Abstract

PURPOSE:To reduce the shift of a mat by forming shift preventing projections on the back of said mat and increasing the density of said projections in line with applied weight. CONSTITUTION:A synthetic resin backing layer 15 is formed on the back of the base fabric 14 of an automobile mat 11. And, shift preventing projections 12 are formed on the back of the backing layer 15. The projections 12 are formed in such a way that the density of the projections at places which is subjected to a weight of high frequency and strength is higher than the density at places subjected to a weight of low frequency and strength. That is, the density of the projections 12 in a part with which a foot is brought into contact at the time of operating an accelerator pedal and a clutch pedal is made higher than the density of other parts. Accordingly, since the projections are provided in line with weight applied to each part, the shift of the mat 11 can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automobile mat, and more particularly to an automobile mat having a structure for preventing displacement of the mat.

(Prior Art) Conventionally, as shown in FIGS. 7 and 8, in car mats that are used by laying them on the floor of a car, a vertical auxiliary complex is placed on the back surface of the mat (1). A protrusion protruding in the direction (2
) are provided at predetermined intervals to prevent the mat (1) from shifting by using the frictional resistance generated between the protrusions (2) and the carpet (3) laid on the floor (Jitsukai Sho. 49
-2:1935).

(Problem to be solved by the invention) However, in this mat (1), there are protrusions (
2) interval was determined. For this reason, when the accelerator or clutch is operated under heavy load, such as when getting on or off, the provided protrusion (2) alone will not get caught on the carpet (3), and the carpet (3) and mat ( 1)
Since the frictional resistance between the mat (1) and the mat (1) was small, the mat (1) could not be sufficiently resisted, causing the problem that the mat (1) would shift.

The present invention has been made in view of these problems, and it is an object of the present invention to provide an automobile mat having a structure that does not shift even when a load is applied during accelerator operation, clutch operation, or when getting on and off the vehicle. That is.

(Means for Solving the Problems) That is, the present invention provides an automobile mat having a resin backing layer on the back surface of which is formed with protrusions for preventing slippage, in which the protrusions at the portion where the load is applied correspond to the load applied to the mat. This is an automotive mat that is characterized by a high density.

(Function) Therefore, in the automatic heavy duty mat of the present invention, the density of the protrusions in the part where the load is applied is increased, so that in the part where the load is applied, there are protrusions that contact the carpet on the floor of the car to counteract the load. The number of mats is large, and therefore mat misalignment can be significantly reduced.

(Example) The automobile mat of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows the back side of the car mat of the present invention, and FIG. 2 shows an enlarged sectional view of the main parts of the car mat.

This automobile mat (1) has a backing layer (15) made of synthetic resin formed on the back side of a base fabric (14) into which piles (13) are formed.

As shown in Fig. 4, the base fabric (14) is a relatively strong core material, into which piles (1 piece) of synthetic fibers etc. are driven into a predetermined shape without any gaps. It has a long jutan shape. A backing layer (15) is formed on the back surface of this base fabric (14), and the bonding force between the pile (13) and the base fabric (14) is further increased.

The backing layer (15) is preferably made of a thermoplastic resin such as polyethylene, polyvinyl chloride, or polyester.
) is formed into a plate shape having a thickness of about 71 cm, and a backing layer (15) is formed.

Note that the type of resin and the thickness of the backing layer are not limited to these, and are determined by taking into consideration the material and structure of the carpet or base fabric attached to the floor of the vehicle interior.

On the back side of this backing layer (15) are protrusions (
12) is formed at the same time as the backing layer (15). This automobile mat (11) is formed with a high density of protrusions (12) in areas where the load is applied, in response to the load applied to the mat (11).

The load applied when operating the accelerator, clutch, or getting on or off the vehicle varies depending on the driver and passenger, but the frequency of application of the weight and the areas where the intensity of the applied weight is high are almost constant. Furthermore, the direction of the applied load is also approximately constant.

Therefore, in the automobile mat (11) of the present invention, the density of the protrusions (12) in the portions to which the load is applied, in other words, the frequency in which the weight is applied or the portions where the strength of the applied load is high, is It is formed higher than a part that is used relatively less frequently, for example, a part closer to the seat where the feet are rarely placed near. For example, as shown in Figure 1, the mat (11) for the driver's seat has the parts that the foot touches when operating the accelerator pedal or clutch pedal, and the side parts that are stepped on when getting on and off the vehicle. , protrusion (12) to prevent slippage,
The density of the protrusions (12) in other parts is 3 cmX 3 c+
It is formed with an interval of 1.5 cm
They are formed with high density at intervals of 1.5 cm, and have a large amount of catching on the carpet, so that they can sufficiently resist the load applied when operating the accelerator pedal or clutch pedal, or when getting on and off.

On the other hand, as shown in Figures 5 and 6, the mat (11) placed on the passenger seat or rear seat has a protrusion ( 12) or
While the protrusions (12) in other parts are formed at an interval of 3c x 3c, the density of the protrusions (12) is 1.5cm x 1, sc.
They are formed with high density at intervals of , and are able to sufficiently resist loads.

Is it possible to increase the density of the protrusions (12) on the entire back side of the mat (11)? In this case, the mat will be floating above the floor surface, and conversely, the mat will be less likely to get caught on the carpet. , it becomes easy to shift, which is not preferable.

Note that the ratio of the density of the protrusions (12) in the part to which the load is applied and the density of the protrusions (12) in the part to which the load is applied with relatively few incarnations is not limited to 2:1 as described above. , the ratio is determined by considering the strength and frequency of weighting.

Note that the density of the protrusions (12) may be set at multiple levels in consideration of the frequency of applying weight and the applied weight.

For example, in the case of a mat for the driver's seat, if the protrusions in the areas where little weight is applied are formed at intervals of 3 cs x 3 cm, and if this is taken as 1, then the protrusions in the areas where less weight is applied are the areas that are stepped on during pedal operation. The density of the protrusions on the right side portion and the left side portion is set at a ratio of 4:3:2. This allows the protrusions to respond accurately to the load applied to the mat, thereby further reducing misalignment of the mat.

In this way, the mat (11) can be prevented from shifting by forming the protrusions (12) at a high density in the areas where the load is applied in response to the load applied to the mat (11). .

Note that the automobile mat (11) of the present invention is not limited to the tufted mat described in -F, but also includes mats formed by bonding thick fibers using a needle punching method, etc., mats formed by flocking, etc. It may be.

(Effects of the Invention) As described in detail below, the present invention provides a mat for automobiles that has a resin backing layer on the back surface of which is formed with protrusions for preventing slippage, in which the weight is applied to the mat in response to the weight applied to the mat. This is an automobile mat that features a high density of protrusions.

Therefore, in the automobile mat of the present invention, since the density of the protrusions is increased in the portion where the load is applied, the load that counters the applied load is increased, and the misalignment of the mat can be significantly reduced. In particular, since it is possible to prevent the mat from shifting from a predetermined position, the mat does not interfere with pedal operation, allowing safe driving.
