The upper engaged guide member 44 is rotatable while being covered by the covering member 45. In the covering member 45, a through hole 45a is formed at a corresponding position so that the respective distal ends of the upper connecting rod 43 can pass through the covering member 45 to be engaged with the guide wall 44a of the upper engaging guide member 44. Further, the upper connecting rod 43 is not exposed to the outside, and the protective cover 46 is covered from the upper side with respect to the upper connecting rod 43. The protective cover 46 is attached to the cover member 45. In addition, in FIG. 10, the cover member 45 and the protective cover 46 are abbreviate|omitted.

The covering member 45 is made by using acrylonitrile. Butadiene. Although styrene or the like is integrally molded, it is not limited thereto. Further, the protective cover 46 is formed by integrally molding a hard plastic such as polypropylene, but is not limited thereto. The lower connecting rod 41 and the upper connecting rod 43 are formed of a metal such as carbon steel, but are not limited thereto.

The internal mechanism of the tilting mechanism and the rotating mechanism will be described in detail with reference to FIGS. 6, 9, 10, and 11. FIG. 11 is an enlarged perspective view of the inside of the seat body 30 of the child seat 1. The upper portion of the seat lower portion 31 of the seat body 30 is covered by a seat panel 34 that forms a seat on which the infant rides. The cover, and the seat panel 34 constitutes an internal space 35 below it.

A lower portion corresponding to the circular opening 33a at the center of the seat bottom surface 33 of the seat body 30 is engaged with the center of the guide member 40, and a circular opening 40b of the same diameter is formed (FIG. 6). For the circular opening 33a of the seat bottom surface 33 and the circular opening 40b of the lower engagement guide member 40, a cylindrical drop lock pin 50 is inserted from the inner space 35 side of the seat body 30. The front end of the drop lock pin 50 projecting downward from the lower surface of the lower engagement guide member 40 is inserted into any one of the lock holes 25a formed in the lock hole 25a of the cylindrical curved surface 25 of the receiving table 20. And the engagement is made.

Further, a line which is offset from the center of the circular opening 40b of the engagement guide member 40 to the left side from the two circular openings 33b of the seat bottom surface 33 of the seat body 30 is formed with 2 A circular opening 40c (Fig. 6). The U-shaped rotary locking pin 51 is inserted from the side of the internal space 35 of the seat body 30 with respect to the two circular openings 33b of the seat bottom surface 33 and the two circular openings 40c of the lower engagement guide member 40. Each front end. The respective distal ends of the rotary lock pins 51 projecting downward from the lower surface of the lower engagement guide member 40 are inserted into one of the lock grooves 25b formed in the cylindrical curved surface 25 of the receiving table 20 to be engaged.

Therefore, the offset from the center of the circular opening 33a of the seat bottom surface 33 to the aligned line of the two circular openings 33b, and the center of the circular opening 40b from the lower portion of the engaging guide member 40 to 2 circles The offset amount of the aligned lines of the shaped openings 40c is set to be equal to the offset amount from the locking groove 25b formed in the cylindrical curved surface 25 of the receiving table 20 to the center line H.

With particular reference to Figure 11, within the seat bottom surface 33 of the seat body 30 On the side surface, that is, on the bottom surface of the internal space 35, a first guiding projection 33c and a second guiding projection 33d which protrude upward and have a rectangular cross section are formed. The first guiding projection 33c is disposed on the right side, and the second guiding projection 33d is disposed on the left side. The first guide projection 33c and the second guide projection 33d have a tip end that is slightly tapered toward the upper side.

In the first guide projection 33c, the first pin holding member 52 is slidably attached to the vertical direction, and in the second guide projection 33d, the second pin holding member 53 is slidably attached in the vertical direction. In other words, the first pin holding member 52 is formed with a complementary rectangular opening in which the first guiding protrusion 33c can be accommodated, and the second pin holding member 53 is formed to be complementary to the second guiding protrusion 33d. Rectangular opening. The first pin holding member 52 holds the above-described tilt lock pin 50, and the second pin holding member 53 holds the above-described rotary lock pin 51. The first pin holding member 52 is biased downward by the coil spring 54a, and the second pin holding member 53 is biased downward by the coil spring 54b.

