Description

[Technical field]

[0001] The present invention relates to a vehicle interior member structure. [Background technology]

[0002] Conventionally, when a luggage holding member such as a rope is used to hold luggage in the vehicle interior, a vehicle is known that is provided with a hook in the vehicle interior for fastening the luggage holding member. For example, Patent Document 1 discloses a rope hook fixed to the luggage compartment floor of an automobile via a bracket. The rope hook is exposed to the vehicle interior from a cutout formed in a trim member arranged on the upper part of the luggage compartment floor. The cutout of the trim member is formed in a shape that allows the rope hook to freely appear and disappear. When the rope hook protrudes from the cutout, the free end side of the tongue formed by the cutout is raised together with the rope hook, and when the rope hook is buried below the cutout, the cutout and the free end of the tongue are in close contact with each other.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-86301 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a cutout portion for exposing the rope hook to the inside of the vehicle cabin is formed in the trim member as in the above conventional structure, when the rope hook protrudes from the cutout portion, the components arranged on the outside of the trim member (for example, body frame components such as the luggage compartment floor and cushioning materials such as felt) may be visible through the gap between the cutout portion of the trim member and the free end of the tongue piece, which may detract from the aesthetic appearance of the vehicle cabin. In addition, there is a risk that road noise and other sounds propagated to the outside of the trim member may leak into the vehicle cabin through the above gap. Furthermore, there is also a problem that the rope hook and the trim member are composed of separate members, which is likely to lead to a decrease in production efficiency, and there is room for improvement.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide an interior component structure for a vehicle that can be produced with high production efficiency, can engage a luggage holding member, and can suppress deterioration of the aesthetic appearance of the interior of the vehicle and noise leakage. [Means for solving the problem]

[0006] In order to achieve the above object, one aspect of the present invention provides a resin-molded interior member structure for a vehicle. The interior member structure for a vehicle includes a hook portion engageable with a luggage holding member for holding luggage inside the vehicle compartment, and a panel portion having a support surface for supporting the hook portion on the interior side of the vehicle compartment and forming at least a part of an inner wall surface facing the interior side of the vehicle compartment, the hook portion and the panel portion being integrally molded. The panel portion has a recessed portion recessed toward the exterior side of the vehicle compartment on the panel surface on the interior side of the vehicle compartment, and the support surface is provided on a bottom surface of the recessed portion. The recess portion has a peripheral wall portion extending from the peripheral edge of the support surface toward the interior of the vehicle cabin and connecting to the panel surface, and the peripheral wall portion has an inner inclined portion extending at an angle approaching the hook portion as it moves from the panel surface toward the exterior of the vehicle cabin, and the interior end of the hook portion is located in a position that overlaps with the exterior end of the inner inclined portion when viewed from a direction parallel to the support surface. Effect of the Invention

[0007] In the vehicle interior member structure according to the present invention, the hook portion that can engage with the luggage holding member is integrally molded in a state of being supported by the support surface of the panel portion, and the hook portion is exposed to the interior of the vehicle. Therefore, the member arranged on the exterior side of the interior member is not visible from the interior side, and it is possible to suppress deterioration of the aesthetic appearance of the interior of the vehicle and to suppress leakage of road noise and other noise into the interior of the vehicle. In addition, the integral molding of the hook portion and the panel portion makes it possible to improve production efficiency. Furthermore, a recess that is recessed toward the exterior of the vehicle is formed on the panel surface of the panel portion, and the support surface of the hook portion is provided on the bottom surface of the recess. As a result, a part of the tensile load transmitted from the hook portion to the support surface is borne by the peripheral wall of the recess, so that the connection rigidity between the hook portion and the panel portion can be improved and it is possible to prevent the hook portion from jumping out toward the interior of the vehicle due to the tensile load. In addition, by arranging the end of the inner inclined portion of the peripheral wall portion on the outside of the vehicle cabin and the end of the hook portion on the inside of the vehicle cabin at a position that overlaps when viewed from a direction parallel to the support surface, it is possible to eliminate the hook portion protruding into the vehicle cabin, and to prevent interference between the hook portion and other components, such as cargo, placed in the vehicle cabin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 is a side view of the rear of a vehicle to which an interior member structure for a vehicle according to one embodiment of the present invention is applied, as viewed from inside the vehicle. Fig. 2 is a side view showing a state in which an interior member 1 in Fig. 1 has been removed. In the drawings referred to in this specification, the arrow Fr direction indicates the front of the vehicle in the vehicle longitudinal direction, and the arrow U direction indicates the upper side of the vehicle in the vehicle vertical direction. The arrow I direction indicates the direction toward the interior of the vehicle, and the arrow O direction indicates the direction toward the exterior of the vehicle.

