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 from a normal state. [Background technology]

[0002] 2. Description of the Related Art Vehicle seats are known in the art that are switchable between a "normal state" and a "moving state" in which a seat body is slid from the normal state to a predetermined position in the front-rear direction of the seat. Among these, there is a vehicle seat that is equipped with a locking member that locks the movement of the seat body in the "normal state" and an operating lever that is rotated to release the locked state of the locking member, with the operating lever being attached in a position that is easy for the occupant to operate (see, for example, Patent Document 1).

[0003] The vehicle seat described in Patent Document 1 is a seat in which the seat body can be switched between a normal state and a sliding movement state, and is equipped with a locking mechanism that locks the movement of the seat body, and a slide lever (operating lever) for releasing the locked state of the locking mechanism. The slide lever is rotatably attached via a shaft to a support frame provided on the front surface of the seat cushion. With the above-described configuration, when it is desired to switch the seat body from the normal state to the sliding state, the seated occupant can easily operate the slide lever.

[0004] [Patent Document 1] JP 2009-101821 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, in a vehicle seat such as that in Patent Document 1, there has been a demand for improving the operability of the operating lever by the occupant. More specifically, when an occupant operates an operating lever in the vehicle seat of Patent Document 1, the occupant needs to pull up the operating lever with a finger hooked on the tip of the operating lever. Therefore, when an occupant sitting in the vehicle seat operates the operating lever, the operating lever can be operated relatively smoothly, but when an occupant other than the occupant extends his / her hand to operate the operating lever, there is a risk that the operating lever cannot be operated appropriately.

[0006] Furthermore, in vehicle seats such as those described in Patent Document 1, there was a demand for a vehicle seat that ensures the operability of the operating lever that is operated to switch the state of the seat body, while making the structure of the slide rail device including the operating lever as compact as possible.

[0007] 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 that improves the operability of an operating lever that is operated to switch the state of the seat body. Another object of the present invention is to provide a vehicle seat in which the structure of a switching device including the operating lever is made compact while ensuring the operability of the operating lever. [Means for solving the problem]

[0008] The above problem is solved by the vehicle seat of the present invention, which comprises a seat body having a seat cushion and which is switchable between a normal state and a moving state in which the seat body is moved from the normal state, and which comprises a locking member which is attached to a predetermined position of the vehicle seat and which locks the moving movement of the seat body in the normal state, and an operating lever which is attached to a front portion of the seat cushion via a lever pivot shaft and which is rotated to release the locked state of the locking member, the lever pivot shaft being attached to a base end portion of the operating lever in the extension direction or a portion close to the base end portion, and a hook portion for an occupant to hook a finger on is formed on the outer surface of the operating lever between the lever pivot shaft and a tip portion opposite the base end portion. As described above, a hook portion for a passenger to hook his / her finger is formed between the lever pivot axis and the tip portion opposite the base end portion on the outer surface of the operating lever, thereby realizing a vehicle seat with improved operability of the operating lever. For example, when an occupant operates a control lever, in addition to the conventional method of rotating the control lever with a finger hooked on the tip of the control lever, the occupant can also rotate the control lever by using a hook portion of the control lever. Therefore, the occupant can devise an appropriate method of operating the control lever depending on the situation when operating the control lever. In addition, a simple configuration is adopted in which a hook portion is formed on the outer surface of the operating lever, resulting in a vehicle seat that ensures the operability of the operating lever while compacting the structure of the switching device including the operating lever.

[0009] In this case, the seat includes a lower rail fixed to the vehicle floor, and an upper rail slidably attached along the lower rail and supporting the seat body from below, the moving state being a sliding moving state in which the seat body slides to a predetermined position in the fore-and-aft direction of the seat relative to the vehicle floor, and the locking member is a member that rotates between a locked position that locks the upper rail so that it cannot slide relative to the lower rail, and an unlocked position. With the above configuration, a vehicle seat can be realized that improves the operability of the operating lever in a rail device that includes a lower rail and an upper rail. In addition, when an occupant seated in front of an occupant seated in the seat body reaches out to operate the operating lever, the operability of the operating lever is significantly improved.

