Description

[Technical Field]

[0001] The present invention relates to a vehicle seat, and more particularly to a vehicle seat in which a seat body having a seat back and a seat cushion can be switched between an in-use state and a stowed state. [Background technology]

[0002] BACKGROUND ART Conventionally, there is known a vehicle seat that can be switched between a use state in which an occupant can be seated and a storage state in which the seat back is folded and the seat body is stored on the vehicle floor side (see, for example, Patent Document 1).

[0003] The vehicle seat described in Patent Document 1 has a cover structure in which a gap between the seat back and the seat cushion is covered with a cover member, and the cover member itself can be folded to make it expandable and contractible. Specifically, the cover structure includes a cover member connected to the lower end of the seat back and the rear end of the seat cushion so as to cover the gap between them, and the cover member is configured to fold at a folding portion at the middle part of the cover member in response to dimensional changes in the gap caused by relative movement of the seat back and the seat cushion. Therefore, even when the state of the seat body is changed, the gap between the seat back and the seat cushion can be covered and hidden without impairing the appearance.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-204634 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, in a vehicle seat equipped with a cover structure such as that of Patent Document 1, gaps that occur between the seat bodies can be effectively covered and concealed even when the state of the seat body is switched, but because the cover structure is made up of multiple components, there is a risk that the assembly labor will increase, and that costs and weight will increase. Furthermore, in the above-mentioned cover structure, in order to make the cover member foldable, multiple resin boards are attached to the cover body (skin material), and an elastic body that applies a tensile force is also attached, which may result in the cover structure becoming larger, and ultimately the seat becoming larger. Furthermore, if the elastic force (tensile force) of the elastic body decreases due to deterioration over time or repeated use, it may become difficult to fold the cover member smoothly.

[0006] The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a vehicle seat equipped with a cover member having a simple structure that can cover gaps that occur between the seat bodies even when the state of the seat bodies is switched. Another object of the present invention is to provide a vehicle seat that can suitably cover and conceal gaps between the seat bodies without compromising the appearance of the seat and in which the cover members are compactly arranged. [Means for solving the problem]

[0007] The above-mentioned object is achieved by a vehicle seat of the present invention, which provides a vehicle seat including a seat body having a seat back and a seat cushion, and which is switchable between a use state in which an occupant can be seated and a storage state in which the seat back is folded and the seat body is moved toward a vehicle body floor, the vehicle seat including a cover member extending downward from a rear surface of the seat back and covering a gap in a vertical direction between the seat back and the seat cushion or the vehicle body floor, the cover member including a first extension member extending from the rear surface of the seat back and deformable in response to a folding action of the seat back, and a second extension member extending downward from an extension end of the first extension member and covering the gap, a base end of the first extension member being attached to a rear surface of a lower part of the seat back, and an extension end of the second extension member being attached to a rear part of the seat cushion or a rear part of a base member that supports the seat body from below, and in the use state, at least a part of the first extension member being stored between the seat back and the second extension member, and the first extension member of The base end , the first extension member This problem is solved by the first extension member being disposed at a position lower than the extension end portion, and being exposed to the outside in the stored state.

[0008] With the above configuration, gaps that occur between the seat bodies can be suitably covered even when the state of the seat body is switched, and a vehicle seat equipped with a cover member having a simple structure can be realized. Specifically, the cover member has a simple structure including a deformable first extension member and a second extension member. The vehicle seat deforms the first extension member in response to the switching operation of the seat body, and stores the first extension member in the in-use state and covers the gap with the second extension member, and exposes the first extension member in the stowed state and covers the gap with the first and second extension members. In this way, the cover member can effectively cover and conceal the gap that occurs between the seat bodies.

[0009] In this case, the first extension member abuts against the rear surface of the seat back, and when switching between the use state and the storage state, the abutment surface of the first extension member that abuts against the seat back switches between the front surface and the back surface. With the above configuration, even when the state of the seat body is switched, the first extension member of the cover member is kept in contact with the rear surface of the seat back, allowing the cover member to be arranged compactly. Furthermore, when the seat body is switched, the cover member (first extension member) can be deformed to suitably follow the seat body (seat back).

