Description

The present invention relates to a chair-type massager having a seat and a backrest, and more particularly to a chair-type massager capable of stretching in addition to massage.

In addition to applying a medical treatment tool to the human body to massage the chair-type massage machine, it has been proposed to take advantage of having a seat and a backrest so that the body can be stretched.

Examples of chair-type massage machines capable of stretching include those disclosed in Patent Documents 1, 2 and 3 below.

The chair-type massage machine of Patent Document 1 is one in which the footrest is lowered while holding the leg by the footrest provided at the front end of the seat portion so that the leg can be stretched.

Although this chair-type massage machine has a stretching effect on the legs, it cannot stretch on other parts, especially the waist.

In this respect, there is a chair-type massage machine of Patent Document 2 that allows stretching to the whole body. This chair-type massage machine is configured so that the backrest is tilted backward to lift the footrest and then lower the footrest. The footrest is equipped with a gripping means for gripping the part of the leg below the knee, and the part below the knee of the human body that is bent on its back with the leg extended is fixed by the gripping means and the footrest is lowered. It rotates and pulls down. It is said that this makes it possible to stretch the whole body.

However, the human body is lying on its back, pulling is the part below the knee, and the leg bends around the knee, so the part that extends even if pulled is slightly above the knee and below, and above the leg. In other words, only the anterior muscle.

For this reason, the stretching effect is only on the part of the leg centered on the knee.

A chair-type massage machine capable of stretching the whole body is also disclosed in Patent Document 3 below. This chair-type massage machine does not tilt the backrest in advance as in Patent Document 2, but utilizes a reclining mechanism of the backrest that is provided so as to be able to rotate around the rear end of the seat. It is configured so that it can be stretched.

That is, the leg airbag is inflated to restrain the legs of the human body, and the backrest is tilted in this state. With this configuration, the upper body of the human body falls backward with the part below the knees fixed, so the body stretches. Unlike the configuration of Patent Document 2, the entire upper body is tilted backwards, so it seems that the whole body can be stretched.

However, when the backrest is tilted backward, relative movement occurs between the backrest and the upper body as the backrest is tilted. In other words, the relationship is such that the upper body of the human body shifts downward relative to the backrest on the backrest that falls. Therefore, when the backrest is tilted, the upper body slides down without staying on the backrest. Therefore, the reclining motion itself cannot be effectively used for stretching. The state in which the body is stretched without muscle tension is when the reclining motion is completed, and this state is not much different from simply tilting the backrest and bending the body.

In addition, since the upper body is tilted only by tilting the backrest, only the upper body of the human body is tilted around the waist, and the abdominal muscles and iliopsoas muscles are easily stressed. For this reason, the part centered on the waist becomes tense, and it is not possible to stretch in a sufficiently relaxed state. It may put a burden on users who are weak.

In this way, it was not easy to stretch the whole body with a chair-type massage machine. In addition, there has never been a chair-type massage machine that allows stretching to the waist.

Japanese Patent No. 4031304 Japanese Unexamined Patent Publication No. 2005-160866 Japanese Unexamined Patent Publication No. 2005-152260

Therefore, the main object of the present invention is to enable effective stretching around the lumbar region and around this portion.

The means for this is a chair-type massage machine provided with a backrest that can stand and tilt behind the seat, and the seat is provided so as to be movable in the front-rear direction, and the seat can be moved forward. The backrest portion is configured to be tilted backward in synchronization with each other, and shoulder holding means for holding the shoulder portion of the human body are provided on both left and right sides of the backrest portion, and both shoulder portions of the human body are held by the shoulder holding means. This is a chair-type massage machine that enables a waist stretching operation in which the backrest is tilted backward while the backrest is in the same state.

In this configuration, when both shoulders of the human body are held by the shoulder holding means and the lumbar stretching operation is performed in which the backrest is tilted backward from the standing state, the upper body of the human body is supported by the backrest and falls backward. .. At this time, since the shoulder holding means holds the shoulder portion of the human body, it supports the upper body that tends to lower relative to the backrest portion, and stretches the human body as the backrest portion tilts. At this time, since the seat portion moves forward in synchronization with the inclination of the backrest portion, the waist portion and the portion centered on the waist portion are particularly stretched without extra tension. When the backrest is completely collapsed, a general stretch state centered on the waist can be obtained.

