Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harness-type child seat, in particular, to a clothes-type child seat, and more particularly, to a child's body, which can be freely and accurately attached to a child's body and can cope with sweating. The present invention relates to a dot type universal type harness type child seat.

[0002]

2. Description of the Related Art In recent years, the Road Traffic Act was revised (2000
(Enforced April 1, 2013), it is mandatory to wear a child seat when riding an infant under the age of six. As a result, the number of child seats shipped has increased dramatically.

Conventionally, a child seat is often referred to as a "seat type (also referred to as a bucket type)" today, which is a type in which a child seat is installed on a vehicle seat. Met.
A seat-type child seat generally has a seat portion and a shell (backrest), and has a structure in which a seated infant's body is restrained by a belt or the like to be fixed to the child seat.

However, although such a sheet type child seat is excellent in toughness, it is usually 6 kg to 10 kg.
It weighs around kg and is difficult to carry into vehicles. In addition, since many of them are bulky, it is not always easy to mount them on a seat, and this is a cause of poor mounting of the child seat.

When the child seat is improperly mounted, an infant may be turned upside down or thrown forward in the event of a collision, leading to an unexpected accident. Therefore, it is necessary for the passenger to constantly check the wearing state, but each time he / she has to shake the heavy child seat to confirm. Also, as the baby grows, it is necessary to replace it with a seat that fits the weight, but the child seat is not always cheap.

Under these circumstances, in recent years, a "clothing type" child seat has been developed based on an idea completely different from the seat type. This is a "clothing-type restraint band" that is restrained by wearing a restraint band that resembles so-called vest-shaped infant clothing.
Is a type that is fixed with a seat belt.

Several clothes-type child seats have been proposed so far. For example, Japanese Patent Application Laid-Open No. 2001-294120 discloses a clothing type infant protector for a vehicle, which has a front body and a back body and is opened so that a neck and an arm can pass through.

[0008] An infant is restrained by wearing another vest over the clothes.
Even if various sizes are prepared, it cannot be said that they can be fitted so as to fit the bodies of all infants accurately. Also, since infants sweat more than adults,
When restrained by such a clothing type, there is a possibility that the seat belt is loosened due to being cramped, uncomfortable, unwillingly violent, and the like. Furthermore, it has been pointed out that the vest type may cause abdominal pressure by the waist belt.

By the way, regarding the child seat,
Since January 1, 2000, the Ministry of Land, Infrastructure, Transport and Tourism's safety standards “Standards for Specifying Device Type of Child Auxiliary Riding Device” (hereinafter referred to as new standards) have been revised. According to the new standard, for example,
The amount of movement of the dummy head in an impact test equivalent to a speed of 50 km / h was 550 m when it was 600 mm or less according to the old standard.
It has become a stricter type designation standard, such as being revised to m or less. Therefore, clothing type child seats must also meet these strict type designation standards.

[0010]

SUMMARY OF THE INVENTION The present invention has been made in order to overcome the above-mentioned problems against the background of such circumstances. If the child seat is not a vest type as described above but a harness type child seat in which various harnesses (belt belts) are connected to each other, it is excellent in preventing sweating of infants and easily adaptable to wearability and fit.

An object of the present invention is to provide a harness type child seat that can be freely and accurately mounted on the body of an infant. Another object of the present invention is to provide a harness-type child seat that is strong and can be manufactured at low cost. Furthermore,
It is to provide a harness-type child seat with improved safety.

[0012]

Thus, the present inventor has
As a result of earnest research on such a background,
When the harness-type child seat is fitted properly to fit the infant's body, the impact on the infant in the event of a collision can be further reduced, and the harness-type child seat can be adjusted to the infant's body accurately by providing a side adjustable band. The present invention has been completed based on this finding based on the finding that it can be fitted and that the amount of movement of the head of an infant at the time of a collision can be reduced by inserting a reinforcing plate into the back cloth. .

That is, the present invention is (1) a harness-type child seat including a harness, which includes a chest connecting band and a pair of left and right hung from the back waist through the shoulders to the chest. Shoulder straps, upper back straps and lower back straps that connect the shoulder straps to the left and right on the back, and side straps that connect the shoulder straps on the back and extend left and right to the chest. The harness type child seat includes a leg restraint band formed by extending the lower back communication band to the left and right.

And (2), the side bridging band exists in a harness type child seat which can be separated or connected and whose length can be adjusted.