An operating mechanism is mounted on a front portion of the seat body 30 above the seat lower portion 31. The operating mechanism has a console 55. On the right side of the console 55, a tilting operation lever 55a that can operate the tilting mechanism is slidably attached to the front-rear direction as the first operating portion. Further, on the left side of the console 55, a rotation operation lever 55b that can operate the rotation mechanism is slidably attached to the front-rear direction as the second operation portion. The first pin holding member 52 is connected to the tilt operation lever 55a via an operation lever 56a that extends obliquely upward. Further, the second pin holding member 53 is connected to the rotational operation lever 55b by the operation lever 56b extending obliquely upward.

When the tilting operation lever 55a is pulled forward, the operating lever is transmitted through In the 56a, the first pin holding member 52 slides upward along the first guiding projection 33c. Thereby, the tilt lock pin 50 held by the first pin holding member 52 also moves upward, and the engagement between the front end of the lock lock pin 50 and the lock hole 25a is released. As a result, the seat body 30 is in a state in which the tilting operation can be performed.

The tilting operation lever 55a is biased by the operation force of the coil spring 54a that gives the potential energy to the lower side of the first pin holding member 52, and is given a potential energy to the rear position through the operation lever 56a. Therefore, after the tilting operation, when the reverse operation lever 55a is opened, the force of the potential of the coil spring 54a is applied, and the operation lever 55a is returned to the rear position, and the front end of the lock pin 50 is reinserted. Locking hole 25a.

On the other hand, when the rotational operation lever 55b is pulled forward and transmitted through the operation lever 56b, the second pin holding member 53 slides upward along the second guide projection 33d. Thereby, the rotation lock pin 51 held by the second pin holding member 53 also moves upward, and the engagement between the respective tips of the rotation lock pin 51 and the lock groove 25b is released. As a result, the seat body 30 is in a state in which the rotation operation is possible.

The rotational operation lever 55b is biased by the operation force of the coil spring 54b that gives the potential energy to the second pin holding member 53 downward, and is given a potential energy to the rear position through the operation lever 56b. Therefore, after the rotation operation, when the rotation operation lever 55b is released, the rotation operation lever 55b returns to the rear position by the force of the potential of the coil spring 54b, and the front ends of the rotation lock pins 51 are also inserted into the lock. Inside the groove 25b.

The tilting mechanism and the rotating mechanism of the child seat 1 will be described with reference to Figs. 12 and 13 . Figure 12 is a view showing the tilting mechanism and the rotation of the child seat 1 FIG. 13 is a view for explaining the tilting mechanism and the rotating mechanism of the child seat 1. In Fig. 12 and Fig. 13, each configuration is schematically shown.

As described above, the seat body 30 has the lower engaged guide member 40, the upper engaged guide member 44, and the cover member 45. Further, the lower connecting rod 41 and the upper connecting rod 43 connected by the rod connecting member 42 are engaged with each other while being engaged with each other between the lower engaged guide member 40 and the upper engaged guide member 44. The lower connecting rods 41 are guided by the pair of upper connecting rods 43 respectively passing through the corresponding guiding grooves 22b of the receiving table 20, and the rod connecting members 42 abutting against the inner side surfaces of the inclined surfaces 22a of the receiving table 20, and The upper connecting rod 43 slides in the front-rear direction and restricts the movement in the lateral direction.

In Fig. 12, the seat body 30 is a retracted position corresponding to the rear locking hole 25a among the three locking holes 25a. In other words, the seat body 30 is engaged with the locking pin 50a that protrudes downward from the seat body 30 through the lower engagement guide member 40, thereby fixing the retracting position. .

Further, the outer surface of the seat lower portion 31 of the seat body 30 is supported by the receiving platform support surface 24 of the receiving base 20 so as to be able to withstand the load of the infant when riding. The cylindrical curved surface 25 of the lower engagement guide member 40 and the receiving table 20 is arranged to be slightly separated only a little. The outer surface of the seat lower portion 31 is slid and supported on the receiving table support surface 24 of the receiving base 20 during the tilting operation and the rotating operation of the seat body 30. Further, the lower engaged guide member 40 is slightly separated from the cylindrical curved surface 25 of the receiving base 20 by a little bit during the tilting operation and the rotating operation of the seat body 30. In other words, seat The size, shape, and the like of the outer surface of the chair body 30 are determined such that they can always abut against and support the receiving table support surface 24; and the size or shape of the lower portion of the engaging guide member 40 is determined. It is: it will be slightly separated from the cylinder surface 25 a little.

