Disclosure of the invention

Problems to be solved by the invention

[0008] However, as disclosed in Patent Document 1 described above, in the connecting structure of the cushion body and the cover body, when the seat cover 320 is connected to the cushion body 310, the fixing is attached to the seat cover 320. The member 330 is manually fitted into the holding member 317 of the cushion body 310 by hand. For this reason, it takes a long time to connect and fix the seat cover 320 to the cushion body 310, and a connecting structure that can perform the connecting and fixing work more efficiently is desired.

[0009] Further, in the connection structure of Patent Document 1, forgetting to fit the fixing member 330 into the holding member 317 due to carelessness of the operator, or the fitting of the fixing member 330 is partially incomplete. was there. Therefore, at present, the connection structure of Patent Document 1 is Actually, it is hardly practically used.

[0010] Further, the connection structure disclosed in Patent Document 2 has the same problem.

That is, even in Patent Document 2, it is necessary for the operator to manually insert the hook portions of the hook members attached to the cover body one by one toward the wire of the cushion body. For this reason, it takes time to cover the cover body, and in addition, if the hook member is forgotten to be inserted into the wire, or if the hook member is not sufficiently inserted, the wire locking is not stable. There was a problem!

[0011] For this reason, at present, the cushion body and the cover body are connected and fixed using, for example, a connection structure using a C-ring as introduced in the prior art of Patent Document 2. Yes. That is, the wire is sewn to the cover body and the insert wire is buried in the groove of the cushion body. Then, the cover body is fixedly covered on the surface of the cushion body by connecting the wire disposed on the cover body and the insert wire disposed on the cushion body at a plurality of positions by a C ring.

However, when the cushion body and the cover body are connected and fixed by using such a C-ring, it is necessary to deform the C-ring one by one with a caulking machine to connect the wire and the insert wire. For this reason, there is a problem in that the burden on workers who are troublesome is increased. Also, since the wires and C-rings used for connection are made of metal, when recycling the seat cushion, it is necessary to remove these metal members from the cushion body and cover body, which makes the recycling process complicated. There was also a problem of becoming.

[0013] The present invention has been made in view of the above-described conventional problems, and a specific object of the present invention is to easily and reliably perform the operation of connecting and fixing the cushion body and the cover body in a short time. It is also possible to provide a coupling structure between a cushion body and a cover body that can be easily recycled.

Means for solving the problem

[0014] In order to achieve the above object, the coupling structure of the cushion body and the cover body provided by the present invention is, as a basic configuration, mounted in a concave groove disposed on the surface of the cushion body, and the rail. A first member having a male occlusion or female occlusion and a rail-shaped female occlusion or male occlusion attached to the back surface of the cover covering the surface of the cushion body A cushion body and a cover body, comprising: a second member; and the occlusion element of the first member and the occlusion element of the second member are engaged, and the cover body is connected to the surface of the cushion body. And a slider member that separates the occlusal element of the first member and the occlusal element of the second member into an occlusion Z. The slider member includes the first member and the first member. And an occlusion Z separating means for engaging and separating the bite of the first member and the bite of the second member by sliding along two members, the first member and The second member is configured such that the slider member is detached from the first member and the second member when the bite of the first member and the bite of the second member are separated and when the bite is completed. Composed of the most important features that It is to shall.

[0015] In the connection structure according to the present invention, the first member is erected from a base portion integrally formed continuously with a bottom surface of the concave groove of the cushion body, and a width-direction intermediate portion of the base portion. And a flexible strip-shaped first tape portion formed along the longitudinal direction of the base portion, and the articulator of the first member is an upper end of the first tape portion. The second member that is preferably formed along an edge has a flexible second ribbon tape portion that is attached to the cover body, and the second member has The occlusal is preferably formed along one edge of the second tape portion.

[0016] In the connection structure of the present invention, it is preferable that the first member has a fixing portion that is embedded and integrated so that at least a part of the first member protrudes from the base portion into the cushion body. In this case in particular, it is desirable that the first member has at least one slit extending in the height direction at the fixed portion.

[0017] Furthermore, it is preferable that the articulator included in the first tape portion of the first member is formed to be shorter in the longitudinal direction than the base portion. Furthermore, it is preferable that the first member has at least one sub-base portion extending in the left-right width direction between the articulator and the base portion. ! /.

[0018] Also, in the present invention, the occlusion Z separating means of the slider member is continuous with the first guide gap for guiding the first tape portion of the first member, and the first guide gap. A first guide path for guiding the articulator of the first member, and the second part A second guide gap for guiding the second tape portion of the material, and a second guide path formed continuously with the second guide gap for guiding the bite of the second member, It is preferable that the first guide path and the second guide path join in the middle of the slider member.

