[0003] [Patent Document 1] Patent No. 4111178 [Patent Document 2] Patent No. 5209995 [Patent Document 3] JP 2015-166231 A Summary of the Invention [Problem to be solved by the invention]

[0004] In vehicles in which the seat backs of the seats arranged at the front of the luggage compartment can be folded forward to make the backs approximately horizontal, the floor surface of the luggage compartment may be formed at a height lower than the backs of the folded seat backs in order to ensure the capacity of the luggage compartment. However, some users may consider it important to have a large flat space, as in the vehicle described in Patent Document 3.

[0005] The present invention has been made in consideration of such circumstances, and has an objective of providing a vehicle luggage compartment structure capable of forming a flat space in a vehicle with a large luggage compartment, and also an objective of providing a second deck construction set for a vehicle for forming such a vehicle luggage compartment structure. [Means for solving the problem]

[0006] In order to solve the above problems, the vehicle luggage compartment structure of the present invention comprises: A first deck board is provided behind a seat back that can be folded forward until the back surface of the seat back is substantially horizontal, and is installed at a height lower than the back surface of the folded-down seat back; A second deck board that can be installed at the same height as the back surface of the seat back when folded forward in a position overlapping the upper part of the first deck board; The present invention is characterized by comprising:

[0007] In this vehicle luggage compartment structure, even in a vehicle in which the upper surface of the first deck board is lower than the back surface of the seat back, by installing the second deck board, a relatively large flat space can be formed in the vehicle cabin by the seat back and the second deck board, improving the flexibility of use of the vehicle cabin. Also, in this vehicle luggage compartment structure, by installing two deck boards, the luggage compartment can be roughly divided into two levels, improving the flexibility of storage.

[0008] In the above configuration, the first deck board can be configured to be contained inside the second deck board in the vehicle width direction in a top view.

[0009] With this vehicle luggage space structure, the first deck board can be raised or removed from an opening formed when the second deck board is raised or removed starting from the front side, making it possible to effectively use the space below the first deck board.

[0010] In the above configuration, the vehicle can be configured to include a front support that is held against left and right side wall portions in the vehicle cabin in a position extending in the vehicle width direction and supports a front side of the second deck board, a rear support that is arranged behind the front support in a position extending in the vehicle width direction and supports a rear side of the second deck board, and a pair of retaining members that are installed on a floor surface facing upwardly on each of the left and right sides of the first deck board and hold both ends of the rear support.

[0011] This vehicle luggage compartment structure embodies a configuration for supporting the second deck board, and can easily construct a second deck that is connected to the seat back and flat with the seat back. Also, because no member for supporting the second deck board is installed on top of the first deck board, lifting the second deck board also makes it possible to lift and remove the first deck board, making it possible to effectively utilize the space below the first deck board.

[0012] In the above configuration, the vehicle luggage compartment structure can be configured such that each of the left and right side wall portions has a bulge portion that bulges into the passenger compartment so as to cover a wheel house of the vehicle, the front support body is disposed between the bulge portions of the left and right side wall portions, and each of the pair of retaining members fills the left and right spaces of the second deck board rearward of the bulge portion and has an upper surface that is flush with an upper surface of the second deck board.

[0013] In this vehicle luggage compartment structure, the upper surfaces of the pair of retaining members are also flush with the upper surface of the second deck board, expanding the flat space and making it possible to effectively utilize the space above the second deck.

[0014] In the above configuration, a front support body may be provided that is held against left and right side wall portions inside the vehicle cabin in a position extending in the vehicle width direction and supports the front side of the second deck board, and the front support body may have a self-supporting support structure for supporting the rear side of the second deck board in an upright position in which it is raised.

[0015] With this vehicle luggage space structure, the second deck board can be raised without the need for a person to support it, making it easy to load and unload luggage into the space below the second deck board.

[0016] In the above configuration, the second deck board has a shape in which a dimension in the vehicle width direction decreases toward the front of the front end portion, and each of the left and right sides of the front end portion is an inclined portion, the front support body includes a longitudinal front support member on which the second deck board is placed, and a pair of front brackets fixed to both ends of the front support member and for attachment to the left and right side wall portions, Each of the pair of front brackets has a fitting groove that opens upward and into which the inclined portion of the second deck board fits, The free-standing support structure can be configured to support the second deck board in the upright position by inserting the front end of the second deck board below the front support member and fitting each of the inclined portions into the fitting grooves of the pair of front brackets.