The seat body 30 abuts in a point shape with the convex curved protrusion 24a formed on the receiving table support surface 24 of the receiving base 20, whereby the frictional resistance can be reduced and the sliding can be smoothly performed.

In this state, by releasing the engagement between the rotary lock pin 51 (not shown) and the lock groove 25b, the seat body 30 can be rotated about the axis of rotation substantially coincident with the center axis of the drop lock pin 50. R rotates. Further, the tilt lock pin 50 and the rotary lock pin 51 are formed of a metal such as carbon steel, but are not limited thereto.

When the seat body 30 is rotated with respect to the receiving table 20, the lower portion of the seat body 30 is engaged with the guiding member 40, and the engaging hook 41a of the lower connecting rod 41 and the annular engaging groove 40a are provided. In the engaged state, it rotates together with the seat body 30. At this time, since the movement of the lower connecting rod 41 in the lateral direction as described above is restricted, it is relatively stationary with respect to the receiving base 20. Therefore, the engagement hooks 41a of the lower link rod 41 are engaged with each other while being engaged with the ring-shaped engagement groove 40a of the lower portion of the engagement guide member 40.

Further, when the seat body 30 is rotated with respect to the receiving base 20, the guide member 44 is engaged with the upper portion of the seat body 30, and the front end of the upper connecting rod 43 and the cylindrical guide wall are provided. The 44a is rotated together with the seat body 30 in a state of being engaged. At this time, the upper connecting rod 43 is opposite to The docking station 20 is relatively stationary. Therefore, the respective distal ends of the upper connecting rods 43 are always engaged with each other along the cylindrical guide wall 44a of the upper portion of the engaging guide member 44, and are relatively slid.

The cover member 45 covering the upper portion of the engaging guide member 44 and the protective cover 46 of the upper connecting rod 43 are relatively stationary with respect to the receiving table 20 together with the upper connecting rod 43. That is, the covering member 45 maintains the state of covering the upper engaged guide member 44 when the upper portion of the engaging guide member 44 is rotated as the seat body 30 rotates, and the covering member 45 itself does not rotate. .

Fig. 13 shows a state in which the seat body 30 is tilted from the lowered position shown in the rear side shown in Fig. 12 to the front down position with respect to the receiving base 20. That is, from the state shown in Fig. 12, the engagement between the drop lock pin 50 and the rear lock hole 25a is released, and the seat body 30 is slid forward along the receiving table support surface 24. Next, the knock-out locking pin 50 is engaged with the front locking hole 25a, thereby fixing the falling position.

The lower connecting rod 41 and the upper connecting rod 43 between the lower engaging portion of the seat body 30 and the upper engaged guiding member 44 follow the tilting action of the seat body 30, and along The guide groove 22b of the receiving table 20 slides in the front-rear direction. Therefore, the seat body 30 performs the tilting operation and the rotating operation on the receiving base 20, but the lower connecting rod 41 and the upper connecting rod 43 connected by the rod connecting member 42 are stuck to the lower portion of the seat body 30. The engagement guide member 40 and the upper engagement guide member 44 are always engaged, that is, while being maintained in a relative positional relationship with the seat body 30.

In addition, it is of course also possible to make the seat body 30 a lock with the center. The fixing hole 25a corresponds to the falling position. When the seat body 30 is in the retracted position corresponding to the central locking hole 25a and the retracted position corresponding to the front locking hole 25a, the seat body 30 can also be rotated around the locking pin. The central axis of 50, that is to say the rotational movement about the axis of rotation R.

The tilting operation and the rotating motion of the child seat 1 will be described with reference to Figs. 14 and 15 . Fig. 14 is a view for explaining the tilting operation of the child seat 1, and Figs. 14(a) to (d) show the tilting operation in time series. 15 is a view for explaining the rotation operation of the child seat 1, and FIGS. 15(a) to (d) show the rotation operation in time series.