[0019] In this case, the interval in the width direction of the second guide path or the first guide path through which the male bite of the slider member is inserted into the female bite is inserted into the female bite. It is preferable that the first guide path or the second guide path is formed narrower than the first guide path or the second guide path. It is preferable that the second guide path is formed to be wide via a step after joining the other guide paths.

[0020] Furthermore, it is preferable that one guide path of the slider member is formed linearly, and the other guide path is joined to the linear guide path at a predetermined angle. It is preferable that at least the first guide gap and the first guide path of a single member are formed in parallel.

The invention's effect

[0021] The coupling structure of the cushion body and the cover body according to the present invention uses the slider member to connect the occluder of the first member attached to the cushion body and the occluder of the second member attached to the cover body. By engaging, the cushion body and the cover body are connected and fixed, and the first member and the second member are not configured integrally, but are configured as independent members. ing.

[0022] Further, the slider member has occlusion Z separating means for causing the occlusal elements of the first and second members to occlude Z from each other. In addition, the first and second members are configured such that the slider member separates the first and second member forces when the first member and the second member are separated and when the occlusion is completed. These first member, second member, and slider member constitute a connector in the connection structure of the present invention.

[0023] In the present invention, when the articulator is engaged by sliding the slider member, the direction in which the first member and the second member move is the vertical direction, and the direction in which the slider member slides is the longitudinal direction. (Front-rear direction), and the direction perpendicular to the vertical direction and the longitudinal direction is the left-right direction Direction (width direction).

[0024] According to such a connection structure of the present invention, the slider member is slid along the first and second members, so that the first member and the second member are shortened. It can be easily bitten in time. Also, a cushion that prevents the occlusion of the occlusal child from becoming partially occluded or the occlusion of the occlusal child from becoming partially occluded due to the carelessness of the operator as in the conventional connection structure. The body and the cover body can be connected and fixed stably and reliably.

[0025] Further, since the slider member separates the first and second member forces after completing the engagement between the first member and the second member, the slider member itself has no influence on the feel and cushioning properties of the cushion body. For example, when a user sits on a vehicle seat, there is no sense of incongruity. Furthermore, since the first and second members can be made of synthetic resin, the metal member does not reside in the cushion body or the cover body. For this reason, the recycling process of the cushion body and the cover body can be easily performed.

[0026] In the present invention, the first member includes a base portion formed continuously on the bottom surface of the concave groove of the cushion body, and a thin strip-shaped first tape portion erected from the base portion. And an articulator formed along the upper edge of the first tape portion. With such a first member, it is possible to stably mount the first member in the groove of the cushion body, and it is also possible to easily engage the second member with the bite. Further, when the cushion body is molded so as to be embedded in the first member casing C as will be described later, the insertion hole of the first member provided in the molding die is inserted into the base portion of the first member. Therefore, it is possible to prevent the molding material force of the cushion body from leaking into the concave groove of the cushion body.

[0027] If the leakage of the molding material can be prevented in this way, the height of the first tape portion provided between the base portion and the bite is made lower in order to smoothly slide the slider. Therefore, the influence of the first member and the second member on the feel of the cushion body and the cushioning property can be reduced, and the material cost can be reduced.

[0028] The second member includes a ribbon-shaped second tape portion and an articulator formed along one end edge of the second tape portion. With such a second member, the second member can be stably attached to the stitched portion provided on the back surface of the cover body, and the first member occlusal It is also possible to easily perform occlusion.

[0029] Further, in the present invention, the first member force is firmly fixed to the cushion body by including the fixed portion that is embedded and integrated at least partially in the cushion body from the first member force base portion. It can be fixed securely. In addition, since the first member has one or a plurality of slits extending in the height direction at the fixed portion, the first member can be easily bent in the longitudinal direction. For this reason, for example, even when the concave groove of the cushion body is curved in the longitudinal direction, the first member can be stably attached to the cushion body in a state of being curved in accordance with the concave groove.

[0030] Furthermore, the articulator of the first member of the present invention has a length in the longitudinal direction shorter than that of the base portion, so that the first member mounted in the concave groove of the cushion body is provided. The slider can be easily inserted into one member, and the first member and the second member can be smoothly engaged. In addition, since the sub-base portion is formed in the left and right width directions on the first tape portion of the first member, the molding of the cushion body is performed when integral molding is performed so that the first member is embedded in the cushion body. It is possible to reliably prevent leakage into the concave groove of the material force cushion body, and it is also possible to reliably position the first member in the molding die.

