Description

  The present invention relates to an outer weather strip for a vehicle door having a convex stabilizer that abuts against a window glass when the window glass of the vehicle is pushed outward during a closing operation or traveling.

  In general, the front and rear hinged side doors 52 and 53 of the automobile 51 shown in FIG. 2 are integrally or separately formed on a metal door panel main body 54 and the upper portion of the door panel main body 54. The door panel body 54 is composed of a door outer panel body (substitute with reference numeral 54) and a door inner panel body (not shown).

  A window glass 56 (described on the front door 52 side) is disposed between the door outer panel main body 54 and the door inner panel main body so as to be movable up and down, and is arranged at the upper edge of the door outer panel main body 54 and the door inner panel main body. A window glass insertion opening is formed, and the window glass 56 is driven up and down by a regulator (not shown) inside the door panel along the glass runs on both the front and rear sides of the door (including the door sash) 52.

  A door outer weather strip 57 made of rubber or the like is attached to the upper edge (belt line) of the door outer panel main body 54, and waterproofing, dustproofing and soundproofing are performed between the door outer panel 54 and the outer surface of the window glass 56, A door inner weather strip (not shown) is mounted on the upper edge of the door inner panel main body, and waterproofing, dustproofing and soundproofing are performed between the door inner panel and the inner side surface of the window glass. Reference numeral 58 denotes an outer weather strip on the rear door 53 side.

  For example, in Patent Document 1, as shown in FIG. 3 (A-A cross-sectional view in FIG. 2), as a door outer weather strip 57, a rigid mounting base 59 having a substantially inverted U-shaped cross section, A soft seal lip 61 projecting obliquely upward from the upper part of the inner wall 60 of the mounting base 59, and a stabilizer (projecting part) 62 integrally projecting from the lower or middle side of the inner wall 60 of the mounting base 59; (In Patent Document 1, an example in which the stabilizer 62 is disposed on the middle side (in the height direction intermediate portion) of the inner wall 60 and the stabilizer 62 is disposed on the lower side of the inner wall 60 is described. (It is described in Patent Document 2). FIG. 3 is not directly described in Patent Document 1, but is a similar creative drawing.

  A holding lip portion 63 is provided on the inner surface of the mounting base portion 59, and an upward flange portion 66 is erected on a metal door outer panel 64 and a door outer reinforcement 65, which is a reinforcing member thereof, and the flange portion 66 of the door outer panel 64. Is folded to join the flange portion 66 of the outer reinforcement 65 inward, the outer surface of the flange portion 66 is sandwiched and sealed by each holding lip portion 63, and the flange portion is formed by the claw portion 67 at the lower end of the inner wall 60 of the mounting base 59. The lower end of 66 is locked.

  The seal lip portion 61, the stabilizer 62, and the holding lip portion 63 extend in the front-rear direction of the window glass 56, that is, in the longitudinal direction of the door outer weather strip 57. As shown by an arrow 69 in FIG. 3, water droplets adhering to the outer surface of the window glass 56 fall along the upper seal lip portion 61 toward the door outer panel 64.

  The stabilizer 62 suppresses, for example, fluttering when the window glass 56 is closed, or when the window glass 56 is pushed out in the outdoor direction (arrow B direction) as indicated by a chain line when the window glass 56 is closed. The window glass 56 is prevented from coming into contact with the hard mounting base portion 59 of the door outer weather strip 57 when the door 54 (FIG. 1) is opened or closed when the door 54 (FIG. 1) is opened or closed.

  Patent Document 2 describes a door outer weather strip in which a seal lip portion (61) is disposed not on the upper side of the mounting base portion (59) having a substantially inverted U-shaped cross section but on the middle side (intermediate portion in the height direction). Yes. Patent Document 3 describes a door outer weather strip in which a pair of seal lip portions (61) are provided on both upper and lower sides of a mounting base portion (57) having a substantially inverted U-shaped cross section without providing a stabilizer 62. ing.

Japanese Patent No. 4077702 (FIGS. 1, 8, and 9) Japanese Patent No. 3412490 (FIG. 3) Japanese Patent Laying-Open No. 2005-47452 (FIG. 4)

  However, in the conventional door outer weather strip 57 of FIG. 3, the outward pushing load when the window glass 56 is closed is high as shown in FIG. 4, and the window glass 56 is, for example, a glass run (not shown). When the stabilizer 62 is pushed out to the outside of the vehicle in the range of the gap between the door 62, the door outer weather strip 57 falls down, the window glass 56 pushes the root 61a of the seal lip 61, There is a concern that the seal lip portion 61 may float (reverse) or the durability of the seal lip portion 61 may decrease. For example, when the seal lip 61 is lifted, not only the appearance is deteriorated, but also the waterproof property is reduced, or dust or sand is accumulated between the seal lip 61 and the window glass 56, and the window glass is lost. There was concern that 56 could be injured.

