Patent Description:
Further, the present disclosure relates to a method for producing a sealing arrangement.

Vehicles, particularly automobiles, include a number of sealing arrangements for sealing, at interior access areas like doors, flaps, lids, etc., an interior of the vehicle against the outside.

Particularly in vehicles having four doors, a so-called B-pillar is typically provided as a part of the vehicle body, which B-pillar is arranged between the respective front and rear doors.

In order to provide this area with an aesthetic appearance, it is known to provide so-called appliques between the windows of the front and the rear doors, in order to add styling or cover unsightly portions of the vehicle.

The windows of the front and rear doors are sealed against the outside by respective sealing arrangements. Further, in many cases, another sealing arrangement is provided between the front door and the rear door. This assists in sealing off the interior of the vehicle against the outside and also contributes in reducing noise in the inside of the vehicle (e.g. passenger compartment).

In some cases, the other sealing arrangement that is provided between the front door and the rear door in the upper area of the doors (in the window area) is made part of the applique arrangement. Particularly, a margin seal is extruded separately and then adhered (e.g. by thermoplastic welding, glueing etc.) to an edge of the applique, so as to extend between the doors of the vehicle.

In some cases, the margin seal extends between an applique attached to the rear door and an applique attached to the front door of the vehicle.

Document <CIT>provides an appliqué structure for the external B pillar areas of a four door vehicle. The vehicle structure is one wherein the pair of doors on each side are hingedly mounted at the forward edges and wherein the B pillar areas are defined by the upper door edges. The appliqués are adhered to the B pillar area and form a double seal at the juncture therebetween. Additional seals are provided around the periphery of the appliqués.

Further, document <CIT> discloses a sealing assembly for sealing a corner of a closure member such as the window for an opening. The sealing assembly is attached to a frame comprising panels. Strips of a flexible material extend towards and meet at the apex of a corner and are shaped to receive the closure member at the corner. Further, the strips are adapted to be supported by a corner support which forms part of the frame. A flap of flexible material is joined to the strips in the region of the corner and bridges across the corner between the strips. The strips include an inner lip and an outer lip. The joins between the molded flap and the material of the strips are obscured from view by the lips.

Inspection of the sealing assembly known from <CIT> is difficult, as the joins are obscured from view by the lips. Further, the design flexibility for the lip cross sections is limited.

Document <CIT> relates to a corner part structure of a door glass run and intends to prevent a generation of a distortion of a corner molding part after molding. Document <CIT> relates to a relates to a window sealing and guiding channel for a window opening having a sharp corner. Documents <CIT> and <CIT> disclose further sealing arrangements with molded corner pieces.

It is the object of the present disclosure to provide an improved sealing arrangement and an improved method for producing a sealing arrangement.

The above object is achieved by sealing arrangement for sealing a closure member against a frame portion according to claim <NUM>, comprising a first sealing profile strand arranged along a first direction and having a first cross-section, a second sealing profile strand arranged along a second direction transverse to the first direction and having a second cross-section, a corner sealing portion joining the first sealing profile strand and the second sealing profile strand in a region of respective ends thereof, wherein the corner sealing portion comprises a third sealing profile strand having a third cross section and a first end and a second end, wherein the first end of the third sealing profile strand is joined to the first sealing profile strand, and wherein the second end of the third sealing profile strand is joined to the second sealing profile strand.

Further, the above object is achieved by a method for producing a sealing arrangement of claim <NUM>, comprising the steps of: extruding the first sealing profile strand, the second sealing profile strand, and the third sealing profile strand; placing the first sealing profile strand, the second sealing profile strand, and the third sealing profile strand in a mold; and joining the first sealing profile strand, the second sealing profile strand, and the third sealing profile strand by molded material so as to form the sealing arrangement with the corner sealing portion.

The closure member might be a window of a vehicle door, for example a front door.

The first sealing profile strand may be a header sealing profile strand extending essentially along a horizontal direction. The second sealing profile strand may be a B-pillar sealing profile strand extending essentially along a vertical direction.

