Description

  The present invention relates to an automotive weather strip.

  Generally, a door with a double door is provided at the opening of a car body (opening of a passenger compartment or cargo compartment), and one door is a first closed door that is closed first, and the other door is a rear closed door that is closed afterwards. Are known.

  In this type of automobile, for example, as described in Patent Document 1, an opening seal is provided that protrudes to the outside of the vehicle along the peripheral edge of the opening of the body. A front end-side seal that extends in the direction and projects outward is provided, and a rear closing seal that projects inward along the periphery of the rear closing door is provided.

  When the front door is closed, the inner surface of the door comes into contact with the opening seal of the body, and when viewed from the outside of the body, the front end seal of the front door and the remaining body opening seal are the peripheral edge of the rear closing door. The frame-shaped sealing means corresponding to is formed. When the rear closing door is closed, the peripheral edge of the inner surface of the door comes into contact with the frame-shaped sealing means, while the rear closing seal is positioned on the outer peripheral side of the body-shaped sealing means on the outer peripheral side and the front end of the front closing door. Abuts against the outer surface.

  In this case, the inner surface of the rear closing door rides on the front end seal of the front closing door from the opening seal of the body, and the rear rear closing seal of the rear closing door temporarily rides on the front end sealing from the outer surface of the body to the outer surface of the front closing door. It will abut. In Patent Document 2, a lip is attached to the seal of the front closing door in order to improve the sealability of the portion where the seal of the rear closing door rides on the front closing door seal from the outer surface of the body at the lower end of the front closing door. It is described that it is provided. The lip is provided so as to overlap the outer surface of the body from the outside. When the rear closing door is closed, the seal of the rear closing door rides on the seal of the first closing door from the lip.

JP 2011-219052 A Japanese Patent No. 4930788

  By the way, in order to improve the sealing performance of the part where the rear closing seal rides on the front end side seal from the outer surface of the body in the upper corner of the front end of the front closing door, the thickness of the rear closing door is increased at the upper edge portion of the front end side seal. It is preferable to provide fins that gradually become thinner toward the side. That is, the rear closing seal rides on the main body portion of the tip side seal from the fin.

  However, similarly, the portion of the corner portion on the upper end of the front end of the front closing door where the inner surface of the rear closing door rides from the opening seal of the body to the front end side seal extends from the front end side seal to the rear closing door side and the rear closing. When a fin connected to the seal side fin is provided, and the inner surface of the rear closing door runs over the tip side seal from the fin, the rear closing inner surface side fin and the rear closing continuously extending to the fin There is a problem that the sealing performance is adversely affected in the fin on the seal side.

  That is, when the rear closing door is closed, the opening seal of the body and the fin on the inner side of the rear closing door which overlaps the opening seal of the body are pressed by the inner surface of the rear closing door and deformed. Then, the fins on the inner surface side of the rear closing door are deformed, and the fins on the rear closing seal side are distorted or displaced. Since the deformation of the opening seal of the body when the rear closing door is closed is not necessarily uniform, the manner of deformation of the fin on the inner surface of the rear closing door also changes, and accordingly, the position of the fin on the rear closing seal side changes accordingly. And the state is easy to change. As described above, when the state of contact of the fin on the rear closing seal side with the outer surface of the body changes with the deformation of the fin on the inner surface side of the rear closing door, the sealing performance of the door by the rear closing seal is adversely affected.

  Then, this invention makes it a subject to further improve the sealing performance of the double doors of a car.

  In order to solve the above-described problems, the present invention is configured such that the fin on the rear closing seal side and the fin on the inner surface side of the rear closing door bend independently of each other. This will be specifically described below.

The automobile weatherstrip strip presented here relates to an automobile in which the opening of the body is opened and closed with a front-opening door and a rear-closing door.
An opening seal provided along the periphery of the opening of the body and projecting to the outside of the vehicle;
A front-end-side seal that is provided along the front-end edge of the front-closing door and projects to the outside of the vehicle;
A rear closing seal provided along the periphery of the rear closing door and projecting toward the vehicle interior;
A first end that extends to the rear closing door side on at least one side of the front end side seal of the front closing door and overlaps with the opening seal of the body when the front closing door is closed. A fin and a second fin that overlaps the outer surface of the body on the outer peripheral side of the opening seal of the body,
When the rear closing door is closed, the inner surface of the door comes into contact with the opening seal and rides from the first fin to the main body of the front-end seal of the front closing door, and is more peripheral than the opening seal. On the side, the rear closing seal contacts the outer surface of the body and rides from the second fin to the main body portion of the front side sealing of the front closing door,
The first fin and the second fin are characterized in that at least the tip portions thereof are deformed independently of each other.

