In this embodiment, the rear surface of the seat back 6 and the vehicle interior wall surface WS can be brought into contact with each other by appropriately adjusting the arrangement position of the flip-up mechanism CM. And the urging | biasing part 6c attached to the flip-up shaft 4c can urge | bias a sheet | seat structural member in the direction displaced from a 1st state to a 2nd state.

[Connecting member]
The connecting members (first connecting member 11 and second connecting member 12) are members that connect the seat constituent member and the vehicle interior wall surface WS (see FIGS. 2 to 4). The first connecting member 11 (second connecting member 12) includes a male planar body 11a (12a) and a female planar body 11b (12b).
Each male planar body 11a, 12a is a face material (sheet-like) having a large number of fine hooks on the surface. Each of the female planar bodies 11b and 12b is a surface material (sheet-like) having a large number of fine loops on the surface, and can be brought into surface contact with the male planar bodies 11a and 12a in a detachable manner.
Here, each of the connecting members 11 and 12 can be attached to a seat constituent member (the seat back 6 in this embodiment) or the vehicle interior wall surface WS. Although the attachment method of each connecting member is not particularly limited, various methods such as adhesion, fusion, and sewing can be employed.

In this embodiment, the male planar body 11a of the first connecting member 11 is attached to the back surface (substantially center) of the seat back 6.
The female planar body 11b of the first connecting member 11 is attached to the vehicle interior wall surface WS (frontward) so that the male planar body 11a can be faced with reference to the case where the seat constituent member is in the second state. Deploy. By doing so, the sheet-shaped member is displaced to the second state, whereby the male planar body 11a and the female planar body 11b come into surface contact (engagement).

Further, the male planar body 12 a of the second connecting member 12 is attached to the lower part (substantially the center) of the seat back 6 facing the seat cushion 4. Thus, by disposing the male planar body 12a on the lower side of the seat back 6 (a relatively inconspicuous position), it is possible to avoid the deterioration of the design of the seat as much as possible.
Next, the female planar body 12b of the second connecting member 12 is attached to the vehicle interior wall surface WS (near the rear).

Displaceable. The other side of the female planar body 12b can be detachably attached to the vehicle interior wall surface WS via a detachable member (not shown) (button member, another male planar body, etc.).
And after making a sheet | seat structural member into a 2nd state, the direction orthogonal to the rotational displacement direction D1 of a sheet | seat structural member is enabled by making it possible to face the male planar body 12a while standing up the female planar body 12b. The double-sided body can be brought into surface contact from D2. By doing so, when the sheet constituent member tries to return to the first state, the male planar body 12a and the female planar body 12b suitably resist the stress in the surface direction (shear direction) of the double-sided body. Thereby, a sheet | seat structural member can be maintained suitably in a 2nd state.

[Displacement operation of sheet components]
With reference to FIGS. 1 and 4, the reclining mechanism RM places the seat back 6 forward relative to the seat cushion 4 so as to face each other.
Next, after unlocking the striker S1 and the assembly mechanism, the seat constituent member is rotationally displaced from the first state to the second state via the flip-up mechanism CM. And the 1st connection member 11 connects the seat back 6 back surface and the vehicle interior wall surface WS. At this time, by contacting the back surface of the seat back 6 and the vehicle interior wall surface WS (with a relatively simple operation), the male surface body 11a and the female surface body 11b are brought into surface contact and locked, The seat component can be connected to the vehicle interior wall surface WS.
Further, the second connecting member 12 connects the lower portion of the seat back 6 and the vehicle interior wall surface WS. At this time, the male planar body 12a is brought into surface contact with the male planar body 12a from the direction D2 orthogonal to the rotational displacement direction D1 of the sheet constituent member while raising the female planar body 12b (other side). By doing so, the male planar body 12a and the female planar body 12b can be engaged perpendicularly to the rotational displacement direction D1 of the sheet constituent member (relatively engaged).

As described above, in this embodiment, the seat constituent member is brought into the second state, and then connected to the vehicle interior wall surface WS via the plurality of connecting members 11 and 12. At this time, the male planar bodies 11a, 12a on the seat constituent member side and the female planar bodies 11b, 12b on the vehicle interior wall surface WS side are brought into surface contact with each other and locked (with a relatively simple configuration). Can do.
In this embodiment, the male planar body 12a can be disposed on one side of the seat back 6 facing the seat cushion 4 (a relatively inconspicuous position).
In the present embodiment, when the seat constituent member is connected to the vehicle interior wall surface WS via the second connecting member 12, the male planar body 12a and the female planar body 12b are rotated in the rotational displacement direction of the seat constituent member. Engage perpendicularly to D1 (engage relatively firmly).
Therefore, according to this embodiment, the seat constituent member can be connected to the vehicle interior wall surface WS or the like with a relatively simple configuration.

The vehicle seat of the present embodiment is not limited to the above-described embodiment, and can take other various embodiments.
(1) In the present embodiment, the configuration (size, shape, number of arrangement, arrangement position, etc.) of each of the connecting members 11 and 12 is illustrated, but the configuration of the members is not intended to be limited. The connecting member can be provided at least at a part of the sheet constituting member, and a plurality or a single connecting member can be provided at each part. For example, each planar body can be arranged on one side of the seat cushion facing the seat back (a position where the rear portion or the like is not conspicuous).
Examples of the seat constituent member include various members such as a headrest, an armrest, and a footrest in addition to the seat cushion and the seat back.

(2) In the present embodiment, the example has been described in which the male planar bodies 11a and 12a are attached to the seat component side and the female planar bodies 11b and 12b are attached to the vehicle interior wall surface WS. The arrangement position of each planar body can be changed as appropriate. For example, by attaching a female planar body (a member having a relatively smooth feel) to the sheet component side, the feel of the sheet can be improved.
(3) Moreover, in this embodiment, the example which attaches the female planar body 12b by the side wall surface WS side so that standing was possible was demonstrated. Each planar body can be attached to the seat constituent member side or the vehicle interior wall surface side so as to be able to rise and fall as appropriate. For example, when there is a gap between the seat back and the vehicle interior wall surface, the planar members of both members can be brought into surface contact while standing (so as to fill the gap).

(4) In the present embodiment, the configuration of each mechanism is exemplified, but the configuration of these mechanisms is not limited. For example, in the present embodiment, the configuration of the flip-up mechanism (space-up mechanism) has been illustrated, but the configuration of the mechanism is not intended to be limited. For example, a mechanism (tumble mechanism) in which the rotation axis of the seat cushion is arranged in the width direction can be employed as the flip-up mechanism. And it can connect with other vehicle seats (an example of the 2nd compartment structure), such as jumping up a sheet constituent member by a tumble mechanism.
In addition, the first state in which the vehicle seat is rotated forward and backward by the flip-up mechanism and disposed on the first compartment floor (another example of the first compartment structure), and the first compartment It can also be made displaceable between a second state housed in a second compartment floor surface (another example of the second compartment structure) that is one step lower than the floor surface.
