Description

Portable posture support seat

[0001] The present invention relates to a portable posture-maintaining assist seat, and more specifically, to a portable posture-maintaining assist seat suitable for use by persons with disabilities, although not limited thereto.

[0002] In general, it is important for individuals with brain lesions, lower limb paralysis, and patients who have undergone hip dislocation surgery to maintain proper posture when sitting in a chair. This is because if such individuals sit in a standard chair used by the general public, their lower bodies may become deformed due to factors such as leg adduction.

[0003] To this end, specialized chairs are being used to maintain the posture of people with disabilities, particularly to alleviate or prevent internal rotation.

[0004] However, this specialized chair is not a unit that can be installed or disassembled as needed for general chairs, such as car seats, airplane seats, or wheelchairs; rather, it is an independent, specialized chair designed specifically for preventing internal shock. Therefore, a disadvantage of this specialized chair is that it cannot be selectively installed and used on car seats, airplane seats, wheelchairs, etc., only when necessary.

[0005] An auxiliary seat has been proposed that can be selectively installed and removed as needed for vehicle seats, airplane seats, wheelchairs, etc., by improving upon the shortcomings of dedicated chairs.

[0006] However, conventional auxiliary sheets have the disadvantage that their complex structure makes installation and removal difficult and requires a long time. Additionally, even if conventional auxiliary sheets can be installed and removed, they have the disadvantage of being difficult to carry and move.

[0007] Therefore, conventional auxiliary sheets have the disadvantage that they are difficult to install / detach and use only when necessary, and are also difficult to carry, making it practically difficult to function as a portable auxiliary sheet.

[0008] In addition, conventional assistive seats have the disadvantage that they can only be used by people with disabilities and are difficult for the general public to use.

[0009] The present invention is intended to solve the aforementioned problems.

[0010] The objective of the embodiment of the present invention is to provide a portable posture-maintaining auxiliary seat that is easy to install and detach.

Additionally, in the accompanying drawings, certain components may be depicted in an exaggerated or reduced manner to aid in understanding the invention and are not limited to the forms drawn in the drawings.

[0072] With reference to FIGS. 1 and 2, an embodiment of a portable posture-maintaining assist seat according to the present invention will be described.

[0073] First, the overall structure of the portable posture-maintaining auxiliary seat (100) of the present embodiment (hereinafter referred to as the 'auxiliary seat' for convenience of explanation) will be described.

[0074] The auxiliary seat (100) of the present embodiment includes a seat plate (210) and a backrest plate (300). The seat plate (210) is the part where the user's buttocks touch, and the backrest plate (300) is the part where the user's back touches. The seat plate (210) and the backrest plate (300) can be detachably connected.

[0075] To support the user's pelvic area, a pair of detachable side cushions (800) may be further provided on both sides of the seat plate (210). Additionally, to support the user's back or waist area, a detachable back cushion (8) may be further provided on the back plate (300).

[0076] Meanwhile, the auxiliary seat of the present embodiment can be optionally installed and used on general chairs, such as vehicle seats, airplane seats, and wheelchairs, when necessary, and can be detached from the general chair for storage or transport when not needed. (For convenience of explanation, 'general chair' will be referred to as 'chair' below.) Additionally, the auxiliary seat of the present embodiment can be optionally installed or detached in accordance with the relevant regulations of the institution using the general chair.

[0077] When the auxiliary seat is installed on a general chair, such as a home chair, a vehicle chair, or a wheelchair, the part installed on the seat plate (10) of the chair is the seat plate seat (210), and the part installed on the back plate (20) of the chair is the back plate seat (300). When the auxiliary seat is installed on a chair, a back plate seat fixing member (500) for fixing the back plate seat (300) to the chair may be further provided.

[0078] When the auxiliary seat is detached from the chair, the backrest fixing member (500) can serve to bind the seat seat (210) and the backrest seat (300) together when the seat seat (210) and the backrest seat (300) are folded and overlapped (folded state). (See FIG. 7; a detailed method for detaching the auxiliary seat from the chair for storage and carrying will be described later.)

[0079] Meanwhile, to prevent the user's upper body from leaning forward, a pair of first belt sections (600) may be detachably provided in the vertical direction on the seat plate (210). Additionally, a pair of second belt sections (700) having a cushioning effect may be detachably provided on the first belt sections (600). Furthermore, a third belt section (900) may be detachably provided in the horizontal direction on the second belt sections (700). Additionally, the second belt sections (700) may be provided to be movable up and down on the first belt sections (600) according to the user's body dimensions. (See FIG. 3; details will be described later.)

[0080] Meanwhile, the seat plate (210) may be further equipped with a detachable anti-intrusion rod (400) to prevent internal intrusion of the user.

[0081] With reference to FIGS. 3 and FIGS. 4, each component of the auxiliary sheet of the present embodiment will be described in detail.

[0082] For the sake of convenience of explanation below, the front part of the auxiliary seat is referred to as the front and the rear part as the rear, and the left and right sides are used based on the view of the auxiliary seat from the front.

[0083] First, the seat plate (210) and backrest plate (300) are described.

[0084] When the auxiliary seat is installed on a general chair, such as a home chair, a car chair, or a wheelchair, the part installed on the seat of the chair is the seat seat (210), and the part installed on the back of the chair is the back seat (300).

[0085] It is preferable that the seat plate (210) and backrest plate (300) be made of a material with a cushioned shape. Additionally, to improve the convenience of installing and removing auxiliary seats from the chair and to enhance portability, the seat plate (210) and backrest plate (300) can be detachably connected.

[0086] The seat plate (210) and the backrest (300) can be detachably connected in various ways. For example, the seat plate (210) and the backrest (300) can be connected by Velcro (230, 320). The Velcro (230, 320) can be provided in a long left-right direction.

[0087] For example, one Velcro (230), either a female Velcro or a male Velcro, may be provided on the rear upper surface of the seat plate (210). Another Velcro (320), either a female Velcro or a male Velcro, may be provided on the lower rear surface of the backrest (300). It is also possible to use a two-way Velcro that does not distinguish between male and female on the seat plate (210) and the backrest (300). (For convenience of explanation, the term 'Velcro fastener (hook & loop fastener)' will be used below.)

[0088] Of course, the detachable connection between the seat plate (210) and the backrest (300) is not limited to Velcro. For example, it is possible to use snap button fasteners, zippers, etc.

[0089] Meanwhile, a backrest fixing member (500) may be provided on the backrest seat (300). The backrest fixing member (500) may be provided in a horizontal direction on the backrest seat (300).

[0090] The auxiliary seat (100) can be installed on the chair when necessary and removed when not necessary. Accordingly, the backrest seat fixing member (500) can be optionally fixed or removed when the auxiliary seat (100) is installed on the chair.

