OUTER DOOR HANDLE GASKET FOR AUTOMOTIVE VEHICLES

Abstract

A gasket is used for sealing an interface between an outer surface of a door and a door handle of an automotive vehicle. The gasket includes opposite inner and outer surfaces, wherein the inner surface of the gasket faces the door and the outer surface of the gasket faces the handle. The gasket also includes a lip that protrudes outwardly relative to the outer surface of the gasket and extends longitudinally along an edge of the gasket to sealingly engage the handle. The lip is embossed so that it is recessed relative to the inner surface of the gasket to accommodate compression of the lip as the handle is displaced toward the door. A flattened portion extends from an end of the lip to dampen noise due to impact between the handle and a door outer panel of the door.

Description

FIELD OF THE INVENTION

The invention relates to a gasket for an outer door handle of an automotive vehicle. More particularly, the invention relates to a gasket having embossments that minimize noise associated with wind and the outer door handle impact with a door panel of the door of the vehicle.

BACKGROUND OF THE INVENTION

A vehicle door typically includes a pivoting door handle for actuating a lock or latch mechanism that retains the door to the vehicle frame. It is known in the art to provide a gasket between the handle and related bezels and the door panel to prevent water from passing there-between. It remains desirable, however, to provide an improved gasket design that minimizes noise due to wind passing over the handle and door panel and due to an impact between the handle and the door panel as the handle is released.

SUMMARY OF THE INVENTION

According to one aspect of the invention, a gasket is provided for sealing an interface between an outer surface of a door and a door handle of an automotive vehicle. The gasket includes opposite inner and outer surfaces, wherein the inner surface faces the door and the outer surface faces tie handle. The gasket also includes a lip that protrudes outwardly relative to the outer surface of the gasket to sealingly engage the handle. The lip is embossed so that it is recessed relative to the inner surface of the gasket to accommodate compression of the lip as the handle is displaced toward the door.

According to another aspect of the invention, a gasket is provided for sealing an interface between an outer surface of a door and a door handle. The gasket includes an inner surface, an outer surface, a lip and a flattened portion. The inner surface faces the door. The outer surface faces the handle. The lip extends longitudinally along an edge of the outer surface of the gasket to sealingly engage the handle. The flattened portion extends from an end of the lip to dampen noise due to contact between the handle and the outside surface of the door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a vehicle door 10 for an automotive vehicle is shown with a grip door handle 12, which is used to unlatch the door 10 from the vehicle body (not shown) prior to opening the door 10. A proximal end 14 of the handle 12 is pivotally coupled to the door 10 for movement between a released position and an unreleased position. In the released position, a distal end 16 of the handle 12 is spaced apart from an outer surface of the door 10. In the unreleased position, the distal end 16 abuts the outer surface of the door 10. The handle 12 is biased toward the unreleased position by a spring (not shown). A key opening bezel 18 is fixedly secured to the door 10 adjacent to the distal end 16 of the handle 12. Described in greater detail below, gaskets are provided for sealing the interface between the handle 12, the bezel 18 and a door outer panel 11 of the door 10.

Referring to FIG. 2-4, a first gasket 30 is used to seal an interface between the door 10 and both the bezel 18 and the distal end 16 of the handle 12 in the unreleased position. The first gasket 30 has an outer surface 36 and an opposite inner surface 46. Fasteners 34, 48 extend from opposite edges of an opening 32 formed in the first gasket 30. The fasteners 34, 48 are provided in the form of hooked tabs that extend through a hole in the door outer panel 11 to secure the first gasket 30 to the door outer panel 11. The gasket 30 is secured to the door outer panel 11 by the fasteners 34, 48. Optionally, other fasteners, such as screws or adhesives may be used.

Lips 38, 40 extends along opposite respective sides of the first gasket 30 to form a longitudinally extending seal with the bezel 18 and handle 12. The lips 38, 40 are embossed, so as to be raised relative to the outer surface 36 and recessed relative to the inner surface 46. Each lip 38, 40 has a flattened portion 42, 44 that contacts the distal end 16 of the handle 12 in the unreleased position. Alternatively, the flattened portions may be spaced apart from the lips, instead than being a portion thereof.

While uncompressed, the lips 38, 40 protrude outwardly from the outer surface 36 of the first gasket 30. The bezel 18 is assembled to the door 10 with screws or bolts and the gasket 30 is compressed between the bezel 18 and an outside surface 20 of tie door outer panel 11. The lips 38, 40 are displaced toward the door 10 due to contact with the bezel 18. The recesses along the lips 38, 40 on the inner surface 46 of the gasket 30 accommodates the displacement of the lips 38, 40 toward the door 10. Contact between the bezel 18 and the lips 38, 40 creates the longitudinally seal that prevents liquid or wind from passing there-between. Further, the use of lips 38, 40 allows the first gasket 30 to be hidden beneath the handle 12 in the unreleased position and the bezel 18.

In FIG. 4, the handle 12 is shown in the unreleased position. In this position, the handle 12 compresses the flattened portions 42, 44. The increased width or area provided by the flattened portions 42, 44 helps dampen noise and vibration associated with an impact between the handle 12 and the door outer panel 11.

In FIGS. 5 and 6, wherein like parts are indicated by like prime numerals, a second gasket is indicated at 30′. Fasteners 34′, 48′ in the form of hooked tabs secure the second gasket 30′ to the door outer panel 11. The second gasket 30′ functions substantially the same as the first gasket 30, but instead seals an interface between the door outer panel 11 and the proximal end 14 of the handle 12. The second gasket 30′ has an outer surface 36′ and an opposite inner surface 46′. The lips 38′, 40′ extends along opposite respective sides of the second gasket 30′ to form a longitudinally extending seal with the handle 12. The lips 38′, 40′ are embossed, so as to be raised relative to the outer surface 36′ and recessed relative to the inner surface 46′. The lips 38′, 40′ correspond in shape to the proximal end 14 of the handle 12.

While uncompressed, the lips 38′, 40′ protrude outwardly from the outer surface 36′ of the second gasket 30′. The handle 12 is assembled to the door 10 for pivotal movement between the unreleased and released position. As shown in FIG. 7, the second gasket 30′ is compressed between the handle 12 in the unreleased position and the outside surface 20 of the door outer panel 11. The lips 38′, 40′ are displaced toward the door 10 when the handle 12 moves to the unreleased position. The recesses along the lips 38′, 40′ on the inner surface 46′ of the second gasket 30′ accommodates the displacement of the lips 38′, 40′ toward the door 10. Contact between the handle 12 in the unreleased position and the lips 38′, 40′ creates tie longitudinally seal that prevents liquid or wind from passing there-between. Further, the use of the lips 38′, 40′ allows the second gasket 30′ to be hidden beneath the handle 12 in the unreleased position.

The gaskets 30, 30′ may be molded from rubber. Alternatively, the gaskets 30, 30′ may be formed from other suitable elastomeric or elastically flexible materials and processes known by those having ordinary skill in the art.

The invention has been described in an illustrative maimer. It is, therefore, to be understood that the terminology used is intended to be in the nature of words of description rather than of limitation. Many modifications and variations of the invention are possible in light of the above teachings. For example, in the illustrated embodiment, the lips are substantially straight to engage corresponding edges or surfaces of the bezel. It should be readily appreciated, however, that the lips may be curved or otherwise shaped to correspond with the shape of the bezel and/or handle. As another example, the gaskets may be coupled to the bezel and/or handle as a pre-assembly and held in place along the door when the bezel and/or handle are fixedly secured to the door. Thus, within the scope of the appended claims, the invention may be practiced other than as specifically described.
