Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the prior art described in Patent Document 1 above, when the deck board is deployed, it is in a cantilever-supported state on the front end side, and there is room for improvement in terms of supporting the load acting on the deck board when the deck board is deployed.

[0005] In consideration of the above facts, an object of the present invention is to obtain a deck board structure capable of supporting the load acting on the deck board when the deck board is deployed.

Means for Solving the Problems

[0006] The deck board structure according to the first aspect includes a deck board having one end rotatably supported with respect to the back surface of the seat body and positionable at a predetermined angle with respect to the seat body, and a concave portion provided on a surface of the deck board located on the rear side of the seat when the deck board is in a first state of being located along the back surface. In the first state, the concave portion is covered with a cap portion detachable from the concave portion, and in a second state where the deck board is positioned in a state of being rotated with respect to the seat body, an attachment portion detachable from the concave portion and capable of supporting the deck board with respect to the vehicle body via a member is attached to the concave portion.

[0007] According to the deck board structure according to the first aspect, one end of the deck board is rotatably supported with respect to the back surface of the seat body, and this deck board is positionable at a predetermined angle with respect to the seat body. Therefore, in this aspect, the deck board can be used for various applications.

[0008] By the way, when the deck board is rotated with respect to the seat body, the deck board is in a state of being cantilever-supported on its one end side, and it is considered that it becomes difficult to support the load acting on the deck board.

The seat back 16 is tiltable in the front-rear direction of the seat with respect to the seat cushion.

[0015] And on the "rear surface 16A" of the seat back 16, a bulging portion 16B bulging toward the rear side of the seat is formed. As shown in FIG. 3, this bulging portion 16B includes a flat portion 16B1 extending in the vertical direction and the width direction of the seat. And a deck board 10 is attached to the bulging portion 16B.

[0016] The deck board 10 is formed in a rectangular plate shape by blow molding resin, and its "one end portion 10A" is attached to the upper portion of the bulging portion 16B on the seat side via a pair of attachment portions 22. This attachment portion 22 includes a fixed piece portion 22A fixed to one end portion 10A of the deck board 10, a fixed piece portion 22B fixed to the bulging portion 16B, and a ratchet mechanism (not shown) interposed between the fixed piece portion 22A and the fixed piece portion 22B.

[0017] And by attaching the deck board 10 to the seat back 16 via the attachment portion 22, the deck board 10 can be positioned in a state of being rotated by a predetermined angle with respect to the seat back 16.

[0018] In the following, the state where the deck board 10 is located along the rear surface 16A (normal state) is referred to as the first state, and the state where the deck board 10 is positioned in a state of being rotated with respect to the seat back 16 is referred to as the second state.

[0019] And in the present embodiment, a "recess 24" is formed on the "surface 10B" located on the rear side of the seat of the deck board 10 in the first state, as shown in FIG. 3(A). This recess 24 is covered with a resin-made "cap portion 26" that is detachable with respect to the recess 24 in the first state.

[0020] On the other hand, in the second state, more specifically, when the deck board 10 rotates upward on the sheet and the surface 10C on the side opposite to the surface 10B is separated from the flat surface portion 16B1 of the bulging portion 16B, an "attachment portion 28" that is detachable with respect to the recess 24 is attached to the recess 24 in place of the cap portion 26.

[0021] As shown in FIG. 2, the attachment portion 28 includes a resin base plate 30 that constitutes a main part thereof, a leg mounting member 32, and a locking ring 34.

[0022] Specifically, the base plate 30 is in a plate shape that can be fitted into the recess 24. And in a state where the base plate 30 is fitted into the recess 24, a leg mounting member 32 is provided on the surface 30A located on the surface 10B side of the deck board 10, and a locking ring 34 is provided on the surface 30B located on the surface 10C side of the deck board 10.

[0023] The leg mounting member 32 is made of metal, and a female screw portion 32A with the fastening direction being the plate thickness direction of the base plate 30 is provided at the central portion thereof, and a part of it is embedded in the base plate 30 in an exposed state.

[0024] On the other hand, the locking ring 34 is in an annular shape when viewed in the sheet width direction, and is rotatably attached around the sheet vertical direction to a ring base 36 made of metal and attached to the surface 30B of the base plate 30 via a mounting member (not shown).

[0025] And the locking ring 34 protrudes to the surface 30B side of the base plate 30 through a slit portion 37 provided continuously with the recess 24 in the deck board 10. That is, in the present embodiment, the attachment state of the attachment portion 28 to the deck board 10 is maintained even when the locking ring 34 is pulled.

[0026] <Actions and Effects of the Present Embodiment> Next, the operations and effects of the present embodiment will be described.

[0027] In the present embodiment, as shown in FIG. 1, one end portion 10A of the deck board 10 is rotatably supported with respect to the back surface 16A of the seat back 16, and this deck board 10 can be positioned at a predetermined angle with respect to the seat back 16. Therefore, in the present embodiment, the deck board 10 can be used for various purposes.

[0028] By the way, in a state where the deck board 10 is rotated with respect to the seat back 16, the deck board 10 is in a state of being cantilever-supported on the one end portion 10A side, and it is considered that it is difficult to support the load acting on the deck board 10.

[0029] Here, in the present embodiment, when the deck board 10 is in the first state of being located along the back surface 16A of the seat back 16, a recess 24 is provided on the surface 10B located on the rear side of the seat in the deck board 10. And in the first state, this recess 24 is covered with a cap portion 26 that is detachable with respect to the recess 24.

[0030] On the other hand, in a state where the deck board 10 is rotated with respect to the seat back 16, that is, in the second state where the deck board 10 is positioned in a state of being deployed with respect to the seat back 16, an attachment portion 28 that is detachable with respect to the recess 24 can be attached to the recess 24 in place of the cap portion 26. And the attachment portion 28 can support the deck board 10 with respect to the "vehicle body 38" via a member.

[0031] For example, as shown in FIG. 3(A), in a state where the deck board 10 is rotated above the seat and the surface 10C is located on the same plane as the flat portion 16B1 of the bulging portion 16B and the seat back 16 is tilted forward of the seat, a leg member 40 is attached to the attachment portion 28.

[0032] This leg member 40 is provided with a male screw portion 40A at its tip end that can be fastened to the female screw portion 32A of the leg mounting member 32. By fastening the male screw portion 40A to the female screw portion 32A, the deck board 10 can be supported via the leg member 40 against a floor portion (not shown) of the vehicle body 38.

[0033] Also, as shown in FIG. 3(B), when the seat back 16 is in the upright state, by connecting the locking ring 34 and the locking portion 42 provided on the pillar portion 38A of the vehicle body 38 with the tether belt 44, the deck board 10 can be supported against the pillar portion 38A via the tether belt 44. Note that the deck board 10 and the seat back 16 can take various postures other than the posture shown in FIG. 3, and by using the attachment portion 28 as described above in each posture, the deck board 10 can be supported against the vehicle body 38.

[0034] Therefore, in the present embodiment, when the deck board 10 is deployed, the load acting on the deck board 10 can be supported.
