Abstract

The objective is to reduce the installation space required for multiple operating components. [Solution] The operating mechanism comprises a base member 70, a first operating member 80, and a second operating member 90. The first operating member 80 is a member that operates the first movable member. The first operating member 80 is rotatable around the first pivot axis X11 relative to the base member 70. The second operating member 90 is a member that operates the second movable member. The second operating member 90 is positioned overlapping the first operating member 80 and is rotatable around the second pivot axis X12 relative to the first operating member 80. When the first operating member 80 is operated, the second operating member 90 rotates together with the first operating member 80, causing the first movable member and the second movable member to move. When the second operating member 90 is operated, the second operating member 90 rotates relative to the first operating member 80, causing the second movable member to move while the first movable member remains stationary.

Description

[Technical Field]

[0001] The present invention relates to an operating mechanism provided with two operating members. [Background Art]

[0002] Conventionally, an operating mechanism for unlocking a reclining mechanism of a vehicle seat is known (see Patent Document 1). The operating mechanism in this technology is a mechanism for operating an unlocking member that unlocks the reclining mechanism, and includes an operating lever operated by a user, and a wire that connects the operating lever and the unlocking member. [Prior Art Literature] [Patent Literature]

[0003] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2002-209659 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] Incidentally, a vehicle seat may be provided with a plurality of members to be operated by a user, like the aforementioned unlocking member. In this case, it is necessary to provide a plurality of operating levers on the vehicle seat, and it is desired that the installation space for the plurality of operating levers does not become large.

[0005] Therefore, an object of the present invention is to reduce the installation space for a plurality of operating members. [Means for Solving the Problem]

[0006] In order to solve the aforementioned problem, an operating mechanism according to the present invention includes a base member, a first operating member, and a second operating member. The first operating member is a member that operates a first movable member. The first operating member is rotatable about a first rotation shaft relative to the base member. The second operating member is a member that operates the second movable member. The second operating member is positioned overlapping the first operating member and is rotatable relative to the first operating member about the second pivot axis. When the first operating member is operated, the second operating member rotates together with the first operating member, causing the first movable member and the second movable member to move. When the second operating member is operated, the second operating member rotates relative to the first operating member, causing the second movable member to move while the first movable member remains stationary.

[0007] With this configuration, the second operating member is positioned overlapping the first operating member, which reduces the installation space required for multiple operating members compared to a configuration where the first and second operating members are not positioned overlapping. Furthermore, operating the first operating member causes both the first and second movable members to move, improving operability.

[0008] Furthermore, the first operating member may extend from the first pivot axis in one direction in the first direction, the second pivot axis may be located away from the first pivot axis in one direction in the first direction, and the second operating member may be rotatably supported by the first operating member about the second pivot axis and extend from the second pivot axis toward the first pivot axis.

[0009] With this configuration, the rotation direction of the first operating member and the rotation direction of the second operating member are opposite, which helps to prevent the user from accidentally operating the wrong operating member.

[0010] Furthermore, the first operating member may have a first mounting portion to which a first connecting member connecting the first operating member and the first movable member is attached, and the second operating member may have a second mounting portion to which a second connecting member connecting the second operating member and the second movable member is attached. In this case, the first mounting portion and the second mounting portion are located between the first pivot shaft and the second pivot shaft in the first direction, and in the first direction, the distance from the first pivot shaft to the first mounting portion may be greater than the distance from the first mounting portion to the second pivot shaft, and in the first direction, the distance from the first pivot shaft to the second mounting portion may be greater than the distance from the second mounting portion to the second pivot shaft.

[0011] Furthermore, the base member may have a cover portion that covers the connecting portion between the first operating member and the second operating member from both sides in a second direction along the first rotation axis.

[0012] With this configuration, the cover prevents dust from entering the connection between the first operating member and the second operating member.

[0013] Furthermore, the base member has a main body that supports the first operating member, and the cover portion may protrude from both ends of the main body in the second direction.

