Description

[Technical field]

[0001] The present disclosure relates to vehicle seats. [Background technology]

[0002] In a vehicle seat, a mechanism for folding a seat back so as to overlap a seat cushion is known (see Patent Document 1). In this mechanism, the seat back is folded by releasing an locked state with an operating cable. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4487939 Summary of the Invention [Problem to be solved by the invention]

[0004] There is a mechanism for flipping up the seat cushion and storing it, which uses a mechanism similar to the folding mechanism described above. In this mechanism, a cancel mechanism that releases the lock by an operating cable is placed on the cushion frame.

[0005] When the seat cushion is in a flipped-up state, an object such as a person or luggage may collide with the underside of the seat cushion opposite the seat surface. Because no pad is provided on the underside of the seat cushion, the attachment portion (i.e., the cap) of the operating cable in the cancellation mechanism may be damaged by the collision of such an object.

[0006] In order to prevent damage to the operating cable when the seat cushion is flipped up, it is possible to cover the back surface of the seat cushion with a resin cover. However, providing such a cover requires costs for the bracket and other parts for attaching the cover in addition to the cost of the cover itself. Also, a process for attaching the cover is required. As a result, the cost of the vehicle seat increases.

[0007] An object of one aspect of the present disclosure is to provide a vehicle seat that can suppress damage to an operating cable in a cancellation mechanism while keeping costs down. [Means for solving the problem]

[0008] One aspect of the present disclosure is a vehicle seat (1) including a seat cushion (2), a seat back (3), a cushion frame (4) supporting the seat cushion (2), and a lift-up device (8) configured to swing the seat cushion (2) between a seat position where the seat can be sat and a storage position lifted up from the seat position.

[0009] The flip-up device (8) has a locking mechanism (81A) switchable between a locked state that restricts the rocking of the seat cushion (2) and a released state that permits the rocking of the seat cushion (2), and a canceling mechanism (82) configured to switch the locking mechanism (81A) between the locked state and the released state.

[0010] The canceling mechanism (82) has a base (821) attached to the cushion frame (4), a wire (822A) configured to transmit a force for switching the state of the locking mechanism (81A), an operating cable (822) having a cover (822B) through which the wire (822A) is inserted and a cap (822C) connected to an end of the cover (822B), and an operating mechanism (824) connected to the wire (822A) of the operating cable (822).

[0011] The base (821) has an attachment portion (821F) to which a cap (822C) of the operating cable (822) is attached, and a pressing portion (821C) configured to restrict movement of the cap (822C) in a direction approaching the seat portion of the seat cushion (2).

[0012] According to this configuration, when an object hits the operating cable (822) while the seat cushion (2) is in the stored position, the cap (822C) hits the retaining portion (821C). As a result, the impact of the cap (822C) is transmitted to the retaining portion (821C), thereby suppressing damage to the cap (822C).

[0013] In addition, since the pressing portion (821C) is provided on the base portion (821) of the canceling mechanism (82), costs can be reduced compared to attaching a rigid cover to the rear surface of the seat cushion (2).

[0014] In one aspect of the present disclosure, the base portion (821) may have a first bracket (8211) fixed to the cushion frame (4) and a second bracket (8212) connected to the first bracket (8211). The second bracket (8212) may support the operation mechanism (824) and may have an attachment portion (821F). The first bracket (8211) may have a pressing portion (821C). With this configuration, the pressing portion (821C) can be provided on the base portion (821) while ensuring the degree of freedom in the shape of the second bracket (8212) that supports the operation mechanism (824). Therefore, the degree of freedom in designing the cancellation mechanism (82) is improved.

[0015] In one aspect of the present disclosure, the cushion frame (4) may have a first side frame (41) and a second side frame (42) that are arranged apart from each other in the seat width direction, and a front frame (43) that connects the first side frame (41) and the second side frame (42) in the seat width direction forward of the center positions of the first side frame (41) and the second side frame (42) in the seat front-rear direction. The base portion (821) may be fixed to the front frame (43). This configuration increases the design freedom of other operating devices (e.g., slide devices) attached to the cushion frame (4).

[0016] In one aspect of the present disclosure, the flip-up device (8) may be configured to flip up a rear end of the seat cushion (2) by swinging the seat cushion (2) about a front end of the seat cushion (2). With such a configuration, in a tumble-type vehicle seat (1) in which the seat cushion (2) is flipped up toward the front of the seat, damage to the operating cable (822) can be suppressed at low cost.

