[0006] A seat for achieving the above object includes a seat body having a seat portion and a backrest on which a person sits, and a cushion member detachable from at least one seating surface of the seat portion and the backrest, and the cushion member is characterized by having a handle that a person can grasp and carry.

[0007] Further, the cushion member includes a seat body having a seating portion and a backrest on which a person sits, and at least one of the seating portion and the backrest is attached to the seat body of a seat having a recess formed in a part of the seating surface. The cushion member has a handle that can be held by a person hooking a hand thereon, and is detachable from the recess and fits into the recess in the attached state.

[0008] According to such a configuration, the cushion member removed from the seat body can be easily carried. Further, since it can be easily carried, the cushion member can be used at the destination where it is carried.

[0009] In the above-described configuration, at least one of the seating portion and the backrest has a recess formed in a part of the seating surface, and the cushion member can be detachable from the recess and fit into the recess in the attached state.

[0010] According to this, the cushion member can be easily attached only by fitting it into the recess, and can be easily removed only by pulling out the cushion member fitted in the recess from the recess. That is, the cushion member can be easily attached and detached.

[0011] In the above-described configuration, the cushion member can have a seating cushion that is detachable from the seating surface of the seating portion and a backrest cushion that is detachable from the seating surface of the backrest, and the handle can be provided so as to connect the seating cushion and the backrest cushion.

[0012] According to this, since the cushion member can be carried by holding the handle with the seating cushion and the backrest cushion stacked, the cushion member having the seating cushion and the backrest cushion can be made compact and easily carried.

[0013] In the above-described configuration, the seat body has left and right child seat attachment portions for attaching a child seat, and the handle can be provided so as to be positioned between the left and right child seat attachment portions when the cushion member is attached to the seat body.

[0014] According to this, when attaching a child seat to a seat with a cushion member attached to the seat body, it is possible to prevent the handle from getting in the way.

[0015] In the above-described configuration, the seat body has left and right child seat attachment portions for attaching a child seat, and the handle can be provided so as to cover at least one of the left and right child seat attachment portions when the cushion member is attached to the seat body.

[0016] According to this, it is possible to realize a specification such that a child seat cannot be attached to the seat unless the cushion member is removed from the seat body.

[0017] In the above-described configuration, the cushion member has a first electric wire provided on the seat cushion, a second electric wire provided on the backrest cushion, and a third electric wire connecting the first electric wire and the second electric wire, and the third electric wire can be provided so as to pass through the handle.

[0018] According to this, in a configuration where the cushion member has electric wires, the third electric wire can be arranged neatly.

[0019] In the above-described configuration, the seat cushion and the backrest cushion can be such that their shapes and sizes are substantially the same.

[0020] According to this, by overlapping the seat cushion and the backrest cushion, the cushion member becomes more compact, so that the cushion member having the seat cushion and the backrest cushion can be carried more easily. Further, it becomes possible to replace the seat cushion and the backrest cushion and attach them to the seat body.

[0021] In the above-described configuration, the handle may have a hole or a recess for hooking a hand.

Effect of the Invention

[0022] According to the present invention, the cushion member can be carried easily.

[0023] Further, by making the cushion member detachable with respect to a recess formed in a part of the seat surface and having a configuration that fits into the recess in the attached state, the cushion member can be attached and detached easily.

[0038] As shown in FIG. 5, the backrest cushion 120 is detachable from the seating surface S20 of the backrest S2. Specifically, the backrest cushion 120 is detachable from the backrest recess 12. The backrest cushion 120 fits into the backrest recess 12 in a state of being attached to the seating surface S20 of the backrest S2. The backrest recess 12 has left and right inner surfaces 12A and 12B that sandwich the backrest cushion 120 in a state where the backrest cushion 120 of the cushion member 100 fits into the backrest recess 12. Further, as shown in FIG. 3, the backrest recess 12 has upper and lower inner surfaces 12C and 12D that sandwich the backrest cushion 120 in a state where the backrest cushion 120 fits into the backrest recess 12.

[0039] The backrest cushion 120 is formed so as to fit into the backrest recess 12 in a somewhat compressed state. Thereby, in a state where the backrest cushion 120 fits into the backrest recess 12, the left and right and upper and lower sides of the backrest cushion 120 are in close contact with the left and right and upper and lower inner surfaces 12A to 12D of the backrest recess 12. The backrest cushion 120 and the backrest recess 12 have substantially the same contour in a state where the backrest cushion 120 fits into the backrest recess 12.

