Abstract

PROBLEM TO BE SOLVED: To provide a care chair which can perform shifting of all of postures of lying, floor sitting, chair seating and standing, by one machine, with one button switch.SOLUTION: A user having walking difficulty who is unable to support his/her body in bending a knee joint shifts forward of a hip body weight gravity center by forward horizontal shifting while a backrest 1, an armrest 2, and a horizontal bending seat plate 22 are lifted. A portion having moved forward of the bending seat plate is bent and suspended and an area of the seat plate is reduced sequentially. Immediately before the area is dissipated due to lifting of the bending seat plate and suspension of the bending seat plate, the knee joint is extended to form an upright standing posture. Reversely, when a back in a standing posture is placed against the backrest, a chair seating posture, a floor sitting posture, and a lying posture are freely changed with only an intention of the user himself/herself to enhance a self recovery desire. The mechanism can be mounted on a care chair and an automobile seat as well as a body rotation device to contribute to ensure safety of a care giver and a care receiver and to eliminate mind/body fatigue.SELECTED DRAWING: Figure 1-1

Description

  Including the aging of the human society, the sick, or rehabilitation, it will also diversify at the same time to promote mental stabilization of the weak, reduce the labor of caregivers, and raise the self-recovery self-consciousness of the old sick Contributes to versatility in the automobile society.

  The present invention is a modern society where there is an increase in the number of sick people due to the aging of humankind and the shortage of caregivers.In the home medical treatment promotion policy, the mental and physical stress between the sick and the caregivers can be eliminated, and the self-care Improving the gap between physical strength and emotion that does not follow consciousness, reducing the physical and mental exhaustion of the elderly in aged society and family life, preventing the sick people from recovering from healthy recovery, and tilting the buttock by tilting the seat plate called a nursing chair The purpose is to avoid an example of a fall accident.

Indication of invention

Problems to be solved by the invention

1. There are no commercially available safe care products that deal with all the differences in physical abilities of the sick.
2. The sick are incapable of self-behavior even if they have a willingness to stand on their feet or want to lie down on their seats and have no choice but to rely on caregivers.
3. Visiting care and rehabilitation walking training are not related to the physical condition of the weak, and there are time limits due to visiting care.
4. At last, sick people who can walk are unable to stand on their own and need nursing pedestals. At the same time, it is difficult to sit on a chair or sit on their own.
5. Most sick people tend to refrain from requesting care for all caregivers including family members for each self-consciousness, and physical recovery is difficult at the same time as the mental state of the weak falls.
6. Due to the modernization of the nuclear family, the increase in domestic medical treatment due to the national policy is due to an increase in the elderly care environment, and both the caregiver and the cared person are severely mentally weakened between parents and children. Will also develop.
7. There are no commercially available care products for the sick person's own willingness to recover.
8. The weak who are eager to recover can be used as a weapon for the weak by using poorly functioning or poorly functioning care products, and life-related accidents still exist.
9. With the current situation of shortage of care personnel at care facilities, the caregiver's physical labor limit should be considered.
10. Healthy consciousness, physical disability, toilet operation in the toilet is self-independent as much as possible.
11. Day service pick-up car by a nursing facility, even if there is a hydraulic lift for wheelchairs, the number of people cannot be used, and seating on a normal passenger car is not easy to prevent injury.
12. Measures to improve car seats that are difficult to get on, not only for nursing-care vehicles, but also for private hospital visits and family support.

