The present invention relates to a suspension structure of a skin (seat cover, trim cover) that covers the surface of a cushion pad (cushion material) of a seat for automobile applications, and particularly holds a suspension member provided on the skin side and the suspension member thereof. Therefore, the present invention relates to a holding locking member provided on the cushion pad side (sometimes referred to as a hanging member including a hanging member, a holding locking member, and an inner wire), and a seat hanging structure using them.

Conventionally, as a method of fixing the main part in the covering of a seat for automobile applications, a hanging method of suspending the skin through a hanging wire to a C ring bound to the back surface of the seat or a pad, or a trim rubber has been used. A trim rubber method of passing through a C ring bound to the back surface of the skin and a surface fastener method of attaching the skin to a surface fastener are widely adopted. In these hanging methods, a groove-shaped hanging portion is formed in the cushion material as a structure for attaching the trim cover (skin) to the foam cushion material (cushion pad) molded into the seat shape. A structure in which a part of the trim cover is inserted into the hanging portion and fastened to the cushion material to hang the trim cover is often used.

As such a hanging structure, Japanese Patent No. 5665115 (Patent Document 1) has a hanging cloth (hanging bag) sewn on the back surface of a trim cover (seat cover) and is embedded in the hanging cloth and a cushion material. Disclosed is a seat cover mounting structure in which a pad wire (seat back wire) is suspended by hoggling with a C ring.
In view of the fact that it is necessary to sew a hanging cloth on the back surface of the trim cover in the seat cover mounting structure disclosed in Patent Document 1, Japanese Patent Application Laid-Open No. 2016-202673 (Patent Document 2) provides such hanging. Disclosed is a hanging structure of a sheet that reduces the labor and cost of sewing cloth. The seat suspension structure disclosed in Patent Document 2 is a suspension structure for a seat that suspends and supports a trim cover with respect to a seat member constituting the seat, and is for suspension arranged on the surface side of the trim cover. It is characterized by having a linear suspension member of the above, and a fastening member for fastening the linear suspension member in a state of being inserted into a groove for suspension formed in the seat member to the seat member.

Further, in view of the fact that it is necessary to use a tool in the sheet suspension structure disclosed in Patent Document 2, Japanese Patent Application Laid-Open No. 2017-006601 (Patent Document 3) suspends the sheet without using a tool. Disclose the hanging structure of the sheet that can be squeezed. The seat suspension structure disclosed in Patent Document 3 is a suspension structure for a seat that suspends and supports a trim cover with respect to a seat member constituting the seat, and is for suspension arranged on the surface side of the trim cover.

Japanese Patent No. 5665115 Japanese Unexamined Patent Publication No. 2016-20673 Japanese Unexamined Patent Publication No. 2017-006601

By the way, the seat hanging structure disclosed in Patent Documents 2 and 3 does not require sewing a hanging cloth on the trim cover with respect to the seat cover mounting structure disclosed in Patent Document 1. Even if it is advantageous, the linear suspension member is arranged on the surface side of the trim cover, and is further wrapped by the surface side of the trim cover and cannot be directly visually confirmed. Therefore, the linear suspension member is attached to the seat member by the fastening member. The workability of fastening to is not preferable. On the other hand, in the seat cover mounting structure disclosed in Patent Document 1 and the seat suspension structure of Patent Document 2, a tool is required because the hog ring is performed by using the C ring, and it is shown in FIG. 5 of Patent Document 1. It is necessary to curl both ends of the seat back wire (inner wire) as described above, and as shown in FIG. 2 of Patent Document 2 and Patent Document 3, both ends of the linear suspension member are easy to handle during work and are longitudinal. There is a problem that it is necessary to round (curl) both ends in order to make it difficult to move in the direction.

In light of these issues, instead of using a C-ring and an inner wire with rounded ends and a linear suspension member, a line along the end of the trim cover so that the linear suspension member can be seen directly. It is conceivable to provide a shape suspension member and suspend the seat by locking the linear suspension member to a fastening member provided with a locking portion as disclosed in Patent Document 3.
However, in contrast to the case where the linear suspension member is locked to the locking portion of the fastening member together with the trim cover (by winding the trim cover), only the linear suspension member is fastened (without involving the trim cover). When locked to the locking portion of, even if the linear suspension member does not come out of the locking portion of the fastening member or does not come out of the locking portion of the fastening member, the locking portion (engages the trim cover). Since only the linear suspension member is locked (without any problem), there may be a problem that the linear suspension member shakes in the locking portion due to rattling. Further, in order to solve these problems, if the margin dimension for locking the linear suspension member to the locking portion of the fastening member is reduced, the linear suspension member is locked to the locking portion of the fastening member. Workability at the time is reduced.