[0040] As shown in FIG. 2(a), the handle 130 is a portion that a person can grasp by hooking a hand, and is provided so as to connect the seat cushion 110 and the backrest cushion 120. The handle 130 is, for example, a member having a substantially H shape made of cloth, leather, or the like, and having cutouts 131A and 131B in the upper and lower portions. The handle 130 is provided such that, for example, the lower end portion is connected near the rear end portion of the back surface (lower surface) of the seat cushion 110, and the upper end portion is connected near the lower end portion of the back surface (rear surface) of the backrest cushion 120.

[0041] As shown in Fig. 3, with the seat cushion 110 fitted into the seat recess 11, the lower part of the handle 130 enters the seat recess 11 together with the seat cushion 110 and is disposed between the rear side surface of the seat cushion 110 and the rear inner side surface 11D of the seat recess 11. Further, with the backrest cushion 120 fitted into the backrest recess 12, the upper part of the handle 130 enters the backrest recess 12 together with the backrest cushion 120 and is disposed between the lower side surface of the backrest cushion 120 and the lower inner side surface 12D of the backrest recess 12.

[0042] As shown in Fig. 2(b), the cushion member 100 is bent so that the upper and lower parts of the handle 130 overlap to form a substantially U-shape, and the back surfaces of the seat cushion 110 and the backrest cushion 120 are joined and overlapped with each other, so that the cushion member 100 can be carried by holding the handle 130, and is in a carry state. The handle 130 has a hole 131 for hooking a hand. The hole 131 is formed by a part of the notches 131A and 131B formed in the handle 130 and the edges of the seat cushion 110 and the backrest cushion 120.

[0043] As shown in Fig. 1, the seat body S0 further has left and right child seat attachment parts 50. The child seat attachment parts 50 are parts provided with fixing fittings and the like for attaching a child seat, and are arranged at a predetermined interval on the left and right. Note that, although a detailed description of the specific structure of the child seat attachment parts 50 is omitted in this specification, for example, a fixing structure of a child seat defined by ISOFIX, which is an international standard, can be adopted.

[0044] The handle 130 of the cushion member 100 is provided so as to be positioned between the left and right child seat attachment parts 50 when the cushion member 100 is attached to the seat body S0.

[0045] Specifically, the left and right child seat attachment portions 50 are arranged at positions that fit within the widths of the seat cushion 110 and the backrest cushion 120 in the left - right direction. The handle 130 has a left - right width smaller than the interval between the left and right child seat attachment portions 50, and is provided at a position corresponding to the position between the left and right child seat attachment portions 50 in the left - right direction. Specifically, the handle 130 is provided near the center of the cushion member 100 in the left - right direction. Thereby, when the cushion member 100 is attached to the seat body S0, the entire handle 130 is arranged between the left and right child seat attachment portions 50.

[0046] The vehicle seat S further includes a holding mechanism 60. The holding mechanism 60 is a mechanism for suppressing the downward slip of the backrest cushion 120 fitted in the backrest recess 12 when the lower end thereof is displaced forward as shown by the virtual line in FIG. 3. In the present embodiment, the holding mechanism 60 has left and right latching portions 61.

[0047] The latching portion 61 is, for example, a member having a substantially right - angled triangular shape made of fabric, leather, or the like, and is provided on the backrest S2. Specifically, as shown in FIG. 2(a), the latching portion 61 is provided so as to cover a part of the lower portion of the backrest recess 12 when viewed from the front side. More specifically, the latching portion 61 is provided so as to cover the left and right corner portions located under the backrest recess 12 when viewed from the front side.

[0048] The left latching portion 61 is attached to the left - hand side and lower portion of the left corner portion located under the backrest recess 12 on the seat surface S20 of the backrest S2. Also, the right latching portion 61 is attached to the right - hand side and lower portion of the right corner portion located under the backrest recess 12 on the seat surface S20 of the backrest S2.

[0049] As shown in FIG. 5, the latching portion 61 is arranged to sandwich the backrest cushion 120 between itself and the bottom surface 12E of the backrest recess 12 in a state where the backrest cushion 120 is fitted into the backrest recess 12, thereby supporting the backrest cushion 120. Thereby, the latching portion 61 suppresses the lower end portion of the backrest cushion 120 fitted in the backrest recess 12 from moving forward.