Further, (3), the leg restraint band exists in a harness type child seat which can be separated or connected and whose length can be adjusted.

Further, (4), the lower back communication band is composed of two harnesses, and the leg restraint band is a harness type child seat formed so as to pass between them.

Further, (5), the harness-type child seat includes a ring body, and a chest connecting band, a shoulder band, a side band, and a leg restraint band are respectively connected to the ring body, It exists in a harness type child seat that is slidably or rotatably connected along a ring body.

Further, (6), the harness-type child seat is a harness-type child seat including a chest pad and a back pad.

Further, (7), the backing cloth is a harness type child seat having a reinforcing plate.

If the present invention meets this objective,
Of course, a configuration in which two or more selected from the above 1 to 7 are combined can also be adopted.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a harness type child seat according to the present invention will be described below with reference to the drawings. The harness type child seat of the present invention,
According to the new standard of the Ministry of Land, Infrastructure, Transport and Tourism, 3-point universal (general purpose)
Belonging to the auxiliary riding system for children.

That is, it is a type in which an auxiliary riding device for children (that is, a child seat) is restrained on a seat by using a three-point type seat belt provided in a front seat of an ordinary vehicle. FIG. 1 is a diagram showing a harness type child seat according to the present embodiment, (a)
Is a front view and (b) is a rear view.

The harness-type child seat A of the present invention has a basic structure in which a shoulder strap 2, a chest connecting strap 3, a side strap 4, and a leg restraint strap 5 are connected to a pair of left and right ring bodies 1 on the chest, On the back, on the back is a contact strip 6, a side strip 4,
Further, the shoulder lower band 2 is connected to the left and right by a lower back connecting band 51 (which forms a part of the leg restraint band 5 as described later). A chest support cloth 7 is provided on the chest surface and a back support cloth 8 is provided on the back surface, and the back support cloth 8 is provided with a reinforcing plate described later.

The ring body 1 is a pair of left and right metal annular bodies provided in front of the chest cloth 7, and has a shoulder band 2, a chest connecting band 3, a side band 4, and a leg restraining band 5, respectively. It is independently connected to the ring body 1 (see FIG. 2). Also,
The shoulder straps 2 and the like have their ends passed through the ring body 1 and folded back and firmly sewn, and can be freely slid or rotated along the ring body 1.

By the way, the ring body 1 is not directly sewn to the breast pad cloth 7, but the shoulder band 2 and the chest connecting band 3 are sewn to the breast cloth 7 at the stitching positions 2a and 3a. , At the position shown in FIG.

A pair of shoulder straps 2 are provided on the left and right sides, and are sewn from the back waist portion to the left and right ends of the back support cloth 8 and hang down to the chest surface via the shoulder portions and connected to the ring body 1. In addition, from the shoulder portion to the chest surface, the breast pad cloth 7 is sewn. The chest contact strip 3 connects the ring body 1 to the left and right on the chest,
As described above, the breast pad cloth 7 is sewn at the central suture position 3a.

The side bridging belt 4 is sewn left and right near the center of the backing cloth 8 to connect the shoulder bridging belt 2, and extends left and right as it is to the chest surface to be connected to the ring body 1. Armpit 4
Can be connected or separated by a connecting fitting (a cover body 4c portion in FIG. 1). 3A and 3B are diagrams showing a procedure for attaching the connecting metal fitting of the side bridging band, where FIG. 3A shows before locking, FIG. 3B shows during locking, and FIG. 3C shows after locking [(b) and In (c), the cover body 4c is partially omitted for convenience sake].

The first connecting fitting 4a and the second connecting fitting 4b are
It is attached by passing each free end of the cut harness (side arm band 4) through each connecting fitting and folding it back. By locking them as shown in the figure, the side strips 4 separated from each other in the front and rear are connected.

Further, by reversing this procedure, the separation can be easily carried out. The cover body 4c is provided with hook-and-loop fasteners and the like, and by covering the periphery of the connecting metal fitting locked in the state of (c) with the cover body 4c, the connecting metal fitting is prevented from coming off, and the connecting metal fitting is further prevented. It is possible to prevent the chest protection pad (7a in FIG. 1) described later from being scratched and scratched.

Further, the armpit 4 is formed so that its length can be adjusted, so that it can be freely and appropriately attached so as to fit the body of an infant. FIG. 4 is a diagram for explaining the length adjustment of the side bridging band (the cover body 4c is omitted for convenience).

