Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above configuration, a plurality of locking portions are arranged along the opening edge of the recess, and each of the plurality of locking portions is individually attached to the interior material main body portion via screws. For this reason, there is a problem that the working hours related to the attachment of the locking portion increase.

[0005] The technology disclosed in this specification has been completed based on the above circumstances, and an object thereof is to provide a vehicle interior material capable of reducing the working hours when attaching a locking portion for holding a net member to the interior material main body portion. <D000029>

Means for Solving the Problems

[0006] As a means to solve the above problems, the interior material for vehicles disclosed herein comprises a plate-shaped interior material body, a net member disposed on the vehicle interior side surface of the interior material body, and a reinforcing member attached to the vehicle exterior side surface of the interior material body, wherein the surface of the reinforcing member on the interior material body side has a plurality of protrusions that project toward the interior material body, each of the plurality of protrusions is inserted through each of the plurality of through holes formed in the interior material body, and the protruding end of the protrusion is disposed on the vehicle interior side relative to the interior material body and is a locking portion that locks into the net member.

[0007] By providing reinforcing members, the rigidity of the parts of the interior material body corresponding to the net member can be increased, preventing deformation of the interior material body when inserting or removing items between the net member and the interior material body. The net member is held in place by the locking parts, which are the protruding ends of the protruding parts, and multiple protruding parts are formed on the reinforcing members. Therefore, by attaching the reinforcing members to the interior material body, multiple protruding parts can be fixed to the interior material body. This reduces the amount of work required compared to a configuration in which multiple protruding parts (and thus locking parts) are each attached to the interior material body. In addition, the protruding parts are inserted through holes formed in the interior material body. This allows the protruding parts to be held within the through holes, thus increasing the rigidity of the protruding parts compared to a configuration in which the protruding parts are attached to the surface of the interior material body, and allowing the net member to be held more securely.

[0008] Furthermore, a recess opening toward the net member is formed on the vehicle interior side of the interior material body, the net member is arranged to cover at least a portion of the recess, the recess is composed of a bulge formed by causing a portion of the interior material body to bulge toward the reinforcing member, and the reinforcing member may have a fitting recess into which at least a portion of the bulge is fitted.

[0009] The interior material body has a recess, which increases the gap between the net member and the interior material body, allowing larger items to be accommodated between the net member and the interior material body. Furthermore, the interior material body has a bulge, which increases its rigidity. In addition, the reinforcing member has a fitting recess into which a portion of the bulge fits, which increases the rigidity of the reinforcing member and allows for more reliable reinforcement of the bulge. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide an interior material for vehicles that can reduce the number of work steps required when attaching a locking portion for holding a net member to the main body of the interior material. [Brief explanation of the drawing]

[0012] One embodiment of the present invention will be described with reference to Figures 1 to 10. In this embodiment, a vehicle room partition trim 20 is exemplified as an interior material for a vehicle. As shown in Figure 1, the room partition trim 20 has the function of separating a passenger compartment 12 in which a seat 11 is located where an occupant sits, from a storage compartment 14 in which equipment 13 such as a battery mounted on the vehicle is located. The equipment 13 is covered from the front side of the vehicle (left side in Figure 1) by a metal panel member (not shown), and the room partition trim 20 is positioned to cover the panel member from the front side of the vehicle.

[0013] As shown in Figures 2 and 4, the room partition trim 20 comprises a plate-shaped trim body 21 (interior material body), a net member 40 arranged on the interior side surface of the trim body 21 (the side facing the vehicle interior, the side facing the seat 11), and reinforcing members 60, 91, 92, 93, 94, 95 attached to the exterior side surface of the trim body 21 (the side facing the vehicle interior, the side facing the equipment 13).

[0014] The trim body portion 21 is formed by integrally molding a sheet of synthetic resin (e.g., polypropylene) and a surface material (decorative member) by hot pressing. When the trim body portion 21 is manufactured by press molding, it is difficult to form ribs on the surface of the trim body portion 21 to ensure rigidity. Therefore, in this embodiment, rigidity is ensured by attaching reinforcing members 60, 91, 92, 93, 94, and 95 to the trim body portion 21.

