Description

The present invention relates to an assembly structure for vehicle weather strips.

Some vehicles are equipped with a back door that opens and closes a luggage compartment opening (hereinafter, the opening) that opens on the rear end surface of the vehicle body. In such vehicles, an annular weather strip is provided around the periphery of the opening to seal between the vehicle body and the back door (see, for example, Patent Document 1).

The automobile disclosed in Patent Document 1 is provided with a rear end panel that defines an opening. The rear end panel has a lower rear end panel that is located below the opening. A rear end surface portion that extends rearward is provided at the rear of the lower rear end panel. A trim member that covers the lower rear end panel is provided above the lower rear end panel.

The weatherstrip has a pair of retaining portions that form a groove into which the rear end surface is inserted, and a sealing surface portion that contacts the back door. The rear end surface is sandwiched vertically between the pair of retaining portions, thereby attaching the weatherstrip to the lower rear end panel.

JP 2004-322865 A

However, when removing luggage from the luggage compartment through the opening, the weather strip may be dragged by the luggage and come off the lower rear end panel.

The vehicle weatherstrip assembly structure for solving the above problem is applied to a vehicle equipped with a back door that opens and closes an opening on the rear end surface of the vehicle body, and is an assembly structure for vehicle weatherstrip that assembles a weatherstrip to the vehicle body that seals between the vehicle body and the back door when the back door closes the opening, and includes a rear end panel that constitutes 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, when the front-rear direction of the vehicle is defined as the front-rear direction and the side toward the center of the opening and the side away from the center on an imaginary plane perpendicular to the front-rear direction are defined as the inside and the outside, 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, and the weatherstrip has 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.

According to this configuration, when the weatherstrip tries to move rearward, the opposing portion of the weatherstrip comes into contact with the rear edge of the interior member. This prevents the weatherstrip from moving rearward. Therefore, even if the weatherstrip is dragged by luggage when removing luggage from the luggage compartment through the opening, the weatherstrip is less likely to come off the rear end panel.

In the above-mentioned vehicle weatherstrip assembly structure, it is preferable that the facing portion is provided on a portion of the weatherstrip that extends along the lower periphery of the opening, and the interior member forms a floor of the luggage compartment of the vehicle.

The portion of the weather strip that extends along the lower periphery of the opening is easily dragged by luggage when the luggage is removed from the luggage compartment through the opening.
In this regard, according to the above-mentioned configuration, the facing portion is provided on the portion of the weatherstrip that extends along the lower periphery of the opening, so that even if the weatherstrip is dragged by luggage when the luggage is removed from the luggage compartment through the opening, the weatherstrip can be appropriately prevented from coming off the rear end panel.

In the above-mentioned vehicle weatherstrip assembly structure, the weatherstrip comprises an annular weatherstrip body extending along the periphery, and a restricting member assembled to a portion of the weatherstrip body in the extending direction, and it is preferable that the weatherstrip body has the retaining portion and the sealing portion, and the restricting member has the opposing portion.

Generally, weatherstrips are formed by extrusion molding. This means that the weatherstrip has the same cross-sectional shape in the extension direction. In this case, the weatherstrip has opposing parts along the entire extension direction, along with the retaining part and sealing part that make up the weatherstrip, so there is a risk that the opposing parts may interfere with the interior components.

In this regard, according to the above configuration, the weatherstrip is composed of a weatherstrip main body and a restricting member. In other words, the restricting member having the opposing portion is configured as a separate body from the weatherstrip main body having the retaining portion and the sealing portion. This makes it possible to suppress interference between the opposing portion and the interior member.

In the above-mentioned vehicle weatherstrip assembly structure, it is preferable that the retaining 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 between the first portion and the second portion, and the restricting member has a sandwiching 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 the first portion is sandwiched between the inner portion and the outer portion.

According to this configuration, the restricting member can be attached to the weatherstrip body by a simple configuration in which the first part of the weatherstrip body is sandwiched between the inner and outer parts of the restricting member. Therefore, the restricting member can be attached to an existing weatherstrip body having a first part and a second part.

In the above-mentioned vehicle weatherstrip assembly structure, it is preferable that the restricting member is made of a material harder than the weatherstrip body.
According to this configuration, the opposing portion is less likely to deform than when the restricting member is made of the same soft material as the weatherstrip body, so that the opposing portion can effectively restrict the rearward movement of the weatherstrip.

In the above-mentioned vehicle weatherstrip assembly structure, it is preferable that a protrusion protruding toward the first portion is provided on the surface of the inner portion facing the first portion.

According to this configuration, the protrusion on the restricting member bites into the first portion of the weatherstrip body, which is made of a material softer than the restricting member. This makes it possible to prevent the first portion of the weatherstrip body from slipping out of the clamping portion of the restricting member.

In the above-mentioned vehicle weatherstrip assembly structure, it is preferable that the clamping portion extends in the extension direction of the weatherstrip body, and the opposing portion is provided at a portion of the clamping portion in the extension direction.