[0014] Furthermore, the first operating member may have a first gripping portion operated by the user, and the second operating member may have a second gripping portion operated by the user, which overlaps with the first gripping portion in a third direction. In this case, the second pivot axis may be located in one of the third directions relative to the first pivot axis, and the second gripping portion may be located in one of the third directions relative to the first pivot axis.

[0015] With this configuration, for example, compared to a configuration where the first pivot axis is located in one of the third directions of the second gripping part, it is possible to suppress the first operating member from protruding in one of the third directions.

[0016] Furthermore, the first operating member may have a first gripping portion operated by the user, and the second operating member may have a second gripping portion operated by the user, which overlaps with the first gripping portion in a third direction. In this case, the first gripping portion may have a hole, and the second operating member may have a projection that protrudes from the second gripping portion in a third direction and enters the hole.

[0017] With this configuration, the protrusion of the second gripping part fits into the hole of the first gripping part, thereby suppressing misalignment of the second gripping part relative to the first gripping part.

[0018] Furthermore, the first operating member may be the member operated when moving the sheet in a first operation, and the second operating member may be the member operated when moving the sheet in a second operation different from the first operation. In this case, the outer surface of the second operating member may display first information indicating that the sheet is being moved in a first operation, and second information indicating that the sheet is being moved in a second operation, with the first information located at one end of the outer surface on the second pivot axis side, and the second information located at the other end of the outer surface opposite to the one end.

[0019] With this configuration, the first information is located at one end of the outer surface of the second operating member on the side of the second rotation axis, and the second information is located at the other end opposite to the outer surface. As a result, each piece of information is displayed on the side of the two operating members where the user's fingers are placed, thus suppressing accidental operation.

[0020] The method for manufacturing the aforementioned operating mechanism comprises the following steps. A step of preparing the base member, the first operating member, and the second operating member. A step of attaching the first operating member to the base member. A step of attaching the second operating member to the first operating member by overlapping them.

[0021] The first operating member extends from the first pivot axis in one of the first directions, the second pivot axis is located away from the first pivot axis in one of the first directions, and the second operating member may be rotatably supported by the first operating member about the second pivot axis and extend from the second pivot axis toward the first pivot axis. When manufacturing an operating mechanism configured in this manner, the end of the first operating member on the first pivot axis side is attached to the base member. Furthermore, the end of the second operating member on the second pivot axis side is attached to the portion of the first operating member that is away from the first pivot axis.

[0022] Said first operating member has a first mounting portion to which a first connecting member that connects said first operating member and said first movable member is attached, said second operating member has a second mounting portion to which a second connecting member that connects said second operating member and said second movable member is attached, said first mounting portion and said second mounting portion are located between said first rotation shaft and said second rotation shaft in a first direction, in said first direction, a distance from said first rotation shaft to said first mounting portion may be greater than a distance from said first mounting portion to said second rotation shaft, and in said first direction, a distance from said first rotation shaft to said second mounting portion may be greater than a distance from said second mounting portion to said second rotation shaft. When manufacturing the operating mechanism configured as described above, when attaching said first operating member to said base member, the first mounting portion is arranged between said first rotation shaft and said second rotation shaft in said first direction. When attaching said second operating member to said first operating member, the second mounting portion is arranged between said first rotation shaft and said second rotation shaft in said first direction.

[0023] Said base member may have cover portions that cover a connecting portion between said first operating member and said second operating member from both sides in a second direction along said first rotation shaft. When manufacturing the operating mechanism configured as described above, the connecting portion between said first operating member and said second operating member is placed inside said cover portions.

[0024] Said base member has a main body portion that supports said first operating member, and said cover portions may protrude from both ends of said main body portion in said second direction. When manufacturing the operating mechanism configured as described above, the connecting portion between said first operating member and said second operating member is placed between two of said cover portions protruding from both ends of said main body portion in said second direction.