As described above, according to the present invention, the posture change and the weight shift of the human body due to the backward tilting of the backrest portion and the forward movement of the seat portion can be stretched around the lumbar region by using the shoulder holding means. Since it can be used effectively, it is possible to stretch around the waist, which was not possible before. Since the waist can be stretched, it is possible to stretch the whole body around the waist.

The seat portion 12 and the backrest portion 13 are connected by an interlocking mechanism, and as shown in FIG. 4, the seat portion 12 is configured to move forward and the backrest portion 13 to tilt backward in synchronization with each other. ing.

When the seat portion 12 moves forward, the footrest 16 pivotally supported by the front end portion of the seat portion 12 also moves forward. The rotation of the footrest 16 can be performed in a state where the backrest portion 13 is upright or in a tilted state. Further, the arm treatment portion 15a on the upper part of the armrest 15 is connected so as to be interlocked with the back-and-forth movement of the seat portion 12. That is, when the seat portion 12 moves forward, the arm treatment portion 15a moves backward.

In order to realize such a movement, the chair type massage machine 11 has the following structure. 5 and 6 show a schematic shape and internal structure of the chair-type massager 11 in a side view, FIG. 5 shows a standing state of the backrest portion 13, and FIG. 6 shows a tilted state of the backrest portion 13.

As shown in these figures, the chair-type massage machine 11 reciprocates in the front-rear direction while being supported by the base frame 41 constituting the base 14 and the seat portion 12 and supported by the base frame 41. A possible seat frame 21, a backrest frame 31 that constitutes the backrest portion 13 and is rotatably connected to the seat frame 21, an arm support 51 that supports the arm treatment portion 15a, and the footrest 16. It is equipped with a constituent footrest frame (not shown).

The base frame 41 is formed by assembling square steel pipes, and has two base members 42 on both left and right sides extending in the front-rear direction, and a plurality of base members 42 erected on the base members 42 at intervals. It has a vertical member 43.

The plurality of vertical members 43 are formed longer toward the front of the chair-type massager 11, and when the upper end positions of the plurality of vertical members 43 are connected by a straight line, the straight line is tilted at an appropriate angle lower toward the rear. It is arranged in. Seat rails 44 that movably support the seat frame 21 are fixed to the upper ends of the vertical members 43 on both the left and right sides. That is, the trajectory of the front-back movement of the seat portion 12 is tilted so as to be higher toward the front.

An arm rail 45 that movably supports the arm support 51 is supported outside the seat rail 44 in the left-right direction. The seat rail 44 and the arm rail 45 are parallel.

Specifically, a fixed convex portion 46 projecting outward in the left-right direction is provided at a position immediately below the seat rail 44, which is the upper end portion of the two vertical members 43 located in front of the vertical member 43. A support connecting rod 47 extending in the vertical direction is fixed to these fixed convex portions 46. The two support connecting rods 47 extend in a direction orthogonal to the seat rail 44 in a side view and are parallel to each other.

The length of these support connecting rods 47 is a length that protrudes above the upper end surface of the seat rail 44. The intermediate portion of the support connecting rod 47 in the longitudinal direction is connected by a connecting rod 48 extending in parallel with the seat rail 44, and the upper end is connected by the arm rail 45. That is, the arm rail 45 is formed so as to be separated and supported from the lateral side of the base frame 41, and is located on the lateral side of the seat rail 44 and higher than the seat rail 44. It is provided parallel to 44.

The arm treatment portion 15a is provided on such an arm rail 45 so as to be movable back and forth via the arm support 51. At this time, as shown in FIG. 7, the arm treatment portion 15a is provided so that the intermediate position of the arm treatment portion 15a in the left-right direction is located directly above or substantially directly above the arm rail 45.

On both the left and right sides of the seat frame 21, a pair of left and right sliders 22 that cover the seat rail 44 from above and move in the front-rear direction are provided. The slider 22 has a substantially inverted U shape in vertical cross section. These sliders 22 are connected to the left and right by a plurality of connecting members 23 extending in the left-right direction and are integrated.

The seat frame 21 has a configuration in which the sliders 22 on both the left and right sides are connected by the connecting member 23 as described above, and the seat rail 44 in which the left and right sliders 22 are fixed on the vertical members 43 on the left and right sides of the base frame 41. Although the seat frame 21 can be moved back and forth, the seat frame 21 is configured to restrain the seat rail 44 as shown in FIG. 7.