[0010] As shown in Fig. 1, an interior member 1 to which the structure according to this embodiment is applied includes a hook portion 10 and a panel portion 20 that are integrally molded using a resin material. The hook portion 10 is configured to be engageable with a luggage holding member (not shown) for holding luggage inside the vehicle cabin. The luggage holding member includes, for example, a string-like member such as a rope, or a hook molded into various shapes. The luggage is held inside the vehicle cabin by engaging the luggage holding member with the hook portion 10 of the interior member 1 by tying, hanging, or fitting it together.

[0011] The panel portion 20 has a support surface 21 that supports the hook portion 10 on the vehicle interior side. The panel portion 20 forms at least a part of the inner wall surface 2 facing the vehicle interior side. In this embodiment, the panel portion 20 forms a lower portion of the inner wall surface 2 located on the side in the vehicle width direction at the rear of the vehicle interior. In other words, the panel portion 20 is provided on the lower portion of the surface of the side wall at the rear of the vehicle interior facing the vehicle interior side. The panel portion 20 also has a recessed portion 23 recessed toward the outside of the vehicle interior on the panel surface 22 on the vehicle interior side, and the support surface 21 is provided on the bottom surface 24 of the recessed portion 23. That is, in this embodiment, the hook portion 10 is integrally formed in the recessed portion 23 of the panel portion 20. The panel portion 20 is attached to a side inner panel 3, which is a vehicle body frame member.

[0012] The side inner panel 3 is disposed between a quarter pillar (C pillar) 4 on a side of the vehicle body and a rear pillar (D pillar) (not shown) in the front-rear direction of the vehicle, and extends in the vertical direction of the vehicle. The quarter pillar 4 is provided on the rear side of a rear door opening 5 on the side of the vehicle body, and extends in the vertical direction of the vehicle. The rear pillar is located at the rear end of the vehicle body. A side outer panel 6 (see FIG. 5) is disposed on the outer side of the side inner panel 3 in the vehicle width direction, and the combination of the side inner panel 3 and the side outer panel 6 forms a quarter panel.

[0013] As shown in FIG. 2, a panel fixing portion 31 for fixing the panel portion 20 of the interior member 1 is formed in the lower portion of the side inner panel 3. A hole portion 31a into which the recessed portion 23 of the panel portion 20 can be inserted is formed in the panel fixing portion 31. A plurality of fixing holes 31b for fixing the panel portion 20 to the side inner panel 3 with clips or the like are formed around the hole portion 31a. A slide rail of a side door and a retractor portion of a seat belt device (not shown) are arranged near the lower portion of the side inner panel 3, and are covered and hidden by the interior member 1 attached to the side inner panel 3 so as not to be exposed to the inside of the vehicle cabin. A window opening may be provided in the upper portion of the side inner panel 3.

[0014] Hereinafter, the specific structures of the hook portion 10 and the panel portion 20 in the interior member 1 of this embodiment will be described in detail with reference to Figs. 3 to 5. Fig. 3 is an enlarged perspective view of the periphery of a recessed portion 23 formed in the panel portion 20 of the interior member 1 as viewed from the inside of the vehicle compartment. Fig. 4 is an enlarged perspective view of the periphery of the hook portion 10 in Fig. 3 as viewed from the inside of the vehicle compartment. Fig. 5 is a cross-sectional view taken along line AA in Fig. 3. Fig. 5 also shows cross sections of the side inner panel 3 and the side outer panel 6 with the interior member 1 attached, together with the cross section of the interior member 1.

[0015] As shown in Figs. 3 to 5, the hook portion 10 has an engagement portion 11 and a plurality of (here, for example, two) support portions 12. The engagement portion 11 is disposed on the vehicle interior side with a gap from the support surface 21 of the panel portion 20. The engagement portion 11 extends in a first direction (for example, the vehicle vertical direction) along the support surface 21. The engagement portion 11 has a central portion in the longitudinal direction located slightly closer to the vehicle interior side than both ends, and is gently inclined from the central portion toward the vehicle exterior side from both ends (see Fig. 5). By making the engagement portion 11 inclined in this way, the tensile load acting on the engagement portion 11 from the luggage holding member is easily distributed to each support portion 12. Both ends in the longitudinal direction of the engagement portion 11 are formed in a substantially arc shape when viewed from the vehicle interior side (see Figs. 3 and 4). The substantially arc-shaped shape here includes a shape with a curvature of a circle or an ellipse, a polygon with multiple vertices arranged in an arc with an interior angle of less than 90°, a sector shape, etc. The corners of the periphery of the engaging portion 11 facing the interior of the vehicle are rounded and chamfered.