In the present invention, the slider member occlusion / separation means includes a first guide gap for guiding the first tape portion, a first guide path for guiding the occlusal member of the first member, and a second tape portion. A second guide gap for guiding and a second guide path for guiding the occluder of the second member are provided, and the first and second guide paths are joined in the middle of the slider member. As a result, the first and second member bites are inserted into the slider member, and the slider member is slid along the first and second members. Occlusal with the occlusal child can be performed smoothly.

[0032] In this case, the interval in the width direction (the direction sandwiched between the left and right side plates) in the guide path through which the male bite of the slider member is inserted into the female bite is larger than that in the guide path through which the female bite is inserted. Is also narrowly formed. As a result, when the male occluder is passed through the slider member, the male occluder can be aligned and the male occluder can be surely inserted into the female occlusion and can be engaged.

[0033] Further, the guide path through which the female bite of the slider member is inserted is a guide through which the male bite is inserted. After joining the roads, they are formed wide via a step. As a result, the shoulder loca of the slider member can be easily aligned with the shoulder loca when the shoulder loca penetrates the female occluder in the guide path to the step. In addition, when guiding the male bite to the female bite, the left and right opening widths of the female bite are widened to facilitate insertion of the male bite into the female bite. And the bite between the male bite and the female bite can be performed more smoothly.

In the slider member of the present invention, one guide path is formed linearly, and the other guide path joins the linear guide path at a predetermined angle. Since the occlusal guide part of the slider member is formed in such a shape, the male occlusal can be easily inserted into the female occlusal, and the occlusion between the male occluder and the female occlusal can be made smoother. It can be carried out.

[0035] Further, in the slider member, since at least the first guide gap and the first guide path are formed in parallel, the length of the first tape portion of the first member can be made shorter. It becomes. That is, even if the length of the first tape portion is made shorter, the first member can be smoothly inserted into the occlusal guide portion of the slider member, so that the cushion body and the cover body can be stably connected. it can.

Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings by way of examples.

As shown in FIG. 3, the vehicle seat 1 in which the connection structure of the present embodiment is used includes a seat cushion 2 on which an occupant is seated and a seat back 3 that supports the back of the occupant. The seat back 3 includes a cushion body 4 in which a foamed polyurethane resin is molded into a predetermined shape, and a cover body 5 that covers the surface of the cushion body 4.

[0039] Further, the cover body 5 of the seat cushion 2 is provided with a stitched portion 6 formed in a substantially U shape and a stitched portion 7 formed in a linear shape in the center thereof, and the seat back The cover body 5 of 3 is also provided with a stitched portion 6 'formed in a substantially U shape and a stitched portion 7' formed in a straight line at the center thereof.

On the other hand, on the surfaces of the cushion body 4 of the seat cushion 2 and the seat back 3, the concave grooves 8 are formed so as to correspond to the positions of the stitched portions 6, 6 ′, 7, 7 ′ formed on the cover body 5. Is formed at a predetermined depth. The dimension in the width direction of the concave groove 8 is set to such a size that a slider member 31 described later can be easily inserted and can be easily slid. And, in the seating part of the seat cushion 2 and the backrest part of the seat back 3, the cover body 5 is connected and fixed to the surface of the cushion body 4 having the recessed groove 8 by the connection structure of this embodiment.

In the present embodiment, a hook member is attached to the end portion of the cover body 5, and a hooking portion is disposed on the back surface of the tackle body 4. Therefore, cover the side of the cushion body 4 with the cover body 5 so that the end of the cover body 5 is routed to the back of the cushion body 4 and the hook member of the force bar body 5 is bowed to the bow I hook on the back of the cushion body I. The end of the cover body 5 is fixed to the cushion body 4 by hanging. However, in the present invention, the structure for fixing the end of the cover body 5 is not limited to this, and other structures can be used.

[0042] As shown in Fig. 4, the connecting structure in the present embodiment is a seat cushion 2 as described above. In the seat back 3, the first member 11 mounted in the recessed groove 8 of the cushion body 4 and the second member 21 mounted on the stitched portions 6, 6 ', 7, 7' on the back side of the cover integral 5 The first member 11 and the second member 21 are constituted by a coupling tool including a slider member 31 having an occlusion Z separating means for engaging and separating the first member 11 and the second member 21.

[0043] The first member 11 attached to the cushion body 4 is formed by molding a synthetic resin such as flexible polypropylene as shown in FIG. 8 along the bottom surface 8 'of the base 8, the first tape part 13 erected from the center in the width direction of the base part 12, and the upper edge of the first tape part 13. The formed female bite 14, the sub-base part 15 disposed between the base part 12 and the female bite 14, and the fixing part 16 suspended from the base part 12.

