Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile insulator dash attached to a dash panel in a vehicle compartment, and more particularly to an automobile insulator dash that enables smooth adjustment work such as height adjustment of pedals. .

[0002]

2. Description of the Related Art For example, as shown in FIG. 10, on a side surface of a dash panel 1 which divides an engine room E and a vehicle compartment R, noise is propagated from the engine room E into the vehicle compartment R. An insulator dash 2 is installed to prevent this.

The insulator dash 2 includes a sound insulating material layer 3 such as a vinyl chloride sheet or a rubber sheet mixed with a filler,
A laminated structure with a sound absorbing material layer 4 made of a porous base material such as felt or polyurethane foam, which is lined and integrated on the back surface side, is generally known.

Incidentally, in order to reduce the cost and reduce the weight, recently, a molding felt is often used as the sound absorbing material layer 4.

By the way, this insulator dash 2
Various pedals, such as brake pedals and accelerator pedals, are set in the dash panel 1 in which is installed, and through holes are formed at corresponding positions of the insulator dash 2 in order to penetrate these pedals. ,
Actually, the height adjustment of various pedals is performed after the insulator dash 2 is attached to the dash panel 1.

For example, in order to adjust the pedal height of the brake pedal, as shown in FIG. 11, a slit 5 having a substantially U-shape is formed at a position near the pedal of the insulator dash 2.
The lid 5a defined by the slit 5 is rolled up to expose the dash panel 1 surface, as shown in FIG. The magnet 7 which is set in the measuring instrument 6 and is embedded in the measuring instrument 6
Thus, the inspection is performed with the measuring instrument 6 fixed to the dash panel 1.

[0007]

However, in the conventional insulator dash 2, as shown in FIG. 13, when the lid 5a is rolled up and the measuring jig 6 is set, the slit 5 is the same as that of the insulator dash 2. Since it is located on the surface, it is difficult to insert a finger, and the lid 5a
Is a major factor that reduces the workability of the opening operation work.

Furthermore, the thickness of the sound absorbing material layer 4 is 20 to 30 mm.
It has been pointed out that when the felt is thick and the felt is used, it is difficult to perform the cutting work because of lack of rigidity in the cutting work for forming the slits 5, and the cutting work is difficult. The actual situation is that they are entangled and hinder the smooth opening operation of the lid 5a.

The present invention has been made in view of the above circumstances, and is an automobile insulator dash including a sound insulating material layer and a sound absorbing material layer, which are attached to the interior side of the dash panel, and are substantially U-shaped. The opening of the lid partitioned by the slits is used to set the measuring instrument, and the smooth opening operation of the lid can be expected in the insulator dash for automobiles, and the measurement work such as adjusting the height of the pedal will proceed smoothly. The first object is to provide an automotive vehicle insulator dash.

A second object of the present invention is to provide an insulator dash for an automobile, which can easily perform a slitting work to be opened in the insulator dash for setting a measuring instrument.

[0011]

In order to achieve the above object, the present invention comprises a laminated body of a sound insulating material layer and a sound absorbing material layer which are additionally provided on the interior side of a dash panel. A slit having a substantially U-shape is opened below, and by opening the lid formed by the slit, a measuring instrument is set on the dash panel surface. Alternatively, a lid operation space is set between the dash panel and the sound absorbing material layer along the entire circumference.

Further, according to the present invention, the sound absorbing material layer is made flat and thin along a part or the entire circumference of the slit, and a space for lid operation is provided between the sound absorbing material layer and the dash panel. It is characterized by being set.

Further, according to the present invention, since the embossed portion projecting toward the room is formed along a part or the entire circumference of the slit, a space for lid operation is provided between the dash panel and the sound absorbing material layer. Is set.

[0014]

[Function] As is apparent from the above structure, since the lid operation space is set between the dash panel and the sound absorbing material layer along a part or the whole circumference of the slit, the slit is directed downward. By pressing the button, a step is formed between the insulator dash body and the lid, and it becomes easy to insert a finger, and the lid opening operation can be performed easily and quickly.

Further, by flattening the sound absorbing material layer in the region where the space for operating the lid is set by compression, the entanglement of the fibrous elements on the main body side and the lid side can be suppressed through the slit, and the opening operation of the lid can be performed easily and quickly. Can be done.

Furthermore, if the compression is flattened along the entire circumference of the slit, the rigidity of the sound absorbing material layer is enhanced, so that a smooth cutting operation can be performed.

First, a first embodiment of an automobile insulator dash according to the present invention will be described with reference to FIGS. 1 to 4.

1 to 3, an automobile insulator dash 10 according to the present invention comprises a sound insulating material layer 11 having a relatively high surface density such as a vinyl chloride sheet and a rubber sheet, and a sound absorbing material layer 12 made of molded felt. It is composed of structures.

More specifically, the sound insulation material layer 11 is made of a vinyl chloride sheet, the sound absorption material layer 12 is made of molding felt, and the sound insulation material layer 11 and the sound absorption material layer 12 are separately molded by cold press molding. After being molded into a required shape with a pressure-bonding mold, the both are integrally molded through an adhesive. The sound insulation material layer 11 has a thickness of 3 to 5 mm, and the sound absorption material layer 12 has a thickness required to absorb sound. 20-30 in lower part
Areas such as mm and mounting parts that require relatively high rigidity are set to around 5 mm.

By the way, the insulator dash 10 is provided with a plurality of through holes for allowing various pedals, wiring harnesses, etc. to penetrate therethrough. Particularly, below the through holes for the brake pedal, In order to install a measuring instrument for adjusting the pedal height of the brake pedal, a substantially U-shaped slit 13 is opened, and the lid 14 partitioned by the slit 13 is opened in the arrow direction in FIG. To form the opening 15 by
Through this opening 15, as shown in FIG. 4, a measuring instrument 30 is set on the surface of the dash panel 20.