As described above, the free end 4d of the armpit 4
Is folded back through the connecting metal fitting 4a, and is pressed by the retaining ring 4e so as to overlap with the side bridging band 4. By pulling this free end 4d to the left side of the figure, the armpit 4
Can be shortened to fit the body of an infant (length adjustment mechanism). The harness type child seat according to the present invention can be properly attached to the body of an infant by the length adjusting mechanism of the armpit.

The leg restraining band 5 is formed by extending left and right lower back connecting bands 51 sewn left and right at the lowermost end of the back support cloth 8 and finally connected to the ring body 1. It Therefore, the lower back communication band 51 forms a part of the leg restraint band 5. Here, for convenience, the part from the backing cloth 8 to the connecting fitting (cover body 5a) described later is also referred to as the lower back connecting strip 51, and the part from the connecting fitting to the ring body 1 is referred to as the leg restraint strip 5.

FIG. 5 shows a front view of FIG. 1 (a).
FIG. 4 is an enlarged view of a portion where the leg restraining band 5 and the lower back communication band 51 intersect (a rear lower communication band 51 is partially deleted and expressed). In this manner, the lower back communication band 51 is composed of two front and rear harnesses in this portion, and the leg restraint band 5 is formed so as to pass between them.

Actually, as shown in the figure, a leg restraint band positioning band 51a is provided in an annular shape between the two harnesses,
The lateral displacement of the leg restraint band 5 is prevented. However, the leg restraint band 5 and the leg restraint band positioning band 51a are not sewn together, and the leg restraint band 5 can freely move in the vertical direction (the arrow direction in the drawing). This allows infants to move their limbs freely, but the important role that these structures play in a collision will be described in detail later.

As shown in FIG. 1 (b), the upper back connecting band 6 is sewn to the upper end of the backing cloth 8 to connect the left and right shoulder bridges 2. Similar to the side bridging band 4, a connecting metal fitting is attached to the lower back communication band 51 at the position of the cover body 5a, and the connecting metal fitting attached to the leg restraining band 5 is engaged or disengaged to connect or It is separable. Further, the same length adjusting mechanism as that described above is also provided, and the leg portion of the infant is properly restrained. At the time of use, the periphery of the connecting fitting is covered with a cover body 5a for use (see FIG. 1).

Here, each of the above-mentioned harnesses, that is, the shoulder straps 2, the chest straps 3, the side straps 4, the leg restraint straps 5, the upper back straps 6, and the lower back straps 51 are made of tensile strength. Since the sheath has an appropriate elongation, it is possible to effectively absorb a shock due to a collision or the like, and therefore, it is preferable to use the polyamide fiber of the twill weave. However, it goes without saying that other materials can also be used as long as they can meet the new standards of the Ministry of Land, Infrastructure, Transport and Tourism.

Next, the chest cloth 7 is for covering and protecting the chest of the infant, and is formed so as to extend from the chest surface toward both shoulders. As mentioned above, the breast cloth 7 is
The shoulder strap 2 is sewn from the shoulder portion to the suture position 2a (see FIG. 2), and the chest connecting strip 3 is sewn at the suture position 3a.

It is preferable that a chest protection pad 7a is provided on the back side of the chest pad cloth 7 because the effect of protecting the chest pad cloth 7 and the infant's chest from an impact at the time of a collision is enhanced. For reference, FIG. 6 shows a state in which the chest pad 7 is viewed from the back side. In this way, the chest protection pad 7 a is sewn to the inside of the chest support cloth 7 with the suture thread N.

A knitted fabric is preferably used as a material for the chest pad cloth and the chest protection pad, and in particular, a double Russell knitted fabric is preferable from the viewpoints of breathability and pulling followability. In the present embodiment, a polyester double made up of a mesh surface having a honeycomb-shaped honeycomb structure, a stretchable plain weave surface, and a connecting layer that ties the fibers between them to provide cushioning to the knitted fabric. Russell knitted fabric is used.

In the double raschel knitted fabric having such a structure, the mesh surface has a moisture absorbing function, and the tent surface has a sweating function. Therefore, the breast pad cloth and the chest protection pad are rich in sweating ability, can follow pulling in any of the surface directions, and have excellent cushioning properties against impact.

Further, since it is made of polyester, it is strong against pulling and is not easily torn, and since it is easy to dry, it has the advantages that it immediately evaporates the sweat of the infant and there is no stickiness.
Thus, the harness-type child seat of the present invention,
The poor sweating characteristic of the conventional best type child seat is eliminated.

