In the herein detailed description, the preferred configurations of the sealing profile of the invention are described only for a better understanding of the subject matter without posing any limitations.

The invention relates to a sealing profile (P) for the purpose of being used in motor vehicles. General view of the said sealing profile (P) is given in Figure 7. In motor vehicles, glasses generally are located on a panel and / or door in fixed or movable form in the rear of the vehicle. Glass guide (1) is the part guiding the movement of the said side glasses (9) in the vertical direction and are located onto the profile (P) in which the glass (9) moves. Material of the glass guide (1) is significant in terms of the durability / sustainability. All parts of the said profile (P) are held together by the virtue of the profile body (4). The glass positioning lips (2) is responsible for positioning the glasses (9) and it provides insulation against water, dust, and noise. In addition; roof glass positioning lips (2a) in the roof section, B pillar glass positioning lips (2b) in the B pillar section and C pillar glass positioning lips (2c) in the C pillar section is responsible for insulation against water, dust and noise. An inner isolation lip (3) is located between the inner channel flange (11) of the door, in which the glass (9) is located, and the plastic trim part (12). The said inner isolation lip (3) preferably has a long and thin form and serves as a damping element between the inner channel flange (11) and the plastic trim part (12). The said channel flange (11) is the part welded onto the door. On the other hand, the plastic trim part (12) is the inner trim connected to the said profile (P).

At least one bottom foot lip (5), which is included in the profile (P) structuring, enables the profile (P) to be held in the channel in which the glass (9) is located. By this manner, the bottom foot lip (5) positions the profile (P) in X and Y axes. Vehicle axis directions are given in Figure 14. According to this, X direction defines the movement direction of the vehicle, Y defines the horizontal direction perpendicular to X direction and Z defines the vertical direction.

The external flush lip (6) included in the said sealing profile (P) enables the continuity between the capping/cover outer surface (10) and the glass (9). By this manner, the sealing property is guaranteed and the said external flush lip (6) acts as a barrier between the inner and outer environments of the vehicle.

At least one base groove lip (7) is included in the profile (P) structure of the invention. The said Base Groove Lip (7), due to its grooved form, acts as a reference for positioning the profile (P) and enables the positioning of the external flush lip (6) with respect to the capping/cover outer surface (10).

Slip coat side base (8) is a TPV slip coat region which is structured for the purpose of providing long term performance during the sliding movement of the glass (9). The said region is coated with TPV (Thermoplastic Volcanizate) material with sliding properties for the purpose of providing endurance against abrasion during the movement of the glass (9).

In the invention, at least one lip (14) is structured for the purpose of providing acoustic performance and creating noise insulation. The capping/cover outer surface (10) is the visual part covering the outer surface. The capping/cover inner (13) is the part holding the capping/cover outer surface (10) in vehicle position.

The said profile (P) includes at least one bright part groove (18) for the purpose of maintaining / holding the header section (header section) in the correct position. Here, the said header section (header section), is in the roof area of the glass (9) channel group. A pillar capping (23) constitutes the header section (header section) and the front glass (9) channel sealing as a B pillar sealing.

For the header section, at least one retention lip (20) is also structured in the profile (P). The header seal outer lip (16) is covered with wool (flock) and prevents the entrance of dust and water. The header seal bottom lip (21) provides sealing for the glass (9) edge on the vehicle roof. All parts of the header section are gathered on a header seal body (22).

The said profile (P) includes at least one A pillar capping (23) for the purpose of maintaining / holding the A pillar section in the correct position. In addition, at least one A pillar outer lip (24) is also included in the profile (P) structure for the purposes of preventing the entrance of dust and water as well as balancing the final position. The said A pillar outer lip (24) has a coating.

In the invention, at least one A pillar glass guide (26) is structured for the purpose of guiding the vertical movements of the glasses (9) and is positioned onto the profile in which the glass (9) moves. All parts of the A pillar section are gathered on an A pillar body (25).

In the invention, A pillar capping (23), by the virtue of the A pillar glass guide (26), enables the glass to be fixed in Y direction and prevents a level difference (flush) between the glass (9) and the cap in this area.

In the invention, at least one C pillar glass guide (27) is structured for the purpose of guiding the vertical movements of the glasses (9) and is positioned onto the profile (P) in which the glass (9) moves. For providing the said vertical movement, at least one C pillar seal TPV coating (30) is also located on the C pillar. Also, at least one C pillar outer lip (28) is included for the purpose of preventing the entrance of dust and water. The said C pillar outer lip (28) has a coating. At least one C pillar seal isolation lip (32) is located between the inner channel flange (11) and the plastic trim part (12) for the purpose of serving as a damping element. The said C pillar seal isolation lip (32) preferably has a long and thin form. All parts of the C pillar section are gathered on a C pillar seal body (31). B pillar injection (33) in the invention provides a connection between the B pillar sealing and the roof sealing with the purpose of improving water, dust, and air insulation performance.

A pillar sealing (34a) in the invention are used to be positioned into A pillar GRC (Glass Run Channel) channel. Similarly, front door roof sealing (34b) is positioned into the roof GRC channel, front B pillar section (34c) is positioned into the B pillar GRC channel, rear B pillar section (34d) is positioned into B pillar GRC channel, rear roof sealing (34e) is positioned into roof GRC channel and C pillar sealing (34f) is positioned into bar channel.