[0010] In this case, it is preferable that the catch portion is a catch hole formed so as to penetrate an outer surface of the operating lever. With the above-described configuration, when an occupant operates the operating lever, the occupant can easily hook his / her finger on the hook portion of the operating lever.

[0011] In this case, the hook portion is formed at a position closer to the tip portion than the base end portion in the extension direction of the operating lever, and the length of the hook portion in the extension direction of the operating lever is longer than the length of the tip portion in the extension direction of the operating lever. As described above, since the length of the catch portion is relatively long, the occupant can easily hook his / her finger on the catch portion. In addition, since the catch portion is formed at a position closer to the tip portion than to the base portion in the extension direction of the control lever, for example, a passenger can operate the control lever with his / her fingers hooked on the catch portion and the tip portion of the control lever, thereby improving the operability of the control lever.

[0012] In this case, it is preferable that the tip of the tip portion of the operating lever bends and extends toward the inside of the seat body in the thickness direction of the operating lever, and that the tip is positioned inside the seat body further than the lever pivot axis in the thickness direction of the operating lever. With the above-described configuration, the occupant can easily hook his / her finger on the tip portion of the operating lever, thereby improving the operability of the operating lever.

[0013] In this case, the hook portion is a hook hole, the lever pivot shaft is attached to an upper portion of the operating lever, the hook portion is formed in a lower portion of the operating lever, the operating lever is attached so as to be storable via the lever pivot shaft to a lever storage member provided on the front surface of the seat cushion, the lever storage member has a shape in which the bottom surface of the lever storage member is open, and the hook hole is connected to the open portion of the lever storage member. As described above, the operating lever is attached so as to be storable in the lever storage member provided on the front surface of the seat cushion, and therefore the operating lever can be arranged compactly when not in use. In addition, the lever storage member has an open bottom and the hooking hole is connected to the open portion of the lever storage member, so that it is possible to prevent foreign matter from accumulating on the edge of the hooking hole or inside the lever storage member. In other words, even if a foreign matter gets in through the hooking hole, it is possible to move the foreign matter to the outside from the bottom of the lever storage member.

[0014] In this case, the hook portion is a hook hole, the operating lever is attached to the front surface of the seat cushion, the outer surface of the tip portion of the operating lever is continuous with the outer surface of the operating lever and extends while curving toward the inside of the seat body in the thickness direction of the operating lever, and the tip of the tip portion is preferably positioned inside the seat body further than the hook hole. With the above-described configuration, the occupant can easily hook his / her fingers on the hook portion and the tip portion of the operating lever, which improves the occupant's grip on the operating lever and the operability of the operating lever.

[0015] In this case, a display portion is formed on the outer surface of the operating lever to indicate that the operating lever is a member that is operated to switch the seat body from the normal state to the moving state, and the display portion is preferably positioned on the outer surface of the operating lever between the base end portion to which the lever pivot shaft is attached and the hook portion. As described above, the display portion is disposed on the outer surface of the operating lever between the base end portion and the hook portion, so that the occupant can easily visually confirm the display portion.

[0016] In this case, it is preferable that the length of the display portion in the extending direction of the operating lever is longer than the length of the catch portion in the extending direction of the operating lever. With the above-described configuration, the occupant can visually confirm the display portion more easily.