[0017] Note that the symbols in the above parentheses are examples showing the correspondence with the specific configurations etc. described in the embodiments described below, and the present disclosure is not limited to the specific configurations etc. shown by the symbols in the above parentheses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, embodiments to which the present disclosure is applied will be described with reference to the drawings. [1. First embodiment] [1-1. Configuration] The vehicle seat 1 shown in FIG. 1A includes a seat cushion 2 and a seat back 3.

[0020] The vehicle seat 1 is used as a seat for a passenger vehicle. The directions in the following description and in each drawing refer to the directions when the vehicle seat 1 is installed in a vehicle (i.e., a passenger vehicle). In this embodiment, the seat width direction coincides with the left-right direction of the vehicle, and the front of the seat coincides with the front of the vehicle.

[0021] The seat cushion 2 is a portion for supporting the buttocks of a seated person. The seat back 3 is a portion for supporting the back of the seated person.

[0022] The seat back 3 can swing in the front-rear direction of the seat with respect to the seat cushion 2. The seat back 3 is configured to swing between a use position shown in Fig. 1A and a forward-leaning position shown in Fig. 1B. The use position is a position where the seat back 3 can support the back of a seated occupant. The forward-leaning position is a position where the seat back 3 overlaps the seat cushion 2 from above.

[0023] The seat cushion 2 can swing up and down about the front end of the seat relative to the floor surface of the vehicle on which the vehicle seat 1 is installed. The seat cushion 2 is configured to swing between the seat position shown in Fig. 1A or 1B and the storage position shown in Fig. 1C.

[0024] The seat position is a position where the seat surface of the seat cushion 2 faces upward and an occupant can sit on the seat cushion 2. The storage position is a position where the rear end of the seat cushion 2 is flipped up from the seat position. In the following, unless otherwise specified, the "up-down direction" and the "front-rear direction" refer to the up-down direction and the front-rear direction when the seat cushion 2 is in the seat position.

[0025] The swinging of the seat cushion 2 is permitted only when the seat back 3 is in the forward tilted position. In addition, the seat back 3 swings up and down in a state overlapping the seat cushion 2 in association with the swinging of the seat cushion 2.

[0026] As shown in FIG. 2, the vehicle seat 1 includes a cushion frame 4, a back frame 5, a reclining device 6, a sliding device 7, and a flip-up device 8.

[0027] <Cushion frame> The cushion frame 4 supports the seat cushion 2. The cushion frame 4 includes a first side frame 41, a second side frame 42, a front frame 43, and a connecting rod 44.

[0028] The first side frame 41 and the second side frame 42 each extend in the front-rear direction and are spaced apart from each other in the seat width direction. The first side frame 41 is disposed on the left side of the second side frame 42.

[0029] The front frame 43 is configured with a pipe arranged so that the central axis is parallel to the seat width direction. The front frame 43 connects the first side frame 41 and the second side frame 42 in the seat width direction, in front of the center position of the first side frame 41 and the second side frame 42 in the seat front-rear direction. Specifically, the front frame 43 is fixed to the front end portion of the first side frame 41 and the front end portion of the second side frame 42.

[0030] The connecting rod 44 is configured with a pipe arranged so that the central axis is parallel to the seat width direction. The connecting rod 44 connects the rear end portion of the first side frame 41 and the rear end portion of the second side frame 42.

[0031] <Back frame> The back frame 5 supports the seat back 3. The back frame 5 is connected to the cushion frame 4 via a reclining device 6.

[0032] <Reclining device> The reclining device 6 is configured to rock the seat back 3 and the back frame 5 in the front-rear direction relative to the cushion frame 4.

[0033] The reclining device 6 switches between a locked state that restricts forward tilting of the back frame 5 and a movable state that permits forward tilting of the back frame 5. The reclining device 6 transitions from the locked state to the movable state by, for example, operating an operating lever attached to the back frame 5.

[0034] <Slide device> The slide device 7 is configured to slide the seat cushion 2 and the cushion frame 4 in the front-rear direction relative to the floor surface of the vehicle. The slide device 7 has a first movable rail 71A, a second movable rail 71B, a first fixed rail 72A, and a second fixed rail 72B.