[0017] The vehicle luggage compartment structure configured as described above embodies a structure that supports the second deck board in an upright position, and is capable of supporting the second deck board in an upright position with a simple structure.

[0018] In the above configuration, the vehicle may include a rear support body that is arranged in a position extending in the vehicle width direction and supports the rear side of the second deck board, and a pair of retaining members that are located on each of the left and right sides of the first deck board and installed on a floor surface facing upward and hold both ends of the rear support body, and the pair of retaining members may be configured to have tonneau cover receiving portions that engage both ends of a roll-up tonneau cover mounted on the vehicle.

[0019] With this vehicle luggage space structure, the tonneau cover, which cannot be stored within the first deck board, can be stored between the first and second deck boards, making it possible to effectively utilize the space formed on the second deck board together with the seat backs.

[0020] In the above-mentioned configuration, the tonneau cover storage portion may be formed in a groove shape that opens to the interior side of the vehicle compartment and extends in the vertical direction with the same width.

[0021] Many tonneau covers have both ends that can be attached by being pushed outward by elastic members, and this vehicle luggage compartment structure allows the tonneau cover to be stored at a different height. In other words, even if luggage is placed in the luggage compartment, the tonneau cover can be stored above the luggage. Depending on the vehicle specifications, even if the deck side trim that forms the side walls of the luggage compartment is made of the same material, the height of the first deck board may differ due to differences in the material that forms the floor, that is, the height of the first deck board may differ relative to the deck side trim. Even in such cases, the vehicle luggage compartment structure allows the tonneau cover to be stored.

[0022] In the above configuration, the vehicle is provided with a rear support body that is disposed in a position extending in the vehicle width direction and supports a rear side of the second deck board, and a pair of holding members that are located on each of the left and right sides of the first deck board and installed on a floor surface that faces upward and hold both ends of the rear support body, The rear support body can be configured to include a longitudinal rear support member on which the second deck board is placed, and a pair of rear brackets fixed to both ends of the rear support member for engaging with each of the pair of retaining members, and can be configured to be detachable from the pair of retaining members.

[0023] With this vehicle luggage compartment structure, not only the second deck board but also the rear support body can be removed, making it easy to open and close the first deck board and to load and unload luggage into the storage space below the first deck board.

[0024] In the above configuration, the vehicle luggage compartment structure includes a rear partition member that is erected at the rear of the luggage compartment to separate the rear end of the luggage compartment, the rear partition member having an upper end that is at a lower height than the second deck board, and each of the pair of rear side brackets has an abutment portion that extends upward from the rear partition member and abuts the rear partition member from above.

[0025] In a vehicle luggage compartment structure configured as described above, even if a large force is applied to the rear portion of the second deck board, the second deck board is also supported by the rear partition member via the rear support, so even if the rear support is detachable, the second deck board can be firmly supported.

[0026] In the above configuration, each of the pair of retaining members can be configured so that an upper surface thereof is flush with an upper surface of the second deck board, and each of the pair of rear brackets can be configured so that an upper surface thereof is flush with an upper surface of the pair of retaining members.

[0027] In the vehicle luggage compartment structure configured as above, the seat backs, the second deck board, the pair of retaining members and the pair of rear side brackets are designed to be flat, ensuring a large flat space.

[0028] In the above configuration, a rear support body is provided that is disposed in a position extending in the vehicle width direction and supports a rear side of the second deck board in a placed state, the second deck board has a rear end formed as a curved portion that bulges rearward, and is supported by the rear support with the curved portion protruding rearward from the rear support, The rear support body may be provided with a curved portion support portion at a center in a vehicle width direction, the curved portion support portion extending rearward to support the curved portion of the second deck board.

[0029] The luggage compartment is often accessed from the rear of the vehicle, and the rear end of the second deck board is prone to being subjected to force from above. With this vehicle luggage compartment structure, the design of the second deck board is ensured while the force applied to the rear end of the second deck board can be adequately supported.