[0017] In this case, a cable member is provided that connects the operating lever and the locking member and is pulled by the rotational operation of the operating lever to switch the locking member from a locked state to an unlocked state, and a cable attachment portion to which the cable member is attached in the operating lever is preferably positioned between the lever pivot axis and the catch portion in the extension direction of the operating lever. With the above-described configuration, the cable members can be arranged compactly. Effect of the Invention

This embodiment relates to an invention for a vehicle seat having a seat body with a seat cushion, which is switchable between a normal state and a moving state in which the seat body is moved from the normal state, and which is equipped with a locking member that is attached to a predetermined position of the vehicle seat and locks the moving movement of the seat body in the normal state, and an operating lever that is attached to the front part of the seat cushion via a lever pivot shaft and is rotated to release the locked state of the locking member, the lever pivot shaft being attached to the base end portion of the operating lever in the extension direction of the operating lever, and a hook portion for an occupant to hook his or her finger is formed on the outer surface of the operating lever between the lever pivot shaft and the tip portion opposite the base end portion. In addition, the side of the vehicle seat on which an occupant sits relative to the seat back is the front side of the seat.

[0021] The vehicle seat S of the present embodiment is, for example, a rear seat corresponding to the rear seat of a vehicle. Note that the vehicle seat S can also be used as a middle seat in the second row in a vehicle having three rows of seats in the front-rear direction of the vehicle. As shown in Figures 4A and 5A, the vehicle seat S is a seat that 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. In addition, as shown in Figures 6A and 6B, the vehicle seat S is a seat that can be arranged in two different configurations: an "used state" in which an occupant can be seated, and a "stored state" in which the seat body is stored in the vehicle floor. Specifically, when the occupant pulls the reclining operation lever 44 at the upper end of the seat body, the vehicle seat S is switched from the "used state" shown in Fig. 6A to the "stored state" shown in Fig. 6B in which the seat body is folded forward and stored on the vehicle floor. Then, the occupant manually raises the seat body upward from the stored state to return to the "used state".

[0022] 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 support base 30 that supports the seat body from below, and a reclining device 40 that rotatably connects the seat back 1 to the support base 30 and locks the rotational movement of the seat back 1. The vehicle seat S further includes a rail device 50 that is attached between the vehicle floor and the support base 30, supports the seat body so that it can move in the front-rear direction, and locks the movement of the seat body.

[0023] As shown in FIG. 1, the seat back 1 is a backrest portion that supports the back of an occupant from behind, and is configured by placing a pad member 1a on a back frame 10 shown in FIG. 2, which serves as the skeleton, and covering it with a skin 1b. The seat cushion 2 is a seating portion that supports an occupant from below, and is configured by placing a pad member 2a on a cushion frame 20 shown in FIG. 2, which serves as a skeleton, and covering the pad member 2a with a skin 2b. Incidentally, a mounting recess 2c for mounting an operating lever 60 is formed on the right side in the seat width direction on the front surface of the seat cushion 2. The headrest 3 supports the head of an occupant from behind, and is configured by placing a pad member 3a on a pillar (not shown) that serves as a core material, and covering it with a skin 3b.

[0024] As shown in FIG. 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 to the support base 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 support base 30. A reclining device 40 (reclining body 41) that rotatably connects the back frame 10 to the support base 30 is attached to the lower end of the right-side connecting bracket 11, and a back rotation shaft 42 that is journalled to the support base 30 in the seat width direction is attached to the lower end of the left-side connecting bracket 11.

[0025] As shown in FIG. 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 number 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.

[0026] The side frame 21 is made of a sheet metal member extending in the front-rear direction of the seat, and a connecting link 25 for connecting to the rail device 50 is attached to the front part 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 part of the inner surface of the side frame 21. The connecting link 25 is a member that rotates to store the seat body (seat cushion 2) on the vehicle floor side, and is attached as a pair between the cushion frame 20 and the rail device 50. An attachment hole 22a for attaching the operating lever 60 and the lever storage member 70 shown in FIG. 1 is formed on the right side of the front surface of the pan frame 22 in the seat width direction.

[0027] As shown in FIG. 2, the support base 30 is a base 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 detail, the support base 30 is arranged on the side 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, and a pipe-shaped base connecting portion 32 connecting the left and right side base portions 31.

