However, in the seat cover mounting structure described in Patent Document 1, when the magnetic field of the permanent magnet is generated on the surface side of the seat body, it does not affect electronic devices such as a magnetic card or a pacemaker held by the passenger. may affect If the magnetic force is weakened to such an extent that no magnetic field is generated on the surface side of the seat body, the degree of adhesion between the seat cover and the seat body is weakened.

The present invention has been proposed in view of such circumstances. That is, it is an object of the present invention to provide a seat cover mounting structure that can minimize the formation of a magnetic field on the surface side of the seat.

In order to achieve the above object, a seat cover mounting structure according to the present invention includes a body-side member embedded in a seat body, and a connecting member provided on the seat cover for mounting the seat cover to the seat body. and a cover-side member to be attached, wherein the body-side member and the cover-side member are adhered by magnetic force, and the positive electrode and the negative electrode in the magnetic force are arranged in the width direction of the sheet body. and

The seat cover mounting structure according to the present invention has a plurality of magnetic bodies, and the magnetic bodies are arranged such that the magnetic poles of the magnetic bodies adjacent to each other in the width direction of the seat body are opposite to each other. Characterized by

In the seat cover mounting structure according to the present invention, the cover-side member includes a cover-side first member attached to the connection member, and a metal seat cover attached to the cover-side first member and adhered to the main body-side member. and a second cover-side member, wherein a side plate portion of the second cover-side member attached to a side surface of the first cover-side member straddles the positive electrode and the negative electrode. Characterized by

The seat cover mounting structure according to the present invention is characterized in that the body-side member has a connecting portion connected to the seat body.

A seat cover mounting structure according to the present invention includes a body-side member embedded in a seat body, and a cover-side member mounted to a connecting member provided on the seat cover for mounting the seat cover to the seat body, The body-side member and the cover-side member are adhered by magnetic force, and the positive and negative electrodes of the magnetic force are arranged in the width direction of the sheet body. That is, since the lines of magnetic force are generally directed from the positive electrode to the negative electrode, if the positive electrode and the negative electrode are arranged in the width direction of the sheet body, the direction of the magnetic force lines will also be in the width direction. In other words, the magnetic field is distributed in the width direction of the seat cover at the embedding site, not from the embedding site in the body-side member to the surface side of the seat cover. Therefore, the formation of the magnetic field on the surface side of the sheet body can be suppressed as much as possible, and the magnetic field can be formed in a range that does not protrude on the surface side of the sheet body. If the positive electrode and the negative electrode were aligned in the depth direction from the seat body, the lines of magnetic force generated from the positive electrode would be directed toward the seat cover. It may be distributed on the surface side.

The seat cover mounting structure according to the present invention has a plurality of magnetic bodies, and the magnetic bodies are arranged such that the magnetic poles of the magnetic bodies adjacent to each other in the width direction of the seat body are reversed to each other. That is, for example, one magnetic body has its positive pole facing upward and its negative pole facing downward, and the other magnetic body has its negative pole facing upward and its positive pole facing downward. will be adjacent. Since the magnetic lines of force are directed from the positive pole of one magnetic body to the negative pole of the other magnetic body, the formation of the magnetic field on the surface side of the sheet body can be suppressed as much as possible, and the magnetic field can be directed to the surface side of the sheet body. It can also be formed within a range that does not overhang.

A seat cover mounting structure according to the present invention includes a first cover-side member attached to a connection member, and a metal cover-side member attached to the first cover-side member and adhered to a body-side member. Among the cover-side second member, the side plate portion attached to the side surface of the cover-side first member straddles the positive electrode and the negative electrode. That is, since the magnetic lines of force directed from the positive electrode to the negative electrode have a magnetic path in the side plate portion made of metal straddling the magnetic poles, in principle, the magnetic field is generated in the side plate portion. Therefore, the magnetic field can be formed within a range that does not protrude to the surface side of the sheet body. It should be noted that if the side plate portions were arranged only on the positive electrode and only on the negative electrode, the lines of magnetic force would diverge from the upper end through the side plate portions, the magnetic field would attenuate, and the magnetic field could be distributed on the surface side of the seat cover. have a nature.

