Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door trim structure for covering a passenger compartment side of a vehicle such as an automobile.

[0002]

2. Description of the Related Art As is well known, doors of vehicles such as automobiles are usually covered with a door trim as an interior material on the passenger compartment side. This door trim is generally manufactured by molding using a synthetic resin material, and in many cases, a door pocket is provided on the surface side (that is, the vehicle compartment side). As a structure of such a door trim, for example, Japanese Utility Model Laid-Open No. 4-134714 discloses a structure in which a door trim is vertically divided into two parts, which are assembled and then attached to a door body.

By the way, in recent years, in order to enhance the safety against a collision from the side of the vehicle, it has been considered to absorb the impact to some extent by a door trim when a collision load is applied from the side of the door. For example, in Japanese Utility Model Laid-Open No. 4-128912 and Japanese Patent Application Laid-Open No. 6-72153, a rib that projects outward from the vehicle body is integrally provided on the back side of the door trim, and a collision load from the side of the door is generated when the vehicle collides on the side. A structure is disclosed in which, when the rib acts, the rib is brought into contact with and pressed by the panel material of the door body to be deformed, thereby absorbing an impact load. Although it is not integrally molded with the door trim,
Japanese Patent Laid-Open No. 62308 proposes that a synthetic resin foam is attached to the back side of the door trim to absorb impact.

[0004]

However, when the door trim is provided with the ribs so as to absorb the impact load from the side of the door as described above, when the door trim is molded,
There is a problem in that a so-called “sink” due to the volume shrinkage that occurs in the cooling step after molding occurs on the surface side portion corresponding to the rib protruding portion, and the appearance is bad when viewed from the vehicle interior side.

Further, as a problem related to the molding of the door trim, when integrally molding the door pocket, it is necessary to install a slide mold or the like in the molding die, which makes the die structure complicated. That is, the door pocket is usually provided along the trim body in the lower part of the door trim, and is set to have an opening at the upper side. When the door pocket is formed, it is combined with the lower part of the trim body. It is usual that the pocket member that forms the door pocket is molded separately from the trim body and assembled to the trim body, but in this case, the number of parts increases and the assembly Will be troublesome. Therefore, it is desirable to integrally form this pocket member with the trim body.In this case, a vertically movable core type (so-called slide core) is used so that the molded product can be released from the mold without any trouble. ) Must be provided, and the mold structure must be complicated.

The present invention has been made in view of the above problems, and can prevent deterioration of the appearance when a rib is provided on the back side of the door trim, and also does not particularly complicate the mold structure. It is an object of the present invention to provide a door trim structure capable of integrally molding a door.

[0007]

Therefore, the present invention provides
A structure of a door trim having at least one of a door pocket provided on a front surface side of a trim main body and a rib projecting outward of a vehicle body on a rear surface side of the trim main body, the pocket member forming the door pocket, At least one of the ribs is integrally formed with the trim body while being pivotally connected to the trim body via a hinge portion, and the pocket member is rotatable about the hinge portion. The rib is mounted on the door body while being positioned on the front surface side of the trim body, while the rib is rotated around the hinge part and positioned on the back surface side of the trim body. It is a thing.

[0008]

According to the present invention, the pocket member is integrally formed with the trim body while being pivotally connected to the trim body via the hinge portion, and the trim body is provided with the trim body. When assembled to the main body, the hinge part is rotated to be positioned on the surface side of the trim main body, so that the pocket member should be integrally formed with the trim main body without using the slide core. You can That is, by this integral molding, the door pocket can be provided on the surface side of the trim body without increasing the number of parts, and in this case, the door pocket and the trim body can be formed without particularly complicating the mold structure. It can be integrally molded. Further, the rib is integrally formed with the trim body while being pivotally connected to the trim body via a hinge portion, and when the trim body is assembled to the door body, the rib is centered on the hinge portion. Since it is rotated to the position on the back side of the trim body, the so-called "sink" corresponding to the rib protruding portion is the trim when the trim body is assembled to the door body. It will be located on the back side of the main body. Therefore, the portion where the above-mentioned “sink” occurs cannot be seen from the passenger compartment side, and the appearance problem does not occur.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a front explanatory view of a door trim assembly 1 for a right front door of an automobile according to this embodiment, and FIG. 2 is a vertical cross-sectional explanatory view taken along the line AA in FIG. As shown in these figures, the door trim assembly 1 is divided into an upper trim 2 and a lower trim 3 which are vertically divided into two parts. 1, 3 are assembled as an assembly 1 and then attached to the door body 8 (see FIG. 2). The door body 8 is formed by combining a door inner panel 8a and a door outer panel 8b, and supports a door glass 9 so as to be able to move up and down. The upper trim 2 is provided with, for example, an armrest portion 4, while the lower trim 3 is provided with a speaker grill 5 at the front portion thereof, and along the lower portion of the lower trim 3 from substantially the center to the rear portion. A door pocket 6 is provided.

