Description

[Technical Field]

[0001] The present invention relates to a seat pad and a method for removing wrinkles from a seat cover. [Background technology]

[0002] BACKGROUND ART A seat pad having a seating surface on which an occupant sits and in which a ventilation channel is formed has been conventionally known (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-51688 Summary of the Invention [Problem to be solved by the invention]

[0004] A seat pad is covered with a cover, and a conventional method for removing wrinkles from the cover is to spray steam onto the cover. In the case of a breathable cover, after covering the seat frame with the seat pad and cover, a worker sprays steam onto the surface of the cover.

[0005] However, in the case of non-breathable upholstery, before placing the seat pad and upholstery on the seat frame, the worker inserts a steam wand between the upholstery and the seat pad to spray steam. As a result, tension is not applied to the upholstery, and the steam is not effective in removing wrinkles. In addition, wrinkles are difficult to remove in areas that the steam wand cannot reach. Furthermore, if a heater or other device is installed on the surface of the seat pad, there is a risk that the steam wand will damage the heater or other device.

[0006] Therefore, an object of the present invention is to provide a seat pad and a method for removing wrinkles from a surface, which can improve the effect of removing wrinkles from the surface, regardless of whether the surface is breathable or not. [Means for solving the problem]

[0007] In order to achieve the above object, a seat pad of a first aspect according to the present invention comprises a seat pad main body, a first groove portion formed in the seat pad main body so as to extend in one direction, a second groove portion formed in the seat pad main body so as to extend in a direction different from the one direction and continuous with the first groove portion, and an insertion hole formed at the intersection of the first groove portion and the second groove portion, into which the tip end of a steam wand from which steam is emitted can be inserted.

[0008] According to the first aspect of the invention, the seat pad body is formed with a first groove extending in one direction and a second groove extending in a direction different from the first direction and continuing to the first groove. An insertion hole is formed at the intersection of the first groove and the second groove, into which the tip of the steam wand from which steam is ejected can be inserted.

[0009] Here, the intersection of the first groove and the second groove is a location where wrinkles are likely to occur in the upholstery when the upholstery is placed over the seat pad. Therefore, by inserting the tip of a steam wand into an insertion hole formed at the intersection and spraying steam onto it, wrinkles in the upholstery are effectively removed. Thus, according to the present invention, the wrinkle removal effect on the upholstery is improved regardless of whether the seat pad is breathable or not.

[0010] In addition, a second aspect of the seat pad according to the present invention is a seat pad according to the first aspect, wherein the insertion hole is formed at a predetermined length from the intersection along the first groove portion and the second groove portion.

[0011] According to the second aspect of the invention, the insertion hole is formed at a predetermined length from the intersection along the first and second grooves. Therefore, steam sprayed from the tip of the steam wand flows easily along the first and second grooves, so wrinkles in the skin are more effectively removed.

[0012] Furthermore, a third aspect of the method for removing wrinkles from an upholstery according to the present invention includes a pad covering step of covering a seat frame with the seat pad of the first or second aspect, a skin covering step of covering at least the front surface side of the seat pad with skin, and a spraying step of inserting the tip of a steam wand from which steam is emitted into the insertion hole from the back side of the seat pad and spraying steam onto the upholstery.

[0013] According to the third aspect of the invention, the pad covering step covers the seat frame with the seat pad, the skin covering step covers the seat pad so as to cover at least the front side of the seat pad with the skin, and the spraying step inserts the steam-emitting tip of the steam wand into the insertion hole from the back side of the seat pad to spray steam onto the skin. Therefore, steam can be sprayed directly onto areas of the skin where wrinkles are likely to occur, effectively removing wrinkles from the skin. Thus, according to the present invention, the wrinkle removal effect on the skin is improved regardless of whether the seat pad is breathable or not. [Effects of the Invention]

[0014] As described above, according to the present invention, it is possible to improve the wrinkle-removing effect on the epidermis, regardless of whether the fabric has breathability or not. [Brief explanation of the drawings]