[0091] To this end, the backrest fixing member (500) must have a coupling structure that allows the seat plate (300) to be fixed and detached from the backrest of a chair, for example.

[0092] The backrest fixing member (500) may have a length-adjustable buckle coupling structure used in seat belts, general belts, etc. For example, the backrest fixing member (500) may include a first strap (510) and a corresponding second strap (520).

[0093] One side of the first strap (510) and the second strap (520) may be connected to the seat plate (300), and the other side may include a buckle. The first strap (510) may be equipped with one of a female buckle and a male buckle, and the second strap (520) may be equipped with the other of a female buckle and a male buckle. Additionally, it is preferable that the first strap (510) and the second strap (520) of the backrest fixing member (500) be adjustable in length.

[0094] The attachment and detachment of the first strap (510) and the second strap (520) of the backrest seat fixing member (500) is not limited to buckle connection, and other connection methods may be used. It is possible to use Velcro connection, snap button connection, zipper connection, etc.

[0095] Meanwhile, when the auxiliary seat (100) is separated from the chair, the backrest fixing member (500) can function to fix (bind) the components of the auxiliary seat (100). That is, when the auxiliary seat (100) is separated from the chair and the backrest seat (300) and seat plate (210) are folded, the backrest fixing member (500) can function to bind the backrest seat (300) and the seat plate (210) in a horizontal direction. (See FIG. 7; a detailed binding structure will be described later.)

[0096] Next, the side cushion (800) and back cushion (8) are described.

[0097] The auxiliary seat (100) of the present embodiment may optionally include a side cushion (800) and a back cushion (8). That is, the auxiliary seat (100) may include a side cushion (800) and a back cushion (8) when necessary.

[0098] The side cushion (800) is described as follows.

[0099] The side cushion (800) serves to support the user's legs, particularly the pelvic area. The side cushion (800) may have a cushioned pillow shape.

[0100] The side cushion (800) can be detachably attached to the left and right sides of the seat plate (210). For example, the side cushion (800) can be attached to the seat plate (210) with Velcro.

[0101] The side cushion (800) may include a connecting part (830) that is detachably coupled to the body (810) and the seat plate (210). For example, a pair of Velcro (24) may be provided in the front-rear direction on the lower surface of the seat plate (210), and a corresponding Velcro may be provided on the connecting part (830) of the side cushion (800). (See FIG. 4)

[0102] The attachment and detachment of the side cushion (800) and the seat plate (210) is not limited to Velcro fastening, and snap button fastening, zipper fastening, etc. may be used.

[0103] Meanwhile, the side cushion (800) may be provided with an auxiliary connecting part (820). When the auxiliary seat is not installed on the chair and is separated so that the seat plate (210) and back plate (300) are carried in a folded state, the auxiliary connecting part (820) may serve to additionally secure the side cushion (800). (See FIG. 7)

[0104] To this end, a button (340a) may be provided on the auxiliary connecting part (820). Correspondingly, buttons (340, 350) may be provided on the back of the backrest seat (300). (See FIG. 4) In addition to button connection, Velcro connection, zipper connection, etc., may be used for attaching and detaching the auxiliary connecting part (820) and the seat plate (210). (Detailed folding methods will be described later.)

[0105] The back cushion (8) is described as follows.

[0106] The back cushion (8) serves to support or hold the user's lower back. The back cushion (8) has a cushioned feel and can have a shape roughly like a pillow. The back cushion (8) can be attached to the backrest seat (300).

[0107] A pair of Velcro (82) may be provided vertically on the front of the backrest seat (300), and a corresponding Velcro (84) may be provided on the rear of the back cushion (8). By providing the Velcro (82) vertically on the backrest seat (300), the attachment position of the back cushion (8) can be adjusted vertically as needed.

[0108] The attachment and detachment of the back cushion (8) and the back seat (300) is not limited to Velcro fastening, and snap button fastening, zipper fastening, etc. may be used.

[0109] Next, the first belt section (600), the second belt section (700), and the third belt section (900) are described.

[0110] Basically, the first belt section (600), the second belt section (700), and the third belt section (900) serve to prevent the user's upper body from leaning forward.

[0111] As illustrated in FIG. 3, a pair of first belt portions (600) may be detachably provided in the vertical direction on the backrest seat (300). Accordingly, the user's upper body may be prevented from leaning forward by the first belt portions (600).

[0112] One side of the first belt portion (600) is fixed to the backrest seat (300), and the other side may be fixed to the backrest seat (300) so as to be detachably attached. For example, the lower side of the first belt portion (600) is fixed to the backrest seat (300), and the upper side may be fixed to the backrest seat (300) so as to be detachably attached.

[0113] When configured in this way, when the auxiliary seat (100) is installed on the chair, the first belt portion (600) can serve to support the user's upper body. Additionally, when the auxiliary seat (100) is detached from the chair, the first belt portion (600) can serve as a shoulder strap used when carrying the folded auxiliary seat (100) while moving. (The role of the shoulder strap will be described later.)

[0114] Meanwhile, a pair of second belt sections (700) having a cushioning effect may be further detachably provided on the first belt section (600). Additionally, a third belt section (900) connected horizontally to the left and right may be connected to the second belt section (700).

[0115] With reference to FIGS. 5 and 6, the second belt section (700) and the third belt section (900) will be described in detail.

[0116] The second belt section (700) may include a pair of left and right cushioning sections (741, 751) and a detachable section (742) that secures the cushioning sections (741, 751) to the first belt section (600) so as to be detachably attached. A plurality of cushioning pads (760) may be provided inside the cushioning sections (741, 751).

[0117] The detachable part (742) may include a pair of first bands (743) and second bands (744). The first bands (743) and second bands (744) may be attached and detached by Velcro fastening.

[0118] That is, with the first band (743) and the second band (744) open, the second belt portion (700) can be fitted onto the first belt portion (600), and then the first band (743) and the second band (744) can be fastened with Velcro. In this way, the second belt portion (700) is fixed to the first belt portion (600). The connection of the first band (743) and the second band (744) is not limited to this, and it is possible to use a snap button connection, a zipper connection, etc. Accordingly, when the user's upper body leans forward, the impact on the user's upper body can be cushioned by the cushioning portions (741, 751) of the second belt portion (700).

[0119] Meanwhile, a headrest (710) that is detachably connected by a connecting part (720, 730) may be provided on the upper side of the second belt part (700).

[0120] A connecting portion (720, 730) is provided on the upper rear side of the second belt portion (700), and a corresponding coupling portion (712, 714) may be provided on the rear side of the headrest. The coupling of the connecting portion (720, 730) of the second belt portion (700) and the coupling portion (712, 714) of the headrest may be achieved using Velcro, snap button, etc.