[0015] As shown in Figures 2 and 3, recesses 22 and 23 are formed on the lower part of the interior-facing surface of the trim body 21, opening towards the net member 40. Recess 22 is approximately square in shape when viewed from the front. Recess 23 is formed in the part of the trim body 21 corresponding to the lower half of the opening edge of recess 22. The depth of recess 23 is smaller than the depth of recess 22, and it is formed in a stepped manner, continuing from recess 22.

[0016] As shown in FIG. 2, the net member 40 has a horizontally long rectangular shape and is stretchable. The net member 40 is fitted into the concave portion 23 and is arranged so as to cover the lower portion of the concave portion 22. Thereby, an article can be accommodated between the trim main body portion 21 and the net member 40. As shown in FIG. 5, the concave portion 22 is constituted by a bulging portion 24 formed by bulging a part of the trim main body portion 21 toward the reinforcing member 60 side (outside of the vehicle compartment). Further, the concave portion 23 is constituted by a bulging portion 25 formed by bulging a part of the trim main body portion 21 toward the reinforcing member 60 side.

[0017] As shown in FIGS. 5 and 6, the reinforcing member 60 includes a plate-shaped reinforcing member main body portion 61, an annular rib 62 formed on the inner surface of the reinforcing member main body portion 61 on the vehicle compartment side, and a lattice-shaped rib 63 formed on the outer surface of the reinforcing member main body portion 61 on the outside of the vehicle compartment. As shown in FIG. 10, the reinforcing member main body portion 61 has a fitting concave portion 64 into which the lower portion of the bulging portion 24 is fitted. Thereby, the reinforcing member main body portion 61 is arranged so as to cover the lower portion of the bulging portion 24 from the outside of the vehicle compartment. The fitting concave portion 64 is formed by bulging a part of the reinforcing member main body portion 61 toward the outside of the vehicle compartment. As shown in FIG. 6, the reinforcing member main body portion 61 has a bottom wall portion 61A and standing wall portions 61B, 61C, 61D that constitute the fitting concave portion 64. A through hole 65 is formed at the boundary portion between the bottom wall portion 61A and the lower standing wall portion 61B.

[0018] As shown in FIG. 10, in the region corresponding to the inside of the rib 62 on the inner surface of the reinforcing member main body portion 61 on the vehicle compartment side, it is adhered to the outer surface of the trim main body portion 21 on the outside of the vehicle compartment by an adhesive 68 (for example, a hot melt adhesive or the like). By applying the adhesive 68 inside the annular rib 62, the adhesive 68 can be surely applied to a predetermined location.

[0019] As shown in Figure 6, a plurality of protrusions 66, 67 are integrally formed on the surface of the reinforcing member body 61 facing the trim body 21, projecting toward the trim body 21. As shown in Figure 7, the plurality of protrusions 66, 67 have the function of holding the outer peripheral end 41 of the net member 40. The plurality of protrusions 66, 67 are arranged on the opening edge of the fitting recess 64. Of the plurality of protrusions 66, 67, the upper protrusion 66 is inserted through a through hole 26 formed in the bottom wall of the recess 23 in the trim body 21, as shown in Figure 8.

[0020] The protruding end of the protruding portion 66 is positioned on the interior side of the vehicle relative to the trim body portion 21. A recess 66A is formed at the protruding end of the protruding portion 66, opening diagonally upward. As shown in Figure 8, the corner portion 41A of the outer peripheral end portion 41 of the net member 40 is fitted into the recess 66A. As a result, the opening edge of the recess 66A becomes a locking portion 66B that engages with the corner portion 41A of the net member 40. In other words, the protruding end of the protruding portion 66 becomes a locking portion 66B that engages with the net member 40.

[0021] Of the multiple protrusions 66, 67, the lower protrusion 67, as shown in Figure 6, comprises a base portion 67A located at the base end and a locking portion 67B protruding from the base portion 67A. As shown in Figure 8, the base portion 67A is inserted through a through hole 27 formed in the trim body portion 21. The locking portion 67B is the protruding end of the protrusion 67 and is bent in an L-shape. The locking portion 67B is located on the interior side of the vehicle relative to the trim body portion 21. The locking portion 67B locks onto the outer peripheral end 41 of the net member 40.