In addition to the slider 22 and the connecting member 23, the seat frame 21 includes a front end horizontal member 24 extending in the left-right direction at the upper end of the front end position, and an upright wall 25 that stands up on both the left and right sides and moves back and forth together with the seat frame 21. (See FIG. 7) and a frame-shaped support frame 26 provided at a position below the slider 22. The support frame 26 is also constructed by assembling a square steel pipe.

As shown in FIGS. 1 to 4, the upper surface portion of the seat frame 21 including the front end horizontal member 24 is expanded at positions corresponding to the upper and lower portions of the back side of the thigh in the legs of the human body. A contracting airbag 27 (upper thigh airbag 27a and lower thigh airbag 27b), a cushioning material (not shown), and the like are built in to obtain a comfortable seating surface. .. The airbag 27 is a medical treatment tool, and the upper thigh air bag 27a is provided separately on the left and right sides, and the lower thigh air bag 27b is provided on the left and right sides integrally. ..

On the inner side surface of the upright wall 25 in the left-right direction, a waist lateral airbag 28 is provided as a waist lateral holding means for massaging the outer surface of the thigh of the human body and sandwiching and holding the thigh of the human body. It is equipped.

A reclining telescopic mechanism 18a that moves the seat frame 21 back and forth along the seat rail 44 between the lower position of the intermediate portion in the longitudinal direction of the front end horizontal member 24 and the bottom portion of the base frame 41. Is provided so that it can rotate relative to each other. The reclining telescopic mechanism 18a expands and contracts, and moves the seat portion 12 forward during extension.

As shown in FIGS. 5 and 6, the backrest frame 31 has a connecting portion 32 protruding forward at the lower end. The connecting portion 32 is rotatably connected to a pivoting portion 29 provided at a position above the upper surface of the slider 22 at the rear end of the seat frame 21.

Further, in the backrest frame 31, behind (above) the pivoting portion 29, an upper connecting portion 33 projecting forward like the connecting portion 32 is formed, and the upper connecting portion 33 is the backrest. It is rotatably supported by a support rod 49 that can be tilted as the portion 13 is tilted upright. The lower end of the support rod 49 is pivotally supported by a vertical member 43 at the rear of the base frame 41.

Since it is supported in this way, the backrest frame 31 moves forward while being relatively displaced so that the lower end portion is submerged under the seat frame 21 as the seat frame 21 moves forward. Make a reclining operation.

A waist airbag 34 that expands and contracts as a treatment tool is provided at a portion of the backrest portion 13 corresponding to the waist of the human body. The waist airbag 34 is separately arranged on the left and right sides.

Further, the shoulder holding means for sandwiching and holding the shoulder portion of the human body is provided at the portion of the backrest portion 13 corresponding to the shoulders of the human body on both the left and right sides. The shoulder holding means is composed of a shoulder airbag 35 that expands and contracts as a treatment tool and a raised portion 36 that supports the shoulder airbag 35. A plurality of shoulder airbags 35 may be provided in a stack, and the length in the longitudinal direction may be set longer. This is because the shape holding force at the time of expansion is increased and the shoulder portion can be strongly supported.

In addition to the backrest portion 13, the seat frame 21 is provided with a conversion mechanism 17 that converts the forward movement of the seat 12 into the backward movement of the arm treatment portion 15a.

As shown in FIG. 8, the conversion mechanism 17 includes a tilting link 71 rotatably supported by the connecting rod 48 located at a position outside the seat rail 21 in the left-right direction, and the tilting link 71. It is composed of connecting links 72 and 73 rotatably connected to both ends of the above. Of the two connecting links 72 and 73, the one connecting the seat frame 21 to the slider 22 is the seat side connecting link 72, and the one connecting the arm treatment portion 15a to the arm support 51 is connected. The arm side connecting link 73.

The tip of the seat side connecting link 72 is rotatably connected to the outer surface of the lower end portion behind the slider 22. The tip of the arm-side connecting link 73 is rotatably connected to the lateral side surface of the arm support 51 in the left-right direction.

The conversion mechanism 17 is set so that the movement amount L2 of the arm support 51 is smaller than the movement amount L1 of the seat frame 21. The amount of movement is appropriately set so that the position of the arm of the human body can be maintained when the backrest portion 13 is tilted down.