Means for solving the problem

1. In the daily life of the weak, the important issue of sitting and standing legs from lying down is to reduce the load on the waist, legs, muscles and joints during posture transition by moving the center of gravity, and reduce the burden on each part of the body and the body A mechanism that promotes increased willingness to recover.
2. The transition from a vertical standing state to a chair and floor, or floor recumbent must be balanced by weight transfer before joint flexion, and emphasis is placed on assisting in the inability to maintain weight during this position movement. about.
3. The transition from standing to sitting on the floor and sitting on the chair and moving from the standing position is the same, and assisting the vulnerable position.
4. Being able to control the posture freely and self-consciously, it is possible to continue stillness at the desired position, from the side to the floor, from the floor to the stance, and vice versa.
5. To that end, the transition from standing to sitting / flooring, lying down is almost vertical, if the back and buttocks of the weak are held on a chair, the vertical backrest The armrests are kept in a vertical state, the seat plate descends to form a horizontal seat plate, the area expands, the chair seat shifts to the floor seat posture, and the backrest plate is turned upside down and finally becomes a recumbent posture In addition, the final seating by increasing the inclination angle of the seat plate should be prohibited due to sliding down on the weak leg.
6. The stance transition from the recumbent posture, the floor-sitting posture, or the chair-sitting posture allows the stance to be made naturally, so that the horizontal seat plate is observed to the last in the reverse process of the previous section 5.
7. Because it is necessary to promote the rehabilitation motivation by the physical limitations of the weak, it is possible to repeat the self-rehabilitation by freely stopping the seat at the limit position of the physical strength.
8. With a human-powered wheelchair installed, self-motivated safe ride-off movement behavior is liberalized, and sometimes on-the-car normalization is possible, to respond to changes in health and to improve body motivation.
9. The same applies to wearing an electric wheelchair, and it is possible to sit in a narrow seat and shift to a posture according to the physical condition to enable safe and easy seating and recumbent body rest.
10. The passenger car seat should be equipped with this function. The chair can be rotated by opening the door, seated on the side of the car, self-sitting, rotating in the specified direction, and lying down in the office depending on the physical condition of the weak.
11. The holding stance legs are not only for nursing care but also for the physical consumption of the weak, and to reduce the mental and physical burden of caregivers and care recipients.

Effect of the invention

1. In the daily life of the weak, with a single switch, the willingness to act on the side, the floor, the chair, and the stance is always free and safe for each self-motivation without hesitating the caregiver. The physical and mental debilitating exhaustion of caregivers and care recipients is reduced.
2. Even sick people who are difficult to maintain rehabilitation will not need daily life such as refraining from caregivers, constantly thinking about the feelings of others, leading to self-motivation.
3. The caregiver's assistance to the weak is due to the physical fatigue that supports the weight of the weak with the lower back, especially the unstable and narrow wheelchair seats, and the sitting legs when moving to a hospital car, etc. Both care recipients are at risk, but the care effort is reduced and safe to the extent that they hold their hands.
4. Contribute greatly to the social phenomenon of shortage of caregivers and to the modern society where the number of vulnerable people increases due to aging acceleration.
5. Importantly, there are cases in which the vulnerable people who are cared for constantly take care of third parties including caregivers, consciously suppress drinking food in order to avoid large and small constipation, and the condition cannot be recovered. To be able to operate the toilet alone as much as possible.
6. Installed in a car for the caregiver, the door is opened, the seat is rotated, and the back is placed on the back, so that the caregiver is not required to sit safely. The caregiver can reduce labor by holding the hand of the weak.
7. However, the caregiver is required to visually confirm and to join the hands from safety assistance, and will be dedicated to physical labor care only when necessary.

  The armrest (2) mounted on the left and right of the backrest (1) can be rotated and stored parallel to the edge of the backrest (1) when lying down. The mounting height of the armrest (2) varies depending on the posture of the user. The position can be changed by screw tightening or the like in the plurality of armrest mounting holes (3) according to the physical condition, and the position is set according to the body shape.

  The inclination angle of the backrest (1) can be shifted in the range of 90 degrees or more from the horizontal position, and sometimes it can be an extendable backrest (1), and the backrest inclination gear for adjusting the inclination of the backrest (1) (4) is fixedly mounted on the lower part of the back of the backrest (1), but it may be mounted on both the left and right sides of the backrest (1) and at one place in the center.

  The most important thing in the transition from the sitting position to the standing position is the armrest (2) whose height can be changed by selecting an armrest mounting hole (3) integrated with the backrest (1), and a bent seat (22) described later. ) Is lifted together with the upper rail (5), while the backrest (1) and the refracting seat plate (22) are advanced according to the degree of ascent, and are moved forward while maintaining the sitting position. Gravity applied to the body is not much different from that at the time of sitting, the legs do not leave the floor, and the leg weight load is eliminated and the safety stance is completed until the leg knee joint extends to the standing position.

  The most important thing when this stance is transferred is that the conventional common sense nursing chair seat tilt can be used for the weak who are difficult to hold the leg weight when flexing the knee joint, despite the care chair intended for use by the weak leg. By tilting the seat plate, there is no flexion knee joint native enough to support the movement of the buttock weight, but it may change to a weapon that falls down the buttock and bruises in the head bruise. Maintenance is the most important issue. The bent seat (22) is integrated with the backrest (1) and moves forward horizontally. Every time the weight is moved forward, the remaining seat remains horizontal and the surplus seat is bent each time. The mechanism is designed to reduce the seat plate area by shifting, and in order to cope with these, the upper rail (5) and the lower rail (6) are set.