Next, as shown in FIG. 1 (b), the backing cloth 8 has an upper back communication band 6 at its upper end, a lower back communication band 51 at its lower end, and shoulder shoulder bands 2 at its left and right ends. Are sewn, respectively, and are also sewn to the side bridging belt 4 in a form crossing the vicinity of the center. Now, this harness type child seat is provided with a reinforcing plate on its back cloth. FIG. 7 shows a state in which the backing cloth is cut vertically and the reinforcing plate and the like are pulled out. In this figure, the front side corresponds to the front side (that is, the rear side of the infant).

The backing cloth 8 is mainly composed of a base cloth 8a, a bag cloth 8b,
It is composed of a cushion body 8c and a reinforcing plate 9. In this embodiment, the base cloth 8a, the bag cloth 8b, and the cushion body 8c adopt the double Russell knitted fabric for the same reason as above.

The base cloth 8a has a mesh surface 8a1 on the front surface and an awning surface 8a2 on the rear surface (a connecting layer 8a3 between the two).
The upper back connecting band 6 on the upper side to the lower connecting band 51 on the lower side are formed by one double Russell knitted fabric. Base cloth 8a
A bag cloth 8b is sewn below the front surface of the base cloth 8a.
The cushion body 8c and the reinforcing plate 9 are sandwiched between the bag cloth 8b and the bag cloth 8b.

The cushion body 8c serves as a cushion for protecting the back of the infant from the reinforcing plate 9. In the present embodiment, the double Russell knitted fabric, which is rich in cushioning properties as described above, is folded in two. It is sandwiched between. Further, the reinforcing plate 9 preferably has both rigidity and elastic deformability as described later, and a vinyl chloride plate is used here. Since the harness-type child seat of the present invention has the above-described structure and materials, it is lightweight, strong, and inexpensive to manufacture.

Next, a method of mounting the harness type child seat of the present invention will be described. The harness-type child seat of the present invention is worn on an infant, and then the infant is seated on the seat of the vehicle and fixed to the seat belt. First,
Assume that a child wears a harness-type child seat.

First, the chest pad 7 and the back pad 8 and the two shoulder straps 2 are spread out to cover the infant from the head. Then, the side bridging belts 4 separated from each other are connected to each other and the free end is pulled to fit the harness type child seat to the upper body of the infant. The connecting metal fittings connecting the armpits 4 are covered with a cover body 4c.

After that, if the connecting member of the leg restraint band 5 is connected, remove it and pass it under the crotch to surround the infant's leg.
Lock the connection fittings to connect them. Then, as in the case of the armband, the free end is pulled to fix the infant's leg without being strongly tightened, and the connecting fitting is covered with the cover body 5a. In this way, wearing of the harness type child seat is completed (see FIG. 8).

Next, the harness type child seat is attached to the seat with the seat belt. As described above, this harness-type child seat is of a type that is restrained (mounted) on the seat by using a three-point seat belt.

For reference, FIG. 9 is a view of the state in which the harness type child seat is mounted by the seat belt, as viewed from the rear (back side). First, the infant is seated on the seat, and in that state, the seat belt 10 is inserted between the back of the infant and the backrest cloth 8 of the harness type child seat. In this case, the seat belt 10 passes between the shoulder bridging band 2 and the side bridging band 4 on one side (the left side in the drawing) and goes out under the side bridging band 4 on the other side (the right side in the drawing). Then, the tongue 11 is inserted into the buckle 12.

At this time, if the seat belt is loose, the harness type child seat cannot perform its function. Therefore, the length of the seat belt 10 is adjusted so that the so-called shoulder belt 10a and the waist belt 10b are stretched. adjust. However, if you pull the waist belt 10b too strongly,
Since the posture of the infant leans (lower left in FIG. 9), the waist belt 10b is tensioned to the extent that the normal posture can be maintained.

Finally, the positioning belt 13 is attached to the shoulder belt 10a.
Wrap and stop. The positioning band 13 is for preventing the position of the seat belt from being displaced even when the infant moves the body, and is wound around the seat belt and can be stopped by, for example, a hook-and-loop fastener. In this way, the wearing of the harness type child seat by the seat belt is completed.

