Seal design for vehicle and structure application
First Claim
1. An apparatus comprising:
- a seal assembly for interposition between a first surface and a second surface,the seal assembly comprising;
a seal secured to an outer perimeter of the first surface,wherein the seal comprises two layers, the first layer being a core layer and the second layer being a stiffening layer disposed over the core layer,wherein the stiffening layer comprises a magnetic material,wherein both the core layer and the stiffening layer of the seal include a neck portion and a head portion, the neck portion being proximate to the first surface, the neck portion being narrower than the head portion, andwherein the seal is elastically deformable;
a capture secured to an outer perimeter of the second surface,wherein the shape of the capture is configured to be conforming to the shape of the seal such that a portion of the capture distal to the second surface is narrower than a portion of the capture proximate to the second surface, the capture being configured to form a snug and secure fit with the seal while engaged with the seal, wherein the portion of the capture distal to the second surface directly contacts the neck portion of the seal while the capture is engaged with the seal,wherein the capture is further configured to elastically deform to allow both the core layer and the stiffening layer of the seal to be inserted into the capture, wherein the capture opens to allow placement of the seal and subsequently returns substantially to its original shape to secure the seal in place,wherein the magnetic material in the stiffening layer magnetically attracts the capture.

Abstract
Provided is a captured seal assembly that can be positioned between a first surface and a second surface of a structure or vehicle, such as an aircraft. The captured seal assembly includes a geometric-shaped seal such as a bulb-shaped seal that can be secured to an outer perimeter of the first surface and a receiving land capture that can be secured to an outer perimeter of the second surface. The geometric-shaped seal is designed to engage with the receiving land capture, and join the first surface and second surface when the geometric-shaped seal is engaged with the receiving land capture. In addition, the seal assembly can maintain a differential in pressure between a first region adjacent to the first surface and a second region adjacent to the second surface.

10. A seal assembly comprising:
-
a seal configured to be secured to an outer perimeter of a first surface wherein the seal comprises two layers, the first layer being a core layer and the second layer being a stiffening layer disposed over the core layer, wherein the stiffening layer comprises a magnetic material, wherein both the core layer and the stiffening layer of the seal include a neck portion and a head portion, the neck portion being proximate to the first surface, the neck portion being narrower than the head portion, and wherein the seal is elastically deformable; and a capture configured to be secured to an outer perimeter of a second surface, wherein the shape of the capture is configured to be conforming to the shape of the seal such that a portion of the capture distal to the second surface is narrower than a portion of the capture proximate to the second surface, the capture being configured to form a snug and secure fit with the seal while engaged with the seal, wherein the capture is further configured to elastically deform to allow both the core layer and the stiffening layer of the seal to be inserted into the capture, wherein the capture opens to allow placement of the seal and subsequently returns substantially to its original shape to secure the seal in place, wherein the portion of the capture distal to the second surface directly contacts the neck portion of the seal while the capture is engaged with the seal, wherein the magnetic material in the stiffening layer magnetically attracts the capture. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method comprising:
-
securing a seal to an outer perimeter of a first surface of an aircraft, wherein the seal comprises two layers, the first layer being a core layer and the second layer being a stiffening layer disposed over the core layer, wherein the stiffening layer comprises a magnetic material, wherein both the core layer and the stiffening layer of the seal include a neck portion and a head portion, the neck portion being proximate to the first surface, the neck portion being narrower than the head portion, and wherein the seal is elastically deformable; placing a capture on a corresponding outer perimeter of a second surface of an aircraft; engaging the seal with the capture, wherein the shape of the capture is configured to be conforming to the shape of the seal such that a portion of the capture distal to the second surface is narrower than a portion of the capture proximate to the second surface, the capture being further configured to form a snug and secure fit with the seal while engaged with the seal, wherein the capture is further configured to elastically deform to allow both the core layer and the stiffening layer of the seal to be inserted into the capture, wherein the capture opens to allow placement of the seal and subsequently returns substantially to its original shape to secure the seal in place, wherein the portion of the capture distal to the second surface directly contacts the neck portion of the seal while the capture is engaged with the seal, wherein the magnetic material in the stiffening layer magnetically attracts the capture. - View Dependent Claims (17, 18)