[0121] Referring to FIG. 5, a third belt section (900) may be provided in a horizontal direction on the second belt section (700). The third belt section (900) may include a pair of straps. A buckle connection may be used for attaching and detaching the pair of straps. The attachment and detachment of the pair of straps of the third belt section (900) may be achieved using a Velcro connection, a snap button connection, etc.

[0122] Referring again to FIG. 3, the internal anti-corrosion rod (400) is described as follows.

[0123] The inward rotation prevention rod (400) functions to prevent or alleviate the inward rotation of the user's legs when the user is seated on the auxiliary seat. Additionally, the inward rotation prevention rod (400) can function to alleviate the user's habit of falling and leg twisting.

[0124] The internal shock prevention rod (400) can be detachably attached to the front of the seat plate (210). The internal shock prevention rod (400) is preferably in the shape of a cylinder with an approximately elliptical cross-section, and its width decreases from the front to the rear.

[0125] A bracket (440) for an internal shock prevention rod may be attached to the lower part of the internal shock prevention rod (400) using screws or the like. Accordingly, the seat plate (210) may be provided with a bracket (420) for a seat plate to which the bracket (440) for an internal shock prevention rod is detachably attached.

[0126] A cap bracket (410) may be provided on the inside or bottom surface of the seat plate (210). The bracket (420) for the seat plate and the cap bracket (410) may be fixed to the bottom surface of the seat plate (210) with screws or the like.

[0127] The bracket (440) for the internal shock prevention rod can be detachably connected to the bracket (420) for the seat plate. Therefore, the internal shock prevention rod (400) can be detachably attached to the seat plate (210) as needed.

[0128] For example, the bracket (440) for the internal shock prevention rod may be detachably connected to the bracket (420) for the seat plate by means of hook connection, magnetic connection by means of a magnetic body (450, 430), etc. Alternatively, the internal shock prevention rod (400) and the seat plate (210) may be detachably connected in a different way. (The detailed detachable structure of the bracket (440) for the internal shock prevention rod and the bracket (420) for the seat plate will be described later.)

[0129] Meanwhile, a shielding member (220) may be provided at the front of the seat plate (210). The shielding member (220) serves to cover the bracket (420) for the seat plate when the internal shock prevention rod (400) is separated from the seat plate (210). To this end, a first coupling part (218a) is provided on one side of the shielding member (220), and a second coupling part (218) corresponding to the first coupling part (218a) may be provided on the seat plate (210). At least one of the first coupling part (218a) and the second coupling part (218) may be a magnetic material.

[0130] In addition, the first connecting part (218a) and the second connecting part (218) may use a connecting method such as Velcro connection or snap button connection.

[0131] With reference to FIGS. 1 and FIGS. 7, the method of installing, separating, and carrying the auxiliary seat (100) of the present embodiment on the chair (10, 20) will be described.

[0132] First, with reference to FIG. 1, the method of installing the auxiliary seat (100) of the present embodiment on the chair (10, 20) will be explained.

[0133] The auxiliary seat (100) can be installed on a general chair (10, 20), for example, a home chair, a vehicle chair, a wheelchair, etc.

[0134] The auxiliary seat (100) is placed on the chair (10, 20) with the seat plate (210) and back plate (300) of the auxiliary seat (100) combined. The part that touches the seat plate (10) of the chair (10, 20) is the seat plate (210) of the auxiliary seat, and the part that touches the back plate (20) of the chair is the back plate (300) of the auxiliary seat.

[0135] In order to secure the auxiliary seat (100) to the chair (10, 20), the backrest seat fixing member (500) of the auxiliary seat is wrapped around the backrest (20) of the chair and the buckle is locked, thereby completing the installation of the auxiliary seat (100).

[0136] Next, other components required for the auxiliary seat (100) may be optionally installed. For example, at least one of the internal shock prevention rod (400), back cushion (8), side cushion (800), first belt section (600), second belt section (700), and third belt section (900) may be optionally installed on the auxiliary seat (100).

[0137] When an internal shock prevention rod (400) is installed on the auxiliary seat (100), the covering member (220) in front of the seat plate (210) may be exposed in front of the seat plate (210) (see FIG. 1). Alternatively, the covering member (220) may be wrapped around the bottom surface of the seat plate (210) to connect the first connecting part (218a) and the second connecting part (218) so that it is not visible from the outside (see FIG. 4).

[0138] When the user sits on the seat plate (210) of the auxiliary seat (100), the user's buttocks press against the seat plate (210) of the auxiliary seat (100) and the user's back presses against the back plate (300) of the auxiliary seat (100).

[0139] When a user sits on the seat plate (210) of the auxiliary seat, the seat plate (210) of the auxiliary seat is pressed down by the user's body weight. Therefore, the seat plate (210) of the auxiliary seat can be fixed to the seat plate (10) of the chair to some extent without a separate fixing member (500). Additionally, the lower surface (bottom) of the seat plate (210) can be made of a non-slip pad to more effectively prevent the seat plate (210) from sliding off the seat plate (10) of the chair.

[0140] The backrest (300) of the auxiliary seat is fixed to the backrest (20) of the chair by means of a backrest fixing member (500). Therefore, the backrest (300) of the auxiliary seat remains fixed to the backrest (20) of the chair.

[0141] Accordingly, according to the present embodiment, an auxiliary seat (100) can be installed simply and easily on a general chair (10, 20), and the user's leg can be prevented from moving inward by means of the anti-inward movement rod (400) of the auxiliary seat.

[0142] Referring to FIG. 7, a structure for the convenience of carrying when the auxiliary seat (100) is separated from the chair is described.

[0143] If the auxiliary seat (100) is not used, the auxiliary seat (100) is removed from the chair. The method of removing the auxiliary seat (100) from the chair is the reverse of the method of installing the auxiliary seat on the chair.

[0144] With the auxiliary seat (100) detached from the chair, the backrest (300) of the auxiliary seat is folded toward the seat (210). Since the Velcro portion connecting the seat (210) of the backrest (300) and the backrest (300) can be made of a flexible material, it can be easily folded.

[0145] When the backrest seat (300) is folded against the seat seat (210), the backrest seat (300) and the seat seat (210) are secured by binding them horizontally using a backrest seat fixing member (500) connected to the backrest seat (300). The direction in which the backrest seat fixing member (500) is bound is the opposite direction when the auxiliary seat (100) is installed on the chair. Next, the backrest seat (300) and the seat seat (210) can be further secured by binding them vertically using a cover member (220) provided on the seat seat (210). To this end, a third connecting part (330) that can be detachably attached to the first connecting part (218a) of the cover member (220) may be provided on the back surface of the backrest seat (300). (See FIG. 4)

[0146] Accordingly, according to the present embodiment, when the backrest seat (300) and the seat seat (210) are in a folded state, the horizontal direction can be secured by using the backrest seat fixing member (500), and the vertical direction can be secured by using the covering member (220).