[0050] According to the present embodiment described above, the cushion member 100 can be easily attached simply by fitting it into the recess 10, and can be easily removed simply by pulling out the cushion member 100 fitted in the recess 10 from the recess 10. Thereby, the cushion member 100 can be easily attached and detached.

[0051] In addition, since the cushion member 100 can be easily attached and detached, when the cushion member 100 gets dirty, it can be easily removed and washed or replaced. Also, by preparing a plurality of cushion members 100 having different colors, patterns, hardnesses, etc., for example, the cushion member 100 can be easily replaced according to the preference of the person sitting.

[0052] Also, by preparing a cushion member 100 having, for example, planar heaters 71A, 71B, fans 72A, 72B, vibrators 73A, 73B, etc. as shown in FIGS. 10(a) to 10(c) as the cushion member 100, heating functions, blowing functions, massage functions, etc. can be added to the vehicle seat S as a retrofit. Also, since the cushion member 100 can be easily attached and detached, it is easy to replace the cushion member 100 with one having another function, and the functions added to the vehicle seat S can be easily changed.

[0053] Further, since the recess 10 has inner surfaces 11A to 11D, 12A to 12D that sandwich the cushion member 100 in a state where the cushion member 100 is fitted into the recess 10, the cushion member 100 fitted in the recess 10 can be firmly held.

[0054] In addition, since the vehicle seat S is provided with the holding mechanism 60, it is possible to suppress the sliding down of the backrest cushion 120 fitted in the backrest recess 12. Specifically, by the backrest cushion 120 fitted in the backrest recess 12 being caught by the latching portion 61, it is possible to suppress the lower end portion of the backrest cushion 120 from shifting forward and sliding down.

[0055] In addition, since the cushion member 100 has a handle 130 that a person can hold onto, the cushion member 100 removed from the seat body S0 can be easily carried. Also, since it can be easily carried, the cushion member 100 can be used at the destination where it is carried.

[0056] In addition, since the cushion member 100 has a seat cushion 110 and a backrest cushion 120, and the handle 130 is provided so as to connect the seat cushion 110 and the backrest cushion 120, the cushion member 100 can be carried by holding the handle 130 with the seat cushion 110 and the backrest cushion 120 stacked. Thereby, the cushion member 100 having the seat cushion 110 and the backrest cushion 120 can be made compact and easily carried.

[0057] In addition, when the cushion member 100 is attached to the seat body S0, since the handle 130 is provided so as to be located between the left and right child seat attachment portions 50, it is possible to suppress the handle 130 from getting in the way when attaching a child seat to the vehicle seat S to which the cushion member 100 is attached to the seat body S0.

[0058] In addition, since the shapes and sizes of the seat cushion 110 and the backrest cushion 120 are substantially the same, the cushion member 100 becomes more compact by stacking the seat cushion 110 and the backrest cushion 120. Thereby, the cushion member 100 having the seat cushion 110 and the backrest cushion 120 can be more easily carried.

[0059] Further, since the shapes and sizes of the seat cushion 110 and the backrest cushion 120 are substantially the same, it is possible to interchange the seat cushion 110 and the backrest cushion 120 and attach them to the seat body S0. Further, when the cushion member 100 is removed from the seat body S0 and used at a place where it is carried, it is possible to use the seat cushion 110 and the backrest cushion 120 while they are stacked.

[0060] Although one embodiment of the invention has been described above, the present invention is not limited to the above embodiment, and can be appropriately modified and implemented as exemplified below. In the following, the same components as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.

[0061] In the above embodiment, the latching portion 61 of the holding mechanism 60 is provided so as to cover a part of the lower portion of the backrest recess 12 when viewed from the front side. However, the present invention is not limited to this, and the latching portion may be provided so as to cover the entire lower portion of the backrest recess 12 when viewed from the front side. Further, the latching portion may be made of a member constituting the skin and may be provided integrally with the skin.

[0062] Further, in the above embodiment, the holding mechanism 60 has a configuration having a latching portion 61, but the present invention is not limited to this.

[0063] For example, as shown in FIG. 6, the holding mechanism 60 may have a configuration having an engaging portion 62A and an engaged portion 62B. The engaging portion 62A is a concave portion provided on the left and right side surfaces of the backrest cushion 120. The engaged portion 62B is a convex portion provided on the left and right inner side surfaces 12A and 12B of the backrest recess 12 formed in the backrest S2. The engaged portion 62B is engaged with the engaging portion 62A in a state where the backrest cushion 120 is fitted into the backrest recess 12.