[0035] The first movable rail 71A extends in the front-rear direction and is fixed to the first side frame 41. The first fixed rail 72A extends in the front-rear direction and supports the first movable rail 71A so that it can slide in the front-rear direction. The first fixed rail 72A is fixed to the floor surface of the vehicle via a first leg 83A.

[0036] The second movable rail 71B extends in the front-rear direction and is fixed to the second side frame 42. The second fixed rail 72B extends in the front-rear direction and supports the second movable rail 71B so that it can slide in the front-rear direction. The second fixed rail 72B is fixed to the floor surface of the vehicle via a second leg 83B.

[0037] <Flip-up device> The flip-up device 8 is configured to swing the seat cushion 2 and the cushion frame 4 between the seat position and the storage position. Specifically, the flip-up device 8 is configured to swing the seat cushion 2 about the front end portion of the seat cushion 2 (i.e., the end portion in front of the seat) to flip up (i.e., tumble) the rear end portion of the seat cushion 2 (i.e., the end portion in the rear of the seat).

[0038] As shown in FIG. 3, the flip-up device 8 has a first locking mechanism 81A, a second locking mechanism 81B, a canceling mechanism 82, a first leg 83A, and a second leg 83B.

[0039] (locking mechanism) The first locking mechanism 81A and the second locking mechanism 81B are each switchable between a locked state in which the seat cushion 2 and the cushion frame 4 are restricted from swinging and a released state in which the seat cushion 2 and the cushion frame 4 are permitted to swing.

[0040] The first locking mechanism 81A is fixed to the bottom surface of the first fixed rail 72A. The second locking mechanism 81B is fixed to the bottom surface of the second fixed rail 72B. The first locking mechanism 81A and the second locking mechanism 81B each have a locking claw 811 that engages with an anchor (not shown) fixed to the vehicle.

[0041] In the locked state, the first locking mechanism 81A and the second locking mechanism 81B are fixed to the anchors by the locking claws 811 engaged with the anchors, thereby restricting the rocking of the cushion frame 4. In the released state, the locking claws 811 are released from the anchors, allowing the first locking mechanism 81A and the second locking mechanism 81B to move away from the floor surface of the vehicle.

[0042] (Cancellation mechanism) The cancel mechanism 82 is configured to switch the first lock mechanism 81A and the second lock mechanism 81B between a locked state and an unlocked state. As shown in Fig. 4 and Fig. 5, the cancel mechanism 82 has a base 821, a first operation cable 822, a second operation cable 823, an operation mechanism 824, and a slide interlocking part 825.

[0043] (base) The base portion 821 is fixed to the front frame 43 of the cushion frame 4. The base portion 821 has a first bracket 8211, a second bracket 8212, a first fastener 8213, and a second fastener 8214.

[0044] The first bracket 8211 is a plate-like metal member having a frame 821A, a fixing portion 821B, a first pressing portion 821C, and a second pressing portion 821D.

[0045] The frame body 821A is disposed so as to overlap the second bracket 8212. The fixing portion 821B extends forward from the front end portion of the frame body 821A. The fixing portion 821B is fixed to the lower surface of the front frame 43 by, for example, welding.

[0046] The first pressing portion 821C extends rearward from the rear end portion of the frame body 821A in the vicinity of the first mounting portion 821F of the second bracket 8212. The first pressing portion 821C is disposed rearward of the first mounting portion 821F and at a position overlapping from above with the cap 822C of the first operation cable 822 attached to the first mounting portion 821F.

[0047] The first pressing portion 821C is configured to restrict movement of the cap 822C in a direction approaching the sitting portion of the seat cushion 2 (that is, upward when the seat cushion 2 is in the seat position, and forward when the seat cushion 2 is in the storage position). In other words, when a load is applied to the first operation cable 822 from below, the cap 822C comes into contact with the first pressing portion 821C from below, thereby suppressing deformation of the cap 822C.

[0048] Here, the seat cushion 2 has a pad (not shown) and a cover (not shown) that covers the pad. The "sitting portion of the seat cushion 2" includes the pad and a portion of the cover that covers the upper surface of the pad (i.e., a portion that constitutes the seat surface).

