Summary of the Invention

Problems to be Solved by the Invention

[0006] By the way, when taking out the luggage in the luggage compartment from the opening, there is a risk that the weatherstrip may be pulled by the luggage and come off from the lower rear end panel.

Means for Solving the Problems

[0007] The assembly structure of the vehicle weatherstrip for solving the above problems is applied to a vehicle provided with a back door that opens and closes an opening formed at the rear end surface of the vehicle body. When the back door closes the opening, the weatherstrip that seals the space between the vehicle body and the back door is assembled to the vehicle body. In the assembly structure of the vehicle weatherstrip, taking the longitudinal direction of the vehicle as the front-rear direction, when the side facing the center of the opening and the side away from the center on a virtual plane orthogonal to the front-rear direction are defined as the inner side and the outer side respectively, it includes a rear end panel that forms the opening, the weatherstrip that extends along the periphery of the opening, and an interior member that extends in the front-rear direction and covers the rear end panel from the inside. The rear end panel has a protruding portion that protrudes rearward and extends along the periphery. The interior member has a rear edge portion that protrudes outward. The weatherstrip includes a holding portion that holds the protruding portion, an opposing portion that faces the rear edge portion in the front-rear direction in front of the rear edge portion, and a sealing portion that contacts the back door.

[0008] According to the same configuration, when the weatherstrip tries to move rearward, the opposing portion of the weatherstrip contacts the rear edge portion of the interior member. As a result, the rearward movement of the weatherstrip is suppressed. Therefore, when taking out the luggage in the luggage compartment from the opening, even if the weatherstrip is dragged by the luggage, the weatherstrip is less likely to come off from the rear end panel.

[0009] In the above assembly structure of the vehicle weatherstrip, it is preferable that the opposing portion is provided at a portion of the weatherstrip that extends along the lower peripheral edge of the opening, and the interior member constitutes the floor of the luggage compartment of the vehicle.

[0010] The portion of the weatherstrip that extends along the lower peripheral edge of the opening is likely to be dragged by the luggage when taking out the luggage in the luggage compartment from the opening. In this regard, according to the above configuration, a facing portion is provided on a portion of the weatherstrip that extends along the lower peripheral edge of the opening. Therefore, when taking out the luggage in the luggage compartment from the opening, even if the weatherstrip is dragged by the luggage, it is possible to appropriately suppress the weatherstrip from coming off the rear end panel.

[0011] In the assembly structure of the vehicle weatherstrip, the weatherstrip includes an annular weatherstrip body that extends along the peripheral edge, and a restricting member that is assembled to a part of the weatherstrip body in the extending direction. The weatherstrip body has the holding portion and the sealing portion, and it is preferable that the restricting member has the facing portion.

[0012] Generally, a weatherstrip is formed by extrusion molding. For this reason, the weatherstrip has the same cross-sectional shape in the extending direction. In this case, since the facing portion is provided over the entire extending direction of the weatherstrip together with the holding portion and the sealing portion that constitute the weatherstrip, there is a possibility that the facing portion may interfere with the interior member.

[0013] In this regard, according to the above configuration, the weatherstrip is composed of a weatherstrip body and a restricting member. That is, the restricting member having the facing portion is configured as a separate body from the weatherstrip body having the holding portion and the sealing portion. Thereby, interference between the facing portion and the interior member can be suppressed.

[0014] In the assembly structure of the vehicle weatherstrip, the holding portion has a first portion located inside the protruding portion and a second portion located outside the protruding portion, and the protruding portion is sandwiched by the first portion and the second portion. The restricting member has a clamping portion including an inner portion located inside the first portion, an outer portion located outside the first portion, and a connecting portion connecting the inner portion and the outer portion, and it is preferable that the first portion is clamped by the inner portion and the outer portion.

[0015] According to the same configuration, the regulating member can be assembled to the weatherstrip body by a simple configuration in which the first portion of the weatherstrip body is sandwiched between the inner portion and the outer portion of the regulating member. Therefore, the regulating member can be assembled to an existing weatherstrip body having a first portion and a second portion.