[0010] At this time, the base end portion of the first extension member is in the stored state. The first extension member It is preferably disposed at a position above the extension end portion, and when switching from the stored state to the use state, it moves to a position in front of the seat than the position in the stored state. The seatback may also be provided with a reclining device that rotatably connects the seatback to the vehicle floor or the seat cushion and locks the rotational movement of the seatback, the reclining device having a rotation axis that serves as the rotation center of the seatback, and the base end of the first extension member being positioned in front of the seat relative to the rotation axis when in the used state. With the above configuration, when the seat body is switched from the stored state to the used state, the first extension member can be suitably stored between the seat back and the second extension member. Therefore, the gap between the seat bodies can be suitably covered without impairing the appearance of the seat (without the first extension member being unintentionally exposed). In addition, the cover member can be arranged compactly.

[0011] In this case, it is preferable that, in the use state, the first extension member is stored between the seat back and the second extension member, and the rear surface of the seat back and the second extension member are in contact with each other. In addition, in the stored state, it is preferable that the first extension member is exposed to the outside and the rear surface of the seat back and the second extension member are in contact with each other. With the above-described configuration, the gaps between the seat bodies can be appropriately covered and concealed while ensuring the design of the seat without compromising the appearance of the seat. Also, the cover member can be arranged more compactly.

[0012] In this case, the seat may be provided with a base member that supports the seat body from below, and a reclining device that rotatably connects the seat back to the base member and locks the rotational movement of the seat back, and the extension end of the second extension member is attached to the rear portion of the base member, and the second extension member moves in the fore-and-aft direction of the seat relative to the base member when switching from the stored state to the use state. With this configuration, when the seat body is switched from the stored state to the used state, the first extension member is deformed and the second extension member is moved in the front-rear direction of the seat accordingly, thereby more effectively covering up gaps that occur between the seat bodies.

[0013] In this case, it is preferable that the first extension member is deformed in response to the folding operation of the seat back, and is disposed so as to follow the rear surface of the seat back when in the stored state. With the above configuration, the appearance of the seat can be improved without impairing the appearance of the seat when in the stored state.

[0014] In this case, it is preferable that the seat body is provided with a base member that supports the seat body from below, the second extension member has a folded portion formed at the extension end of the second extension member and folded upward from the extension end, and the folded portion of the second extension member is attached to the rear portion of the base member. With the above configuration, when the seat body is switched, the second extension member can be suitably moved in the front-rear direction of the seat in accordance with the movement of the seat body. Also, when the seat body is switched, the second extension member can be prevented from unintentionally bending backward.

[0015] In this case, it is preferable that the first extending member is made of a flexible member, and the second extending member is made of a plate-shaped member. With the above configuration, it is possible to realize a cover member that has a simpler structure and is capable of suitably covering and concealing gaps that occur between the seat bodies. [Effects of the Invention]

[0016] According to the present invention, it is possible to realize a vehicle seat equipped with a cover member having a simple structure that can suitably cover gaps that occur between the seat bodies even when the state of the seat body is switched. Furthermore, according to the present invention, the cover member can be arranged compactly, and the cover member can be deformed to suitably follow the seat body when the seat body is switched. Furthermore, according to the present invention, the gaps between the sheet bodies can be suitably covered and concealed without impairing the appearance of the sheet (without the first extending member being unintentionally exposed) and while ensuring the design of the sheet. Furthermore, according to the present invention, the appearance of the seat can be improved without impairing the appearance of the seat when in the stored state. According to the present invention, the second extending member can be suitably moved in the front-rear direction of the seat in accordance with the movement of the seat body, and the second extending member can be prevented from unintentionally bending backward.