[0147] Meanwhile, the side cushion (800) is connected to the seat plate (210) via Velcro, but the connecting part (820) connected to the side cushion (800) may also be connected to the corresponding connecting part (340, 350) on the rear of the seat plate (210). (See FIG. 4)

[0148] Meanwhile, other parts such as an internal shock prevention rod (400), a back cushion (8), a second belt part (700), and a third belt part (900) can be inserted between the seat (210) and the backrest (300) before the seat (210) and the backrest (300) are folded. This is because, since the seat (210) and the backrest (300) have a flexible, thin plate-like shape, it is possible to insert the internal shock prevention rod (400), etc., between the seat (210) and the backrest (300). The side cushion (800) can be separated and inserted between the seat (210) and the backrest (300), or it can remain attached to the seat (210). FIG. 7 illustrates the side cushion (800) remaining attached to the seat (210).

[0149] Meanwhile, one side of the first belt portion (600) can be separated from the back seat (300) and exposed to the outside to form a shoulder splice.

[0150] Accordingly, according to the present embodiment, the auxiliary sheet (100) can be separated to form a bag shape with a small thickness and volume, thus providing the advantage of being convenient to carry. Additionally, since the first belt portion (600) can be used as a shoulder strap for the folded auxiliary sheet (100), carrying and moving the auxiliary sheet (100) is convenient.

[0151] Referring to FIG. 8, an embodiment of the seat plate (210) and back plate (300) is described.

[0152] The seat plate (210) may include an upper plate (212), a middle plate (214), and a lower plate (216) that are joined together. The upper plate (212) may be made of an elastic material, for example, a sponge quilting material. The middle plate (214) may be made of a material having a certain strength, for example, a plastic flat plate. The lower plate (216) may be made of a non-slip material, for example, a non-slip material.

[0153] Similar to the seat plate (210), the backrest (300) may include an upper plate (302), a middle plate (304), and a lower plate (306) that are joined together. The upper plate (302) may be made of an elastic material, for example, a sponge quilting material. The middle plate (304) may be made of a material having a certain strength, for example, a plastic flat plate. The lower plate (306) may be made of a non-slip material, for example, a non-slip material.

[0154] With reference to FIGS. 9 and FIGS. 10, another embodiment of the auxiliary sheet according to the present invention will be described.

[0155] This embodiment is intended to further enhance the function of the auxiliary seat. In addition to the components of the above-described embodiment, this embodiment may further include at least one of the leg fixing part (4) and the waist fixing part (5).

[0156] First, the leg fixing part (4) is described as follows.

[0157] A pair of leg fixing parts (4) can be detachably attached to the seat plate (210). The leg fixing parts (4) can fix the user's leg area, particularly the pelvis, and for convenience, the term leg fixing parts (4) is used.

[0158] The leg fixing part (4) may include a support part (42) that is detachably coupled to the seat plate (210) and a leg strap (46) connected to the support part (42) to fix the leg.

[0159] The seat plate (210) and the support member (42) can be detachably connected in various ways. For example, the seat plate (210) and the support member (42) can be connected by Velcro, snap button, zipper, etc. For example, Velcro (24) may be provided on the lower surface of the seat plate (210). A corresponding Velcro (44) may be provided on the upper surface of the support member (42). It is preferable that the Velcro be provided extending from the front to the rear.

[0160] The leg strap (46) may include a pair of leg straps (46a, 46b). The leg strap (46) may include a first strap (46a) and a second strap (46b) that is detachably coupled to the first strap (46a).

[0161] One side of the first strap (46a) and the second strap (46b) is fixed to the support member (42), and the other side may be provided with a detachable part, such as Velcro or a snap button. Accordingly, it is possible to adjust the inner diameter of the leg strap (46) to correspond to the thickness of the user's thigh.

[0162] The support portion (42) and leg strap (46) of the leg fixing portion (4) can be made of thin fabric or the like. Therefore, it is easy to fold and store the support portion (42) and leg strap (46) when the leg fixing portion (4) is separated from the seat plate (210).

[0163] Additionally, a flat plate having a predetermined strength, for example, a plastic flat plate (not shown), may be additionally provided between the support portion (42) and the bottom surface of the seat plate (210). Furthermore, instead of using a separate plastic flat plate, the support portion (42) of the leg fixing portion (4) may be made of a flat plate having a predetermined strength, for example, a plastic material.

[0164] The waist fixing part (5) is described as follows.

[0165] The waist fixing part (5) can be detachably attached to the seat plate (210). The waist fixing part (5) can fix the user's waist, hip joint, pelvis, etc., and for convenience, the term waist fixing part (5) is used.

[0166] The waist fixing part (5) may include a support part (52) that is detachably coupled to the seat plate (210) and a pair of waist straps (53) connected to the support part (52).

[0167] The seat plate (210) and the support member (52) can be detachably connected in various ways. For example, the seat plate (210) and the support member (52) can be connected by Velcro, snap button, zipper, etc. For example, Velcro (230) may be provided on the upper surface of the seat plate (210). A corresponding Velcro (52b) may be provided on the rear surface of the support member (52). The Velcro may be provided from left to right.

[0168] Additionally, Velcro (52a, 52b) may be provided on both the front and rear of the support member (52). In this case, the Velcro (52b) on the rear of the waist fixing member (5) may be attached to the upper surface of the seat plate (210), and the Velcro (320) of the back plate (320) may be attached to the Velcro (52a) on the front of the waist fixing member (5).

[0169] The waist strap (53) may include a first strap (53a) and a second strap (53b) that is detachably connected to the first strap (53a).

[0170] One side of the first strap (53a) and the second strap (53a) is connected to the support member (52), and the other side may be provided with a detachable part, such as Velcro or a snap button. Accordingly, it is possible to adjust the inner diameter of the waist strap (53) to correspond to the user's waist circumference.

[0171] The support part (52) and waist strap (53) of the waist fixing part (5) can be made of thin fabric or the like. Therefore, it is easy to fold and store the support part (52) and waist strap (53) when the waist fixing part (5) is separated from the seat plate (210).

[0172] Meanwhile, to further improve portability when the auxiliary seat (100) is separated from the chair, a shoulder strap (64) can be used to hang the folded auxiliary seat (100) on the guardian's shoulder. To this end, either the seat plate (210) or the backrest (300) may be further provided with a shoulder strap loop (64a) to which the shoulder strap (64) can be attached or detached. Therefore, when the auxiliary seat (100) is separated and carried, it is possible to carry it in the form of a bag by attaching the shoulder strap (64a) to the loop (64a) provided on the seat plate (210).

[0173] Referring to FIG. 10, the method of using the leg fixing part (4) and the waist fixing part (5) is explained.