In each of Figs. 14 and 15, three locking holes 25a, two locking grooves 25b, a drop lock pin 50, a rotary lock pin 51, a tilting operation lever 55a, and a rotation are schematically shown. The lever 55b is operated. Further, the cylindrical curved surface 25 which is a concave curved surface is schematically shown as a horizontal plane. In each of Figs. 14 and 15, the left side is the front side of the child seat 1, and the right side is the rear side of the child seat 1. Further, in each of Figs. 14 and 15, the upper diagram is a cross-sectional view in the line XX of the following figure, and the viewpoint from the top is schematically shown, and the lower diagram is the line including the above diagram. YY, that is, a cross-sectional view of the line along the lock groove 25b on the left side, schematically shows the viewpoint from the side.

The reversing action is illustrated. Fig. 14(a) shows the forward state of the seat body 30, and is in a state in which the operation lever 55a and the rotation operation lever 55b are not operated. The lock lock pin 50 is engaged with the lock hole 25a at the center of the three lock holes 25a, and the rotary lock pin 51 is engaged with the lock groove 25b on the left side. Fig. 14 (b) is a state in which the tilting operation lever 55a is pulled to the front, and it is displayed: The reverse lock pin 50 is moved upward, and the state of engagement with the lock hole 25a is released.

Fig. 14 (c) shows a state in which the tilting operation lever 55a is pulled to the front and the seat body 30 is slid forward. That is, this action is a tilting operation in which the seat body 30 is tilted down against the receiving table 20. Between the reversing action, the rotary locking pin 51 will engage with the locking groove 25b. Fig. 14 (d) is an operation of fixing the seat body 30 to the receiving base 20 after the seat body 30 has been slid forward, that is, after being tilted. That is, the retracting operation lever 55a is released, whereby the retracting operation lever 55a returns to the rear position, and the retracting locking pin 50 is inserted into the front locking hole 25a to be engaged.

The rotation operation will be described. Fig. 15 (a) shows the forward state of the seat body 30, and is in a state in which the operation lever 55a and the rotation operation lever 55b are not operated. The lock lock pin 50 is engaged with the lock hole 25a at the center of the three lock holes 25a aligned in the front-rear direction, and the rotary lock pin 51 is engaged with the lock groove 25b on the left side. Fig. 15 (b) shows a state in which the rotary operation lever 55b has been pulled forward, and the rotation lock pin 51 is moved upward, and the engagement with the lock groove 25b is released.

Fig. 15 (c) shows a state in which the tilting operation lever 55a has been pulled to the front, and the seat body 30 is rotated by 180 degrees about the rotation axis R of the tilting lock pin 50. That is, this operation is a rotation operation in which the seat body 30 is rotated with respect to the receiving base 20 to change the seat body 30 from the forward state to the rearward state. Between the rotating motions, the locking lock pin 50 is engaged with the locking hole 25a. Figure 15 (d) shows the seat body 30 after the seat body 30 has been rotated. The fixed action of the receiving table 20. That is, the rotational operation lever 55b is released, whereby the rotational operation lever 55b is returned to the rear position, and the rotary lock pin 51 is inserted into the other lock groove 25b to be engaged.

The tilting mechanism and the rotating mechanism of the child seat 1 are as follows: the child seat 1 is provided with a receiving base 20 having a lower connecting rod 41 and an upper connecting rod 43 as an engaging portion, and a lower engaged guiding member 40 and the upper portion of the seat body 30 that is engaged with the engaging portion 44 as the engaged portion of the engaging portion 44 is maintained when the position of the seat body 30 is reversed and the seat body 30 is rotated. Engagement between the engaging portion and the engaged portion. That is, the relative positional relationship of these members is constant. Therefore, the child seat 1 can be used in a simple mechanism in which the number of parts is small and the parts are miniaturized, regardless of the rotational position of the seat body 30 with respect to the receiving table 20, compared to the conventional child seat having the tilting mechanism and the rotating mechanism. The seat body can be lowered.

Further, in the child seat 1, since the tilting mechanism and the rotating mechanism are disposed at the lower portion, that is, disposed at the lower portion of the seat lower portion 31 and the rising portion 22 of the receiving base 20, the seat body 30 is lowered. During the operation and the rotation operation, the seat body 30 is stably supported with respect to the receiving base 20, and as a result, the operation can be performed stably. Further, since the tilting mechanism and the rotating mechanism are disposed at the lower portion of the rising portion 22 of the receiving base 20, the upper portion of the rising portion 22 of the receiving base 20 can be freely utilized.