[0018] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to an invention of a vehicle seat that can be switched between a "use state" and a "storage state," and is provided with a cover member that extends downward from the rear surface of the seat back and covers the gap in the vertical direction between the seat back and the seat cushion, and the cover member has a first extension member that can deform in response to the folding action of the seat back, and a second extension member that extends downward from the extension end of the first extension member and covers the gap, and is mainly characterized in that when in the "use state," the first extension member is stored between the seat back and the second extension member, and when in the "storage state," the first extension member is exposed to the outside. The side of the seat back of a vehicle seat on which an occupant sits is the front side of the seat.

[0019] The vehicle seat S of this embodiment is, for example, a rear seat corresponding to the rear seat of a vehicle, as shown in Fig. 1. Note that it can also be used as a middle seat in the second row in a vehicle that has three rows of seats in the longitudinal direction of the vehicle. As shown in Figures 3 and 4, the vehicle seat S can be arranged in two different configurations: an "used state" in which an occupant can sit, and a "stored state" in which the seat back is folded and the seat body is stored on the vehicle floor side. Specifically, when the occupant pulls the reclining operation lever 44 at the top end of the seat body, the vehicle seat S switches from the "used state" shown in Fig. 3 to the "stored state" shown in Fig. 4, in which the seat body is tilted forward and folded and stored on the vehicle floor. Then, the occupant manually raises the seat body from the stored state to return to the "used state." In addition, the vehicle seat S can be switched between a "normal state" in which the seat is positioned at a reference position in the fore-and-aft direction, and a "sliding state" in which the seat body is slid to a predetermined position in the fore-and-aft direction.

[0020] As shown in Figures 1 and 2, the vehicle seat S comprises a seat body having a seat back 1, a seat cushion 2, and a headrest 3, a base member 30 that supports the seat body from below, a reclining device 40 that rotatably connects the seat back 1 to the base member 30 and locks the rotational movement of the seat back 1, and a rail device 50 that is attached between the vehicle floor and the base member 30, supports the seat body so that it can move in the front-to-rear direction, and locks the movement of the seat body. As shown in Figures 3 and 4, the vehicle seat S further includes a cover member 60 that extends downward from the rear surface of the seat back 1 and covers the gap between the seat back 1 and the seat cushion 2 in the vertical direction. The cover member 60 is arranged not only to cover the gap between the seat back 1 and the seat cushion 2 in the vertical direction, but also to cover the gap between the seat back 1 and the base member 30 (vehicle body floor) in the vertical direction.

[0021] As shown in FIG. 1, the seat back 1 is a backrest portion that supports the back of the occupant from behind, and is configured by placing a pad material 1a on a back frame 10 shown in FIG. 2, which serves as the skeleton, and covering it with a skin material 1b. The seat cushion 2 is a seating portion that supports the occupant from below, and is configured by placing a pad material 2a on a cushion frame 20 shown in Figure 2, which serves as the skeleton, and covering the pad material 2a with a skin material 2b. The headrest 3 supports the head of the occupant from behind, and is configured by placing a pad material 3a on a pillar (not shown) that serves as a core material, and covering it with a skin material 3b.

[0022] As shown in Figure 2, the back frame 10 is a rectangular frame-shaped body that forms the skeleton of the seat back 1, and left and right connecting brackets 11 are attached to the lower part of the outer surface of the back frame 10 in the seat width direction for connecting it to the base member 30. The connecting bracket 11 is made of a bow-shaped sheet metal member extending in the vertical direction, and the upper end of the connecting bracket 11 is attached to the back frame 10 and the lower end is attached to the base member 30. A reclining device 40 (recliner body 41) that rotatably connects the back frame 10 to the base member 30 is attached to the lower end of the right-side connecting bracket 11. A back rotation shaft 42 that is journaled to the base member 30 in the seat width direction is attached to the lower end of the left-side connecting bracket 11.

[0023] As shown in Figure 2, the cushion frame 20 is a rectangular frame-shaped body that forms the skeleton of the seat cushion 2, and is mainly composed of left and right side frames 21 arranged on the sides in the seat width direction, a plate-shaped pan frame 22 that connects the front parts of each side frame 21, a pipe-shaped rear connecting frame 23 that connects the rear parts of each side frame 21, and a plurality of elastic springs 24 that are hooked onto the pan frame 22 and the rear connecting frame 23, respectively, and extend in a snake-like shape.