  According to this weatherstrip stop, when the front door is closed, the inner surface of the door comes into contact with the opening seal of the body. The frame-shaped sealing means corresponding to the peripheral edge portion of the rear closing door is formed. When the rear closing door is closed, the inner surface of the door comes into contact with the opening seal of the body and rides from the first fin to the main body portion of the front closing door seal. Further, on the outer peripheral side of the opening seal, the rear closing seal comes into contact with the outer surface of the body and rides from the second fin to the main body portion of the front closing door seal.

  When the rear closing door is closed, the body opening seal and the first fin overlapping therewith are deformed. Although the deformation of the first fin is not necessarily uniform, the second fin can be deformed separately from the first fin, so that the influence of the deformation of the first fin on the second fin is small. Therefore, the first fin and the second fin are both sealable in the portion where the inner surface of the rear closing door rides on the front end side seal from the opening seal of the body and the portion where the rear closing seal rides on the front end side seal from the outer surface of the body. It will work effectively for improvement.

  In a preferred aspect of the present invention, the first fin and the second fin branch from the main body of the tip side seal of the front closing door and extend toward the rear closing door. According to this, the first fin and the second fin can be deformed independently of each other, the mutual deformation between the first fin and the second fin is avoided, and the sealing performance is improved. Become advantageous.

  In a preferred aspect of the present invention, each of the first fin and the second fin is thinner toward the tip. As a result, there is almost no gap between the inner surface of the rear closing door and the body opening seal at the tip of the first fin, and there is almost no gap between the rear closing seal and the outer surface of the body at the tip of the second fin. It does not occur, which is advantageous for improving the sealing performance.

  According to the present invention, the first and second fins extending toward the rear closing door are provided on the front end side seal of the first closing door, and when the rear closing door is closed, the inner surface of the door is the opening seal of the body. The rear seal is brought into contact with the outer surface of the body on the outer peripheral side of the opening seal from the first fin and from the first fin to the front side of the front door. Since the first fin and the second fin are deformed independently of each other, the first fin is deformed when the rear closing door is closed. Affects the second fin, and both the first and second fins effectively work to improve the sealing performance.

<Whole structure of the front closing seal 9 and the rear closing seal 10>
As shown in FIG. 7, the front closing seal 9 includes an inner seal 11 provided along the door upper edge, the door base end side (hinge side) side edge and the door lower edge and protruding toward the vehicle interior, and the door front end. It consists of the front end side seal | sticker 12 which is provided along the edge of the side and protrudes on the vehicle outer side. The inner seal 11 is molded at the upper corner portion on the door base end side, and the other portion is extruded. The front end side seal 12 includes a corner seal portion 13 on the upper side of the door, a corner seal portion 14 on the lower side of the door, and an intermediate seal portion 15 that connects the two. Further, a sub seal 16 extending from the upper corner seal portion 13 to the belt line position of the automobile is provided on the inner peripheral side of the intermediate seal portion 15. The upper and lower corner seal portions 13 and 14 of the first closing seal 9 are molded, and the other portions are extruded. In FIG. 7 and the like, a line L indicates the boundary between the molded part and the extruded part.

  As shown in FIG. 8, the rear closing seal 10 has a corner seal portion 17 on the upper end of the door, a corner seal portion 18 on the lower end of the door tip, and a corner seal portion 20 on the upper base end of the door. A seal portion 19A provided along the side edge on the door base end side, a seal portion 19B provided along the door lower end edge, a seal portion 19C provided along the door lower edge, and a seal portion 19D provided along the edge on the door front end side. Are both extruded. The rear closing seal 10 is attached to the inner surface side of the front door 3 and protrudes to the inside of the vehicle.

<Corner seal part 13 on the upper side of the first closing seal 9>
The upper corner seal portion 13 of the first closing seal 9 is attached to the outer surface side of the upper end corner portion of the rear door 4. As shown in FIGS. 9 and 10, the corner seal portion 13 is connected to the sub-seal 16, and a base portion 13 a that covers the edge portion 8 a on the wind glass 6 side of the front end side frame 8 from the outside of the vehicle, and an intermediate portion 8 b of the front end side frame 8. An intermediate portion 13b that covers from the vehicle exterior side, and a front end portion 13c that covers the edge portion 8c of the front frame 3 on the front door 3 side from the vehicle exterior side. The lower end portions of the base portion 13a and the intermediate portion 13b are thinner as they go downward. The distal end portion 13 c continues to the intermediate seal portion 15.

  Thus, the corner seal portion 13 includes a first fin 21 that extends from the upper portion of the tip end portion 13c toward the front door 3 and overlaps the opening seal 7 of the body 1 from the outside of the vehicle when the rear door 4 is closed. ing. Furthermore, the corner seal portion 13 extends from the upper end of the intermediate portion 13b to the front door 3 side, and when the rear door 4 is closed, the second fin 22 overlaps the outer surface 1a on the outer peripheral side of the opening seal 7 of the body 1. It has.