A feature of the present invention is that the edge of the lid 14 can be easily caught by a finger so that the opening operation of the lid 14 can be smoothly performed.

That is, in this embodiment, the slit 13
A step line 16 is set along the slightly outer side of the slit 13 to cover not only the rear surface of the slit 13 but also the rear surface of the lid 14.
A lid operating space 17 is set between the sound absorbing material layer 12 and the dash panel 20.

In the case of the present embodiment, the thickness of the sound absorbing material layer 12 in the insulator dash 10 is set to 5 mm, while the thickness of the sound absorbing material layer 12a divided by the step line 16 is set to 5 mm, while the thickness of the general portion in the toe board portion is 15 mm. Has been done.

Therefore, as shown in FIG. 3, if the outside of the slit 13 is pressed downward, the insulator dash 10 is easily deformed by the space 17 for operating the lid, and the finger is easily engaged with the edge portion of the lid 14. The lid 14 can be stopped and the lid 14 can be quickly opened.

Further, as the second feature of this embodiment,
That is, the sound absorbing material layer 12 at the location where the slit 13 is formed is set to a thin portion.

That is, in comparison with the workability of cutting and cutting the felt of 15 to 30 mm, if the thickness is 5 mm, the compression flattening is made 3 to 6 times, and the rigidity is enhanced accordingly, so that the slit 13 has The workability at the time of cutting is improved, and the lid 14 passes through the slit 13.
Since the fibers between the side and the main body are less likely to be entangled with each other, the cut workability in the slit 13 is improved and the entanglement of the fibers is prevented, so that a smoother opening operability of the lid 14 can be expected. There are advantages.

Next, a second embodiment of the present invention will be described with reference to FIGS.

The description of the same parts as in the first embodiment will be omitted.

In this embodiment as well, a smooth opening operation of the lid 14 is achieved by setting the lid operation space 17, which is the same as in the first embodiment. However, in the case of the present embodiment, this lid operation is performed. When the space 17 for a vehicle cannot be effectively secured, for example, the insulator dash 10
Even if the outer side of the slit 13 is pressed downward, the edge of the lid 14 may be pressed even if the outer side of the slit 13 is constrained due to the thickness of the sound absorbing material layer 12 being constrained due to the relationship with the counterpart component. This is effective when the space for inserting the finger cannot be set.

That is, the embossed portion 18 projecting toward the vehicle interior is formed in a part of the slit 13, and the embossed portion 18 is formed.
The lid operating space 17a is set below.

In the case of this embodiment, even if the product thickness of the insulator dash 10 and the original thickness of the sound absorbing material layer 12 are thin, the lid operating space 17 having an effective depth is obtained.
There is an advantage that a can be secured and smooth workability can be expected in the operation of opening the lid 14.

Next, FIGS. 7 to 9 show various modifications of the insulator dash 10 for an automobile according to the present invention. In the embodiment of FIG. 7, a compression flat portion is set in the sound absorbing material layer 12. Instead, a part of the slit 13 or along the slit 13 is provided with an embossed portion 18 projecting toward the vehicle interior side on both the sound insulating material layer 11 and the sound absorbing material layer 12, and the space between the dash panel 20 and the sound absorbing material layer 20 is formed. In addition, the lid operation space 17 is set.

In this embodiment, the lid operating space 1
By using 7, the operation and effect of enhancing the opening operability of the lid 14 is provided, but since the sound absorbing material layer 12 is not configured to be compression flat, the cut workability of the slit 13 and the like are slightly inferior. There is an advantage in that the sound absorption performance at the place where the lid 14 is set is kept good, and it is possible to appropriately select the aforementioned embodiment or this embodiment in consideration of the required sound absorption performance and the like.

Further, as shown in FIG. 8, the compression-flattened sound absorbing material layer 12a is set along a part or the entire circumference of the slit 13 so that the lid operating space 1
7 may be set.

In this case, since the sound absorbing material layer 12 having the same thickness as that of the general portion is located on the rear surface of the lid 14, this embodiment also has the effect of improving the sound absorbing performance at the place where the lid 14 is set.

Next, the embodiment shown in FIG.
The step portion 19 is formed on a part of the edge of the lid, and the lid operation space 17 is provided below the step portion 19. If the outside of the slit 13 is pressed downward, the lid operation space 17 By inserting a finger into the space 17 and putting the finger on the edge of the lid 14, the opening operation of the lid 14 can be performed easily and smoothly.

As described above, the present invention can have various variations by the above-mentioned embodiments,
Basically, if a lid operating space 17 is set between the rear surface of the sound absorbing material layer 12 and the dash panel 20 along a part or the entire circumference of the slit 13, the sound absorbing material layer 12 is compressed and flattened. Parts may or may not be set.

[0042]

As described above, the vehicle insulator dash according to the present invention has the following special operational effects.

(1) In the case where a U-shaped slit formed in the insulator dash is set to provide an opening for installing a measuring instrument such as a pedal height adjusting instrument, part or all of the slit is set. Since the space for lid operation is set between the dash panel and the sound absorbing material layer along the circumference, if the outside of the slit is pressed downward, it will be located on the back side of the edge of the lid. This has the advantages that a finger can be easily inserted, a smooth opening operation of the lid can be expected, and a measuring instrument such as a pedal height adjusting instrument can be easily installed.

(2) According to the second aspect of the invention, the sound absorbing material layer is flattened along the slit so as to set a space for lid operation between the back surface of the sound absorbing material layer and the dash panel. Since it is a structure that is easy to insert a finger, there is no entanglement between fibrous materials, and the rigidity of the cut part is strengthened, so a smoother opening operation of the lid can be expected, This has the effect of improving the cut workability of the slit.
