Abstract

The invention is a seal assembly, including a polyvinyl fluoride (PVF) film bonded to a polyvinylidene fluoride (PVDF) substrate and attached to a plastic retainer element for being mounted to an aircraft passenger fixture by mounting holes formed in the retainer element through which fasteners extend into the seat. The seal is sufficiently flexible to bend into an inner sidewall of an aircraft cabin and to seal a space between the aircraft cabin fixture and the inner sidewall.

First claim

We claim:

1. An aircraft seal assembly comprising:
a. a retainer, made of a plastic, having a plurality of mounting elements for being mounted to an aircraft cabin fixture;
b. an elongate seal bonded to the retainer and comprising a flexible film bonded to a flexible substrate; and
c. wherein the elongate seal is flexible and is positioned in a space between the aircraft cabin fixture and an inner sidewall of an aircraft cabin to seal the space between the aircraft cabin fixture and the inner sidewall; and
d. wherein the retainer further comprises a pair of overlapping reciprocal retainer elements.

2. The aircraft seal assembly of claim 1 wherein the flexible film is made from a polyvinyl fluoride (VDF), and the flexible substrate is made from a polyvinylidene difluoride (PVDF).

3. The aircraft seal assembly of claim 1 wherein the flexible film is bonded to the flexible substrate with a contact adhesive.

4. The aircraft seal assembly of claim 1 wherein the elongate seal is bonded to the retainer with an epoxy bonding material.

5. The aircraft seal assembly of claim 1 wherein the elongate seal comprises a generally planar shape when not in contact with the inner sidewall.

6. The aircraft seal assembly of claim 1 wherein the plurality of mounting elements comprises holes through which a plurality of fasteners extend into the aircraft cabin fixture.

7. The aircraft seal assembly of claim 1 wherein the aircraft cabin fixture is selected from the group consisting of: aircraft passenger shells, aircraft passenger seats, aircraft cabin monuments, aircraft cabin partitions, aircraft cabin lavatories, and aircraft cabin storage components.

8. The aircraft seal assembly of claim 1 wherein the elongate seal forms a rounded V shape.

9. The aircraft seal assembly of claim 1 wherein the pair of overlapping reciprocal retainer elements are bonded to each other with an epoxy bonding material and wherein the elongate seal is bonded to the plastic retainer with an epoxy bonding material.

10. An aircraft seal assembly comprising:
a. a plastic retainer having a plurality of holes through which a plurality of fasteners pass for being mounted to an aircraft cabin fixture;
b. an elongate seal bonded with an epoxy bonding material to the plastic retainer and comprising a polyvinyl fluoride (PVD) film bonded with a contact adhesive to a polyvinylidene fluoride substrate; and
c. wherein the elongate seal comprises a generally planar shape when not in contact with an inner sidewall of an aircraft cabin, is flexible, and is positioned in a space between the aircraft cabin fixture and an inner sidewall of an aircraft cabin to seal the space between the aircraft cabin fixture and the inner sidewall.

11. The aircraft seal assembly of claim 10 wherein the polyvinylidene fluoride substrate is polyvinylidene difluoride (PVDF).

12. The aircraft seal assembly of claim 11 wherein the aircraft cabin fixture is selected from the group consisting of: aircraft passenger shells, aircraft passenger seats, aircraft cabin monuments, aircraft cabin partitions, aircraft cabin lavatories, and aircraft cabin storage components.

13. An aircraft seal assembly comprising;
a. a plastic retainer having a pair of overlapping reciprocal retainer elements, bonded to each other with an epoxy bonding material, and a plurality of holes through which a plurality of fasteners pass for being mounted to an aircraft cabin fixture;
b. an elongate seal having a rounded V shaped bonded with an epoxy bonding material at each terminus of the rounded V shape to the plastic retainer and comprising a polyvinyl fluoride film (PVF) bonded with a contact adhesive to a polyvinylidene fluoride substrate;
c. wherein the elongate seal is flexible and is positioned in a space between the aircraft fixture and an inner sidewall of an aircraft cabin to seal a space between the aircraft cabin fixture and the inner sidewall.

14. The aircraft seal assembly of claim 13 wherein the polyvinylidene fluoride substrate is polyvinylidene difluoride (PVDF).

15. The aircraft seal assembly of claim 14 wherein the aircraft cabin fixture is selected from the group consisting of: aircraft passenger shells, aircraft passenger seats, aircraft cabin monuments, aircraft cabin partitions, aircraft cabin lavatories, and aircraft cabin storage components.