[0025] The first operating member has a first gripping portion operated by the user, and the second operating member has a second gripping portion operated by the user, the second gripping portion overlapping the first gripping portion in a third direction, the second pivot axis may be located in one of the third directions relative to the first pivot axis, and the second gripping portion may be located in one of the third directions relative to the first pivot axis. When manufacturing an operating mechanism configured in this way, the second operating member is attached to the first operating member by overlapping the second gripping portion with the first gripping portion from one side in the third direction.

[0026] The first operating member has a first gripping portion operated by the user, and the second operating member has a second gripping portion operated by the user, which has a second gripping portion that overlaps with the first gripping portion in a third direction, the first gripping portion has a hole, and the second operating member has a projection that protrudes from the second gripping portion in the third direction, which may have a projection that enters the hole. When manufacturing an operating mechanism configured in this manner, when attaching the second operating member to the first operating member, the protruding portion of the second operating member is inserted into the hole in the first operating member.

[0027] The first operating member is operated when the sheet is moved in a first operation, and the second operating member is operated when the sheet is moved in a second operation different from the first operation, and the outer surface of the second operating member displays first information indicating that the sheet is moved in a first operation and second information indicating that the sheet is moved in a second operation, the first information may be located at one end of the outer surface on the second pivot axis side, and the second information may be located at the other end of the outer surface opposite to the one end. [Effects of the Invention]

[0028] According to the present invention, since the second operating member is positioned overlapping the first operating member, the installation space required for the multiple operating members can be reduced compared to a configuration in which, for example, the first and second operating members are positioned without overlapping. Furthermore, since both the first and second movable members move when the first operating member is operated, operability can be improved.

[0029] Furthermore, by configuring the first operating member and the second operating member to rotate in opposite directions, it is possible to prevent the user from accidentally operating the wrong operating member.

[0030] Furthermore, by having a cover portion in the base member, dust can be prevented from entering the connection portion between the first operating member and the second operating member.

[0031] Furthermore, by configuring the second pivot shaft and the second gripping portion to be located in one of the third directions relative to the first pivot shaft, it is possible to suppress the first operating member from protruding in one of the third directions, compared to, for example, a configuration in which the first pivot shaft is located in one of the third directions relative to the second gripping portion.

[0032] Furthermore, by configuring the protrusion of the second gripping part to fit into the hole of the first gripping part, misalignment of the second gripping part relative to the first gripping part can be suppressed.

[0033] Furthermore, by arranging the first information to be located at one end of the outer surface of the second operating member on the side of the second rotation axis, and the second information to be located at the other end opposite to the outer surface, the information is displayed on the side of the two operating members where the user's finger is placed, thereby suppressing accidental operation.

[Figure 5] This diagram shows the relationship between the operating mechanism and the operation of the seat. Figure (a) shows the state in which each operating member is not operated, Figure (b) shows the state in which the second operating member is operated, and Figure (c) shows the state in which the first operating member is operated. [Modes for carrying out the invention]

[0035] The following describes an embodiment of a vehicle seat with reference to the drawings. As shown in Figure 1, the vehicle seat S is an example of a vehicle seat, for example, the second row seat of a vehicle. The vehicle seat S has a seat body S0, a reclining mechanism R, left and right base frames S4, left and right sliding mechanisms S5, and an operating mechanism LM. In this embodiment, the front-to-back, left-to-right, and up-and-down directions are based on the occupant sitting in the seat. In this embodiment, the front-to-back direction corresponds to the first direction, the left-to-right direction corresponds to the second direction, and the up-and-down direction corresponds to the third direction.

[0036] The seat body S0 comprises a seat cushion S1, a seat back S2, and a headrest S3. The seat back S2 is rotatable relative to the seat cushion S1.

[0037] The reclining mechanism R can be switched between a locked state, which locks the rotation of the seat back S2, and an unlocked state, which releases the lock on the rotation of the seat back S2. The reclining mechanism R includes a reclining spring R1 and a reclining lock release member 30 shown in Figure 1(c). The reclining spring R1 biases the seat back S2 in a direction that tilts it forward.