In addition, since the tilting mechanism and the rotating mechanism are not exposed to the outside during the tilting operation and the rotating operation of the seat body 30, the fingers are not caught, and the safety is excellent, and the design is also excellent.

Moreover, due to the tilting lock pin 50 of the child seat 1 and the rotation lock The pin 51 is formed separately and can be operated independently. Compared with the child seat described in, for example, Patent Document 1, the folding operation and the rotation operation are selected in accordance with the amount of protrusion of the single locking pin. The mechanism to carry out a sure and stable operation. Further, since the amount of protrusion is not required to be changed in accordance with the required operation, the machining accuracy or assembly accuracy of each of the parts of the tilting mechanism and the rotating mechanism is less strict than that of the child seat described in Patent Document 1, and as a result, Can reduce part or manufacturing costs.

Further, the engagement portion and the engaged portion can be arbitrarily configured as long as the engagement between the receiving table 20 and the seat body 30 can be maintained between the tilting operation and the rotating operation. For example, the receiving platform 20 may have only one of the lower engaged guiding member 40 and the upper engaged guiding member 44, and the seat body 30 has a corresponding lower connecting rod 41 and an upper connecting rod. One of 43. The lower engaged guide member 40 may not be in the shape of a disk, but may have a ring shape or a polygonal shape. The lower engaged guide member 40 and the upper engaged guide member 44 may be integrally formed with the seat body 30.

The lower connecting rod 41, the rod connecting member 42, and the upper connecting rod 43 may be integrally formed as a connecting member between the lower engaged guide member 40 and the upper engaged guide member 44. Further, the lower connecting rod 41, the rod connecting member 42, and the upper connecting rod 43 are located rearward of the seat body 30 in the child seat 1, that is, on the rising portion 22 side of the receiving base 20, and are engaged with the lower portion. The guide member 40 and the upper portion are engaged by the engagement guide member 44. However, other components may be provided as long as they can move back and forth in response to the tilting operation of the seat body 30.

In the cylindrical curved surface 25 of the receiving table 20, three locking holes are formed. 25a, but it can also be 2 or more. That is, the tilting position corresponding to the number of the locking holes 25a may be set to an arbitrary number, and the same may not be equal intervals. Further, in the cylindrical curved surface 25 of the receiving table 20, a pair of locking grooves 25b are formed in parallel with respect to the center line H. However, an arbitrary angle, for example, an orthogonal locking groove may be formed for the center line H. That is, in addition to the forward state and the rearward state of the seat body 30, the infant may be faced in a lateral direction and facing the side. In the side facing side, it is also possible to make the reversing action possible by providing a plurality of locking holes in the lateral direction.

Further, as described above, the child seat 1 can cause the seat body 30 to be laid down by pulling the retracting operation lever 55a, and the seat body 30 can be rotated by pulling the rotational operation lever 55b. If these tilting and rotating actions can be performed simultaneously, the seat body 30 can create a complicated and unpredictable trajectory that may hit the operator. Therefore, the child seat 1 is configured such that the tilting operation and the rotating operation cannot be performed at the same time.

An operation mechanism for tilting the operation lever 55a and rotating the operation lever 55b will be described with reference to Figs. 16 to 18 . 16 is a view for explaining an operation mechanism of the child seat 1, FIG. 17 is a view for explaining an operation mechanism of the child seat 1, and FIG. 18 is another view for explaining an operation mechanism of the child seat 1. In FIGS. 16 to 18, the upper side is the rear of the seat body 30, and the lower side is the front of the seat body 30.

The operation switch 57 is a thick plate-like member formed into a shape having a curved side surface such as a crescent shape or a return rod shape. The operation switch 57 is rotatably attached to the console 55 around the fixing pin 57a by a fixing pin 57a in a central portion thereof. On the outside of the curved portion of the operation switch 57, that is, The side surface on the rear side is formed with an abutting surface 57b that is developed outward toward the front of the seat body 30. Further, since the operation switch 57 is covered by the tilt operation lever 55a and the rotation operation lever 55b from above, it cannot be recognized from the outside.