Further, the lower trim 3 is provided with a plurality of (for example, five in this embodiment) horizontal directions projecting outward from the vehicle body on the back side thereof in order to enhance safety against collision from the side of the vehicle. Ribs 7 (7a to 7e) are provided so that the impact can be absorbed to some extent by the door trim 3 when a collision load is applied from the side of the door during a side collision of the vehicle. . That is, when a collision load is applied from the side of the door, the ribs 7 (7a to 7e) are brought into contact with and pressed by the inner panel 8a of the door body 8 to be deformed, thereby absorbing shock. In addition, the rib 7
(7a to 7e) are provided in regions corresponding to the sides of the waist Mw of the occupant M seated on the seat S. Further, both the upper trim 2 and the lower trim 3 are made of, for example, polypropylene resin as a material and are molded by using a predetermined molding die.

In this embodiment, as shown in detail in FIGS. 3 and 4, the door pocket 6 and the rib 7 (7a to 7e) are formed.
Are formed integrally with the trim body 10 of the lower trim 3, and in this case, the ribs 7 (7a to 7a) are provided on the back surface side.
It is possible to prevent deterioration of appearance due to the provision of (e),
The pocket member 11 and the plurality of ribs 7 (7a to 7a) which form the door pocket 6 in combination with the lower portion of the lower trim body 10 so that the door pocket 6 can be integrally molded without particularly complicating the mold structure. The rib forming region 12 in which 7e) is formed is integrally formed with the lower trim body 10 while being rotatably connected to the lower trim body 10 via hinge portions 11H and 12H, respectively. ing.

That is, the pocket member 11 is connected along the lower edge of the lower trim main body 10 via the hinge portion 11H and is extended from the lower portion of the lower trim main body 10 (one point in FIG. 4). It is integrally formed with the lower trim body 10 by a chain line curve). On the other hand, the rib forming region 1
2 is connected along the upper edge of the lower trim main body 10 via a hinge portion 12H, and is extended from the upper portion of the lower trim main body 10 (see the one-dot chain line curve in FIG. 4). It is designed to be integrally formed with the main body 10.
In this molding state, the ribs 7 (7a to 7e) are located inside the vehicle body.
(In other words, it is in a state of protruding toward the inner side in the vehicle width direction).

Therefore, when molding a molded product in which the pocket member 11 and the rib forming region 12 are integrated in the lower trim body 10, the molding die (not shown) is opened and closed in the left-right direction in FIG. When integrally molding the door pocket 6, there is no need for a slide core that can slide vertically along the lower trim body 10 as in the conventional case. And the molding die is finished
After removing from (not shown), the pocket member 11 is
By rotating the hinge portion 11H in the direction of the solid line arrow in FIG. 4, it is positioned on the lower surface side of the lower trim body 10 (see the solid line curve in FIG. 4), and as shown in detail in FIG. For example, by fixing it to the lower trim body 10 by using a screw member 13, the lower trim body 10 has a lower surface side, which is opened upward along the lower trim body 10 from approximately the center to the rear portion. The door pocket 6 is formed. The hinge portions 11H and 12H are the members to be connected (that is, the lower trim body 10 and the pocket member 1).
1 or the rib forming region 12) is formed to be slightly thinner than that of the rib forming region 12), and can be bent by being rotated by about 180 degrees or more within an elastic range. Further, FIGS. 6, 7 and 8 are D in FIG.
FIG. 3 is a view showing a cross-sectional structure of the lower trim main body 10 along the −D line direction, the EE line direction, and the FF line direction, respectively.