[0016] In the assembling structure of the vehicle weatherstrip, it is preferable that the regulating member is made of a material harder than the weatherstrip body. According to the same configuration, the opposing portion is less likely to deform as compared with the case where the regulating member is made of a soft material similar to the weatherstrip body. Thereby, it is possible to effectively restrict the rearward movement of the weatherstrip by the opposing portion.

[0017] In the assembling structure of the vehicle weatherstrip, it is preferable that a protrusion protruding toward the first portion is provided on the surface of the inner portion facing the first portion.

[0018] According to the same configuration, the protrusion provided on the regulating member bites into the first portion of the weatherstrip body made of a material softer than the regulating member. Thereby, it is possible to prevent the first portion of the weatherstrip body from coming out of the clamping portion of the regulating member.

[0019] In the assembling structure of the vehicle weatherstrip, it is preferable that the clamping portion extends in the extending direction of the weatherstrip body, and the opposing portion is provided at a part in the extending direction of the clamping portion.

[0020] On the back surface of the interior member, a plurality of ribs for increasing the rigidity of the interior member may be provided at intervals. In this case, if the opposing portion is provided over the entire extending direction of the clamping portion, the opposing portion may interfere with the above ribs.

[0021] In this regard, according to the above configuration, the opposing portion is provided at a part in the extending direction of the clamping portion. Thereby, interference between the opposing portion and the rib can be suppressed. In the assembling structure of the vehicle weatherstrip, the outer portion extends in the extending direction of the weatherstrip main body, a plurality of inner portions are provided at intervals in the extending direction of the outer portion, and the opposing portion is preferably provided between adjacent inner portions.

[0022] When the opposing portion of the weatherstrip contacts the trailing edge portion of the interior member, a forward load acts on the opposing portion from the trailing edge portion. For this reason, stress tends to concentrate on the base end of the opposing portion. In this regard, according to the above configuration, there are gaps between adjacent inner portions at the portion where the opposing portion is provided in the extending direction of the outer portion. Therefore, compared with the case where there are no such gaps, the stress acting on the base end of the opposing portion can be reduced.

[0023] In the assembling structure of the vehicle weatherstrip, it is preferable that a recessed portion is provided on the surface of the inner portion facing the trailing edge portion of the interior member. According to the same configuration, while arranging the inner portion of the restricting member between the trailing edge portion of the interior member and the first portion of the weatherstrip main body, the interference between the inner portion and the trailing edge portion can be suppressed by the recessed portion provided in the inner portion. Therefore, it is not necessary to change the design of the interior member due to the provision of the restricting member.

[0024] In the assembling structure of the vehicle weatherstrip, it is preferable that a plurality of the restricting members are provided side by side at intervals in the extending direction of the weatherstrip main body.

[0025] In order to suitably suppress the weatherstrip from coming off the rear end panel, it is preferable to provide a regulating member over a wide range in the extending direction of the weatherstrip body. However, in this case, there is a risk of problems such as an increase in the size of the regulating member and difficulty in assembling the weatherstrip to the rear end panel.

[0026] In this regard, according to the above configuration, a plurality of regulating members are provided side by side with intervals in the extending direction of the weatherstrip body. For this reason, while providing regulating members over a wide range in the extending direction of the weatherstrip body, it is possible to suppress the occurrence of problems such as an increase in the size of the regulating member and deterioration in the assemblability of the weatherstrip to the rear end panel.

[0042] The connecting portion 35 connects the rear edge of the first portion 33 and the rear edge of the second portion 34. The protruding portion 17 is clamped by the first portion 33 and the second portion 34. The seal portion 32 is connected to the rear surface of the connecting portion 35. The seal portion 32 is substantially cylindrical.

