Description

[Technical Field]

[0001] The present invention relates to a sheet-type air stretching exercise device that can be placed on a substantially horizontal surface such as a floor or bed, allowing the user to lie on their back and perform stretching exercises, and also allowing the user to sit on the seat and press against the treatment area. [Background technology]

[0002] In recent years, people have fewer opportunities to move their bodies and often remain in the same position for long periods of time. As a result, the muscles and tendons of the body often become contracted and stiff. Devices that can perform stretching exercises on such bodies (treatment areas) are commercially available. Patent Document 1, for example, discloses an exercise machine that can perform stretching exercises on treatment areas such as the back from the shoulders to the waist and the buttocks. The stretching exercise machine in Patent Document 1 is a seat-type machine in which the user lies supine on the seat and stretches the back, buttocks, etc.

[0003] Devices that use airbags to perform pressure actions on the treatment area of ​​a user are also commercially available. A device that uses airbags to perform pressure actions on leg parts such as the thighs and calves is disclosed, for example, in Patent Document 2. Patent Document 2 discloses a device that includes a belt-shaped first leg covering part that can be wrapped around the thighs and a belt-shaped second leg covering part that can be wrapped around the calves (see, for example, embodiment 3, Figure 7, etc.).

DETAILED DESCRIPTION OF THE INVENTION

[0029] An embodiment of an air stretching exercise device 1 according to the present invention will be described below with reference to the drawings. Note that the embodiment described below is an example of a specific embodiment of the present invention, and the configuration of the present invention is not limited to this specific example. In addition, for ease of viewing, some components have been omitted and the drawings have been drawn using virtual lines.

[0030] In explaining this embodiment, the directions of the sheet-type air stretch exercise device 1 are defined as follows for the sake of convenience.

[0031] 1 to 5, in the longitudinal direction of the seat-type air stretch exercise device 1, the side of the pillow part 2 is the "rear side," and the end side of the seat part 3 (main body part 5) opposite the pillow part 2 is the "front side." As shown in FIG. 4, when a user U sits on the seat-type air stretch exercise device 1 with their upper body B upright, the direction forward as seen from the user U is the "front side" of the air stretch exercise device 1.

[0032] 3, when a user U lies on his / her back on the sheet-type air stretching exercise device 1, the direction in which the user U looks up (toward the ceiling) is defined as the "upper side" of the air stretching exercise device 1. The left and right directions of the air stretching exercise device 1 are as shown in the drawing. [First embodiment] 1 to 4 show the configuration and usage of a first embodiment of an air stretching exercise device 1 according to the present invention.

[0033] 1 to 4, the air stretching exercise device 1 of the present invention can be placed on a flat surface such as a floor F or a bed, and can perform stretching exercises (treatment 1) to stretch and loosen treatment areas such as the back K and buttocks D of a supine user U, from the shoulders through the back to the waist, and also perform pressing actions (treatment 2) on treatment areas such as the thighs T and calves C of the legs L (lower limbs L) with the upper body B in an upright position, all with the same device. Furthermore, the air stretching exercise device 1 of this embodiment can be made compact and portable by rolling up the sheet portion 3.

[0034] The air stretching exercise device 1 of this embodiment comprises a pillow section 2 on which the head H of a user U lying on his / her back can be placed, a flexible sheet section 3 connected to the front side of the pillow section 2, and a first cushion 31 stored inside the sheet section 3 and inflating against the treatment area of ​​the user U to press and loosen the area. Airbags 4 and this first Airbags and a drive unit (not shown) that drives the first Airbags 4 simply Airbags It's called 4.

[0035] To give an example of the size of the air stretch exercise device 1 of this embodiment, the length (width) in the left-right direction of the seat portion 3 when unfolded is slightly larger than the shoulder width of the user U. Note that this embodiment is provided with a first extension portion 6 (details to be described later) extending to the right from the seat portion 3, and a second extension portion 7 (details to be described later) extending to the left from the seat portion 3. Therefore, the air stretch exercise device 1 has a length that reaches the upper arms of the user U when both arms are spread out to the left and right.

[0036] Furthermore, when the air stretching exercise device 1 is unfolded, its length in the front-to-back direction corresponds roughly to the length from the head H of the user U through the back K to the buttocks D. In other words, the air stretching exercise device 1 is large enough to accommodate the upper body B.