[0016] The two support parts 12 extend from both ends of the engagement part 11 in the longitudinal direction toward the outside of the vehicle cabin and are connected to the support surface 21 of the panel part 20. Each support part 12 has a columnar or cylindrical shape. The side wall of each support part 12 is formed so as to expand in the direction along the support surface 21 as it moves toward the outside of the vehicle cabin when viewed from the inside of the vehicle cabin. Specifically, the side wall of each support part 12 in this embodiment is composed of an outer wall part 12a and an inner wall part 12b, and has a semicircular or semielliptical outline shape when viewed from the inside of the vehicle cabin. The outer wall part 12a is provided along the approximately arc-shaped edge of the end of the engagement part 11 in the longitudinal direction, and expands in diameter in the direction along the support surface 21 as it moves toward the outside of the vehicle cabin. The inner wall part 12b connects both ends of the outer wall part 12a in the circumferential direction and extends approximately straight toward the outside of the vehicle cabin. The contour shape of the side wall of each support portion 12 as viewed from inside the vehicle compartment is not limited to a semicircular or semielliptical shape, but may be a sector, circle, ellipse or polygon.

[0017] An insertion portion 13 extending in a second direction (e.g., the vehicle front-rear direction) along the support surface 21 is formed between the engagement portion 11 and the pair of support portions 12 of the hook portion 10 and the support surface 21 of the panel portion 20. The second direction intersects with the longitudinal direction (first direction) of the engagement portion 11. A luggage holding member is inserted into the insertion portion 13 when holding luggage in the vehicle interior.

[0018] Between the inner wall portions 12b of each support portion 12, a pair of reinforcing portions 14 extending in the first direction is provided. The pair of reinforcing portions 14 constitute a part of the engagement portion 11 and have a function and role of engaging with the luggage holding member. The end portion on the interior side of each reinforcing portion 14 is connected to both sides of the surface of the engagement portion 11 on the exterior side of the vehicle interior. The end portion on the exterior side of each reinforcing portion 14 is formed in an arch shape approaching the support surface 21 from the center toward both ends in the first direction. Since each reinforcing portion 14 connects the engagement portion 11 and the inner wall portion 12b of each support portion 12, the tensile load acting on the engagement portion 11 is easily distributed to each support portion 12. In addition, since each reinforcing portion 14 is formed in an arch shape, when the luggage holding member is inserted into the insertion portion 13, the contact area between the luggage holding member and the surface of each reinforcing portion 14 on the exterior side of the vehicle interior can be increased. This makes it possible to avoid local concentration of the tensile load on the luggage holding member and the surface of the reinforcement portion 14 on the exterior side of the vehicle interior.

[0019] As shown in Figs. 3 and 5, the recessed portion 23 of the panel portion 20 has a bottom surface 24 on which the support surface 21 is provided, and a peripheral wall portion 25 that extends from the peripheral portion 21a of the support surface 21 toward the interior of the vehicle and connects to the panel surface 22. The peripheral wall portion 25 is composed of an inner inclined portion 25a located on the inside of the vehicle compartment, an outer inclined portion 25b located on the outside of the vehicle compartment, and a straight portion 25c that connects between the inner inclined portion 25a and the outer inclined portion 25b. The inner inclined portion 25a extends at an incline so as to approach the hook portion 10 as it moves from the panel surface 22 toward the outside of the vehicle compartment. The outer inclined portion 25b extends at an incline so as to move away from the hook portion 10 as it moves toward the inside of the vehicle compartment from the peripheral portion 21a of the support surface 21. The straight portion 25c extends linearly from the end of the outer inclined portion 25b toward the interior of the vehicle compartment and connects to the end of the inner inclined portion 25a on the outside of the vehicle compartment.