  Here, the first fin 21 and the second fin 22 branch from the main body portion (corner seal portion 13) of the distal end side seal 12 and extend to the front door 3 side. That is, a slit 23 is provided between the second fin 22 and the tip 13c (near the intermediate portion 13b in FIG. 9) of the corner seal portion 13 which is the base of the first fin 21. Accordingly, the first fin 21 and the second fin 22 can be deformed independently of each other. Further, the first fin 21 has a narrower vertical width as it goes to the tip, and its thickness becomes thinner as it goes to the tip. The second fin 22 is also thinner toward the tip.

<Upper corner seal portion 17 of rear closing seal 10>
The upper corner seal portion 17 of the rear closing seal 10 is attached to the inner surface side of the front end upper corner portion of the front door 3. As shown in FIGS. 9 and 11, the corner seal portion 17 is wide so that the upper portion thereof overlaps the base portion 13 a, the intermediate portion 13 b, and the tip portion 13 c of the upper corner seal portion 13 of the tip closing seal 9 from the outside of the vehicle. Is formed. Then, the corner seal portion 17 becomes narrower as it goes downward, and extends downward on the outer surface side of the intermediate portion 13b of the upper corner seal portion 13 of the first closing seal 9, and is a seal portion on the front end side of the extruded door. Following 19D.

  The upper end portion of the corner seal portion 17 is disposed so as to overlap the second fin 22 of the first closing seal 9 from the outside of the vehicle. Specifically, as shown in FIG. 12, the hollow protruding portion 19 a that protrudes toward the vehicle interior side of the seal portion 19 </ b> A extending along the upper edge of the front door 3 is the hollow protruding portion 17 a that protrudes toward the vehicle inner side of the corner seal portion 17. The hollow protrusion 17a overlaps the second fin 22 of the first closing seal 9 from the outside of the vehicle.

<Sealability in fins 21 and 22>
When the rear door 4 is closed, the peripheral edges (the door upper edge side, the door base end side, and the door lower edge side) of the inner surface abut against the opening seal 7 of the body 1. On the other hand, on the outer peripheral side of the opening seal, the inner seal 11 of the first closing seal 9 abuts on the outer surface of the body 1, and as shown in FIG. The state extends from the upper side to the lower side. As a result, the remaining opening seal 7 and front end seal 12 on the front side of the automobile form a frame-shaped sealing means corresponding to the peripheral edge of the front door 3. As shown in FIG. 10, the first fin 21 overlaps the opening seal 7 of the body 1 from the vehicle outer side and the second fin 22 overlaps the outer surface of the body 1 in the upper corner seal portion 13 of the first closing seal 9. It becomes a state.

  Next, when the front door 3 is closed, the peripheral edge portion of the inner surface thereof comes into contact with the frame-shaped sealing means including the opening seal 7 of the body 1 and the front end side seal 12 of the rear door 4. On the other hand, on the outer peripheral side of the frame-shaped sealing means, the seal portions 19A to 19C of the rear closing seal 10 abut on the outer surface of the body 1, and the seal portion 19D on the front end side of the front door 3 is on the front end side frame 8 of the rear door 4. Abuts the outer surface.

  As shown in FIG. 13, the inner surface of the front door 3 in contact with the opening seal 7 of the body 1 extends from the first fin 21 to the corner seal 13 at the upper corner seal 13 of the front seal 9. It will be in the state which got on the front-end | tip part 13c of the part 13. FIG. Further, as shown in FIG. 14, the hollow projecting portion 17 a of the corner seal portion 17 of the rear seal 10 that is in contact with the outer surface of the body 1 extends from the second fin 22 of the front seal 9 to the middle portion of the corner seal portion 13. It will be in the state which got on 13b.

  As shown in FIG. 15, when the front door 3 is closed, the opening seal 7 of the body 1 and the first fin 21 overlapping therewith are pressed against the inner surface of the front door 3 and deformed. The deformation of the opening seal 7 when the front door 3 is closed is not necessarily uniform, and therefore the deformation of the first fin 21 is also changed.

  On the other hand, since the slit 23 is provided between the tip 13c of the corner seal portion 13 and the second fin 22, the second fin 22 is not affected by the deformation of the first fin 21 and the first fin 21 is not affected. 21 can be modified separately. Accordingly, as shown in FIG. 16, when the front door 3 is closed, the second fin 22 is not displaced or abnormally deformed by the deformation of the first fin 21, and the body 1 is moved to the desired position. Keep in contact with the outer surface.