In the seat cover mounting structure according to the present invention, the body-side member has a connecting portion that is connected to the seat body. Therefore, for example, compared to a method in which a body-side member having a plurality of holes and unevenness formed therein is embedded in foamed polyurethane raw material or the like, and the polyurethane raw material hardens to fit around the holes and unevenness in a complicated manner. By doing so, the main body side member can be easily fixed to the seat main body.

Each part described above is assembled as follows.

In FIG. 5 , when the metal clip 50 is attached to the resin clip 41 , the metal clip 50 and the resin clip 41 are brought relatively close to each other in the vertical direction, and the side plate portions 52 of the metal clip 50 are aligned with the side portions 43 of the resin clip 41 . It slides facing the pressing projection 49 . At this time, the upper end of the side plate portion 52 moves along the protrusion inclined surface 48 of the engaging protrusion 47, so that the side plate portion 52 is elastically deformed as the metal clip 50 and the resin clip 41 approach each other in the vertical direction. spread out gradually. When the engaging protrusion 47 of the side plate portion 43 is inserted into the convex hole 54 of the side plate portion 52 , the side plate portion 52 returns to its original state due to the restoring force, and the resin clip 41 is sandwiched between the side plate portions 52 . Thus, the metal clip 50 and the resin clip 41 are engaged (see FIG. 3).

In this state, as shown in FIGS. 3 and 4, the resin clip 41 and the metal clip 50 are engaged with each other through gaps X ₁ to X ₃ . Specifically, when the engaging projection 47 of the resin clip 41 is inserted into the convex hole 54 of the metal clip 50, the gap _X1 is formed between the engaging projection 47 and the engaging hole 53 of the metal clip 50. is vacant. A gap _X2 is provided between the upper end of the metal clip 50 and the flange portion 46 of the resin clip 41 . A gap _X3 is provided between the lower plate portion 51 of the metal clip 50 and the lower surface portion 42 of the resin clip 41 .

When the end member 10 is attached to the resin clip 41, the end member 10 and the resin clip 41 are brought relatively close to each other in the vertical direction, and the side surface portion 43 of the resin clip 41 faces the outer peripheral surface of the end member 10 and slides. do. At this time, the end member locking portion 44 of the side portion 43 moves along the outer peripheral surface of the end member 10, so that the end member locking portion 44 moves closer to the end member 10 and the resin clip 41 in the vertical direction. Elastically deforms and expands gradually. When the end member 10 reaches the lower surface portion 42 of the resin clip 41 , the end member locking portion 44 returns to its original state due to the restoring force, and the end member 10 is sandwiched by the end member locking portion 44 . It locks on the upper end. Thus, the end member 10 and the resin clip 41 are engaged.

The order in which the resin clip 41, the metal clip 50 and the end members 10 are attached is arbitrary. Therefore, as described above, the end member 10 and the resin clip 41 may be engaged after the resin clip 41 and the metal clip 50 are engaged, or the end member 10 and the resin clip 41 may be engaged. After that, the resin clip 41 and the metal clip 50 may be engaged.

The permanent magnet 11 is attached to the magnet attachment portion 23 of the body-side member 20 by sliding along the entire length of the bracket 21 . Specifically, when the permanent magnet 11 is inserted into the magnet mounting portion 23 until the rear end hits the retaining piece 26 , the front end is locked by the second locking piece 25 . At the same time, the permanent magnet 11 is locked by the first locking piece 24 .

In this state, the body-side member 20 is embedded in the seat body 3 and engaged with the seat wire, as shown in FIG. The sheet wires are installed in advance in the mold for the sheet body 3 . For example, a polyurethane raw material or the like is poured into the mold, and the polyurethane raw material foams and hardens through a predetermined process. The connection body portion 30 of the body-side member 20 is inserted into the hardened polyurethane raw material, and the sheet wire is engaged with the distal end portion 35 and arranged in the wire connection space 36 . In this manner, the body-side member 20 is embedded and attached to the seat body 3 .

