Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a headlining mounting structure.
[0002]
[Prior art]
A headlining formed of a flexible member is assembled on the ceiling of the automobile (vehicle), and the ceiling surface is decorated.
[0003]
Usually, this headlining is attached to a roof panel of an automobile (vehicle) through a pad material that provides various effects such as sound insulation, heat insulation, and vibration control. Specifically, for mounting the headlining, for example, a plate-like roof pad is directly attached to the entire interior of the roof panel while the body (car body) is transporting the assembly line of the car, using an adhesive or double-sided tape. After that, the head lining is assembled so as to press the roof pad against the back surface of the roof pad, and the ceiling of the body, that is, the entire indoor side of the roof panel is covered with the head lining.
[0004]
However, in such an attachment structure, the assembly parts in the assembly line are two parts (roof pad, head lining), so that there is a difficulty in workability related to the assembly.
[0005]
Therefore, recently, the headlining and the roof pad are integrated and assembled as one module part on the roof panel of the body.
[0006]
By the way, the head lining assembled to the body may be removed when wiring is provided between the roof panel and the head line or when the room lamp is repaired.
[0007]
For this reason, even if the head lining and the roof pad are assembled, it is required to be able to remove the head lining by replacement work or the like.
[0008]
Therefore, a headlining having holding rods on both sides in the vehicle width direction as shown in Japanese Patent Laid-Open No. 1-282051 is used, and a roof pad is fixed to the upper surface side of the headlining, and the two are integrated. When assembling by using a structure that assembles the headlining to the inner surface of the roof panel by engaging the modularized headlining holding rod with the engagement base formed on the roof side rail. Requires only one module part, and the head lining can be removed by releasing the engagement between the holding bar and the engagement base, or the head lining as disclosed in Japanese Patent Laid-Open No. 1-282054. A roof pad formed of a member that can be torn by external force is attached to the upper surface side, and both are integrated into one module. When the headlining is removed by applying a structure in which the top surface of this modularized roof pad is fixed to the inner surface of the roof panel with an adhesive, and the headlining is given a force in the direction away from the roof panel. A technique has been proposed in which the roof pad is torn and the headlining can be removed.
[0009]
[Problems to be solved by the invention]
Incidentally, since the head lining is a decorative member exposed in the vehicle interior, it is required to have a good appearance, and in order to ensure maintainability, it is required that the head lining can be easily attached and detached.
[0010]
However, the mounting structure of the head lining described above is a structure in which the pad material and the head lining are integrated and attached to the roof panel. Therefore, the line assembly part is certainly one part, and the workability when assembling to the body is good. However, in the former mounting structure, since the weight (load) of the pad material is applied to the head lining, the assembled head lining is easily deformed, and the appearance is liable to deteriorate due to the generated unevenness and wrinkles. In the latter mounting structure, once the headlining installed on the roof panel is removed, the torn pad material remains on both the roof panel and the headlining. It is difficult to assemble the headlining and the maintainability is poor.
[0011]
The present invention has been made by paying attention to the above circumstances, and the object of the present invention is not only modularization for improving the mountability of attaching the headlining to the roof panel, but also improving the appearance and detachability of the headlining. It is an object of the present invention to provide a headlining attachment structure.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the head lining mounting structure according to claim 1, wherein the pad material is detachably attached to the head lining by the engaging means, and the pad material integrated with the head lining by this engagement is attached. It is attached to the roof panel by the attaching means , and the engaging means has a hook portion on one of the head lining and the pad material, and has an engaging portion that engages and disengages with the hook portion on the other, and these hook portion and engaging portion Thus, when the head lining is displaced laterally from the state in which the pad material integrated with the head lining is attached to the roof panel, the engagement with the pad material is released .
[0013]
With this structure, since one component in which the pad material and the head lining are integrated (module) is assembled as a line assembly component on the roof panel, workability on the assembly line of the vehicle is improved. In addition, since the pad material is attached to the roof panel and the load of the pad material is not applied to the head lining, deformation of the head lining due to the weight of the pad material is suppressed, and the appearance of the head lining is kept good.
[0014]
In addition, after removing the head lining after assembling the head lining to the roof panel, by releasing the engagement with the pad material, only the head lining can be detached from the pad material and removed from the roof panel. When returning the head lining, it is only necessary to re-engage the head lining with the pad material, and the head lining can be easily attached and detached.
[0015]
Preferably, the pad material is bonded (fixed) to the roof panel with an adhesive, an adhesive tape, or the like, so that good sound insulation and vibration control can be obtained.
[0016]
In the head lining mounting structure according to claim 2, the hook includes: a shaft portion provided to project from the head lining; and an engagement plate piece provided at a projecting end of the shaft portion and having a larger diameter than the shaft portion. And a large-diameter portion provided in the pad material through which the engaging plate piece can be inserted, and a small-diameter portion communicating with the large-diameter portion through which the engaging plate piece cannot be inserted. It comprised from the long hole-shaped engaging part which can latch a piece.