[0030] In order to solve the above problems, the second deck construction set for a vehicle of the present invention comprises: A second deck construction set for a vehicle is provided for a luggage compartment of a vehicle, the first deck being mainly composed of a first deck board that is provided behind a seat back that can be folded forward until the back of the seat back is substantially horizontal and is installed at a height lower than the back of the seat back when folded forward, the second deck construction set being for constructing a second deck above the first deck at the same height as the back of the seat back when folded forward, A second deck board; a front support body that is held against left and right side wall portions in a vehicle interior in a position extending in the vehicle width direction and supports a front side of the second deck board; a rear support disposed behind the front support and extending in the vehicle width direction, the rear support supporting a rear side of the second deck board; a pair of holding members that are located on the left and right sides of the first deck board and that are installed on an upwardly facing floor surface and that hold both ends of the rear support; The present invention is characterized in that it comprises:

[0031] This configuration of second deck construction set for a vehicle makes it easy to construct a second deck that is flat with the back of the seat back for a vehicle having a luggage compartment where the height of the first deck is lower than the back of the seat back when folded forward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] Hereinafter, as a mode for carrying out the present invention, examples of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following examples, and can be carried out in various forms with various modifications and improvements based on the knowledge of those skilled in the art.

[0035] A vehicle employing a vehicle luggage compartment structure according to an embodiment of the present invention is shown in Figs. 1 to 5. Figs. 2, 4, and 5 are views showing the luggage compartment and surroundings of the vehicle 10 from a diagonally rearward perspective. In Figs. 2 to 5, a back door provided at the rear side of the luggage compartment that can be opened and closed, and a deck side trim constituting the left side wall of the luggage compartment are also omitted, and only a deck side trim 12 constituting the right side wall of the luggage compartment, a finish plate (rear partition member) 13 forming the rear end of the luggage compartment, and a trunk box 14 installed on the bottom side of the luggage compartment are shown as interior materials for constituting the luggage compartment of the vehicle 10. The vehicle 10 is a vehicle having a second seat 16, and the second seat 16 is configured so that the seat back 17 can be folded forward to place the back surface 17a of the seat back 17 in a substantially horizontal state. In other words, the vehicle 10 is capable of allowing the space behind the driver's seat and the passenger seat, including the space above the second seat 16, to function as a luggage compartment.

[0036] The vehicle luggage compartment structure of this embodiment includes a generally rectangular first deck board 18 that can be placed on the top of a trunk box 14 having a plurality of storage spaces, as shown in Fig. 5. In the specifications shown in Fig. 5, the vehicle 10 is configured such that an upper surface 18a of the first deck board 18 is placed at a position lower than the height of the back surface 17a of the seat back 17 of the second seat 16, as also shown in Fig. 3, in order to ensure a spacious luggage compartment.

[0037] On the other hand, there is also a demand for a large flat space inside the vehicle cabin. In order to meet such demands, the vehicle 10 is capable of being fitted with a second vehicle deck construction set 20 according to an embodiment of the present invention, and the vehicle luggage compartment structure according to the embodiment of the present invention is realized by installing the second vehicle deck construction set 20. That is, in addition to the first deck on the first deck board 18 shown in Fig. 5, the vehicle 10 is capable of being fitted with a second deck using the second vehicle deck construction set 20 as shown in Figs. 1 to 4. The second vehicle deck construction set 20 will be described in detail below.

[0038] This second deck construction set 20 for a vehicle (hereinafter may be simply referred to as the "deck construction set 20") is comprised of a second deck board 22, a front support 24 that supports the front side of the second deck board 22, a rear support 26 that supports the rear side of the second deck board 22, and a pair of side boards (holding members) 28 that hold the rear support 26. This deck construction set 20 constructs the second deck by installing the pair of side boards 28, the front support 24, the rear support 26, and the second deck board 22 in this order. Below, the features and functions of each component will be described in detail in that order.

[0039] First, the pair of side boards 28 are placed on the deck side trim 12. More specifically, as shown in Fig. 5, each of the left and right deck side trims 12 has not only a side wall portion 12a of the luggage compartment, but also a floor surface 12b that is flush with the upper surface 18a of the first deck board 18 on each of the left and right sides of the first deck board 18, and the side boards 28 are placed on the floor surfaces 12b. Note that the side wall portion 12a of the deck side trim 12 has a bulging portion 12c that bulges into the passenger compartment so as to cover the wheel house of the vehicle 10, and a space that extends in the vehicle width direction is present behind the bulging portion 12c, and the floor surface 12a forms the floor surface of that space. The sideboard 28 is a member that raises the floor surface, and as shown in Figures 1 to 4, 6 and 7, the outer shape of the upper surface 30 facing the outside of the passenger compartment is formed to follow the inner shape of the deck side trim 12, and is placed in contact with the deck side trim 12 with no gaps between them.