[0174] When the auxiliary seat (100) is fixed to the chair (10, 20), the user (P) sits on the auxiliary seat (100). When the user (P) sits on the auxiliary seat, the user's waist and legs are fixed using the straps of the waist fixing part (5) and the leg fixing part (4) of the auxiliary seat (100).

[0175] Meanwhile, by using not only the leg fixing part (4) but also the anti-inversion rod (400), the user's leg can be prevented from inverting more effectively. Additionally, if necessary, it is possible to prevent the user's leg from inverting by using at least one of the leg fixing part (4) and the anti-inversion rod (400). (In FIG. 10, only the leg fixing part (4) is shown for convenience of explanation.)

[0176] When only the leg fixing part (4) is used, the leg fixing part (4) is small in volume and light, so it can be inserted more easily between the seat plate (210) and the backrest plate (300). Therefore, the auxiliary seat of this embodiment has the advantage of improved portability.

[0177] Referring to FIG. 11, an embodiment of the detachable structure of the internal anti-corrosion rod (400) of the present embodiment will be described.

[0178] As described above, the seat plate (210) may be provided with a retractable anti-intrusion rod (400). It is preferable that the retractable anti-intrusion rod (400) be easy and simple to attach and detach, and it is desirable that the anti-intrusion rod (400) be firmly fixed to the seat plate (210) when the anti-intrusion rod (400) is attached to the seat plate (210).

[0179] An example of a combined structure of an internal anti-corrosion rod (400) satisfying these conditions is described.

[0180] A bracket (420) for the seat is provided on the seat plate (210), and a bracket (440) for the anti-intrusion rod (400) is provided on the anti-intrusion rod. By attaching the bracket (440) for the anti-intrusion rod to the bracket (420) for the seat plate, the anti-intrusion rod (400) can be attached to the seat plate (210).

[0181] The bracket (440) for the internal anti-corrosion rod and the bracket (420) for the seat plate are described in detail.

[0182] A bracket (420) for the seat plate can be provided in the approximately front central part of the seat plate (210).

[0183] The bracket (420) for the seat plate can be a roughly plate-shaped member that is attached to the seat plate (210). The bracket (420) for the seat plate can be made of a material having a certain strength, such as metal or plastic.

[0184] The bracket (420) for the seat plate may include a detachable groove (422). The detachable groove (422) may be provided at the rear of the bracket (420) for the seat plate. The detachable groove (422) may be a predetermined space recessed from the rear to the front on the bottom surface of the upper surface (424) of the bracket (420) for the seat plate. (See FIG. 12 and FIG. 13)

[0185] The bracket (440) for the internal shock prevention rod may be a roughly plate-shaped member that is coupled to the lower part of the internal shock prevention rod (400). The bracket (440) for the internal shock prevention rod may be made of a material having a predetermined strength, such as metal or plastic.

[0186] The bracket (440) for the internal shock prevention rod may be equipped with a hook (442). The hook (442) may be provided at the rear of the bracket (440) for the internal shock prevention rod. The hook (442) may be in a shape that protrudes downward from the lower surface (444) of the bracket (440) for the internal shock prevention rod and extends forward again. That is, the hook (442) may be approximately 'L' shaped. Therefore, a predetermined space may be created between the lower surface (444) of the bracket (440) for the internal shock prevention rod and the hook (442).

[0187] Meanwhile, a magnetic body (430) may be additionally provided in the bracket (420) for the seat plate, and a corresponding magnetic body (450) may be additionally provided in the bracket (440) for the anti-insulation rod. If one of the bracket (420) for the seat plate and the bracket (440) for the anti-insulation rod is made of metal, a magnetic body may be provided in only one of them.

[0188] For convenience of explanation, the magnetic body (430) provided in the bracket (420) for the seat plate is referred to as the first magnetic body, and the magnetic body (450) provided in the bracket (440) for the internal shock prevention rod is referred to as the second magnetic body. In other embodiments as well, the terms first magnetic body and second magnetic body are used together as needed for convenience.

[0189] For ease of attachment and detachment, it is preferable that magnetic materials (430, 450) be provided on both the bracket (420) for the seat plate and the bracket (440) for the internal shock prevention rod. (The structure for ease of attachment and detachment will be described later.)

[0190] The reason the detachable groove (422) of the bracket (420) for the seat plate and the hook (442) of the bracket (440) for the internal shock prevention rod are positioned at the rear is as follows.

[0191] This is because when a user is sitting on the seat (210), the user's body is pushed from the rear to the front of the seat (210) in most cases. Therefore, when the user's body is pushed forward, the user's groin area pushes the anti-inversion rod (400) from the rear to the front, so the anti-inversion rod (400) is not detached from the seat (210).

[0192] Accordingly, the anti-increase rod (400) can be connected to the seat plate (210) from the rear to the front and separated from the front to the rear by means of the detachable groove (422) of the bracket (420) for the seat plate and the hook (442) of the bracket (440) for the anti-increase rod.

[0193] In addition, the attachment and detachment positions of the bracket (420) for the seat plate and the bracket (440) for the anti-insulation rod can be easily and automatically aligned by means of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-insulation rod. (The method of automatic alignment by means of the magnetic body will be described later.)

[0194] In addition, when the bracket (420) for the seat plate and the bracket (440) for the anti-intrusion rod are attached, the magnetic body (430, 450) can additionally perform the role of maintaining the state in which the bracket (420) for the seat plate and the bracket (440) for the anti-intrusion rod are attached.

[0195] Meanwhile, the upper surface (424) of the bracket (420) for the seat plate and the lower surface (444) of the bracket (440) for the internal shock prevention rod may be flat, but it is preferable that they have a predetermined shape for ease of attachment and detachment.

[0196] For example, as shown in FIG. 12, a concave portion (426) may be provided on the upper surface (424) of the bracket (420) for the seat plate and a protruding portion (446) may be provided on the lower surface (444) of the bracket (440) for the internal shock prevention rod. Conversely, a protruding portion may be provided on the upper surface (424) of the bracket (420) for the seat plate and a concave portion may be provided on the lower surface (444) of the bracket (440) for the internal shock prevention rod.

[0197] Accordingly, when the hook (442) of the anti-increase rod bracket (440) is inserted from the rear to the front into the detachable groove (422) of the bracket (420) for the seat plate, the concave portion (426) of the anti-increase rod bracket (440) can act as a guide rail. Additionally, when the anti-increase rod bracket (440) is attached to the bracket (420) for the seat plate, the concave portion (426) and the protruding portion (446) are mutually fitted together.

[0198] Meanwhile, as described above, the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-intrusion rod can automatically align the attachment and detachment positions of the bracket (420a) for the seat plate and the bracket (440a) for the anti-intrusion rod.

[0199] Referring to FIG. 13, the installation position and attachment method of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-insulation rod, which can be easily aligned for attachment and detachment, are described.

