FIG. 1 is an external perspective view of a vehicle seat according to this embodiment.
The vehicle seat of this embodiment is a rear seat installed at the rear part of the vehicle interior. This rear seat is divided in a left-right direction at a predetermined ratio (for example, 4 to 6), and includes a narrow left rear seat 1A and a wide right rear seat 1B. The left and right rear seats 1A and 1B have the same basic structure and function, although they differ from each other in that each mechanism is disposed at a position where the left and right mechanisms are reversed and in the width in the vehicle width direction.

The rear seats 1A and 1B include a seat cushion 11 that supports the occupant's buttocks, a seat back 12 that supports the back of the occupant, and a headrest 13 that supports the head of the occupant. The rear seats 1A and 1B can be arranged in three types of seat arrangements, a seatable state, a tip-up state, and a dive-down state, which will be described in detail later.
2 to 4 are side views of the rear seat 1A as viewed from the left side, FIG. 2 shows a case where the rear seat 1A is seatable, FIG. 3 shows a case where the rear seat 1A is in a tip-up state, and FIG. The rear seat 1A is shown in a dive-down state.

  The vehicle of this embodiment is a vehicle having a so-called center tank layout in which a thin fuel tank (not shown) is disposed below a front seat (not shown), and the vehicle body between the front seat and the rear seats 1A and 1B. The floor (the vehicle floor at the front foot of the rear seats 1A and 1B) is formed sufficiently lower than the vehicle floor under the front seat. This body floor portion is referred to as a lower floor 15. A higher floor 16 higher than the lower floor 15 is continuously provided on the rear side of the lower floor 15 via a stepped portion 17.

  A plurality of support brackets 18 project from the upper surface of the higher floor 16 so as to be spaced apart from each other in the vehicle width direction, and the lower ends of the seat backs 12 of the rear seats 1A and 1B are provided on the support bracket 18 via a support shaft 19. It is attached so that it can rotate back and forth. The seat cushions 11 of the rear seats 1 </ b> A and 1 </ b> B are rotatably attached to corresponding seat backs 12 via a substantially L-shaped turning arm 20. Specifically, the substantially L-shaped rotation arm 20 has one end side fixed to the side portion of the seat cushion 11 and the other end side attached to the side portion of the seat back 12 so as to be rotatable via the support shaft 21. ing. The support shaft 21 is set at a sufficiently high position of the seat back 12 that is upright (a position that is approximately one third of the height from the lower end side of the seat back 12).

  Each of the rear seats 1A and 1B is in a seatable state in which the seat cushion 11 is deployed about 90 degrees forward with respect to the standing seat back 12 by the rotation of the seat cushion 11 about the support shaft 21 (see FIG. 2). Then, it can be switched to a tip-up state (see FIG. 3) in which the seat cushion 11 is flipped upward with respect to the standing seat back 12.

  A support leg 22 made of a substantially U-shaped frame material is rotatably attached to the lower surface of the seat cushion 11 in a seatable state near the front. The support leg 22 is rotatably attached to the seat cushion 11 at the base end side of the parallel extending pieces 22b and 22b of the substantially U-shaped frame material, and the distal end side of the extending pieces 22b and 22b is the lower floor 15. Are connected by an end shaft 22a that is substantially parallel to. Further, the support leg 22 extends downward from the lower surface of the seat cushion 11 in a seatable state and is rotated rearward from the deployed state so as to be substantially parallel to the lower surface of the seat cushion 11. It is possible to switch to the folded state, and in these two states, the rotation position is fixed by a locking mechanism (not shown). The support leg 22 is maintained in the unfolded state when the seat cushion 11 is in a seatable state, and the end shaft 22 a is supported on the lower floor 15 via the leg receiving member 23.

  The leg support member 23 is fixedly installed at a position close to the stepped portion 7 on the lower floor 15, but the leg support member 23 is located in a substantially central region in the width direction of the end shaft 22 a of each support leg 22. It is provided at the corresponding position. As shown in FIG. 2, when the seat cushion 11 is in a seatable state, a relatively wide space is ensured between the upper surface of the region extending from the high floor 16 to the stepped portion 17 and the lower surface of the seat cushion 11, and this space.

  When the seatable state shown in FIG. 2 is switched to the tip-up state shown in FIG. 3, the end shaft 22a of the support leg 22 is removed from the leg receiving member 23, and the support leg 22 is folded in this state. The cushion 11 is flipped upward about the support shaft 21 and rotated.

  When the seatable state shown in FIG. 2 is switched to the dive-down state shown in FIG. 4, the support leg 22 is attached to the leg support member 23 while the seat back 12 is tilted forward about the support shaft 19. The support leg 22 and the seat cushion 11 are bent in the folding direction while being rotated forward about the center. Thus, when the seat cushion 11 is completely tilted forward, the front surface of the upper region of the seat back 12 is superposed on the upper surface of the seat cushion 11, and the seat cushion is placed in the concave space formed by the lower floor 15 and the step portion 17. 11 and a part of the seat back 12 are dropped. As a result, the back surface of the seat back 12 is smoothly continuous with the upper surface of the higher floor 16.

