DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure of a head lining to be mounted on a ceiling of a vehicle interior.

[0002]

2. Description of the Related Art As a conventional headlining fixing structure, for example, there is one shown in FIGS. (1988
FIG. 4 is a view of the headlining 1 as viewed from the lower surface side. The headlining 1 uses a resin felt obtained by impregnating a felt with a phenol resin and hardening the core. A plurality of clips 3 are attached at predetermined intervals in the vehicle width direction on the upper surface of an edge 1a of the headlining 1 on the rear side in the vehicle longitudinal direction. As shown in FIG. 5, the clips 3 are fitted into and engaged with through holes 11 provided in the rear roof rail 9 on the roof panel side, and the edge 1a is fixed. The front edge 1b of the headlining 1 in the front-rear direction of the vehicle body is fixed together with the attachment of the sun visor 5 and the like.

The fixing of the clip 3 to the headlining 1 is as shown in FIGS. That is, the base portion 3a of the clip 3 is pressed by the clip seat 7, and the burring 7a of the clip seat 7 is driven into the headlining 1.

The removal of the head lining 1 is performed as follows. First, the sun visor 5 on the front edge 1b side
Is removed to release the fixing of the edge portion 1b. When the front edge portion 1b is lowered as it is, the terminal 1C of the head lining 1 contacts the roof panel and becomes a fulcrum, and a detaching force is applied to the clip 3 so that the entire head lining 1 can be removed.

[0005] For reference, the head lining 1 is taken out of the vehicle from the passenger seat door as shown in FIG.

[0006]

By the way, the clip 3
Is fixed by driving the burring 7a of the clip seat 7 as described above, the head lining 1 must be hard using resin felt or the like. For example, the core material is made of PPO (modified noryl). However, in the case where the weight is reduced by using such a method, there is a problem that the burring 7a cannot be driven and cannot be applied.

Further, if the clip 3 is simply inserted through the through hole 11 and fixed, the head lining 1 may vibrate due to the vibration of the vehicle body, and the clip 3 may move up and down with respect to the through hole 11 to cause a low-grade sound. For this reason, conventionally, a special inclusion, for example, urethane or the like has been inserted around the clip 3 to restrict the movement of the headlining 1 so as to prevent a low-pitched sound. However, the number of parts increases due to the special inclusions, complicating parts management and increasing costs.

On the other hand, a resin clip seat having a clip support portion is bonded to the headlining 1, and the base of the clip is engaged with the clip support portion of the clip seat by sliding insertion or the like. The material 1 is not particularly limited, and it is possible to reduce the weight by using PPO or the like. It is also very easy to integrally provide a clip seat with an abutment that abuts on the roof panel side, and this abutment restricts the relative movement of the headlining 1 with respect to the roof panel, thereby preventing low-pitched sounds. You can.

However, if the clip seat made of resin is simply adhered to the head lining 1, a problem may occur when the head lining 1 is removed. That is, when removing the head lining 1, as described above, first, the fixing of the front edge 1b is released, and then the edge 3b is lowered, thereby applying a detaching force to the clip 3. Since it also acts as a peeling force between the clip seat and the head lining 1, the head lining 1
The clip seat may be detached from the headlining 1 when removing the headliner. Further, when removing the headlining 1, the terminal 1c may be rubbed against the rear window glass or the like, which may damage the terminal 1c.

In view of the above, the present invention uses a clip seat made of resin for attaching the clip, thereby expanding the applicable range of the material of the head lining, easily preventing low-pitched sound without increasing the cost, and removing the head lining. An object of the present invention is to provide a fixing structure of a head lining which maintains strong adhesion of a clip seat at times and does not damage the head lining.

[0011]

A resin clip seat having a clip supporting portion is adhered to an upper surface of an edge portion of a head lining attached to a lower surface side of a roof panel, and an end of the roof panel is attached to the clip supporting portion. Attach a clip to be inserted into and engage with a through hole provided on the lower surface of the edge, and attach the clip to the clip seat, closer to the edge of the head lining than the clip, to the clip from the distance from the clip to the abutment. Characterized in that the length from the clip to the clip seat edge is increased on the opposite side of the contact portion with respect to.