[0037] As shown in Figures 1 to 4, the pillow section 2 is a hollow member that is elongated in the left-right direction. This pillow section 2 is a storage body that stores a drive unit that drives the airbag 4. The pillow section 2 is capable of supporting the head H of a user U lying on their back on the seat section 3. The upper surface of the pillow section 2 may have, for example, a rounded shape or a flat shape. The lower surface of the pillow section 2 is made substantially horizontal so that the pillow section 2 can be placed on a flat surface such as the floor F.

[0038] The entire outer periphery of the pillow part 2 (particularly the upper surface side that comes into contact with the head H) is covered with a cushioning material. The pillow part 2 of this embodiment is a cylindrical member that is long in the left-right direction. Note that the shape of the pillow part 2 is not limited to the shape exemplified in this embodiment.

[0039] As shown in FIG. 4, when the user U sits down on the seat 3, the pillow 2 comes into contact with the buttocks D and serves as a stopper member that prevents the user U from moving backward.

[0040] The seat 3 is connected to the front side of the pillow 2. In other words, the pillow 2 is connected to the rear side of the seat 3. The seat 3 can be laid on a floor F or the like, and is large enough for the user U to sit on. The seat 3 is also large enough for the user U to lie on his back (with his upper body B placed on it). In other words, the seat 3 is large enough to be spread out under the area to be treated of the user U (for example, the legs L or the back K). The seat 3 is made of a flexible material such as cloth.

[0041] The seat part 3 has a main body part 5 having a size large enough for the treatment part of the user U to be placed on, a first extension part 6 extending in a strip shape from the main body part 5 to the right outer side in the width direction, and a second extension part 7 extending in a strip shape from the main body part 5 to the left outer side in the width direction. The first extension part 6 and the second extension part 7 are provided with a second airbag 4 that is inflated by air supplied from a drive part. Airbags 4 simply Airbags It's called 4.

[0042] The seat portion 3 also has a third extension portion 8 extending in a strip-like shape from the center of the main body portion 5 toward the upper right side, and a fourth extension portion 9 arranged to form a pair with the third extension portion 8 and extending in a strip-like shape toward the upper left side.

[0043] The main body 5 has an area large enough for the user U to lie on his / her back and sit down on. The main body 5 may be formed, for example, into a bag shape by sewing together the ends of two pieces of fabric material of the same shape (upper fabric material, lower fabric material) to provide a space inside.

[0044] A plurality of airbags 4 are provided inside the main body 5 (between the upper and lower cloths). The airbags 4 push upward the treatment areas such as the back K and buttocks D of a user U who is lying supine with their upper body B placed on the main body 5, thereby performing a stretching exercise to stretch and loosen them up. The airbags 4 also press against the treatment areas of the legs L (thighs T, calves C) of a user U who is sitting down on the main body 5 and raising their upper body B.

[0045] Furthermore, although not shown, the sheet portion 3 (main body portion 5) may be configured so that it can be wound into a roll toward the pillow portion 2. For example, the main body portion 5, in which the first extension portion 6 and the second extension portion 7 are folded, may be rolled up and placed in a parallel state next to the pillow portion 2, and the main body portion 5 may be engaged with a hook-and-loop fastener or the like to prevent it from unraveling. Alternatively, the main body portion 5, in which the first extension portion 6 and the second extension portion 7 are folded, may be wound around the outer periphery of the pillow portion 2 and gathered into a roll, and the main body portion 5 may be engaged with a hook-and-loop fastener or the like to prevent it from unraveling.

[0046] In this way, by winding the main body 5 into a roll and fastening it with hook-and-loop fasteners or the like, the air stretch exercise device 1 becomes compact and easy to carry. It also requires less storage space. Furthermore, by releasing the hook-and-loop fasteners, the main body 5 can be released from the pillow 2, and the air stretch exercise device 1 can be easily laid out on the floor F or the like.

[0047] 1 to 4, airbags 4 that are inflated by air supplied from a drive unit are provided at least on the front and rear sides inside the main body 5 (seat 3). In this embodiment, the airbags 4 include a rear airbag 4a and a front airbag 4b.

[0048] The rear airbags 4a include a first airbag 10 and a second airbag 11 (details of which will be described later). The front airbags 4b include a third airbag 14 and a fourth airbag 15 (details of which will be described later). That is, in this embodiment, four airbags 4 are stored inside the main body 5.