The base portion 12 is formed in a flat plate shape having a width shorter than the width of the concave groove 8 of the cushion body 4, and when the first member 11 is attached to the cushion body 4, the base portion 12 The upper surface of the base plate 12 is exposed at the bottom surface 8 'of the groove, and the lower surface side of the base portion 12 is integrated with the cushion body 4. The width dimension of the base portion 12 is set to be larger than the width dimension of the groove portion 42 provided in the molding die 41 of the cushion body 4 to be described later.

In the present embodiment, the first tape portion 13 is continuously formed along the longitudinal direction of the base portion 12 so as to stand vertically with respect to the base portion 12. Further, the thickness in the width direction of the first tape portion 13 is formed so as to be smaller than an interval between lower flange portions 34b of the slider member 31 described later.

The female articulator 14 is an articulator having a substantially U-shaped cross section and opened upward, and is arranged in a rail shape along the upper end edge of the first tape portion 13. The female bite 14 is formed by bending the left and right tips toward the inside of the female bite 14 at an acute angle when viewed in a cross section. This makes it easy to insert the male bite 23 into the female bite 14 when biting the female bite 14 of the first member 11 and the male bite 23 of the second member 21 described later. After the children 14 and 23 are bitten, the male bite 23 can be prevented from coming out of the female bite 14.

[0047] The sub-base portion 15 extends in the left-right width direction from the first tape portion 13 disposed between the base portion 12 and the female bite 14, and the width dimension of the sub-base portion 15 is , Base part 1 It is shorter than 2 and is set to be substantially equal to the width dimension of the groove portion 42 provided in the molding die 41 of the cushion body 4 to be described later. The first member 11 of the present embodiment has a force in which the sub-base portion 15 is arranged on each of the left and right sides of the first tape portion 13. The present invention is not limited to this, and the base portion 12 and the female occlusion It is also possible to arrange a plurality of sub-base portions 15 between the child 14.

[0048] The fixing portion 16 extends perpendicularly from the central portion in the width direction of the base portion 12 toward the side opposite to the first tape portion 13. The fixing portion 16 is a portion embedded in the cushion body 4 when the first member 11 is attached to the cushion body 4, and the first member 11 is securely fixed to the cushion body 4 and fixed thereto. It is provided to stabilize the state. The shape and size of the fixing portion 16 are not particularly limited, and the formation of the fixing portion 16 can be omitted as necessary.

[0049] After the first member 11 of this embodiment is molded into a predetermined shape as shown in Fig. 1 and before foaming the cushion body 4, as shown in Fig. 7, The cushion body 4 is inserted in advance into each groove portion 42 provided at a predetermined position of the molding die 41. As a result, the first member 11 is integrated with the cushion body 4 in the recessed groove 8 of the cushion body 4 by injecting a resin material into the cavity 43 of the mold 41 and performing foam molding. And can be easily installed.

Note that the molding die 41 shown in FIG. 7 is formed on the lower die 41b in order to insert the first member 11 and the cavity 43 formed between the upper die 41a and the lower die 41b. A groove 42, a hinge 44 that rotates to open the upper mold 41a, a sprue (not shown) that introduces a molding material into the cavity, and a plurality of vent holes 45 that discharge gas when the cushion body 4 is molded. have.

[0051] Further, when foam-molding the cushion body 4, the first member 11 has a width dimension of the base portion 12 larger than that of the groove portion 4 as shown in FIG. Inserted into each groove part 42 of the mold 41 with the top surfaces of both ends in surface contact with the mold 41 and with the sub-base part 15 in contact with the side surfaces of the groove part 42 at both the left and right ends. RU

[0052] Thereby, when the resin material is injected into the cavity 43 of the mold 41, it is possible to prevent the resin material from leaking into the groove part 42 at the base part 12. In addition, even if the grease material leaks into the groove portion 42 from between the base portion 12 and the mold 41, the female occlusal child in the sub-base portion 15 The leakage of the grease material to the side can be reliably prevented.

[0053] In particular, in the present invention, when a plurality of sub-base portions 15 are formed between the base portion 12 and the female occlusal member 14, leakage of the grease material can be prevented more reliably. Therefore, as shown in FIG. 4, the first member 11 attached to the tack member 4 has a height from the bottom surface 8 ′ of the groove 4 of the cushion member 4 to the female bite 14 so that the first member 11 has a first height. The predetermined size can be sufficiently secured without being smaller than the height of the tape portion 13.

Furthermore, in this embodiment, since the left and right ends of the sub-base portion 15 are in contact with the side surfaces of the groove portion of the mold 41, the first member 11 is inserted into the groove portion 42 of the mold 41, thereby The first member 11 can be positioned by the portion 15 so that the first member 11 can be stably disposed at the center in the width direction of the groove portion 42.

