[0003] PATENT DOCUMENT 1 Japanese Utility Model Registration No. 3075999 SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION

[0004] By the way, the back surface water-repellent mat (so-called PVC mat) provided on the back surface of the seat back of a vehicle seat is configured by laminating a water-repellent layer made of a polyvinyl chloride sheet and a surface layer made of felt. When such a back surface water-repellent mat is rolled up with the water-repellent layer on the inner side, wavy wrinkles (folding wrinkles) occur in the water-repellent layer.

[0005] An object of the present invention is to obtain a back surface water-repellent mat that hardly causes wrinkles in the water-repellent layer even when rolled up, and a vehicle seat provided with the back surface water-repellent mat. MEANS FOR SOLVING THE PROBLEM

[0006] The first embodiment of the back water-repellent mat is a back water-repellent mat provided on the back of the seat back of a vehicle seat, and comprises a water-repellent layer made of a polyvinyl chloride sheet and a surface layer made of felt, which is laminated on one side of the water-repellent layer and has a number of slits formed thereon.

[0007] In the first embodiment of the back water-repellent mat, a surface layer made of felt is laminated to one side of a water-repellent layer made of a polyvinyl chloride sheet. Numerous slits are formed in this surface layer. As a result, even when this back water-repellent mat is rolled up with the water-repellent layer facing inward, wrinkles are less likely to form in the water-repellent layer.

[0008] In the second embodiment, the water-repellent mat on the back has the slit in a straight line shape, as in the first embodiment.

[0009] In the second embodiment of the water-repellent mat on the back, the numerous slits formed on the surface are in a straight line shape, which makes it easier to prevent the release paper of the double-sided tape from tearing, for example, when the felt constituting the surface is felt with double-sided tape.

[0010] In the third embodiment, the water-repellent mat on the back has the slits in a cross shape, as in the first embodiment.

[0011] In the third embodiment of the water-repellent mat on the back, the numerous slits formed on the surface are arranged in a cross shape, which enhances the wrinkle-suppressing effect, as mentioned above.

[0012] The fourth embodiment of the vehicle seat comprises a seat cushion on which the occupant of the vehicle sits, and a seat back that supports the back of the occupant and has a water-repellent mat on the back of the back in any one of the first to third embodiments.

[0013] In the fourth embodiment of the vehicle seat, the back of the occupant seated on the seat cushion is supported by the seat back. The water-repellent mat provided on the back of this seat back is of any one of the first to third embodiments, and therefore the aforementioned effect is obtained. [Effects of the Invention]

[0014] As explained above, according to the present invention, wrinkles are less likely to occur in the water-repellent layer even when the water-repellent mat on the back is rolled up. [Brief explanation of the drawing]

[0015] [Figure 1] This is a perspective view showing a vehicle seat according to an embodiment. [Figure 2] This is a rear view showing the water-repellent mat on the back according to the embodiment. [Figure 3] This is a front view showing the water-repellent mat on the back according to the embodiment. [Figure 4] This is a front view showing a modified example of the embodiment, specifically a water-repellent mat on the back. [Modes for carrying out the invention]

[0016] The following describes a vehicle seat 10 according to one embodiment of the present invention with reference to Figures 1 to 3. Note that some reference numerals may be omitted in the figures for clarity. The arrows FR, LH, and UP, as indicated in the figures, indicate the front, left, and top of the vehicle seat 10, respectively. Hereafter, when simply using the directions front, back, left, right, up, and down, these directions refer to the direction relative to the vehicle seat 10.

[0017] As shown in Figure 1, the vehicle seat 10 according to this embodiment is a rear seat for three people and comprises a seat cushion 12 on which the occupants sit, a seat back 14 that supports the occupants' backs, and three headrests 16 that support the occupants' heads. The seat back 14 is divided into a right seat back 14R for one person and a left seat back 14L for two people. The right seat back 14R and the left seat back 14L are each connected to the floor of the vehicle body via hinge brackets (not shown) and can be folded forward onto the seat cushion 12.