[0049] The plurality of airbags 4 are constructed by arranging air-impermeable fabric bodies (such as vinyl) on top and bottom, and joining the peripheries of the fabric bodies in an airtight state by welding or the like (welded structure).

[0062] A third air supply port 17 is provided on the rear side (pillow part 2 side) of the right air passage 16. The third air supply port 17 is connected to a pump inside the pillow part 2 via a third air supply hose. Air pressurized by the pump enters through the third air supply port 17, passes through the right air passage 16, and is supplied into the third airbag 14. The third airbag 14 is inflated by this pressurized air.

[0063] As the third airbag 14 inflates upward from the top surface of the main body 5, it lifts the treatment area, such as the right buttocks D, of the user U lying on his back on the main body 5, and provides a stretching motion to stretch and loosen it up. Additionally, as the third airbag 14 inflates upward, it lifts the treatment area, such as the right calf CR, of the user U sitting on the main body 5, and provides a pressing motion to loosen it up.

[0064] The fourth airbag 15 (left front airbag 15) is the third airbag 14, which is arranged by flipping it over (mirror-reversing it) to the left. That is, the fourth airbag 15 and the third airbag 14 are bilaterally symmetrical. The second airbag 11 and the fourth airbag 15 are provided in a row in the front-rear direction on the left side of the main body 5. The configuration of the fourth airbag 15 is substantially the same as that of the third airbag 14, so a detailed description thereof will be omitted. However, only an outline of the fourth airbag 15 will be described.

[0065] A left air passage 18 through which air supplied from a pump passes is provided behind the fourth airbag 15. The left air passage 18 is provided so as to pass through the left outer side of the second airbag 11.

[0066] A fourth air supply port 19 is provided on the rear side (pillow part 2 side) of the left air passage 18. Air pressurized by a pump inside the pillow part 2 enters through the fourth air supply port 19, passes through the left air passage 18, and is supplied into the fourth airbag 15, causing the fourth airbag 15 to inflate.

[0067] As the fourth airbag 15 inflates upward from the top surface of the main body 5, it lifts the treatment area, such as the left buttocks D, of the user U lying on his back on the main body 5, and provides a stretching motion to stretch and loosen the area. Additionally, as the fourth airbag 15 inflates upward, it lifts the treatment area, such as the left calf CL, of the user U sitting on the main body 5, and provides a pressing motion to loosen the area.

[0068] These first to fourth airbags 10 to 15 (rear airbag 4a and front airbag 4b) are controlled to repeatedly inflate and deflate independently or in cooperation with each other. This control provides various stretching exercises, pressing movements (massage movements), and the like.

[0069] The shapes of the first airbag 10 to the fourth airbag 15 are not particularly limited as long as they can perform stretching exercises on treatment areas such as the back K and buttocks D of a user U (upper body B) lying on their back on the main body 5 (seat 3), and can also provide a pressing action on treatment areas such as the thighs T and calves C of a user U seated on the main body 5.

[0070] As shown in Figs. 1 to 4, the first extension portion 6 is a member that extends in a strip shape (for example, like extending the right arm) from the right edge of the main body portion 5 outward in the width direction. In this embodiment, the first extension portion 6 is provided on the right edge at the rear side of the main body portion 5 (seat portion 3) on the pillow portion 2 side. The first extension portion 6 is provided, for example, at a location corresponding to the base of the right thigh TR when the user U is seated on the main body portion 5, or at a location corresponding to the right shoulder of the upper body B when the user U is lying supine on the main body portion 5.

[0071] The first extension portion 6 is flexible. Therefore, the first extension portion 6 can be folded and placed on top of the main body portion 5. The length of the first extension portion 6 is such that it can be wrapped around the right thigh TR (first treatment portion), which is one of the treatment portions of the user U placed on the main body portion 5. The first extension portion 6 may be made of the same fabric material as the main body portion 5.

[0072] That is, the first extension part 6 is a member that can be laid on the floor F or wrapped around the right thigh TR by pulling it from the right outer side to the inside. When the user U lies on his / her back on the main body part 5, the right arm of the user U can be placed on it.