The present invention has been developed in view of the above-mentioned problems of the prior art, and an object of the present invention is that the workability of suspending the skin to the cushion pad of a seat for automobile applications is good (at least the work man-hours).

[Hanging member]
The hanging member 100 is a member that suspends the skin 32 on the cushion pad (cushion material) 34. The suspending member 100 is roughly composed of three parts, a linear suspending member 200 provided along the end of the skin 32, and a cushion pad along the linear longitudinal direction (see FIG. 3). It is composed of an inner wire 300 provided in 34, and a holding locking member 400 including a wire holding portion 450 for holding the inner wire 300 and a locking portion 410 for locking the suspension member 200. Then, as shown in FIG. 3A, a plurality of holding locking members 400 in which the inner wire 300 is held by the wire holding portion 450 are connected at intervals in the longitudinal direction, and as shown in FIG. 3C. Each holding locking member 400 at intervals locks the hanging member 200 and suspends the skin 32. Here, the locking portion 410 of the holding locking member 400 includes a disconnection preventing portion 412 for preventing the locked suspension member 200 from coming off the locking portion 410, and a locking portion where the locked suspension member 200 is locked. It includes a fluctuation prevention unit 414 that prevents fluctuations in the 410.

More specifically, as shown in FIGS. 4 (B) and 4 (C) and FIG. 5, the cross-sectional shape of the suspension member 200 is a rounded (here formed by a curve 214) substantially V-shape. The shape of the opening side (straight line 212 side) is closed by a curve or straight line (here, straight line 212) that is gentler than the V-shape (curve 214 side indicated by curvature R (R is not always constant)). The skin 32 is sandwiched on the opening side (straight line 212 side) having a substantially V shape. In the holding locking member 400, in order from the direction in which the suspending member 200 approaches (the direction indicated by the black arrow in the figure), the locking portion 410 is prevented from coming off, the locking portion 410 is prevented from fluctuating, and the wire holding portion is held. It is equipped with 450. The cross-sectional shape of the pull-out prevention portion 412 includes a locking inner surface 412B for locking a gentle curved line or a straight line (here, a straight line 212), and an inclined outer surface 412A having a shape for guiding the tip 218 of the suspension member 200. To prepare for. On the other hand, the cross-sectional shape of the fluctuation prevention portion 414 is such that when the suspension member 200 advances toward the wire holding portion 450 (when the suspension member 200 advances in the direction indicated by the white arrow in the figure), the outer surface of the suspension member 200 (here, the curvature). The outer surface formed by the curve 214 of R (R is not always constant) abuts and includes a rounded protrusion 414A that prevents its progress.

More specifically, resin covers 320 are provided at both ends of the inner wire 300. The resin cover 320 is integrally molded with the inner wire main body 310. Therefore, it is not necessary to bend (curl) both ends of the wire body 310.
More specifically, the suspension member 200 and the holding locking member 400 are made of resin, and the locking portion 410 of the holding locking member 400 is flexible. As described above, the suspending member 200 and the holding locking member 400 that are locked to each other are made of resin and have good familiarity with each other, and are easily locked and disengaged. Further, in order for the locking portion 410 to have flexibility, the suspending member 200 can be easily engaged by bending and deforming the locking portion 410 (the portion of the pair of locking claws forming the disconnection prevention portion 412). It can be stopped and detached. The work of deforming the resin locking portion 410 can be performed with bare hands, and the work of suspending or removing the skin (seat cover, trim cover) 32 can be performed without using a tool. Make it possible. As described above, the portion of the pair of locking claws forming the disconnection prevention portion 412 of the locking portion 410 is flexible at the portion for locking the suspending member 200, and the suspension member 200 is provided by the pair of locking claws. Is sandwiched and locked.

Regarding the material of the hanging member, it is preferable that the holding and locking member 400 is made of a flexible resin, and the hanging member 200 is not made of resin but made of iron or aluminum. It may be made of a metal such as, rubber, or the like, but in the present embodiment, it will be described as being made of a resin such as polypropylene or polyethylene as described above. Further, the wire body 310 of the inner wire 300 is easy to work in the cushion material manufacturing process by following the process of manufacturing the cushion material by positioning and insert molding with a magnet provided in the mold as in the conventional case. It is preferable that it is made of a metal that reacts with a magnetic material (magnet) so as not to reduce the temperature.