[0024] The side frames 21 are made of sheet metal members extending in the front-to-rear direction of the seat, and a connecting link 25 for connecting to the rail device 50 is attached to the front portion of the inner surface of the side frame 21. In addition, a cushion rotation shaft 26 for connecting to the back frame 10 is attached to the rear portion of the inner surface of the side frame 21. The connecting links 25 are members that rotate to store the seat body (seat cushion 2) on the vehicle floor side, and are attached as a pair between the cushion frame 20 and the rail device 50.

[0025] As shown in FIGS. 1 to 5, the base member 30 is a support member that supports the seat body, and connects the back frame 10 (connection bracket 11) and the rail device 50 (upper rail 52) in the vertical direction. In more detail, the base member 30 is arranged on the left and right sides in the seat width direction and comprises an approximately L-shaped side base portion 31 attached to the upper surface of the upper rail 52, a pipe-shaped base connecting portion 32 connecting the left and right side base portions 31, and a base cover 33 covering the side base portions 31 and the base connecting portion 32 from the outside.

[0026] As shown in FIGS. 3 to 5, the base cover 33 is a resin molded product that covers the main body of the base member 30, the reclining device 40, and the rail device 50 from above. The base cover 33 has the function of protecting the reclining device 40 and the rail device 50 from the outside, as well as the function of guiding the movement of the seat body (connecting bracket 11) when the seat body switches from the "used state" to the "storage state." The base cover 33 is disposed on the left and right sides in the seat width direction and has cover side portions 33a that are long in the seat front-rear direction, and a cover rear portion 33b that connects the left and right cover side portions 33a.

[0027] The cover rear portion 33b extends in the seat width direction and connects the rear end portions of the lower portions of the left and right cover side portions 33a, and is positioned rearward of the back pivot shaft 42 and downward of the back pivot shaft 42. The rear cover portion 33b has a plurality of mounting holes 34 (mounting portions) arranged at predetermined intervals in the seat width direction for mounting one end (lower end) of the cover member 60 (second extension member 62).

[0028] As shown in FIG. 2, the reclining device 40 is disposed between the right-side connecting bracket 11 and the right-side base member 30 (base connecting portion 32) in the seat width direction. The reclining device 40 is mainly composed of a reclining body 41 that is driven when rotating the back frame 10, a back rotation shaft 42, a spiral spring 43 that urges the back frame 10 to rotate forward around the back rotation shaft 42, a reclining operation lever 44 shown in FIG. 1 that is operated to release the locked state of the back frame 10, and a reclining cable (not shown) that connects the reclining operation lever 44 and the reclining body 41.

[0029] The reclining body 41 has a known locking mechanism, and the state of the back frame 10 can be switched between a locked state in which it is fixed to the base member 30 and an unlocked state in which it is rotatable relative to the base member 30. The back rotation shaft 42 is supported on the back frame 10 side and the base member 30 side in the seat width direction, and one end of the spiral spring 43 is engaged with the back frame 10 side and the other end is engaged with the base member 30 side. A reclining cable (not shown) is pulled by the operation of the reclining operation lever 44 to switch the seat back 1 from a locked state to an unlocked state.

[0030] In the above configuration, the reclining device 40 locks the seat back 1 in the upright position shown in Figure 3, and when the reclining operation lever 44 is operated, the locked state is released, and the seat back 1 is rotated forward by the force of the spiral spring 43, allowing it to be folded toward the vehicle floor together with the seat cushion 2 (see Figure 4).

[0031] As shown in FIGS. 1 and 2, the rail device 50 is a device that supports the seat body so that it can slide in the front-rear direction of the seat, and is disposed between the seat body and the vehicle floor. The rail device 50 is fixed to the vehicle floor and is mainly composed of left and right lower rails 51 extending in the fore-and-aft direction of the seat, left and right upper rails 52 supported slidably along the lower rails 51, a locking member that locks the upper rails 52 to prevent them from sliding relative to the lower rails 51, a rail operating lever that is operated to release the locked state of the locking member, and a rail cable that connects the locking member and the rail operating lever.