In the mounting structure 1 configured as described above, as shown in FIG. 2, when the seat cover 4 is mounted on the seat body 3, the cover-side member 40 is attached to the body-side member 20 by magnetic force. be done. Specifically, the lower plate portion 51 of the metal clip 50 of the cover-side member 40 is adhered to the upper surface of the permanent magnet 11 of the body-side member 20 . In this state, the permanent magnets 12 and 13 are arranged side by side in the width direction of the sheet body 3 . That is, they are arranged in the direction in which the seat cover 4 extends, and the depths from the permanent magnets 12 and 13 to the seat cover 4 are substantially the same. Note that the width direction of the seat body 3 refers to the direction in which the seat body 3 extends. For example, in FIG. Further, for example, in the seat back 6, it is the direction in which the backrest surface spreads, such as the left-right direction and the up-down direction.

Next, the effects of the mounting structure 1 will be described together with the state of the magnetic field based on the drawings. FIG. 6 shows the state of the mounting structure 1 and the magnetic field viewed from the side. FIG. 7 shows the operation of the mounting structure 1 viewed from the side.

As shown in FIG. 6, the permanent magnet 11 has the positive electrode N of the first permanent magnet 12 and the negative electrode S of the second permanent magnet 13 arranged side by side on the top surface, while on the bottom surface: The negative electrode S of the first permanent magnet 12 and the positive electrode N of the second permanent magnet 13 are arranged side by side. With this configuration, since the magnetic lines of force M are directed from the positive electrode N to the negative electrode S, the direction of the magnetic lines of force M is the direction in which the permanent magnets 12 and 13 are arranged, which is the width direction of the seat body 3 . That is, the magnetic field is not distributed above the seat cover 4 (the vertical direction in FIG. 6) from the portion embedded in the seat body 3, but in the direction in which the seat body 3 extends in the embedded portion (the horizontal direction in FIG. 6). ). Therefore, the formation of the magnetic field on the surface side of the seat cover 4 can be suppressed as much as possible, and the magnetic field can be formed in a range that does not protrude above the seat cover 4 . Therefore, even if the passenger has an electronic device such as a magnetic card or a pacemaker, it is possible to prevent the magnetic field from interfering with them.

In addition, since the positive electrode N and the negative electrode S are arranged on the upper surface, the magnetic flux density on the upper surface is high, so that the thickness of the permanent magnet 11 can be reduced while the metal clip 50 is securely adhered by magnetic force. Furthermore, if the permanent magnet 11 is thin, the range in which the magnetic field is generated is also suppressed in the thickness direction of the permanent magnet 11 , so the magnetic field can be formed within a range that does not protrude above the seat cover 4 .

As shown in FIG. 7 , according to the mounting structure 1 , the angle of the resin clip 41 of the cover-side member 40 changes or moves with respect to the body-side member 20 . That is, when the seat 2 is pressed toward the seat main body 3, for example, when a passenger is seated on the seat 2 or baggage is placed on the seat 2, the seat cover 4 is pulled and suspended at the pressed portion. The cotton cloth 9 is pulled. Therefore, the cover-side member 40 is loaded in the direction D away from the body-side member 20 . Here, between the resin clip 41 and the metal clip 50, a gap _X1 is provided between the engaging protrusion 47 and the engaging hole 53, and the upper end of the metal clip 50 and the flange portion 46 of the resin clip 41 are separated. A gap _X2 is provided therebetween, and a gap _X3 is provided between the lower plate portion 51 of the metal clip 50 and the lower surface portion 42 of the resin clip 41 (see FIGS. 3 and 4). That is, since there is a so-called play of X ₁ to X ₃ between the resin clip 41 and the metal clip 50, even when a load is applied, the resin clip 41 does not become the engaging protrusion within the allowable play range. 47 is tilted with respect to the metal clip 50 . At that time, the metal clip 50 remains adhered to the permanent magnet 11 . Therefore, it is possible to prevent the seat cover 4 from unintentionally coming off the seat body 3 .