[0012]

According to the above construction, the clip seat made of resin is adhered to the upper surface of the edge of the head lining, and the clip can be attached to the clip support portion of the clip seat.
When the clip is fitted into the through hole on the lower surface of the roof panel and the head lining is attached to the lower surface of the roof panel, the contact portion of the clip seat comes into contact with the roof panel and the head lining of the roof panel is Regulate movement. When removing the head lining, when releasing the edge of one side of the head lining and lowering the edge, and applying a detaching force to the clip on the other edge, It serves as a fulcrum and can provide a reliable detachment force to the clip. At this time, the peeling force of the adhesive to the head lining acts on the edge of the clip seat on the side opposite to the contact portion with the clip interposed. However, since the length from the clip to the clip seat edge on the opposite side of the clip from the clip to the clip is longer than the distance from the clip to the clip, the clip seat edge is compared to the release force on the clip. The peeling force acting on the substrate becomes extremely small, and a strong adhesive state can be maintained.

[0013]

Embodiments of the present invention will be described below. In addition,
The same components as those in FIGS. 4 to 7 are denoted by the same reference numerals, and the description thereof will not be repeated.

FIG. 1 is a perspective view showing a main part of a headlining fixing structure according to an embodiment of the present invention. Head lining 1 attached to the lower surface side of roof panel 13
Is composed of a skin 15 and a core material 17, and the core material 17 is formed of, for example, PPO (modified Noryl) to reduce the weight.

A resin clip seat 19 is adhesively fixed to the upper surface of the rear edge 1a of the head lining 1 in the front-rear direction of the vehicle body. The clip seat 19 made of resin is formed on a rectangular flat plate, and its longitudinal direction is fixed in the vehicle front-rear direction.

A clip supporting portion 21 is provided on one side in the longitudinal direction of the clip seat 19, that is, near the edge 1a of the head lining 1. This clip support 21 is
It has an insertion hole 25 penetrating in the longitudinal direction of the clip seat 19, and a notch 23 is provided on one side. Below the insertion hole 25, two slide guides 27 a and 27 b are provided on the surface of the clip seat 19.

On both sides of the clip support 21, four contact portions 29a, 29b, 29 higher than the clip support 21 are provided.
c, 29d are provided. This section 29a, 29b
The clip seat 19 is provided on the left and right sides in the width direction of the clip seat 19 closer to the edge 1a of the head lining 1 than the clip support portion 21, and the other abutments 29c and 29d are provided symmetrically on opposite sides of the clip support portion 21. ing. Each part 29a,
The upper surfaces of 29b, 29c, and 29d are flat contact surfaces 31a, 3
1b, 31c and 31d.

The clip 3 is inserted and fixed in the insertion hole 25 of the clip support 21. The clip 3 is made of a steel plate.
a, 27b and inserted into the insertion hole 25.
The claw 3b of the base portion 3a is engaged with the notch portion 23, and is prevented from coming off. Such a clip 3 is fitted into and engaged with a through hole 11 provided on the lower surface of the edge portion of the roof panel 13, that is, the rear roof rail 9.

FIG. 2 is a sectional view taken along the line II-II of FIG. As is apparent from FIG. 2, in the embodiment of the present invention, the contact portions 29a, 29
The length L2 from the predetermined position of the clip 3 to the clip seat edge 19a is longer on the opposite side of the abutments 29a and 29b across the clip 3 than the distance L1 to the predetermined position 9b. In this case, the predetermined position of the clip 3 is such that, for example, when the other end side of the head lining 1 is pulled down as shown by the arrow A, and when the clip 3 is released, the base 3a of the clip 3 The part which receives the force directly from is selected. That is, this part 29
a, 29b is an edge 21a on the opposite side of the clip support 21. The predetermined positions of the contact portions 29a and 29b are set when the detachment force is applied to the clip 3 as described above.
The contact portions 29a and 29b are portions that actually contact the surface of the rear roof rail 9. That is, this part 29a, 2
9b is a portion of the rear end 33.

