Description

The present invention relates to a sealing arrangement with a vehicle window of a motor vehicle, an add-on part and a sealing profile arranged between the vehicle window and add-on part, the sealing profile being designed to connect the add-on part to the vehicle window of the motor vehicle and having a holding profile comprising a holding section which is attached to the vehicle window is set or connected to this, further comprising a receiving section with a latching area for non-positive and / or positive receiving of a connection element of the attachment, which protrudes from the attachment, further comprising a support body arranged between the attachment and vehicle window, and further comprising a support body partially opposite and resiliently formed spring legs connected to it, the latching area being formed and laterally limited by the support body and the spring leg, the support body he and the free end of the spring leg define an entry opening to the latching area and, wherein the support body and / or the spring leg has one or each have an end position undercut in relation to the assembly direction, in which a latching element or latching elements of the connection element in the assembly -End position of the attachment latched or latched.

In vehicles, for example, there is an add-on part in the form of a so-called water tank cover below the vehicle front window (also called windshield), which catches water flowing off the window and discharges it laterally or by means of corresponding drainage openings. To connect a corresponding add-on part to a vehicle window, sealing arrangements of the generic type are provided, such as those in FIG DE 20 2008 006 986 U1 and the DE 20 2008 016 217 U1 are disclosed.

However, a prior art sealing arrangement is disadvantageous. An assembly worker does not receive any feedback when assembling the connection element, due to the very low assembly forces, such as B. a latching noise, so that incorrect assembly of the connection element of the attachment of the sealing arrangement can occur.

The invention therefore has the object of specifying a sealing arrangement with the features described at the outset, which can be installed more reliably than the prior art and which nevertheless enables low installation forces when installing the attachment part of the sealing arrangement.

• - a vehicle window of a motor vehicle,
• - an attachment and
• - a sealing profile arranged between the vehicle window and the attachment part,

wherein the sealing profile is designed to connect the attachment to the vehicle window of the motor vehicle and has a holding profile, comprising:

• - a holding section which is fixed to or connected to the vehicle window,
• - A receiving section with a latching area for non-positive and / or positive receiving of a connection element of the attachment, which protrudes from the attachment,
• - a support body arranged between the attachment and the vehicle window,
• - a resiliently resiliently designed spring leg which is partially opposite the support body and connected to it,

wherein the latching area is formed and laterally limited by the support body and the spring leg, the support body and the free end of the spring leg defining an entry opening to the latching area and,
wherein the support body and / or the spring leg has or have one or one end position undercut in relation to the assembly direction, in which a latching element or latching elements of the connection element latches or latches in the assembly end position of the attachment part,
wherein the support body and / or the spring leg (preferably in the area of the inlet opening) has or have a latching recess arranged in front of the end position undercut in the assembly direction or latching recesses arranged in front of the respective end position undercuts, the one or the one preceding undercut for the latching element or forms or form the latching elements, so that the latching element or the latching elements first pass through the upstream undercut or the upstream undercuts before reaching the assembly end position.

Due to the distribution of the assembly forces during assembly of the attachment over at least two undercuts following one another in the assembly direction, which are formed by the locking recess and the end position undercut, the maximum assembly forces are reduced compared to a sealing arrangement with a single undercut. The resilient spring leg enables it to be resilient due to its ability yielding to evade that the latching element or the latching elements can or can pass through the upstream undercut or the upstream undercuts, that is, allow it to be locked into or into these and then disengaged again.

At the same time, when the attachment is installed, there is clearly detectable haptic feedback and, at the same time, a characteristic multi-stage click-in sound. As a result, the attachment can be mounted more reliably and the sealing profile nevertheless enables low assembly forces when mounting the attachment of the sealing arrangement.

The locking recess or the respective locking recess can be formed in one piece with the support body or with the spring leg.

The spring leg can be L-shaped, U-shaped, V-shaped or hook-shaped in cross section.

The retaining profile is preferably designed as an extruded extruded profile.

The attachment can be a water tank or a cover or a water tank cover.

The retaining profile can have an insert made of a metallic material or of a fiber-reinforced plastic at least in some areas. The metallic material can preferably comprise aluminum, steel (in particular spring steel and / or stainless steel and / or stainless steel), copper or a copper alloy (bronze or brass).

The insert preferably has a thickness in the range from 0.05 to 0.4 mm, more preferably in the range from 0.1 to 0.3 mm, preferably in the range from 0.15 to 0.25 mm.

Typically, a polypropylene (PP), polyvinyl chloride (PVC), acrylonitrile-butadiene-styrene (ABS), ethylene-propylene-diene rubber (EPDM), thermoplastic elastomer (TPE) and / or combinations thereof is used as the material for the retaining profile of the sealing profile of the sealing arrangement used.

The retaining profile of the sealing arrangement can furthermore have a sealing element, the sealing element being arranged on the retaining profile in such a way that, after the retaining profile has been connected to the vehicle window and the attachment, it seals the vehicle window and the attachment to one another. A corresponding sealing element can in particular serve for the flush sealing of the lower edge of a vehicle window and the upper edge of the add-on part, the sealing profile, the vehicle window and the add-on part being coordinated with one another in such a way that an essentially smooth and flush surface is found on the outside (visible side of the vehicle) Transition between the vehicle window, the sealing element and the attachment results.

The holding section of the holding profile can be fixed to the vehicle window by means of an adhesive tape or an adhesive layer on the vehicle window or connected to it. A double-sided adhesive tape is preferably used. Alternatively, the holding section is fastened by means of a holding section which has a U-shaped cross section and which clamps around the corresponding edge of a vehicle window.

Part of the invention is also a motor vehicle with a sealing arrangement as described above.