The operation lever 56a is coupled to the tilt operation lever 55a by the lever holding member 58a, and the operation lever 56b is coupled to the rotation operation lever 55b by the lever holding member 58b. That is, the end portion of the operating lever 56a is bent upward, that is, in the drawing, the sheet is vertically bent toward the reader, and the L-shaped rod holding member 58a is formed to be fitted from above. That is, in the drawing, the paper surface is vertically fitted from the direction of the reader, thereby connecting. The same applies to the rod holding member 58b. Further, the lever holding member 58a and the lever holding member 58b may be integrally formed with the tilt operation lever 55a and the rotation operation lever 55b, respectively.

Next, the operation of the operation switch 57 will be described. From the state of the operating mechanism shown in Fig. 16, when the tilting operation lever 55a is pulled forward, that is, pulled downward in the drawing, the lever holding member 58a moves forward together with the operating lever 56a. At this time, the front end of the rod holding member 58a, that is, the front end portion, first comes into contact with the abutting surface 57b of the operation switch 57, and the operation switch 57 is rotated around the fixing pin 57a. When the tilting operation lever 55a is further pulled, as shown in Fig. 17, the tilting operation lever 55a comes into contact with the stopper portion 55c of the console 55 to stop.

In this state, the abutting surface 57b of the rotated operation switch 57 abuts against the side surface of the rod holding member 58a, and the front end of the other rod holding member 58b, that is, the front end portion, and the operation switch 57 The other abutting surface 57b abuts. Therefore, the movement of the rotational operation lever 55b is abutted by the distal end of the lever holding member 58b and the abutment surface 57b of the operation switch 57. Things are blocked. In other words, the shape of the crescent-shaped or the return-force bar that determines the operation switch 57 is such that the abutment surface 57b of the operated operation switch 57 is in contact with the side surface of the rod holding member 58a, and the other rod is held. The front end portion of the member 58b abuts against the other abutting surface 57b of the operation switch 57.

In the state in which the tilting operation lever 55a has been pulled (Fig. 17), the rotational operation lever 55b cannot be pulled, and conversely, in the state in which the rotational operation lever 55b has been pulled (Fig. 18), the fall operation lever 55a cannot be pulled. When one of the tilting operation lever 55a or the rotational operation lever 55b that is pulled to the front is returned to the original position, the tilting operation lever 55a or the rotational operation lever 55b can be pulled forward. Therefore, according to such an operating mechanism, it is possible to prevent the tilting mechanism and the rotating mechanism from simultaneously operating with a simple mechanism, and it is possible to safely implement the alternative operation.

Moreover, since the operation of the child seat 1 for tilting and rotating the seat body 30 can be performed only by pulling the tilting operation lever 55a or the rotary operation lever 55b, it is also possible to operate with only one hand. Free to use the other hand. Moreover, even if the operating mechanism is operated with one hand, the operation can be performed stably.

Further, it is also possible to make it possible to pull one of the tilting operation lever 55a or the rotational operation lever 55b without sliding the lever holding member 58a to the operation switch 57 to abut the side of the lever holding member 58a. It is also possible to restrict the sliding of the other of the tilting operation lever 55a or the rotational operation lever 55b at the timing when the front end of the lever holding member 58a has rotated the operation switch 57. That is, the operation switch 57 may be a rectangular member or the like. In addition, the operating mechanism having the above-described operation switch 57 can be applied not only to children The field of seats can also be applied to other areas where there is a need to safely implement alternative operations.

In particular, referring to Fig. 3, as described above, a rectangular opening 26 is formed in the upper portion of the rising portion 22 of the receiving table 20. In other words, in the child seat 1, the lowering portion 31 and the lower portion of the rising portion 22 of the receiving base 20 can be disposed on the upper portion of the rising portion 22 of the receiving base 20 by the tilting mechanism and the rotating mechanism. An opening 26 is formed. The opening 26 can be utilized as a handle when the child seat 1 is carried.

Further, as shown in FIG. 4, the opening 26 can be equipped with a mechanism or device 90 having various functions. Thereby, the receiving table 20 can have functions other than the supporting function of the seat body 30. In particular, in a state in which the seat body 30 faces rearward, for example, a camera or a camera can be mounted to capture a still image or a dynamic screen, and the parent or the like can observe the appearance of the infant in the ride through a mobile phone or a car navigation system. In addition, a screen can be installed to allow infants and young children to enjoy images. In addition, speakers can be equipped to allow the baby to enjoy the sound. Further, an electric fan, an air conditioner, a lighting device, or the like may be mounted. Further, an ion generating device that discharges ions into the air by plasma discharge or the like may be mounted. According to such an ion generating apparatus, air cleaning effects such as disinfection, dust removal, sterilization, decomposition of organic substances, and deodorization of air, or effects of hair care and skin care for infants or parents' hair or skin care can be expected. . Further, in order to allow these devices and the like to be easily replaced, these devices or the like may be mounted through the mounting member.