[0064] According to such a configuration, when the backrest cushion 120 is fitted into the backrest recess 12, the engaging portion 62A and the engaged portion 62B are engaged with each other, so that it is possible to suppress the backrest cushion 120 from slipping down.

[0065] In the modification shown in FIG. 6, the engaging portion 62A of the cushion member 100 is concave, and the engaged portion 62B of the backrest S2 is convex. However, the present invention is not limited to this. For example, the engaging portion may be convex and the engaged portion may be concave. Further, a plurality of sets of engaging portions and engaged portions may be provided on the left and right sides instead of one set. Further, the engaging portion and the engaged portion may have a shape combining concavity and convexity. Further, the engaging portion and the engaged portion may have different concave and convex shapes on the left and right sides. Further, the engaging portion may be provided on the back surface of the backrest cushion 120, and the engaged portion may be provided on the bottom surface of the backrest recess 12.

[0066] Further, as shown in FIG. 7, the holding mechanism 60 may have a configuration including a first magnetic member 63A and a second magnetic member 63B. A plurality of first magnetic members 63A are provided on the backrest S2. The first magnetic member 63A is provided in a fixed state between the bottom surface of the pad recess 32A of the backrest pad 32 and the backrest skin 42.

[0067] A plurality of second magnetic members 63B are provided on the backrest cushion 120. The plurality of second magnetic members 63B are respectively provided at positions facing the corresponding first magnetic members 63A in a state where the backrest cushion 120 is fitted into the backrest recess 12. The second magnetic member 63B is provided in a fixed state between the back surface of the backrest cushion pad 121 and the backrest cushion skin 122 of the backrest cushion 120.

[0068] One of the first magnetic member 63A and the second magnetic member 63B is made of a permanent magnet, and the other is made of a ferromagnetic material such as a permanent magnet or iron. Thereby, the second magnetic member 63B is attracted to the first magnetic member 63A by magnetic force in a state where the backrest cushion 120 is fitted into the backrest recess 12.

[0069] According to such a configuration, when the backrest cushion 120 is fitted into the backrest recess 12, the second magnetic member 63B is attracted to the first magnetic member 63A by magnetic force, so that the backrest cushion 120 can be prevented from slipping down.

[0070] Incidentally, the second magnetic member may be provided on the side surface of the backrest cushion 120, and the first magnetic member may be provided on the inner side surface of the backrest recess 12.

[0071] Also, as shown in FIG. 8, the holding mechanism 60 may be configured to include a friction member 64. The friction member 64 is provided on the backrest cushion 120 and the backrest S2. Specifically, the friction member 64 is a belt-like member made of rubber, felt, or the like, and includes a first friction member 64A and a second friction member 64B. The first friction member 64A is provided on the left and right side surfaces of the backrest cushion 120, and the second friction member 64B is provided on the left and right inner side surfaces 12A and 12B of the backrest recess 12 of the backrest S2.

[0072] The first friction member 64A and the second friction member 64B generate a frictional force between the left and right side surfaces of the backrest cushion 120 and the left and right inner side surfaces 12A and 12B of the backrest recess 12 formed in the backrest S2, thereby suppressing the backrest cushion 120 fitted in the backrest recess 12 from slipping down.

[0073] According to such a configuration, when the backrest cushion 120 is fitted in the backrest recess 12, a frictional force is generated between the backrest cushion 120 and the backrest S2, thereby suppressing the backrest cushion 120 from slipping down.

[0074] Incidentally, the first friction member may be provided on the back surface of the backrest cushion 120, and the second friction member may be provided on the bottom surface of the backrest recess 12. Also, the friction member may be provided only on one of the backrest cushion 120 and the backrest S2.

[0075] Further, as shown in FIG. 9, the holding mechanism 60 may be configured to include a surface fastener 65 composed of a first fastener member 65A and a second fastener member 65B. The first fastener member 65A and the second fastener member 65B are formed in a strip shape and are detachable from each other. A plurality of the first fastener members 65A are provided on the backrest S2. The first fastener members 65A are respectively provided on the left and right of the bottom surface of the backrest recess 12.

