Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for attaching automotive interior materials such as mats, dowel linings, inner wall linings, etc. to an automobile body through insulators such as cushioning materials, soundproofing materials, and heat insulating materials.

Figures 1 and 2 of Utility Model Publication No. 56-24141 have already been proposed as mounting structures for automobile interior materials.
There is one shown in the figure.

In the example shown in Fig. 1, an insulator b is screwed to a vehicle body a, and a piece of hook-and-loop fastener (product name: Magic tape) is attached to an appropriate location on the insulator b.
At the same time, the other piece m' of the hook-and-loop fastener is sewn to the back side of the interior material c that corresponds to the above piece m, and both pieces m and m' are engaged by crimping to attach the interior material c to the vehicle body. Ta.

In the case shown in Fig. 1, the fixing force of the surface fastener is weak and the interior material easily comes off.
Since a pair of hook-and-loop fasteners must be attached to both the interior material and the insulator, there are disadvantages in that the number of installation steps increases and the cost of materials increases, resulting in high costs.

In the example shown in Fig. 2, instead of the hook-and-loop fastener, an iron clip f that passes through the insulator b is fixed to the vehicle body a by welding or the like, and a through hole g is provided in the interior material c at a location corresponding to the iron clip f. The interior material c was attached to the vehicle body a by inserting an iron clip f into the through hole g and bending the protruding portion of the clip to one side.

When using this attachment method, if the interior material is repeatedly attached and detached, there is a risk that the bent part h of the iron clip will deteriorate and break. If the clip broke, the insulator had to be removed and a new iron clip was welded to the car body, making repairs quite cumbersome.

The present invention relates to a mounting structure for automobile interior materials that has been devised to solve the above-mentioned problems, in which metal stops protruding from the inner surface of the panel through welding means are formed in parallel on the tip side. The bending stopper and the locking piece having a locking hole pass through the insulator on the inner surface of the panel, and the bending stopper is bent and placed on top of the insulator, so that the interior material is The end is penetrated by the locking piece and placed on top of the insulator, and the synthetic resin clip for securing the interior material consists of a head and a frame protruding from the back of the head. A fitting hole corresponding to the locking piece is formed at the tip of the frame, and a locking elastic piece is provided inside the frame with a claw corresponding to the locking hole, The clip is attached to the outer periphery of the locking piece from above the interior material, the fitting hole of the frame portion is relatively fitted to the locking piece, and the claw of the locking bullet piece is relatively locked to the locking hole. It is characterized by its existence, and its purpose is to
The interior material must be positioned reliably and can be held in place without shifting, structural fatigue failure will not occur even if the interior material is repeatedly attached and removed, and installation conditions that correspond to the thickness of the interior material can be obtained. The purpose of the present invention is to achieve effects such as speedy installation work and good appearance of the mounting structure.

Embodiments of the present invention will be described below with reference to FIGS. 3 to 8.

1 is a floor panel, 2 is an insulator,
3 is a stopper made of metal (iron plate), 4 is an interior material such as a carpet, and 5 is a clip made of flexible synthetic resin.

In the above, the insulator 2, which has functions such as sound insulation, heat insulation, and buffering, is attached to a predetermined portion of the inner surface of the panel 1.

As clearly shown in FIG. 5, the stopper 3 has a substantially L-shape, and a bending stopper 30 and a locking piece 32 having a locking hole 31 are formed in parallel with each other on the tip side thereof. There is.

The base end of this stopper 3 is provided to protrude from the inner surface of the panel 1 via welding means, and the tip end of the stopper 3, that is, the bending stopper piece 30 and the locking piece 32 are connected to the through hole of the insulator 2. 20, and its bending stopper 30 is bent and placed on top of the insulator 2 as shown in FIG.

In FIG. 3, the interior material 4 laid on the inner surface of the panel 1 has a through hole 40 at its end.
is penetrated by the locking piece 32 of the stopper 3, and the end of the interior material 4 is stacked on the insulator 2.

Clip 5 clearly shown in Figures 6 to 8
consists of a head 50 and a frame 51 protruding from the back surface of the head 50, and a fitting hole 52 corresponding to the locking piece 32 is formed at the tip of the frame 51. The locking hole 3 is provided in the frame portion 51.
A locking bullet piece 54 is provided on its inner surface with a plurality of claws 53 that can be freely engaged and detached from each other.

In this case, the inner surface of the entrance portion of the fitting hole 52 is an arcuate (or inclined) guiding introduction surface 55,
Further, the inner surface of the locking bullet piece 54 is continuous with the circumferential side surface of the fitting hole 52.

The clip 5 having such a structure is attached to the outer periphery of the locking piece 32 from above the interior material 4 as shown in FIG. The fitting hole 52 of 51 is relatively fitted with the locking piece 32, and the claw of the locking elastic piece 54 is inserted into the locking hole 3.
1 and is relatively locked.

In this way, the interior material 4 is held without shifting on the panel 1, and a predetermined mounting structure is obtained.

In the present invention, which can be embodied as in the above embodiment, a metal stopper 3 fixed to the panel 1 and a synthetic resin clip 5 attached to the locking piece 32 of the stopper 3 are used. The interior material 4 can be held, and at this time, the locking piece 32 and the clip 5 are relatively locked while penetrating the interior material 4, so the interior material holding force is considerably greater than that of a hook-and-loop fastener. , the interior material 4 will not come off even if a slight external force is applied.

In addition, the clip 5 made of synthetic resin can be detached from the locking piece 32 by applying a strong pulling force to it, and even if the interior material 4 is repeatedly removed by such operations and held again, the synthetic resin The clip 5 made of resin does not suffer from fatigue failure like iron clips, and retains its predetermined function over a long period of time.

Furthermore, since the installation work is only a simple fitting or light work such as bending, the work speed is such that the installation structure can be completed in a short time. etc. are completely hidden inside, making it look good on the outside and give a nice appearance.

Note that when there are multiple claws 53 of the locking bullet piece 54,
By adjusting the degree to which the pawl 53 engages with the locking hole 31, it is possible to obtain a mounting condition that corresponds to the thickness of the interior material 4, and even when there is only one pawl 53, the interior material 4 can be pressed while being pressed. By pushing the clip 5 toward the locking piece 32 and locking it, the interior material 4 within a predetermined thickness can be held.

As described above, according to the mounting structure for automotive interior materials according to the present invention, the interior materials can be positioned reliably and held without shifting, and structural fatigue failure is unlikely to occur even if the interior materials are repeatedly attached and removed. Furthermore, the installation work can be done quickly, the appearance is good, and interior materials of various sizes (thicknesses) can be installed.