[0015] [Figure 1] 1 is a schematic front view showing an example of a seat pad according to an embodiment of the present invention; [Figure 2] 4 is a schematic front view showing an enlarged view of an insertion hole of the seat pad according to the embodiment. FIG. [Figure 3] FIG. 10 is a schematic side view showing the state in which the tip of the steam wand is inserted into the insertion hole of the seat pad according to the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. For ease of explanation, an example of a seat pad 20 according to this embodiment will be described, which is used in a seat back 12 of a vehicle seat 10. Therefore, in each drawing, the arrow UP indicates the upward direction of the vehicle seat 10, the arrow FR indicates the forward direction of the vehicle seat 10, and the arrow RH indicates the rightward direction of the vehicle seat 10. Furthermore, in the following description, when the up / down, front / rear, and left / right directions are mentioned unless otherwise specified, they refer to the up / down, front / rear, and left / right directions of the vehicle seat 10. Furthermore, the left / right direction is synonymous with the seat width direction.

[0017] 1, the seat back 12 of the vehicle seat 10 has a seat pad 20 that is placed over a seat back frame 16 (see FIG. 3) that constitutes the seat frame. The seat pad 20 is formed to a size that can support the back of an occupant (not shown), and has a seat pad main body 22 made of urethane foam or the like, and a plurality of grooves 24, 26, 28 formed on the surface side of the seat pad main body 22.

[0018] Specifically, a pair of first grooves 24 of a predetermined depth are formed at a predetermined interval in the left-right direction and extend in the up-down direction (one direction) from approximately the center of the seat pad main body 22 downward. Each first groove 24 separates the center side and the side side of the seat pad 20. In other words, the portions of the seat pad 20 that are further outward in the seat width direction than each first groove 24 form the side portions of the seat back 12 that protrude slightly forward.

[0019] The upper ends of the first grooves 24 in the seat pad main body 22 are connected to one another by second grooves 26 formed to extend at a predetermined depth in the seat width direction (a direction different from the one direction). In addition, a pair of third grooves 28 of a predetermined depth extend upward and outward in the vehicle width direction from locations in the seat pad main body 22 corresponding to the intersections of the first grooves 24 and the second grooves 26. The upper ends of the third grooves 28 reach the outer edge 22A of the seat pad main body 22, and each third groove 28 defines the upper end of a side portion of the seat back 12.

[0020] A pair of left and right holes 22B for inserting headrest stays (not shown) of a headrest are formed in the upper end surface 22U of the seat pad main body 22. As shown in Fig. 2, an insertion hole 30 penetrating the seat pad main body 22 is formed at the intersection of the first groove 24, the second groove 26, and the third groove 28 (at least the intersection of the first groove 24 and the second groove 26).

[0021] The insertion hole 30 is formed at a predetermined length from the intersection along the first groove portion 24 and the second groove portion 26. That is, the insertion hole 30 is formed in a substantially arc shape when viewed from the front as shown in Fig. 2. Then, as shown in Fig. 3, the tip portion 14D of the steam rod 14 is inserted into the insertion hole 30.

[0022] The steam rod 14 includes a grip portion 14A that is gripped by an operator, and a thin, elongated, generally hollow, cylindrical body portion 14C (having a smaller diameter than the grip portion 14A) that extends integrally from one longitudinal end of the grip portion 14A. The other longitudinal end of the grip portion 14A is connected in communication with a tube 15 whose other end is connected to a steam generator (not shown).

[0023] Furthermore, a switch 14B for turning the steam jet on and off is provided on one longitudinal end side of the grip part 14A. Furthermore, a plurality of holes (not shown) (at least four holes equally spaced circumferentially) are formed in the tip part 14D of the main body part 14C, which can jet steam in at least four directions. This allows the steam wand 14 to jet steam in at least four directions from the tip part 14D.

[0024] Next, the operation (method of removing wrinkles from the surface) of the seat pad 20 according to this embodiment configured as described above will be described.