The interior member may have multiple ribs spaced apart from one another on its back surface to increase the rigidity of the interior member. In this case, if the opposing portion is provided over the entire extension direction of the clamping portion, there is a risk that the opposing portion will interfere with the ribs.

In this regard, according to the above-mentioned configuration, the facing portion is provided at a portion of the clamping portion in the extending direction, thereby making it possible to suppress interference between the facing portion and the rib.
In the above-mentioned vehicle weatherstrip assembly structure, it is preferable that the outer portion extends in the extension direction of the weatherstrip main body, the inner portion is provided in a plurality of portions spaced apart from each other in the extension direction of the outer portion, and the opposing portions are provided between adjacent inner portions.

When the facing portion of the weatherstrip comes into contact with the rear edge of the interior member, a load acts on the facing portion from the rear edge in the forward direction, which tends to cause stress to concentrate on the base end of the facing portion.
In this regard, according to the above configuration, a gap exists between adjacent inner parts in the portion where the facing parts are provided in the extension direction of the outer part, so that the stress acting on the base ends of the facing parts can be reduced compared to the case where there is no such gap.

In the above-mentioned vehicle weatherstrip assembly structure, it is preferable that a recess is provided on a surface of the inner portion facing the rear edge portion of the interior member.
According to this configuration, even though the inner portion of the restricting member is disposed between the rear edge portion of the interior member and the first portion of the weatherstrip body, the recess provided in the inner portion can suppress interference between the inner portion and the rear edge portion. Therefore, it is not necessary to change the design of the interior member due to the provision of the restricting member.

In the above-mentioned vehicle weatherstrip assembly structure, it is preferable that the restricting members are arranged in a row at intervals in the extension direction of the weatherstrip body.

To effectively prevent the weatherstrip from coming off the rear end panel, it is preferable to provide a restricting member over a wide range in the extension direction of the weatherstrip body. However, in this case, problems may arise such as the restricting member becoming larger in size and making it difficult to assemble the weatherstrip to the rear end panel.

In this regard, according to the above configuration, multiple restricting members are arranged side by side at intervals in the extension direction of the weatherstrip body. Therefore, even if the restricting members are arranged over a wide range in the extension direction of the weatherstrip body, problems such as an increase in the size of the restricting members and a deterioration in the ease of assembling the weatherstrip to the rear end panel can be suppressed.

The present invention can prevent the weather strip from coming off the rear end panel.

The scuff plate 18 corresponds to an interior member according to the present invention.
Next, the operation of this embodiment will be described.
When the weatherstrip 20 attempts to move rearward, the opposing portion 45 comes into contact with the rear edge portion 18a of the scuff plate 18. This prevents the weatherstrip 20 from moving rearward. Therefore, even if the weatherstrip 20 is dragged by luggage when the luggage is removed from the luggage compartment 11 through the opening 12, the weatherstrip 20 can be prevented from coming off the rear end panel 14.

The effects of this embodiment will be described.
(1) The assembly structure of a weatherstrip for a vehicle includes a rear end panel 14 that defines an opening 12, a weatherstrip 20 that extends along a peripheral edge 12a of the opening 12, and a scuff plate 18 that extends in the fore-aft 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 rear edge portion 18a that protrudes downward. The weatherstrip 20 includes a retaining portion 31 that retains the protruding portion 17, a facing portion 45 that faces the rear edge portion 18a in the fore-aft direction L in front of the rear edge portion 18a, and a sealing portion 32 that contacts the back door 50.

With this configuration, the above-mentioned effect is achieved, and therefore the weather strip 20 can be prevented from coming off the rear end panel 14.
(2) The opposing portion 45 is provided on the portion of the weather strip 20 that extends along the lower peripheral edge of the opening 12 .

The portion of the weather strip 20 that extends along the lower periphery of the opening 12 is likely to be dragged by luggage when the luggage is removed from the luggage compartment 11 through the opening 12 .
In this regard, according to the above-described configuration, the facing portion 45 is provided on the portion of the weatherstripping 20 that extends along the lower periphery of the opening 12. Therefore, even if the weatherstripping 20 is dragged by luggage when the luggage is removed from the luggage compartment 11 through the opening 12, it is possible to appropriately prevent the weatherstripping 20 from coming off the rear end panel 14.

(3) The weatherstrip 20 is composed of the weatherstrip body 30 having the retaining portion 31 and the sealing portion 32 , and the restricting member 40 having the opposing portion 45 .
The weatherstrip 20 has the same cross-sectional shape in the extension direction. In this case, the opposing portion 45 is provided over the entire extension direction of the weatherstrip 20 together with the retaining portion 31 and the sealing portion 32 that constitute the weatherstrip 20, so there is a risk that the opposing portion 45 will interfere with the scuff plate 18.

In this regard, according to the above configuration, the weatherstrip 20 is composed of the weatherstrip main body 30 and the restricting member 40. In other words, the restricting member 40 having the facing portion 45 is configured as a separate body from the weatherstrip main body 30 having the retaining portion 31 and the sealing portion 32. This makes it possible to suppress interference between the facing portion 45 and the scuff plate 18.