With reference to FIG. 5, the wire holding portion 450 of the holding locking member 400 constituting the hanging member 100 will be described in detail.
As the wire holding portion 450 of the holding locking member 400, a wire holding hole 452 having a diameter that can hold and hold the wire main body 310 of the inner wire 300 is provided so as to penetrate in the longitudinal direction. By inserting and fitting the wire body 310 into the wire holding hole 452, the wire body 310 of the inner wire 300 is sandwiched and held by the wire holding portion 450. If the diameter of the wire holding hole 452 is made large enough so that the holding locking member 400 can move on the wire main body 310 in the longitudinal direction, the position of the holding locking member 400 deviates from the design position during the hanging operation. It is not preferable because it will end up. In the state shown in FIG. 3B, more specifically, in a state where a plurality of holding locking members 400 in which the inner wire 300 is held by the wire holding portion 450 are connected at intervals in the longitudinal direction, urethane foaming is performed. The inner wire 300 (here, the wire body 310 is made of a metal that reacts with a magnetic material (magnet)) is positioned by a magnet provided in the mold, and urethane is foamed in the mold to form an inner wire. 300 is embedded by insert molding. In this respect, there is no difference from the conventional manufacturing process of the cushion material of the seat, and the workability at the time of manufacturing the cushion material is not deteriorated.

That is, to briefly explain the foaming process of the cushion material, (1) the mold is coated with a mold release agent, and (2) as an auxiliary material, in addition to the backing material, it is in the state shown in FIG. 3 (B). The inner wire 300 and the holding locking member 400 in a state where a plurality of holding locking members 400 in which the inner wire 300 is held by the wire holding portion 450 are connected at intervals in the longitudinal direction are connected by a magnet provided in the mold. Position and set in the mold, (3) put the urethane raw material into the mold, (4) close the mold to foam the urethane raw material, (5) open the mold and open the inner wire. The cushion material into which the 300 and the holding locking member 400 are insert-molded is taken out. The foaming process of such a cushion material is no different from the conventional foaming process, and the workability at the time of manufacturing the cushion material is not deteriorated.

Next, with reference to FIG. 5, the function of preventing the hanging member 200 from coming off by the locking portion 410 of the holding and locking member 400 constituting the hanging member 100, and the function of preventing the hanging member 200 from coming off, and the fluctuation prevention portion 414 of the locking portion 410. The fluctuation prevention function of the suspension member 200 will be described in detail.
As mentioned above
The cross-sectional shape of the suspension member 200 is a rounded (formed by a curve 214) substantially V-shape, and the opening side (straight line 212 side) is a gentler curve than the substantially V-shape (curve 214 side). Or with a shape closed by a straight line (here straight line 212),
The cross-sectional shape of the pull-out prevention portion 412 (a pair of locking claws) includes a locking inner surface 412B for locking a gently curved or straight line (here, a straight line 212), and the tip 218 of the suspension member 200. Equipped with an inclined outer surface 412A having a shape that induces
The cross-sectional shape of the fluctuation prevention portion 414 is such that when the suspension member 200 advances toward the wire holding portion 450 (when the suspension member 200 advances in the direction indicated by the white arrow in the figure), the outer surface of the suspension member 200 (here, the curve 214). It is provided with a rounded protrusion 414A which is in contact with the outer surface (formed by) to prevent its progress.

The locking inner surface 412B of the locking inner surface 412 of the locking portion 410 of the conventional holding locking member 400 is as shown by a dotted line in FIGS. 4 and 5 (or like a horizontal straight line in FIGS. 4 and 5). ) The shape did not match the curve or straight line (here, straight line 212) on the opening side (straight line 212 side) in the cross-sectional shape of the suspension member 200. On the other hand, in the present embodiment, the holding locking member holds the locking inner surface 412B that matches the shape of the gently curved or straight line (here, the straight line 212) portion of the suspension member 200 and locks the hanging member 200. The locking portion 410 of the 400 is provided with a disconnection prevention portion 412. Therefore, it is possible to extremely effectively prevent the suspension member 200 once locked to the locking portion 410 of the holding locking member 400 from coming off.