The drive unit may be provided with a structure for heating air. That is, it is preferable to heat the pressurized air from the pump and provide warm air to the airbag 4, so that warm stretching exercise (pressure massage) can also be performed on the seat unit 3. [Usage] Next, a usage mode of the first embodiment of the air stretching exercise device 1 of the present invention will be described with reference to the drawings. [Treatment 1 (Stretching)] FIG. 3 shows usage mode 1 "Treatment 1" of the air stretch exercise device 1 of this embodiment.

[0111] As shown in FIG. 3, the air stretching exercise device 1 of this embodiment is capable of performing stretching exercises on treatment areas such as the back K and buttocks D of a user U to stretch and loosen them up.

[0112] In detail, the air stretching exercise device 1 allows the user U to place their head H on the pillow portion 2, lie on their back with their upper body B on the main body portion 5, and perform stretching exercises to stretch the treatment areas from their back K to their buttocks D by inflating and deflating (expanding and contracting) the airbags 4 built into the main body portion 5.

[0113] Here, the inflation and deflation of the first airbag 10 to the fourth airbag 15 in "Treatment 1" will be described. In this embodiment, the first airbag 10 to the fourth airbag 15 are configured to be capable of inflating and deflating independently and alternately. <Front and rear airbags inflate alternately> For example, the first airbag 10 and the second airbag 11 arranged on the rear side of the main body 5 constituting the seat 3 are inflated. Alternate inflation and deflation control may be performed so that the third airbag 14 and the fourth airbag 15 arranged on the front side of the main body 5 begin to inflate at the same time as the airbags 10 and 11 are deflated.

[0114] Specifically, when the first airbag 10 inflates, the right side of the back K of the user U lying on his back on the main body 5 is lifted, and when the second airbag 11 inflates, the left side of the back K of the user U is lifted, thereby performing a stretching exercise on the back K.

[0115] Next, the airbags 10 and 11 are deflated, and the third airbag 14 is inflated, thereby lifting the right buttock D of the user U, and the fourth airbag 15 is inflated, thereby lifting the left buttock D of the user U, thereby performing a stretching exercise for the buttocks D.

[0116] In other words, the first airbag 10 and the second airbag 11 (rear airbag 4a) may be used to stretch the back K, and the third airbag 14 and the fourth airbag 15 (front airbag 4b) may be used to stretch the buttocks D. <The left and right airbags inflate alternately> Also, the first airbag 10 and the third airbag 14 disposed on the right side of the main body 5 constituting the seat 3 are inflated. Alternate inflation and deflation control may be performed so that the second airbag 11 and the fourth airbag 15 disposed on the left side of the main body 5 begin to inflate at the same time as the airbags 10 and 14 are deflated.

[0117] Specifically, when the first airbag 10 is inflated, the right side of the back K of the user U lying on his / her back on the main body 5 is lifted, and when the third airbag 14 is inflated, the right side of the buttocks D of the user U is lifted, thereby reducing stress on the right side of the back K and buttocks D. A tch exercise is carried out.

[0118] Next, the airbags 10 and 14 are deflated, and the second airbag 11 is inflated, thereby lifting the left side of the back K of the user U, and the fourth airbag 15 is inflated, thereby lifting the left side of the buttocks D of the user U, thereby performing a stretching exercise for the left side of the back K and buttocks D.

[0119] In other words, the first airbag 10 and the third airbag 14 on the right side may be used to stretch the back K and buttocks D on the right side, and the second airbag 11 and the fourth airbag 15 on the left side may be used to stretch the back K and buttocks D on the left side. <Airbags inflate alternately in the cross direction> Also, the first airbag 10 on the right rear side and the fourth airbag 15 on the left front side, which are arranged in a cross direction in the main body 5 that constitutes the seat 3, are inflated. Alternate inflation and deflation control may be performed so that the second airbag 11 on the left rear side and the third airbag 14 on the right front side, which are arranged in the opposite cross direction, begin to inflate at the same time as the airbags 10, 15 are deflated.

[0120] Specifically, when the first airbag 10 inflates, the right side of the back K of the user U lying on his back on the main body 5 is lifted, and when the fourth airbag 15 inflates, the left side of the buttocks D of the user U is lifted, thereby performing a stretching exercise for the right side of the back K and the left side of the buttocks D.

[0121] Next, the airbags 10 and 15 are deflated, and the second airbag 11 is inflated, thereby lifting the left side of the back K of the user U, and the third airbag 14 is inflated, thereby lifting the right side of the buttocks D of the user U, thereby performing a stretching exercise for the left side of the back K and the right side of the buttocks D.