The third sealing profile strand is a corner sealing profile strand which is produced separately from the first and the second sealing profile strand. Therefore, high design flexibility is provided. Particularly, it is possible adapt the elastic properties if the individual strands to the function to be achieved. For example, the corner sealing profile strand might be provided with an improved permanent set, so as to have a lower portion of plastic deformation (in relation to its elastic deformation), in comparison to the portion of plastic deformation of one of the other strands. High performance material might be used for the corner sealing profile strand.

Further, in some embodiments, joins between molded material and extruded material are visible, thus facilitating inspection of the produced sealing arrangement.

The third sealing profile strand is preferably arranged so as to bridge a virtual connection point between the first and second sealing profile strands. In other words, the third sealing profile strand preferably extends in a third direction which is different from the first direction and from the second direction. The first, the second, and the third sealing profile strand essentially form the shape of a triangle in the area of the corner sealing portion. While the first and the second sealing profile strand preferably extend essentially along respective straight lines, the third sealing profile strand is preferably curved.

In other words, in the third sealing profile strand is placed into a mold for producing the sealing arrangement, wherein the third sealing profile strand is inserted into the mold while being bent. Preferably, end portions of the third sealing profile strand extend essentially along the first direction and along the second direction, respectively, while an intermediate portion of the third sealing profile strand extends along an arc between the first and second sealing profile strands.

Each of the first sealing profile strand, the second sealing profile strand, and the third sealing profile strand is an extruded strand. The corner sealing portion comprises a molded portion which is molded to the first sealing profile strand, to the second sealing profile strand and to the third sealing profile strand.

The first sealing profile strand and the second sealing profile strand preferably have different cross sections and are produced by means of different extrusion tools. The third sealing profile strand has a cross section which is different from the cross sections of the first and second sealing profile strands, and is produced in another extrusion tool which is different from the tools used for the first and second sealing profile strands.

Preferably, at least some lips of the different sealing profile strands are in each case provided with a coating in order to reduce friction between the sealing profile strands and the closure member. The coating may be a flock coating, for example.

Further, it is preferred if the corner sealing portion comprises a molded portion which is molded to each of the first, second and third sealing profile strands.

The molded portion may include an essentially flat portion which extends along a plane that is defined by the first and the second direction.

Further, the molded portion may form an apex of the corner sealing portion. In other embodiments, the apex of the corner sealing portion is formed by the first and second sealing profile strands. In this case, the molded portion typically extends mainly between inner edges of the first, second and third sealing profile strands. However, the molded material of the molded portion may in any case be used to produce joins, for example between an end portion of the first sealing profile strand and an end portion of the second sealing profile strand. These end portions may be cut at right angles or may be mitre-cut, wherein molded material is provided between the cutting faces of the respective strands.

In addition, the molded material may be used to form so-called zero-gap-joins. Namely, the molded material may connect sealing profile strands which are arranged in the mold in a contiguous and directly adjacent manner, wherein the molded material is not provided directly between the end faces of the respective strands. Rather, the molded material is provided at the underside of lips of the respective strands, so as to hold the strands together and to avoid the production of a visible gap filled with molded material.

In a preferred embodiment, each of the first and second sealing profile strands comprises a first inside lip and a second inside lip for engaging the closure member.

The provision of two inside lips improves the sealing quality, both with respect to tightness and with respect to noise absorption.

The term "inside lip" refers to the fact that the lip is provided on the inside of the closure member and contacts the closure member on the inside surface thereof.

Further, it is preferred if the third sealing profile strand comprises a single inside lip.

The single inside lip has preferably a cross sectional shape which is identical to the respective first inside lips of the first and second sealing profile strands.

Therefore, it is preferred if the first end of the third sealing profile strand is joined to the first sealing profile strand in such a manner that the first inside lip of the first sealing profile strand is contiguous to the single lip at the first end of the third sealing profile strand.