  FIG. 5 shows a door outer weather strip 70 (similar example of the above-mentioned Patent Document 2) in which a seal lip portion 61 is arranged on the center side in the height direction of the mounting base 59 having a substantially inverted U-shaped cross section. In this case, water droplets are likely to accumulate in the gap 71 on the outer surface side of the seal lip portion 61 as indicated by an arrow 69, and the water accumulated in the gap 71 is conveyed to the terminal portion in the longitudinal direction of the door outer weather strip 70, and the door on the terminal portion side. There was concern that the parts could have adverse effects such as rust.

  Further, when the thickness of the seal lip portion 61 is increased to cope with the extrusion of the seal lip portion 61, the sliding resistance with the window glass 56 increases, and a large load is applied to the window glass lifting system including the regulator. There was a concern of spending money.

  FIG. 6 shows a door outer weather strip 72 (similar example of the above-mentioned Patent Document 3) in which a pair of seal lip portions 61 are arranged on both upper and lower sides of a mounting base 59 having a substantially inverted U-shaped cross section. In this case, it is necessary to set a space 73 between the seal lip portions 61 so that the seal lip portions 61 do not overlap with each other, and there is a concern that the cross-sectional shape becomes large and the weight and cost increase.

  These concerns can occur not only in the front side door 54 of the automobile 51 in FIG. 2 but also in the outer weather strip 58 in the rear side door 53.

  In view of the above-described points, the present invention prevents the seal lip portion of the outer weather strip from floating when the strong pressing force acts on the window glass, and contacts the mounting base portion having a substantially inverted U-shaped cross section with the window glass.

It is a side view which shows one form of the vehicle which equip | installed the door with the outer weather strip. It is AA equivalent sectional drawing of FIG. 2 which shows one form of the outer weather strip of the conventional vehicle door. It is sectional drawing which shows the problem of the outer weather strip of the conventional vehicle door. It is sectional drawing which shows the other form of the outer weather strip of the conventional vehicle door. It is sectional drawing which shows the other form of the outer weather strip of the conventional vehicle door.

  FIG. 1 shows an embodiment of an outer weather strip for a vehicle door according to the present invention.

  This door outer weather strip 1 is made of an elastic synthetic rubber or the like as an inner wall of a mounting base 2 having a substantially inverted U-shaped cross section (one wall of the mounting base 2 having a generally inverted U-shaped cross section. 7), a seal lip 4 is provided on the upper part of the wall 3 and a first stabilizer 5 is provided on the outer surface 3a of the lower side of the inner wall 3 (surface on the side of the window glass 7). In the vicinity of the lower side of 4a, a second stabilizer 6 is projected from the outer surface 3a of the upper part of the inner wall 3.

  FIG. 1 is a view corresponding to the AA cross section of FIG. 2 of the conventional example, and is different from the door outer weather strip of FIG. 3 of the conventional example in that an upper second stabilizer 6 is arranged. Yes.

  In FIG. 1, the window glass 7 when the amount of outward movement of the vehicle is large due to a large pushing load, and the seal lip portion 4 that contacts the window glass 7 are indicated by chain lines (virtual lines). The seal lip portion 4 in a normal contact state when the extrusion load of the glass 7 is small is indicated by a solid line. In the example of FIG. 1 (a configuration example in which the upper and lower stabilizers 5 and 6 have the same protruding height H in the window glass direction), the upper and lower stabilizers 5 and 6 are simultaneously and uniformly applied to the window glass 7 when the pushing load is large. Touch (contact).

  The mounting base 2 of the door outer weather strip 1 is one wall of an inner wall 3 that is long in the vertical (vertical) direction and an outer wall that is short in the vertical direction (substantially inverted U-shaped mounting base 2). Wall) 8 and a substantially horizontal upper wall 9 connecting the inner and outer wall portions 3, 8. The inner wall 3 is inclined parallel to the window glass 7 and the outer wall 8 is also inclined substantially parallel to the window glass 7 in accordance with the inclination of the window glass 7 (falling toward the passenger compartment as it goes upward). Yes. The flange portion 12 of the door panel 11 is inserted and fixed in the inner space 10 of the mounting base portion 2 (the space surrounded by the inner wall 3, the outer wall 8, and the upper wall 9). The flange portion 12 is similarly attached to the window glass 7. It is inclined so as to be substantially parallel. The vertical position of the base portion 4 a of the seal lip portion 4 is located in the range of the thickness of the upper wall 9 at the upper portion of the inner wall 3. The root portion 4a is formed thin so as to give the seal lip portion 4 flexibility in the vehicle inside / outside direction.

