Description

[Detailed description of the invention] (Field of industrial application) The present invention is a sealing structure for a so-called flat surface door in which the door sash is provided on the inner side of the vehicle than the door glass, especially a sealing structure at the corner of the front part of the door. Regarding.

(Prior Art) In recent years, in order to reduce the air resistance of automobiles, there has been a particular demand for the use of a flat surface surface for automobile bodies. There is an inner sash type door glass guide structure. As shown in FIG. 8, a door sash B is provided inside the vehicle from the door glass A to guide the elevation of the glass A, and a door sash B is provided between the peripheral edge A' of the glass A and the sash B. This is a configuration in which a sealing member C for sealing is provided. According to this, the door sash B can be positioned closer to the inside of the vehicle than the door glass A, and as a result, the door glass outer surface A'' and the vehicle body outer surface D In other words, the door becomes flush with the surface of the door, and the air resistance when the vehicle is running is reduced.

On the other hand, automobile doors need to be sealed with the vehicle body when closed. Therefore, in addition to the sealing member for the glass seal as described above, a sealing member for the door seal must be separately installed inside the entire periphery of the door including the door sash. According to the above, in a door sash, a sealing member for a glass seal is provided on the outside, and a sealing member for a door seal is provided on the inside. As a result, the seal structure in the sash portion becomes extremely complicated, resulting in problems such as the installation work of the seal member being time-consuming.

Therefore, it is conceivable to integrate the sealing member for the glass seal and the sealing member for the vehicle body seal to simplify the sash structure and facilitate the installation work of the sealing member. However, when the sealing member is integrated in this manner, the following problem occurs in a door in which a triangular corner bracket is provided above the front end of the door panel. In other words, in such a door, the door sash is bifurcated at the corner, and the front edge of the door glass is guided by the sash on the rear side of this branch, whereas the seal member is Since it must be installed along the outer periphery of the door, that is, along the front sash at the branch, there is no sealing member to seal the front edge of the glass on the rear sash at the branch. Become. To deal with this, a separate glass seal member is attached only to the rear part of the sash at the sash branch of the corner bracket, and the glass seal part of the integrated seal member is attached at the sash branch at the sash branch. It is conceivable to join this separately attached glass seal member, but in that case, the joint at the joint will be exposed to the outside, resulting in poor appearance, and a gap will be created at the joint, resulting in poor sealing performance. The negative effects of this will occur.

(Purpose of the invention) The present invention addresses the above-mentioned problems regarding the seal structure of a flat surface door. By integrally forming a sealing member continuously along each of the front and rear parts of the bifurcated sash, the door seal and glass seal can be installed without deteriorating the appearance at the corner bracket part. The purpose is to make sure that they are carried out well.

(Structure of the invention) In order to achieve the above object, the seal structure according to the invention is structured as follows.

That is, a door sash located on the inside of the vehicle from the door glass is provided at the top of the door panel, and the door sash is branched at a corner bracket above the front end of the door, and the portion other than the branched portion is covered by the door glass. In a flash surface door that is opened and closed, an outer peripheral flange portion provided on the outer side end surface of the door sash is provided with a glass seal portion that contacts the peripheral edge of the door glass to seal the edge, and a glass seal portion that contacts the vehicle body. A sealing member integrally formed with a door seal portion for sealing between the vehicle body and the door is attached. and,
The seal member is separated into a glass seal portion and a door seal portion in a bifurcated shape along the door sash branched at the corner bracket portion above the front end of the door, so that the glass seal portion is attached to the peripheral edge of the door glass. configured so that they abut.

According to this configuration, the door seal portion and the glass seal portion of the sealing member continuously extend along the front and rear sides of the door sash, which is bifurcated in the corner bracket portion above the front end of the door. Therefore, both the door seal and the glass seal at the front part of the door are performed satisfactorily.

(Example) Examples of the present invention will be described below.

As shown in FIG. 1, the door 2 provided on the side of the vehicle body 1 has a door panel 3 and a door glass 4 provided on the door panel 3 so as to be able to rise and fall freely. A triangular corner bracket 6 is provided so as to be located at a corner formed between the upper edge 3a of the door panel 3 and the front pillar 5 of the vehicle body 1 when the door 2 is closed.

Further, as shown in FIG. 2, a door sash 7 is attached to the door panel 3 of the door 2, the upper part of which projects above the panel 3, and the lower part of which extends into the panel 3. This door sash 7 has front and rear lifting guide parts 7a and 7b provided parallel to the lifting direction of the door glass 4 so as to guide the lifting and lowering of the door glass 4, and an inclined front edge 7c that guides the lifting and lowering of the door glass 4. The sash 7 is continuous with the similarly inclined front edge 6a of the corner bracket 6, so that the sash 7 is visually connected to the front sash 6a of the corner bracket 6 above the front part of the door panel 3.
(front edge of the corner bracket) and a rear sash section 7a (front elevation guide section).

However, as shown in FIG. 3, the sash 7 has a substantially T-shaped cross-section (inverted T-shape in the drawing) and is provided on the inside of the vehicle (upper side in the drawing) than the door glass 4. Each outer end face is an inner peripheral flange portion 8
and an outer peripheral flange portion 9, which are positioned opposite to the inner surface of the peripheral edge portion of the door glass 4. Among these, the inner peripheral flange portion 8 has a resin 10b on the outer periphery of the core material 10a.
A guide rail 10 having a substantially U-shaped cross section and covered with
is attached to the door glass 4, and a U-shaped guide block 11 fixed to the inner surface of the door glass 4 is engaged with the guide rail 10. Here, with the guide block 11 and the guide rail 10 engaged, the flexible lip 10c formed on the guide rail 10 comes into sliding contact with the inner surface of the door glass 4. Further, a garnish 12 is attached to the inner peripheral surface of the sash 7 so as to cover the guide block 11, guide rail 10, etc.