[0043] The upper lip portion 36 protrudes upward from the rear part of the upper surface of the first portion 33. The upper lip portion 36 is pressed against the rear surface of the rear edge portion 18a of the scuff plate 18 (see FIG. 3).

[0044] The lower lip portion 37 protrudes downward from the front part of the lower surface of the second portion 34. The lower lip portion 37 is pressed against the rear surface of the lower extension portion 16a of the lower panel 16 (see FIG. 3).

[0045] (Regulating member 40) As shown in FIG. 2, the restricting member 40 is assembled to a part of the weatherstrip main body 30 in the extending direction. A plurality of restricting members 40 are provided at intervals along the lower peripheral edge of the opening 12 in the weatherstrip main body 30. In the present embodiment, three restricting members 40 are provided. One of the three restricting members 40 is provided at the center of the weatherstrip main body 30 in the vehicle width direction W. The remaining two restricting members 40 are provided so as to sandwich the one restricting member 40 in the vehicle width direction W.

[0046] As shown in FIGS. 3 to 5, the restricting member 40 has a clamping portion 41 and an opposing portion 45. The clamping portion 41 extends in the extending direction of the weatherstrip main body 30. The clamping portion 41 includes an inner portion 42, an outer portion 43, and a connecting portion 44.

[0047] The inner portion 42 is located above the first portion 33 and extends in the front-rear direction L and the vehicle width direction W. A plurality of inner portions 42 are provided at intervals in the vehicle width direction W. In the present embodiment, two inner portions 42 are provided.

[0048] A recessed portion 42a is provided at a portion of the upper surface of the inner portion 42 that faces the rear edge portion 18a of the scuff plate 18. The recessed portion 42a is provided over the entire inner portion 42 in the vehicle width direction W.

[0049] A protrusion 42b that protrudes toward the first portion 33 is provided at a portion of the lower surface of the inner portion 42 that faces the first portion 33. The protrusion 42b is provided at the center of the inner portion 42 in the vehicle width direction W.

[0051] The connecting portion 44 connects the front edge of the inner portion 42 and the front edge of the outer portion 43 and extends in the vehicle width direction W. The connecting portion 44 is provided over the entire outer portion 43 in the vehicle width direction W.

[0052] The opposing portion 45 projects upward from the upper edge of the connecting portion 44. As shown in FIG. 5, the opposing portion 45 is provided at the central portion of the connecting portion 44 in the vehicle width direction W. The length of the opposing portion 45 in the vehicle width direction W is smaller than the length of the clamping portion 41 in the vehicle width direction W. The opposing portion 45 is provided at a part of the clamping portion 41 in the extending direction. The opposing portion 45 is provided between the inner portions 42 adjacent to each other in the vehicle width direction W.

[0053] The regulating member 40 is made of a material harder than the weatherstrip body 30. The regulating member 40 of the present embodiment is integrally formed of a hard resin material. As shown in FIG. 3, the first portion 33 of the weatherstrip body 30 is clamped by the inner portion 42 and the outer portion 43. The outer portion 43 of the regulating member 40 and the protruding portion 17 of the rear end panel 14 are clamped by the first portion 33 and the second portion 34. The first lip 33a is sandwiched between the first portion 33 and the outer portion 43 by falling backward and toward the first portion 33. The protrusion 42b bites into the first portion 33. The second lip 34a is in contact with the lower surface of the protruding portion 17 in a state of falling backward.

[0054] The front surface of the connecting portion 44 faces the rear surface of the upper extending portion 15a of the upper panel 15 in the front-rear direction L. The opposing portion 45 faces the rear edge portion 18a in the front-rear direction L in front of the rear edge portion 18a of the scuff plate 18.

[0055] <Bumper cover 60> As shown in FIGS. 1 and 3, a bumper cover 60 is provided behind the rear end panel 14. The lower lip portion 37 of the weatherstrip body 30 is covered from behind by the upper edge of the bumper cover 60.