[0049] When viewed from above, the width of first pressing portion 821C along the radial direction of cap 822C is greater than the outer diameter of cap 822C. Also, the rear end of first pressing portion 821C is located forward of the rear end of cap 822C. In other words, first pressing portion 821C does not overlap cover 822B of first operation cable 822 from above.

[0050] The second pressing portion 821D extends rearward from the rear end of the frame body 821A in the vicinity of the second mounting portion 821G of the second bracket 8212. The second pressing portion 821D is disposed rearward of the second mounting portion 821G and at a position overlapping from above with the cap 823C of the second operation cable 823 attached to the second mounting portion 821G. The second pressing portion 821D is configured to restrict movement of the cap 823C in a direction approaching the sitting portion of the seat cushion 2.

[0051] When viewed from above, the width of second pressing portion 821D along the radial direction of cap 823C is greater than the outer diameter of cap 823C. Also, the rear end of second pressing portion 821D is located forward of the rear end of cap 823C. In other words, second pressing portion 821D does not overlap cover 823B of second operation cable 823 from above.

[0052] The second bracket 8212 is a plate-like metal member having a base plate 821E, a first attachment portion 821F, and a second attachment portion 821G.

[0053] The board 821E supports the operating mechanism 824. The board 821E is placed on the frame body 821A of the first bracket 8211 from below, and is connected to the frame body 821A by a first fastener 8213 and a second fastener 8214. In other words, the second bracket 8212 is attached to the cushion frame 4 via the first bracket 8211. The first fastener 8213 and the second fastener 8214 are each formed of a bolt and a nut.

[0054] The first attachment portion 821F extends downward from the rear end portion of the substrate 821E. The first attachment portion 821F has a groove in which a cap 822C of the first operation cable 822 is attached. The second attachment portion 821G extends downward from the rear end portion of the substrate 821E. The second attachment portion 821G has a groove in which a cap 823C of the second operation cable 823 is attached.

[0055] (1st control cable) The first operation cable 822 transmits an input to the operation mechanism 824 to the first lock mechanism 81A and the second lock mechanism 81B. The first operation cable 822 has a wire 822A, a cover 822B, and a cap 822C.

[0056] The wire 822A is a metal wire configured to transmit a force for switching the states of the first locking mechanism 81A and the second locking mechanism 81B to the first locking mechanism 81A and the second locking mechanism 81B. A first end of the wire 822A is connected to a first cam 824A of the operation mechanism 824. The wire 822A is bifurcated and has two second ends. The two second ends are connected to the locking claws 811 of the first locking mechanism 81A and the second locking mechanism 81B, respectively, as shown in FIG. 3.

[0057] When wire 822A is pulled by operating mechanism 824, locking claws 811 of first locking mechanism 81A and second locking mechanism 81B simultaneously move to a position where they are released from being locked to the anchor.

[0058] 4 and 5 is a resin or rubber tube through which the wire 822A is inserted. A first end of the cover 822B is connected to the base 821 via a cap 822C. The cover 822B is bifurcated and has two second ends. The two second ends are connected to the first locking mechanism 81A and the second locking mechanism 81B, respectively.

[0059] Cap 822C is a cylindrical member connected to a first end of cover 822B. Wire 822A passes through cap 822C and is connected to operation mechanism 824. Cap 822C is held by base 821 by being attached to first attachment portion 821F.

[0060] The cap 822C has a reduced diameter portion (i.e., a groove provided along the circumferential direction) sandwiched between two flanges. The cap 822C is attached to the first attachment portion 821F by inserting the reduced diameter portion into the groove of the first attachment portion 821F from below. The cap 822C is made of resin.

[0061] (Second control cable) The second operation cable 823 transmits the input of the flip-up operation to the operation mechanism 824. The flip-up operation may be input directly by an operation lever, for example, or may be input via the reclining device 6.

[0062] For example, a mechanism may be used in which the reclining device 6 is unlocked when an input is made using an operating lever, and then the input is transmitted to the second operating cable 823 when the seat back 3 is swung to the forward tilt position.

[0063] The second operation cable 823 has a wire 823A, a cover 823B, and a cap 823C.

[0064] The wire 823A is a metal wire configured to transmit a force for switching the states of the first locking mechanism 81A and the second locking mechanism 81B to a first cam 824A of the operating mechanism 824. A first end of the wire 823A is coupled to the first cam 824A of the operating mechanism 824. A second end of the wire 823A is coupled to the reclining device 6, for example, as shown in FIG.