[0040] Further, the sideboard 28 is placed so that the outer edge 32 on the interior side of the bottom surface is located outside the vehicle compartment relative to the outer edge on the interior side of the floor surface 12b, and does not protrude from the floor surface 12b of the deck side trim 12. On the other hand, the outer edge 30a on the interior side of the top surface 30 protrudes toward the vehicle compartment relative to the outer edge 32 on the interior side of the bottom surface, and is located at approximately the same position (slightly outward) as the outer edge on the interior side of the floor surface 12b of the deck side trim 12 in the vehicle width direction, as shown in Fig. 7. When the second deck board 22 is placed, as shown in Figs. 1 and 3, the outer edge 30a on the interior side of the top surface 30 abuts against the outer edge of the second deck board 22 in the vehicle width direction, preventing the second deck board 22 from shifting in the vehicle width direction.

[0041] 6 and 8, sideboard 28 has a shape in which wall surface portion 34 on the interior side of the vehicle compartment is hollowed out between multiple pillars 34a from the interior side of the vehicle compartment, thereby expanding the space above first deck board 18 in the vehicle width direction. Also, as shown in Fig. 8, the back surface of sideboard 28 has multiple ribs 36 formed by utilizing the hollowed-out shape, thereby ensuring sufficient rigidity.

[0042] Next, the front side support 24 will be described. As shown in Fig. 9 to Fig. 11, the front side support 24 includes a longitudinal front reinforcement (front side support member) 40 extending in the vehicle width direction, and a pair of front brackets (front side brackets) 42 fixed to both ends of the front reinforcement 40. As shown in Fig. 11, the pair of front brackets 42 includes a metal bracket main body 44 and a resin bracket cover 45 that covers the bracket main body 44. The pair of front brackets 42 are attached to the left and right deck side trims 12, respectively. Specifically, as shown in Fig. 5, the bulging portion 12c is provided with an attachment portion 12d for attaching a hook for hanging luggage in the luggage compartment, and the front bracket 42 is fixed to the deck side trim 12 by utilizing the attachment portion 12d. More specifically, the bracket body 44 of each of the left and right front brackets 42 is fastened to the mounting portion 12d with a bolt 46, and the front reinforcement 40 is placed on top of the bracket bodies 44 and fixed with a bolt and nut 47. Then, a bracket cover 45 is placed so as to cover the end of the front reinforcement 40 and the bracket body 44 from above, and is fixed with a clip 48.

[0043] The bracket cover 45 has a claw portion that protrudes downward from the rearward extending portion, and the claw portion is structured to fit into a fitting hole 28a formed in the sideboard 28. With such a structure, the front support 24 fixes the front end of the sideboard 28 that is simply placed on the floor surface 12b.

[0044] The front support 24 is fixed to the deck side trim 12 with the above-mentioned structure, and can firmly support the second deck board 22 placed thereon. As shown in Figs. 9 to 11, the bracket cover 45 has a shape including a standing wall portion 45a extending in the front-rear direction along the outer edge of the vehicle exterior, and a triangular protruding portion 45b in a plan view. On the other hand, as shown in Fig. 1 and other figures, the second deck board 22 has a shape in which the dimension in the vehicle width direction decreases toward the front of the front end, and each of the left and right ends of the front end forms an inclined portion 22a inclined relative to the front-rear direction. As a result, when the second deck board 22 is placed on the front support 24, as shown in Fig. 12, the inclined portion 22a comes into contact with the protruding portion of the bracket cover 45, and the outer edge in the vehicle width direction of the second deck board 22 continuing from the inclined portion 22a comes into contact with the standing wall portion 45a. Therefore, front support bodies 24 can support second deck board 22 placed on it in a state that prevents it from shifting forward and in the vehicle width direction. The height of protrusion 45b is approximately equal to the thickness of second deck board 22, and the upper surface of second deck board 22 and the upper surface of protrusion 45b are flush with each other.