[0020] Regarding the positional relationship between the peripheral wall portion 25 of the panel portion 20 and the hook portion 10, the end portion of the hook portion 10 on the vehicle interior side is provided at a position overlapping the end portion of the inner inclined portion 25a on the vehicle exterior side when viewed from a direction parallel to the support surface 21 (see dashed line X1 in FIG. 5). In this embodiment, the vehicle interior side surface of the longitudinal center portion of the engagement portion 11 of the hook portion 10 is arranged to overlap the boundary (dashed line X1) between the inner inclined portion 25a and the straight portion 25c in the peripheral wall portion 25 of the panel portion 20. Also, the expansion amount (diameter expansion amount) in the direction along the support surface 21 of the outer wall portion 12a of each support portion 12 is increased at the bottom portion 12c located on the vehicle exterior side relative to the boundary (dashed line X2 in FIG. 5) between the outer inclined portion 25b and the straight portion 25c when viewed from a direction parallel to the support surface 21. In other words, the outer wall portion 12a of the support portion 12 expands in a direction along the support surface as it moves toward the outside of the vehicle compartment, and connects to the support surface 21 with a more gentle slope at a bottom portion 12c that is close to the support surface 21.

[0021] 4 and 5, the recessed portion 23 of the panel portion 20 has a rib 50 extending from a portion of the support surface 21 adjacent to the hook portion 10 toward the outside of the vehicle compartment. In this embodiment, the rib 50 has a pair of first ribs 51 provided along the outer edge of the vehicle compartment of each of the outer wall portions 12a of the pair of support portions 12, and a plurality of second ribs 52 located between both ends of one first rib 51 and both ends of the other first rib 51 (see FIG. 5). Although not shown, the first rib 51 is disposed so as to be shifted radially outward or radially inward from the outer edge of the outer wall portion 12a of the support portion 12 on the outer side of the vehicle compartment when viewed from the outside of the vehicle compartment.

[0022] Furthermore, as shown in FIG. 3, a plurality of mounting holes 26 for inserting clips or the like are formed around the recessed portion 23 of the panel portion 20, corresponding to the plurality of fixing holes 31b of the side inner panel 3. As shown in FIG. 5, the recessed portion 23 of the panel portion 20 is inserted into the hole portion 31a of the panel fixing portion 31 formed in the side inner panel 3. A space S capable of accommodating the rib 50 is formed between the hole portion 31a of the side inner panel 3 and the side outer panel 6 with the recessed portion 23 of the panel portion 20 inserted therein. In other words, the recess amount of the recessed portion 23 or the length of the rib 50 in the vehicle exterior direction is set so that the distance between the bottom of the recessed portion 23 inserted into the hole portion 31a and the side outer panel 6 is larger than the length of the rib 50 in the vehicle exterior direction. The panel portion 20 with the recessed portion 23 inserted into the hole portion 31a of the side inner panel 3 is fixed with clips or the like by aligning the respective fixing holes 31b of the side inner panel 3 with the respective mounting holes 26 of the panel portion 20.

[0023] In the present embodiment, an example has been shown in which a bottomless hole 31a penetrating the side inner panel 3 is formed as the panel fixing portion 31 of the side inner panel 3, but in addition to this, for example, as shown in Fig. 6, a bottomed hole 31c into which the recessed portion 23 of the panel portion 20 can be inserted may be provided in the side inner panel 3. In the case of the bottomed hole 31c, the depth of the hole 31c is set so as to ensure a space capable of accommodating the rib 50 of the panel portion 20.

[0024] Next, the operation of the vehicle interior member structure according to this embodiment will be described. In the interior member 1 having the above-mentioned structure, the hook portion 10 and the panel portion 20 are integrally molded, so that it is not necessary to provide a cutout portion in the trim member to expose the rope hook separate from the trim member to the interior side of the vehicle as in the conventional structure described above. That is, in the interior member 1 according to the present embodiment, the hook portion 10 that can be engaged with the luggage holding member is integrally molded in a state supported by the support surface 21 of the panel portion 20, so that the hook portion 10 is always exposed to the interior side of the vehicle. Therefore, the members arranged on the exterior side of the interior member 1 (such as the lower portion of the side inner panel 3, the slide rail of the side door, and the retractor portion of the seat belt device) are not visible from the interior side of the vehicle, so that the deterioration of the aesthetic appearance of the interior of the vehicle can be suppressed. In addition, the leakage of road noise and other noise propagated to the exterior side of the interior member 1 into the interior of the vehicle can be suppressed. Furthermore, the integral molding of the hook portion 10 and the panel portion 20 can improve production efficiency.