  The upper surface 6a of the upper second stabilizer 6 is positioned so as to form a substantially U-shaped cross section with the lower surface of the root portion 4a (following the curved surface). When the upper stabilizer 6 is disposed in the vicinity of the root portion 4a of the seal lip portion 4, when the window glass 7 is pushed outward (when subjected to a strong pushing load) at the time of closing or high speed running, etc. The upper stabilizer 6 abuts against the outer surface 7a of the window glass 7 and receives the window glass 7, while preventing the contact (contact) between the window glass 7 and the root portion 4a of the seal lip portion 4; 4 prevents the seal lip 4 from floating. The seal lip portion 4 comes into contact with the outer surface 7a of the window glass 7 on the protruding tip side (upper side) 4b as shown by a chain line, and thereby, an increase in sliding resistance of the seal lip portion 4 is suppressed.

  The upper stabilizer 6 is formed in a substantially horizontal trapezoidal cross section, and has a protruding side surface (inner surface) 6b on the short side that is narrow in the vertical direction and can contact the outer surface 7a of the window glass 7, and the inner wall of the mounting base 2 3 is integrated with the outer surface 3a of the base plate 3 on the long side in the vertical direction, the upper surface 6a is inclined downward from the inner wall 3 toward the projecting tip surface 6b, and the projecting tip surface 6b is projected from the inner wall 3 to the projecting tip surface 6b. And a lower surface 6d inclined upward. The position of the lower surface 6d is located in the upper half of the inner wall 3. That is, the upper stabilizer 6 is located in the upper half of the inner wall 3.

  The seal lip 4 is continuous in the longitudinal direction of the door outer weather strip 1, and the upper stabilizer 6 is also a ridge that is continuous in the longitudinal direction of the door outer weather strip 1. The upper and lower stabilizers 5 and 6 may be constituted by a plurality of protrusions separated in the longitudinal direction of the door outer weather strip 1 instead of a continuous protrusion. In this case, it is necessary to form the stabilizers 5 and 6 not by extrusion molding integrated with the mounting base 2 but by separate injection molding or the like.

  A treatment 14 for reducing sliding resistance with the window glass 7 is performed on the projecting tip surfaces 5b and 6b of the upper and lower stabilizers 5 and 6 and the projecting tips of the upper and lower surfaces 5a, 5d, 6a and 6d. . The same applies to the seal surface 14 inside the seal lip 4. The seal lip portion 4 is made of a soft rubber material, and the mounting base portion 2 is made of a hard rubber material.

  The first stabilizer 5 on the lower side is arranged on the surface on the side of the window glass 7 slightly above the lower end of the inner wall 3 of the mounting base 2, outward (anti-window glass side) and obliquely upward from the lower end of the inner wall 3. A locking claw portion 15 projects from the center portion of the lower stabilizer 5 in the height direction substantially in the same horizontal line as the protruding tip 15a of the claw portion 15 (in the width direction with respect to the protruding height of the stabilizer 5). The middle part is located. For example, a space 16 in which another third stabilizer (not shown) can be disposed is provided between the upper and lower stabilizers 5 and 6.

  Similar to the upper stabilizer 6, the lower stabilizer 5 is formed in a substantially trapezoidal cross section that protrudes from the outer surface of the inner wall 3 of the mounting base 2 toward the window glass 7, and can contact the outer surface 7 a of the window glass 7. A projecting front end surface (inner side surface) 5b narrow in the vertical direction, a base portion 5c wide in the vertical direction integrated with the straight outer surface 3a of the inner side wall 3 of the mounting base 2, and a front end surface projecting from the inner side wall 3 The upper surface 5a is inclined downward toward 5b, and the lower surface 5d is inclined upward from the inner wall 3 toward the protruding tip surface 5b.

  In this example, the upper and lower stabilizers 5 and 6 have the same protruding height H in the direction of the window glass, the upper and lower stabilizers 5 and 6 have the same hardness, and the upper and lower stabilizers are pushed to the window glass 7 pushed outward. The lower stabilizer 5 prevents contact (interference) between the window glass 7 and the lower outer surface 3a of the hard inner side wall 3 and the generation of interference sound associated therewith.

  In addition, the protrusion height H to the window glass direction of the upper and lower stabilizers 5 and 6 is not restricted to being the same, and when the upper and lower stabilizers 5 and 6 have the same hardness, either the upper or lower stabilizer. It is also effective to set the protruding height (H) of 5 (6) to be higher than the protruding height (H) of either one of the stabilizers 6 (5).

