Description

  The present invention relates to a vehicle belt molding.

  Conventionally, as a belt molding for vehicles, what was indicated, for example in patent documents 1 is known. As shown in FIG. 8, the vehicle belt molding 100 is installed on a door panel 111 that partitions a door space 112 that houses a window glass 110 so as to be movable up and down. In other words, the vehicle belt molding 100 has a fixing portion 101 having a substantially U-shaped cross section that opens downwardly into which the upper end portion of the door panel 111 is inserted, and the fixing belt 101 on the side facing the window glass 110. It has a pair of seal lips 102 and 103 extending obliquely upward from the end face. These seal lips 102 and 103 are connected to the fixed portion 101 with an interval in the vertical direction, and form a space 104 in cooperation with the fixed portion 101. Both seal lips 102 and 103 open when the window glass 110 is lowered (open state) when the lower seal lip 103 is released from the window glass 110, and on the contrary, the window glass 110 rises. In the closed state (closed state), the lower seal lip 103 pressed against the window glass 110 closes due to distortion. In particular, when both the seal lips 102 and 103 are closed, the distal end portion 103 a bent toward the fixing portion 101 of the seal lip 103 is in close contact with the lower surface 102 a of the distal end portion of the seal lip 102. Thereby, it becomes difficult to produce a clearance gap between both the seal lips 102 and 103, and it is suppressed that the space 104 is flooded from between them.

US Patent Application Publication No. 2010/0011671 A1

  By the way, in Patent Document 1, if the relative positions of the window glass 110 and the seal lip 103 are shifted in the door thickness direction due to manufacturing variations of parts or assembly variations thereof, for example, both seal lips 103 are insufficient due to insufficient distortion of the seal lip 103. There is a possibility that the spaces 102 and 103 cannot be closed and the space 104 may be submerged.

  An object of the present invention is to provide a vehicular belt molding capable of suppressing flooding even if the relative position to the window glass is shifted in the door thickness direction.

  A vehicular belt molding that solves the above problems is a fixed part that is placed on the upper end of a door panel that partitions a door space that accommodates the window glass so that it can be moved up and down, and the door thickness approaches the window glass at the upper end. A fixed portion having a contacted portion projecting in a direction, a seal lip made of a resin material softer than the fixed portion, connected to the fixed portion below the contacted portion, and the seal lip The abutting portion made of a foam material is provided at the upper end of the door so as to protrude in the door thickness direction away from the window glass, and when the window glass is lowered, the seal lip is removed from the window glass. Is released from the abutted part, and when the window glass is raised, the seal lip pressed against the window glass is distorted to be elastically deformed to the abutted part. With close contact parts .

  According to this configuration, even if the contact portion with the contacted portion is sufficiently secured because the contact portion is made of a foam material, that is, even if the elastic deformation amount of the contact portion is increased. The repulsive force that the window glass receives through the seal lip can be reduced. Therefore, even if the relative position of the window glass and the seal lip is shifted in the door thickness direction due to manufacturing variation of each component or assembly variation thereof, the contact portion and the contacted portion are more surely secured. It can be made to contact closely and it can control the flooding between these contact parts and to-be-contacted parts.

About the said belt molding for vehicles, it is preferable that the to-be-contacted surface where the said contact part of the said to-be-contacted part has closely has several uneven | corrugated surface arranged in parallel with the up-down direction.
According to this configuration, the contact area between the contacted surface and the contact portion is increased by the uneven surface, thereby further suppressing water immersion between the contacted portion and the contact portion. Can do.

  The vehicle belt molding is preferably provided with a regulation protrusion at the upper end of the abutted portion that protrudes toward the door thickness direction approaching the window glass and can abut on the upper surface of the abutting portion. .

  According to this configuration, the restriction protrusion can restrict the corresponding contact portion from projecting above the contacted portion due to elastic deformation of the contact portion accompanying the contact with the contacted portion. , Can improve the appearance more.

  The present invention has an effect of suppressing flooding even when the relative position to the window glass is shifted in the door thickness direction.

Sectional drawing which shows the structure about the conventional form of the belt molding for vehicles.

  Hereinafter, an embodiment of a vehicle belt molding will be described. Hereinafter, the door thickness direction toward the vehicle interior is referred to as “vehicle inside”, and the door thickness direction toward the vehicle exterior is referred to as “vehicle outside”.

  As shown in FIG. 1, the vehicle door 1 supported by the side part of a vehicle body is provided with the door main body 2 which comprises the lower part. The door body 2 is a bag-like structure in which a door outer panel 3 serving as a door panel constituting a door outer plate and a door inner panel (not shown) constituting a door inner plate are coupled to each other through an upward opening. A window glass 4 or the like that can appear and disappear is installed.