[0038] The reclining lock release member 30 is a component for switching the reclining mechanism R from a locked state to an unlocked state. The reclining lock release member 30 is rotatable between the locked position shown by the solid line and the unlocked position shown by the dashed line in Figure 1(c). The reclining lock release member 30 is biased to the locked position by a locking spring within the reclining mechanism R.

[0039] The base frame S4 ​​is a member that supports the seat body S0. The base frame S4 ​​is located below the seat body S0 and on both sides of the seat body S0. The left and right base frames S4 are connected by connecting members (not shown) and are movable as a single unit.

[0040] The sliding mechanism S5 is a mechanism that supports the seat body S0 so that it can slide in the front-to-back direction. The sliding mechanism S5 is located below the left and right base frames S4. The sliding mechanism S5 includes an upper rail S51 and a lower rail S52.

[0041] The base frame S4 ​​is fixed to the upper rail S51. The lower rail S52 supports the upper rail S51 so that it can move in the longitudinal direction. The lower rail S52 is fixed to the vehicle floor F (see Figure 2(a)).

[0042] A slide lock mechanism 10 is provided on the base frame S4 ​​or the upper rail S51. The slide lock mechanism 10 is a mechanism for prohibiting or allowing the seat body S0 to slide in the front-rear direction.

[0043] As shown in Figure 1(b), the slide lock mechanism 10 includes a slide lock member 11. The slide lock member 11 is a member for locking or unlocking the sliding movement of the seat body S0. The slide lock member 11 is rotatably supported on the base frame S4 ​​or the upper rail S51, and its rotatable hook-shaped tip 11A is capable of engaging with a hole Hs formed in the lower rail S52. The slide lock member 11 is rotatable between a slide lock position (shown by a solid line) that locks the sliding movement of the seat body S0 and a slide release position (shown by a dashed line) that unlocks the sliding movement. The slide lock member 11 is biased from the slide release position toward the slide lock position by a spring (not shown).

[0044] As shown in Figure 2, the operating mechanism LM comprises a base member 70, a first operating member 80, and a second operating member 90. The base member 70 has a main body portion 71 and left and right side wall portions 72.

[0045] The main body portion 71 is a plate-shaped part that supports the first operating member 80 from below. The main body portion 71 has a hole 71A that penetrates vertically.

[0046] The two side wall portions 72 are each connected to the left and right ends of the main body portion 71. The side wall portion 72 has a cover portion 72A that protrudes upward from the left and right ends of the main body portion 71 and an extension portion 72B that extends rearward from the main body portion 71.

[0047] The cover portion 72A covers the connecting portion between the first operating member 80 and the second operating member 90 from both sides in the left-right direction (see Figure 3(a)). The extension portion 72B has a hole 72C that supports the first connecting shaft SF1.

[0048] The first operating member 80 is a member that operates the reclining lock release member 30, which is an example of the first movable member shown in Figure 1(c). The first operating member 80 is connected to the reclining lock release member 30 by a wire W1, which is an example of the first connecting member. The first operating member 80 is operated when moving the vehicle seat S in a reclining operation, which is an example of the first operation.

[0049] Returning to Figure 2, the first operating member 80 has a first gripping portion 81 operated by the user, a supported portion 82 rotatably supported by the base member 70, a support portion 83 that rotatably supports the second operating member 90, and a protruding portion 84.

[0050] The first gripping portion 81 is a plate-shaped part having a surface that intersects with the vertical direction. The first gripping portion 81 has a hole 81A that penetrates vertically.

[0051] The supported portion 82 protrudes downward from the rear end of the first gripping portion 81. The supported portion 82 has a hole 82A through which the first connecting shaft SF1 passes. The supported portion 82 is rotatably connected to the left and right side walls 72 of the base member 70 via the first connecting shaft SF1.