[0200] In this embodiment, the installation position and attachment method of the magnetic bodies (430, 450) that can almost automatically align the attachment positions of the bracket (420) for the seat plate and the bracket (440) for the anti-insulation rod by utilizing the positions of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-insulation rod are described.

[0201] FIG. 13 is a drawing for explaining the case (A1) in which the installation positions of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-electric rod are provided in correspondence with the position where the bracket (440) for the anti-electric rod is finally connected to the bracket (420) for the seat plate.

[0202] In other words, when the bracket (440) for the internal shock prevention rod is positioned to match the position of the bracket (420) for the seat plate, that is, when the hook (422) of the bracket (440) for the internal shock prevention rod is positioned at the position of the detachable groove (422) of the bracket (420) for the seat plate, the positions of the magnetic body (450) of the bracket (420) for the seat plate and the magnetic body (430) of the bracket (440) for the internal shock prevention rod coincide.

[0203] In general, to attach the anti-increase rod (400) to the seat plate (210), the user places the anti-increase rod (400) on the bracket (420) for the seat plate without being conscious of a specific position.

[0204] Then, due to the magnetic force of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-insulation rod, the bracket (440) for the anti-insulation rod is placed on the upper surface (424) of the bracket (420) for the seat plate, as shown in FIG. 13.

[0205] This is because the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-static rod attempt to align with each other due to mutual magnetic force.

[0206] Therefore, in order for the user to attach the internal anti-rotation rod (400) to the bracket (420) for the seat plate, the following three actions are required.

[0207] First, the user must push the anti-inversion rod (400) backward, and then lower it so that the hook (442) of the anti-inversion rod bracket (440) is positioned at the same height behind the detachable groove (422) of the seat bracket (420). Then, the user must push the anti-inversion rod (400) forward again so that the hook (442) of the anti-inversion rod bracket (440) is inserted into the detachable groove (422) of the seat bracket (420).

[0208] Therefore, in this embodiment, in order for the user to attach the anti-increase rod (400) to the bracket (420) for the seat plate, three actions are required: pushing the anti-increase rod (400) backward, lowering it downward, and pushing it forward again. Therefore, the convenience of attaching the anti-increase rod (400) to the bracket (420) for the seat plate is poor.

[0209] Referring to FIG. 14, an example of the installation position and attachment method of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-static rod, which can be easily attached and detached, is described.

[0210] This embodiment is an embodiment in which the installation positions of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the internal shock prevention rod are changed to solve the inconvenience of the above-described embodiment (Fig. 13).

[0211] In this embodiment, the installation positions of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the internal shock prevention rod are provided at a predetermined distance (B) apart from each other, with respect to the position where the bracket (440) for the internal shock prevention rod is finally coupled to the bracket (420) for the seat plate (see FIG. 14(b)). (In the embodiment of FIG. 13, the positions are mutually aligned.)

[0212] In other words, as illustrated in FIG. 14(a), the position of the hook (442) of the anti-intrusion rod bracket (440) is positioned rearwardly at a position corresponding to the detachable groove (422) of the bracket (420) for the seat plate, and the position of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the anti-intrusion rod bracket (440) coincide (A2).

[0213] In this embodiment, the method of attaching the internal anti-insulation rod (400) to the seat plate (210) is described as follows.

[0214] In order to attach the anti-increase rod (400) to the seat plate (210), the user naturally places the anti-increase rod (400) on the bracket (420) for the seat plate without being conscious of a specific position.

[0215] Then, as shown in FIG. 14(a), due to the magnetic force of the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-increase rod, the hook (442) of the bracket (440) for the anti-increase rod is separated from the rear of the detachable groove (422) of the bracket (420) for the seat plate. In addition, the hook (442) of the bracket (440) for the anti-increase rod is positioned at the same height vertically as the detachable groove (422) of the bracket (420) for the seat plate. This is because the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-increase rod tend to align with each other due to mutual magnetic force.

[0216] In the state of Fig. 14(a), if the user simply pushes the anti-intrusion rod (400) forward, the hook (442) of the bracket (440) for the anti-intrusion rod is naturally inserted into the detachable groove (422) of the bracket (420) for the seat plate, resulting in the state of Fig. 14(b).

[0217] Therefore, in this embodiment, the convenience of connection is improved because only one action of pushing the anti-increase rod (400) forward is required for the user to connect the anti-increase rod (400) to the bracket (420) for the seat plate.

[0218] Meanwhile, in this embodiment, the size (horizontal length) of the magnetic body (430) of the bracket (420) for the seat plate may be larger than the size of the magnetic body (450) of the bracket (440) for the anti-insulation rod. When configured in this way, when the anti-insulation rod (400) is coupled to the bracket (420) for the seat plate, the contact area between the magnetic body (430) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-insulation rod may be increased.

[0219] Referring to FIG. 15, another embodiment of the installation position and attachment method of the magnetic body of the bracket for the seat plate and the magnetic body of the bracket for the anti-static rod, which can be easily aligned for attachment and detachment, is described.

[0220] This embodiment is a modified version of the above-described embodiment (Fig. 14).

[0221] In the above-described embodiment (Fig. 14), one magnetic body (430) of the bracket (420) for the seat plate and one magnetic body (450) of the bracket (440) for the anti-insulation rod are provided. In contrast, in the present embodiment, the magnetic body of the bracket (420) for the seat plate may be provided in multiple quantities, for example, two (4300a, 4300b), and the magnetic body (450) of the bracket (440) for the anti-insulation rod may be provided in one quantity.

[0222] As illustrated in FIG. 15, one of the magnetic bodies (rear magnetic body) (4300a) of the bracket (420) for the seat is provided at a position corresponding to the position before the anti-increase rod (400) is coupled to the bracket (420) for the seat. The other of the magnetic bodies (front magnetic body) (4300b) of the bracket (420) for the seat is provided at a position corresponding to the position after the anti-increase rod (400) is coupled to the bracket (420) for the seat.

[0223] In this embodiment, the size (front-rear length) of the magnetic body (4300a, 4300b) of the bracket (420) for the seat plate may be the same as the size (front-rear length) of the magnetic body (450) of the bracket (440) for the internal shock prevention rod. Additionally, the spacing between the magnetic bodies (4300a, 4300b) of the bracket (420) for the seat plate may be larger than the size of the magnetic bodies (4300a, 4300b) of the bracket (420) for the seat plate.

[0224] In this embodiment, the method of attaching the internal anti-insulation rod (400) to the seat plate (210) is described as follows.

[0225] In order to attach the anti-increase rod (400) to the seat plate (210), the user naturally places the anti-increase rod (400) on the bracket (420) for the seat plate without being conscious of a specific position.