In order to use the electric appliance mounted on the opening 26, the battery may be disposed inside the receiving base 20 with a replaceable battery, or the vehicle may be utilized. The cigarette lighter socket is used as a power source. The power cord from the power source such as the battery or the cigarette lighter socket to the electric appliance should be wired so as not to interfere with the lowering and the back of the child seat 1 by the tilting action and the rotating action of the seat body 30, or the wiring is passed through the receiving platform. The interior of 20.

Further, of course, the opening 26 may have a shape other than a rectangle, such as a circular shape. Further, the opening 26 may penetrate rearward or may be only a recess. In addition, the opening 26 as described above can be applied not only to the child seat in which the seat body is tilted and rotated, but also to the type in which the seat body is fixed to the receiving platform, or The seat body is mounted in a form that can be attached and detached to the docking station.

However, the child seat is required to pursue high impact resistance from the viewpoint of protecting the infant under the impact of the vehicle upon impact. The impact resistance can be detected by the amount of displacement of the child seat relative to the vehicle seat after the impact, or the movement displacement of the child seat caused by the reaction caused by the displacement after the impact, etc. . In order to achieve high impact performance, it is desirable that the child seat be securely fixed to the seat of the vehicle. In the fixing of the child seat, usually, a seat belt of a seat belt device provided in the vehicle seat is used. The seat belt device provided in the vehicle seat includes a seat belt, a tongue having a tongue and groove with a seat belt inserted therein, and a buckle for attaching and detaching the tongue and groove.

In this regard, referring to FIG. 4, as described above, the child seat 1 is formed with a band engaging projection 27 at the rear portion of the base portion 21 of the receiving table 20. The belt engaging projection 27 is disposed at a position that can be engaged with the buckle or the buckle 91 of the seat belt device from the rear side in a state where the receiving base 20 is attached to the vehicle seat. Set. In other words, the band engaging projection 27 is formed to have a certain length, and can correspond to the position of the tongue or the buckle 91 which is different depending on the vehicle type. Further, the band engaging projection 27 may be a groove-shaped belt engaging groove as long as it can be engaged with the buckle or the buckle 91 of the seat belt device.

The buckle or buckle 91 of the seat belt device is usually disposed near the seat surface of the vehicle seat, and has higher rigidity than the seat belt of the seat belt device. Therefore, the buckle or buckle 91 of such a seat belt device is engaged with the receiving base 20 of the child seat 1, in particular, with the engaging projection 27 or the engaging groove formed in the lower portion of the receiving base 20, Thereby, the receiving table 20 can be fixed more firmly. As a result, higher impact resistance can be achieved.

In addition, the engaging projection 27 or the engaging groove is preferably formed such that the buckle or the buckle 91 is engaged with the recess between the receiving base 20 and the engaging projection 27 or perpendicular to the longitudinal direction of the engaging groove The cross-sectional shape forms an acute angle so that the tongue or the buckle 91 does not deviate or loosen and can be more reliably engaged. Further, the band engaging projection 27 or the band engaging groove may not be the engaging tongue or the buckle 91, but may be a seat belt of the seat belt device. At this time, by fixing the lower portion of the receiving table 20 of the child seat 1, the child seat can be fixed more securely than the conventional child seat. Further, the band engaging projections 27 may be formed separately from the receiving table 20.

The above-mentioned belt engaging projection 27 or the belt engaging groove can be applied not only to a child seat in which the seat body can be tilted and rotated for the receiving platform, but also suitable for the seat body to be fixed to the receiving body. The type of the table or the seat body is mounted to the docking station in a detachable configuration.

The child seat 1 is for suppressing the seat body 30 from the receiving table 20 The amount of displacement, which achieves higher impact resistance, with multiple support points for impact. That is, for example, when the vehicle hits an object from the front, the entire child seat 1 receives an inertial force toward the front. At this time, the seat body 30 is not fixed by the vehicle seat belt with respect to the receiving base 20 being fixed by the vehicle seat belt. Therefore, the seat body 30 is displaced forward, but the seat body 30 abuts against the receiving base 20 at the support point and is supported, whereby the displacement amount of the seat body 30 can be suppressed.