  The cross-sectional shape of the upper rail (5) and the lower rail (6) may be the same shape or a shape that can function even if the cross-sectional shape is different. For example, both the upper rail (5) and the lower rail (6) In order to reduce weight, one side opening and the other three sides are made of aluminum channel bars (7) on the wall surface, and the opening side is inwardly symmetrical, and both the upper rail (5) and lower rail (6) are in front of the left and right rails. The part and the rear part are connected with aluminum angle steel bars to maintain a square shape.

  For raising and lowering and back and forth movement of the backrest (1) and the bent seat plate (22) to be described later, the front wheel of the moving vehicle (( 9) and the moving vehicle (11) by the moving vehicle rear wheel (10) are loaded, and the moving vehicle front wheel (9) mounted in the left and right channel hollow portions (8) includes the moving vehicle front wheel shaft (12) and the moving vehicle. The rear wheels (10) are respectively connected by the rear wheel axle (13) of the moving vehicle, and enable front-rear traveling at the same position on the left and right.

  The backrest (1) is connected to the left and right end portions of the front wheel shaft (12) of the moving vehicle in a rotatable state. When using a specific overweight person, pay attention to the shaft material and shaft diameter. The shaft position fixing frame (14) may be mounted by maintaining the distance between both shafts.

  The inclination transition of the backrest (1) is fixed by the engagement between the backrest inclination gear (4) and the backrest drive gear (16) mounted to the backrest inclination drive machine (15), and the upper rail (5) is moved back and forth. In addition, the back tilt drive unit (15) is mounted so that it does not interfere with the horizontal movement of the recumbent body position (1) across the two axes of the moving vehicle front wheel shaft (12) and the moving vehicle rear wheel shaft (13). Is also necessary, and pay attention to the total strength of the two axes.

  The upper rail (5) not only moves vertically, but the chair seat body weight center is located behind the contact position between the floor and the feet, and the front weight movement at the time of standing is indispensable. In order to faithfully protect the seat, the front part of the seat must be kept in a horizontal position, and it is impossible to stand by fixing the area of the seat while the chair is seated. There is a risk of sliding down, and importantly, the center of gravity position of the buttocks does not change, and the seat plate horizontal transition is only the bent seat plate (22).

  The back and forth movement of the armrest (2) and the bent seat (22) including the backrest (1) that operates in conjunction with the rise of the upper rail (5) is due to the lifting rod (17) installed on the left and right objects.

  The elevating bar (17) may be two plate-shaped or square bars that are lightweight and retain strength, and sometimes round bars, but in the present invention, a rectangular tube having a rectangular cross section is used to maintain bending strength in the vertical and horizontal directions.

  Two lifting rods (17) having the same length of square tube are stacked, and are attached through the lifting rod center pin (18) in a rotatable state with the center in the length direction as a center point.

  For mounting the left and right lifting rods (17) joined by the lifting rod center pin (18) to the upper and lower front ends of the left and right rails of the upper rail (5) and the lower rail (6), the upper rail (5) and the lower rail (6 Both the front ends of) are mounted in a rotatable state by the lifting bar position fixing pin (19).

  The upper rear ends of the left and right lifting rods (17) intersecting at the center of the lifting rod center pin (18) are connected to either the rear wheel (10) or the front wheel (9) of the upper rail (5), A lifting rod tip wheel (20) is mounted on the lifting rod (17) at the rear end and is loaded on the lower rail (6).

  The function of the elevating bar (17) is loaded into the upper rail (5) and the lower rail (6), and the elevating bar position fixing pin ((19) and rear end part of the front end of the crossed elevating bar (17) are By moving horizontally by the moving wheel, the moving motion (11) of the upper rail (5) is automatically moved back and forth along with the up-and-down movement of the upper rail (5).

  On the front of the backrest (1) mounted on the upper rail (5), a plurality of plates (21) laid horizontally on the left and right upper rails (5) can be bent vertically 90 degrees downward. The bent seat plate (22) is configured by being joined by a joint, and the joint with the backrest (1) of the bent seat plate (22) is also joined and integrated in a bendable state.

  The load strength of the bent seat plate (22) is set to a plate thickness in consideration of safety capable of withstanding the buttocks seating weight.