  Therefore, in the portion where the inner surface of the front door 3 runs from the opening seal 7 of the body 1 to the first closing seal 9, the effect of improving the sealing performance can be obtained by the first fin 21, and the rear closing seal 10 is removed from the outer surface of the body 1. Even in the portion that rides on the first closing seal 9, the second fin 22 can surely obtain the effect of improving the sealing performance.

<Water drainage structure>
Next, the drainage structure of the bleeding water will be described. In addition, this drainage structure is not necessarily an inseparable function from the two fins 21 and 22 branched from each other and extending from the tip side seal 12 described above.

  As shown in FIG. 14, when the second fin 22 is provided on the first closing seal 9 and the closing seal 10 rides on the main body of the first closing seal 9 from the second fin 22 after contacting the outer surface of the body 1. , Sealability is enhanced. However, when there is rain for a long time or when the water for washing the car is strongly hit, the water passes along the outer surface of the body 1 from the outer surface of the body 1 at the tip of the second fin 22 and the rear seal 10 and passes through the outer surface of the body 1. It is thought that it oozes inside.

  That is, it is a soaking of water indicated by an arrow R from the tip of the second fin 22 shown in FIG. As a countermeasure against this bleed water, a water receiver 31 and a back surface of the upper corner seal portion 13 of the tip seal 12 of the front seal 9 (the surface that is attached to the rear door 4 and is in contact with the surface of the rear door 4) A drainage channel 32 is provided.

  The water receiver 31 is formed by an extending portion that extends from the intermediate seal portion 15 to the corner seal portion 13 thereabove. The water receiver 31 includes a concave portion 33 opened on the upper surface thereof. The recess 33 is positioned below the tip of the second fin 22. As shown in FIGS. 12 and 17, when the front door 3 is closed, the water receiver 31 is closer to the proximal end side of the front door 3 than the seal portion 19 </ b> D provided along the edge of the front door 3. Located in.

  As shown in FIG. 12, the drainage channel 32 includes a drainage hole 34 and beads 35 and 36. As shown in FIGS. 18 and 19, the drain hole 34 extends obliquely downward from the recess 33 of the water receiver 31 on the distal end side of the distal end portion 13 c toward the proximal end side of the rear door 4, that is, in FIG. 19. As shown, it extends to the intermediate portion 13b on the proximal end side of the distal end portion 13c, and opens to the mounting surface side of the corner seal portion 13 with respect to the rear door 4 as shown in FIG.

  As shown in FIG. 12, the beads 35, 36 are formed at a portion of the intermediate portion 13 b on the mounting surface of the corner seal portion 13, obliquely downward from the lower end of the drainage hole 34 toward the base end side of the rear door 4 and to each other. It extends in parallel (see FIGS. 20 and 21).

  When the corner seal portion 13 is attached to the rear door 4, the beads 35 and 36 on the attachment surface abut against the outer surface of the rear door 4, and the drainage hole 34 is continuous by the attachment surface, the outer surface of the rear door 4 and the beads 35 and 36. A drainage space is formed. The lower bead 36 of the two beads 35, 36 extending obliquely extends to the lower end of the intermediate portion 13 b of the corner seal portion 13, and the lower end of the bead 36 is positioned at the base portion 13 a.

  That is, as shown in FIGS. 9 and 12, when the front door 3 is closed, the corner seal portion 17 of the rear closing seal 10 overlaps the intermediate portion 13b of the corner sealing portion 13 of the first closing seal 9, and The intermediate portion 13b is passed through and elastically contacted with the outer surface of the intermediate portion 8b of the front end side frame 8 for sealing. Specifically, the seal portion 19 </ b> D extending downward from the corner seal portion 17 is in elastic contact with the outer surface of the intermediate portion 8 b of the distal end side frame 8. In other words, the sealing surface of the rear closing seal 10 has moved from the intermediate portion 13 b of the corner sealing portion 13 of the first closing seal 9 to the outer surface of the distal end side frame 8.

  Thus, since the lower end of the bead 36 is positioned closer to the base end side of the rear door 4 than the seal portion 19D, the water guided downward by the beads 35 and 36 is closer to the base end side than the seal portion 19D in the rear door 4. Is discharged between the edge 8a and the intermediate portion 8b of the front end side frame 8.

  Therefore, it is possible to prevent the above-mentioned bleeding water from entering the vehicle, and the bleeding water falls along the outer surface of the front end side frame 8 of the rear door 4, and more specifically, from below the corner seal portion 17 of the rear closing seal 10. The seal portion 19D extending to the rear door 4 and the edge 8a of the front end side frame 8 of the rear door 4 fall down and fall between the inner panel 3a and the outer panel 3b of the front door 3, or between the inner panel 4a and the outer panel 4b of the rear door 4. Since it does not penetrate in between, such door panel rusting can be avoided.