FIG. 3 is a bottom view of the headlining 1 as viewed from below. As shown in FIG.
The four clip seats 19, to which the clips 3 are attached at predetermined intervals in the width direction, are attached to the rear edge 1a at predetermined intervals. Accordingly, the end portion 1a is fixed by the clip 3 attached to the clip seat 19. On the other hand, the front edge 1b of the headlining 1
The side is fixed together with the attachment of the sun visor 5, the room mirror 35, the room light 37 and the like. Further, the central portion of the headlining 1 is fixed together with the mounting of the room light 39.

Next, the operation will be described.

First, the clip seat 1 for supporting the clip 3
Since 9 is bonded to the headlining 1, even if the core material 17 of the headlining 1 is made of a lightweight material such as PPO, there is no problem in fixing between the clip seat 19 and the headlining 1. Therefore, the overall weight can be significantly reduced. When the clip 3 is engaged with the through hole 11, the contact portions 29a, 29b, 29c, 29
The contact surfaces 31a, 31b, 31c, 31d of d contact the lower surface of the rear roof rail 9, and a tight relationship is established between the clip 3 and the through hole 11. Therefore, the movement of the clip 3 with respect to the through hole 11 and the movement of the head lining 1 are restricted, and the generation of a low-pitched sound can be prevented. Moreover, since the contact portions 29a, 29b, 29c, and 29d are integrally molded with the clip seat 19 by resin, the number of components does not increase, component management is easy, and cost increase can be suppressed.

Further, even when the head lining 1 is removed, the adhesion between the clip seat 19 and the head lining 1 can be held firmly. That is, when removing the headlining 1, first, in FIG.
The room mirror 35, the room light 37 and the like are removed, and the fixing of the front edge 1a of the headlining 1 is released. In addition, the center room light 39 is also removed to release the fixing similarly. In this state, the front edge 1b is pulled down, and the rear edge 1a side of the head lining 1 rotates about the clip 3 as shown by the arrow A in FIG. At this time, the abutting portions 29a and 29b abut on the lower surface of the rear roof rail 9 to serve as a fulcrum, and the clip 3 is given a downward detaching force with respect to the through hole 11. Therefore, detachment of the rear edge 1a side can be easily performed. In this case, the terminals 1a of the headlining 1 are connected to the rear window glass 3
2 can be prevented from being strongly rubbed, and the terminal 1c can be protected.

On the other hand, the front edge 19a of the clip seat 19
A peeling force acts on the side. In this case, since the dimension L2 is larger than L1, the peeling force acting on the edge 19a is significantly smaller than the detaching force for the clip 3. Therefore, even when the head lining 1 is pulled down as shown by the arrow A, the strong adhesion of the clip seat 19 can be maintained.

In the above embodiment, the head lining 1
Although the description has been given of the case where the weight is reduced by using PPO, it is needless to say that the present invention can be applied to the case where the molding is made of resin felt or the like. In addition, the clip seat 19 to which the clip 3 having the above configuration is attached can be applied to a portion other than the rear edge 1a of the headlining 1.

[0026]

As is clear from the above, according to the structure of the present invention, the clip seat is adhered and fixed to the head lining, so that the material of the head lining is not limited and the applicable range can be expanded. When the clip is fitted into the through hole on the roof panel side, the contact portion abuts on the roof panel side, so that the movement of the clip and the like can be restricted to prevent the generation of low-pitched sound. In addition, since this portion can be formed integrally with the clip seat, there is no need to insert a special intervening member, so that parts management is easy and cost can be reduced. When the head lining is removed, the clip serves as a fulcrum to apply a releasing force to the clip, so that the clip can be reliably released and the head lining terminal can be prevented from being damaged. Furthermore, since the length to the edge of the clip seat is set to be long, the peeling force of the clip seat that acts when the headlining is removed is significantly smaller than the detaching force of the clip, and strong adhesion is maintained. Can be.