[0076] A plurality of the second fastener members 65B are provided on the backrest cushion 120. The plurality of second fastener members 65B are respectively provided at positions facing the corresponding first fastener members 65A in a state where the backrest cushion 120 is fitted into the backrest recess 12. The second fastener member 65B is detachable from the first fastener member 65A and adheres to the corresponding first fastener member 65A in a state where the backrest cushion 120 is fitted into the backrest recess 12.

[0077] According to such a configuration, when the backrest cushion 120 is fitted into the backrest recess 12, the fastener members 65A and 65B adhere to each other, thereby suppressing the backrest cushion 120 from slipping down.

[0078] Note that the second fastener member may be provided on the side surface of the backrest cushion 120, and the first fastener member may be provided on the inner surface of the backrest recess 12.

[0079] Further, the holding mechanism may be a configuration in which two or more of the configurations of the above-described embodiments and the modified examples shown in FIGS. 6 to 9 are combined. That is, the holding mechanism 60 may be a configuration including two or more of the latching portion 61, the engaging portion 62A and the engaged portion 62B, the first magnetic member 63A and the second magnetic member 63B, the friction member 64, and the surface fastener 65.

[0080] In addition, the holding mechanism may be provided not only on the backrest but also on the seat portion. For example, when the configuration of the modified example shown in FIGS. 7 and 9 is also provided on the seat portion S1, when the cushion member 100 is in a carry state (see FIG. 2(b)), the seat cushion 110 and the backrest cushion 120 may be provided so as to be attracted by magnetic force or adhered by a hook-and-loop fastener. Further, if the cushion member is firmly held by fitting into the concave portion and does not shift or move, the vehicle seat may be configured without a holding mechanism.

[0081] Also, as shown in FIG. 10(a), the cushion member 100 may further include electrical components 70, a battery 80 for supplying power to the electrical components 70, and electric wires 91 and 92.

[0082] As an example, the electrical components 70 are planar heaters 71A and 71B. The heater 71A is provided on the seat cushion 110, and the heater 71B is provided on the backrest cushion 120. The battery 80 is provided on the seat cushion 110. The battery 80 may be a rechargeable battery. Also, the battery 80 may be replaceable.

[0084] The electric wire 92 is an electric wire that connects the battery 80 and the electrical component 70 (heater 71B) provided on the backrest cushion 120. The electric wire 92 includes a first electric wire 92A that is a portion provided on the seat cushion 110, a second electric wire 92B that is a portion provided on the backrest cushion 120, and a third electric wire 92C that is a portion connecting the first electric wire 92A and the second electric wire 92B. The third electric wire 92C is provided so as to pass through the handle 130 that connects the seat cushion 110 and the backrest cushion 120.

[0085] The electrical components 70 provided in the cushion member 100 are not limited to the heaters 71A and 71B shown in Fig. 10(a). For example, as shown in Fig. 10(b), they may be fans 72A and 72B for cooling or the like, or as shown in Fig. 10(c), they may be vibrators 73A and 73B for generating vibrations.

[0086] According to such a configuration, in the case where the cushion member 100 has the electric wires 91 and 92, the third electric wire 92C can be arranged neatly.

[0087] Further, by providing the cushion member 100 with the electrical components 70 and the battery 80 connected by the electric wires 91 and 92, when the cushion member 100 is attached to the seat body S0, heating functions, air blowing functions, massage functions, etc. can be added to the vehicle seat S as retrofits. Also, when the cushion member 100 is removed from the seat body S0, these functions can be utilized even at the destination where it is carried.

[0088] Note that the electrical components provided in the seat cushion 110 and the electrical components provided in the backrest cushion 120 do not have to be of the same type and may be of different types. For example, a fan may be provided in the seat cushion 110 and a heater may be provided in the backrest cushion 120. Also, the electrical components provided in the seat cushion 110 do not have to be of one type and may be of two or more types. For example, both a heater and a fan may be provided in the seat cushion 110. The same applies to the electrical components provided in the backrest cushion 120.

[0089] Also, the battery may be provided not in the seat cushion 110 but in the backrest cushion 120, or may be provided in each of the seat cushion 110 and the backrest cushion 120. Also, the electric wire 92 may be a continuous electric wire or may be a connection of a plurality of electric wires, for example, a first electric wire 92A, a second electric wire 92B, and a third electric wire 92C which are different members.