In addition, as shown in FIG. 5, the first member 11 of the present embodiment has a first tape portion 13 and a female bite 14 formed on the front end portion and the rear end portion of the first member 11. However, the lengths of the first tape portion 13 and the female bite 14 in the longitudinal direction are shorter than the lengths of the base portion 12 and the fixing portion 16 in the longitudinal direction. In particular, in the present embodiment, the first tape portion 13 and the female occluder 14 are larger than the length in the longitudinal direction of the slider member 31 at the front and rear ends of the first member 11 by the base portion 12 and the fixing portion 16. Is also formed short.

Thus, for example, when the first member 11 and the second member 21 are engaged using the slider member 31, the slider member 31 is connected to the female bite 14 of the first member 11 and the shoulder of the slider member 31. It can be easily inserted into the recessed groove 8 of the cushion body 4 so that the mouth is at the same height. Further, after the first member 11 and the second member 21 are engaged, the slider member 31 can be easily extracted from the concave groove 8 of the cushion body 4.

It should be noted that the connection structure of the present embodiment has been described as a mode in which emphasis is placed on the ease of insertion and extraction of the slider member 31. However, the present invention is not limited to this, and the first tape portion 13 and the female bite 14 may be formed up to the front end and the rear end of the first member 11. In this case, the slider member 31 can be slid by being inserted into the first member 11 using the elasticity of the first member 11. As a result, the cushion body 4 and the cover body 5 can be reliably connected to the front end and the rear end of the concave groove 8.

On the other hand, the second member 21 is made of a flexible polypropylene or the like like the first member 11. It is formed by molding a synthetic resin, and as shown in Fig. 1, the second tape part 22 in the form of a strip and the male occlusion formed in a rail shape along one edge of the second tape part It has a child 23 and a ridge 24 projecting so that the right and left double-sided force of the second tape portion 22 is orthogonal to the second tape portion 22.

[0059] In addition, the second tape portion 22 has a plurality of bending grooves 25 on the left and right surfaces on the other end (the end opposite to the end on which the male bite 23 is formed). The second tape portion 22 is formed so as to be easily bent into a U shape. As a result, the second tape portion 22 can be appropriately bent according to the shape of the stitched portions 6, 6 ', 7, 7' of the cover body 5.

[0060] The male bite 23 is formed in a bowl shape in cross section, and can be stably bitten with the female bite 14 by being inserted into the female bite 14 of the first member 11. . Further, in the present embodiment, the male occluder 23 and the protrusion 24 of the second member 21 are formed so as to have substantially the same width dimension.

As shown in FIG. 4, the second member 21 includes a portion on the other edge side of the second tape portion 22 and stitched portions 6, 6 ′, 7, 7 ′ formed on the cover body 5. By overlapping and sewing, the second member 21 can be easily mounted along the stitched portions 6, 6 ', 7, 7' of the cover body 5.

[0062] Further, as shown in FIG. 2, the slider member 31 is a left and right side plate 32a and a right side plate 32b, guide pillars 33 connecting the left and right side plates 32a and 32b, and left and right side plates as occlusion Z separating means. 32a, 32b includes upper and lower flange portions 34a and 34b extending toward the center in the width direction, and an articulator guide portion 35 formed inside the slider member 31. ing. Further, the slider member 31 has a handle holding portion 38 that is integrally formed on the outer surface side of the left side plate 32a.

[0063] The handle holding portion 38 is formed so that the handle 50 can be freely attached to or detached from the screwed portion. As a result, the handle 50 of the slider member 31 has an appropriate shape such as a curved handle or a grip provided on the handle according to the form of the occlusal or the cross-sectional shape of the groove. It is possible to easily replace the handle that has it. [0064] Note that the handle holding portion 38 of the present embodiment is configured to protrude from the left side plate 32a and have a screwed portion. However, in the present invention, the configuration of the handle holding portion is particularly limited. For example, a handle holding portion formed in a hole shape so that a string or the like can be attached may be adopted. Further, the left and right side plates may be provided with a handle holding means that also has a protrusion or groove force, and the handle may be pivoted by a groove or protrusion corresponding to the handle holding means. Further, the attachment position of the handle holding portion is not limited to the left side plate 32a, and may be integrally formed on the right side plate 32b, the guide column 33, or both the left and right side plates 32a, 32b and the guide column 33.

[0065] Further, a first guide interval 47b having a width larger than the thickness (width dimension) of the first tape portion 13 of the first member 11 is formed between the lower flange portions 34b. The guide interval 47b guides the first tape portion 13, and serves as a guide portion for guiding and assisting the female bite 14 to the guide path 35 (first guide path 35b described later).