[0122] In other words, the first airbag 10 and the fourth airbag 15, which are arranged in a cross direction, may be used to stretch the right side of the back K and the left side of the buttocks D, and the second airbag 11 and the third airbag 14 may be used to stretch the left side of the back K and the right side of the buttocks D.

[0123] In this way, the desired stretching effect can be achieved by alternately inflating and deflating the predetermined airbags 10, 11, 14, and 15. The timing of inflation and deflation of each airbag 10, 11, 14, and 15 can also be individually controlled to be delayed or advanced.

The third airbag 14 is in contact with the right calf CR, and the fourth airbag 15 is in contact with the left calf CL.

[0130] The first extension part 6 is wrapped around the outer periphery of the right thigh part TR, and the second extension part 7 is wrapped around the outer periphery of the left thigh part TL, and the first extension part 6 and the second extension part 7 are fastened together with the buckle member 21. This secures the right thigh part TR and the left thigh part TL (leg part L) in place, and they are stabilized on the main body part 5.

[0131] The first airbag 10 and the fifth airbag 20 are in contact with the right thigh region TR, and the second airbag 11 and the sixth airbag 22 are in contact with the left thigh region TL. That is, the fifth airbag 20 is deployed in a position facing the first airbag 10 across the right thigh region TR. The sixth airbag 22 is deployed in a position facing the second airbag 11 across the left thigh region TL.

[0132] Here, a description will be given of the inflation and deflation of the first airbag 10 to the sixth airbag 22 in "Treatment 2." In this embodiment, the first airbag 10 to the sixth airbag 22 are configured to be capable of inflating and deflation independently and alternately. <Front and rear airbags inflate alternately> For example, the first airbag 10 and the fifth airbag 20, and the second airbag 11 and the sixth airbag 22, which are arranged on the rear side (pillow part 2 side) of the main body 5 constituting the seat part 3, are inflated. Alternate inflation and deflation control may be performed so that the third airbag 14 and the fourth airbag 15, which are arranged on the front side of the main body 5, begin to inflate at the same time as the airbags 10, 11, 20, 22 are deflated.

The belt fastening member 26 is provided with belt holes 27 through which the belt member 25 can be passed in the left-to-right direction. A plurality of belt holes 27 are provided on the front and back, allowing the position of the belt member 25 in the front-to-rear direction to be adjusted.

[0155] Specifically, the belt fastening member 26 is attached to the back surface of the main body 5 by sewing its front and rear edges in the left-right (width) direction, and its longitudinal midpoint is attached to the back surface of the main body 5 by sewing in the left-right direction. In other words, the belt fastening member 26 is attached to the back surface of the main body 5 by sewing it at four equally spaced locations in the front-to-rear direction. A space 27 penetrating in the left-to-right direction is formed between the sewn portions. This space 27 is the belt hole 27 mentioned above. The size of this belt hole 27 is smaller than the wide portion of the belt member 25 and larger than the narrowed portion (midpoint in the longitudinal direction). Because the wide portion of the belt member 25 is larger than the belt hole 27, the belt member 25 will not fall off the belt fastening member 26 when worn on the main body 5.

[0156] The belt holes 27 are provided in a plurality so as to be aligned at equal intervals in the front-rear direction of the belt fastening member 26. In this embodiment, the belt fastening member 26 is sewn to the back surface of the main body 5 so as to have three belt holes 27a to 27c in the front-rear direction. The front-rear position of the belt member 25 on the main body 5 can be adjusted by passing the belt member 25 through any of the belt holes 27a to 27c. This makes it possible to change the wrapping positions of the first extension portion 6 and the second extension portion 7 relative to the treatment area. The number of belt holes 27 is not limited to that exemplified, and may be two or four, and is not limited to any particular number.

[0157] As shown in FIG. 5B, for example, the wide portion of the belt member 25 (the first extension portion 6 or the second extension portion 7) is bent so that it is smaller than the belt hole 27b, and the belt member 25 is passed through the belt hole 27b. When the belt member 25 reaches the narrowed portion (the midway portion in the longitudinal direction), the first extension portion 6 and the second extension portion 7 protrude from the left and right sides of the main body portion 5, so the belt member 25 is then unfolded. Because the wide portion of the belt member 25 is larger than the belt hole 27b, the belt member 25 will not fall off the main body portion 5 (belt fastening member 26). The belt member 25 may be passed through either the belt hole 27a or the belt hole 27c.

