[Figure 2] This is a schematic cross-sectional view showing the configuration of an attachment part to be attached to a deck board according to the deck board structure of this embodiment. [Figure 3] The diagram schematically shows the usage state of the deck board according to this embodiment. (A) is a side view showing the first usage state of the deck board, and (B) is a perspective view from the rear of the sheet showing the second usage state of the deck board. [Modes for carrying out the invention]

[0013] Hereinafter, an example of an embodiment of the deck board structure according to the present invention will be described using Figures 1 to 3. As shown in Figure 1, the "deck board 10" to which the deck board structure according to this embodiment is applied is attached to a rear seat 14 for a vehicle (hereinafter referred to as seat 14) mounted on a vehicle 12. The arrows FR, UP, and RH shown as appropriate in each figure indicate the forward, upward, and rightward directions of the seat 14, respectively. In this embodiment, the forward direction of the seat 14 coincides with the forward direction of the vehicle 12, the upward direction of the seat 14 coincides with the upward direction of the vehicle 12, and the rightward direction of the seat 14 coincides with the rightward direction of the vehicle 12.

[0014] The seat 14 comprises a seat back 16, which is the seat body capable of supporting the occupant's back, a seat cushion (not shown) capable of supporting the occupant's buttocks and thighs, and a headrest 20 capable of supporting the occupant's head. The seat back 16 is designed to tilt relative to the seat cushion in the front-to-back direction.

[0015] Furthermore, the "back surface 16A" of the seat back 16 has a bulge 16B that protrudes toward the rear of the seat, and as shown in Figure 3, this bulge 16B has a flat portion 16B1 that extends in the vertical direction and the width direction of the seat. The deck board 10 is attached to the bulge 16B.

[0016] The deck board 10 is formed by blow molding resin to create a rectangular plate shape, and one end 10A of it is attached to the upper sheet portion of the bulge 16B via a pair of mounting parts 22. Each mounting part 22 comprises a fixing piece 22A fixed to the end 10A of the deck board 10, a fixing piece 22B fixed to the bulge 16B, and a ratchet mechanism (not shown) interposed between the fixing pieces 22A and 22B.

[0017] Furthermore, by attaching the deck board 10 to the seat back 16 via the mounting portion 22, the deck board 10 can be positioned at a predetermined angle of rotation relative to the seat back 16.

[0018] In the following, the state in which the deck board 10 is positioned along the back surface 16A (normal state) will be referred to as the first state, and the state in which the deck board 10 is positioned in a rotated state relative to the seat back 16 will be referred to as the second state.

[0019] In this embodiment, a recess 24 is formed on the "surface 10B" located on the rear side of the sheet on the deck board 10 in the first state, as shown in Figure 3(A). This recess 24 is covered with a resin "cap portion 26" that is detachable from the recess 24 in the first state.

[0020] On the other hand, for the second state, more specifically, when the deck board 10 rotates upward with respect to 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 concave portion 24 is attached to the concave portion 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 the 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 concave portion 24. And in a state where the base plate 30 is fitted into the concave portion 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 whose fastening direction is 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 a state where it is exposed.

[0024] On the other hand, the locking ring 34 is in an annular shape when viewed from 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 concave portion 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] <Functions and Effects of the Present Embodiment> Next, the operation and effects of this embodiment will be described.

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

[0028] However, when the deck board 10 is rotated relative to the seat back 16, the deck board 10 is cantilevered at one end 10A, which may make it difficult to support the load acting on the deck board 10.

[0029] In this embodiment, when the deck board 10 is in a first state, positioned along the back surface 16A of the seat back 16, a recess 24 is provided on the surface 10B of the deck board 10 that is located on the rear side of the seat. In the first state, this recess 24 is covered by a cap portion 26 that is detachably attached to the recess 24.

[0030] On the other hand, in the second state, when the deck board 10 is rotated relative to the seat back 16, that is, when the deck board 10 is positioned in an unfolded state relative to the seat back 16, the attachment part 28, which is detachable from the recess 24, can be attached to the recess 24 in place of the cap part 26. The attachment part 28 can then support the deck board 10 relative to the "vehicle body 38" via a component.

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

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

[0033] Furthermore, as shown in Figure 3(B), when the seat back 16 is upright, the deck board 10 can be supported against the pillar portion 38A via the tether belt 44 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. Note that the deck board 10 and seat back 16 can assume various positions other than those shown in Figure 3, and the deck board 10 can be supported against the vehicle body 38 by using the attachment portion 28 as described above in each position.

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