JP5487471B2 - Floor mat for driver seat - Google Patents

Description

  The present invention relates to an automobile floor mat, and more particularly to a driver seat floor mat placed at the foot of a driver.

  Usually, a tufted carpet or a needle punched carpet (nonwoven fabric) is used as an interior carpet for automobiles. When a needle punch carpet is mounted for an interior of an automobile, a floor mat placed on the needle punch carpet has a main surface that has a spike shape with a thermoplastic resin or a non-woven fiber melted. A floor mat having such a back surface structure causes some slip on an interior carpet of an automobile during use. Therefore, for safety, the floor mat for the driver seat can be fixed to the vehicle body via a fixture.

  However, when a commercially available floor mat is placed on the interior carpet instead of a genuine product, the fixture may not be used. Moreover, even if it is a genuine product, the use of a fixture may be neglected. In that case, every time the driver (driver) steps on the brake, a forward force is applied to the floor mat, and the floor mat may gradually shift forward. In the worst case, it is assumed that the floor mat will enter the back of the brake pedal without the driver's knowledge and the brake will not work.

  Japanese Patent No. 4072916 discloses a floor mat that has an anti-slip effect enhanced by providing an engagement region for increasing the anti-slip effect at the tip of the back side pile yarn. With the floor mat disclosed in this publication, it becomes difficult to slip on the interior carpet without using a fixture.

Japanese Patent No. 4072916

  The floor mat disclosed in Japanese Patent No. 4072916 has a very high adhesive effect on the interior carpet. For this reason, if the floor mat is accidentally placed over the accelerator pedal without using a fixture, the back of the floor mat around the accelerator pedal will adhere strongly to the floor carpet when the accelerator pedal is depressed. It is assumed that the accelerator pedal does not return to its original position.

  The object of the present invention is to provide a driver seat floor that exhibits a high anti-slip effect on the carpet on the floor and does not prevent the accelerator pedal from returning to its original position even if it is accidentally placed on the accelerator pedal. Is to provide a mat.

  A floor mat for an automobile driver seat according to the present invention includes a front surface side carpet and a back surface side carpet adhered to the back surface side of the front surface side carpet. The front side carpet has a front side base fabric and a front side pile yarn planted on the front side base fabric, and the back side carpet has a back side base fabric and a back side pile yarn planted on the back side base fabric. . The back side carpet is divided into a first region near the accelerator pedal of the automobile and a second region far from the accelerator pedal. The back side pile yarn in the second region has an engagement region for enhancing the anti-slip effect at the tip portion, but the back side pile yarn in the first region has an engagement region at the tip portion. Not done.

  According to the present invention having the above configuration, the floor mat as a whole exhibits a high adhesion effect and anti-slip effect on the floor interior carpet, but the first region near the accelerator pedal has a weak adhesion effect on the interior carpet, Even if the floor mat is accidentally placed on the accelerator pedal and used, it does not prevent the accelerator pedal from returning to its original position.

  In one embodiment, the first region is located on one side in the width direction of the floor mat (the side where the accelerator pedal is located), and the second region is located on the other side in the width direction.

  In a preferred embodiment, the engagement region of the back pile yarn in the second region is a crimped portion formed by heating the tip portion of the back pile yarn. In another embodiment, the engagement area of the backside pile yarn in the second area is hook-shaped. The engagement region of the back side pile yarn in the second region exerts a high adhesion effect and a high anti-slip effect on the carpet on the interior floor located below. The back side pile yarn in the first region exhibits an anti-slipping effect in the front-rear direction and the width direction with respect to the carpet, but has no engagement region at the front end portion, so that the adhesive effect on the carpet is weak.

  Preferably, the thickness of one filament constituting the back side pile yarn is larger than the thickness of one filament constituting the front side pile yarn, and the back side pile yarn is constituted more than the number of filaments constituting the front side pile yarn. Fewer filaments. The material of the back side pile yarn is, for example, nylon, polypropylene or polyester.

  According to a preferred embodiment of the present invention, the back side carpet including the back side pile yarn is provided on the back side, and the thickness of one filament constituting the back side pile yarn is larger than the thickness of one filament constituting the front side pile yarn. Since the back pile yarn in the second region has an engagement region at the tip portion thereof, an excellent anti-slip effect can be exhibited while maintaining good treading comfort. In addition, according to the present invention, the number of filaments constituting the back side pile yarn is less than the number of filaments constituting the front side pile yarn, so that the back side pile yarn is maintained in the automobile while maintaining good comfort. The anti-slip effect of the back side pile yarn can be enhanced by making it easier to entangle with the carpet on the interior floor.

In addition, as the adhesive layer 200, SBR latex, NBR latex, and hot melt adhesive are used. As the bonding method, in the case of SBR latex and NBR latex, hot air drying, hot melt adhesive is used. In some cases, a cooling process may be mentioned.

[Engagement region 301a of back side pile yarn 301]
As shown in FIG. 2, the back surface side carpet 300 is divided into a first area A close to the accelerator pedal 1 of the automobile and a second area B far from the accelerator pedal 1. The back side pile yarn 301 in the second region B has an engagement region 301a for enhancing the anti-slip effect at the tip portion, but the back side pile yarn 301 in the first region A is at the tip portion. Does not have an engagement area.

  For example, the engagement region 301 a is a crimped portion formed by heating the tip portion of the back side pile yarn 301. As another example, the back side pile yarn 301 may be bent at the leading end.

[Method of forming engagement region 301a]
As a method for forming the crimped portion by heating and melting the tip portion of the back side pile yarn 301, for example, there are the following methods.

  a) Direct flame method in which the pile yarn surface is melted directly with a gas burner.

  b) A technique in which the pile yarn surface is melted in a non-contact manner by an infrared heater or hot air using electricity or gas.

