The lock member 16 is swingably supported on the casing 7 a of the lock mechanism 7 via a support shaft 17. A torsion coil spring 18 is provided around the support shaft 17. The torsion coil spring 18 urges the lock member 16 in the direction C1 that engages the protrusions 21 to 24.

  The strength with which the lock member 16 and the protrusions 21 to 24 are engaged is set to such a strength that the lock is released when the movable member 26 of the release mechanism 8 to be described later protrudes to push the tonneau board 6. . The occupant can also release the lock by pushing down the second end portion 6b on the rear end side of the tonneau board 6 and rotating the tonneau board 6.

  The lock mechanism 7 of the present embodiment includes a third protrusion 23 for holding at the third position P3, and can hold the tonneau board 6 at a third position P3 between the first position and the second position. it can. For this reason, even if the vehicle is driven when the tonneau board 6 is in the third position, there is no problem such as the tonneau board 6 swinging and rattling.

  Even if the third protrusion 23 for the third position P3 is omitted, the tonneau board 6 can be moved from the first position P1 to the second position P2. In this case as well, in the present embodiment, since the seat back 11 is tilted backward, the tonneau board 6 is moved to the third position P3 where the seat back 11 hangs vertically due to its own weight. In the present invention, the lock mechanism 7 only needs to hold the tonneau board 6 at least at the second position P2, and the function of holding the tonneau board 6 at the third position P3 can be omitted.

  Moreover, the 3rd position P3 of the tonneau board 6 can be changed arbitrarily by changing suitably the space | interval which arrange | positions the protrusions 21-24. Details will be described later in a second embodiment.

  The release mechanism 8 is a mechanism that releases the holding of the tonneau board 6 at the second position P2 by the lock mechanism 7 and moves the tonneau board 6 to a third position P3 between the first position P1 and the second position P2. The release mechanism 8 is disposed so as to be embedded in the back surface 11 a of the seat back 11.

  Specifically, the release mechanism 8 includes a casing 25, a movable member 26, and a compression coil spring 27, as shown in FIG. 2A and FIG. 3.

  Inside the casing 25, a first space portion 25a having a small inner diameter and a second space portion 25b having a large inner diameter are formed.

  The movable member 26 moves the tonneau board 6 to the third position P3 by moving in and out of the casing 25 when receiving an operation force by the occupant's hand.

  The movable member 26 has a locking portion 28 and a magnet portion 29, and is located between a position protruding from the casing 25 shown in FIG. 3 and a housed position shown in FIG. 4 (b). It is possible to move.

The locking part 28 is inserted into the first space 25a of the casing 25 so as to be able to appear and retract. When the locking portion 28 is pushed into the first space portion 25a once by the occupant's hand through the tonneau board 6 and the magnet portion 29, a locking protrusion or locking recess (not shown) inside the first space portion 25a. ) Is locked, and when it is pushed once more, the lock is released, and a part of the tip protrudes from the first space portion 25 a by the elastic force of the compression coil spring 27.

  The magnet portion 29 is fixed to the tip of the locking portion 28, and is inserted into the second space 25b so as to be able to appear and retract. Each time it is pushed together with the locking portion 28, it moves between the storage position and the protruding position. The magnet portion 29 contains a permanent magnet. On the other hand, a magnetic plate 30 made of a plate magnetic material such as steel is provided on the facing surface 6c of the tonneau board 6 facing the back surface 11a of the seat back 11. Thereby, the magnet part 29 can hold | maintain the tonneau board 6 in the 2nd position P2 of a retracted state on the back surface 11a of the seat back 11 with the holding | maintenance by the locking mechanism 7 by adsorb | sucking the magnetic board 30. FIG. .

  Note that the tonneau board 6 at the second position P2 in the retracted state may be locked only by the attractive force of the magnet portion 29. In this case, the magnet portion 29 can function as the locking means of the present invention.

  The back door 5 is a door that is rotatably disposed via a hinge (not shown) on the rear side of the vehicle body 1 in the luggage compartment 4 and covers the rear opening 31 of the vehicle body 1 so as to be openable and closable. The back door 5 of the present embodiment opens and closes up and down, but may be opened laterally.