Further, the fluctuation prevention portion 414 as shown in FIGS. 4 and 5 was not formed in the locking space 414S of the locking portion 410 of the conventional holding locking member 400. On the other hand, in the present embodiment, when the suspension member 200 advances toward the wire holding portion 450 (when the suspension member 200 advances in the direction indicated by the white arrow in the figure), the outer surface of the suspension member 200 (here,). The outer surface formed by the curve 214 having a curvature R (R is not always constant) abuts and includes a rounded protrusion 414A that prevents its progress. Therefore, it is possible to extremely effectively prevent the suspension member 200 once locked to the locking portion 410 of the holding locking member 400 from fluctuating.

In particular, a shape including the distance L (1) and the distance L (2) shown in FIG. 5 and the curvature R (R is not always constant) on the outer surface (outer surface formed by the curve 214) of the suspension member 200. By setting it appropriately, it is possible to suppress the shaking to the minimum while maximizing the removal prevention function. For example, when L (1) = 0, L (2) has a slight value, so that the shake prevention function can be maximized and the shaking can be suppressed to the minimum. In this case, it is needless to say that the workability of locking the suspension member 200 to the holding / locking member 400 and the workability of disengaging the suspension member 200 from the holding / locking member 400 are not deteriorated.
[Hanging structure and hanging method]
The seat suspension structure 500 and the suspension method using the suspension member 100 having the above configuration will be described with reference to FIGS. 1 to 5.

As described above, the suspension structure 500 is spaced apart from the inner wire 300 in the longitudinal direction inside the cushion pad 34 in the suspension groove portion (suspension groove 36) formed in the cushion pad 34. A wire holding portion 450 of the plurality of holding locking members 400 is provided, a locking portion 410 of the plurality of holding locking members 400 is provided in the groove portion (hanging groove 36), and the groove portion (hanging groove 36) is provided. The skin 32 is inserted, and the suspension member 200 provided along the end portion on the skin 32 side is locked by the locking portion 410.

Such a suspension structure 500 whose cross section is shown in FIG. 2 (A) is compared with a conventional suspension structure using the suspension member 201, the inner wire 301, and the C ring 401 shown in FIG. 2 (B). No tools are required, the number of assembly steps is small (as in the hanging method shown below), and workability is preferable.
By using the hanging member 100 according to the present embodiment, it is not necessary to curl both ends of the inner wire. Further, since the size of the holding locking member 400 in the longitudinal direction can be easily reduced as compared with the conventional clip, it becomes easy to follow the inner wire bent in advance, and the seat design has a fine curved shape. Can be easily dealt with.

Further, the method of suspending the sheet (suspension procedure) will be briefly described below.
First, a linear suspension member 200 is provided along the end of the skin 32. The suspension member 200 is moved together with the skin 32 in the direction indicated by the black arrow shown in FIGS. 3 and 4, and is inserted into the suspension groove 36.
At this time, the inner wire 300 and the holding locking member 400 are connected by insert molding to a plurality of holding locking members 400 in which the inner wire 300 is held by the wire holding portion 450 at intervals in the longitudinal direction. In the state shown in (B), the wire body 310 of the inner wire 300 and the resin cover 320 are embedded in the cushion material 34 in a portion deep from the bottom of the recess forming the hanging groove 36 by a predetermined amount. In the groove portion (the portion of the hanging groove 36 that is not inside the cushion material 34), the locking portions 410 of the plurality of holding locking members 400 are provided. In this state, the suspension member 200 is inserted into the groove portion (suspension groove 36) together with the skin 32, and the suspension member 200 provided along the end portion on the skin 32 side is locked by the locking portion 410.

Similarly, the work of locking the suspension member 200 by the holding locking member 400 is repeated at other predetermined locations. By the above work, the hanging work of locking the hanging member 200 to the locking portion 410 of the holding locking member 400 and suspending the skin 32 to the backrest 30 is completed, and the hanging structure according to the present invention is obtained. It can be realized.
The work procedure for removing the skin 32 is the reverse of the above-mentioned hanging method.

In this case, in the method of suspending the sheet disclosed in Patent Document 3, a linear suspension member (corresponding to the suspension member 200 in the present application) and an insert wire (corresponding to the suspension member 200 in the present application) are provided by a resin clip (corresponding to the holding locking member 400 in the present application). When fastening (corresponding to the inner wire 300 in the present application), both work of locking the linear suspension member to the locking portion of the resin clip and work of hooking the fastening portion of the resin clip to the insert wire are required. However, in the hanging method in the hanging structure according to the present invention, only one work of locking the hanging member 200 by the locking portion 410 of the holding locking member 400 is sufficient, and moreover, only one work is required.
