The sealing embodiment (3) has a soft structure and has low friction. Thanks to this, it allows certain tolerance differences between guide (1 ) and glass bending. The soft structure of the sealing embodiment (3) provides low glass wear, reduces the noise caused by vibrations and reduces the effort during movement.
- The pad (4) (acting as insulation interface) has a soft structure and prevents direct contact of the guide bracket (2) made of hard material with the metal structure of the vehicle door. The noise and vibration attenuation are ensured thereof.
- The fastener (5) is preferably a part with a head and a threaded part, in the form of preferably a bolt, screw, clip, pin, while the fixing member (6) is preferably a nut (if the fastener (5) is a bolt). The fastener (5) and the fixing member (6) may be made of metal material or synthetic material. The fastener provides the mounting of the guide brackets (2) to the vehicle door. The fastener is inserted into a hole on the car door and a fixing hole (21 ) on the guide brackets (2); after being inserted into said holes, a fixing member (6) is tightened thereof. The fastener (5) and the fixing member (6) may be mounted before or after the manufacture of the guide embodiment (100).
The invention relates to a guide embodiment (100) that serves as a support and guide for car door sliding glass. The guide has a rigid structure and is made of a synthetic material. The section of the guide (1 ) has a “LT form. There are lips (31 ) in contact with the glass on the edges (121 ) of the walls (12) of the guide (1 ). Said lips (31 ) have an appearance like an extension of the walls (12) and have a flexible structure. There is a pad (4) between each guide bracket (2) and the vehicle door body. The pad (4) is made of the same material as the sealing embodiment (3). There is a fastener (5) and a fixing member (6) for mounting each guide bracket (2) to the car door body. The process steps of the production method of the guide embodiment according to the invention are as follows:
- forming the guide (1 ) and the guide bracket (2) by means of injection molding by pouring plastic material (preferably hard plastic material) on the injection mold in the injection molding machine, preferably via material 1 entry (81 ) which is located on fixed half mold (8), which has the form of guide (1 ) and guide bracket (2),
- transferring (by rotation or sliding) the formed guide (1 ) and guide bracket (2) to second set of mold cavities which are positioned in said injection mold,
- pouring the plastic material (preferably soft material) on said set of mold cavities of said injection mold which also including the sealing embodiment (3) form, preferably via material 2 entry (82) which is located on said fixed half mode (8), and forming the sealing embodiment (3) monolith to the guide through the injection molding process

In the guide embodiment (100) according to the invention, the guide (1 ), the guide bracket (2), the sealing embodiment (3) and the pad (4) can be made of any rigid or semi-rigid, thermoplastic or thermoset material. Lips (31 ) and pad (4) can be made of different materials as well.
Guide embodiment (100) according to the invention can be produced using material integrating or not fillers such glass fiber, talcum, chalk. The guide (1 ) preferably has a "LI” shaped section, but is not limited to this form. The section of the guide (1 ) can be of any form in which the sliding glass can enter and move inside the guide (1 ).
The lips (31 ) may be made of several materials with different chemistry and/or even including material of different hardness. The lips (31 ) can be made using expanded or foamed material including or not any film or foil or flocked tape. The lips (31 ) can be formed jointly with the inner base (32) by means of the contact sections (33) positioned at certain intervals on the inside of the walls (12) of the guide (1 ). Contact sections (33) can also be formed to be positioned in the entire interior of the wall (12). (Figure 5a, 5b)
The lips (31 ) have a structure, allowing their open ends to be positioned outside the guide (1 ) at the molding stage. The lips (31 ) are bent at the bending points when the glass is inserted into the guide (1 ) and their ends enter into the guide (1 ) thereof (Figure 2a, 2b, 2c). The bending points (31 1 ) are formed to preferably have a thickness less than the thickness of said lip (31 ) and provide bending of the lip (31 ) thuswise.
The pad (4) can be formed from a special injection point, by injection, or as an extension of the sealing embodiment (3) over a intermediate part (41 ) crossing through guide bracket (2). Said intermediate part (41 ) is located on a feeding channel (23) which is provided on guide bracket (2).
In the production method according to the invention, at least one part of the guide
(1 ) is in contact with the mold or part of the mold before the sealing embodiment (3) on the guide (1 ) and the pad (4) are positioned on the guide bracket (2). As preferred process, the guide (1 ) is inserted by turning or sliding into other mold blocks (other half mold (9)) (this process is called “multi-material injection”, “2K” or 3K”). As an alternative, in the production method according to the invention, the guide (1 ) and the guide bracket (2) are separated from the mold in which they were produced, and then they are taken into another mold before the sealing embodiment (3), and the pad (4) are formed on them. Transfer into the other mold can be carried out either immediately after or after the first molding, manually or semi-automatically or automatically. Second mold can be positioned on the same press machine or on a completely different press machine. This process is called "2 step” generally.
In the production method according to the invention; the guide (1 ), the guide bracket
(2), the sealing embodiment (3) and the pad can also be produced from solid, liquid or gaseous materials by means of 3D printers or developed 3D printers without the need for any mold.