[0025] First, the seat pad 20 is placed over the seat back frame 16 (part of which is shown in phantom lines in Figure 3) (pad covering step). Next, the cover 18 (part of which is shown in phantom lines intentionally separated in Figure 3) is placed over the seat pad 20 so as to cover at least the front surface side (cover covering step). After that, the tip 14D of the steam wand 14 is inserted into the insertion hole 30 from the back side of the seat pad 20, and steam is blown toward the cover 18 that is covered by the seat pad 20 (blowing step).

[0026] Here, a first groove portion 24 and a second groove portion 26 continuing from the first groove portion 24 are formed in the seat pad main body 22 of the seat pad 20, and the insertion hole 30 is formed at least at the intersection of the first groove portion 24 and the second groove portion 26. When the seat pad 20 is covered with the upholstery 18, the intersection of the first groove portion 24 and the second groove portion 26 is a location where wrinkles are likely to occur in the upholstery 18.

[0027] Therefore, in the method for removing wrinkles from an epidermis according to this embodiment, the tip 14D of the steam wand 14 is inserted into the insertion hole 30 formed at the intersection, and steam is blown onto the epidermis 18 from at least four sides. This allows steam to be blown directly onto areas of the epidermis 18 where wrinkles are likely to occur, effectively removing wrinkles from the epidermis 18. Thus, according to this embodiment, the effect of removing wrinkles from the epidermis 18 can be improved regardless of whether the epidermis is breathable or not.

[0028] Moreover, this insertion hole 30 is formed at least from the intersection of the first groove portion 24 and the second groove portion 26, over a predetermined length along the first groove portion 24 and the second groove portion 26. Therefore, as shown in Fig. 2, the steam blown from the tip portion 14D of the steam rod 14 flows easily along at least the first groove portion 24 and the second groove portion 26 (spreads over a wide range), and therefore wrinkles in the epidermis 18 can be removed more effectively.

[0029] Furthermore, in the method for removing wrinkles from an upholstery according to this embodiment, steam can be sprayed onto the upholstery 18 while the seat pad 20 and upholstery 18 are placed on the seat back frame 16. This allows wrinkles to be removed more effectively and prevents the wrinkles from returning. Furthermore, since the insertion hole 30 is the only location where the tip 14D of the steam wand 14 is inserted, the wrinkle removal work is easy, and even if a heater (not shown) is provided in the seat pad 20, there is no risk of damaging the heater.

[0030] Furthermore, because the insertion holes 30 are formed along the first groove portions 24 and the second groove portions 26, it is difficult to see (is inconspicuous) that a through hole has been formed in the seat pad 20 (seat pad main body 22) from the surface side of the skin 18. Therefore, it is possible to suppress or prevent a decrease in the cushioning performance of the seat pad 20 (seat pad main body 22), and also to suppress or prevent a decrease in the marketability of the vehicle seat 10.

[0031] The seat pad 20 and the method for removing wrinkles from the upholstery according to this embodiment have been described above with reference to the drawings. However, the seat pad 20 and the method for removing wrinkles from the upholstery according to this embodiment are not limited to those shown in the drawings, and appropriate design modifications are possible within the scope of the present invention. For example, if there are other intersections of multiple grooves in the seat pad main body 22, additional insertion holes 30 may be formed at those intersections. In other words, the number of insertion holes 30 is not limited to two as shown in the drawings.

[0032] Furthermore, the seat pad 20 according to this embodiment is not limited to being used to form the seat back 12 of the vehicle seat 10. The seat pad 20 according to this embodiment may be any seat pad in which at least a first groove portion 24 extending in one direction and a second groove portion 26 extending in a direction different from the one direction and continuing to the first groove portion 24 are formed in the seat pad main body 22, and an insertion hole 30 into which the tip portion 14D of the steam rod 14 can be inserted can be formed in the seat pad main body 22 at the intersection of the first groove portion 24 and the second groove portion 26.