[0052] As a result, as shown in Figures 3(b) and 4(c), the first operating member 80 is rotatable in a clockwise direction relative to the base member 70 about the first pivot axis X11 which is aligned in the left-right direction. The first gripping portion 81 of the first operating member 80 extends forward from the first pivot axis X11.

[0053] Returning to Figure 2, the support portions 83 are provided on both the left and right sides of the front end of the first gripping portion 81. The support portions 83 protrude upward from the first gripping portion 81. The support portions 83 have holes 83A that support the second connecting shaft SF2.

[0054] The protruding portion 84 protrudes downward from the first gripping portion 81. The protruding portion 84 enters the hole 71A of the base member 70 and protrudes below the main body portion 71 of the base member 70. As shown in Figure 4(a), the protruding portion 84 has a first mounting hole 84A as an example of a first mounting portion. A wire W1 is attached to the first mounting hole 84A.

[0055] The second operating member 90 is a member that operates the slide lock member 11, which is an example of the second movable member shown in Figure 1(b). The second operating member 90 is connected to the slide lock member 11 by a wire W2, which is an example of the second connecting member. The second operating member 90 is operated when the vehicle seat S is moved by a sliding motion, which is an example of the second motion.

[0056] As shown in Figures 2 and 4, the second operating member 90 is positioned above and below the first operating member 80. The second operating member 90 has a second gripping portion 91 operated by the user, a supported portion 92 that is rotatably supported by the first operating member 80, and a protruding portion 93.

[0057] The second gripping portion 91 is a plate-shaped part having a surface that intersects with the vertical direction. The second gripping portion 91 overlaps with the first gripping portion 81 in the vertical direction. In this embodiment, as shown in Figure 3(c), when viewed from the vertical direction, the entire second gripping portion 91 is located inside the outer edge of the first operating member 80. The upper surface 91A, which is the outer surface of the second gripping portion 91, displays the first information G1 and the second information G2.

[0058] The first information G1 indicates that the vehicle seat S is moved in a reclining motion. The second information G2 indicates that the vehicle seat S is moved in a sliding motion. In this embodiment, the first information G1 and the second information G2 are represented by words such as "reclining" and "slide". The first and second information may also be represented by information such as diagrams showing the movement of the vehicle seat S.

[0059] The first information G1 is located at the front end of the upper surface 91A (one end on the side of the second rotation axis X12, which will be described later). More specifically, the first information G1 is located on the free end side of the first operating member 80, that is, on the end side of the first operating member 80 where the user's finger will grip.

[0060] The second information G2 is located at the rear end of the upper surface 91A. More specifically, the second information G2 is located at the free end of the second operating member 90, that is, the end of the second operating member 90 that the user's finger grips.

[0061] Returning to Figure 2, the supported portion 92 protrudes downward from the front end of the second gripping portion 91. The supported portion 92 has a hole 92A through which the second connecting shaft SF2 passes. The supported portion 92 is rotatably connected to the left and right support portions 83 of the first operating member 80 via the second connecting shaft SF2.

[0062] As a result, as shown in Figures 3(a) and 4(b), the second operating member 90 is rotatable counterclockwise around the second pivot axis X12 relative to the first operating member 80. The second gripping portion 91 of the second operating member 90 extends from the second pivot axis X12 toward the first pivot axis X11.

[0063] Returning to Figure 2, the projection 93 protrudes downward from the second gripping portion 91. The projection 93 enters the hole 81A of the first operating member 80 and the hole 71A of the base member 70, and protrudes below the main body portion 71 of the base member 70. The width of the projection 93 from side to side is slightly smaller than the width of the hole 81A. As a result, the lateral movement of the projection 93 is restricted by the left and right edges of the hole 81A. The projection 93 has a second mounting hole 93A as an example of a second mounting portion. A wire W2 is attached to the second mounting hole 93A.

[0064] As shown in Figure 4(a), the second pivot shaft X12 is positioned forward and away from the first pivot shaft X11. The first mounting hole 84A and the second mounting hole 93A are located between the first pivot shaft X11 and the second pivot shaft X12 in the front-rear direction.