Also, as shown in FIG. 7 , when the resin clip 41 is tilted with respect to the metal clip 50 , the flange portion 46 of the resin clip 41 comes into contact with the edge of the metal clip 50 . That is, the resin clip 41 tilted with respect to the metal clip 50 is restricted from tilting beyond a certain level by the flange portion 46 coming into contact with the edge of the metal clip 50 . Therefore, it is possible to prevent the resin clip 41 from coming off the metal clip 50 .

Moreover, since the edge of the metal clip 50 is covered with the flange portion 46 of the resin clip 41, the hanging cotton cloth 9 and the seat cover 4 can be prevented from rubbing against the metal clip 50 and being damaged.

Next, a mounting structure according to a second embodiment and a mounting structure according to a third embodiment of the present invention will be described based on the drawings. FIG. 8 shows the state of the magnetic field of the mounting structure 201 according to the second embodiment viewed from the side.

As shown in FIG. 8, in the second embodiment, the number of permanent magnets 11 is different from that in the mounting structure 1. As shown in FIG. The single permanent magnet 11 has the positive electrode N and the negative electrode S arranged side by side on the upper surface, and the side plate portion 52 of the metal clip 50 straddles the positive electrode N and the negative electrode S. That is, the longitudinal direction of the side plate portion 52 (horizontal direction in FIG. 8) is aligned with the direction in which the positive electrode N and the negative electrode S of the permanent magnet 11 are aligned (horizontal direction in FIG. 8). With this configuration, magnetic lines of force M directed from the positive pole N to the negative pole S on the upper surface side of the permanent magnet 11 use the side plate portion 52 spanning the magnetic poles as a magnetic path, and a magnetic field is generated within the side plate portion 52 . Therefore, the magnetic lines of force M can be prevented from diverging upward, and the magnetic field can be formed within a range that does not protrude upward from the seat cover 4 .

As shown in FIG. 9 , in the third embodiment, the bracket 321 has a different shape than the main body member 20 of the mounting structure 1 . Bracket 321 has fixing holes 355 and fixing protrusions 356 formed at the four corners of a substantially rectangular base portion 322 . The fixed protrusion 356 is substantially perpendicular to the base portion 322 and rises upward from the base portion 322 . The fixing hole portion 355 vertically penetrates the base portion 322 in the vicinity of the inner side of the fixing protrusion 356 . A seat body connection portion is not formed in the lower portion of the base portion 322 .

When the permanent magnet 11 is attached to the bracket 321 and the upper surface of the permanent magnet 11 is adhered to the installation portion of the mold, the raw material for polyurethane or the like is poured into the mold. The irregularities of the main body side member 320 are evenly filled except for the . The polyurethane raw material particularly fills the fixing holes 355 of the bracket 321 and adheres to the fixing projections 356 . Through a predetermined process, the polyurethane raw material foams and hardens, and particularly around the fixing hole 355 and the fixing projection 356, the body-side member 320 firmly adheres to the hardened polyurethane raw material. Thus, the seat body 3 in which the body-side member 320 is embedded is formed. That is, around the fixing hole 355 and the fixing projection 356, the cured polyurethane raw material is intricately fitted with the body-side member 320 with a wide contact area. Stick. Therefore, the body-side member 320 can be firmly fixed to the seat body 3 . In particular, when the seat cover 4 is pulled and the body side member 320 is pulled upward, the resistance generated on the contact surface between the body side member 320 and the seat body 3 can be improved.

Also in the first embodiment, the side plate portion 52 of the metal clip 50 straddles the positive electrode N of the first permanent magnet 12 and the negative electrode S of the second permanent magnet 13 as in the second embodiment. In another embodiment of the present invention, the side plate portion 52 straddles only the positive pole N of the first permanent magnet 12 or the negative pole S of the second permanent magnet 13 . Moreover, in other embodiments, it has three or more magnetic bodies. In another embodiment, the cover-side first member and the cover-side second member are integrally made of metal. Moreover, in another embodiment, the body-side member and the magnetic body are integrated.