[0066] On the other hand, a second guide interval 47a having a width larger than the thickness (width dimension) of the second tape portion 22 of the second member is formed between the upper flange portions 34a. The interval 47a serves as a guide part for guiding the second tape part 22 and guiding and assisting the male bite 23 in the guide path 35 (second guide path 35a described later). In this embodiment, the slider member 31 is formed by molding a synthetic resin. However, the present invention is not limited to this. The slider member may be made of metal, for example.

In the inside of the slider member 31, the articulator guide portion 35 surrounded by the left and right side plates 32a, 32b and the upper and lower flange portions 34a, 34b is formed. The occlusal guide part 35 includes a linear first guide path 35b for inserting the female occlusion element 14 of the first member 11 and a second guide path for inserting the male occlusion element 23 of the second member 21. The second guide path 35a is formed by joining the straight first guide path 35b so that the angle on the guide pillar 33 side becomes an acute angle. In this case, the two ends (openings) of the branching side of the occlusal guide part 35 constitute upper and lower shoulders 36, and the ends (openings) of the side where the occlusal guide part 35 joins are opened. The rear entrance 37 is configured.

If the slider member 31 having such a configuration is used, for example, the female bite 14 of the first member 11 is inserted from the lower shoulder 36 of the slider member 31 and the upper shoulder 36 is inserted. After inserting the male bite 23 of the second member 21, the slider member 31 is slid along the first and second members 11, 21, so that The two parts 21 can be easily engaged with the female bite 14 and the male bite 23.

[0069] In particular, the first member 11 is attached to the cushion body 4, and it is difficult to deform the female bite 14 in the height direction. For this reason, since the first guide path 35b through which the female bite 14 is inserted is formed linearly, the slider member 31 can be slid smoothly.

[0070] Further, in this case, the first and second guide intervals 47b, 47a formed between the upper and lower flange portions 34a, 34b of the slider member 31 are formed so as to be positioned at the center between the left and right side plates 32a, 32b. Yes. Further, the first and second guide intervals 47b, 47a and the occlusal guide part 35 are formed so as to be parallel to each other in the penetration direction.

Accordingly, the height of the first tape portion 13 of the first member 11 (that is, the distance from the base portion 12 to the female bite 14) is made more than necessary than the thickness of the lower flange portion 34b of the slider member 31. The length from the folded portion 26 to the male bite 23 when the second tape portion 22 of the second member 21 is folded in a U shape is set to the upper flange portion 34a of the slider member 31. The slider member 31 can be smoothly slid along the first and second members 11 and 21 without making the thickness larger than necessary. For this reason, it is possible to reduce the size of the connection structure and the material cost.

[0072] Further, in the slider member 31 of the present embodiment, in order to facilitate the insertion of the female bite 14 and the male bite 23 from the upper and lower shoulders 36, the distance between the bite guides 35 toward the shoulder 36 ( That is, the taper portions 40 are formed on the inner surfaces of the left and right side plates 32a and 32b so that the distance between the left and right side plates 32a and 32b increases gradually.

[0073] Further, in the occlusal guide part 35 of the slider member 31, the second guide path 35a through which the male occlusion 23 inserted from the upper shoulder 36 is engaged with the female occlusion 14 is provided as a female occlusion. It is formed with a narrower interval in the width direction than the linear first guide path 35b through which 14 is inserted. As a result, the male bite 23 guided by the bite guide part 35 of the slider member 31 is reliably aligned in the width direction, and the male bite 23 is smoothly inserted into the female bite 14. As a result, work efficiency is improved.

[0074] In addition, in the slider member 31, a first guide path 35b through which the female bite 14 is inserted is proposed. A step 39 is formed between the inner pillar 33 and the rear opening 37. The guide path 35c on the shoulder 36 side of the step 39 is elastically deformed at the U-shaped tip of the female bite 14 and It has a cross-sectional shape that corresponds to the cross-sectional shape of the female bite in the state of being pressed (see Fig. 6 (a)). As a result, the slider member 31 aligns the female bite 14 inserted into the bite guide part 35 from the shoulder 36, and the male bite 23 of the female bite 14 is inserted into the male bite 14. Since it can be located directly under the tip of 23, the bite of the female bite 14 and the male bite 23 can be more reliably performed.