(4) The holding portion 31 holds the protruding portion 17 between the first portion 33 and the second portion 34. The restricting member 40 holds the first portion 33 between the inner portion 42 and the outer portion 43.
According to this configuration, the restricting member 40 can be assembled to the weatherstrip main body 30 by a simple configuration in which the first portion 33 of the weatherstrip main body 30 is sandwiched between the inner portion 42 and the outer portion 43 of the restricting member 40. Therefore, the restricting member 40 can be assembled to an existing weatherstrip main body 30 having the first portion 33 and the second portion 34.

(5) The restricting member 40 is made of a material that is harder than the weatherstrip body 30 .
With this configuration, the opposing portion 45 is less likely to deform than when the restricting member 40 is made of a soft material similar to that of the weatherstrip body 30. As a result, the opposing portion 45 can effectively restrict the rearward movement of the weatherstrip 20.

(6) The inner portion 42 is provided with a protrusion 42b.
According to this configuration, the protrusion 42b bites into the first portion 33 of the weatherstrip main body 30 which is made of a softer material than the restricting member 40. This makes it possible to prevent the first portion 33 of the weatherstrip main body 30 from slipping out of the clamping portion 41 of the restricting member 40.

(7) The clamping portion 41 extends in the extension direction of the weatherstrip body 30. The facing portion 45 is provided at a portion of the clamping portion 41 in the extension direction.
A plurality of ribs may be provided at intervals on the rear surface of the scuff plate 18 to increase the rigidity of the scuff plate 18. In this case, if the facing portion 45 is provided over the entire extension direction of the clamping portion 41, there is a risk that the facing portion 45 may interfere with the ribs.

In this regard, according to the present embodiment, the facing portion 45 is provided at a portion in the extending direction of the clamping portion 41. This makes it possible to suppress interference between the facing portion 45 and the rib.
(8) The facing portions 45 are provided between the adjacent inner portions 42 .

When the facing portion 45 of the weatherstrip 20 comes into contact with the rear edge portion 18a of the scuff plate 18, a forward load acts from the rear edge portion 18a to the facing portion 45. This makes it easy for stress to concentrate at the base end of the facing portion 45.

In this regard, according to the above configuration, in the portion where the facing portion 45 is provided in the extension direction of the outer portion 43, there is a gap between adjacent inner portions 42. Therefore, the stress acting on the base end of the facing portion 45 can be reduced compared to when there is no such gap.

(9) The inner portion 42 has a recess 42a.
According to this configuration, even though the inner portion 42 of the restricting member 40 is disposed between the rear edge portion 18a of the scuff plate 18 and the first portion 33 of the weatherstrip body 30, the recessed portion 42a provided in the inner portion 42 can suppress interference between the inner portion 42 and the rear edge portion 18a. Therefore, it is not necessary to change the design of the scuff plate 18 due to the provision of the restricting member 40.

(10) The three restricting members 40 are provided along the weatherstrip body 30 and spaced apart from one another.
In order to suitably prevent the weatherstrip 20 from coming off the rear end panel 14, it is preferable to provide the restricting member 40 over a wide range in the extension direction of the weatherstrip main body 30. In this case, however, problems may arise such as the size of the restricting member 40 becoming large and the weatherstrip 20 becoming difficult to assemble to the rear end panel 14.

In this regard, according to the present embodiment, three restricting members 40 are arranged side by side at intervals along the weatherstrip body 30. Therefore, even if the restricting members 40 are arranged over a wide range in the extension direction of the weatherstrip body 30, problems such as an increase in the size of the restricting members 40 and a deterioration in the ease of assembly of the weatherstrip 20 to the rear end panel 14 can be suppressed.

The number of the inner portions 42 is not limited to two. The number of the inner portions 42 may be one or three or more.
If interference with the scuff plate 18 does not become an issue, the opposing portion 45 may be provided over the entire clamping portion 41 in the vehicle width direction W. Furthermore, a plurality of opposing portions 45 may be provided at intervals from each other in the vehicle width direction W.

The protrusion 42b is not limited to being provided at the center of the inner portion 42 in the vehicle width direction W. The protrusion 42b may be provided over the entire inner portion 42 in the vehicle width direction W. In addition, multiple protrusions 42b may be provided at intervals from each other in the vehicle width direction W. In addition, the protrusion 42b may be omitted.

The restricting member 40 is not limited to being made of hard resin. The restricting member 40 may be made of metal. The restricting member 40 may be made of soft resin.
The restricting member 40 may be eliminated. In this case, the facing portion 45 may be integrally formed with the weatherstrip body 30.

The portion where the facing portion 45 is provided is not limited to the portion of the weatherstrip 20 that extends along the lower periphery of the opening 12. The facing portion 45 may be provided on the portion of the weatherstrip 20 that extends along the upper periphery of the opening 12. The facing portion 45 may also be provided on the portion of the weatherstrip 20 that extends along both side peripheries of the opening 12 in the vehicle width direction W. Even in these cases, the same effect as effect (1) of the above embodiment can be achieved.