[0158] By doing so, the position of the belt member 25 in the front-rear direction is determined, and the belt member 25 is attached to the main body portion 5. Then, the first extension portion 6 and the second extension portion 7 are wound around the area to be treated of the user U placed on the main body portion 5, and the buckle member 21 is fixed.

[0159] In addition, the belt member 25 can be removed from the main body 5 by pulling it out of the belt hole 27b (belt fastening member 26), which is convenient when changing the position of the belt member 25 or storing the air stretch exercise device 1.

[0160] FIG. 5C schematically shows a modified example of the second embodiment of the air stretching exercise device 1 according to the present invention.

[0161] As shown in Fig. 5C, in this modification, a hook-and-loop fastener 21 is used as the engaging member 21. The other configurations of this modification are substantially the same as those of the second embodiment described above.

[0162] In this modification, one side of a hook-and-loop fastener 21 is provided on the tip side of the first extension portion 6. The other side of the hook-and-loop fastener 21 is provided on the tip side of the second extension portion 7.

[0163] The first extension part 6 is wrapped around the outer periphery of the right calf CR, and the second extension part 7 is wrapped around the outer periphery of the left calf CL, and one end of the hook-and-loop fasteners 21 provided at the tip of each extension part 6, 7 is engaged with the other end to fix the hook-and-loop fasteners 21. This allows the right calf CR and the left calf CL to be stable on the main body part 5.

[0164] An engaging member 28 is provided at the center of the front edge of the main body part 5 (seat part 3). In this modified example, a hook-and-loop fastener 21 is used as the engaging member 28. The main body part 5 is wrapped around the outer periphery of the pillow part 2 and engaged with the hook-and-loop fastener 21 to prevent the main body part 5 from unraveling. In other words, the sheet part 3 (main body part 5) is configured to be able to be wound in a roll toward the pillow part 2 side.

[0165] In this way, by winding the main body 5 into a roll and engaging it with hook-and-loop fasteners 21 or the like, the air stretch exercise device 1 becomes compact and easy to carry. It also requires less storage space. Furthermore, by disengaging the hook-and-loop fasteners 21, the main body 5 can be released from the pillow 2, allowing the air stretch exercise device 1 to be easily laid out on the floor F or the like.

[0166] The air stretching exercise device 1 of the present invention is provided with a seat section 3 containing air bags 4 that can be used to treat various body parts. In addition to performing stretching exercises in which the air bags 4 are inflated and deflated to stretch and loosen treatment areas such as the back K and buttocks D of the user U while lying supine on the seat section 3 (main body section 5), the user can also perform pressure massage actions in which the air bags 4 (first air bag 10 to sixth air bag 22) are inflated and deflated to knead and loosen treatment areas such as the thighs T and calves C of the legs L while seated on the main body section 5 with the upper body B in an upright position.

[0167] Furthermore, the air stretch exercise device 1 of the present invention can be stored smoothly and compactly because the sheet portion 3 (main body portion 5) can be wound up into a roll. This configuration allows the user U to easily lay it out on the floor F or store it away. In other words, the air stretch exercise device 1 of the present invention is not limited to a specific installation location.

[0168] It should be noted that the embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive.

[0169] In particular, in the embodiments disclosed herein, matters not explicitly stated, such as operating conditions, operation conditions, component dimensions, and weights, are within the scope of ordinary skill in the art and are easily conceivable by those skilled in the art. For example, the configurations, such as the arrangement and shape of the first extension portion 6 and the second extension portion 7, can be appropriately changed in consideration of the treatment area. Similarly, the configurations, such as the arrangement and shape of the third extension portion 8 and the second extension portion 9, can be appropriately changed in consideration of the treatment area. Furthermore, the configurations, such as the arrangement and shape of the first airbag 10 to the sixth airbag 22 (airbag 4), the rhythm of inflation and deflation, and the order of inflation can be appropriately changed in consideration of the treatment area. The airbag 4 can be a single piece that fits within the main body 5. Alternatively, the airbag 4 can be provided without an upper cloth and placed on the top surface of the main body 5. The belt member 25 can be sewn to the main body 5, or, as described above, can be a separate member that can be attached and detached from the main body 5. [Explanation of symbols]