[0090] Further, in the above-described embodiment, the handle 130 of the cushion member 100 was provided so as to be positioned between the left and right child seat attachment portions 50 when the cushion member 100 was attached to the seat body S0, but it is not limited thereto. For example, as shown in Fig. 11(a), the handle 230 may be provided so as to cover the left and right child seat attachment portions 50 when the cushion member 100 is attached to the seat body S0.

[0091] Specifically, the left and right child seat attachment portions 50 are arranged at positions within the widths of the seat cushion 110 and the backrest cushion 120 in the left-right direction. As shown in Figs. 11(b) and (c), the handle 230 has left and right widths substantially the same as the left and right widths of the seat cushion 110 and the backrest cushion 120, and is provided over the entire left-right width of the seat cushion 110 and the backrest cushion 120. Thereby, the handle 230 covers the left and right child seat attachment portions 50 when the cushion member 100 is attached to the seat body S0. The handle 230 has a hole 131 for hooking a hand.

[0092] According to such a configuration, it is possible to realize a specification such that a child seat cannot be attached to the vehicle seat S unless the cushion member 100 is removed from the seat body S0.

[0093] Although not shown, the handle may be provided so as to cover only one of the left and right child seat attachment portions 50 when the cushion member 100 is attached to the seat body S0.

[0094] Further, in the above-described embodiment, the vehicle seat S was a seat having a child seat attachment portion 50, such as the second-row seat or the third-row seat of an automobile, but it is not limited thereto. For example, the vehicle seat may be a seat without a child seat attachment portion, such as the driver's seat or the passenger seat of an automobile.

[0095] In addition, in the above embodiment, the seat cushion 110 and the backrest cushion 120 had substantially the same shape and size, but the present invention is not limited to this. For example, the seat cushion and the backrest cushion may have substantially the same shape but different sizes, or may have substantially the same size but different shapes. Further, the seat cushion and the backrest cushion may have different shapes and sizes.

[0096] In addition, in the above embodiment, the cushion member 100 had a configuration having both a seat cushion 110 that was detachable from the seat surface S10 of the seat portion S1 and a backrest cushion 120 that was detachable from the seat surface S20 of the backrest S2, but the present invention is not limited to this. For example, as shown in FIG. 12(a), the cushion member 100 may have a configuration having only the seat cushion 110 that is detachable from the seat surface S10 (seat recess 11) of the seat portion S1. In the modification shown in FIG. 12(a), only the seat portion S1 has a recess (seat recess 11) formed in a part of the seat surface S10, and no recess for attaching and detaching the cushion member to the seat surface S20 of the backrest S2 is formed.

[0097] Also, as shown in FIG. 12(b), the cushion member 100 may have a configuration having only the backrest cushion 120 that is detachable from the seat surface S20 (backrest recess 12) of the backrest S2. In the modification shown in FIG. 12(b), only the backrest S2 has a recess (backrest 12) formed in a part of the seat surface S20, and no recess for attaching and detaching the cushion member to the seat surface S10 of the seat portion S1 is formed.

[0098] In addition, when the cushion member 100 has only one of the seat cushion 110 and the backrest cushion 120, as shown in FIG. 13(a), the handle 330 is configured not to connect the seat cushion and the backrest cushion. The handle 330 is, for example, a substantially U-shaped member made of fabric, leather, or the like, and is provided connected near the end of the back surface of the seat cushion 110 or the backrest cushion 120. The handle 330 may be foldable so as to be attached to the back surface of the cushion member 100 as shown by the virtual line when attaching the cushion member 100 to the seat body S0.

[0099] Further, in the above embodiment, the handle 130 has a hole 131 for hooking the hand, but the present invention is not limited to this. For example, as shown in FIG. 13(b), the handle 430 provided on the back surface of the seat cushion 110 or the backrest cushion 120 may have a recess 431 for hooking the hand.

[0100] Further, in the above embodiment, the vehicle seat S mounted on an automobile is exemplified as the seat, but the present invention is not limited to this. For example, the seat may be a vehicle seat mounted on a vehicle other than an automobile, specifically, a railway vehicle, a ship, an aircraft, or the like. Further, the seat may be a seat used at home or a seat installed in a facility.

[0101] Further, in the above embodiment, the cushion member 100 is detachable with respect to the recess 10 formed in a part of the seat surface of the vehicle seat S, but the cushion member can be configured to be detachable with respect to the seat surface of a seat in which no recess is formed.
