As described above, the center sealing for the automobile door of the present invention has a cutout formed at a side thereof, so that the air in the space inside the sealing part easily escapes to the outside when the door is closed to alleviate the impact applied to the sealing part. It is possible to increase the restoring force that can be restored to its original state when the door is opened because a plurality of diaphragms are provided to separate the inner space.

In addition, when only a cutout is formed on the side surface, the sealing part may be torn or turned over. In the present invention, since the diaphragm is provided in the middle, the tearing part of the sealing part may be prevented from being torn.

Both fixed connection portions formed on both sides of the seal have a structure without a cutout, which can also prevent the sealing portions of both sides from being torn or flipped, and both side cover portions formed at both ends of the sealing portion can prevent the tearing or overturning of both sealing portions. In addition, it is possible to wrap the outer appearance of the sealing portion, which does not impair the appearance aesthetics of the sealing.

Hereinafter, with reference to the accompanying drawings will be described in more detail the center sealing for vehicle door clearance of the present invention.

1 is a top schematic view (b), according to a preferred embodiment of the invention, FIG. 2 is a front schematic view (b), and part (a) is a cross sectional schematic view from the side in each case.

1 and 2, the center sealing 100 for a car door gap is basically shaped as an elongated strip. Since the material of the sealing is for the purpose of sealing, a rubber material having excellent elasticity and resilience is used.

FIG. 3 is a schematic cutaway cross-sectional view of the portion A-A in FIG. 2, and FIG. 4 is a schematic cutaway cross-sectional view of the portion B-B in FIG. 2.

Referring to Figures 1 to 4, the present invention, the center seal 100 for the vehicle door gap of the present invention is a fixing portion 10 is attached to the vehicle body (strictly, filler), and the upper seal It consists of a part (20). Sealing portion 20 is formed inside the space portion 25 is bent to fit the door when the door is closed, when the door is opened to restore to the original shape as shown. The sealing part 20 will be referred to as a part for shielding the external noise, preventing the inflow of foreign matters and preventing the impact by the door.
3 and 4, the sealing of the present invention has a cross-section of the lower fixing part 10 has a 'C' shape, the upper sealing part 20 of the upper part of the fixing part As a roof covering structure, the cross section of the sealing of the present invention has an approximately 'L' shape.

The fixing portion 10 is formed with an iron core 14 to reinforce strength, and has a cross-section 'c' shape so as to be attached to an automobile body. On the inner inner surface of the fixing portion 10, the locking step for preventing separation is formed in an oblique direction. In other words, the escape preventing locking step 12 is inclined inwardly and is formed in an oblique direction, so that it is not easily separated after being inserted into the pillar of the vehicle body.

The sealing part 20 formed on the upper part of the fixing part has a structure covering the fixing part like a roof (see FIG. 3), and a space part 25 is formed inside the inner part (that is, between the upper part of the fixing part and the sealing part). And, a plurality of diaphragms 26 are formed at regular intervals so that the space portion 25 is divided into a plurality of longitudinal portions by the diaphragm. As shown in FIG. 4, the diaphragm 26 is a structure that connects or blocks between the upper end of the fixing part and the sealing part strictly, and may be referred to as a partition wall of a closed structure that blocks the space part in the longitudinal direction.
Side of the sealing portion 20 is formed in the longitudinal direction along the side incision 22 is formed in the middle, the diaphragm 26 is formed in the middle of the side incision will be divided by the diaphragm 26. The thickness of the diaphragm 26 is about 0.5 mm, so the diaphragm will be referred to as a thin valve.

The reason why the side cutout 22 is formed on the side of the sealing part is to allow the air inside the space 25 to easily escape to the outside when the door is closed. This may minimize the impact on the sealing portion 20 when the door is closed.

The reason why the plurality of diaphragms 26 are formed at a predetermined interval in the sealing part is to allow the sealing part to be quickly restored to the shape as shown when the door is opened again. In addition, when only the side cutout 22 is formed, the sealing part 20 may be torn up or torn up when the sealing part 20 is torn or severely in accordance with the continuous opening and closing of the door. It can be installed to prevent the sealing part from being torn or turned over. The diaphragm 26 will be said to be necessary for improving the durability of the sealing portion. As such, the diaphragm 26 which blocks the upper end of the fixing part and the sealing part while connecting the sealing part and the fixing part prevents the sealing part from being torn or flipped off and increases the restoring force. Will be.

At both ends of the sealing portion, both side fixed connection portions 24 having a thickness of about 10 mm are formed. Both sides of the fixed connection portion 24 will be referred to as a portion without a side cut. Both sides of the fixed connection portion 24 is thicker than the diaphragm to prevent this is because both ends of the seal is the most severe external impact is applied. Both fixed connection part 24 is also to prevent the tearing and overturning of the sealing portion, which will also be closely related to the durability of the sealing portion.

Since both sides of the fixed connection portion 24 and the diaphragm 26 are not continuously formed in the entire portion, it is difficult to produce a center sealing for automobile door clearance of the present invention by the extrusion process. Thus, the center sealing for automobile door crevices of the present invention is produced by an injection process, for which the product of the present invention is produced using TPR rather than EPDM used in the conventional extrusion process. That is, the fixing part 10 and the sealing part 20 are integrally manufactured by the injection process by the injection machine.

Both side ends of the sealing portion formed on both sides of the sealing portion is formed on the upper side (30). This is not only to prevent the tearing or overturning of the both side sealing portion, but also to wrap the outer appearance of the sealing portion so as not to damage the appearance aesthetics of the sealing.

Inner inner surface of the sealing portion is provided with a force 21, to prevent the tearing of the sealing portion with the diaphragm, to increase the restoring force, and to prevent the inverted shape.

Iron cores 14 formed in the fixed portion is not formed of one long iron core, it is separated for each section divided by the diaphragm is formed a plurality. This is to improve the workability (fixing work of the seal) by allowing the seal to bend freely when the fixing part 10 is fixed to the pillar of the vehicle body.

The foregoing has outlined rather broadly the features and technical advantages of the present invention in order to better understand the claims of the invention which will be described later.