[0032] <Cover material> As shown in Figures 3 to 10, the cover member 60 extends from the rear surface of the seat back 1 and has a first extension member 61 that is deformable in response to the folding operation of the seat back 1, and a second extension member 62 that extends downward from the extension end 61b of the first extension member 61 and covers the gap that occurs between the seat back 1 and the seat cushion 2.

[0033] The first extension member 61 is a flexible (soft) member (e.g., a skin), and as shown in Figures 7 and 10, its base end 61a is attached to the rear surface of the lower part (lower end part) of the seat back, and its extension end 61b is positioned in contact with the rear surface of the seat back 1. The first extension member 61 is configured to deform in response to the folding operation of the seat back 1, and is stored between the seat back 1 and the second extension member when in the "used state" shown in Figure 7, and is exposed to the outside when in the "stored state" shown in Figure 10.

[0034] The second extension member 62 is a plate-shaped member, and specifically, as shown in FIG. 6A, has a flexible skin 63 (first member) and a plate member 64 (second member) fixed to the skin 63. The second extending member 62 extends elongately in the vertical direction, and as shown in Fig. 7, its base end 62a is connected to the base end 61a of the first extending member. Also, as shown in Fig. 6A, its extending end 62b is attached to the rear end portion of the base member 30. When switching from the "used state" shown in Figure 3 to the "storage state" shown in Figure 4, the second extension member 62 moves so as to incline toward the rear of the seat relative to the base member 30 in response to (following) the storage movement of the seat back 1.

[0035] As shown in FIG. 6A, the second extension member 62 has a plurality of mounting holes 65 (mounting portions) formed in the lower portion of the plate member 64, which are spaced apart at predetermined intervals in the seat width direction and are used for mounting to the base member 30. In detail, the second extension member 62 is fixed to the base member 30 by assembling multiple mounting members 66 (mounting bolts) while connecting the mounting holes 34 of the base member 30 to the mounting holes 65 of the second extension member 62. As shown in FIG. 6A, the attachment member 66 is disposed between the cover 63 and the plate member 64, and consideration is given to preventing the attachment member 66 from being exposed from the outside (from behind the seat).

[0036] 6B, as a modified example of the cover member 60, the second extending member 162 may have a folded portion 167 formed on its extending end portion 162b and folded upward from the extending end portion 162b. The folded portion 167 may be attached to the rear end portion of the base member 30. At this time, it is preferable that the mounting hole 165 formed in the folded portion 167 and the mounting hole 34 of the base member 30 are attached by a mounting member 166 .

[0037] <Deformation of the cover member when switching seats> 7 to 10 are diagrams illustrating the state in which the vehicle seat S moves from the "used state" to the "stored state," and also illustrate the state of the cover member 60 at that time. FIG. 7 is a side view of the vehicle seat S in the "used state," and FIG. 10 is a side view of the vehicle seat S in the "stored state."

[0038] In the "use state" shown in Figure 7, the first extension member 61 is stored between the seat back 1 and the second extension member 62, the second extension member 62 extends in the vertical direction, and the upper end of the second extension member 62 abuts against the rear surface of the seat back 1.

[0039] As shown in FIGS. 8 and 9, the first extending member 61 is deformed in accordance with the stowing operation of the seat body, and the second extending member 62 moves so as to tilt toward the rear of the seat. In other words, since the first extension member 61 is attached to the seat back 1, it is pulled into the seat in response to the stowing movement of the seat back 1. In addition, the second extension member 62 is pushed out by the rear end of the seat back 1 and tilts toward the rear of the seat.

[0040] 10, the first extension member 61 is exposed to the outside, and the second extension member 62 is inclined toward the rear of the seat. The upper end of the second extension member 62 abuts against the rear surface of the seat back.

