seat as recited in claim 14 further comprising a string attached to said button on one end and to a wire imbedded in said pad member on the other end such that said button is pulled into said second depression by said string.

16. The seat as recited in claim 14 wherein said button is adhered to the bottom of said second depression by an adhesive material.

17. The seat recited in claim 16 wherein said adhesive material is an adhesible hot-melt material.

18. The seat as recited in claim 1 wherein said depression on said pad member includes a projection such that when said top member is adhered to said pad member a button is formed.

19. The seat as recited in claim 1 wherein said pad member has access holes formed in each said pad member depression, said access holes extending through the bottom of said pad member such that adhesive material can be injected through said holes into each said pad member depression.
