  In Patent Documents 1 to 3, elastic materials and mesh-like materials are used as tonneau covers and sunshades. However, when mesh-like materials are used, the inside of the luggage compartment can be visually recognized through the materials, but the shielding effect There is a problem of lowering. In addition, when using a knitted fabric with fine elasticity, it is necessary to open the tonneau cover every time you want to check the inside of the luggage, but it is difficult to check while driving the car. There is a problem.

  Therefore, an object of the present invention is to provide a vehicle interior tool that has a shielding effect and ensures visibility using a knitted fabric sheet body made of a light-transmitting three-dimensional knitted fabric.

  In the vehicle interior tool according to the present invention, a plurality of stitch rows knitted by chain stitches in the warp direction are arranged at predetermined intervals in the weft direction, and a pair of insertion yarns cross each other between adjacent stitch rows. The connecting yarns are alternately knitted in the warp direction between the pair of ground structures formed in a lattice pattern by the warp direction stitch rows and the weft direction insertion yarns and the stitch rows of the ground textures. A knitted fabric sheet body having a plurality of light-shielding layers formed in a planar shape and arranged at predetermined intervals in the weft direction, and a support fixed so as to be held over at least the entire width of the knitted fabric sheet body along the stitch row. In the state where the support body is attached to the inside of the vehicle and the knitted fabric sheet body is stretched, the stitch rows of the knitted fabric sheet body are linearly arranged so that the light shielding layer has a predetermined inclination angle. Incident in a predetermined direction by setting And having a light-shielding property and breathability for. Further, the support body is fixed along the stitch row on both sides in a direction orthogonal to the stitch row of the knitted fabric sheet body, and covers the rear space of the rear seat inside the vehicle with the knitted fabric sheet body. It is attached to the inside of a vehicle. Furthermore, the support body is formed in a frame shape so as to hold the periphery of the knitted fabric sheet body, and is attached to a position facing a window portion inside the vehicle.

The yarn is knitted in a warp direction and knitted to have a plurality of light shielding layers arranged in the weft direction at predetermined intervals, and the knitted fabric sheet body is stretched in a state where the knitted fabric sheet body is stretched. Since the stitch rows are arranged in a straight line and the light shielding layer is set at a predetermined inclination angle, there is a shielding effect against light incident from a direction orthogonal to the light shielding layer, and along the light shielding layer. Light is transmitted from the direction and has visibilityFor this reason, it is impossible to look inside the vehicle through the knitted fabric sheet body together with the light shielding effect by attaching the light incident from the rear outside the vehicle in a direction perpendicular to the light shielding layer of the knitted fabric sheet body. A visual blocking effect is obtained. On the other hand, when the knitted fabric sheet body is viewed from the rear seat inside the vehicle, since it is in the direction along the light shielding layer, the light is transmitted and has visibility, and the luggage loaded inside the vehicle through the knitted fabric sheet body, etc. Can be easily confirmed.

  In addition, since the pair of ground structures are formed in a lattice pattern and the light shielding layers are arranged at a predetermined interval between the stitch rows of the ground texture, they have sufficient air permeability and have light shielding properties by the light shielding layers. However, it does not interfere with the air flow.

  Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 is a plan view relating to an interior fitting for a vehicle for covering a luggage compartment or the like inside the vehicle. In this example, the vehicular interior fitting covers a luggage compartment disposed behind a rear seat in a vehicle such as an automobile from above, and is generally called a tonneau cover. The tonneau cover 1 is configured by fixing plate-like supports 11 and 12 to both sides of a knitted fabric sheet body 10.

  FIG. 2 is a cross-sectional view taken along the line AA of FIG. The knitted fabric sheet body 10 is composed of ground structures 101 and 104 and a light shielding layer 107, and the entire constituent yarn is subjected to shape stabilization processing such as heat setting processing and resin processing, and a predetermined interval is provided between the ground textures 101 and 104. It is designed to be held open.

  FIG. 3 is a partially enlarged perspective view of the knitted fabric sheet body 10, and FIG. 4 is a partially enlarged plan view of the knitted fabric sheet body 10. In the ground structure 101 on one surface side, stitch rows 102 knitted by chain stitches in the warp direction are arranged at predetermined intervals in the weft direction, and the insertion yarns 103 are alternately knitted into the adjacent stitch rows 102 by a predetermined length. It is formed in a planar shape. Therefore, the ground structure 101 is formed in a lattice pattern by the stitch row 102 extending linearly in the warp direction and the insertion yarns 103 arranged so as to be swung across the adjacent stitch row 102 in the weft direction. ing.