[0041] In the above configuration, in the "use state" shown in FIG. 7, the base end portion 61a of the first extending member 61 is located below the extending end portion 61b. In the "stored state" shown in FIG. 10, the base end portion 61a is located above the extending end portion 61b. This allows the first extension member 61 to be smoothly deformed in accordance with the switching operation of the seat body. In other words, it is possible to prevent the cover member 60 (first extension member 61) from being deformed into an unintended shape when the seat body is switched.

[0042] In addition, in the above configuration, when the vehicle seat S switches between the "used state" and the "storage state", the contact surface of the first extension member 61 that contacts the seat back 1 switches between the front and back surfaces. By doing so, even when the state of the seat body is switched, the first extension member 61 is maintained in contact with the rear surface of the seat back 1, allowing the cover member 60 to be arranged compactly. In addition, the cover member 60 can cover and hide gaps that occur between the seat bodies without impairing the appearance of the seat.

[0043] 7 and 10, when switching from the "storage state" to the "use state," the base end 61a of the first extension member 61 moves to a position in front of the seat relative to its position in the "storage state." More specifically, the base end 61a is located behind the back rotation shaft 42 in the "storage state," and is located in front of the back rotation shaft 42 in the "use state." By doing so, when the seat body is switched from the "storage state" to the "use state", the first extension member 61 can be suitably stored between the seat back 1 and the second extension member 62. In other words, the first extension member 61 can suitably cover and conceal the gap between the seat bodies without being unintentionally exposed.

[0044] In the above configuration, the first extending member 61 is disposed so as to follow the rear surface of the seat back 1 in the "stored state". This improves the appearance of the seat without impairing the appearance of the seat when in the "stored state."

[0045] <Other embodiments> In the above embodiment, the vehicle seat S is moved and stored toward the front side of the seat, but this is not particularly limited, and the vehicle seat S may also be moved and stored toward the rear side of the seat or toward the side of the seat. When the vehicle seat S is moved to be stored toward the rear side of the seat, it is desirable that the vertical positional relationship between the seat back 1 and the seat cushion 2 be reversed when the seat body is stored.

[0046] In the above embodiment, as shown in Figures 1 and 2, the reclining device 40 rotatably connects the seat back 1 to the vehicle floor (base member 30), but this is not particularly limited and the reclining device 40 may also rotatably connect the seat back 1 to the seat cushion 2.

[0047] In the above embodiment, as shown in Figures 1 and 2, the base member 30 is fixed to the vehicle floor via a rail device 50, but this is not particularly limited and may be modified as appropriate, such as being fixed directly to the vehicle floor without the rail device 50. Alternatively, a support bracket (support member) (not shown) fixed onto the vehicle floor may be used instead of the base member 30.

[0048] In the above embodiment, as shown in Figures 3 and 4, the cover member 60 is arranged to cover not only the gap between the seat back 1 and the seat cushion 2 in the vertical direction, but also the gap between the seat back 1 and the base member 30 (vehicle floor) in the vertical direction, but is not particularly limited thereto. For example, the cover member 60 may simply cover the gap between the seat back 1 and the seat cushion 2, or may simply cover the gap between the seat back 1 and the base member 30 (vehicle body floor).

[0049] In the above embodiment, as shown in FIGS. 3 and 7, in the "used state", the first extension member 61 is stored between the seat back 1 and the second extension member 62, but this is not particularly limited. For example, it is sufficient that at least a portion of the first extending member 61 is stored between the seat back 1 and the second extending member 62.

[0050] In the above embodiment, as shown in Figures 3 and 7, when in the "use state", the base end 61a of the first extension member 61 is positioned in a position forward of the seat from the back pivot shaft 42, but this is not particularly limited and does not necessarily have to be positioned in a position forward of the seat from the back pivot shaft 42. For example, when switching from the "storage state" to the "use state," the positional relationship may be such that the first extension member 61 can be retracted into the seat body by the rotational movement of the seat back 1.

[0051] In the above embodiment, a storable vehicle seat used in an automobile was described as a specific example, but it is not limited to this and can also be used as a vehicle seat for trains, buses, etc., as well as for airplanes, ships, etc.