On the other hand, the rib forming area portion 12 is removed from the mold and then rotated around the hinge portion 12H in the direction of the solid line arrow in FIG. The ribs 7 (7a to 7e) are positioned back to back, that is, in a state of protruding toward the outside of the vehicle body. As a result, a so-called “sink” is formed on the portion of the rib forming region 12 corresponding to the protruding portion of each rib 7 (7a to 7e).
Even if a volume contraction portion that occurs in the cooling step after molding occurs, this portion is located on the back surface side of the lower trim main body 10 and is not visible from the passenger compartment side.
At this time, the height of each rib 7 (7a to 7e) is set so that the distance between the tip of each rib 7 (7a to 7e) and the inner panel 8a of the door body 8 is substantially equal. ing. By setting in this way, the collision load from the side of the door is five ribs 7 (7a to 7e) during a side collision.
It becomes relatively uniform to each of the above, and the shock absorbing effect can be further enhanced.

As described above, the rib forming region 12 positioned on the back surface side of the lower trim main body 10 has the left and right sides provided on the back surface side of the lower trim main body 10, as shown in FIGS. 9 and 10. It is locked and fixed to the claw portion 15 of the. In the example of FIG. 9, the claw portions 15 are provided on each of the left and right sides of the rib forming region 12 at two upper and lower locations (that is, at a total of four locations). The lower trim main body 10 of the rib forming region 12 is fixed to the back surface side by, for example, FIG. 11 and FIG.
As shown in FIG. 2, it may be performed by screwing. In this case, protrusions 16 and 16 that project to the left and right are provided on both sides of the end of the rib formation region 12, and the holes 16h formed in the protrusions 16 are formed in the lower trim body 10.
The rib forming region 12 is fixed to the boss 17 by fitting the screw member 18 into the female screw hole 17h of the boss 17 after fitting the boss 17 provided on the back side of the boss 17. .

As described above, according to this embodiment, the pocket member 11 is rotatably connected to the lower trim main body 10 via the hinge portion 11H, and the lower trim main body 10 is rotatable. When the lower trim body 10 is integrally formed with the door body 8 and is assembled to the door body 8, the lower trim body 10 is rotated around the hinge portion 11H so as to rotate.
Since it is positioned on the front surface side of the pocket member 11 without using a slide core as in the conventional case,
Can be integrally formed with the lower trim body 10. That is, by this integral molding, the door pocket 6 can be provided on the surface side of the lower trim main body 10 without increasing the number of parts, and in this case, the door pocket 6 is not particularly complicated and the door pocket 6 is not complicated. 6 can be integrally molded with the lower trim body 10.

The rib forming region 12 in which the ribs 7 (7a-7e) are formed is rotatably connected to the lower trim body 10 via a hinge portion 12H. When the lower trim body 10 is formed integrally with the trim body 10 and is assembled to the door body 8, the hinge portion 1
Since it is rotated about 2H to be positioned on the back surface side of the lower trim body 10, the portion where a so-called "sink" corresponding to the rib protruding portion is generated is the lower trim body 10. When assembled to the door body 8, the lower trim body 1
It will be located on the back side of 0. Therefore, the above "Hike"
The part in which the problem occurs will not be seen from the passenger compartment side, and the appearance problem will not occur.

In the above embodiment, both the pocket member 11 forming the door pocket 6 and the ribs 7 (7a to 7e) for absorbing the impact at the time of side collision are provided integrally with the door trim (lower trim 3). The present invention can be effectively applied not only to such a case but also to a case where only one of the door pocket and the rib is provided. Further, it is needless to say that the present invention is not limited to the above embodiments, and various improvements and design changes can be made without departing from the scope of the invention.