  As shown in FIGS. 1 to 3, when the tonneau board 6 is in use, the tonneau board 6 rotates from the back surface 11 a of the seat back 11 around the rotation shaft 12 to the first position P 1 that is substantially horizontal to the cargo compartment floor 4 a. Moved. At this time, the first protrusion 21 of the lock mechanism 7 is held in the first position P <b> 1 by engaging with the lock member 16. Thereby, the inside of the luggage compartment 4 can be covered with the tonneau board 6.

  Further, when the back door 5 is closed with the tonneau board 6 in the first position P1, the second end portion 6b (see FIG. 1) on the rear end side of the tonneau board 6 is supported by the protrusion 32 of the back door 5. ing. Therefore, the tonneau board 6 in the first position P1 is supported by the seat back 11 at the front end side and supported by the back door 5 at the rear end side, so that both ends are supported. As a result, when the back door 5 is in a closed state while allowing the tonneau board 6 to rotate between the first position P1 and the second position P2, the back door 5 causes the second end 6b on the rear end side of the tonneau board 6 to be closed. The tonneau board 6 can be held in the horizontal position (first position P1).

  Further, since the lock mechanism 7 can hold the tonneau board 6 in the first position P1, when the tonneau board 6 is in the use position and there is a luggage under the tonneau board 6, the tonneau board 6 and the luggage Interference can be prevented and damage to the tonneau board 6 can be prevented.

  On the other hand, as shown in FIGS. 4A and 4B, in the retracted state of the tonneau board 6, the tonneau board 6 rotates around the rotating shaft 12 to a state along the back surface 11 a of the seat back 11 to the second position P <b> 2. Moved to. At this time, the second protrusion 22 of the lock mechanism 7 is held in the second position P <b> 2 by engaging with the lock member 16. By storing the tonneau board 6 on the back surface 11 a of the seat back 11, a large amount of luggage B can be loaded in the luggage compartment 4.

  When the tonneau board 6 is in the second position P2, the movable member 26 of the release mechanism 8 is accommodated in the casing 25, and the magnet portion 29 attracts the magnetic plate 30 on the tonneau board 6 side.

When the tonneau board 6 moves from the first position P1 in the use state to the second position P2 in the retracted state, the tonneau board 6 is pushed down by the passenger's hand and rotated to temporarily reach the third position P3 (see FIG. 5). Then, the tonneau board 6 may be pushed to the second position P2 from the rear of the vehicle to the front using a nearby baggage or other object.

  The length of the tonneau board 6 of this embodiment is set to be equal to the distance from the seat back 11 to the back door 5 at the rear end of the vehicle, and substantially the same as the vertical width of the seat back 11. Therefore, the tonneau board 6 is disposed from the seat back 11 to the back door 5 when in the first position P1, and is arranged so as to be substantially the same as the vertical width of the seat back 11 when in the second position P2. It is installed. Therefore, the tonneau board 6 can completely cover the luggage compartment 4 over the entire length in the front-rear direction of the vehicle in the first position, and can be completely stored in the back surface 11a of the seat back 11 in the second position. . Therefore, since the cargo compartment 4 can be completely covered with the single tonneau board 6, the number of parts can be reduced, and the tonneau board 6 can be stored in the seat back 11 as it is, so that the storing operation is also easy.

Next, as shown in FIGS. 5A and 5B, when the tonneau board 6 is moved from the second position P2 in the retracted state to the first position P1 in the used state, the release mechanism 8 is operated. Then, the lock mechanism 7 is released and the tonneau board 6 is moved to the third position.

  Specifically, the occupant pushes the vicinity of the release mechanism 8 on the back of the tonneau board 6 from the rear of the vehicle body 1 with a hand or the like. As a result, the movable member 26 of the release mechanism 8 is unlocked by the locking portion 28 and protrudes toward the vehicle rear side by the elastic force of the compression coil spring 27. When the movable member 26 protrudes, the lock mechanism 7 that holds the tonneau board 6 in the retracted state of the second position P2 stored in the back surface 11a of the seat back 11 is released, and at the same time, the first position P1 and the first position The tonneau board 6 is moved to the third position P3 between the two positions P2, that is, the position where the occupant's hand can easily reach from the rear of the vehicle body 1 than the second position P2. At this time, the tonneau board 6 is held at the third position P3 by the third protrusion 23 of the lock mechanism 7 engaging with the lock member 16.