[0075] Further, the guide path 35d on the rear opening 37 side with respect to the step 39 has a cross-sectional shape in which the upper side is formed wider than the cross section of the guide path 35c on the shoulder opening 36 side (Fig. (See 6 (b)). As a result, when the male bite 23 is inserted into the female bite 14, the left and right tip sides of the female bite 14 can be opened to enlarge the opening width. The female bite 14 and the male bite 23 can be stably inserted by smoothly inserting into the inside. In the present invention, the width in the width direction sandwiched between the left and right side plates 32a, 32b of the first guide path 35b only needs to be formed wider on the rear opening 37 side than the shoulder opening 36 side. 3 9 is composed of an inclined surface.

[0076] Then, according to the connection structure of the present embodiment having the above-described configuration, the first member 11 of the cushion body 4 and the second member 21 of the cover body 5 that are configured in an independent state are connected. The force bar body 5 can be connected and fixed to the cushion body 4 by performing the following operation using the slider one member 31.

That is, first, the slider member 31 having the handle 50 attached to the handle holding portion 38 is inserted into the concave groove 8 of the cushion body 4, and the slider member 31 is shown by a two-dot chain line in FIG. The first tape portion 13 and the female bite 14 are formed in front of the first member 11, and the lower shoulder 36 of the slider member 31 and the height of the female bite 14 are held in space. . At this time, the front end force slider member 31 of the female bite 14 is inserted into the shoulder 36.

[0078] Next, the male bite 23 and the protrusion 24 of the second member 21 attached to the cover body 5 are inserted from the upper shoulder 36 of the slider member 31, and the male bite 23 is inserted into the bite guide part 35. Until it reaches the junction of the first guideway 35b and the second guideway 35a. At this time, the protrusion 24 of the second member 21 contacts the upper flange portion 34b of the slider member 31, and the height of the male bite 23 is increased. Alignment in the direction. Further, by inserting the female bite 14 and the male bite 23 into the slider member 31 in this manner, the position in the width direction of the female bite 14 and the position in the width direction of the male bite 23 are changed to the slider member. It can be adjusted to the approximate center of 31.

Thereafter, the female bite 14 and the male bite 23 can be engaged with each other by sliding the slider member 31 along the first and second members 11 and 12 toward the rear end side. Here, the occlusion of the female bite 14 and the male bite 23 will be described in detail with reference to FIG. In FIG. 6, (a) is a cross-sectional view showing a cross section taken along line VI (a) —VI (a) shown in FIG. 2 (b) when the bite is bitten. Fig. 2 is a sectional view showing a section taken along line VI (b) -VI (b) shown in Fig. 2 (b), and Fig. 2 (c) is a front view when the slider member is viewed from the rear opening side. .

[0080] When the slider member 31 is slid with the female bite 14 and the male bite 23 inserted into the bite guide part 35 of the slider member 31, the female bite 14 and the male bite 23 are engaged. Before the operation, as shown in FIG. 6 (a), the female bite 14 has its left and right side surfaces slidably contacted with the inner wall of the guide path 35c. The second guide path 35a is in sliding contact with the inner wall. As a result, the relative positions of both the bites 14 and 23 are adjusted so that the distal end of the male bite 23 is located immediately above the center of the female bite 14, and the male bite 23 is moved to the female bite. 14 can be easily inserted.

[0081] Further, the slider member 31 is slid to the rear end side of the first and second members 11, 21, and the female bite 14 and the male bite 23 are continuously moved to the rear port 37 side of the slider member 31. invite. As a result, when the female bite 14 passes through the wide guide path 35d, the male bite 23 is gradually lowered toward the female bite 14 as shown in FIG. Since the left and right side portions of the female bite 14 can be pushed and widened by the tip of the male bite 23, the tip of the male bite 23 can be smoothly inserted into the female bite 14.

[0082] Then, by guiding the female bite 14 and the male bite 23 to the rear opening 37 of the slider member 31, as shown in FIG. 6 (c), the tip of the male bite 23 is moved to the female bite. It can be completely inserted into 14 and can be engaged with female bite 14 and male bite 23.

[0083] By sliding the slider member 31 to the rear end side of the first and second members 11 and 12 in this way, the female bite 14 and the male bite 23 are moved over the entire length. Easily bitten Thus, the cushion body 4 and the cover body 5 can be stably connected and fixed. Further, in the connection structure of the present embodiment, neither the female bite 14 of the first member 11 nor the male bite 23 of the second member 12 is provided with a stopper for stopping the sliding of the slider member 31. For this reason, after the slider one member 31 is engaged with the female bite 14 and the male bite 23, the rear end force of the first and second members 11, 12 is also extracted, and the first and second members 11, 12 are removed. Can be disengaged from. As a result, the feel of the cushion body 4 and the deterioration of the texture due to the slider member 31 remaining in the concave groove 8 do not occur.

[0084] It should be noted that the slider member 31 is temporarily slid to the front end side of the first and second members 11, 12 before or after being detached from the first and second members 11, 12. The bite female bite 14 and the male bite 23 can be easily separated.

