Outside, the size for projecting height in weir portion 5 with from inner wall 5b to outer wall 5c be dimensioned so as to roughly the same length.In addition, phase
Between inner wall 5c the length for being dimensioned so as to the substantially three times from inner wall 5b to the size of outer wall 5c.
When the specified position of aftermentioned upper mold 11 (with reference to Fig. 3) is equipped with reinforcement cloth 1, magnetosphere coated face 3 is disposed in
Position corresponding with magnet 14 (the reference Fig. 3) of upper mold 11 is disposed in.Therefore, by being magnetic in the formation of magnetosphere coated face 3
Layer 2, thus when reinforcement cloth 1 is installed on upper mold 11, magnetosphere 2 is adsorbable in magnet 14.
Magnetosphere coated face 3 is formed as flushing with the surface 1a of the reinforcement cloth 1 in the outside of the outer wall 5c in weir portion 5.That is, reinforcing
Cloth 1 is in the formation part for forming magnetosphere 2 and separates weir portion 5 relative to the forming portion and positions and do not form magnetosphere 2
In non-formation part (from the outside of outer wall 5c to the part of prescribed limit), be formed as the side i.e. back side (Fig. 1 opposite with surface 1a
(b) on the downside of face) flush.
Magnetosphere 2 is formed in the magnetosphere coated face 3 for reinforcing cloth 1.At this point, magnetosphere 2 is in the thickness direction for reinforcing cloth 1
(upper and lower directions of (b) of Fig. 1) there is the mode of thickness to be formed, and the thickness of the magnetosphere 2 is set as the magnetosphere 2
Surface 2a than weir portion 5 upper surface 5a more be located at the surface sides 1a size.
To maintain the position of magnetic substance using the solidification of bonding agent, bonding agent is coated with and is impregnated in reinforcement magnetosphere 2
The magnetosphere coated face 3 of cloth 1.In addition, the magnetosphere 2 of present embodiment is cured by being mixed with the bonding agent of ferromagnetic powder
And it is formed.As the ferromagnetic powder mixed in bonding agent, can be used:The metals such as iron, nickel;The metal oxides such as ferrite.
Since ferromagnetic powder is mixed in bonding agent, magnetosphere 2 is adsorbed in magnet made of bonding agent solidification.By by magnetic
Body 14 is configured at upper mold 11 (shaping mould 10) (with reference to Fig. 3), and magnetosphere 2 is made to be adsorbed in magnet 14, can will reinforce cloth 1 and fix
In upper mold 11.
As bonding agent, can be used selected from natural polymers such as natural rubbers;Melmac, carbamide resin,
Phenolic resin, vinyl acetate resin, ethylene vinyl acetate resin, epoxy resin, cyano-acrylate resin, acrylic acid
The synthetic resin such as resin;The synthetic macromolecular compounds such as the synthetic rubber such as neoprene, nitrile rubber, butadiene-styrene rubber, silicon rubber

It wants, curing agent, crosslinking agent, filler, tackifier, pigment etc. can be added.In addition, bonding agent can be used when in use by two kinds of liquid
Two fluidity bonding agents of body mixing.When using two fluidity bonding agents, ferromagnetic powder is mixed in the side in two kinds of liquid
.
The bonding agent that magnetosphere 2 is blended with ferromagnetic powder by using glue gun (glue gun) is coated with
(magnetosphere formation process) is formed in magnetosphere coated face 3.Since magnetosphere 2 is the bonding agent for being mixed with ferromagnetic powder
Cure, therefore can make to assign magnetic operation (operation for forming magnetosphere 2) simplicity to reinforcing cloth 1.Thereby, it is possible to carry
Height assigns magnetic workability to reinforcing cloth 1.It is soaked with bonding agent further, since containing between the fiber for reinforcing cloth 1, therefore is passed through
Its Anchoring Effect, magnetosphere 2 can be adhered to magnetosphere coated face 3 (reinforcing cloth 1) securely.
In addition, magnetosphere 2 is not limited to the coating using glue gun, hairbrush coating can also be utilized, sprayed,
It is coated on the transfer (coating) of the bonding agent in coining face, impregnates various means such as (d ipping) and the surface shape in built in items
At.Bonding agent can be simply coated on any position for reinforcing cloth 1 (built in items) by each means.
Since magnetosphere coated face 3 is formed as surrounding by the region that weir portion 5 surrounds, operating personnel is coated
When operation, the position of magnetosphere coated face 3 becomes clear.Therefore, it is possible to form magnetic in the correct position for reinforcing the surface 1a of cloth 1
Property layer 2.It is flowed out outside the region for the 2 magnetropism layer coated face 3 of magnetosphere having been coated with furthermore it is possible to use weir portion 5 limits.Therefore,
Compared with the case where not forming weir portion 5, it is readily able to increase the thickness of magnetosphere 2, it is thus possible to material cost is reduced, and
And it can ensure adsorption capacity to magnet 14.