  In addition, a seat lock mechanism 24 for fixing the seat back 12 to the vehicle body side in a standing posture is provided at a side portion of each seat back 12, and the seat back 12 is raised to the rear side to a predetermined angle. Sometimes, a striker (not shown) on the vehicle body side is locked and fixed to a lock lever (not shown) in the seat lock mechanism 24. During the dive down described above, the lock by the seat lock mechanism 24 is released, and the seat back 12 is tilted forward.

  By the way, a resin cover member 26 for opening and closing the opening 25 (see FIGS. 5 and 6) of the frame portion of the support leg 22 and the front side of the article storage space S is attached to each support leg 22 of the rear seats 1A and 1B. It has been. The cover member 26 is formed in a horizontally long, substantially rectangular shape so as to cover the front side of the support leg 22 in a seatable state and the substantially front side below the seat cushion 11. Hereinafter, when the cover member 26 covers the front of the support leg 22 in a seatable state, the lower side is referred to as “below” of the cover member 26, and the upper side is referred to as the cover member 26. It shall be called “up”.

FIG. 5 is a view showing a state in which the cover member 26 is opened with respect to the right rear seat 1B in the seatable state, and FIG. 6 is an enlarged view of a portion A in FIG.
As shown in these figures, a substantially U-shaped opening 27 is provided in a region corresponding to the leg receiving member 23 on the lower floor 15 at the lower edge of the cover member 26, and both left and right sides of the opening 27 are provided. A locking hook 28 that is rotatably held by the end shaft 22 a of the support leg 22 is integrally extended at the edge. Each locking hook 28 extends on the back side of the cover member 26. The cover member 26 is pivotally attached to the end shaft 22a by the locking hook 28, and is pivotable forward about the end shaft 22a.

  Further, locking brackets 29 are respectively attached to the extending pieces 22b, 22b on both sides of the support leg 22 that are connected to the end shaft 22a, and the positions corresponding to the locking brackets 29 on the back surface of the cover member 26 are engaged with each other. A locking hook 30 that can be engaged with the locking bracket 29 is projected. When the cover member 26 is stacked on the front surface of the support leg 22 so as to close the opening 27, the lock hook 30 is engaged with the corresponding lock bracket 29 to hold the cover member 26 in a closed state. The cover member 26 has curved edges 26a that are gently curved on the rear side of the rear seats 1A and 1B when the cover member 26 is closed in a seatable state at the left and right ends and the lower end of the cover member 26. Yes.

FIG. 7 is a perspective view of the rear seats 1A and 1B when the seat cushion 11 is in the tip-up state.
As shown in the figure, a resin under cover 31 is provided on the lower surface of the seat cushion 11, and the support cover 22 and the cover member 26 are provided on the under cover 31 when the support legs 22 are folded. A recess 32 is formed in which a part is accommodated. The recess 32 is formed in a stepped shape with respect to the general surface 31a on the lower surface of the under cover 31 on the front edge side, and in a state where the support leg 22 is completely folded (folded state), The front surface is set to be substantially flush with the general surface 31 a of the undercover 31.

The rear seats 1A and 1B according to this embodiment are configured such that the support leg 22 extending downward from the lower surface of the seat cushion 11 in the seatable state as described above, the upper surface of the region extending from the higher floor 16 to the stepped portion 17 and the seat cushion 11. Since the cover member 26 for opening and closing the article storage space S between the lower surfaces of the seat cushion 11 is attached, the cover member 26 is larger below the seat cushion 11 in the seatable state than when the article storage portion is provided on the lower surface of the seat cushion 11. Articles can be stored.
In the rear seats 1 </ b> A and 1 </ b> B, the article 40 can be easily inserted into and removed from the article storage space S from the front side of the support leg 22 with the seat cushion 11 being in a seatable state by opening the cover member 26. In addition, by closing the cover member 26 from this state, the lower part of the seat cushion 11 is covered with the cover member 26, and the appearance from the outside can be improved.

  In particular, in the rear seats 1A and 1B of this embodiment, the cover member 26 is rotatably attached to the end shaft 22a of the support leg 22 that extends substantially parallel to the lower floor 15 on the distal end side. Therefore, as shown in FIGS. 5 and 6, the article 40 can be taken into and out of the article storage space S by tilting the cover member 26 toward the lower floor 15. Therefore, in the case of the rear seats 1A and 1B, when the occupant performs the work for putting in / out the article 40 from the front obliquely upper side of the seat cushion 11, the article 40 is less likely to interfere with the cover member 26, and the article can be put in and taken out more easily. There is an advantage of being.

  Further, in the rear seats 1A and 1B, the lower surface of the seat cushion 11 is provided with a recess 32 in which the support leg 22 and a part of the cover member 26 are accommodated when the support leg 22 is folded. Since the front surface of the cover member 26 is set to be substantially flush with the general surface 31a of the lower surface of the seat cushion 11 in a state where the legs 22 are folded, the lower side of the seat cushion 11 in the seatable state In the chip-up state, a large space with little unevenness can be secured on the front side of the seat cushion 11. Therefore, in the case of the rear seats 1A and 1B, in the tip-up state, a large load can be mounted on the lower floor 15 on the front side of the rear seats 1A and 1B, and the appearance when viewed from the front side is improved. can do.