[0025] In an interior member 1 in which the hook portion 10 and the panel portion 20 are integrally molded, it is important to increase the connection rigidity between the hook portion 10 and the panel portion 20. In this embodiment, a recessed portion 23 recessed toward the outside of the vehicle compartment is formed in the panel surface 22 of the panel portion 20, and a support surface 21 that supports the hook portion 10 inside the vehicle compartment is provided on a bottom surface 24 of the recessed portion 23. In such an interior member 1, when a luggage holding member engaged with the engaging portion 11 of the hook portion 10 is pulled toward the inside of the vehicle compartment, a load (hereinafter referred to as a "tensile load") acting on the engaging portion 11 is transmitted to the supporting surface 21 of the panel portion 20 via the pair of supporting portions 12.

[0026] At this time, since the hook portion 10 is provided in the recessed portion 23 of the panel portion 20, a part of the tensile load transmitted to the support surface 21 is received by the peripheral wall portion 25 of the recessed portion 23. This improves the connection rigidity between the hook portion 10 and the panel portion 20, and prevents the hook portion 10 from jumping out toward the inside of the vehicle cabin due to the tensile load. In addition, since the vibration surface (panel surface 22) of the panel portion 20 is partitioned by providing the recessed portion 23, vibration of the panel portion 20 (particularly surface vibration) can be suppressed. Furthermore, since at least a part of the hook portion 10 is disposed outside the vehicle cabin relative to the panel surface 22 of the panel portion 20 according to the recess amount of the recessed portion 23, it is possible to suppress the protrusion of the hook portion 10 into the vehicle cabin, and interference between the hook portion 10 and other members, such as cargo, disposed in the vehicle cabin can be reduced. In particular, when the hook portion 10 is not in use, i.e., when the luggage holding member is not engaged with the hook portion 10, it becomes easier to arrange other members adjacent to the panel portion 20, and the other members can be arranged efficiently.

[0027] In addition, in the interior member 1 according to this embodiment, the inner inclined portion 25a is provided on the peripheral wall portion 25 of the recessed portion 23. This inner inclined portion 25a prevents the tensile load received by the peripheral wall portion 25 of the recessed portion 23 from concentrating locally at the connection point between the peripheral wall portion 25 and the panel surface 22, and prevents the peripheral wall portion 25 from deforming toward the panel surface 22 starting from the connection point. This effectively prevents the hook portion 10 from protruding toward the inside of the vehicle cabin. Furthermore, in this embodiment, the inner inclined portion 25a is provided at a position where the end portion on the outside of the vehicle cabin and the end portion on the inside of the vehicle cabin of the hook portion 10 overlap when viewed from a direction parallel to the support surface. This causes the entire hook portion 10 to be disposed outside the vehicle cabin relative to the panel surface 22 of the panel portion 20. This makes it possible to eliminate the protrusion of the hook portion 10 into the vehicle cabin, and prevents interference between the hook portion 10 and other members, such as cargo, disposed in the vehicle cabin. In particular, when the hook portion 10 is not in use, i.e., when the luggage holding member is not engaged with the hook portion 10, it becomes possible to place other members adjacent to the panel portion 20, allowing the other members to be positioned more efficiently.

[0028] In the interior member 1 according to the present embodiment, the recessed portion 23 of the panel portion 20 is inserted and fixed in the hole portion 31a formed in the panel fixing portion 31 of the side inner panel 3 (body frame member). As a result, when the tensile load received by the peripheral wall portion 25 of the recessed portion 23 is transmitted to the panel surface 22, a part of the load is received around the hole portion 31a of the side inner panel 3, so that the hook portion 10 can be more effectively prevented from jumping out toward the inside of the vehicle cabin. Furthermore, the hole portion 31a of the side inner panel 3 has a space S that can accommodate the rib 50. Therefore, even if the rib 50 is provided on the outside of the vehicle cabin of the recessed portion 23 of the panel portion 20, the support surface 21 can be positioned on the outside of the vehicle cabin. By providing the rib 50 in the recessed portion 23, when a tensile load acts on the hook portion 10, stress is less likely to concentrate on the connection area between each support portion 12 of the hook portion 10 and the support surface 21. Therefore, the rib 50 suppresses deformation around the connection area caused by a tensile load, while suppressing or eliminating protrusion of the hook portion 10 into the vehicle interior.