In addition, as the mark for the position for being coated with magnetosphere 2 and in reinforcing cloth 1 and opening up the existing product of hole punching,
There are problems that the magnetosphere having been coated with 2 flows before curing and is leaked out from hole punching to outside.In contrast, according to this reality
Mode is applied, the flowing (outflow) of magnetosphere 2 is limited using weir portion 5.Furthermore it is possible to eliminate hole punching, and can reduce corresponding
Working hour, and manufacturing cost can be inhibited.
Since magnetosphere 2 is to be mixed with the bonding agent of ferromagnetic powder to cure, ferromagnetic can be utilized
The color of powder colours magnetosphere 2.As a result, due to can by aberration with visual confirmation magnetosphere coated face 3 whether
It is formed with magnetosphere 2, therefore can inhibit to forget coating or twice coating etc..
Then, with reference to Fig. 3, the fixed upper mold 11 for reinforcing cloth 1 is illustrated.Fig. 3 is (one of shaping mould 10 of upper mold 11
Point) upward view.
As shown in figure 3, shaping mould 10 is for making 21 molding mold of seat cushion, by upper mold 11 and lower die (not shown) structure
At.Upper mold 11 is the mold of the side for 23 side of the back side (with reference to Fig. 5) to form pad main body 22, and forming surface 12 is formed in the bottom of die cavity 13
Face (face of Fig. 3 papers inboard).Upper mold 11 is aluminium alloy system, and in many places of forming surface 12, embedment has magnet 14 (permanent magnet).
Magnet 14 is the component for being formed in the magnetosphere 2 for reinforcing cloth 1 (referring to Fig.1) using magnetic-adsorption.In addition, magnet 14 is upper
It is formed at each the three of the top both sides of mould 11 and at each the one of the central both sides nearby of upper mold 11.
Then, with reference to Fig. 4 and Fig. 5, the manufacturing method of seat cushion 21 is illustrated.(a) of Fig. 4 is the reinforcement of stacking keeping
The enlarged partial sectional view of cloth 1, (b) of Fig. 4 are that the partial enlargement of the reinforcement cloth 1 when taking out the reinforcement cloth 1 of stacking keeping cuts open
View, Fig. 5 are the sectional views of the seat cushion 21 of left and right directions.
First, to forming weir portion 5 (stage portion formation process) to reinforcing cloth 1 by mold 30.It is formed by stage portion
Process and be formed in the reinforcement cloth 1 in weir portion 5, magnetosphere 2 is coated on magnetosphere coated face 3 (magnetosphere formation process).It is logical
Cross magnetosphere formation process and be coated with the reinforcement cloth 1 of magnetosphere 2 before the solidification of magnetosphere 2, as shown in (a) of Fig. 4 according to
Secondary overlapping keeping.
Then, in the state of opening upper mold 11 relative to lower die (part for shaping mould 10), make the magnetic of reinforcement cloth 1
Property layer 2 be adsorbed in the magnet 14 for being embedded to upper mold 11, be fixed on upper mold 11 (fixed step) so that cloth 1 will be reinforced.
It will be reinforced by fixed step after cloth 1 is fixed on upper mold 11, it will be as the foaming synthesis of the raw material of pad main body 22
Resin material (the liquid raw material of polyurethane) injects lower die, and coordinates upper mold 11 and mold, and then makes its foaming (molding work
Sequence).After the hardening for carrying out the stipulated time, die sinking demoulds molding pad main body 22.As a result, foamed synthetic resin material impregnated throughout
Cure in reinforcement cloth 1, is integrally bonded at the back side 23 of pad main body 22 and reinforces cloth 1.It is can be obtained as a result, in foaming synthesis tree
22 integration of pad main body of fat has the seat cushion 21 for reinforcing cloth 1.
According to the manufacturing method of the seat cushion 21, since the magnetosphere 2 formed in magnetosphere coated face 3 (reinforcing cloth 1) is mixed
Conjunction has the bonding agent of ferromagnetic powder to cure, therefore can make to assign magnetosphere coated face 3 magnetic operation simplicity.
Further, since not only in magnetosphere coated face 3 containing bonding agent is soaked with, the inner wall 5b in weir portion 5, which also contains, is soaked with bonding agent, therefore viscous
It connects agent promptly to cure, and the area for playing Anchoring Effect expands, magnetosphere 2, which is also correspondingly more firmly adhered to, reinforces cloth 1.