[0226] Then, as illustrated in FIG. 15(a), due to the magnetic force of the front magnetic body (4300a) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-increase rod, the hook (442) of the bracket (440) for the anti-increase rod is separated from the rear of the detachable groove (422) of the bracket (420) for the seat plate. In addition, the hook (442) of the bracket (440) for the anti-increase rod is positioned at the same height vertically as the detachable groove (422) of the bracket (420) for the seat plate. This is because the rear magnetic body (4300a) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the anti-increase rod tend to align with each other due to mutual magnetic force.

[0227] In the state of Fig. 15(a), if the user simply pushes the anti-intrusion rod (400) forward, the hook (442) of the bracket (440) for the anti-intrusion rod is naturally inserted into the detachable groove (422) of the bracket (420) for the seat plate, resulting in the state of Fig. 15(b).

[0228] In this state, the rear magnetic body (4300b) of the bracket (420) for the seat plate and the magnetic body (450) of the bracket (440) for the internal shock prevention rod are aligned with each other by mutual magnetic force.

[0229] Therefore, in this embodiment, the convenience of connection is improved because only one action of pushing the anti-increase rod (400) forward is required for the user to connect the anti-increase rod (400) to the bracket (420) for the seat plate.

[0230] Referring to FIG. 16, another embodiment of the installation position and attachment method of the magnetic body of the bracket for the seat plate and the magnetic body of the bracket for the anti-static rod, which can be easily aligned for attachment and detachment, is described.

[0231] This embodiment is a modified embodiment that improves the convenience of attaching and detaching the bracket for the seat plate and the bracket for the internal shock prevention rod, just like the embodiments described above. However, in this embodiment, the structure of the hook and the detachment groove, and the installation position of the magnetic body differ from the embodiments described above.

[0232] First, the structure of the bracket (420a) for the seat plate of the present embodiment will be explained.

[0233] At least one detachable groove (422a, 422b) and at least one hook (442a, 442b) may be provided in the bracket (420a) for the seat plate.

[0234] The structure of the multiple detachable grooves (422a, 422b) and hooks (442a, 442b) may be substantially the same. FIG. 16 illustrates the presence of two detachable grooves (422a, 422b) and two hooks (442a, 442b). Therefore, for convenience of explanation, among the detachable grooves (422a, 422b) and hooks (442a, 442b) of the bracket (420a) for the seat plate, the detachable groove (422a) and hook (442a) located at the rear will be described as an example.

[0235] Referring to FIG. 17, the structure of the bracket (420a) for the seat plate and the structure of the bracket (440a) for the internal shock prevention rod will be explained in detail.

[0236] In this embodiment, a detachable groove (422a) is provided inside the upper surface (424a-1, 424a-2) of the bracket (420a) for the seat plate. (In the embodiment of FIG. 14 and FIG. 15, a detachable groove (422) is provided on the lower surface of the rear end of the bracket (420) for the seat plate.)

[0237] The detachable groove (422a) of the bracket (420a) for the seat plate can be provided between the rear and the central portion.

[0238] For example, a detachable groove (422a) may be provided between the rear upper surface (424a-1) (for convenience, 'rear upper surface (424a)') and the central upper surface (424a-2) (for convenience, 'central upper surface') of the bracket (420a) for the seat plate.

[0239] In order to create a detachable groove (422a) between the rear upper surface (424a-1) and the central upper surface (424a-2) of the bracket (420a) for the seat, a recess (426) is provided between the rear upper surface (424a-1) and the central upper surface (424a-2). Additionally, the portion (425) (for convenience, 'protruding upper surface') adjacent to the detachable groove (422a) on the central upper surface (424a-1) may protrude upward above the rear upper surface (424a-1) and the central upper surface (424a-2). Therefore, the space created by the rear upper surface (424a-1), the protruding upper surface (425), and the recess (426) between them of the bracket (420a) for the seat can become the detachable groove (422a).

[0240] Additionally, the inner end (424a-1a) of the rear upper surface (424a-1) of the bracket (420a) for the seat plate may be inclined downward. Additionally, the inner end (425a) of the protruding upper surface (425) of the bracket (420a) for the seat plate may be inclined downward.

[0241] Meanwhile, the bracket (440a) for the internal anti-rotation rod may be provided with a hook (442a) corresponding to the detachable groove (422a) of the bracket (420a) for the seat plate.

[0242] In this embodiment, a hook (442a) is provided between the rear end (444a-1) and the central portion of the lower surface of the bracket (440a) for the internal shock prevention rod. (In the embodiments of FIG. 14 and FIG. 15, a hook (442) is provided on the lower surface of the rear end of the bracket (440) for the internal shock prevention rod.)

[0243] The hook (442a) of the bracket (440a) for the internal shock prevention rod can be provided at a position corresponding to the detachable groove (422a) of the bracket (420a) for the seat plate. That is, the hook (442a) of the bracket (440a) for the internal shock prevention rod can be provided between the rear and the center.

[0244] For example, a hook (442a) may be provided between the rear lower surface (444a-1) (for convenience, 'rear lower surface') and the central lower surface (444a-2) (for convenience, 'central lower surface') of the bracket (440a) for internal prevention rods.

[0245] The hook (442a) may include a portion (442a-2) (hereinafter referred to as the 'downward extension') protruding downward from the rear lower surface (444a-1) and central lower surface (444a-2) of the bracket (440a) for internal prevention rods, and a portion (442a-1) (hereinafter referred to as the 'forward extension') extending forward. That is, it may be approximately 'L' shaped.

[0246] Additionally, a recess (447) may be provided on the lower surface (444a) of the bracket (440a) for the anti-intrusion rod to accommodate the protruding upper surface (425) provided to create a detachable groove (422a) in the bracket (420a) for the seat plate. To this end, the portion (448) (for convenience, 'recessed lower surface') adjacent to the hook (442a) on the central upper surface (444a-2) of the bracket (440a) for the anti-intrusion rod may be recessed upward from the rear lower surface (444a-1) and the central lower surface (444a-2). Thus, the recess (448) of the bracket (440a) for the anti-intrusion rod may become a space that accommodates the protruding upper surface (425) of the bracket (420a) for the seat plate.

[0247] Additionally, the downward extension (442a-2) of the hook (442a) of the bracket (440a) for the internal shock prevention rod may be inclined in correspondence with the inclined portion (424a-1a) of the rear upper surface (424a-1) of the bracket for the seat plate. One side (448a) of the recessed portion (448) of the bracket for the internal shock prevention rod may be inclined in correspondence with the inclined portion (425a) of the protruding upper surface (425) of the bracket for the seat plate.

[0248] Meanwhile, a magnetic body (430a, 450a) may be provided on the central upper surface (424a-2) of the bracket (420a) for the seat plate and the central lower surface (444a-2) of the bracket (444a-2) for the internal shock prevention rod, respectively.