  As a result, when the outward pressing force of the window glass 7 is small and it does not cause problems such as a disorder in the posture of the door outer weather strip 1 and the lifting of the seal lip 4, one of the stabilizers 5 (6 ) Only comes into contact with the window glass 7 so that the sliding resistance with the window glass 7 is kept low, and the window glass 7 is smoothly moved up and down smoothly.

  On the other hand, when the outward pressing force of the window glass 7 is large and there is a concern about the disorder of the posture of the door outer weather strip 1 or the floating of the seal lip 4, the upper and lower stabilizers 5, 6 are both It abuts against the window glass 7 and stabilizes the posture of the door outer weather strip 1, and the upper and lower stabilizers 5 and 6 both receive the pressing force of the window glass 7 and suppress the occurrence of problems in the seal lip portion 4.

  For example, when the protruding height (H) of the upper stabilizer 6 is set higher than the protruding height (H) of the lower stabilizer 5, when a large outward pressing force acts on the window glass 7, The upper stabilizer 6 positively abuts against the window glass 7 to prevent contact between the root portion 4a of the seal lip portion 4 and the window glass 7, thereby maintaining the posture of the seal lip portion 4 stably without floating.

  When the protruding height (H) of the lower stabilizer 5 is set higher than the protruding height (H) of the upper stabilizer 6, when a small outward pressing force acts on the window glass 7, The sliding resistance is lowered by contacting the window glass 7 with stable and substantially uniform force at two long intervals (spans) between the upper seal lip 4 and the lower stabilizer 5. Further, the force received from the window glass 7 is received by the lower stabilizer 5, and the locking claw portion 15 is pressed in the locking direction, thereby securely engaging the flange portion 19 and the claw portion 15 described later. Thus, it is possible to prevent the claw portion 15 from being disengaged and the outer weather strip 1 from being pulled out of the flange portion 19 as a result.

  As shown in FIG. 1, the door panel 11 includes a metal door outer panel 17 and a metal door outer reinforcement 18, and an upper end portion of the door outer panel 17 is folded downward from the rising portion 19 a and the rising portion 19 a. The flange portion 19 is formed of a folded portion 19 b, and a flange portion 20, which is an upper end portion of the door outer reinforcement 18 raised, is joined to the inside of the flange portion 19. Both flange portions 19 and 20 constitute a strong flange portion 12. The door inner panel (not shown) arranged on the inner surface 7b side of the window glass 7 also has a flange portion at the upper end portion, and a window glass insertion port 21 is formed between the flange portions of the door outer panel 17 and the door inner panel. ing.

  On the inner wall 3 of the mounting base portion 2 of the door outer weather strip 1, the locking claw portion 15 at the lower end engages with the lower end 19 c of the folded portion 19 b of the flange portion 19 of the door outer panel 17. The upper inclined locking surface 15b engages outward from the lower end 19c of the folded portion 19b from the inner side (the vehicle interior side and the window glass 7 side), and the inner surface of the inner wall 3 (the inner space of the mounting base 2). A small holding lip portion 22 arranged so as to protrude into the inner space 10 from two positions above and below the surface 10b) is in contact with the outer surface of the folded portion 19b. The upper holding lip portion 22 of the upper and lower holding lip portions 22 is formed and arranged on the opposite side of the upper stabilizer 6 with respect to the inner wall 3. The large and middle holding lip portions 23 and 24 protrude into the inner space 10 at the middle and lower positions in the vertical direction of the inner surface of the outer wall 8 of the mounting base 2 (the surface of the mounting base 2 on the inner space 10 side). The holding lip portions 23, 24 are in contact with the rising portion 19 a of the flange portion 19 and the upper surface of the door outer panel 17. Each holding lip portion 23, 24 indicates a free state when not in contact with a chain line (virtual line).

  The upper stabilizer 6 is disposed between the upper portion 19 d or the upper end portion of the flange portion 19 and the window glass 7 at a position substantially on the same horizontal line as the upper portion 19 d or the upper end portion of the flange portion 19. Thereby, when a strong pushing load is applied to the window glass 7, the upper stabilizer 6 is strongly applied to the upper portion 19 d of the flange portion 19 from the window glass 7 via the inner wall 3 of the mounting base 2 and the small holding lip 22. It is possible to transmit the extrusion load, and the upper stabilizer 6 is reinforced (supplied) at the upper part of the flange portion 19 so that the pushing force of the window glass 7 is reliably received, and problems such as lifting of the seal lip portion 4 are ensured. To prevent.