As shown in FIGS. 2, 5, and 6, the arm rest 15 has a wall shape that conceals the lower portion of the seat portion 12 and the base frame 41, and the arm treatment portion 15a and this. It is composed of a main body portion 15b that supports.

As shown in FIG. 2, the arm treatment portion 15a has an opening 52 on the upper surface. The opening 52 has a size that allows the arm (forearm including the hand) to be completely accommodated, and the depth is set so that the arm can be sufficiently inserted. At the front end of the arm treatment portion 15a, a U-shaped obstruction wall 53 in a plan view is formed to close the front end. A plurality of arm airbags 54 for treating the arm are provided in the arm treatment unit 15a.

As shown in FIGS. 5 to 8, the footrest 16 is rotatable by the expansion and contraction of the footrest expansion / contraction mechanism 18b whose one end is rotatably connected to the lower end rear portion of the support frame 26 of the seat frame 21. .. The footrest expansion / contraction mechanism 18b rotates the footrest 16 in the vertical direction from a vertical posture to a horizontal posture. The vertical posture is a posture in which the legs of the human body are hung down, and the vertical posture here means a state including a substantially vertical state in addition to the vertical state. The horizontal posture is a posture in which the legs of the human body are extended horizontally, and the horizontal posture here means a state including a substantially horizontal state in addition to the horizontal state. When the footrest telescopic mechanism 18b is extended, the footrest 16 is in a horizontal posture, and when it is contracted, it is in a vertical posture.

The footrest 16 has a pair of left and right recesses 61 having a size that can completely accommodate a portion of the human body below the knee portion of the leg. The footrest 61 is composed of a plurality of footrest carriers 62 and 63 in the longitudinal direction, and it is well known that the footrest carriers 62 and 63 are separated from each other or brought close to each other so that the footrest 61 can be expanded and contracted in the longitudinal direction of the legs of the human body. It has a telescopic mechanism (not shown). In addition, each of the footrest carriers 62 and 63 is provided with leg holding means for massaging the legs of the human body as a treatment tool and holding the legs so as to sandwich them.

The leg holding means is composed of a leg airbag 64 that expands and contracts, and includes a leg side airbag 64a that expands so as to sandwich the left and right sides of the shin portion of the leg, and a foot side airbag 64b that expands so as to sandwich the left and right sides of the foot. It has a leg sole side airbag 64c that presses the calf portion and a foot sole airbag 64d that presses the sole of the foot.

The respective airbags 27, 28, 34, 35, 54, 64 and other treatment tools such as fir balls (not shown), the reclining telescopic mechanism 18a, the footrest telescopic mechanism 18b, and the footrest telescopic mechanism 18c are shown in FIG. As shown in the above, the operation is controlled by the control unit 91. The control unit 91 is composed of a microcomputer or the like, and according to the input from the operation panel 92, the air generating means 93 and the distributor 94 that distributes the air sent from the air generating means 93 based on the program stored in advance. The reclining telescopic mechanism 18a and the like are driven and controlled. The airbags 27a, 28, 34, 35, 54, 64a, 64b, and 64c, which are separately arranged on the left and right, are connected so as to be independently expanded and contracted. In addition to the program, the storage unit 95 stores necessary information such as angle information of each unit desired by the user.

The program may include, for example, an automatic course mode such as a course mode for massaging the whole body, a course mode for massaging only the upper body, a course mode for massaging only the lower body, and a point mode for massaging a part desired by the user. Massage mode. The lumbar stretch mode for performing the lumbar stretch operation is set to be incorporated in the automatic course mode or to be used independently like the point mode.

In the chair-type massage machine 11 configured as described above, the backrest portion 13 is in an upright state or in a state of being tilted backward at an appropriate angle, and each of the shoulder holding means, the waist lateral holding means, and the leg holding means is included. A desired massage is performed on each part of the human body with a treatment tool such as an airbag 27, 28, 34, 35, 54, 64. Then, in the lumbar stretch mode, stretching is performed as follows.

An example of the lumbar stretch mode will be described below.
FIG. 1 shows an example of the lumbar stretch mode. When the lumbar stretch operation is started during various massage modes or when the lumbar stretch mode is selected and the backrest portion 13 is not in the upright state, the control unit 91 first drives the reclining telescopic mechanism 18a to drive the backrest. The part 13 is erected to be in the pre-stored lumbar stretch mode initial state. At this time, the footrest 16 may be in a vertical posture as shown by a solid line or a horizontal posture as shown by a virtual line.