[0022] As shown in Figure 6, of the three protrusions 67 arranged in the vehicle width direction, the tips of the locking portions 67B on the two end protrusions 67 are positioned so that they face diagonally downwards. As a result, as shown in Figure 8, the base portion 67A and the locking portion 67B form a recess 67D that opens diagonally downwards. The corner portion 41B of the outer peripheral end 41 of the net member 40 is housed in the recess 67D.

[0023] As shown in Figure 6, of the three protrusions 67 arranged in the width direction of the vehicle, the tip of the locking portion 67B of the central protrusion 67 is positioned so that it faces upward. As a result, as shown in Figure 9, the base portion 67A and the locking portion 67B form a recess 67D that opens upward. The lower edge portion 41D of the outer peripheral end 41 of the net member 40 is housed in this recess 67D. As a result, the base end portion 67E of the locking portion 67B supports the portion 41D of the net member 40 from below. This prevents the portion 41D of the net member 40 from sagging due to the weight of the item when an item is placed in the recess 22. In addition, a projection 69 is formed at the tip of the locking portion 67B, as shown in Figure 9. This prevents the outer peripheral end 41 of the net member 40 from coming out of the recess 67D.

[0024] The reinforcing member 60 is made of, for example, synthetic resin and can be manufactured by injection molding. The protrusion 66 having the recess 66A can be molded using a slide mold. In contrast, as shown in Figure 9, a through hole 67F is formed in the base portion 67A of the protrusion 67. As a result, the protrusion 67 can be molded without using a slide mold.

[0025] Next, the effects of this embodiment will be described. The room partition trim 20 of this embodiment comprises a plate-shaped trim body portion 21, a net member 40 disposed on the interior side surface of the trim body portion 21, and a reinforcing member 60 attached to the exterior side surface of the trim body portion 21. Multiple protrusions 66, 67 are formed on the surface of the reinforcing member 60 facing the trim body portion 21, and each of the multiple protrusions 66, 67 is inserted into each of the multiple through holes 26, 27 formed in the trim body portion 21. The protruding ends of the protrusions 66, 67 are positioned on the interior side relative to the trim body portion 21 and are locking portions 66B, 67B that engage with the net member 40.

[0026] By providing the reinforcing member 60, the rigidity of the portion of the trim body 21 corresponding to the net member 40 can be increased, thereby suppressing deformation of the trim body 21 when inserting or removing items between the net member 40 and the trim body 21. The net member 40 is held in place by the locking portions 66B and 67B, which are the protruding ends of the protruding portions 66 and 67, and multiple protruding portions 66 and 67 are formed on the reinforcing member 60. Therefore, by attaching the reinforcing member 60 to the trim body 21, multiple protruding portions 66 and 67 can be fixed to the trim body 21. This reduces the amount of work required compared to a configuration in which multiple protruding portions 66 and 67 (and thus locking portions 66B and 67B) are each attached to the trim body 21. The protruding portions 66 and 67 are inserted through through holes 26 and 27 formed in the trim body 21. As a result, the protrusions 66 and 67 can be held within the through holes 26 and 27, which increases the rigidity of the protrusions 66 and 67 compared to a configuration in which the protrusions 66 and 67 are attached to the surface of the trim body 21, and allows the net member 40 to be held more securely.

[0027] Furthermore, a recess 22 opening towards the net member 40 is formed on the interior side of the trim body 21, and the net member 40 is arranged to cover at least a part of the recess 22. The recess 22 is composed of a bulge 24 formed by causing a part of the trim body 21 to bulge towards the reinforcing member 60, and the reinforcing member 60 has a fitting recess 64 into which at least a part of the bulge 24 is fitted.

[0028] The presence of a recess 22 in the trim body 21 allows for a larger gap between the net member 40 and the trim body 21, enabling the storage of larger items between the net member 40 and the trim body 21. Furthermore, the presence of a bulge 24 in the trim body 21 increases its rigidity. Moreover, the presence of a fitting recess 64 in the reinforcing member 60, into which a portion of the bulge 24 fits, increases the rigidity of the reinforcing member 60 and allows for more reliable reinforcement of the bulge 24.

[0029] Furthermore, a recess 23 is formed on the interior-facing surface of the trim body 21 into which the net member 40 is fitted. This makes it possible to bring the surface of the net member 40 and the interior-facing surface of the trim body 21 closer to being flush, thereby improving the aesthetic appearance.