[0065] In the longitudinal direction, the distance from the first drive shaft X11 to the first mounting hole 84A is greater than the distance from the first mounting hole 84A to the second drive shaft X12. In the longitudinal direction, the distance from the first drive shaft X11 to the second mounting hole 93A is greater than the distance from the second mounting hole 93A to the second drive shaft X12.

[0066] The second drive shaft X12 is located above the first drive shaft X11. The second gripping section 91 is located above the first drive shaft X11.

[0067] As the operating mechanism LM is configured as described above, when the user operates the second operating member 90, as shown in Figure 4(b), only the second operating member 90 moves, and only the wire W2 is pulled upward. Also, as shown in Figure 4(c), when the user operates the first operating member 80, the second operating member 90 rotates together with the first operating member 80, and both wires W1 and W2 are pulled upward.

[0068] Next, the operation of each component when operating the vehicle seat S will be explained with reference to Figure 14. When moving the vehicle seat S by sliding it, the user hooks their finger onto the end of the second operating member 90 on the side where the word "Slide" is written, as shown in Figure 3(c), and pulls the second operating member 90 upward. When the second operating member 90 is pulled upward, as shown in Figure 5(b), only the wire W2 is pulled upward, and the slide lock member 11 rotates from the slide lock position to the slide release position while the reclining lock release member 30 remains stopped.

[0069] This unlocks the slide mechanism, allowing the vehicle seat S to move forward and backward. As a result, the user can adjust the forward and backward position of the vehicle seat S while maintaining its orientation (the tilt of the seat back S2).

[0070] When the vehicle seat S is moved in a reclining motion, the user hooks their finger onto the end of the first operating member 80 on the side marked "Reclining" and pulls the first operating member 80 upward, as shown in Figure 3(c). When the first operating member 80 is pulled upward, the second operating member 90 also rotates together with the first operating member 80, so that both wires W1 and W2 are pulled upward, as shown in Figure 5(c). When wires W1 and W2 are pulled upward, the slide lock member 11 rotates from the slide lock position to the slide release position, and the reclining lock release member 30 rotates from the lock position to the release position.

[0071] This releases the slide lock and the recline lock, allowing the vehicle seat S to move forward and backward, and the seat back to rotate. As a result, the user can, for example, move the vehicle seat S forward while folding the seat back S2 to expand the cargo space at the rear of the vehicle.

[0072] The method for manufacturing the aforementioned operating mechanism LM will be described below. First, the base member 70, the first operating member 80, the second operating member 90, the first connecting shaft SF1, and the second connecting shaft SF2 are prepared (preparation step). After the preparation step, the second operating member 90 is placed on top of the first operating member 80, and the second connecting shaft SF2 is passed through the holes 83A and 92A to attach the second operating member 90 to the first operating member 80 (second operating member attachment step). Specifically, the end of the second operating member 90 on the second rotation axis X12 side is attached to the part of the first operating member 80 that is away from the first rotation axis X11. Also, in the second operating member attachment step, the second mounting hole 93A is positioned between the first rotation axis X11 and the second rotation axis X12 in the front-rear direction. In the second operating member attachment step, the second gripping part 91 is placed on top of the first gripping part 81 from above. Furthermore, in the second operating member mounting step, when the second operating member 90 is placed on top of the first operating member 80, the protruding portion 93 of the second operating member 90 is inserted into the hole 81A of the first operating member 80. In addition, in the second operating member mounting step, in order to prevent the second connecting shaft SF2 from coming off the first operating member 80, both ends of the second connecting shaft SF2 may be fixed to the first operating member 80 with adhesive or the like, for example.