[0029] In the interior member 1 according to this embodiment, the engaging portion 11 of the hook portion 10 is supported on the supporting surface 21 by a pair of supporting portions 12, and the side walls (outer wall portions 12a) of each supporting portion 12 are formed so as to expand in a direction along the supporting surface 21 as it moves toward the outside of the vehicle compartment when viewed from inside the vehicle compartment. Such a shape of the side walls increases the connection area between each supporting portion 12 and the supporting surface 21, making it easier to distribute the tensile load acting on each supporting portion 12 from the engaging portion 11 to the supporting surface 21. In particular, if the contour shape of the supporting portion 12 as viewed from inside the vehicle compartment is semicircular or semielliptical, and the outer wall portion 12a corresponding to the curved portion of the contour shape is formed so as to expand in diameter in a direction along the supporting surface 21 as it moves toward the outside of the vehicle compartment, it is possible to avoid local stress concentration on the outer wall portion 12a of the supporting portion 12 and the connection surface between the outer wall portion 12a and the supporting surface 21. Therefore, according to the interior member 1 of the present embodiment, it is possible to realize a structure in which the support portion 12 or the support surface 21 is less likely to deform toward the inside of the vehicle compartment due to a tensile load.

[0030] In addition, in the interior member 1 according to this embodiment, the peripheral wall 25 of the recess 23 is provided with an outer inclined portion 25b. This outer inclined portion 25b makes it difficult for the tensile load transmitted from each support portion 12 of the hook portion 10 to the support surface 21 to concentrate locally at the connection point between the support surface 21 and the peripheral wall 25. Furthermore, the expansion amount (diameter expansion amount) in the direction along the support surface 21 in the side wall (outer wall portion 12a) of the support portion 12 is increased at the bottom portion 12c located outside the vehicle cabin from the boundary between the outer inclined portion 25b and the straight portion 25c when viewed from a direction parallel to the support surface 21. This makes it difficult for the tensile load transmitted from the engagement portion 11 of the hook portion 10 to concentrate locally at the connection point between each support portion 12 and the support surface 21. Therefore, deformation of the support surface 21 or each support portion 12 starting from each connection point due to a tensile load is suppressed, and the hook portion 10 is reliably prevented from jumping out toward the inside of the vehicle compartment.

[0031] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and changes are possible based on the technical concept of the present invention. For example, in the above-described embodiment, an example was shown in which the interior member 1 is provided on the lower part of the inner wall surface 2 located on the side in the vehicle width direction at the rear of the vehicle compartment, but the arrangement of the interior member 1 is not limited to this, and the interior member 1 can be provided on an inner wall surface at any position in the vehicle compartment. To give a specific example, the interior member 1 (hook portion 10 and panel portion 20) may be provided on a surface facing the inside of the vehicle compartment, such as a dash panel at the front of the vehicle compartment, a side door panel at the side of the vehicle, a back door panel at the rear of the vehicle, a roof panel at the upper part of the vehicle compartment, a seat (a side panel or a back panel of a seat back), or a floor panel at the lower part of the vehicle compartment.

[0032] FIG. 7 is a rear view showing a schematic structure of a modified example in which a hook portion 10 and a panel portion 20 are provided on a seat. In this modified example, a panel portion 20 similar to that of the above-described embodiment is applied as a back portion of a seat back 61 of a seat 60, at least a part of which is made of resin. In the panel portion 20 of the modified example, two recessed portions 23 are formed at an interval on the left and right, and a hook portion 10 is provided in each recessed portion 23. The seat back 61 is configured to be rotatable about a rotation shaft 63 with respect to a seat portion 62. In the modified example of FIG. 7, the surface facing the outside of the vehicle compartment in the above-described embodiment corresponds to the inner surface (or the front surface) of the seat back 61.

[0033] In this modified example, the insertion portions corresponding to the hook portions 10 are arranged so that their insertion directions overlap, so that a luggage holding member such as a rope can be engaged with each of the two hook portions 10. Therefore, when luggage is held by the luggage holding member, the luggage holding member can be reliably supported by the two hook portions 10, and luggage can be appropriately held inside the vehicle cabin.

[0034] When the hook portion 10 and the panel portion 20 are provided on the seat 60 as in the above modified example, it is preferable to provide the hook portion 10 and the panel portion 20 on the back of the rear seat, which allows the seat back 61 to be rotated forward. This allows the position of the hook portion 10 to be adjusted between the position where the seat back 61 is upright and the position where the seat back 61 is tilted forward. In other words, since the seat back 61 of the rear seat can be positioned by tilting it forward around the rotation shaft 63, the position of the hook portion 10 can be changed according to the position of the seat back 61. This allows for greater freedom in the method of holding luggage by the luggage holding member.

[0035] In addition, in the embodiment described above, an example has been shown in which both longitudinal ends of the engagement portion 11 are supported by a pair of support portions 12, but the engagement portion may be supported by one or three or more support portions depending on the shape of the engagement portion, etc. [Explanation of symbols]