[0028] As shown in FIG. 2, the reclining device 40 is disposed between the right-side connecting bracket 11 and the right-side support base 30 (base connecting portion 32) in the seat width direction. The reclining device 40 is mainly composed of a reclining main body 41 that is driven to rotate 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 Figure 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 main 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 support base 30 and an unlocked state in which it is rotatable relative to the support base 30. The back rotation shaft 42 is supported on the back frame 10 side and the support base 30 side in the seat width direction, and one end of the spiral spring 43 is anchored to the back frame 10 side and the other end is anchored to the support base 30 side. In addition, 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 back frame 10 in the upright position shown in Figure 6A, and when the reclining operation lever 44 is operated, the locked state is released, and the back frame 10 is rotated forward by the force of the spiral spring 43, so that it can be folded toward the vehicle floor together with the cushion frame 20 (see Figure 6B).

[0031] As shown in Figs. 1 to 5C, the rail device 50 is a device that supports the seat body so that the seat body 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 mainly composed of left and right lower rails 51 that are fixed to the vehicle floor and extend in the fore-and-aft direction of the seat, left and right upper rails 52 that are supported slidably along the lower rails 51, a locking member 53 that locks the upper rails 52 so that they cannot slide relative to the lower rails 51, an operating lever 60 that is operated to release the locked state of the locking member 53, a lever pivot shaft 54 ​​that serves as the pivot shaft of the operating lever 60, and a rail cable 55 that connects the locking member 53 and the operating lever 60.

[0032] As shown in Figures 4C and 5C, the locking member 53 is disposed between the left and right upper rails 52, and is a member that rotates between a locked position in which the upper rails 52 are locked so as not to slide relative to the lower rails 51, and an unlocked position. In detail, the locking member 53 is mainly composed of a locking body 53a and a pivoting lever 53c that connects the locking body 53a and the rail cable 55 and pivots about a pivot axis 53b as the rail cable 55 is pulled. The lock body 53a and the rotating lever 53c are biased to the lock position by a spring (not shown).

[0033] The lock body 53a is attached to the inner surface of the left upper rail 52, and operates (rotates) to disengage an engagement groove (not shown) provided in the upper rail 52 from an engagement claw (not shown) provided in the lower rail 51 in conjunction with the rotational movement of the pivot lever 53c, thereby releasing the locked state of the upper rail 52. The rotating lever 53c is a rotating member that is long in the vertical direction and is attached via a rotating shaft 53b to the inner surface of the upper rail 52. The rotating lever 53c functions as a transmission member that transmits the pulling action of the rail cable 55 to the lock main body 53a.

[0034] As shown in Figures 4A to 4C, the rail cable 55 has one end 55a attached to the operating lever 60, a folded-back portion (not shown) that extends from the one end 55a to the rear of the seat and is folded back, and the other end 55b that extends from the folded-back portion to the front of the seat and is attached to the locking member 53 (rotating lever 53c). The rail cable 55 is pulled by the rotational movement of the operating lever 60 and acts to switch the locking member 53 from the locked position to the unlocked position.

[0035] As shown in Figures 1, 3A, 3B, and 4B, the operating lever 60 is a lever that is rotated to release the locked state of the rail device 50, and is attached to the front portion of the seat cushion 2 in the vehicle seat S. More specifically, the operating lever 60 is attached to the lever storage member 70 via a lever rotation shaft 54 ​​so as to be rotatable relative to the lever storage member 70 while being stored in the lever storage member 70 provided on the front surface of the seat cushion 2 . The operating lever 60 is a lever that is long in the vertical direction, with its upper end portion corresponding to the "base end portion" and its lower end portion corresponding to the "tip portion."

[0036] The operating lever 60 is mainly composed of a lever front portion 60a which forms the outer surface of the operating lever 60 and extends longitudinally in the vertical direction, a lever upper portion 60b which extends from the upper end of the lever front portion 60a toward the rear of the seat, left and right lever side portions 60c which extend rear of the seat from both ends of the lever front portion 60a in the seat width direction and are connected to the lever front portion 60a and the lever upper portion 60b, and a lever central portion 60d which has an inverted U-shaped cross section and protrudes toward the rear of the seat from the central portion of the lever front portion 60a in the seat width direction.

