(16) The seat of the third row has three seats on the right and left sides, but the vehicle storage seat S illustrated in FIG. 1 illustrates a right seat for one person among them. The storage mechanism and the operation method are the same as each other for the left seats for two persons, and in the following description, the vehicle storage seat S which is the right seat will be described.

(17) Further, in the following description, as indicated by the arrows illustrated in FIG. 1, the front to back direction means a front to back direction as viewed from an occupant who sits on the vehicle storage seat S, a width direction means a width direction (a lateral width direction) of the seat cushion 11 of the vehicle storage seat S, and a height direction means a height direction of the seat cushion 11, strictly speaking, a vertical direction of the seatback 12 when the vehicle storage seat S is viewed from the front. Further, the shapes and the arrangement positions of each member described below are the shapes and the arrangement positions when the vehicle storage seat S is in the seatable state, unless otherwise specified.

(18) FIGS. 1 and 2 illustrate a structure of the vehicle storage seat S. As illustrated in FIG. 1, the vehicle storage seat S includes a seat cushion 11 (a seating part) on which the occupant sits and the buttocks of the occupant are supported, a seatback 12 that supports the back of the occupant, and a headrest 13 that supports the head of the occupant. Further, the vehicle storage seat S includes a leg member 20 that supports the seat cushion 11 and includes a locking device 22 at a lower end, and a cover member 30 that covers the front side of the leg member 20. Further, the vehicle storage seat S includes a support member 55 that rotatably supports the rear end of the seat cushion 11. The seat frame F includes a seat cushion frame F1 and a seatback frame F2.

(19) The seat cushion 11 is configured by placing a cushion material 11b on the seat cushion frame F1 illustrated in FIG. 2 and by covering the cushion material 11b with a skin material 11a.

(20) The front side of the seat cushion frame F1 of the seat cushion 11 is supported on the vehicle body floor 4 by the leg member 20. Further, the rear end side of the seat cushion frame F1 is supported to be rotatable in the front to back direction by a support member 55 fixed to the vehicle body floor 4 side.

(21) The seatback 12 is configured by placing a cushion material 12b on a seatback frame F2 illustrated in FIG. 2 and by covering the cushion material 12b with a skin material 12a.

(22) The seatback frame F2 includes two vertically extending side frames disposed to be separated in the right to left direction, and a central frame which is a substantially rectangular frame sandwiched between the side frames.

(23) The headrest 13 is configured by disposing a cushion material 13b on a core material (not illustrated) and by covering the cushion material 13b with a skin material 13a. Further, the skin materials 11a to 13a provided on the vehicle storage seat S are made of, for example, a material such as cloth or leather. Further, the cushion materials 11b to 13b are urethane substrates molded by foam molding using, for example, a urethane foam material.

(24) The leg member 20 illustrated in FIG. 2 supports the front side of the seat cushion frame F1 and is connected to the vehicle body floor 4 side. The leg member 20 is supported on the front side of the seat cushion frame F1 at the upper portion so as to be rotatable in the front to back direction, and when in the seatable state, a locking device 22 detachably connected to the striker 6 provided on the vehicle body floor 4 side is provided at the lower portion of the leg member 20 (see FIG. 4). The locking device 22 is provided with a locking claw 23, and the leg member 20 is fixed to the vehicle body floor 4 by locking the locking claw 23 to the striker 6. When the locking claw 23 rotates about a locking claw rotation axis 24, locking with the striker 6 on the vehicle body floor 4 side is released. When the locked state provided by the locking claw 23 is released, the seat cushion 11 enters a rotatable state in the front to back direction. Further, rotation of the locking claw 23 is biased by a biasing spring (not illustrated) in such a direction that the locked state with the striker 6 is maintained at all times. Although the number of the locking claw 23 provided in the locking device 22 of the present embodiment is one, two or more locking claws 23 may be provided in the locking device 22.

(25) Here, an operation when storing the vehicle storage seat S according to the present embodiment will be described using FIGS. 5A to 5C. The vehicle storage seat S illustrated to FIG. 5A illustrates a seatable state, and a state of being fixed to the vehicle body floor 4 by the locking device. Next, FIG. 5B illustrates a state in which the locking claw 23 of the locking device 22 is released, the headrest 13 is reclined to the seatback 12, and the vehicle storage seat S is advanced to rotate backward. When the rotation is further advanced, the center of gravity of the vehicle storage seat S exceeds a midpoint of the rotation, and thereafter, the vehicle storage seat S is rotated backward by its own weight to reach the stored state as illustrated in FIG. 5C. In the stored state, the leg member 20 and the cover member 30 are folded to the seat cushion 11 side.

(26) FIG. 6 illustrates a state in which the vehicle storage seat S is stored, the opening part of the storage recess 5 becomes a flat surface integral with the back surface of the seat cushion 11 so that a wide loading space can be secured. At this time, the leg member 20 and the cover member 30 for covering the front surface thereof are exposed to the vehicle body floor 4 on the back surface of the seat cushion. An opening part 31 is formed in the cover member 30 at a position that overlaps with the locking device 22 in order to lock the locking device 22 of the leg member 20 to the striker 6. However, since the opening part 31 is exposed to the vehicle body floor 4 in the stored state, there is a risk of entry of foreign matter from the opening part 31. The cover member 30 of the vehicle storage seat S is provided with an elastically deformable lip part 40 that covers the opening part 31. By providing the lip part 40, the opening part 31 is closed in the stored state, and the entry of foreign matter from the opening part 31 is suppressed. Further, even in the seatable state, since the lip part 40 is elastically deformed, the striker 6 can be inserted into the opening part 31 and the locking claw 23 of the locking device 22 can be locked to the striker 6.