After a predetermined time from the initial state of the lumbar stretch mode, the control unit 91 inflates the shoulder airbag 35, sandwiches both shoulders of the human body from both the left and right sides, and holds them against the backrest portion 13. In the drawing, the inflated airbag is provided with horizontal parallel lines. The same applies hereinafter.

After being sandwiched by the shoulder airbag 35, the control unit 91 extends the reclining telescopic mechanism 18a to move the seat portion 12 forward and tilts the backrest portion 13 rearward. After the reclining expansion / contraction mechanism 18a is fully extended, the control unit 91 measures a predetermined time set in advance.

In this lumbar stretch mode, in addition to the shoulder airbag 35, at least one of the lateral waist airbag 28 or the leg airbag 64 is inflated to hold a portion of the human body below the lumbar region and pulled further downward. It may be set so that force works. Further, in the lumbar stretch mode, the waist airbag 34, the upper thigh airbag 27a, and the lower thigh airbag 27b can be inflated as needed.

FIG. 10 is an example of a waist stretch mode in which the backrest portion 13 is tilted and the footrest 16 is also moved to stretch the waist. The operation of the footrest 16 is to extend the footrest 16 and extend the legs of the human body in the horizontal direction.

First, the control unit 91 drives the reclining expansion / contraction mechanism 18a, the footrest expansion / contraction mechanism 18b, and the footrest expansion / contraction mechanism 18c when the backrest portion 13 and the footrest 16 are not in the pre-stored lumbar stretch mode initial state. Then, set the lumbar stretch mode to the initial state. In this case, the initial state of the lumbar stretch mode is a state in which the backrest portion 13 stands up, the footrest 16 is in a vertical posture, and the footrest 16 is contracted.

Next, after a predetermined time from the initial state of the lumbar stretch mode, the control unit 91 inflates the shoulder airbag 35 and the lumbar lateral airbag 28 as illustrated in the time chart of FIG. 11, and both shoulder portions of the human body. And hold the side of the waist. After that, the control unit 91 extends the footrest expansion / contraction mechanism 18b to rotate the footrest 16 upward. After a predetermined time slightly delayed from the start of extension of the footrest expansion / contraction mechanism 18b, the reclining expansion / contraction mechanism 18a is also extended to tilt the backrest portion 13.

Further, the leg airbag 64 starts to expand before a predetermined time when the footrest expansion / contraction mechanism 18b is fully extended. The predetermined time before the expansion / contraction mechanism 18b for the footrest is fully extended is the time required for the leg airbag 64 to expand.

Subsequently, after the footrest 16 is in the horizontal position, while the backrest portion 13 is still tilting, the telescopic mechanism 18c of the footrest 16 is driven to extend the footrest 16. With the footrest 16 extended in a horizontal position and the backrest portion 13 fully tilted, the control unit 91 clocks a predetermined time.

This lumbar stretch mode can also be performed without inflating the lumbar lateral airbag 28. It is also possible to inflate the waist airbag 34, the upper thigh air bag 27a, and the lower thigh air bag 27b as needed.

FIG. 12 is another example of the lumbar stretch mode in which the backrest portion 13 is tilted and the footrest 16 is also moved to stretch the lumbar region. The operation of the footrest 16 is to change the posture of the footrest 16 from the horizontal posture to the vertical posture and pull the leg of the human body downward.

First, the control unit 91 drives the reclining telescopic mechanism 18a, the footrest telescopic mechanism 18b, and the footrest telescopic mechanism 18c when the backrest portion 13 and the footrest 16 are not in the pre-stored waist stretch mode initial state. Then, the waist stretch mode is set to the initial state. In this case, the initial state of the lumbar stretch mode is a state in which the backrest portion 13 stands up, the footrest 16 is in a horizontal posture, and the footrest 16 is contracted.

Next, after a predetermined time from the initial state of the waist stretch mode, the control unit 91 inflates the shoulder airbag 35, the waist lateral airbag 28, and the leg airbag 64, as illustrated in the time chart of FIG. Both shoulders, hips, and legs of the human body are held at the corresponding positions of the chair-type massage machine 11.