  Similarly, in the ground structure 104 on the other surface side, stitch rows 105 knitted by chain stitches in the warp direction are arranged at predetermined intervals in the weft direction, and inserted into adjacent stitch rows 105 alternately by a predetermined length. 106 is knitted into a flat surface. Accordingly, the ground structure 104 is formed in a lattice pattern by the stitch rows 105 extending linearly in the warp direction and the insertion yarns 106 arranged so as to be swung over the adjacent stitch rows 105 in the weft direction. ing.

  The stitch row 102 of the ground structure 101 is disposed opposite to the stitch row 105 of the ground structure 104, and the ground structures 101 and 104 are disposed so as to overlap each other when viewed from the front.

  The light shielding layer 107 is formed in a plane shape in the warp direction by alternately knitting connecting yarns between the stitch row 102 of the ground texture 101 and the stitch row 105 of the ground texture 104. Are arranged so as to be parallel to each other. The connecting yarns forming the light shielding layer 107 are densely arranged to provide light shielding properties, and the light shielding properties can be further improved by using bulky yarns such as crimped yarns as the connecting yarns.

  The light shielding layer 107 connects between the stitch row 102 of the ground texture 101 and the stitch row at a position shifted from the stitch row 105 of the ground texture 104, which are opposed to each other. One of the adjacent light shielding layers 107 is connected to the stitch row 102 of the ground structure 101 arranged oppositely, and the other is connected to the stitch row 105 of the ground structure 104 arranged oppositely. Therefore, the light shielding layer 107 is exposed on the entire surface in a plan view (indicated by the line-of-sight direction S1) and an angle orthogonal to the light-shielding layer 107 (indicated by the line-of-sight direction S2) shown in FIG. 1, and the entire surface of the knitted fabric sheet body 10 is shielded from light. And has a shielding effect as a blindfold. When viewed from an angle along the surface direction of the light shielding layer 107 (indicated by the line-of-sight direction S3), light can be transmitted from between the light shielding layers 107, and the inside of the luggage compartment can be visually recognized through the light shielding layer 107. .

  The supports 11 and 12 are arranged on both sides of the knitted fabric sheet body 10 along the stitch row 102 of the ground texture 101 and the stitch row 105 of the ground texture 104, and are fixed by sewing, bonding, or the like. The supports 11 and 12 are attached over the entire width of the knitted fabric sheet body 10 along the stitch rows 102 and 105, and are formed in a plate shape having substantially the same thickness as the knitted fabric sheet body 10. As the supports 11 and 12, for example, a plate-shaped core material covered with synthetic leather or a synthetic resin sheet may be used.

  A pair of hook members 13 are attached to the support body 11 at the boundary with the knitted fabric sheet body 10, and the support body 11 can be attached to the inside of the vehicle by hooking the hook member 13 on a locking portion inside the vehicle. it can. Moreover, two pairs of hook members 14 are attached to the support body 12 at the end portions, and the support body 12 can be attached by hooking the pair of hook members 14 to the rear seat.

  FIG. 5 is an explanatory view showing a state in which the tonneau cover 1 is attached to the inside of the vehicle M. First, the support member 12 is attached by hooking the hook member 14 to a pair of support rods that project to the lower part of the headrest H provided in the rear seat R. Then, the support 11 is pulled backward while being gripped by hand, and the hook member 13 is hooked on a locking fitting provided at the rear part of the vehicle M so that the knitted fabric sheet 10 is stretched in a substantially horizontal direction. Install the tonneau cover 1. The rear of the rear seat of the tonneau cover 1 is a luggage compartment B, and the attached tonneau cover 1 is set so as to cover the upper portion of the luggage compartment B. Since the knitted fabric sheet body 10 is set in a stretched state, a lightweight object such as an umbrella, a hat, or a ball can be placed on the upper surface, and the storage space can be increased by dividing the luggage compartment into two stages. In addition, it becomes possible to separately store fragile items and frequently used items.