  The multiple seats of the bent seat (22) are joined with a constant gap while avoiding tight joints. In the case of tight joints, the corners on the upper surface of the board are cut at a constant angle, and when the seat is moved from a standing leg to a chair. This prevents the hip and thigh meat from being pinched when seated due to the horizontal shift of the bent seat plate (22) that can occur at the front end of the head.

  The utility of the bent seat (22) is very important. When standing from a normal chair for a healthy person, the knee joint inner angle is unconsciously drawn to about 75 degrees, and the buttocks are moved forward to correct the weight. On top, put your palm on your knees and put your arms into the arms, finally lean forward and move the center of gravity to the front, and you can extend the knee joint and waist to stand up, but any healthy person can still sit There is no reason to be able to stand up with knee joints and hips stretched out.

  By faithfully applying the ergonomics theory of healthy subjects in the previous section, it covers all the inability to shift the self-position of any weak person, and the present invention is theoretically safe for sitting and standing of the weak in knee joint and lumbar disease To help.

  The most important thing is that while the upper rail (5) is raised, the backrest (1) and the bent seat plate (22) are moved to the front end while being horizontal, so that the stability is maintained throughout the standing stage. The bent seat plate (22) is important, and when the bent seat plate (22) for horizontal maintenance advances, the portion beyond the front end of the upper rail (5) automatically bends and hangs down due to gravity, and gradually becomes the horizontal maintenance state area. The knee leg and lumbar part gradually expand, and the position of the chief subjects advances each time, and it is possible to stand on the extended knee joint by automatic transfer. Finally, the backrest (1) and the bent seat (22 ) Makes it possible to support the stance safely in both vertical planes.

  When the stance is completed, the physical and mental needs of the weak who are difficult to maintain a non-contact stance standing upright, unlike normal subjects, often need to maintain some contact position, which is important not only for sitting but also for standing. The armrest mounting hole (3) that can change the position of the armrest (2) is also effective.

  On the contrary, the transition from the standing position to the chair sitting or the floor sitting or to the lying position is always horizontal if the weak person's back is left behind on the vertical backrest (1) and the bent seat (22). The bent seat (22) automatically and safely achieves its purpose without the need for weight maintenance in difficult leg joint flexion.

  Depending on the physical condition of the weak, it is natural to extend the toes in the floor sitting position and the recumbent body position, but there is also a desire for kneeling in the recumbent body position. The calf board (23) is mounted with a bent joint, and the calf board (23) has the same thickness as the combined height of the upper rail (5) and lower rail (6) in order to maintain the horizontal position of the legs in the seated or lying position. And smooth the horizontal movement by installing a slipper on the left and right of the tip.

  When a weak person wants a knee stand, and when he wants a knee stand automatically by electric power, a knee stand driving machine (24) is attached to the center or left and right of the connection part of the left and right rails of the upper rail (5). Depending on the operation, a mechanism to push up the back side of the bent seat plate (22) at a certain height may be installed. When the property is not required, a cushion and a pillow may be inserted into the lower part of the joint between the bent seat (22) and the calf (23) to form a mountain shape.

  The lifting drive (25) for driving the lifting rod (17) is mounted on each of the left and right ends of the upper rail (5), one on each of the left and right ends of the lower rail (6), or one in the center. In some cases, the lifting and lowering drive (25) is mounted on the left and right of the lower rail (6).

  Conventional similar lifts using cylinders such as hydraulic pressure, water pressure, pressure gas, etc. can be used, but it is not just a lift, but an automatic back and forth movement function is essential at the same time as the lift.

  The elevating drive (25) is equipped with an electric motor speed reduction gear head to increase torque, and sometimes is an officer drive with a speed controller, but there is also a manual angle bar rotation by a caregiver.

  One end of the spiral cutting rod type spiral shaft (26) is connected to the rotary output shaft of the lifting drive (25) via a universal joint, chain coupling, loose coupling, or the like, but sometimes directly coupled Sometimes.

  The length of the spiral shaft (26) is raised and lowered from the lifting drive (25) at the maximum rising point of the upper rail (5) intersecting with the lifting rod central pin (18) of the lifting rod (17) as the center point. The length is longer than the rod tip ring (20).

  On the axle of the lifting rod tip wheel (20), a spiral bearing (27) for processing a spiral hole that matches the screw hole of the spiral shaft (26) is mounted, the spiral shaft (26) penetrates, and the spiral shaft (26). The lifting / lowering rod tip wheel (20) moves horizontally back and forth by rotating left and right.