[0037] An indicator 61 is formed on the outer surface of the lever front portion 60a, which indicates that the operating lever 60 is a member that is operated to switch the seat body from the "normal state" to the "sliding state". Further, on the outer surface of the lever front portion 60a, below the display portion 61, a hook portion 62 is formed so as to penetrate the lever front portion 60a and is used by an occupant to hook his / her finger. The display portion 61 and the catch portion 62 are arranged vertically on the outer surface of the operating lever 60 .

[0038] A lever rotation shaft 54 ​​that is long in the seat width direction is supported at upper end portions (base end portions) of the left and right lever side portions 60c. The lever rotation shaft 54 ​​is supported by the operating lever 60 (lever side portions 60c) and the lever storage member 70 in the seat width direction. A cable attachment portion 63 for attaching the rail cable 55 (one end portion 55a) is formed between the lever rotation shaft 54 ​​and the catch portion 62 in the vertical direction on the outer surface of the lever central portion 60d.

[0039] As shown in FIG. 3A, the display unit 61 illustrates that the operating lever 60 is an operating member for sliding the seat body, and the illustration is formed by a concave-convex shape on the front surface of the operating lever 60. The vertical length of the display portion 61 is longer than the vertical length of the hook portion 62 . The catch portion 62 is a generally rectangular catch hole, and is formed at a position closer to the lower end portion (tip portion) of the operating lever 60 than to the upper end portion (base end portion). The vertical length of the hook portion 62 is longer than the vertical length of the lower end portion of the operating lever 60. In addition, the width direction length of the hook portion 62 is longer than the width direction length of the display unit 61.

[0040] In the above configuration, as shown in FIG. 3A, since the operating lever 60 has the catch portion 62, the occupant can easily rotate the operating lever 60 by utilizing the catch portion 62. More specifically, the occupant can easily grip the operating lever 60 by hooking his / her fingers on the catch portion 62 (the edge portion of the catch portion 62) and the lower end portion of the operating lever 60.

[0041] As shown in FIG. 7A, a hook recess 64 may be formed separately at the lower end portion of the operating lever 60 (the edge portion of the hook portion 62) to facilitate hooking of the passenger's finger. The latch recess 64 is formed on the upper surface of the lower end portion of the operating lever 60, and is preferably formed in two places at a predetermined interval in the seat width direction. Also, it is preferable that the latch recess 64 has a smoothly curved surface. Alternatively, as shown in FIG. 7B, a hooking uneven portion 65 may be separately formed on the lower end portion of the operating lever 60 in order to make it easier for the passenger to hook the finger thereon. The latch uneven portion 65 is a fine uneven portion formed by embossing the entire upper surface of the lower end portion of the operating lever 60 .

[0042] In the above configuration, the lower end of the operating lever 60 is bent and extends toward the inside of the seat cushion 2 in the thickness direction of the operating lever 60, as shown in FIG. 4B. More specifically, the lower end of the operating lever 60 is disposed inside the seat cushion 2 with respect to the lever rotation shaft 54 ​​in the thickness direction of the operating lever 60. Therefore, the passenger can easily hook his / her finger on the lower end portion of the operating lever 60. This improves the operability of the operating lever 60.

[0043] In the above configuration, as shown in FIG. 4B, the outer surface of the lower end portion of the operating lever 60 is formed continuously with the outer surface of the operating lever 60 and extends while curving toward the inside of the seat cushion 2 in the thickness direction of the operating lever 60. In addition, the lower end of the operating lever 60 is disposed inside the seat cushion 2 with respect to the catch portion 62 . Therefore, the occupant can easily hook his / her fingers on the catch portion 62 and the lower end portion of the operating lever 60. This improves the occupant's grip on the operating lever 60, improving the operability of the operating lever 60.