  FIG. 6 is an explanatory diagram relating to shielding and visibility with the tonneau cover 1 attached. As shown in FIG. 4, by attaching the light shielding layer of the knitted fabric sheet body 10 so as to incline upward toward the front side, light incident from the rear window M1 (indicated by a dotted arrow) Since the light enters the direction orthogonal to the light shielding layer, the light is not shielded and enters the luggage compartment. Further, when looking into the inside of the luggage compartment from the outside of the vehicle M, the line of sight is blocked by the light shielding layer, so it is difficult to visually recognize the luggage accommodated inside, which is preferable for crime prevention. On the other hand, when the knitted fabric sheet body 10 is viewed from the rear seat side, the line-of-sight direction is substantially along the light shielding layer, so that light can be transmitted and the inside of the luggage compartment can be easily visually confirmed. .

  Moreover, since the space | gap is formed between the light shielding layers, the knitted fabric sheet | seat body 10 is equipped with favorable air permeability, without preventing air distribution | circulation.

  As described above, according to the present invention, it is possible to obtain a vehicular interior accessory that has both a shielding effect, good visibility, and air permeability.

  FIG. 7 is a schematic diagram showing the knitting structure of the ground structure 101 of the knitted fabric sheet body 10. Between adjacent stitch rows 102, a pair of insertion yarns 103a and 103b are alternately knitted into the stitch row 102 by a predetermined length while being swung in the weft direction. The insertion yarn 103 is knitted in a lattice shape. The pair of insertion yarns 103a and 103b are swung in the weft direction opposite to each other so as to intersect each other between the stitch rows 102. Therefore, there are two insertion yarns 103a and 103b in the warp direction stitch row 102. Since the knitted fabrics are double woven and the insertion yarns 103 are crossed in the weft direction, the strength of the entire knitted fabric is improved, the shape retention is improved, and the light transmission of the ground structure 101 is ensured. It is like that. The ground organization 104 also has the same knitting organization as the ground organization 101.

  FIG. 8 is a knitting structure diagram relating to a light-transmitting three-dimensional knitted fabric for knitting the knitted fabric sheet body 10. L1 and L2 are insertion yarns 103 of the ground texture 101, and L3 is a stitch row 102 of the ground texture 101 knitted by chain stitch. As shown in the figure, L1 and L2, which are a pair of insertion yarns 103, are alternately knitted into adjacent stitch rows 102 by a predetermined length, and are laid so as to intersect between adjacent stitch rows 102.

  L4 and L5 are knitting yarns for knitting the ears at both ends, and are used to fix and stretch both ends of the knitted fabric knitted in the form stabilizing process to the conveying pins, as will be described later. L6 is a connecting yarn, which is knitted alternately in the stitches 102 and 105.

  L7 is a stitch row 105 of the ground texture 104 knitted by chain stitch, and L8 and L9 are insertion yarns 106 of the ground texture 104. As with the ground structure 101, the pair of insertion yarns L 8 and L 9 are alternately knitted into the adjacent stitch row 105 by a predetermined length, and are laid so as to intersect between the adjacent stitch rows 105.

  As the knitting yarns of the ground tissues 101 and 104, recycled fibers represented by rayon, natural fibers represented by cotton, semi-synthetic fibers such as acetate, polyester-based synthetic fibers represented by polyethylene terephthalate, and nylons. An aliphatic polyamide-based synthetic fiber or a mixed fiber thereof can be used, and may be either a long fiber yarn or a spun yarn, and is not particularly limited.

  As the connecting yarn, a bulky yarn such as a crimped yarn using a synthetic fiber such as a polyester synthetic fiber typified by polyethylene terephthalate and an aliphatic polyamide synthetic fiber typified by nylon is preferable. By using such yarns, when the light shielding layer is knitted in a planar shape, there is no gap between the yarns, and the light shielding property can be improved.

  FIG. 9 is an explanatory diagram relating to a process for stabilizing the form of the light-transmitting three-dimensional knitted fabric F knitted as shown in FIG. The knitted fabric is dyed and refined as necessary. Then, the knitted fabric is conveyed by a roller and is carried into a liquid tank 200 that stores a resin liquid, and the knitted fabric is impregnated with a resin material. As the resin material to be impregnated, acrylic resin, urethane resin, polyester resin, silicon resin, melamine resin and the like are preferable.