  At the farthest tip portion of the spiral shaft (26), an idler bearing (28) that rotates in a fixed position corresponding to a change in the horizontal movement torque due to the lifting and lowering of the load of the lifting rod (17) is mounted. Thus, the longitudinal movement during the rotation of the helical shaft (26) is absorbed by being idled at the leading edge.

  When each drive device such as a lift drive (25) is electric, all controls are performed by the switch box (29), but it stops when the hand is released with a button switch to ensure safety for extremely weak people. Although the method is better, it may be a snap switch, a contact switch, or sometimes a voice instruction switch.

  The installation location of the switch box (29) may be fixed on the side of the armrest (2), etc. However, in order to avoid erroneous contact operation from the weak physical condition, and considering the position of the recumbent body, it is possible to attach and detach the armrest. It can also be suspended.

  There are many cases where the main body rotating device (30) is necessary. For example, when a table meal is finished in the chair sitting position of a family group, in the case of a standing leg, it is always left or right or the rear, or the standing leg with the chair lowered to the rear. However, if the main body rotating device (30) is turned to the left or right or back, the stance can be made as it is.

  The main body rotating device (30) mounts the present invention on seats of various wheelchairs with small wheel diameters, electric cars, car for taking care of a car in a cared person's hospital, a car that is difficult for a normal person to sit on, etc. Therefore, weak people who cannot keep their weights flexed, such as knee joints, will be injured if they do not try to force them. Considering sociality, it becomes an important point not only for the main body rotation device but also for sitting and stadium hardness uniting.

  The reason why the grip support bar (31) may be installed partially or separately according to the present invention is that the armrest (2) after standing on the left and right is located on the left and right sides due to the difference in physical condition of the weak, so the location movement is forward walking However, the presence of the support bar (31) is grasped at a certain distance from the movable chair of all postures according to the present invention, and there is safety and stability of the weak feelings. By grasping this, the safety of the next walking action can be promoted. .

  Claim 2 is that the elevating drive (25) is a linear head motor (32) integrated with the moving vehicle (11) of the upper rail (5), and the reduction gear (34) in the linear head (33). With the vertical lifting power of the rack (36) meshed with the pinion gear (35) whose rotational torque has been increased by the above, the entire upper rail (5) mounted is pushed up directly from the floor, and the horizontal transition guide by the lifting rod (17) It is one end of various raising / lowering drive machines (25) which also has the back-and-forth movement of the bent seat plate (22) and the like.

  The rack (36) is moved up and down by meshing with the pinion gear (35), but the rack grounding part moves back and forth by the elevating rod (17) so that the rack ring (37) is provided at the lower end of the rack (36). Mount and move on the rack wheel rail (38).

  The weight on the bent seat (22) is supported by the rack (36), but the overall weight when the elevator is stopped is dispersedly supported by the elevator rod (17), and the helical shaft (26) according to claim 1 is supported. Unlike the full load support of the lifting rod (17) by rotation, the strength of the lifting rod can also be taken into account.

  The strength of the rack (36) is either a general-purpose product or a 150kg load-bearing product, and the backrest (1) is mounted on the lower center of the back, but sometimes one on each side is sometimes mounted.

  Claim 3 is a case where it is used for the physiological stool of the weak, and caregiver underwear and toilet seating are customary, but considering the removal of psychological shame of non-caregivers, bent seat A circular or polygonal opening hole is provided in the buttocks contact area of the plate (22), a stationary toilet (39) is installed on the floor below the bent seat plate (22), or a valve bag is installed in the bent seat plate (22) opening. If you are a weak person who can put on the toilet stool (40) and can put on and take off under her own clothes but cannot sit on the toilet seat, she can use herself alone and consider the emotions of the weak. The emotions are often unpredictable for healthy individuals, and the condition worsening as a result of refraining from drinking water in the evening due to shame during stool is a daily occurrence. The development staff is one nurse and one caregiver. The name was added to ensure safety and effectiveness from the standpoint of protecting the vulnerable.

  According to a fourth aspect of the present invention, it is desirable to mount the whole mechanism of the first aspect. However, the mounting on the wheelchair seat (41), which is normally operated by a caregiver, can be performed from the front of a narrow space due to the size of the left and right wheels. In the case of a weak person who can only get off and is difficult to walk, it is extremely difficult to maintain the position of the caregiver and the cared person when sitting on the stance, but only the main body rotation device (30) according to claim 1 is used. However, even when riding from a narrow wheelchair front, it is possible to sit and stand safely by just holding each other's hands, but if there are no obstacles on the left and right with small wheels, mounting the main body rotation device (30) It goes without saying that it is possible.