As described above, according to the connection structure of the present embodiment, by sliding the slider member 31, the first member 11 attached to the cushion body 4 and the second member 21 attached to the cover body 5 Can be easily bitten in a short time. For this reason, compared with the conventional connection structure, it is possible to reduce the troublesomeness of the work, and further, forgetting to bite the bites by the operator's carelessness, and the occlusion of the bite is partially unsatisfactory. The cushion body 4 and the cover body 5 can be stably and surely connected and fixed by preventing them from becoming perfect.

It should be noted that the present invention is not limited to the embodiments described above, and has various configurations as long as it has substantially the same configuration as the present invention and has the same effects. It can be changed. For example, in the above-described embodiment, a connection structure for connecting the cushion body 4 and the cover body 5 in the seat cushion 2 and the seat back 3 of the vehicle seat 1 is described. However, the connection structure according to the present invention is not limited to this, but can be similarly applied to the case where the cushion body and the cover body are connected in a vehicle seat or furniture seat having other shapes. it can.

In addition, as a first modification of the above-described embodiment, as a first member to be mounted on the cushion body 4, for example, as shown in FIG. 9 (a), the fixing portion 16 ′ has a height direction from the lower end. It is also possible to use the first member 11 ′ in which a plurality of slits 17 extending linearly are formed. In this way, if the first member 11 ′ has a plurality of slits 17 in the fixing portion 16 ′, for example, as shown in FIG. 9 (b), the bottom surface of the concave groove 8 disposed on the surface of the cushion body 4. 8 'is curved in a convex shape in the longitudinal direction Even in this case, the first member 11 ′ can be easily and stably attached to the concave groove 8 in a state where the first member 11 ′ is curved in accordance with the curvature of the concave groove bottom surface 8.

Furthermore, as a second modification, as shown in FIG. 10, the occlusal member formed on the first member 11 and the second member 21 are formed on the connection structure of the above-described embodiment (see FIG. 4). It is also possible to configure the connection structure by reversing the relationship with the bite. That is, in the present invention, the male member 23 and the protrusion 24 are formed on the first member 11 attached to the cushion body 4, and the female member 14 is formed on the second member 21 attached to the cover body 5. Also good. Also by adopting such a connection structure of the second modification, the same effect as in the above embodiment can be obtained.

Note that in the case of the second modification, the configuration of the occlusal guide portion 35 of the slider member 31 is changed from that of the above embodiment, for example, the male occlusal 23 inserted from the lower shoulder 36. It is necessary to form a narrower gap in the width direction than the guide path through which the female articulator 14 is inserted. The

Furthermore, in the present invention, the configurations of the base portion 12, the sub base portion 15, and the fixing portion 16 of the first member 11 to be attached to the cushion body 4 are shown in, for example, FIGS. 11 (a) to (e). It is also possible to make various changes as described (Modification 3 to Modification 7). For example, as in Modification 3 shown in FIG. 11 (a), the formation of the sub-base portion 15 is omitted, and the length of the base portion 12a in the left-right width direction is longer than that of the first member 11 of the above embodiment. Then, the first member 11 a for embedding and integrating the left and right tip portions of the base portion 12 a in the cushion body 4 may be attached to the cushion body 4. In the case of the first member 11a of Modification 3, the base part 12a itself serves as a fixing part, and effectively prevents the molding material from leaking into the groove part 42 of the mold 41. Can

Is formed. Providing such a sub-base portion 15b also ensures positioning of the first member 11 in the groove portion 42 of the mold 41 when the cushion body 4 is foam-molded, as in the above embodiment. Can do. At the same time, even if the resin material is injected into the cavity of the mold 41, it is possible to reliably prevent the resin material from leaking over the sub-base part 15b to the female occlusal 14 side. The

[0092] The first member 11c of Modification 5 shown in FIG. 11 (c) is formed so that the sub-base portion 15 is omitted and the base portion 12c is curved so as to have a U-shaped cross section. Yes. In addition, a fixing portion 16c that is partially embedded in the cushion body 4 is formed at the tip of the base portion 12c. Further, the first member l id of Modification 6 shown in FIG. 11 (d) is formed so that the sub base portion 15 is omitted and the base portion 12d itself is curved toward the cushion body 4 side. Te! In this modified example 6, the base portion 12d itself is configured to serve as the base portion 11 and the sub-base portion 15 of the above-described embodiment alone.

[0093] Further, in the first member l ie of Modification 6 shown in Fig. 11 (e), the base portion 12e and the sub-base portion 15e are inclined from the first tape portion 13 toward the cushion body 4 side.