As an alternative or in addition, the second end of the third sealing profile strand may be joined to the second sealing profile strand in such a manner that the first inside lip of the second sealing profile strand is contiguous to the single lip at the second end of the third sealing profile strand.

Further, it is preferred if each of the first and second sealing profile strands comprises an end lip against which may abut an end face of the closure member. This feature also contributes to improving tightness and noise absorption.

Further, it is preferred if each of the first and second sealing profile strands comprises an outside lip for engaging the closure member.

Here, the closure member can be inserted into a channel of the respective sealing profile strands, formed between at least one inside lip and at least one outside lip.

The outside lip of the second sealing profile strand may be considerably larger than the outside lip of the first sealing profile strand.

In addition, it is preferred if an inner split line which is formed by a joint between the third sealing profile strand and the molded portion of the corner sealing portion, is visible as running essentially parallel to the tip edge of an inside lip of the corner sealing portion when viewed in the direction perpendicular to the molded portion and/or perpendicular to a plane of the closure member.

The visibility of the joint facilitates inspection of the sealing arrangement, particularly with respect to the question whether the joint has been produced correctly or not.

It is understood that the joint is preferably visible if the inside lip of the corner sealing portion is not deflected by the closure member. It is particularly preferred, if the joint between the third sealing profile strand and the molded portion is visible also in case that the inside lip of the corner sealing portion is deflected by the closure element.

The viewing direction is in any case perpendicular to the molded portion and/or perpendicular to a plane of the closure member.

Further, it is preferred overall if an outer split line which is formed by a joint between a molded portion of the corner sealing portion at at least one of the first sealing profile strand and the second sealing profile strand, is visible as running essentially parallel to an outside edge of the molded portion, when viewed in a direction perpendicular to the molded portion and/or perpendicular to a plane of the closure member.

Again, this feature allows to facilitate inspection of the produced sealing direction.

Another preferred embodiment provides that the first sealing profile strand comprises a first attachment portion with a reinforcing insert which defines a U-shaped frame channel.

The frame channel is suitable for taking up a part of the frame portion. The reinforcing insert, which may be made of a metal material, allows to attach the first sealing profile strand rigidly to the frame portion.

Further, the material of at least of the first sealing profile strand, the second sealing profile strand and the third sealing profile strand is EPDM and/or TPE.

Similarly, material of the molded portion of the corner sealing portion is EPDM and/or TPE.

It is preferred, if the materials of the strands and of the molded portion are identical. However, they may be different, if necessary.

In the method for producing a sealing arrangement of the present disclosure, it is preferred if inner portions of both the first sealing profile strand and the second sealing profile strand are cut off and discarded after the extruding step and before the joining step, so that first and second ends of a single lip of the third sealing profile strand can be arranged in a mold to be contiguous to a first inside lip of the first sealing profile strand and a first inside lip of the second sealing profile strand, respectively.

In other words, the single lip of the third sealing profile strand connects the first inside lips of the first and second sealing profile strands.

The cutting step is made such that the respective sealing profile strands are partially cut, preferably in the area of the respective first inside lips, while the first and second sealing profile strands remain intact in the remaining cross sectional area and may extend to and meet at the apex of the corner.

Particularly, split lines where the first and second sealing profile strands are split, extend preferably between the first and second inside lips thereof.

The terms upper, lower, front, rear, inside, outside, etc. relate to the description of specific embodiments, but shall not limit the interpretation of the general teaching of the present disclosure.

It will be understood that the features of the invention mentioned above and those yet to be explained below can be used not only in the respective combination indicated, but also in other combinations or in isolation, without leaving the scope of the present invention.

Further, a first inside lip <NUM> and a second inside lip <NUM> extend from the B-pillar lip carrier portion <NUM> to the outside, wherein the first inside lip <NUM> is arranged far from the attachment portion <NUM> at the free end of the B-pillar lip carrier portion <NUM>.