Next, the characteristics of the harness type child seat of the present invention at the time of collision will be described. When a harness-type or vest-type child seat is attached, the movement of the dummy (model assuming an infant) in the impact test at the speed of 50 km / h described above is generally ideal as follows. It is said that there is.

FIG. 10 schematically shows the movement of the dummy in the collision test. First, when a vehicle collides, the entire body of the dummy 15 seated on the seat 14 starts to move forward due to inertia (a). Next, when the waist of the dummy 15 comes out to some extent forward, it stops, and at the same time, the upper body leans slightly forward (b). Then, both the upper body and the lower back are pulled back to return to a state close to the initial sitting posture (c).

Here, if the forward movement of the waist does not stop in the above (b), the dummy falls down on its back as it is (so-called submarine phenomenon), and at the next moment, it is pulled back by the rebound and from the head to the backrest 14a of the seat 14. It is struck (see FIG. 11). If this happens, the neck and head will be seriously damaged.

On the other hand, on the other hand, if the waist of the dummy 15 is strongly fixed so that it does not project to the front at all, only the upper body of the dummy 15 tilts forward due to a collision (so-called jack knife phenomenon). , Instantly receive strong force on the chest from the seat belt. As a result, the dummy suffers a strong impact on the chest and neck, and also suffers great damage.

That is, rather than a momentary strong force being applied to the dummy as in the above example, a smaller force is taken over a relatively long time until the dummy body starts moving and the upper body leans forward and stops. It is good to stop the dummy from moving forward. that way,
The “composite acceleration of the chest”, which is a measure of the impact of the dummy on the chest according to the type designation standard of the Ministry of Land, Infrastructure, Transport and Tourism, can be made smaller. Moreover, at that time, instead of applying force only to the upper body of the dummy, that is, the chest, to stop the movement by distributing the force to the waist and the chest, it is possible to further reduce the force applied to the chest. (Fig. 10
reference).

The harness type child seat of the present invention is
It is possible to realize movements that are as similar as possible to such ideal movements during a collision. According to the present invention, the relatively high position of the harness type child seat A is fixed by the seat belt 10 (see FIG. 9), and the waist portion is not strongly fixed. Therefore, at the time of a collision, the entire body including the waist begins to move forward [see FIG. 10 (a)].

When the infant's body moves forward, the seat belt 1
0 pulls the back support cloth 8 backward. That power is shoulder belt 2,
It is transmitted to the armpit 4 and the lower back communication belt 51, and a backward force is applied to the chest and waist of the infant. At this time, if these harnesses have an appropriate degree of elongation with respect to pulling as described above, it becomes possible for the harnesses to absorb force and to be relaxed in addition of force. .

The force transmitted to the lower back communication band 51 is transmitted to the leg restraint band 5 on the extension thereof, and the leg restraint band 5 pulls the infant's waist and chest (via the ring body) backward. Here, the leg restraint band 5 intersects with the lower back communication band 51 and the like as described above, but is not sewn (see FIG. 5). Therefore, the leg restraint band 5 is appropriately moved vertically between the lower back communication band 51 and the like while pulling the infant's waist and chest backward.
It naturally fits in the most precise position (autonomous adjustment function of the leg restraint band).

Thus, the forward movement of the waist is stopped mainly by the leg restraint band, and at the same time, the upper body begins to lean forward (see FIG. 10 (b)). However, as described above, by this point of time, the body of the infant has already been applied with a pulling force through the shoulder strap 2 and the like, and the deceleration has started.

Also, the properties of the harness, the chest cloth, etc., which are appropriately extended, are exhibited here, and the upper body of the infant is gently tilted forward and stopped without giving an excessive impact to the chest of the infant. As described above, according to the present invention, the synthetic acceleration applied to the chest of an infant can be practically suppressed to be small enough to meet the new standard of the Ministry of Land, Infrastructure, Transport and Tourism, and furthermore, the collision as described above. It is possible to achieve the ideal movement over time.

Now, various functions exerted by the harness type child seat of the present invention at the time of collision will be described.

The autonomous adjustment function of the leg restraint band has already been described. Similarly, since the harnesses such as the shoulder strap 2 and the side straps 4 connected to the ring body 1 also have the freedom of movement, it is possible to cope with the ever-changing posture of the infant. That is, by sliding or rotating along the ring body 1 (see FIG. 2), the infant's chest is accurately caught in an optimal position, and the rearward pulling force is effectively transmitted to the entire body. . That is, the harness-type child seat of the present invention is formed so that each harness has a function of autonomously adjusting its position.