[0045] Moreover, as shown in Figs. 4 and 13, the front support 24 can support the second deck board 22 in a raised state, more specifically, in an upright position in which the rear side of the second deck board 22 is lifted. In other words, the front support 24 can be considered to have a self-supporting structure. The self-supporting structure utilizes the shape of the front end of the second deck board 22, which narrows toward the front, as described above. In more detail, as shown in Figs. 9 to 11, the bracket cover 45 is formed with a fitting groove 45c that extends generally in the vehicle width direction and opens upward and toward the interior of the vehicle. The fitting groove 45c has a bottom surface that is inclined downward toward the inside of the vehicle compartment, and is inclined toward the front as it approaches the bottom in the depth direction. In other words, by inserting the front end of the second deck board 22 downward and forward into the fitting groove 45c, the inclined portion 22a of the second deck board 22 comes into contact with the bottom surface of the fitting groove 45c. In this state, the front end of second deck board 22, where the width is reduced, fits under front reinforcement 40. Then, when the user releases second deck board 22, as shown in Figure 14, the upper surface of second deck board 22 abuts against front reinforcement 40 and the lower surface abuts against the surface of fitting groove 45c on the rear side of the vehicle, so that second deck board 22 is supported in an upright position.

[0046] Next, the rear support 26 will be described. As shown in Figs. 15 and 16, the rear support 26 is configured to include a longitudinal rear reinforcement (rear support member) 50 extending in the vehicle width direction, and a pair of rear brackets (rear brackets) 52 fixed to both ends of the rear reinforcement 50. The rear support 26 can be placed on the pair of side boards 28 shown in Figs. 6 and 7 such that each of the pair of rear brackets 52 fits into a recess 28b formed on the rear side of each of the pair of side boards 28. When the rear support 26 is placed on the pair of side boards 28, the upper surface of the rear bracket 52 is flush with the upper surface 30 of the side board 28. On the other hand, the rear reinforcement 50 is fixed to the rear bracket 52 at a position where the upper surface is lower than the upper surface of the rear bracket 52 by the thickness of the second deck board 22. In other words, when second deck board 22 is placed, the upper surface of second deck board 22 is flush with the upper surface of rear bracket 52 and upper surface 30 of sideboard 28, forming a flat space over almost the entire interior of the luggage compartment, as shown in Figures 2 and 3. Note that rear bracket 52 is configured to simply be placed in recess 28b of sideboard 28, and rear support body 26 can be easily attached and detached, as shown in Figure 17.

[0047] As shown in Figs. 1 and 2, the second deck board 22 has a curved portion 22b whose rear end bulges rearward in accordance with the shape of the finish plate 13. On the other hand, because the rear reinforcement 50 is linear, the curved portion 22b on the rear end side of the second deck board 22 protrudes rearward from the rear reinforcement 50. Therefore, when a force is applied to the curved portion 22b from above, the second deck board 22 that is simply placed on top may be raised with the front side thereof lifted up with the rear reinforcement 50 as a fulcrum as the curved portion lowers, and may come off. In contrast, in this embodiment, as shown in Figs. 1 and 15 to 17, the rear reinforcement 50 is provided with a striker (curved portion support portion) 54 that protrudes rearward in the center in the vehicle width direction, and is able to resist a force applied from above to the curved portion 22b, thereby preventing the second deck board 22 from rattling. Incidentally, second deck board 22 has a bilaterally symmetrical shape and can be placed upside down. The back side remains the base material of the resin material, while the front side has carpet material attached.

[0048] Furthermore, in this embodiment, rear support body 26 is structured to be able to firmly support a force applied from above to the rear portion of second deck board 22. Specifically, as shown in Figures 15 and 16, rear bracket 52 has protruding portion 52a that protrudes toward the rear, and when rear support body 26 is placed on sideboard 28, protruding portion 52a extends to a position where it overlaps finish plate 13 in the vertical direction, and functions as an abutment portion that abuts finish plate 13 from above. Therefore, the upward force applied to second deck board 22 is distributed to sideboard 28 and finish plate 13 via rear support body 26, and according to the vehicle luggage compartment structure of this embodiment, second deck board 22 can be firmly supported.

