Door Water-Shield and Method of Manufacturing Same

In the present invention, a vehicle door water-shield incorporates a self-sealing barrier that simplifies assembly. The raised surface may take an S-shape or a raised U-shape. The raised inverted U-shaped surface (30) is in contact with the door’s inner trim panel 18 and cantilevers outward. It provides a restorative force after deflection.

Self-sealing barrier simplifies assembly of a vehicle door

A self-sealing barrier on a vehicle door is a type of watertight seal. It is designed to attach to the inner trim panel of a vehicle door, thus preventing moisture from penetrating and entering the passenger compartment. The barrier is composed of a resilient gasket material with a spring and peripheral rail attachment surface. The barrier is then fastened to the interior surface of the door sheet metal and compresses to create a watertight seal.

A self-sealing barrier includes a cable harness 5′ and consumers 15 and 17 that are connected to each other. The cable harness 5′ is connected to the inner panel of the vehicle door and the sealing plane 2. The cable harness 5′ is attached to the cable harness 5, and the sleeve compensates for the gap between the overlapping ends of the seal element. In addition, a cable harness 5′ attached to the inner panel of the vehicle door is provided with consumers for wet and dry regions 13.

S-shaped surfaces 60

A raised S-shaped surface is generally provided along the lower extent of door-water-shield 20. This shape provides a constant deflection force to a seal material 26 without requiring a separate application of pressure to the seal material. An S-shaped surface can be a convenient design for a water-shield with a large area for a raised seal material to be positioned.

The raised attachment surface 30 is formed in a substantially continuous manner in the periphery of the inner panel of the door-water shield 20. The sidewall 56 has a length that interferes with the mating surface of the door inner panel 14.

Raised surfaces 30

The present invention is a door water-shield and a method of manufacturing the same. The door water-shield includes a barrier film body 16 with a plurality of apertures 18 disposed about its perimeter. The shield 10 is mounted to the door member 14 by fasteners, which may be pre-inserted in the door member 14 and engaged in receiving apertures of the trim panel 12.

The present invention comprises a series of end flaps that function similarly to the raised form 30. They are used to reinforce the shield 10 locally, while providing an effective seal where the raised rib 22 contacts the sealing surface 26. The bend flaps may be provided with variable lengths to meet the requirements of specific applications. The total body thickness “C” may be as low as 4 mm. In addition to this, the end flaps are reusable and re-usable.
Forming of detectable attachment surface 82

In one aspect of the present invention, the detectable attachment surface 82 is molded into a section adjacent to the periphery of the water shield. This section is detectable under an attachment force and secures the water shield to the inner panel of the door. In another aspect, the detectable attachment surface is an inverted U shape, with the cantilevered end positioned on the water shield periphery.

The form of the detectable attachment surface 82 is generally described in FIGS. 1 to 6. As can be seen, the door-water shield is attached to the inner panel of the door by a friction fit, RF welding, or clips. The detectable attachment surface is preferably formed of an elastomeric, resilient material, such as foamed polyolefins. The detectable attachment surface 82 can be formed in a flat sheet or may include apertures, recesses, or pockets.