After that, the control unit 91 extends the reclining telescopic mechanism 18a to move the seat portion 12 forward, tilts the backrest portion 13 backward, and at the same time contracts the footrest telescopic mechanism 18b. The start of the contraction operation of the footrest telescopic mechanism 18b may not be the same as the start of the operation of the reclining telescopic mechanism 18a, but may be delayed as appropriate. Then, the control unit 91 keeps the backrest portion 13 fully tilted and keeps the footrest 16 in the vertical posture, and measures a predetermined time set in advance.

This lumbar stretch mode can also be performed without inflating the lumbar lateral airbag 28. Further, if necessary, the waist airbag 34, the upper thigh air bag 27a, and the lower thigh air bag 27b may be inflated.

After the lumbar stretch operation in the lumbar stretch mode as described above, the control unit 91 shifts to the next operation of the preset automatic course mode, or ends the operation in a posture in which each unit is stored in advance.

In the lumbar stretching motion, the backrest portion 13 collapses, so that the upper body of the human body falls down as the backrest portion 13 tilts and lies on its back. At this time, since the shoulder portion of the human body is sandwiched and restrained on the backrest portion 13, the upper body that tends to be relatively lowered as the backrest portion 13 is tilted is supported.

Further, since the seat portion 12 moves forward as the backrest portion 13 tilts, the buttocks of the human body are pulled diagonally forward and upward according to the movement of the seat portion 12. Moreover, the backrest portion 13 does not fall backward with one point as a fulcrum when reclining, but is supported by two movable points, and falls down as the seat portion 12 moves forward.

For this reason, the waist portion of the human body and the portion centered on the waist portion are stretched in a state different from that of bending the body. This extension is performed in the process of tilting the backrest portion 13 and moving the seat portion 12 diagonally forward and upward, and also in a state where the backrest portion 13 is completely collapsed. Moreover, since the human body is stretched by interlocking the backrest portion 13 and the seat portion 12, the waist portion is stretched smoothly. In particular, since the seat portion 12 moves diagonally upward, the waist portion of the human body held by the shoulder airbag 35 is slightly lifted, and an unreasonable load is not applied to the human body.

Therefore, it does not bring extra tension to the lumbar region, and stretching of parts such as the iliopsoas muscle, which was not possible with conventional chair-type massage machines, is effective in a natural state without imposing a burden on the lumbar region of the human body. You can.

When the backrest is completely collapsed, a general stretch state centered on the waist can be obtained. With this stretch, you can relieve stiffness based on tension and heal tiredness.

In addition to such a stretching operation, the arm treatment portion 15a of the armrest 15 moves backward as the backrest portion 13 tilts, that is, moves forward of the seat portion 12, so that the position of the arm of the human body moves backward. It doesn't have to shift significantly. Therefore, it is possible to maintain a relaxed state of the whole body, and it is possible to stretch the whole body from the central part of the body called the waist part.

In particular, when the backrest portion 13 is tilted, when the waist side airbag 28 and the leg airbag 64 are inflated and the portion below the waist of the human body is positively fixed, the fixed state is obtained only by its own weight. , The stretching effect can be enhanced.

Furthermore, by adding the movement of the footrest 16, the legs and the portion connected to the legs can be actively stretched, so that the whole body can be stretched. By being able to stretch the legs and the like, stretching around the waist of the body becomes more effective.

Other examples will be described below. In this description, parts that are the same as or equivalent to the above configuration are designated by the same reference numerals, and detailed description thereof will be omitted.
As shown in FIG. 14, the shoulder airbag 35 may be manually or electrically movable along the longitudinal direction of the backrest portion 13.

When such a shoulder airbag 35 is provided, it is possible to cope with the difference in the physique of the user, and the shoulder airbag 35 can actively pull the human body in the extension direction.

The traction of the human body by the shoulder airbag 35 is performed in the above-mentioned lumbar stretching operation performed by tilting the backrest portion 13. That is, when the shoulder airbag 35 is raised as the backrest portion 13 is tilted, stronger stretching can be performed.

The traction of the human body by the shoulder airbag 35 can be performed independently of the stretch that tilts the backrest portion 13. That is, it is also possible to perform lumbar stretching or stretching centered on the upper body only by pulling. When stretching only by pulling motion, it is preferable to perform stretching with the backrest portion tilted down.