[0056] Note that the scuff plate 18 corresponds to the interior member according to the present invention. Next, the operation of this embodiment will be described. When the weather strip 20 tries to move rearward, the opposing portion 45 comes into contact with the trailing edge portion 18a of the scuff plate 18. As a result, the rearward movement of the weather strip 20 is suppressed. Therefore, when taking out the luggage in the luggage compartment 11 from the opening 12, even if the weather strip 20 is dragged by the luggage, it is possible to prevent the weather strip 20 from coming off the rear end panel 14.

[0057] The effects of this embodiment will be described. (1) The assembly structure of the vehicle weather strip includes a rear end panel 14 that forms the opening 12, a weather strip 20 that extends along the peripheral edge 12a of the opening 12, and a scuff plate 18 that extends in the front-rear direction L and covers the rear end panel 14 from above. The rear end panel 14 has a protruding portion 17 that protrudes rearward and extends along the peripheral edge 12a. The scuff plate 18 has a trailing edge portion 18a that protrudes downward. The weather strip 20 includes a holding portion 31 that holds the protruding portion 17, an opposing portion 45 that faces the trailing edge portion 18a in the front-rear direction L in front of the trailing edge portion 18a, and a seal portion 32 that contacts the back door 50.

[0058] According to such a configuration, since the above-described operation is achieved, it is possible to prevent the weather strip 20 from coming off the rear end panel 14. (2) The opposing portion 45 is provided at a portion of the weather strip 20 that extends along the lower peripheral edge of the opening 12.

[0059] The portion of the weather strip 20 that extends along the lower peripheral edge of the opening 12 is likely to be dragged by the luggage when taking out the luggage in the luggage compartment 11 from the opening 12. In this regard, according to the above configuration, a facing portion 45 is provided on a portion of the weather strip 20 that extends along the lower peripheral edge of the opening 12. Therefore, when taking out the luggage in the luggage compartment 11 from the opening 12, even if the weather strip 20 is dragged by the luggage, it is possible to appropriately prevent the weather strip 20 from coming off the rear end panel 14.

[0060] (3) The weather strip 20 is composed of a weather strip body 30 having a holding portion 31 and a sealing portion 32, and a regulating member 40 having a facing portion 45. The weather strip 20 will have the same cross-sectional shape in the extending direction. In this case, together with the holding portion 31 and the sealing portion 32 that constitute the weather strip 20, the facing portion 45 is provided over the entire extending direction of the weather strip 20, so there is a possibility that the facing portion 45 may interfere with the scuff plate 18.

[0061] In this regard, according to the above configuration, the weather strip 20 is composed of the weather strip body 30 and the regulating member 40. That is, the regulating member 40 having the facing portion 45 is configured as a separate body from the weather strip body 30 having the holding portion 31 and the sealing portion 32. Thereby, interference between the facing portion 45 and the scuff plate 18 can be suppressed.

[0062] (4) The holding portion 31 sandwiches the protruding portion 17 between the first portion 33 and the second portion 34. The regulating member 40 sandwiches the first portion 33 between the inner portion 42 and the outer portion 43. According to such a configuration, the regulating member 40 can be assembled to the weather strip body 30 by a simple configuration of sandwiching the first portion 33 of the weather strip body 30 between the inner portion 42 and the outer portion 43 of the regulating member 40. Therefore, the regulating member 40 can be assembled to the existing weather strip body 30 having the first portion 33 and the second portion 34.

[0063] (5) The regulating member 40 is made of a material harder than the weather strip body 30. According to such a configuration, the opposing portion 45 is less likely to deform as compared with the case where the regulating member 40 is made of a soft material similar to the weatherstrip main body 30. Thereby, it is possible to effectively regulate the backward movement of the weatherstrip 20 by the opposing portion 45.

[0064] (6) The inner portion 42 is provided with a protrusion 42b. According to such a configuration, the protrusion 42b bites into the first portion 33 of the weatherstrip main body 30 made of a material softer than the regulating member 40. Thereby, it is possible to suppress the first portion 33 of the weatherstrip main body 30 from coming out of the clamping portion 41 of the regulating member 40.