[0073] After the second operating member mounting process, the first operating member 80 with the second operating member 90 attached is placed on top of the main body portion 71 of the base member 70, and the first connecting shaft SF1 is passed through the holes 72C and 82A to attach the first operating member 80 to the base member 70 (first operating member mounting process). Specifically, the end of the first operating member 80 on the first rotation axis X11 side is attached to the base member 70. In the first operating member mounting process, the first mounting hole 84A is positioned between the first rotation axis X11 and the second rotation axis X12 in the front-rear direction. Also in the first operating member mounting process, the connecting portion of the first operating member 80 and the second operating member 90 is placed between the two cover portions 72A that protrude from both ends in the left-right direction of the main body portion 71.

[0074] Furthermore, in the first operating member mounting step, when the first operating member 80 with the second operating member 90 attached is placed on the main body portion 71 of the base member 70, the respective protrusions 84 and 93 of each operating member 80 and 90 are inserted into the holes 71A of the base member 70. In addition, in the first operating member mounting step, in order to prevent the first connecting shaft SF1 from coming off the base member 70, both ends of the first connecting shaft SF1 may be fixed to the base member 70 with adhesive or the like, for example.

[0075] Note that the order of the second operating member mounting step and the first operating member mounting step may be reversed. Also, the first connecting shaft SF1 may be fixed to the first operating member 80. The second connecting shaft SF2 may be fixed to the second operating member 90.

[0076] As described above, the following effects can be obtained according to this embodiment. Since the second operating member 90 is positioned overlapping the first operating member 80, the installation space required for multiple operating members can be reduced compared to a configuration where, for example, the first operating lever and the second operating lever are positioned without overlapping. Furthermore, when the first operating member 80 is operated, both the slide lock member 11 and the reclining lock release member 30 move, thus improving operability.

[0077] By configuring the first operating member 80 to extend forward from the first pivot axis X11, the second pivot axis X12 to be located forward and away from the first pivot axis X11, and the second operating member 90 to extend from the second pivot axis X12 toward the first pivot axis X11, the rotation directions of the first operating member 80 and the second operating member 90 are opposite, thus preventing the user from accidentally operating the wrong operating member.

[0078] Since the connecting portion between the first operating member 80 and the second operating member 90 is covered by the cover portion 72A of the base member 70, the cover portion 72A can prevent dust from entering the connecting portion between the first operating member 80 and the second operating member 90.

[0079] Since the second rotation shaft X12 and the second gripping portion 91 are located above the first rotation shaft X11, for example, compared to a configuration where the first rotation shaft is located above the second gripping portion, the upward protrusion of the first operating member 80 can be suppressed.

[0080] Since the protruding portion 93 of the second gripping portion 91 fits into the hole 81A of the first gripping portion 81, it is possible to suppress the lateral displacement of the second gripping portion 91 relative to the first gripping portion 81.

[0081] Since the first information G1 is located at one end of the upper surface 91A of the second operating member 90 on the side of the second rotation axis X12, and the second information G2 is located at the other end opposite to the one end of the upper surface 91A, the respective information G1 and G2 are displayed on the side of the two operating members 80 and 90 where the user's fingers are placed, accidental operation can be suppressed.

[0082] Furthermore, the present invention is not limited to the embodiments described above, and can be used in various forms as illustrated below.

[0083] The reclining lock release member and the slide lock release member may be movable in a straight line.

[0084] The connecting member is not limited to a wire; it may also be a link mechanism, for example.

[0085] In the above embodiment, a vehicle seat S used in an automobile was given as an example of a vehicle seat, but the present invention is not limited thereto and can also be applied to other vehicle seats, such as seats used in ships and aircraft.

[0086] The second operating member may be rotatably supported by a member other than the first operating member, such as a base member.

[0087] The first and second drive axes may be the same axis.

[0088] The structure may include an overlap between a part of the first operating member and a part of the second operating member.

[0089] The base frame may be the cushion frame that constitutes the seat cushion. In other words, the back frame may be rotatably supported on the cushion frame via a reclining mechanism.

[0090] The elements described in the above embodiments and modifications may be implemented in any combination. [Explanation of symbols]