[0065] 4 and 5 is a resin or rubber tube through which wire 823A is inserted. Cap 823C is a cylindrical member connected to a first end of cover 823B. Cap 823C is held by base 821 by being attached to second attachment portion 821G. Cap 823C has the same shape as cap 822C of first operation cable 822. Cap 823C is made of resin.

[0066] (operation mechanism) The operation mechanism 824 is connected to the wire 822A of the first operation cable 822 and the wire 823A of the second operation cable 823. The operation mechanism 824 has a first cam 824A and a second cam 824B.

[0067] The first cam 824A is rotatably attached to the base plate 821E of the second bracket 8212. A wire 822A of the first operation cable 822 and a wire 823A of the second operation cable 823 are connected to the first cam 824A.

[0068] The first cam 824A rotates between a relaxed position (see FIG. 5) where it does not pull the wire 822A of the first operation cable 822, and a pulling position (see FIG. 6) where it pulls the wire 822A. When the wire 823A of the second operation cable 823 is pulled, the first cam 824A rotates in the first direction D1 while pulling the wire 822A of the first operation cable 822.

[0069] That is, the first cam 824A transmits the input from the second operation cable 823 to the first operation cable 822. In this manner, the operation mechanism 824 is configured to operate the first lock mechanism 81A and the second lock mechanism 81B via the first operation cable 822.

[0070] The first cam 824A is biased by a spring in a second direction D2 opposite to the first direction D1. Therefore, when the input from the second operation cable 823 is released, the first cam 824A returns to the relaxed position where no input is transmitted to the first operation cable 822.

[0071] The second cam 824B is rotatably attached to the base plate 821E of the second bracket 8212. The second cam 824B rotates between a restriction position (see FIG. 5) where the rotation of the first cam 824A is restricted, and a release position (see FIG. 6) where the rotation of the first cam 824A is not restricted.

[0072] The second cam 824B in the restricting position abuts against the first cam 824A, thereby restricting the rotation of the first cam 824A in the relaxed position in the first direction D1. The second cam 824B in the released position does not interfere with the first cam 824A, and allows the first cam 824A to rotate to the pulling position.

[0073] A wire 825B of the slide interlocking unit 825 is connected to the second cam 824B. The second cam 824B moves from the restricted position to the released position by the tension of the wire 825B. The second cam 824B is also biased by a spring from the released position to the restricted position. Therefore, when the tension of the wire 825B is released, the second cam 824B returns to the restricted position.

[0074] (Slide interlocking part) The slide interlocking part 825 transmits the position of the cushion frame 4 in the front-rear direction to the operation mechanism 824. As shown in Fig. 3, the slide interlocking part 825 has a movable part 825A and a wire 825B.

[0075] The movable part 825A is fixed to the first side frame 41. The movable part 825A slides in the front-rear direction with respect to the floor surface of the vehicle together with the cushion frame 4. The wire 825B connects the movable part 825A and a second cam 824B of the operation mechanism 824. The wire 825B rotates the second cam 824B based on the position of the movable part 825A.

[0076] Specifically, the wire 825B moves the second cam 824B to the release position when the cushion frame 4 is in a position where it can be flipped up (for example, the frontmost position within the slidable range).

[0077] (Leg) The first leg 83A fixes the first fixed rail 72A to the floor surface of the vehicle. The first leg 83A has a first portion 831, a second portion 832, and a shaft portion 833.

[0078] The first part 831 is fixed to a front end of the first fixed rail 72A. The second part 832 is fixed to a floor surface of the vehicle. The shaft part 833 connects the first part 831 to the second part 832 so as to be able to swing. The swing central axis of the first part 831 is parallel to the seat width direction.

[0079] The second leg 83B fixes the second fixed rail 72B to the floor surface of the vehicle. The second leg 83B has a first portion 831, a second portion 832, and a shaft portion 833 similar to the first leg 83A.

[0080] <Flip-up operation> The operation of flipping up the cushion frame 4 from the state shown in FIG. 3 in which the cushion frame 4 is in the seat position and the back frame 5 is in the use position will be described.