  As shown in FIG. 2, the door outer panel 3 partitions the door space 5 which accommodates the window glass 4 so that raising / lowering is possible with a door inner panel. Accordingly, the upper end portion 3a extending substantially along the vertical direction of the door outer panel 3 forms an opening 6 for allowing the window glass 4 to appear and retract as the window glass 4 moves up and down.

  The belt molding 10 for vehicles is installed in the upper end part 3a. The vehicle belt molding 10 has a substantially constant cross section in the front-rear direction of the vehicle door 1 together with the upper end portion 3a (the direction orthogonal to the paper surface in FIG. 2). explain.

  The vehicle belt molding 10 includes a substantially U-shaped fixing portion 11 that opens downwardly into which the upper end portion 3a is inserted. This fixing | fixed part 11 consists of hard resins, such as a polypropylene, for example. A substantially triangular contacted portion 12 projects from the upper end portion of the fixed portion 11 toward the vehicle inner side. The abutted portion 12 has a substantially sloped abutting surface 12a that goes toward the vehicle interior (the door thickness direction approaching the window glass 4) as it goes upward.

  Further, the vehicle belt molding 10 includes a substantially arch-shaped seal lip 13 connected to the fixed portion 11 below the contacted portion 12. The seal lip 13 is made of a resin material that is softer than the fixed portion 11 (for example, TPO (olefin-based thermoplastic elastomer)). The seal lip 13 is partitioned into a base end portion 13b and a tip end portion 13c with the bending point 13a interposed therebetween in the longitudinal direction. The proximal end portion 13b is gradually thinned toward the bending point 13a, and the distal end portion 13c is maintained at the thickness at the bending point 13a over substantially the entire length. Then, the seal lip 13 is set so that the tip end portion 13c blocks the ascending / descending locus above the window glass 4 in a free state (elastically restored state). That is, as the window glass 4 rises, the seal lip 13 is bent and deformed (distorted) toward the contacted portion 12 with the bending point 13a as the base point while sliding the window glass 4 on the inner surface of the front end portion 13c. ). A flocking for reducing a frictional force generated between the front end portion 13c and the window glass 4 is applied to the inner surface of the vehicle.

  A substantially triangular contact portion 14 made of a foam material projects from the vehicle outer surface of the tip portion 13c toward the vehicle outer side (the door thickness direction away from the window glass 4). The contact portion 14 is separated from the contacted portion 12 when the seal lip 13 is in a free state. Further, the contact portion 14 can contact the contacted portion 12 (contacted surface 12a) when the seal lip 13 is bent and deformed with the bending point 13a as a base point as described above. The fixing part 11, the base end part 13b, and the contact part 14 cooperate to form a space S.

  Accordingly, when the window glass 4 is lowered (opened), the seal lip 13 is released from the window glass 4 so that the contact portion 14 is separated from the contacted portion 12, and as shown in FIG. In addition, when the window glass 4 is raised (closed state), the seal lip 13 pressed against the window glass 4 is distorted, so that the contact portion 14 comes into close contact with the contacted surface 12a in an elastically deformed state. .

  The abutted surface 12a is sloped, and the tip of the abutting portion 14 facing the abutted surface 12a in the bending deformation direction of the seal lip 13 is sharp, so that the bending deformation amount of the seal lip 13 is reduced. The elastic deformation amount of the contact portion 14 increases monotonously with the increase.

Next, the operation of this embodiment will be described.
Even if a sufficient amount of contact with the contacted portion 12 is ensured because the contact portion 14 is made of a foam material, that is, even if the elastic deformation amount of the contact portion 14 is increased, the seal lip 13 is interposed. Thus, the repulsive force received by the window glass 4 can be reduced.

  Therefore, as shown in FIG. 4, it is assumed that the raising / lowering position of the window glass 4 is shifted to the vehicle interior side from the original raising / lowering position shown in FIG. In this case, although the amount of bending deformation of the seal lip 13 with the bending point 13a as a base point is reduced, the contact portion 14 in close contact with the contacted surface 12a is still elastically deformed, so that the space S can be submerged. It is suppressed.

