This consists of a, attached by means of an adhesive tape to a web formed by body parts, an angular profile having, made of rubber or polyvinyl chloride fastening portion and a two spaced-apart sealing lips, consisting of rubber and textile materials sealing portion. The sealing portion is arranged along its one side for latching with a recess of the fastening portion and along its other side with a web element of the body. For attachment, reference is therefore made to a specific existing or yet to be displayed structure of the body, here a shaft boundary.

The from the documents DE 20 2007 017 928 U1 and DE 201 04 747 U1 known sealing arrangements are each characterized by a formed as a hollow profile sealing portion, one side of the form-fitting, in particular lockable connection is set up with an existing plastic retaining strip, which is fixed on the body side. Instead of the retaining strip is also a, part of the body forming frame structure into consideration. Between the retaining strip or the frame structure on the one hand and the example of soft rubber, sponge rubber, thermoplastic elastomers, etc. existing fastening portion on the other hand, two or three latchable elements may be arranged. The assembly of these sealing strips is characterized by a primary insertion first of a latchable element and a subsequent pivoting movement, until finally the Verrastungszustand is reached, which can be made this case complicated movements in accordance with the number of seen in a cross section to be locked elements. This results in a comparatively complicated attachment structure.

Finally, out of the EP 1 382 474 B1 another known for the window slot of a vehicle door weatherstrip is known, which consists of a strip-like base body, on one side of two spaced-apart sealing lips and on its opposite side two likewise spaced fasteners are formed. The attachment of this weather strip requires a special body structure, which is provided with a first recess for inserting and frictionally fixing a first fastening element and a second recess intended for the positive fixing of a second fastening element. The assembly of this sealing strip is characterized in that first the first of the two fastening elements is brought into engagement with the first recess, whereupon, while pivoting the cross-sectional profile of the strip about an axis extending through the first recess of the positive engagement between the second fastening element and the second Recess is made.

However, it may also be another, from the relevant State of the art known form, especially if this assigned to the interior of the vehicle.

The Invention will be described below with reference to that in FIGS schematically reproduced embodiment closer be explained. Show it:

1 a cross-sectional view of a seal assembly according to the invention as part of a window slot of a vehicle door;

2 an isolated cross-sectional view of the sealing strip according to 1 ;

3 an enlarged partial view of a Detail III of the 2 ;

4 to 6 each successive phases of the assembly of a sealing strip according to 2 ,

With 1 is in 1 a window slot of a vehicle door called, the top-side shaft boundary 1' on an outside 2 through a body sheet 3 and on an inside 4 through two adjacent body panels 5 is formed.

A disk 6 is inside the window slot 1 between a window of the vehicle door closing and an opening position in the direction of the arrows 7 slidably received in a conventional manner. It is on both sides of the shaft boundary 1' attached, to be described below sealing strips 8th . 9 in operative connection to which sealing structures are formed, which for sealing engagement with the disc 6 are determined.

The outside 2 facing sealing strip 8th consists of a through a hollow profile 10 formed seal section 8th' and at the same time a wall portion of the hollow profile forming, approximately U-shaped mounting portion 11 , In the basic section of this U-profile 36 and at the same time a part of the hollow profile 10 performing wall section 11 ' is a U-shaped reinforcement element 12 integrated, its two-sided, to a middle section 12 ' subsequent end sections 13 . 14 in the side legs 19 . 20 of the U-profile 36 have continued.

alternative For example, the sealing portion can also be formed by an arrangement of sealing lips or a combination of a hollow profile shown with sealing lips be.

With 15 is an approximately Z-shaped, for example, metallic retaining strip referred to, at one in the direction of the window slot 1 parallel to the plane of the disc 6 folded section 16 of the body sheet 3 is attached. This stop bar 15 has end sections 17 . 18 on, for latching with the facing ends of the side legs 19 . 20 of the attachment section 11 are set up. The side legs 19 . 20 create undercuts for this purpose 30 . 31 in which, in the assembled state, the end sections 17 . 18 are included.

The retaining strip 15 can be made of metallic materials or a plastic, eg. B. consist of a thermoplastic material. Preferably, the retaining strip 15 made in accordance with a spatial, the generally curved later installation position imitating curvature and can be connected in this way without jamming with the vehicle body.

Of particular advantage is that the end sections 13 . 14 of the reinforcing element 12 into the area of the mentioned undercuts 30 . 31 extend in and according to their elastic deformation in the assembled state, the contact force between the end portions 17 . 18 of the retaining strip 15 and the side legs 19 . 20 increase or stabilize. The reinforcing element 12 thus secures the mounting position of the sealing strip on the retaining strip 15 ,

The inside 4 facing sealing strip 9 is as a U-shaped, on the, a bridge forming body panels 5 formed plugged profile. To improve the adhesion between the body panels 5 and the inside of the U-profile is the latter profiled profiled. The U-profile bears on his, the window shaft 1 facing side legs two spaced apart, for engagement with the disc 6 certain sealing lips 21 . 22 ,

To further improve the mounting position of the sealing strip 9 can be integrated within the U-profile, a preferably metallic reinforcing element, by which a contact force against the body panels 5 is increased or stabilized.