[0049] As described above, by installing the deck construction set 20 of this embodiment, a luggage compartment structure in which the second deck board 22 is installed at the same height as the back surface 17a of the seat back 17 above the first deck board 18 provided at a position lower than the back surface 17a of the forward-folded seat back 17, that is, the vehicle luggage compartment structure of the present invention, is realized, and a relatively large flat space can be formed in the vehicle cabin by the second deck mainly composed of the second deck board 22 and above the back surface 17a of the seat back 17. Note that the deck construction set 20 of this embodiment is capable of constructing the second deck without performing any processing on the original vehicle luggage compartment structure shown in FIG. 5. Furthermore, the vehicle luggage compartment structure of this embodiment has not only a storage space under the first deck board 18 but also a storage space formed between the first deck board 18 and the second deck board 22, in other words, the storage space is divided into two levels, and the degree of freedom of storage is high.

[0050] Next, other functions of the vehicle luggage compartment structure of this embodiment realized by the second deck construction set 20 for the vehicle will be described. As described above, in this vehicle luggage compartment structure, none of the components of the second deck construction set 20 is placed on the first deck board 18. Also, as shown in Figs. 7 and 17, the dimension of the first deck board 18 in the vehicle width direction is slightly smaller than the distance between the pair of side boards 28. In other words, the first deck board 18 has approximately the same dimension in the vehicle width direction as the second deck board 22, and is structured to be accommodated inside the second deck board 22 in the vehicle width direction in a top view. And, since the rear support 26 can be easily attached and detached, by removing the rear support 26, it is possible to raise the first deck board 18 from its front end as a starting point or to remove it, as shown in Figs. 18 and 19. Therefore, even if second deck board 22 is located above first deck board 18, the storage space below first deck board 18 can be effectively utilized.

[0051] The vehicle 10 in this embodiment is also provided with a tonneau cover device 60 for covering the upper part of the luggage compartment. The tonneau cover device 60 is a retractable tonneau cover device that includes a flexible sheet-like tonneau cover body 62 and a retracting part 64 consisting of an axle for retracting the tonneau cover body 62 and a case for accommodating the axle. Although the tonneau cover device 60 is not shown in use, FIG. 3 and other figures show an attachment recess 66 for attaching the retracting part 64 of the tonneau cover device 60 and an engagement groove 68 for engaging the rear end of the pulled-out tonneau cover body 62. There is no space provided under the first deck board 18 for storing the tonneau cover device 60. In this vehicle luggage compartment structure, the second deck construction set 20 for a vehicle is capable of accommodating the tonneau cover device 60.

[0052] Specifically, as shown in Figs. 20 to 22, a tonneau cover storage section 70 that stores both ends of the tonneau cover device 60 is provided in each of the pair of sideboards 28. As shown in Figs. 21 and 22, the tonneau cover storage section 70 is formed in a groove shape that opens to the inside of the vehicle compartment and extends in the vertical direction. The upper part of the tonneau cover storage section 70 is continuous with the recess 28b and opens upward. The lower part of the tonneau cover storage section 70 extends to almost the lower end of the sideboard 28. Each of the both ends of the winding section 64 is biased outward in the longitudinal direction by an elastic member, and the tonneau cover device 60 can be held in a state of being stretched in the longitudinal direction. Therefore, the tonneau cover device 60 is inserted from above into the tonneau cover storage section 70 of each of the pair of sideboards 28 in a state of extending in the vehicle width direction, and can be stored in a state in which each of the both ends is biased outward, and can be stored at any height position in the vertical direction. In other words, not only can the tonneau cover device 60 be stored in a state in which it is placed on the first deck board 18 as shown in FIG. 22, but it can also be stored above luggage 72 when the luggage 72 is stored on the first deck board 18 as shown in FIG. 23.

[0053] In addition, in the vehicle 10 of this embodiment, the height at which the first deck board 18 is installed relative to the deck side trim 12 varies depending on the vehicle specifications, resulting in the height positions shown in Figures 24 and 25. As described above, the second deck construction set 20 for a vehicle is installed relative to a pair of deck side trims 12, so it can be installed in the same way even if there are differences in specifications as described above. And, because the tonneau cover storage section 70 is formed in a groove shape extending in the vertical direction, the tonneau cover device 60 can be stored in any specification, as shown in Figures 24 and 25.
