Summary of the Invention

Problems to be Solved by the Invention

[0004] [[ID=XX]]By the way, in the configuration described in Patent Document 1 above, the plate is cantilever-supported by the seat back. Therefore, there is room for improvement from the viewpoint of supporting heavier loads by the plate. Further, in a vehicle seat having an in-vehicle bed board corresponding to the plate, it is required to support a passenger on the in-vehicle bed board. That is, it is required that the in-vehicle bed board can cope with high loads.

[0005] In consideration of the above facts, an object of the present invention is to obtain a vehicle seat provided with an in-vehicle bed board that can cope with high loads.

Means for Solving the Problems

[0006] The first embodiment of a vehicle seat comprises a seat cushion that supports the buttocks of a seated occupant from below, a seat back that is reclined in the front-rear direction relative to the seat cushion and supports the back of the seated occupant from the rear, and a sleeping board that is supported on the back side of the seat back so as to be rotatable in the left-right direction as an axial direction and is extendable in the direction opposite to the axis of rotation, the sleeping board being provided with a front seat support portion that is supported by the seat back of the front seat when the seat back is tilted toward the seat cushion and the sleeping board is extended toward the front.

[0007] In the first embodiment of the vehicle seat, for example, after tilting the seat back toward the seat cushion, the car camping board is rotated forward. Next, the car camping board is extended forward so that the front seat support portion of the car camping board is supported by the seat back of the front seat. This allows the area from the back of the seat back to the car camping board to be used as a space for sleeping in the car or as a cargo area. Here, the car camping board is supported by the seat back of the vehicle seat of the first embodiment and the seat back of the front seat. This configuration can handle heavier loads compared to a configuration in which the car camping board is cantilevered only by the seat back of the vehicle seat of the first embodiment.

[0008] In the second embodiment of the vehicle seat, the front seat support portion is a hook-locking portion that is locked from above to a hook provided on the seat back of the front seat, in the vehicle seat of the first embodiment.

[0009] In the second embodiment of the vehicle seat, when it is not necessary to fasten the hook fastening portion of the car camping board to the hook provided on the seat back of the front seat, the hook provided on the seat back of the front seat can be used as a hook for hanging luggage.

[0010] The third embodiment of the vehicle seat is a vehicle seat of the second embodiment, wherein the overnight sleeping board is configured such that the hook locking portion can be locked to a vehicle-side support portion supported on the vehicle body side when the seat back is positioned to support the back of the seated occupant and the overnight sleeping board is extended toward the rear.

[0011] In the third embodiment of the vehicle seat, for example, with the seat back positioned to support the back of the seated occupant, the sleeping board is extended towards the rear, and the hook-fastening portion of the sleeping board is supported by the vehicle body support portion. This allows the space behind the seat back to be covered from above by the sleeping board. In this way, the sleeping board can function as a tonneau cover in the third embodiment of the vehicle seat. [Effects of the Invention]

[0012] The vehicle seat according to the present invention has the excellent effect of being able to form a cargo compartment that can support heavier loads. [Brief explanation of the drawing]

[0014] A vehicle seat 10 according to an embodiment of the present invention will be described with reference to Figures 1 to 6. In the figures, arrow FR indicates the front side of the vehicle seat 10, arrow UP indicates the upper side of the seat, arrow RH indicates the right side in the seat width direction, and arrow LH indicates the left side in the seat width direction. The front and rear in the seat front-rear direction, the up and down in the seat up and down in the seat up and down in the seat width direction correspond to the front and rear in the vehicle front-rear direction, the up and down in the vehicle up and down in the vehicle up and down in the vehicle width direction, respectively. Furthermore, in the following description, unless otherwise specified, when the directions front, rear, up and down, and left and right are indicated, they refer to the front and rear in the seat (vehicle) front-rear direction, the up and down in the seat (vehicle) up and down direction, and the left and right in the seat (vehicle) width direction.

[0015] As shown in Figure 1, the vehicle seat 10 in this embodiment constitutes the rear seat of the vehicle 12. A vehicle seat 14, which constitutes the front seat of the vehicle 12, is provided in front of the vehicle seat 10.

[0016] The vehicle seat 10 includes a seat cushion 16 that supports the seated occupant's buttocks from below, a seat back 18 that supports the seated occupant's back from the rear, and a sleeping board 20 provided on the seat back 18. As shown in Figures 1 and 2, the seat back 18 is reclined in the front-rear direction relative to the seat cushion 16. As shown in Figure 2, when the seat back 18 is reclined to its furthest point forward, the back surface 22 of the seat back 18 and the rear cargo area bottom surface 24 of the seat back 18 are substantially flush.

[0017] As shown in FIGS. 1 to 3, the in-vehicle parking board 20 is configured to include a first board 26 and a second board 28 that is provided slidably along the first board 26. The arrow S shown in FIG. 2 indicates one side in the direction in which the second board 28 slides along the first board 26. In the following description, the direction of the arrow S will be referred to as one side of the sliding direction, and the direction opposite to the direction of the arrow S will be referred to as the other side of the sliding direction.