  The lower stabilizer 5 has a lower portion 19e of the folded portion 19b of the flange portion 19 at a position substantially on the same horizontal line as the lower portion 19e or the lower end portion of the folded portion 19b of the flange portion 19 and the claw portion 15 for locking. Or it arrange | positions between the lower end part and the nail | claw part 15, and the window glass 7. FIG. That is, the lower stabilizer 5 is a position that is equivalent to or slightly lower than the lower holding lip portion 22 in the upper and lower holding lip portions 22, and is used for locking the inner side wall 3. The upper half portion of the lower stabilizer 5 in the height direction is positioned at the intermediate height between the lower holding lip portion 22 and the locking claw portion. doing. As a result, when a strong pushing load is applied to the window glass 7, the lower stabilizer 5 passes through the inner wall 3 of the mounting base portion 2 and the small holding lip 22 to the lower portion 19 e of the folded portion 19 b of the flange portion 19. It becomes possible to transmit a strong extrusion load from the glass 7, and the lower stabilizer 5 is reinforced (supplied) by the lower portion 19e of the flange portion 19 to reliably receive the pushing force of the window glass 7, and the door outer weather strip. The inclination of 1 and the inclination of the seal lip portion 4 associated therewith are reliably prevented.

  At the same time, when the window glass 7 comes into contact with the lower stabilizer 5, the lower stabilizer 5 faces the claw portion 15 outward, that is, in the engagement direction of the claw portion 15 with respect to the folded portion 19 b of the flange portion 19. By pushing, the engagement (locking) state between the claw portion 15 and the lower end 19c of the folded portion 19b is stabilized, and the posture of the door outer weather strip 1 is stabilized. Thereby, even if it raises (slides) in the state in which the window glass 7 was pressed outward, the malfunction that the door outer weather strip 1 remove | deviates from the flange part 19 is prevented.

  In FIG. 1, instead of making the protrusion height (H) of the upper stabilizer 6 higher than the protrusion height (H) of the lower stabilizer 5, the protrusion heights H of the upper and lower stabilizers 5, 6. It is possible to make the hardness of the upper stabilizer 6 higher (harder) than that of the lower stabilizer 5.

  The stabilizers 5 and 6 having different hardnesses are formed by, for example, extruding the upper stabilizer 6 with a rubber material having the same hardness as that of the mounting base portion 2 and lowering the lower stabilizer 5 at the time of extrusion molding of the door outer weather strip 1. Possible by extruding with a hard rubber material, or by extruding the upper stabilizer 6 with a rubber material with the same hardness as the mounting base 2 and then injection molding the lower stabilizer 5 with a low hardness rubber material. It becomes.

  The protrusion heights of the upper and lower stabilizers 5 and 6 can be made the same, and the hardness of the lower stabilizer 5 can be made higher (harder) than the hardness of the upper stabilizer 6 by the same method as described above. Even when the upper and lower stabilizers 5 and 6 are constituted by a plurality of separated protrusions instead of the continuous protrusions in the longitudinal direction, the stabilizers 5 and 6 can be injection-molded or pasted on the extruded mounting base 2. It becomes possible. The low hardness (soft) stabilizers 5 and 6 may be formed of foamable rubber material or the like.

  In the embodiment of FIG. 1 (an example in which the protruding heights H of the upper and lower stabilizers 5, 6 are the same), each stabilizer 5, 6 is preferably formed of a rubber material having a lower hardness than the mounting base 2. For example, if each of the stabilizers 5 and 6 is formed of a soft rubber material having the same hardness as that of the seal lip portion 4, the molding operation is easy.

  In the embodiment of FIG. 1, the upper and lower stabilizers 5 and 6 are provided. However, for example, a third unillustrated stabilizer may be provided between the upper and lower stabilizers 5 and 6. In this case, it is preferable to reduce the sliding resistance with the window glass 7 by forming the vertical width dimensions of the stabilizers 5 and 6 narrower than those in FIG. In actual use, the upper and lower stabilizers 5 and 6 can sufficiently take measures against floating of the seal lip portion 4 and interference between the lower end 3c of the hard mounting base 2 and the window glass 7.

  The present invention is effective not only as an outer weather strip 1 for a vehicle front door but also as a mounting structure for an outer weather strip 1 for a vehicle rear door.

  The outer weather strip of the vehicle door according to the present invention is waterproof and sealable by preventing the seal lip from floating when the window glass is moved close to the outer weather strip by a strong outward pushing load acting on the window glass. It is used to maintain contact, etc., to prevent the contact between the mounting base and the window glass having a substantially inverted U-shaped cross section and the generation of tapping noise, and to suppress an increase in sliding resistance with the window glass. be able to.