[0044] The lever storage member 70 is a storage plate that rotatably supports the operating lever 60, as shown in Figs. 1, 3A, 3B, and 4B, and is attached by being fitted into the mounting recess 2c of the seat cushion 2. The lever housing member 70 has a box shape with an open bottom. In detail, the lever storage member 70 is mainly composed of left and right side portions 70a arranged at a predetermined interval in the seat width direction, an upper portion 70b connecting the upper ends of the left and right side portions 70a, a rear portion 70c connecting the rear ends of the left and right side portions 70a, left and right side flange portions 70d bent from the front ends of the left and right side portions 70a and protruding outward in the seat width direction, and an upper flange portion 70e bent from the front end of the upper portion 70b and protruding upward.

[0045] A lever rotation shaft 54 ​​that is long in the seat width direction is supported at the upper end portions of the left and right side portions 70a. The rear portion 70c is formed with a cable attachment portion 71 for attaching the rail cable 55 (one end portion 55a) and a frame attachment portion 72 for attachment to the cushion frame 20 (pan frame 22). The cable attachment portion 71 is disposed at a position above the frame attachment portion 72 .

[0046] In the above configuration, as shown in FIG. 4A, the catch portion 62 of the operating lever 60 and an open portion 73 located at the lower end of the lever housing member 70 communicate with each other. This makes it possible to prevent foreign matter from accumulating on the edge of the catch portion 62 or inside the lever storage member 70. In other words, even if a foreign matter enters through the catch portion 62, the foreign matter can be moved to the outside from the bottom surface of the lever storage member 70.

[0047] In the above configuration, as shown in Figures 1 and 4A, when the operating lever 60 is in the locked position, the front surface of the seat cushion 2, the front surface of the operating lever 60, and the front surface of the lever storage member 70 are approximately flush with each other. Therefore, the operating lever 60 can be compactly arranged in the front portion of the seat cushion 2 without impairing the design of the vehicle seat S.

[0048] Next, the vehicle seat unit U will be described with reference to FIG. The vehicle seat unit U is configured by arranging a plurality of vehicle seats S in the seat width direction. In the vehicle seat unit U, operation levers 60 (60A, 60B) provided on adjacent vehicle seats S are disposed at positions on the center side of the vehicle seat unit U in the seat width direction. Therefore, for example, an occupant can operate each of the operating levers 60 from a position forward of the vehicle seat S, and can switch the states of the adjacent seat bodies together.

[0049] <Second embodiment of vehicle seat> Next, a second embodiment of the vehicle seat will be described with reference to Figs. It should be noted that the description overlapping with the above-mentioned vehicle seat S will be omitted. The vehicle seat S2 of the second embodiment differs from the vehicle seat S mainly in that it is provided with an ottoman device 180, and the configuration of the operation lever 160 is also different.

[0050] The vehicle seat S2 can be arranged in three different configurations: an "used state" in which an occupant can be seated; a "stored state" in which the seat body is stored in the vehicle floor; and a "tip-up state" in which the seat body is flipped up. As shown in FIG. 14, a recessed storage floor is provided at a seat front side of the vehicle seat S2, the storage floor being positioned lower than the vehicle body floor.

[0051] As shown in FIGS. 8 and 9, the ottoman device 180 is attached to the front end portion of the seat cushion 102, and is disposed in the center portion of the seat cushion 102 in the seat width direction. The ottoman device 180 is mainly composed of an ottoman rotation shaft 181 that extends in the seat width direction and is journalled at the front end portion of the seat cushion 102, a leg support member 182 that rotates around the ottoman rotation shaft 181 relative to the seat cushion 102, and a movable unit (not shown) for moving the leg support member 182.

[0052] The leg support member 182 is rotatable between a "storage position" shown in FIG. 8 in which it is stored inside the seat cushion 102, a "deployed position" shown in FIG. 9 in which it is deployed from the storage position forward of the seat cushion 102, and a "tip-up position" shown in FIG. 10 in which it stands up (vertically) above the "deployed position." The leg support member 182 is mainly composed of a support side end portion 182a supported on the front end portion of the seat cushion 2, and a deployment side end portion 182b formed to be wider in the seat width direction than the support side end portion 182a.