[0017]
With this structure, when the head lining and the pad material are engaged, the hook lining plate is inserted into the large diameter portion of the engaging portion, and then the head lining is engaged so that the hook portion engages with the small diameter portion. Since it is only necessary to slide it and to reverse it, only the head lining can be easily detached from the pad material with a simple structure.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on an embodiment shown in FIGS.
[0019]
In FIG. 1, reference numeral 1 denotes a vehicle body. The lower surface (inside the room) of the roof panel 2 constituting the vehicle body 1 is provided with a pad material having sound insulation, heat insulation and vibration control effects, for example, a plate-like roof pad 3 formed of a urethane foam member. A head lining 4 formed of a flexible member is attached to cover the entire ceiling in the vehicle interior.
[0020]
The present invention is applied to the mounting structure of the headlining 4. The detailed structure of this mounting structure is shown in FIGS.
[0021]
The same structure will be described. As shown in FIG. 3B, engaging pieces 10 serving as hook portions are attached to respective portions on the back surface of the head lining 4, for example, at four points near the corner portion. In any case, the engaging piece 10 is formed at a short shaft portion 11 (E≈T) having a total length substantially the same as the thickness of the roof pad 3 and both ends of the coaxial portion 11 as shown in FIG. A disk portion 12 (corresponding to an engagement plate piece) is formed. The shaft portion 11 has a small diameter, and the disc portion 12 has a larger diameter (φC> φD). Then, one of the disk portions 12 is bonded to the back surface of the head lining 4 by a bonding method that matches the base material forming the head lining 4, for example, ultrasonic bonding, hot melt, caulking by heat, or driving in the chinskin. Thus, the engaging piece 10 is fixed in a standing state.
[0022]
The roof pad 3 has an external shape that covers, for example, substantially the entire lower surface of the roof panel 2. As shown in FIG. 3A, the roof pad 3 is detachably fixed using the engagement piece 10 so as to overlap the upper surface of the lining 4, and the roof pad 3 and the head lining 4 are integrated. Yes.
[0023]
That is, an engagement portion that can be engaged with and disengaged from the engagement piece 10, for example, an engagement hole 13, is formed in a portion near the corner portion of each roof pad 3 corresponding to each engagement piece 10. These engagement holes 13 are each formed from a long hole extending in the longitudinal direction of the vehicle body as shown in FIG. 5, for example. Specifically, the long hole is formed, for example, in a through-hole portion 14 (large diameter) formed with a large-diameter circle having a diameter that allows the disc portion 12 of the engagement piece 10 to pass through on the rear side in the longitudinal direction of the vehicle body. (ΦC <φB) is formed, and a small diameter smaller than the diameter dimension of the disk part 12 is larger than the diameter dimension of the shaft part 11 of the engagement piece 10 on the front side at a predetermined distance from the through hole part 14. A through-hole portion 15 (corresponding to a small diameter portion) (φD ≦ φA <φC) formed by a circle is formed, and the through-hole portions 14 and 15 are formed from conical long holes communicated by the relay hole portion 16. It is. In other words, the long hole has a shape in which the engagement piece 10 can freely enter and exit at the point of the through-hole portion 14 and the engagement piece 10 is regulated at the point of the through-hole portion 15.
[0024]
With this long hole structure, the disc part 12 at the tip of each engagement piece 10 is passed through the through hole part 14 of each long hole, and the roof pad 3 is overlaid on the upper surface (back surface) of the head lining 4. The head lining 4 and the roof pad 3 are shifted in the front-rear direction, and each penetrating disk 12 is moved from the relay hole 16 to the small-diameter through-hole 15 to contact the roof panel 2 and the roof pad 3. When positioned in the gap provided on the surface, the disc portion 12 of the engagement piece 10 and the opening edge of the small-diameter through-hole portion 15 are engaged as shown in FIG. 4 and FIG. As shown in FIG. 3A, when the roof pad 3 is fixed on the upper surface of the head lining 4 while being fixed, and the disk portion 12 is moved from the through hole portion 15 to the through hole portion 14 on the contrary, As shown in 7 (b), the fixation of both is released and the headlining And a roof pad 3 are also available separation. That is, the roof pad 3 is detachably attached to the head lining 4 by a combination of the engagement piece 10 and the engagement hole 13 (corresponding to the engagement means). The engaging portion may be not a long hole but a long hole-like groove, that is, a long groove formed by combining large and small circles. By attaching the roof pad 3 to the head lining 4 in this way, the head lining 4 and the roof pad 3 are integrated to form a module, that is, one head lining component. In addition, a concave portion 15a (shown only in FIG. 7) in which the disc portion 12 is fitted is formed on the opening peripheral edge of the small-diameter through-hole portion 15 so as to be easily engaged with the disc portion 12 of the engaging piece 10. It is.