The shapes of the first inside lip <NUM> and of the second inside lip <NUM> correspond largely to the shapes (cross sections) of the first inside lip <NUM> and the second inside lip <NUM> of the header sealing profile strand <NUM>, respectively.

Further, the B-pillar sealing profile strand <NUM> includes an embracing lip <NUM> which is arranged at the inside of the B-pillar lip carrier portion <NUM>, at the free end thereof. The embracing lip <NUM> serves to embrace a frame portion of the front door <NUM>, and is provided mainly for cosmetic reasons, although some attachment function may be assigned thereto.

Similar to the header profile split line <NUM>, a B-pillar profile split line <NUM> is provided at the B-pillar lip carrier portion <NUM> in a region between the first inside lip <NUM> and the second inside lip <NUM>.

The B-pillar sealing profile strand <NUM> is split in the area of the corner sealing portion <NUM> along the B-pillar profile split line <NUM>, wherein the part of the B-pillar sealing profile strand <NUM> which includes the first inside lip <NUM> and the embracing lip <NUM> is discarded for the length of the corner sealing portion <NUM>.

The second inside lip <NUM> extends along the full length of the B-pillar sealing profile strand <NUM>, up to the apex of the corner sealing portion <NUM>, where the split header sealing profile strand <NUM> has a split B-pillar sealing profile strand <NUM> (cf. The strands <NUM>, <NUM> can meet so as to overlap one another, as shown in <FIG>. On the other hand, the strand ends may also be mitre-cut, so as to form a mitre joint.

As is shown in <FIG>, the corner sealing profile strand <NUM> includes a single inside lip <NUM>, which is attached to a corner lip carrier portion <NUM>. While the single inside lip <NUM> extends from the corner lip carrier portion <NUM> to the outside O, an embracing (cosmetic) lip <NUM> extends from the corner lip carrier portion <NUM> to the inside I, in order to engage a corner frame portion of the front door <NUM>.

<FIG> also shows the split header sealing profile strand <NUM> from which the portion having the first inside lip <NUM> has been cut off. The molded portion <NUM> is joined to the cut off interface, along the header profile split line <NUM>,. At the outside O of the corner sealing portion <NUM>, the outer split line <NUM> is visible.

On the other hand, the corner sealing profile strand <NUM> has a joining face <NUM> at which it is joined to the molded portion <NUM>.

The position of the joint between the molded portion <NUM> and the corner sealing profile strand <NUM> is arranged such that the inner split line <NUM> is visible from the outside O. In other words, the inner split line <NUM> is visible as running essentially parallel to a tip edge of the inside lip <NUM>. As can be seen in <FIG>, the inner split line <NUM> is preferably even visible from the outside O, if the single inside lip <NUM> is deflected by the window <NUM>, as shown in a dotted line in <FIG>.

Particularly, if viewed in a direction perpendicular to the molded portion <NUM> and/or to a plane defined by the window <NUM>, there is still a distance D between the tip edge of the inside lip <NUM> and the joining face <NUM> (corresponding to the inner split line <NUM>), even if the inside lip <NUM> is deflected. The distance D is shown in <FIG>.

In brief, the sealing arrangement <NUM> is formed by extruding the header sealing profile strand <NUM> in a first extrusion tool, by extruding the B-pillar sealing profile strand <NUM> in a second extrusion tool, and by extruding the corner sealing profile strand <NUM> in a third extrusion tool.

In a second step, the corner parts of the header sealing profile strand <NUM> and the B-pillar sealing profile strand <NUM> are prepared, wherein respective inner portions of the profile strands <NUM>, <NUM> in the corner sealing portion <NUM> are cut off along the respective split lines <NUM> and <NUM>, respectively, and discarded.

In a third step, the three different sealing profile strands <NUM>, <NUM>, <NUM> are inserted into a mold which is schematically shown at <NUM> in <FIG>.

In the mold, material is injected and joined to the respective profile strands <NUM>, <NUM>, <NUM>, so as to form a molded portion <NUM>, as shown in <FIG> and <FIG>.