[0249] In this embodiment, unlike the above-described embodiment (the embodiment of FIG. 14 and FIG. 15), the magnetic body (430a) of the bracket (420a) for the seat plate and the magnetic body (450a) of the bracket (450a) for the anti-insulation rod may be provided at mutually corresponding positions based on the state in which the bracket (420a) for the seat plate and the bracket (440a) for the anti-insulation rod are combined.

[0250] In this embodiment, due to the structure of the detachable groove (422a) of the bracket (420a) for the seat plate and the hook (442a) of the bracket (440a) for the anti-insulation rod, the anti-insulation rod (400) can be automatically aligned when placed on the seat plate (210).

[0251] Referring to FIG. 18, the method of attaching and detaching the bracket (440a) for the internal anti-rotation rod to the bracket (420a) for the seat plate is explained.

[0252] The user places the anti-intrusion rod (400) on the bracket (420a) for the seat. At this time, the user places the anti-intrusion rod (400) naturally on the bracket (420a) for the seat without worrying about the position of the anti-intrusion rod (400).

[0253] At this time, the relative positions of the hook (442a) of the bracket (440a) for internal shock prevention rod and the detachable groove (422a) can be three. That is, the hook (442a) can be positioned behind the detachable groove (422a) of the bracket (420a) for the seat plate (Fig. 17(a)), positioned in front of the detachable groove (422a) (Fig. 17(b)), or positioned at a location corresponding to the detachable groove (422a) (Fig. 17(c).

[0254] If the hook (442a) of the bracket for the internal anti-rotation rod is positioned at the rear of the detachable groove (422a) of the bracket (420a) for the seat plate, as shown in FIG. 17(a), the state is described.

[0255] In this case, due to the self-weight of the anti-increase rod (400) and the magnetic force of the magnetic body (430a, 450a), the anti-increase rod (400) moves forward and downward, and the hook (442a) of the bracket for the anti-increase rod is naturally coupled to the detachable groove (422a) of the bracket (420a) for the seat plate. At this time, the rear of the hook (442a) of the bracket for the anti-increase rod is inclined downward, and correspondingly, the front end of the rear upper surface of the bracket (420a) for the seat plate is also inclined downward, so the hook (442a) of the bracket for the anti-increase rod can naturally slide into the detachable groove (422a) and be coupled.

[0256] If, as illustrated in FIG. 17(b), the hook (442a) of the bracket for the internal anti-rotation rod is positioned in front of the detachable groove (422a) of the bracket (420a) for the seat plate, the state is described.

[0257] In this case as well, generally, due to the weight of the anti-increase rod (400) and the magnetic force of the magnetic body (430a, 450a), the anti-increase rod (400) moves backward and downward, and the hook (442a) of the bracket for the anti-increase rod is naturally coupled to the detachable groove (422a) of the bracket (420a) for the seat plate.

[0258] If the hook (442a) of the bracket for the anti-inversion rod is placed on the detachable groove (422a) of the bracket (420a) for the seat plate, when the user pushes the anti-inversion rod (400) slightly backward, the anti-inversion rod (400) moves forward and downward due to the weight of the anti-inversion rod (400) and the magnetic force of the magnetic bodies (420a, 450a), and the hook (442a) of the bracket for the anti-inversion rod is naturally coupled to the detachable groove (422a) of the bracket (420a) for the seat plate. Since the front-to-back length of the hook (442a) of the bracket (440a) for the anti-inversion rod is short, the user only needs to push the anti-inversion rod (400) slightly backward.

[0259] If the hook (442a) of the bracket for the internal anti-rotation rod is positioned in a location corresponding to the detachable groove (422a) of the bracket (420a) for the seat plate, as illustrated in FIG. 17(c), the state is described.

[0260] In this case, due to the self-weight of the anti-increase rod (400) and the magnetic force of the magnetic body (420a, 450a), the anti-increase rod (400) moves downward and forward (444a), and the hook (442a) of the bracket for the anti-increase rod is naturally coupled to the detachable groove (422a) of the bracket (420a) for the seat plate.

[0261] As described above, when the user simply places the anti-increase rod (400) on the bracket (420a) for the seat, the hook (442a) of the bracket for the anti-increase rod is naturally coupled to the detachable groove (422a) of the bracket (420a) for the seat. Therefore, in this embodiment, the convenience of coupling the anti-increase rod (400) and the seat (210) is significantly improved.

[0262] Additionally, when the hook (442a) of the bracket for the anti-intrusion rod is naturally coupled to the detachable groove (422a) of the bracket (420a) for the seat, the positions of the magnetic body (430a) of the bracket (420a) for the seat and the magnetic body (450a) of the bracket (440a) for the anti-intrusion rod coincide. Therefore, in this state, the anti-intrusion rod (400) is firmly fixed to the seat (210) by the coupling of the hook (442a) and the detachable groove (422a) and the magnetic bodies (430a, 450a).

[0263] Referring to FIGS. 19 and 20, a preferred embodiment of the structure of the internal anti-corrosion rod (400) is described.

[0264] First, the overall structure of the internal prevention rod (400) is explained.

[0265] The internal anti-insulation rod (400) may include an internal frame and an external cushioning part.

[0266] The internal frame may include at least one support rod (463) and an upper plate (462) and a lower plate (461) located above and below the support rod (463), respectively. The support rod (463) may be an axial member that is long in the vertical direction. The upper plate (462) and the lower plate (461) may be approximately circular in shape and may be made of plywood. Additionally, an upper bracket (464) may be provided on the upper side of the upper plate (462). The upper bracket (464) may also be approximately circular in shape and may be made of plywood.

[0267] The upper bracket (464) and the top plate (462) can be connected to the support rod (463) by a bolt (468). The bottom plate (461) can be connected to the support rod (463) by a bolt (467).

[0268] Meanwhile, a cushion part (465) may be provided in the approximately cylindrical space formed by the top plate (462) and the bottom plate (461). The cushion part (465) may be provided with a sponge material to provide a cushioning effect.

[0269] Meanwhile, a bracket (440a) for an internal shock prevention rod can be attached to the lower plate (461) of the internal shock prevention rod (400) by means of a nut (466) and a bolt (not shown).

[0270] Referring to FIG. 21, an example of the structure of a bracket (420a) for a seat plate is described.

[0271] A bracket (420a) for the seat can be placed on the upper surface of the seat (210). A cap bracket (425) can be additionally placed on the lower surface of the seat (210). The bracket (420a) for the seat and the cap bracket (425) can be joined by a nut (422) and a bolt (423). For aesthetic purposes, a sticker (424) that can conceal the bolt (423) can be attached to the bolt (423).

[0272] Meanwhile, the above-described embodiment of the present invention can be installed on a chair and used for posture correction by not only people with disabilities but also the general public.