  Therefore, the rear opening 31 of the vehicle body 1 is used when the tonneau board 6 is shifted from the stored state of the second position stored in the back surface 11a of the seat back 11 to the used state of the first position P1 that covers the cargo floor 4a substantially horizontally. The occupant extends his / her hand and pushes the movable member 26 of the release mechanism 8 forward through the tonneau board 6 so that the tonneau board 6 is located on the vehicle rear side of the second position P2 and at the first position P1. It is possible to shift to the close third position P3 with one touch. Thereafter, the passenger can easily move the tonneau board 6 at the third position P3 to the first position P1 by lifting it up by hand.

  In the present embodiment, the release mechanism 8 is disposed at a position above the lower end of the seatback 11 tilted backward. Such arrangement of the release mechanism 8 makes it easier to reach the release mechanism 8 from the rear portion of the vehicle body 1. As a result, by operating the release mechanism 8 arranged on the upper portion of the seat back 11, the lock of the tonneau board 6 at the second position P2 by the lock mechanism 7 can be released more easily.

  Further, as shown in FIGS. 6A and 6B, the tonneau board 6 of the present embodiment has a front seat 40 that is disposed to be separated from the rear seat 3 forward when the seat back 11 is in the forward-turned state. The front seat 40 is supported by the seat back 11 so that the front seat 40 and the rear seat 3 can be connected. Therefore, when it is desired to use the luggage compartment 4 as widely as possible with the seat back 11 in the forward-turned state, the gap 41 between the front seat 40 and the rear seat 3 can be filled with the tonneau board 6. As a result, it is possible to load a load such as a long object L to the maximum extent. At this time, the tonneau board 6 is held at the fourth position P4 by the fourth protrusion 24 of the lock mechanism 7 engaging with the lock member 16.

  Further, in such a usage state, the front seat 40 is moved to the position closest to the vehicle front side. And since the 2nd end part 6b of the tonneau board 6 is supported by the seat back 42 of the front seat 40, the tonneau board 6 will be in the state of the stable both-ends support.

  As shown in FIG. 7, when the long object L2 has a length that fits between the cargo compartment 4 and the front seat 40, the seat of the rear seat 3 is not moved to the front side of the vehicle. The long object L2 may be accommodated using the space from the luggage compartment 4 to the seat back 42 of the front seat 40 with the back 11 moved forward. In this case, it is preferable to move the tonneau board 6 to a position where it leans against the seat back 42 of the front seat 40 so that the tonneau board 6 is not crushed by the long object L2.

However, the present invention is not limited to this, and the intermediate position of the tonneau board 6 can be changed by changing the position of the protrusion of the lock mechanism 7.

  That is, as a second embodiment of the present invention, as shown in FIGS. 8A and 8B, the intermediate position after the change of the tonneau board 6 is slightly upward from the third position P3 in FIG. You may make it hold | maintain the tonneau board 6 in the open position, ie, the 3rd position P31 after a change. In this case, since the lock mechanism 7 holds the tonneau board 6 in the changed third position P31, the changed third protrusion 43 is closer to the first protrusion 21 than the third protrusion 23 in FIG. 21 is provided at a close position. In this case, the elastic force of the compression coil spring 27 of the release mechanism 8 needs to be strong enough to jump up the tonneau board 6 to the third position P31 after the change.

  In this way, when the middle position of the tonneau board 6 is changed to the third position P31 after being changed slightly upward, as shown in FIG. It becomes possible to cover with the tonneau board 6.

  As a procedure for placing the luggage S, for example, the tonneau board 6 at the third position P31 after the change is slightly opened by the passenger's hand from the rear of the vehicle, the luggage S is placed at a position close to the seat back 11 of the luggage compartment 4, and then The tonneau board 6 may be returned to the changed third position P31. At this time, as shown in FIG. 8B, the tonneau board 6 is held at the third position P31 after the change by engaging the third protrusion 43 after the change of the lock mechanism 7 with the lock member 16. Therefore, there is no problem that the tonneau board 6 swings during operation.