[0081] First, the lock of the reclining device 6 is released. That is, the reclining device 6 is switched to a movable state that permits forward tilting of the back frame 5. In this state, the back frame 5 is moved to the forward tilted position.

[0082] Next, with the back frame 5 tilted forward, the cushion frame 4 is slid forward. When the cushion frame 4 is slid to a position where it can be flipped up, the lock by the second cam 824B of the operation mechanism 824 is released.

[0083] In this state, by inputting a flip-up operation to the second operation cable 823 of the cancel mechanism 82, the first lock mechanism 81A and the second lock mechanism 81B are simultaneously switched to the released state via the operation mechanism 824 and the first operation cable 822.

[0084] With the first locking mechanism 81A and the second locking mechanism 81B in an unlocked state, the rear end portion of the cushion frame 4 is lifted upward, causing the cushion frame 4 to swing about the first leg 83A and the second leg 83B. As a result, the cushion frame 4 moves to the storage position as shown in FIG.

[0085] The lower surfaces (rear surfaces in the flipped-up state) of the cushion frame 4 and the canceling mechanism 82 are at least partially covered with the cover of the seat cushion 2. The cover of the seat cushion 2 is formed of a low-rigidity material such as leather. In other words, the canceling mechanism 82 is not covered from below with a high-rigidity strength member.

[0086] [1-2. Effects] According to the embodiment described above in detail, the following effects can be obtained. (1a) When an object hits the first operation cable 822 while the seat cushion 2 is in the stored position, the cap 822C of the first operation cable 822 hits the first holding portion 821C. This causes the impact of the cap 822C to be transmitted to the first holding portion 821C, thereby suppressing damage to the cap 822C.

[0087] In addition, since the first pressing portion 821C is provided on the base portion 821 of the canceling mechanism 82, costs can be reduced compared to attaching a rigid cover to the rear surface of the seat cushion 2.

[0088] Similarly, with respect to second operation cable 823, second pressing portion 821D provided on base portion 821 can prevent damage to cap 823C at low cost.

[0089] (1b) Since the first bracket 8211 has the holding portions 821C, 821D, the holding portions 821C, 821D can be provided on the base 821 while ensuring the degree of freedom in the shape of the second bracket 8212 that supports the operation mechanism 824. Therefore, the degree of freedom in designing the cancellation mechanism 82 is improved.

[0090] (1c) Since the canceling mechanism 82 is fixed to the front frame 43 by the base 821, the design freedom of other operating devices (for example, the sliding device 7) attached to the cushion frame 4 is increased.

[0091] (1d) In a tumble-type vehicle seat 1 in which the seat cushion 2 is flipped up toward the front of the seat, damage to the first operation cable 822 and the second operation cable 823 can be suppressed at low cost.

[0092] 2. Other embodiments Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above-described embodiments and can take various forms.

[0093] (2a) In the vehicle seat of the above embodiment, the pressing portion of the canceling mechanism does not necessarily have to be provided on the first bracket. For example, the second bracket may have the pressing portion. Also, the pressing portion may be provided on a member other than the first bracket and the second bracket.

[0094] (2b) In the vehicle seat of the above embodiment, the base of the cancellation mechanism does not necessarily have to be fixed to the front frame of the cushion frame. For example, the base may be fixed to a side frame of the cushion frame.

[0095] (2c) In the vehicle seat of the above embodiment, the flip-up device may be configured to flip up one end (e.g., the left side) of the seat cushion in the seat width direction by swinging the seat cushion around the other end (e.g., the right side) of the seat cushion in the seat width direction.

[0096] (2d) In the vehicle seat of the above embodiment, the cancel mechanism does not necessarily have to be linked to the reclining device and the sliding device. In other words, the state of the reclining device and the sliding device does not have to be the unlocking condition in the cancel mechanism.

[0097] (2e) The vehicle seat of the above embodiment can also be applied to seats used in automobiles other than passenger cars, and seats used in vehicles other than automobiles, such as railroad cars, ships, and aircraft.

[0098] (2f) The function of one component in the above embodiments may be distributed among multiple components, or the functions of multiple components may be integrated into one component. In addition, a part of the configuration of the above embodiments may be omitted. In addition, at least a part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments. Note that all aspects included in the technical idea identified from the wording of the claims are embodiments of the present disclosure. [Explanation of symbols]