Therefore, in the operation from magnetosphere formation process to fixed step, can inhibit magnetosphere 2 position offset or from reinforce cloth
1 falls off.
In the pre- manufacturing (magnetosphere formation process) for reinforcing cloth 1, even if in the case where cloth 1 is reinforced in stacking keeping,
Also as described above, due to the surface 2a of magnetosphere 2 be located at than weir portion 5 upper surface 5a closer to reinforce cloth 1 the surface sides 1a (with
Height more than the surface 2a of magnetosphere 2 projects weir portion 5), therefore bonding agent magnetosphere 2 before curing can be inhibited to be transferred to
It is laminated in the reinforcement cloth 1 of top (the upper direction of (a) of Fig. 4).
In addition, by being equipped with weir portion 5 from reinforcement cloth 1, as shown in (b) of Fig. 4, the reinforcement cloth 1 that keeping will be laminated takes out
When, it can be slided on the upper surface 5a in the weir portion 5 arranged below for reinforcing cloth 1.Therefore, with reinforce cloth 1 surface 1a
The situation of upper movement is compared, and frictional resistance can be reduced, to be easy the taking-up for carrying out reinforcing cloth 1.Furthermore it is possible to inhibit in quilt
The movement (dragging) of the reinforcement cloth 1 of the lower section configuration of the reinforcement cloth 1 of taking-up, can make laminated arrangement be easy to maintain.
Magnetosphere 2 is formed in a manner of around being surrounded by weir portion 5.Therefore, in fixed step, even if reinforcing cloth 1 and magnetic
In the case that the aberration of property layer 2 is small, operating personnel can also hold the position of magnetosphere 2 on the basis of weir portion 5.Therefore, by
In magnetosphere 2 can be made easily to be adsorbed in magnet 14, therefore it can improve and reinforce installation of the cloth 1 to upper mold 11.
Weir portion 5 is formed with gap 5d between inner wall 5b and outer wall 5c.Therefore, it is possible to inhibit to be impregnated in the magnetic of inner wall 5b
Property layer 2 bonding agent be impregnated with to outer wall 5c and connect with outer wall 5c reinforcement cloth 1 surface 1a.Furthermore it is possible to reduce weir portion 5
Rigidity (make gap 5d be easy to make its reduce or widened Direction distortion), thus enable that reinforce cloth 1 be easy to follow upper mold
11 shape.In addition, reinforcing cloth 1 in the non-formation part (position for forming part and not forming magnetosphere 2 for being formed with magnetosphere 2
Part in the outside from outer wall 5c to prescribed limit) in, be formed as the side i.e. back side opposite with surface 1a (under (b) of Fig. 1
The face of side) it flushes.Therefore, in fixed step, can inhibit between reinforcement cloth 1 (non-formation part) is formed between upper mold 11
Gap.As a result, it is possible to inhibit reinforce cloth 1 from upper mold 11 fall off or the position offset of fixed position.
Since magnetosphere 2 has flexibility, magnetosphere 2 can be made to follow the reinforcement cloth 1 with the flexure for padding main body 22
Deformation.By making magnetosphere 2 follow the deformation of reinforcement cloth 1, the stripping of the magnetosphere 2 of the deformation with pad main body 22 can be inhibited
From, it is damaged.As a result, it is possible to inhibit magnetosphere 2 peeling-off or damaged in the use of seat cushion 21, so as to inhibit magnetic
Layer 2 generates fragment, disintegrating slag or the fragment, disintegrating slag and is stained with the skin of seated person and generates sense of discomfort.
Since weir portion 5 is formed in such a way that the surface 1a from reinforcement cloth 1 is outstanding, pad main body is enclosed in making weir portion 5
In the state of 22, reinforcement cloth 1 can be made integrally to be adhered to the back side 23 of pad main body 22.As a result, it is possible to increase reinforce cloth 1 with
The contact area for padding main body 22 is removed so as to inhibit to reinforce cloth 1 from pad main body 22.
Then, with reference to (e) of (a) to Fig. 6 of Fig. 6, to the reinforcement cloth 201 of second embodiment to sixth embodiment~
601 illustrate.Although in first embodiment, the case where being formed continuously in a circumferential to weir portion 5 under overlook observation, is said
It is bright, but in second embodiment to sixth embodiment, weir portion 205~605 is circumferentially intermittently formed (circumferential at least one
It is to block and formed to divide).
In addition, weir portion 205~605 has section shape ((b) referring to Fig.1) identical with weir portion 5, be formed as weir portion