  On the other hand, as shown in FIG. 5, suppose that the raising / lowering position of the window glass 4 shifted | deviated to the vehicle outer side rather than the original raising / lowering position shown in FIG. In this case, although the amount of bending deformation of the seal lip 13 with the bending point 13a as a base point is increased and the elastic deformation of the contact portion 14 becomes excessive, the repulsive force that the window glass 4 receives through the seal lip 13 is small. Moreover, the elevating property of the window glass 4 is preferably maintained.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, since the contact portion 14 is made of a foam material, even if the contact allowance with the contacted portion 12 is sufficiently secured, that is, the amount of elastic deformation of the contact portion 14 is increased. However, the repulsive force that the window glass 4 receives through the seal lip 13 can be reduced. Therefore, even if the relative positions of the window glass 4 and the seal lip 13 are shifted in the door thickness direction due to manufacturing variations of components or their assembly variations, the contact portion 14 and the contacted portion 12 are more reliably connected. They can be in close contact with each other, making it difficult to create a gap between them. For this reason, the sealing performance by the contact part 14 and the to-be-contacted part 12 can be ensured, and the flooding to the space S from between them can be suppressed. In addition, even if the amount of elastic deformation of the contact portion 14 becomes excessive, the above-described repulsive force is small, so that the elevating and lowering properties of the window glass 4 can be suitably maintained.

  (2) In this embodiment, since water intrusion into the space S is suppressed, there is a possibility that water accumulated in the space S travels in the front-rear direction of the vehicle door 1 and is subjected to a door check mounted on the door body 2. For example, it is possible to suppress the generation of abnormal noise due to the removal of the grease applied to the door check. Alternatively, a door check cover for preventing such grease removal can be omitted.

  (3) In this embodiment, the base end portion 13b of the seal lip 13 is positioned below to form a space S between the fixed portion 11 and the sealing performance by the contact portion 14 and the contacted portion 12 is improved. By securing, it is difficult to collect water in the space S.

  (4) In the present embodiment, the space S is formed by the cooperation of the solid section fixing part 11, the seal lip 13 and the contact part 14, so that, for example, in the case of a hollow section structure in which they are integrally connected Compared with this, productivity can be further improved and accuracy can be further improved. Or since the repulsive force which the window glass 4 receives is small, the raising / lowering property of this window glass 4 can be improved more, and generation | occurrence | production of abnormal noise can be suppressed by extension.

  (5) In the present embodiment, since the contact portion 14 and the seal lip 13 that are in close contact with the contacted surface 12a are less likely to rise above the contacted portion 12, the appearance from the outside of the vehicle can be improved.

(6) In this embodiment, even if the base end portion 13b of the seal lip 13 is bent, the followability of the abutting portion 14 can ensure sealing performance and window wiping performance.
(7) In the present embodiment, the contact portion 14 is in close contact with the contacted surface 12a while being elastically deformed, and therefore does not slide with respect to the contacted surface 12a. In order to reduce the frictional force, it is not necessary to apply a low friction material to at least one surface, and the cost can be reduced.

In addition, you may change the said embodiment as follows.
As shown in FIG. 6, the abutted surface 22 to which the abutting portion 14 of the abutted portion 21 is in close contact is a vehicle belt molding 20 having a plurality of concave and convex surfaces 22a arranged in parallel in the vertical direction. Also good. In this case, in addition to the same effects as in the above-described embodiment, the contact area between the contacted surface 22 and the contact portion 14 is increased by the uneven surface 22a. Can be further suppressed.

  As shown in FIG. 7, the vehicular belt molding 30 is provided with a regulation protrusion 32 provided at the upper end of the abutted portion 31 so as to project toward the vehicle inner side and abut on the upper surface of the abutting portion 14. May be. In this case, in addition to the same effects as those of the above-described embodiment, the corresponding contact portion 14 is caused to be in contact with the contacted portion 31 by elastic deformation of the contact portion 14 accompanying contact with the contacted portion 31 as depicted by a two-dot chain line. Protruding upward can be restricted by the restricting protrusion 32, and the appearance can be further improved. In addition, you may project the control protrusion 32 in the to-be-contacted part 21 shown in FIG.

  -In the above-mentioned embodiment, fixed part 11 may consist of metal materials, such as stainless steel, for example. Alternatively, the fixing portion 11 may have a structure in which a metal reinforcing plate is joined or embedded in a resin material.

In the embodiment, the seal lip 13 may be made of a thermoplastic elastomer other than olefin, synthetic rubber, natural rubber, or the like.
-In the said embodiment, the contact part 14 may be a foam material which consists of the same soft resin as the seal lip 13, for example, a material different from the seal lip 13, such as a thermoplastic elastomer, synthetic rubber, natural rubber, etc. The foam material which consists of may be sufficient.

The vehicle belt moldings 10, 20, and 30 may be placed on the upper end portion of the door inner panel instead of the door outer panel 3 or in addition to the door outer panel 3.
-You may apply this invention to the vehicle door (what is called a back door) supported by the rear part of a vehicle body.