[0018] The left and right seat backs 14L and 14R each include a frame (not shown) that is a skeletal member, pads 18L and 18R that are cushion members attached to the frame, and trim covers 20L and 20R that are outer skins covering the pads 18L and 18R. The frame is configured by joining, for example, a press-formed metal plate material or a metal pipe material. The pads 18L and 18R are made of a foam such as urethane foam.

[0019] The trim covers 20L and 20R each include cover main bodies 22L and 22R that constitute the front surface, top surface, left surface and right surface of the seat backs 14L and 14R, and back surface water-repellent mats 24L and 24R (see FIG. 2 and FIG. 3) that constitute the back surface of the seat backs 14L and 14R. The cover main bodies 22L and 22R are formed by sewing a plurality of skin pieces made of, for example, fabric material, leather or synthetic leather, and cover the front surface, top surface, left surface and right surface of the pads 18L and 18R.

[0020] The back surface water-repellent mats 24L and 24R are each a so-called PVC mat, and have a water-repellent layer 26 made of a polyvinyl chloride sheet and a surface layer 28 made of felt. These back surface water-repellent mats 24L and 24R are arranged in a posture where the water-repellent layer 26 faces rearward and the surface layer 28 faces forward. Holes H and notches N are formed in each of these back surface water-repellent mats 24L and 24R.

[0021] The felt constituting the surface layer 28 is, for example, a felt with double-sided tape, and is attached (laminated) to one surface of the water-repellent layer 26 by the double-sided tape. A large number of slits S are formed in the surface layer 28 at intervals in the vertical, horizontal, left and right directions. Each of the large number of slits S penetrates through the surface layer 28.

[0022] Each slit S is, by way of example, formed in a horizontal straight line shape, with the length in the left-right direction set to, for example, 20 millimeters, and the pitch in the left-right direction set to, for example, 10 millimeters. In each of the back surface water-repellent mats 24L and 24R, slits S are not formed in a region (refer to the two-dot chain line A in FIG. 3) within a certain range (for example, 10 millimeters) from the outer shape, the holes H and the notches N.

[0023] The shape of the slit S is not limited to a horizontal straight line shape, and may be a vertical straight line shape or an oblique straight line shape. Further, for example, as in the modified example shown in FIG. 4, the slits S may be formed in a cross shape. In addition, the shape of the slit S can be appropriately changed to a U-shape, a V-shape, a zigzag shape, an S-shape, or the like. Further, the configuration is not limited to the one in which the slits S are arranged at equal intervals, and the slits S may be arranged at unequal intervals.

[0024] In the back surface water-repellent mats 24L and 2R having the above configuration, a surface layer 28 made of felt is laminated on one surface of a water-repellent layer 26 made of a polyvinyl chloride sheet. A large number of slits S are formed in this surface layer 28. As a result, even if the back surface water-repellent mats 24L and 24R are tightly rolled with the water-repellent layer 26 on the inner side, wavy wrinkles are less likely to occur in the water-repellent layer 26. The back surface water-repellent mats 24L and 24R are rolled, for example, during sewing (production) of the trim covers 20L and 20R, or during covering of the pads 18L and 18R with the trim covers 20L and 20R.

[0025] Further, in the back surface water-repellent mats 24L and 24R, since the large number of slits S formed in the surface layer 28 are in a straight line shape, when the felt constituting the surface layer 28 is a felt with double-sided tape as in the present embodiment, it is easy to prevent the release paper of the double-sided tape from being torn.

[0026] Incidentally, as in the modified example shown in FIG. 4, when the large number of slits formed in the surface layer 28 are in a cross shape, the aforementioned effect of suppressing the occurrence of wrinkles can be enhanced.

[0027] Furthermore, although the above embodiment described the case in which the present invention is applied to a vehicle seat 10, the present invention is not limited to this and can also be applied to seats for vehicles other than vehicles (for example, aircraft and ships).

[0028] Furthermore, the present invention can be implemented with various modifications without departing from its spirit. Of course, the scope of the present invention is not limited to the embodiments described above. [Explanation of Symbols]