  Claim 5 is attached to an electric wheelchair seat (42) referred to as an electric car. The wheel diameter is small due to the effectiveness of electric driving power transmission, and the left and right sides of the seat are normally open, but the presence of a seat front handle shaft cover, etc. There are some narrow and narrow models, and it may be difficult for the weak leg common rider itself to be difficult.At the same time, it is necessary to consider the difficulty in maintaining the weight on the bent knee in the sitting posture after riding, etc. It is common sense to respond to frequent physical changes in the elderly and the sick, and functioning in any situation is the essence of nursing care assistance. The development conditions of the present invention are as follows, and all items have been solved.

1. Electric wheelchairs have small front / rear and left / right wheels due to the drive torque, and the left and right seats are open to the narrow front floor with steps, riding from the front or from the side. However, it is very difficult for some weak people to get on the vehicle floor with their toes and toes raised. In order to avoid the risk of falling by stepping down the vehicle floor, it is necessary to make it possible to sit automatically on the floor outside the vehicle or on the ground, and when riding, with the vehicle external leg.
2. As long as it is used by people who are difficult to walk or who are difficult to maintain an upright posture, etc., except for those who require heavy care by full-scale caregiver labor, the most important is the transition from a standing posture to a sitting posture, or assistance from a sitting posture to a standing posture. `` Necessary mechanism '', the reason why the seat plate must be kept horizontal at any stage of transition is that the seated weight of the weak leg is always in the buttocks and thighs on the horizontal seat plate, except when the final vertical stance is completed In response to vertical load, the body load on the vertical leg is close to zero, and this load bearing point does not change to the level of standing upright.
3. Absolute prohibition is to joint the common fixed horizontal plate and vertical backrest, forcibly raise the back of the back and back using the front end of the seat as a fulcrum. This is a conventional stance system in which the heel is gradually inclined to make the hips slide down to make the leg weak incapable of being seated and forcibly stand up to be removed from the chair.
4. It is a well-known fact that this seat plate tilting mechanism becomes a weapon, and the weak are unable to follow the forced posture change during sitting and standing, and the weak who do not have the ability to hold the refractive leg in the mid-stand posture In many cases, it is possible to easily think that it would change into a weapon if one makes a mistake, even though there are examples of buttock sliding, falling falling, and bleeding in the head bruise due to the inclination of the seat plate, but it prevents misleading to those with weak knowledge. There must be.
5. The importance of maintaining the horizontal position of the seat plate in any position change process as described in the previous paragraph is that the seat plate area is reduced with the forward shift of the center of weight that moves parallel to the seat plate rise in either the standing leg or the seat transition process. Or, area restoration is essential, and it is the most important mechanism for maintaining the safety of the vulnerable.
6. Armrests are necessary to prevent the vehicle from falling from the left or right even if it is worn as long as it does not interfere with the driving of the electric car, maintains the posture during driving, and sometimes faints during driving.
7. The backrest can be tilted to some degree when leaning from the seated position, and the back can be pushed forward slightly. If you feel bad during riding, When taking a break in a park, etc., it is possible to change the position of the backrest on the vehicle, and it is possible to freely select from the sitting position to the recumbent position. Armrests are indispensable to prevent falling aside.
8. In the process of mutual transition between sitting and standing legs, the functionality that causes the weak person's willingness to recover health is also important, and it is a mechanism that allows repeatable rehabilitation from any position and enables the weak person's own willingness to recover.
9. Various driving devices that can cover all the mechanisms of claim 1 without limiting the type of driving power of each mechanism, and the mechanism according to the vehicle type is set to be simple is best.

  Claim 6 is a day care service transfer at a nursing facility, a passenger car for a vulnerable person, a passenger car for a vulnerable family member, etc., or, as is well known, if a normal passenger car has a low vehicle height, not only the weak but also a healthy person may depend on the vehicle type. May be difficult to sit on, the door is fully open, the body rotating device (30) is operated to face the vehicle side, the seat plate is raised and the backrest (1) and the bent seat plate (22) become vertical, If you turn your back to the backrest (1), you will automatically be in a seated position, turned to a regular seat by the main body rotating device (30), and sometimes in a recumbent position in the car, If it is installed as 43), it will be changed from a safe ride for the weak to a caregiver's labor, and at the same time a passenger car with characteristics that are also effective for the healthy person, making it possible to make the future seating behavior of passenger cars safe and simple.
