【0008】Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination of two cylindrical and mat-shaped air bladders to obtain a free back angle on a chair or the like, The present invention relates to a tool for supporting a waist, a tail skeleton, and the like hitting the edge of a seat when laid down with a cushion. 2. Description of the Related Art Conventionally, (a) a corner cushion including air or sponge, which is placed at a corner where a backrest of a chair or the like intersects with a seat, has a triangular shape, or has the same shape and has a long side concave in an arc shape. There was. (B) There was a cushion / cushion with air or sponge, which was placed at the corner where the backrest of the chair and the seat intersect with the seat, and a bulge was attached to the back side to fill the corner. (C) There was a waist cushion for a vehicle seat made of a columnar resilient body. (D) There was an air cushion that could be divided into a number of air chambers placed on the back and the seat of the seat, each of which could change the volume according to the body. However, in each case, the angle of the backrest is limited, the reclining function is not fully exhibited, and when sleeping, there is no function to prevent the waist, tail bone, etc. from directly hitting the edge of the seat when shifting the waist forward. Was. [0003] The present invention, except for its disadvantages, provides: A reclining function that can freely adjust the angle of the backrest on a chair or the like is obtained. 2 . When lying down, the waist, tail bone, etc. do not directly hit the edge of the seat. The purpose of this invention is to develop a free-back device having the above functions. Means for solving the problems will now be described. (A) An adhesive cloth (4) is provided on a cylindrical air bag (1) and an air cushion (2), and the two are overlapped. Linking·
The structure shall be separable. (B) Air bag (1) and air cushion (2)
A mesh-like cloth or the like is provided on the surface of the body so as to have air permeability when the body comes into contact with the body. (C) Air bag (1) and air cushion (2)
Is provided with an air valve (5). (D) The air bag (1) filled with air is placed sideways along the corner where the back of the chair intersects with the seat, and the air cushion (2) is laid thereon. , Freely adjust the angle of the backrest and connect. A free back device configured as described above. Further, the present invention provides (a) an air mat (3) provided with an adhesive cloth (4) so as to be connectable and separable from the air cushion (2). (B) Provide a non-slip at the bottom of the air mat (3). (C) While thickening one end of the air mat (3), and making the thick portion filled with air adhere to the front end of the seat,
By laying so that it protrudes, when the body is laid down, the waist and tail bones hitting the edge of the seat do not move back and forth, but are supported by the cushion. (D) A mesh-like cloth or the like is provided on the surface of the air mat (3) so as to have air permeability when the body is brought into contact. (E) An air valve (5) is provided on the air mat (3). An object of the present invention is to provide a free-back device configured as described above. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described. (A) When leaning on a chair: A cylindrical air bag (1) filled with air is provided with a seat back and a seat. Lay it down along the intersecting corner, lay the air cushion (2) on it, adjust the angle of the backrest properly according to the degree of air supply and the degree of lapping, connect and lean on it. As a result, since the cylindrical air bag (1) has a circular cross section, it deforms according to the shape of the contacting surface, and first fills a large space. The air cushion (2) is superposed thereon, so that the weight applied to the back can be evenly supported by air pressure over a wide area. (B) When sleeping on a chair: lower the stacking angle than in (a), bleed air, and adjust the sinking of the body.
Furthermore, the air mat (3) is filled with air, and while the thick end is in close contact with the front end of the seat, the air mat (3) is laid out so as to protrude, and is connected to the air cushion (2) so that it does not shift back and forth. Put your waist and tail bone on it and sleep. As a result, the same result as (a) can be obtained in a state where the body is turned down without the waist, the tail bone, etc. directly hitting the end of the seat. (C) When lying on a chaise lounge: air bag (1)
Lay it down under the armchair of the chaise lounge, place the air cushion (2) on it, adjust the angle of inclination freely according to the overlapping angle and the degree of air entry, connect the shoulder, Put your neck on. As a result, since the cylindrical air bag (1) has a circular cross section, it deforms according to the shape of the contacting surface, and first fills a large space. in addition,
The air cushion (2) is superposed, so that the weight applied to the shoulder, neck, etc. is large, and is evenly supported by air pressure. (D) When storing, the whole air may be evacuated and rolled. Use as above. In addition, there is a method of combining the air cushion (2) and the air mat (3) and using the mat as an elongated mat. There is also a method of combining the air bag (1) and the air mat (3) and using it as a waist pad. In addition, the air bag (1), the air cushion (2), and the air mat (3) can be variously used as a single unit, for example, by leaning the air bag (1) vertically and leaning against the corner of the armrest of the chair. There is also a method in which a free-deformable material such as a gel-like substance is used instead of air to fill the air bag (1), the air cushion (2), and the air mat (3). is there. The cylindrical shape according to the first aspect includes all shapes that can be freely deformed, such as those having an elliptical cross section and those having both ends rounded into a mountain shape. According to the present invention, If there is something that supports the back, such as the back of a chair, a wall surface, etc., the desired backrest angle can be obtained on the seat. 2. Since the wide contact surface of the body is supported with even air pressure, it is less tiring. 3. When sleeping in a seat, the waist, tail bone, etc., do not directly hit the edge of the seat, and are less likely to be tired. 4. When lying down on a chaise lounge, the shoulders, neck, etc. are supported by pneumatic pressure on a wide contact surface, making it less tiring. 5. Does not damage the furniture used. 6. Easy to carry. [0008]