  Further, as a method for melting only the tip portion of the backside pile yarn 301 in the second region B and preventing the tip portion of the backside pile yarn 301 in the first region A from being melted, for example, the following method is used. is there.

  a) A region where no heat is applied or a region where heat is not radiated is provided on the heating device side.

  b) Cover the first area A with a heat-resistant plate or the like so that the first area A of the carpet 300 on the back surface side of the floor mat 10 is not exposed to heat.

  With the above-described method of forming the engagement region 301a, the region where the tip portion of the back pile yarn 301 is melted and the region where the tip is not melted are not visually recognized and do not affect the appearance. In addition, even if touched with a hand, the difference between the two areas is not known, so the touch feeling is not affected.

  When the entire nonwoven fabric is baked with a gas burner or the like to give an anti-slip effect, it feels firm when you touch the molten part with your hand. However, when only the tip of the single yarn of the back side pile yarn 301 is melted as in the embodiment of the present invention, it is not known even if it is touched by hand without damaging the texture of the yarn. Furthermore, since there is little damage of the pile fiber after heat-melting, it does not affect the sound absorption effect.

[Effects of Embodiments of FIGS. 1 and 2]
Since the back side pile yarn 301 bites into the interior floor carpet, it exhibits a good anti-slip effect in the vehicle front-rear direction and the width direction. The back pile yarn 301 in the second region B has an engagement region 301a for enhancing the anti-slip effect at the tip portion. Since the engagement region 301a is firmly entangled with the interior floor carpet, the effect of adhesion of the floor mat 10 to the interior floor carpet (adhesion effect in the mat thickness direction) is enhanced. In this way, the floor mat as a whole exhibits a high adhesion effect and anti-slip effect on the interior floor carpet.

  On the other hand, since the back pile yarn 301 in the first area A close to the accelerator pedal 1 does not have an engagement area, the bonding effect on the interior floor carpet is weak. Therefore, even if the user accidentally places the floor mat on the accelerator pedal and steps on the accelerator pedal in that state, the back side pile yarn 301 in the first region A covering the accelerator pedal is firmly attached to the floor carpet in the vehicle. Since it does not adhere, the floor mat 10 around the accelerator pedal does not adhere to the vehicle interior floor, and does not prevent the accelerator pedal from returning to its original position.

  In the floor mat 10, the back surface side carpet 300 including the back surface sound absorbing cloth 302 is provided on the back surface side. Also, compared to the front pile yarn 101, a thick filament is used for the back pile yarn 301, the number of filaments is reduced, the total Dtex is reduced, and the number of gauges and stitches are reduced. By doing so (pile yarn density is sparser on the back side than on the front side), the back side carpet 300 maintains a comfortable feeling on the back side carpet 100 while the pile yarn 301 is on the back side carpet 300. Becomes entangled with the carpet inside the car, and a high anti-slip effect can be obtained. Further, since the back surface side carpet 300 is provided with the back surface sound absorbing cloth 302, it is possible to enhance the sound absorbing effect.

  Furthermore, by using the adhesive layer 200 having a waterproof effect, it is possible to prevent water leakage to the carpet inside the automobile. Further, by using the nonwoven fabric as the material constituting the floor mat 10, it is possible to reduce the weight and cost of the floor mat 10.

  In order to further enhance the anti-slip effect of the automobile floor mat 10, backside pile yarn having a structure shown in FIGS. 6 to 8 may be used. The back side pile yarn 301A shown in FIG. 6 is a bundle of the back side pile yarn 301 around a filament 32 of 6 + 66 nylon copolymer 32a and 66 nylon 32b. The back side pile yarn 301B shown in FIG. 7 is bundled using only the filament 32 of 6 + 66 nylon copolymer 32a and 66 nylon 32b. The back side pile yarn 301C shown in FIG. 8 is a bundle of filaments 32A made of nylon, polyester, or the like.

  The filament 32 obtained by twisting the 6 + 66 nylon copolymer 32a and the 66 nylon 32b is obtained by polymerizing the low melting point member around the high melting point member so that both members are fused by heat of a dryer or the like. By making the yarn even stronger, it can be easily entangled with the carpet on the floor of the vehicle, and it can be expected to increase the engagement force of the vehicle with the carpet in the vehicle.

[Division between first area A and second area B]
In the embodiment shown in FIG. 1, the first region A is located on one side of the floor mat 10 in the width direction, and the second region B is located on the other side in the width direction. In the embodiment shown in FIG. 3, the first region A close to the accelerator pedal is located on the front side in the front-rear direction of the floor mat, and the second region B far from the accelerator pedal is located on the rear side in the front-rear direction of the floor mat. doing. In the embodiment shown in FIG. 4, the first region A is L-shaped along the L-shaped opening close to the accelerator pedal.

[Other Embodiments]
FIG. 9 shows another embodiment of the floor mat.

  The basic structure of the floor mat 20 is the same as that of the floor mat 10 shown in FIG. 2, and the difference is that a surface sound-absorbing cloth 103 is added as the surface-side carpet 100. As the material of the surface sound-absorbing cloth 103, for example, the following is selected.

Type: Nonwoven fabric (needle punch)
Material: Polypropylene, Polyester Weight: 60 g / m ² or more and 500 g / m ² or less In the floor mat 20 having the above-described configuration, the same effect as in the first embodiment can be obtained, and the surface sound-absorbing cloth 103 is added. This makes it possible to further improve the soundproofing effect and to improve the stepping comfort.

  The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the illustrated embodiments, and various modifications and variations can be made within the same or equivalent scope of the present invention. Is possible.

  The present invention can be advantageously used as a floor mat exhibiting a high anti-slip effect and excellent in safety.