(27) The cover member 30 and the lip part 40 will be described in more detail using FIGS. 7 to 9. As illustrated in FIG. 7, in the cover member 30, the opening part 31 into which the striker 6 is inserted is formed, and the elastically deformable lip part 40 that covers the opening part 31 is provided. The opening part 31 is formed at a position of the cover member that overlaps with the locking device 22. The opening part 31 is disposed at a position out of the center of the cover member 30 in the width direction. When the opening part 31 is provided, since the height of the cover member 30 is reduced, the rigidity is lowered. Therefore, the rigidity of the cover member as a whole can be improved, by avoiding the formation of the opening part 31 at the center in the width direction on which the load is concentrated, and by suppressing the decrease in the rigidity at the central portion of the cover member 30. Further, in the present embodiment, the width direction of the cover member 30 is the same as the width direction of the vehicle storage seat S.

(28) In addition, the cover member 30 is provided with a bead portion 33 around the opening part 31. When the striker 6 is inserted and the lip part 40 is elastically deformed, a deformation pressure is applied to the opening part 31. However, since the rigidity is improved by providing the bead portion 33 around the opening part 31, deformation of the opening part 31 can be suppressed. Further, the cover member 30 is formed with a plurality of bead portions 33 extending in the vertical direction in the seatable state. By providing the plurality of bead portions 33, the rigidity of the cover member 30 is improved.

(29) The lip part 40 is located at the rear of the front surface of the cover member 30 as illustrated in FIG. 8. Further, a contact surface 32 at which the lip part 40 and the cover member 30 contact with each other is inclined as illustrated in FIG. 8. Since the contact surface 32 is inclined, a contact area becomes larger than in the case of planar contact, and the contact can be performed firmly. In addition, the lip part 40 is located at the rear of the front surface of the cover member 30. In other words, the front surface 45 of the lip part 40 is retreated to form a recess. Therefore, for example, when the vehicle storage seat S is in the stored state, since the lip part 40 is exposed on the vehicle body floor 4 but is a recess, the luggage carried on the vehicle body floor 4 is prevented from coming into direct contact with the lip part 40. Thus, deterioration of the lip part 40 is suppressed.

(30) As illustrated in FIG. 7, when the vehicle storage seat S is in the seatable state, a first slit 41 extending upward from the lower end, and a second slit 42 intersecting with the first slit 41 in a T-shape and extending in the width direction of the cover member 30 are formed in the lip part 40. Further, a notch 44 is formed at an intersection of the first slit 41 and the second slit 42. A notch 43 is formed at the lower end of the first slit 41. The width of the notch 43 is larger than the width of the striker 6 so that the striker 6 can be easily inserted into the first slit 41. In addition, the width of the first slit 41 is preferably smaller and is at least smaller than the width of the striker 6. Therefore, the entry of foreign matter from the first slit 41 is suppressed in the stored state. In addition, although the T-shaped slit is formed in the lip part 40 of this embodiment, the second slit 42 may be omitted and the first slit 41 may be formed in an I-shape. A circular hole may be formed instead of the second slit 42.

(31) A plurality of protruding parts 47 is formed on the back surface 46 of the lip part 40, that is, the surface of the leg member 20 facing the locking device 22. Although noise may occur when the elastically deformable lip part 40 and the locking device 22 come into contact with each other, since the area of direct contact decreases by providing the plurality of protruding parts 47, it is possible to suppress an occurrence of the noise.

(32) As illustrated in FIGS. 3 and 10, in the vehicle storage seat S of the present embodiment, a seat plate 50 is provided on the lower surface of the seat cushion 11 so that the lower surface becomes planar when stored. Further, as illustrated in FIG. 10, the seat plate 50 is provided with a housing part 52 that houses the leg member 20 and the cover member 30.

(33) Further, on the lower surface of the seat cushion 11, a grip portion 51 formed in a concave shape is provided so that a finger can be easily applied. The grip portion 51 is provided so as to be located at the front of and above the cover member 30 when the vehicle storage seat S is in the seatable state. Therefore, when in the seatable state, the occupant can easily lift the seat cushion 11 by inserting a finger into the grip portion 51 and gripping the front end of the seat cushion 11. Further, by providing the grip portion 51 at the front of the cover member 30, the leg member 20 does not interfere with the grip portion 51, and the occupant can easily insert a hand into the grip portion 51.

(34) Although the lip part 40 of the present embodiment is made of acrylic rubber, the material of the lip part 40 is not limited thereto, and the lip part 40 may be made of fluororubber, silicone rubber, hydrogenated nitrile rubber or the like.

(35) The embodiment of the present invention has been described above, while referring to the drawings. In the above embodiment, the vehicle storage seat mounted on a vehicle has been described as a specific example, but the vehicle storage seat is not limited to a vehicle, the vehicle storage seat can also be provided as a seat for trains, buses, and the like, and can also be used as a seat for airplanes and ships.

(36) In addition, although the vehicle storage seat that can be rotated backward and stored has been described, a cover member to which a lip part is attached may be applied to the leg member of the vehicle storage seat that can be rotated forward and stored. Further, the vehicle storage seat may be rotated not only in the front to back direction but also in the lateral direction.