[0025]
The top surface of the roof pad 3 integrated with the head lining 4, specifically, the roof pad 3 excluding the periphery of each engagement hole 13 as shown by the hatched portion of the two-dot chain line in FIG. The upper surface portion is fixed to the lower surface (inside the room) of the roof panel 2 with an adhesive 17 (or double-sided tape or the like: corresponding to attachment means), so that the vehicle body 1 flowing through the assembly line of the automobile as shown in FIG. A head lining 4 is assembled to the roof panel 2 together with the roof pad 3.
[0026]
With such a head lining 4 mounting structure, when the head lining structure is assembled, the line assembly component becomes one component, so the workability on the assembly line is good. Moreover, since the roof pad 3 is fixed to the roof panel 2 and the load of the roof pad 3 is not applied to the head lining 4, the head lining 4 is not deformed by the weight of the pad 3, and the assembled head The appearance of the lining 4 is kept good.
[0027]
Moreover, with the same mounting structure, it is easy to remove or reattach the headlining 4 after assembling the headlining 4.
[0028]
That is, for example, when the wiring (not shown) is provided between the roof panel 3 and the head lining 4 or the room lamp (not shown) is repaired, the assembled head lining 4 is once removed. In this case, first, from the state where the headlining 4 shown in FIG. 7A is assembled to the roof panel 2, for example, an external force is applied to the entire headlining 4 so as to be displaced rearward in the vehicle body front-rear direction.
[0029]
At this time, since each engaging piece 10 is only engaged with each through hole 15 of the roof pad 3 fixed to the roof panel 2, the head lining 4 is slid backward by an external force applied. To do.
[0030]
In accordance with this displacement, each engagement piece 10 is guided from the small diameter through hole 15 to the large diameter through hole 14 as shown in FIG.
[0031]
Here, since the through hole portion 14 is formed to have a larger diameter than the portion having the largest outer shape of the engagement piece 10, that is, the disc portion 12, each engagement piece 10 is positioned to each through hole portion 14. Then, the engagement piece 10 and the engagement hole 13 are disengaged.
[0032]
Accordingly, by pulling the head lining 4 downward as it is, only the head lining 4 is detached from the roof pad 3 fixed to the roof panel 2 and can be detached from the roof panel 2 as shown in FIG.
[0033]
Further, when the head lining 4 is returned, after inserting each engaging piece 10 of the head lining 4 into the through hole 14, for example, the whole head lining 4 is slid forward in the vehicle body front-rear direction, and each engaging piece 10 is moved. Positioning from the large-diameter through hole 14 to the small-diameter through hole 15 and engaging with the roof pad 3 is easy even when the headlining 4 is repeatedly attached and detached. Thereby, maintainability is excellent.
[0034]
In addition, the roof pad 3 is bonded to the roof panel 2 with an adhesive 17 (or double-sided tape or the like), and the roof pad 3 and the head lining 4 are engaged with and disengaged from the engagement piece 10 (hook portion) and the engagement piece 10. Since the ellipse engaging hole 13 (engaging portion) is attached so as to be detachable, only the headlining 4 can be easily attached and detached with a simple structure.
[0035]
In one embodiment, the hook portion is formed on the head lining and the engaging portion is formed on the pad material. However, the present invention is not limited to this, and the hook portion is formed on the pad material and the head lining is engaged with and disengaged from the hook portion. A joint may be formed. Of course, the hook part may be other parts instead of the engaging piece, and the engaging part may be other engaging parts instead of the long hole or the long groove.
[0036]
【The invention's effect】
As described above, according to the invention described in claim 1, the pad material and the head lining are modularized (integrated) and attached to the roof panel. Therefore, the workability of the line assembly is good.
[0037]
Moreover, since the pad material is attached to the roof panel, the head lining need not be loaded with the pad material, deformation of the head lining is suppressed, and a good appearance can be maintained.
[0038]
In addition, since the pad material and the head lining are detachably attached, even if the head lining may be removed for convenience after the assembly, the head lining can be easily released by simply releasing the engagement. Only the lining can be removed, or the head lining can be reattached to the roof panel again, providing excellent detachability and improving maintainability.
[0039]
According to the second aspect of the present invention, the engaging means is composed of a hook portion protruding from the head lining and an elongated hole-like engaging portion provided in the pad material, and the head lining and the pad. When engaging the material, the hook part is inserted into the large-diameter part of the engaging part, and then the head lining is slid so that the hook part engages with the small-diameter part. Can be easily detached from the pad material.