[0053] As shown in FIG. 10, a plurality of hook-shaped locking members 183 are attached to the front end portion of the bottom surface of the leg support member 182 (the deployment side end portion 182b) at predetermined intervals in the seat width direction. The locking members 183 are umbrella-shaped hook members, and are disposed at the center of the leg support member 182 in the seat width direction and at both ends in the seat width direction. As shown in FIG. 11, a plurality of hook-shaped locking members 184 are attached to the upper portion of the rear surface of the seat back 101 at predetermined intervals in the seat width direction.

[0054] With the above-described configuration, it is possible to realize a vehicle seat S2 in which the seat can be arranged in a compact manner and the ottoman device 180 is arranged in a compact manner. 10, when luggage with a handle is placed on the seat cushion 102, the handle of the luggage can be locked with the locking member 183. This makes it possible to prevent the luggage from moving. Furthermore, with the above-described configuration, by moving leg support member 182 to the "tip-up position", for example, when luggage with a handle is placed on seat cushion 102, the mesh-like net can be engaged with engaging members 183 and 184 so as to cover the luggage from above. This makes it possible to easily secure the luggage.

[0055] The operating lever 160 is a lever that is rotated to release the locked state of the rail device 150, as shown in Figs. 8, 12A, and 12B. The operating lever 160 has a generally box-like shape with an open bottom. In detail, the operating lever 160 is mainly composed of a lever front portion 160a which forms its outer surface and extends longitudinally in the vertical direction, a lever upper portion 160b which extends from the upper part of the lever front portion 160a toward the rear of the seat, left and right lever side portions 160c which extend rearward from both ends of the lever front portion 160a in the seat width direction and are connected to the lever front portion 160a and the lever upper portion 160b, and a lever rear portion 160d which connects the rear ends of the left and right lever side portions 160c.

[0056] A display portion 161 and a hook portion 162 are formed on the outer surface of the lever front portion 160a. The vertical length of the hook portion 162 is longer than the vertical length of the display portion 161. Therefore, the hole of the hook portion 162 can be formed large. A lever rotation shaft 154 that is long in the seat width direction is supported at the upper end portions of the left and right lever side portions 160c. The lever rotation shaft 154 is supported by the operating lever 160 and the lever storage member 170 in the seat width direction. A cable attachment portion for attaching a rail cable (not shown) is formed on the inner surface of the lever rear portion 160d.

[0057] Even with the above configuration, it becomes easier for the passenger to grip the operating lever 160 with his / her fingers, and the operability of the rail device 150 can be improved. In particular, when the vehicle seat S2 is a rear seat (middle seat), an occupant seated in the front seat can reach out and hook his / her finger on the catch portion 162, and can operate the operation lever 160 in that state. Specifically, the occupant can easily move the vehicle seat S2 forward by pulling the vehicle seat S2 forward with his / her finger hooked on the operation lever 160. Naturally, the vehicle seat S2 can also be moved backward by pushing it rearward.

[0058] Next, the vehicle seat unit U2 will be described with reference to FIG. The vehicle seat unit U2 is configured by arranging a plurality of vehicle seats S in the seat width direction. In the vehicle seat unit U, operation levers 160 (160A, 160B) provided on adjacent vehicle seats S are disposed at positions on the center side of the vehicle seat unit U in the seat width direction. At this time, the recliner operating lever 144, the armrest 4, and the operating lever 160 are arranged so as to overlap at least partially in the seat width direction.

[0059] In the above configuration, as shown in FIG. 13, a floor abutment portion 190 is attached to the front end portion of the bottom surface of the seat cushion 102, which abuts against the vehicle floor when the seat body is stored in the vehicle floor in the “stored state”. The floor contact portion 190 is made of an elastic resin material and is attached to both end portions in the seat width direction of the seat cushion 102. The floor contact portion 190 and the operating lever 160 are disposed at the same position in the seat width direction.