[0065] (7) The clamping portion 41 extends in the extending direction of the weatherstrip main body 30. The opposing portion 45 is provided at a part in the extending direction of the clamping portion 41. On the back surface of the scuff plate 18, a plurality of ribs for increasing the rigidity of the scuff plate 18 may be provided at intervals. In this case, if the opposing portion 45 is provided over the entire extending direction of the clamping portion 41, the opposing portion 45 may interfere with the above ribs.

[0066] In this regard, according to the present embodiment, the opposing portion 45 is provided at a part in the extending direction of the clamping portion 41. Thereby, interference between the opposing portion 45 and the above ribs can be suppressed. (8) The opposing portion 45 is provided between adjacent inner portions 42.

[0067] When the opposing portion 45 of the weatherstrip 20 contacts the trailing edge portion 18a of the scuff plate 18, a forward load acts on the opposing portion 45 from the trailing edge portion 18a. For this reason, stress is likely to concentrate on the proximal end of the opposing portion 45.

[0068] In this regard, according to the above configuration, in the portion where the opposing portion 45 is provided in the extending direction of the outer portion 43, there is a gap between the inner portions 42 adjacent to each other. Therefore, compared with the case where there is no such gap, the stress acting on the base end of the opposing portion 45 can be reduced.

[0069] (9) A recessed portion 42a is provided in the inner portion 42. According to such a configuration, while arranging the inner portion 42 of the regulating member 40 between the trailing edge portion 18a of the scuff plate 18 and the first portion 33 of the weather strip body 30, the interference between the inner portion 42 and the trailing edge portion 18a can be suppressed by the recessed portion 42a provided in the inner portion 42. Therefore, it is not necessary to change the design of the scuff plate 18 due to the provision of the regulating member 40.

[0070] (10) Three regulating members 40 are provided side by side at intervals along the weather strip body 30. In order to preferably suppress the weather strip 20 from coming off the rear end panel 14, it is preferable to provide the regulating member 40 over a wide range in the extending direction of the weather strip body 30. However, in this case, there may be problems such as an increase in the size of the regulating member 40 and difficulty in assembling the weather strip 20 to the rear end panel 14.

[0071] In this regard, according to the present embodiment, three regulating members 40 are provided side by side at intervals along the weather strip body 30. Therefore, while providing the regulating member 40 over a wide range in the extending direction of the weather strip body 30, it is possible to suppress the occurrence of problems such as an increase in the size of the regulating member 40 and deterioration in the assemblability of the weather strip 20 to the rear end panel 14.

[0072] <Modification example> The present embodiment can be implemented with the following modifications. The present embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range.

[0073] · The number of the restricting members 40 is not limited to three. The number of the restricting members 40 can be two or one. Also, the number of the restricting members 40 can be four or more. · If interference with the scuff plate 18 is not a problem, the recessed portion 42a of the inner portion 42 can be omitted.

[0074] · The number of the inner portions 42 is not limited to two. The number of the inner portions 42 can be one or three or more. · If interference with the scuff plate 18 is not a problem, the opposing portion 45 may be provided over the entire clamping portion 41 in the vehicle width direction W.

[0076] · The restricting member 40 is not limited to being made of a hard resin. The restricting member 40 may be made of metal. Also, the restricting member 40 may be made of a soft resin. · The restricting member 40 can be abolished. In this case, the opposing portion 45 may be integrally formed with the weatherstrip body 30.

[0077] · The portion where the opposing portion 45 is provided is not limited to the portion extending along the lower peripheral edge of the opening 12 in the weatherstrip 20. The opposing portion 45 may be provided at the portion extending along the upper peripheral edge of the opening 12 in the weatherstrip 20. Also, the opposing portion 45 may be provided at the portion extending along the both side peripheral edges of the opening 12 in the vehicle width direction W in the weatherstrip 20.