In the 2 and 3 are functional elements that match those of 1 correspondingly numbered.

As 2 can recognize is the hollow profile 10 from a relatively thick-walled, to rest on the disc 6 certain wall section 23 which, on the other hand, is relatively thin-walled, towards an upper side 24 the window shaft 1 towards extending wall sections 26 . 27 with the wall section 11 ' the hollow profile 10 completed.

With 28 is one to the approach area of the section 25 of the wall section 27 subsequent recess denotes which a deformation of the hollow profile 10 as a result of a concern of the section 23 at the disc 6 facilitated. Incidentally, this deformation is also facilitated by the aforementioned oblique orientation of the wall sections 26 . 27 ,

The end section 18 the retaining strip 15 is approximately parallel to the end portion 17 , so in conjunction with the middle section 29 an approximately Z-shaped cross-sectional structure of the retaining strip 15 is formed. About the relatively broad mean section 29 stands the retaining strip 15 in firm connection with the section 16 , This compound depending on the material can be based on a bond, a weld, a Verclipsung, riveting or screwing.

The open sides of the undercuts 30 . 31 are in a facing arrangement on the inside of the side legs of the attachment portion 11 forming U-profile 36 , They are at least partially due to the inside of the side legs 19 . 20 extending, folded end sections 13 . 14 of the approximately U-shaped reinforcing element 12 embraced laterally. By dimensioning the retaining strip 15 , in particular their end sections 17 . 18 in connection with the positioning of the undercuts 30 . 31 is an elastic state of tension represented by which the engagement of the mounting portion 11 and the retaining strip 15 is secured and at the same time, tolerance-related dimensional deviations of the retaining strip 15 take.

Due to the fold of the end section 18 opposite the middle section 16 the retaining strip 15 is between the said end portion of the body panel 3 a V-shaped recess 32 formed, in which one on the facing side legs of the mounting portion 11 molded buffer section 33 protrudes. This buffer section 33 causes not only an additional holding function for the attachment portion and a reliable sealing of the recess 32 towards the outside 2 out. In the recess 32 is the at the facing surface portions of the body panel 3 and the end section 18 adjacent buffer section 33 elastically tensioned, so that at these points a sealing effect is developed. The window shaft 1 experiences in this way a reliable seal.

To explain the installation of the sealing strip 8th on the retaining strip 15 is shown below on the representations of 4 to 6 Reference is made, in turn, the same functional elements according to the 1 to 3 are designated.

In the in 4 Initial state shown here is the existing here of a metal retaining strip 15 with the section 16 of the body sheet 3 firmly connected, z. B. welded. The retaining strip 15 has previously been subjected to a deformation, by which it has experienced, starting from an originally rectilinear shape, a curvature which exactly to the curved, the installation situation corresponding course of the section 16 , in the longitudinal extension perpendicular to the plane of the drawing 4 seen, has been adjusted. The connection of the retaining strip 15 with the section 16 is thus characterized by any constraints or elastic deformations, which could affect this connection state.

It first becomes the buffer section 33 into the recess 32 used, which, perpendicular to the plane of the 4 Seen, a pivot axis defined around which the sealing strip 8th is pivoted counterclockwise until, as in 5 shown that, the undercut 31 assigned free end 34 of the side leg 20 of the attachment section 11 on the facing side of the one end portion 17 the retaining strip 15 is applied. The other end section 18 is already in the undercut at this stage 30 introduced. Another tilt of the sealing strip 8th in the direction of the arrow 35 is with an elastic spread of the U-profile 36 connected against restoring forces coming from the end sections 13 . 14 of the amination element 12 to be generated.

The further turn in the direction of the arrow 35 Finally, as in 6 shown to a latching of the end portion 17 in the undercut 31 , under partial elastic relaxation of the reinforcing element. It is essential that in the assembled state, the engagement of the end sections 17 . 18 in the undercuts 30 . 31 is ensured by these undercuts, whose openings within the U-profile of the mounting portion 11 facing each other, from the end sections 13 . 14 the reinforcing element are embraced on the outside. In this way, in accordance with the material nature of the reinforcing element a stable over time installation state can be displayed.

A disassembly of the sealing strip 8th can be done in reverse order of the movements set out above. Dismantling is only possible if the disc is lowered lower than in a normal operational use to fully open the vehicle window. In a merely operational lowering of the disc an anti-theft device is provided, so that disassembly of the seal is prevented.

It can be seen that with the sealing strip according to the invention a montagemäßig extremely easy to handle means is provided, the assembly and disassembly can be done without the need for a special tool. However, a non-exclusive application of this sealing strip is the window slot 1 a vehicle door.