  The impregnated knitted fabric is pinched by the squeezing roller 201 to squeeze excess resin liquid and carry it into the dryer 202. The dryer 202 dries in a state in which the ears at both ends of the knitted fabric are stretched by hanging on the pins. In the drying step, it is preferable to dry at 150 ° C. for 2 to 3 minutes. Since the both ends of the knitted fabric are pulled and dried in a stretched state, the inserted yarn that is stretched so as to intersect between adjacent stitch rows becomes a tension state, and the stitch rows of the texture are straight in the warp direction. The insert thread is linearly extended in the weft direction and formed in a lattice shape, and the shape is stably processed while the pair of ground structures are held at a predetermined interval.

  As the shape stabilization processing, heat setting processing may be used in addition to the resin processing described above. In the case of heat setting processing, a known heat setting process may be performed by heating the entire knitted fabric in a state where the knitted fabric is stretched.

  FIG. 10 is a plan view relating to a modified example of the tonneau cover 1 described above. In this example, the fastener 15 is attached along the boundary portion between the knitted fabric sheet body 10 and the support body 11, and the fastener 16 is similarly attached to the boundary portion between the knitted fabric sheet body 10 and the support body 12. . Then, by opening and closing the fastener 15 or 16 with the tonneau cover 1 stretched, it is possible to insert and remove articles by inserting a hand into the luggage compartment while the tonneau cover 1 is stretched.

  FIG. 11 is a plan view of another vehicle interior fitting. In this example, the vehicle interior tool is a sunshade 17 that is disposed opposite to a sunroof M2 provided in an upper opening of the vehicle M. In the sunshade 17, a knitted fabric sheet 18 similar to the knitted fabric sheet 10 is stretched inside a rectangular frame 19. FIG. 12 is an explanatory view showing a state in which the sunshade 17 is attached to the inside of the vehicle. The frame body 19 is detachably attached to a ceiling portion inside the vehicle, and is set so that the knitted fabric sheet body 18 is disposed to face the sunroof M2.

  FIG. 13 is an enlarged cross-sectional view of the sunshade 17 in the attached state. The sunshade 17 is attached so that the light shielding layer of the knitted fabric sheet 18 is inclined upward as it goes to the front side of the vehicle, and wind from the front generated during operation passes through the knitted fabric sheet 18 smoothly. Installed inside the vehicle. Further, direct sunlight incident on the sunroof M2 from the rear of the vehicle is shielded by the light shielding layer. Therefore, a sunshade having good air permeability and light shielding properties can be obtained. Moreover, the light shielding effect can be enhanced while maintaining the air permeability by arranging the sunshades in a double manner so that the inclination direction of the light shielding layer of each knitted fabric sheet body is opposite.

  Such a sunshade 17 may be detachably attached to the window portion on the side surface of the vehicle. In that case, if the light shielding layer of the knitted fabric sheet 18 is attached so as to incline outward as it goes to the vehicle front side, wind from the front can be smoothly introduced into the vehicle when the window is opened. it can. Further, if the light shielding layer is attached so as to incline as it goes upward, a high light shielding effect can be obtained.

  FIG. 14 is an explanatory diagram showing a case where the sunshade 20 is rotatably attached to the upper part of the driver's seat inside the vehicle windshield M3. Similar to the sunshade 17, the sunshade 20 is constructed by stretching a knitted fabric sheet body 21 on a frame body 22. Like the conventional sunshade, the upper end portion is pivotally supported by a rotating shaft body and pivots up and down. It is attached as possible.

  FIG. 15 is an explanatory diagram regarding a state in which the sunshade 20 is operated. As shown in FIG. 15A, when direct sunlight enters from the front with the sunshade 20 stored along the ceiling inside the vehicle, as shown in FIG. When the sunshade 20 is rotated and installed, the direct sunlight is blocked by the light shielding layer. Further, when direct sunlight enters from above, as shown in FIG. 15C, if the sunshade 20 is rotated and installed along the windshield, the knitted fabric sheet body 21 blocks direct sunlight. In addition, the driver can visually recognize the external situation from between the light shielding layers, and can obtain a good field of view while avoiding direct sunlight.