Further, the present invention is also characterized in that the side band 4 is provided. As described above, the harness type child seat can be accurately fitted to the infant's body by providing the armpit with the length adjustment mechanism (fitting function by the armband).

In such a state, the shoulder band, the side band, and the like can accurately transmit the force to the chest cloth, and the above ideal movement can be realized. Therefore, in the harness type child seat, it is necessary to fit the body of the infant, and in the present invention, the fitting function by the side bridging band having the length adjusting mechanism particularly plays this important role.

On the other hand, since the side bridging band is provided, at the time of a collision, not only the vertical pulling by the shoulder bridging band or the leg restraining band but also the lateral pulling is applied to the chest cloth. Therefore, the force applied to the breast pad cloth is dispersed, and the entire breast pad cloth can evenly apply the force to the chest of the infant. Therefore, it is possible to wrap the entire chest and apply a force to stop the movement of the infant without applying strong biased pressure to the chest (wrapping function).

Another feature of the present invention is that the backing cloth is provided with a reinforcing plate. 12 and 13 are views showing a state at the time of collision, FIG. 12 shows a case where a harness type child seat having a reinforcing plate is worn, and FIG. 13 shows a case where the reinforcing plate is not provided.

As shown in FIG. 13, a reinforcing plate (see FIG. 7)
In the case of a general harness-type child seat B that does not include the child seat B, when the body of the infant moves forward, the child seat B bends and is intensively supported by the seat belt 10 at one point. Therefore, the upper body of the infant leans forward greatly, and causes great damage to the chest and neck.

On the other hand, in the case of the harness type child seat A of the present invention shown in FIG. 12, since the backing cloth 8 is provided with the reinforcing plate, the portion of the reinforcing plate and the seat belt 10 are supported within a certain length range, and one point is concentrated. Does not happen. Therefore, the amount of movement of the head of the infant is reduced accordingly, and the burden on the neck and the like can be reduced (head movement amount suppressing function). Due to such a function, the new standard of the Ministry of Land, Infrastructure, Transport and Tourism for the amount of movement of the dummy head described in the prior art can be sufficiently satisfied.

In order for the reinforcing plate to exert such a function, it is preferable that the material of the reinforcing plate has rigidity, but it is preferable that it is not brittle. That is, as described above, it is preferable that the reinforcing plate is a material that appropriately has not only rigidity but also elastic deformability. In this embodiment, the vinyl chloride plate is used as described above, but a metal plate, a carbon graphite plate, or the like can naturally be adopted.

The present invention is a harness-type child seat that is more safe as a whole by exhibiting the above-mentioned functions.

Finally, for reference, the seat belt will be briefly described. The three-point seat belts currently installed in most vehicles are emergency lock retractors (E
It is a three-point seat belt of the LR type. This is a type of seat belt that does not lock when pulled slowly, but locks when pulled with force.

However, in reality, it is 7c from the winding device.
There are many things that are locked only after being pulled out about m.
If it is used as it is, the effect of the head movement amount suppressing function of the reinforcing plate may be halved. Therefore, in such a case, pull out the seat belt as much as possible,
A method in which the lock is applied from the beginning is preferable. Since the seat belt is shortened by using a length adjusting tool or the like with the seat pulled out to the maximum extent, and the seat belt is mounted and fixed in the state shown in FIG. 9, the function of the present invention can be more effectively exhibited. is there.

Although the present invention has been described above, it is needless to say that the present invention is not limited to the embodiments and various other examples can be made without departing from the essence thereof. For example, it is of course possible to attach a connecting fitting to the chest connecting band so that it can be opened and closed in front of the chest.

In FIG. 7, the reinforcing plate is inserted at the lower side of the backing cloth, but it is naturally possible to insert it at the upper side or the entire surface of the backing cloth. Further, it goes without saying that the way of passing the seat belt shown in FIG. 9 can be changed as long as the above-mentioned function is exhibited.

[0077]

According to the present invention, by using a harness type child seat having a harness connected thereto and having a material having excellent sweating property, it is possible to easily cope with sweating of an infant. In addition, it can be attached to the infant's body freely and accurately,
Therefore, the safety is further increased.

Further, unlike the conventional seat type child seat, it is not bulky at the time of mounting and storing, is convenient to carry, and is durable and can be manufactured at low cost.
Further, by having the ring body, each harness is placed in an optimum position and autonomous adjustment is performed.