On the other hand, a seal member 13 is attached to the outer peripheral flange portion 9 of the sash 7 along the longitudinal direction of the sash 7. This seal member 13
is formed by coating a core material 14a with a resin 14b, and has a U-shaped base 14 attached to the outer peripheral flange portion 9 of the sash 7, and a flexible base 14 extending to the outside of the vehicle. The glass seal part 15 and the door seal part 16, which is also flexible and are connected to the inside of the vehicle of the base part 14, are integrally formed. When the door glass 4 is in the raised position, the glass seal portion 15 comes into contact with the peripheral edge 4a of the glass 4, and is elastically deformed from the state shown by the chain line to the state shown by the solid line, and is brought into close contact with the peripheral end 4a. At the same time, when the door 2 is closed, the protruding portion 16a of the door seal portion 16 comes into contact with the vehicle body 1 and deforms as shown by the chain line, thereby coming into close contact with the vehicle body 1. Here, the glass seal part 15 is provided with an auxiliary door seal part 17 that comes into contact with the vehicle body 1 when the door 2 is closed.
Further, as shown in FIG. 4, the sealing member 13 is
The base 14 and the door seal part 16 are separated from the upper edge 3a of the door panel 3 below, and the door seal part 16 is disposed inside the door inner panel 3', and the base 14 and the glass seal part 15 are arranged on the door panel. It is inserted between the door inner panel 3' and the door outer panel 3'' by a predetermined amount from the edge 3a. Therefore, at this protruding part, there is a gap between the end surface of the base part 14 on the inside of the vehicle and the end surface of the door seal part 16 on the outside of the vehicle. The door inner panel 3' is held between the door inner panel 3'.

However, as shown in FIGS. 5 to 7, the seal member 13 is located above the front part of the door panel 3.
is divided into a base portion 14', a glass seal portion 15', and a door seal portion 16', and is formed into a bifurcated shape. Since the base portion 14' is attached to the outer peripheral flange portion 9 of the rear sash portion (elevating guide portion) 7a of the corner bracket 6 in the same manner as the portion shown in FIG. 3, the base portion 14′ and the glass seal A portion 15' is attached along the rear sash portion 7a, so that when the door glass 4 is raised, the glass seal portions 15, 15' continuously come into contact with the periphery of the glass 4. Further, the door seal part 16' is attached along the front sash part (corner bracket front end part) 6a of the corner bracket 6, and when the door 2 is closed, a protruding part 16a' is attached to the front pillar 5 of the vehicle body 1 as shown in FIG. It is designed to abut in the same way as the part shown in . In addition, the branched door seal part 1
6' is fixed to the front end portion (front sash portion) 6a of the corner bracket using a fastener 18. Further, a garnish 19 is attached to the outer side of the corner bracket 6 as shown by the chain line in FIG.

According to such a configuration, the guide blocks 11...11 are engaged with the guide rail 10 attached to the inner peripheral flange portion 8 of the door sash 7, so that when the door glass 4 is raised or lowered by a lifting mechanism (not shown). The glass 4 is guided up and down by the up and down guide portions 7a and 7b of the door sash 7. When the door glass 4 is in the closed position, as shown in FIG.
The outer surface of the glass 4 and the outer surface of the vehicle body 1 are substantially flush with each other, and as a result, air resistance during driving is reduced. In addition, in this state, the glass seal portion 15 of the seal member 13 comes into contact with the peripheral edge 4a of the door glass 4, deforms as shown by the solid line in the same figure, and comes into close contact with the edge 4a, thereby causing the The peripheral edge 4a of the door glass 4 is sealed.

However, in the upper front part of the door panel 3,
The sash 7 is branched into a front sash portion 6a and a rear sash portion 7a of the corner bracket 6.
The door seal part 16', the base part 14', and the glass seal part 15' are divided into a rear sash part 7a.
Since the base part 14' and the glass seal part 15' are attached to the rear sash part 7a, the peripheral edge part 4a (front end part) of the door glass 4 is also sealed by the glass seal part 15'. Ru. In particular, the glass seal part 15' in the rear sash part is continuous with the glass seal part 15 above it, and there is no joining point for the glass seal part (member) at the branching point, so the appearance may be poor. I have never had a case where sealing performance deteriorated due to a gap in the joint. Further, a branched door seal portion 16' is attached to the front sash portion 6a of the corner bracket 6, but since this door seal portion 16' is also continuous with the door seal portion 16 above, the entire door 2 is closed. The door seal portion is continuously attached along the periphery, so that the sealing performance with the vehicle body 1 when the door 2 is closed does not deteriorate.

(Effects of the invention) As described above, according to the invention, in a flat surface door in which a door sash is disposed on the inside of the door glass and a corner bracket is provided above the front end of the door panel, a door sash is provided along the door sash. This type of seal structure has a structure in which the door seal part and the glass seal part are integrated into the seal member that is attached to the door, and the door seal part and the glass seal part are also formed to be continuous in the corner bracket part. This simplifies the installation process, and since there is no joint of the glass seal member on the rear side of the corner bracket, it does not look good, or the front edge of the door glass does not have a gap due to the gap created at this joint. This prevents the sealing performance from deteriorating. In this way, the seal structure for this type of flat surface door has improved installation workability.
A seal structure with excellent appearance and sealing performance is realized.