[0018] As shown in FIG. 3, the first board 26 includes a first board body 30 formed in a rectangular plate shape and a pair of left and right side wall portions 32 extending from both end portions in the left-right direction of the first board body 30 toward one side in the thickness direction of the first board body 30. The first board 26 also includes a pair of left and right opposing wall portions 34 extending from the end portions of the pair of left and right side wall portions 32 on the side opposite to the first board body 30 in a direction approaching each other. The pair of left and right opposing wall portions 34 and the first board body 30 are arranged at intervals in their respective thickness directions and facing each other in their respective thickness directions. As shown in FIGS. 1 and 2, the end portion on the other side of the sliding direction of the first board 26 described above is supported rotatably about the left-right direction as the axial direction on the back surface 22 side of the seat back 18. In each figure, the rotation axis of the first board 26 is indicated by reference numeral 36.

[0019] As shown in FIG. 3, the second board 28 is formed in a rectangular plate shape. This second board 28 is arranged along the first board body 30 of the first board 26. Also, both end portions in the left-right direction of the second board 28 are arranged in the space formed between the first board body 30, the side wall portions 32, and the opposing wall portions 34 of the first board 26. Thereby, the second board 28 is supported by the first board 26 in a state where it can slide in one side and the other side of the sliding direction along the first board 26. Here, as shown in FIG. 1, the state where the second board 28 does not protrude toward one side in the sliding direction with respect to the first board and the first board 26 and the second board 28 are arranged along the back surface 22 of the seat back 18 will be referred to as the "stored state of the in-vehicle parking board 20".

[0020] As shown in FIGS. 1 and 2, the vehicle seat 14 constituting the front seat includes a seat cushion 38 that supports the buttocks of the seated occupant from below, and a seat back 40 that supports the back of the seated occupant from behind.

[0021] In the vehicle seat 10 described above, after tilting the seat back 18 from the position shown in Figure 1 to the position shown in Figure 2, the overnight sleeping board 20 is rotated forward around the pivot axis 36 from its stored position. At this time, the overnight sleeping board 20 does not come into contact with the seat back 40, regardless of the position of the vehicle seat 14 that constitutes the front seat. In other words, the problem of the overnight sleeping board 20 getting caught on the seat back 40 depending on the position of the vehicle seat 14 that constitutes the front seat is eliminated. Next, the overnight sleeping board 20 is extended forward by sliding the second board 28 along the first board 26 to one side in the sliding direction. Next, the end of the second board 28 on one side in the sliding direction is supported by the seat back 18 of the front seat. Here, as shown in Figures 4 to 6, the end of the second board 28 on one side in the sliding direction is provided with a pair of left and right hook locking parts 42 that serve as front seat support parts, formed in a cylindrical shape with the left-right direction as the axial direction. The pair of left and right hook locking parts 42 are locked from above to a pair of left and right hooks 44 fixed to the seat back 40 of the front seat, spaced apart in the left-right direction, thereby supporting one end of the second board 28 in the sliding direction on the seat back 40 of the front seat. This allows the area from the back of the seat back 18 to the car camping board 20 to be used as a space for sleeping in the car or as a cargo area. Here, the car camping board 20 is supported by the seat back 18 of the vehicle seat 10 and the seat back 40 of the vehicle seat 14. This configuration can withstand heavier loads compared to a configuration in which the car camping board 20 is cantilevered only by the seat back 18 of the vehicle seat 10. Furthermore, in a configuration where the car camping board 20 is cantilevered only to the seat back 18 of the vehicle seat 10, it may be necessary to increase the thickness of the car camping board 20 or take other measures to suppress the bending of the front end of the car camping board 20. However, in this embodiment, such measures are unnecessary, and an increase in the weight of the car camping board 20 can be suppressed.

[0022] Furthermore, as shown in Figures 1 and 4, when it is not necessary to fasten the hook locking portion 42 of the car camping board 20 to the hook 44 provided on the seat back 40 of the vehicle seat 14, the hook 44 provided on the seat back 40 of the vehicle seat 14 can be used as a hook for hanging luggage. In addition, with this configuration, it is possible to provide a fixing point where the hook locking portion 42 is fixed without affecting the design of the vehicle seat 14 that constitutes the front seat.

[0023] Furthermore, as shown in Figure 7, with the seat back 18 positioned to support the back of the seated occupant, the car camping board 20 is rotated upward around the pivot axis 36 from its stored position. Next, the second board 28 is slid along the first board 26 in one direction, thereby extending the car camping board 20 toward the rear. Next, the end of the second board 28 on one side in the sliding direction is supported by the vehicle body. Here, the end of the second board 28 on one side in the sliding direction is provided with a portion that is supported by a vehicle body support portion 46 provided on the vehicle body. The portion supported by the vehicle body support portion 46 may be shared with the aforementioned hook locking portion 42, or it may be provided separately. As described above, in this embodiment, the space behind the seat back 18 can be covered from above by the car camping board 20. In this way, in this embodiment, the car camping board 20 can function as a tonneau cover.

[0024] Although various embodiments of the present invention have been described above, the present invention is not limited to those described above, and it is of course possible to implement it in various other ways without departing from the spirit of the invention. Furthermore, although the above embodiments described the case in which the present invention is applied to seats for vehicles, the present invention is also applicable to seats for vehicles other than vehicles (for example, aircraft and ships).