In this regard, referring to FIG. 10, as described above, the child seat 1 is engaged with the upper end of the upper connecting rod 43 by the engagement guide member 44 to form the support point A. That is, when the entire child seat 1 receives an inertial force toward the front due to the impact of the vehicle, the front ends of the upper connecting rods 43 disposed directly on the receiving table 20 side of the vehicle seat are supported rearward. The upper portion disposed on the seat body 30 side is engaged with the guide member 44. As a result, the displacement of the seat body 30 with respect to the front of the receiving base 20 can be suppressed when the vehicle hits the object.

Similarly, the impact support surface 44b which is attached to the outer peripheral surface of the upper side of the seat body 30 by the engagement guide member 44, and the support wall surface 28a which is inside the front end part of the receiving base 20 are formed, and the support point B is formed. Further, the lower portion of the seat body 30 is engaged with the annular upper surface 40d of the guiding member 40 (Fig. 8) and the lower end portion of the supporting wall 23a constituting the main body housing opening 23 of the receiving base 20, forming a support. Point C. The support point C is shown in Fig. 10 as the rear end portion of the lower end portion of the support wall 23a of the receiving table 20, and the rear end portion of the upper portion 40d of the lower portion of the engaging guide member 40.

The support point C may also be due to the falling position of the seat body 30. The left and right portions of the lower end portion of the annular support wall 23a of the receiving table 20 and the left and right portions of the upper surface 40d of the lower portion of the engaging guide member 40 are engaged. That is, the upper surface 40d of the lower engaged guide member 40 can form a support point C with the lower end portion of the support wall 23a of the receiving base 20 in any of the lowered positions, and the lower portion is engaged with the guide member 40. The diameter is formed larger than the width L (Fig. 5) in the lateral direction of the body housing opening 23 of the receiving base 20. Thereby, in the child seat 1, the seat main body 30 accommodated in the main body accommodation opening 23 can be prevented from slipping out from the receiving base 20.

The child seat 1 can particularly inhibit the displacement of the seat body 30 relative to the receiving table 20 by having the support points A, B, C, that is, the forward movement of the seat body 30 relative to the receiving table 20 can be suppressed. . As a result, higher impact resistance can be achieved. Further, since the support points A, B, and C are disposed at the lower portion of the seat lower portion 31 of the child seat 1 and the rising portion 22 of the receiving base 20, the receiving base 20 can support the seat body 30 more stably. Further, the receiving table 20 supports the seat body 30 with a plurality of support points A, B, and C, whereby the impact can be dispersed, so that the material forming the receiving base 20 and the seat body 30 can be changed from metal to the like. Lightweight resin, etc., can also reduce costs.

In addition, the receiving platform 20 and the seat body 30 do not have to be abutted at the support point, and may be slightly separated, and only abut when hitting. Further, the child seat 1 may be configured to have only one support point A, or may be configured to have two support points among the support points A, B, and C, or may be configured to have three support points A and B and C. Further, the support points for achieving high impact resistance are not limited to the above three portions. That is, the portion of the seat body 30 that abuts the receiving platform 20 can be engaged with the guiding member at the upper portion. The front portion and the rear portion of the 44 are arbitrarily configured in a lower portion including the lower portion of the guide member 40 than the lower portion and the rear portion.

The height adjustment mechanism of the child care belt 70 (Fig. 1) will be described with reference to Figs. 19 to 22 . 19 is an enlarged perspective view of the back of the child seat 1, FIG. 20 is an exploded assembly view of a part of the height adjustment mechanism of the child seat belt, and FIG. 21 is a height adjustment mechanism for the child care belt 70 of the child seat 1. FIG. 22 is another view showing the height adjustment mechanism of the child care belt of the child seat 1. In addition, in FIG. 19, the back surface board 68 mentioned later is abbreviate|omitted.

In order to securely restrain the infant to the child seat 1, the child seat 1 has a child care belt 70 corresponding to the width of the seat belt provided in the vehicle seat. The child care belts 70 are respectively disposed on the left and right sides of the front side of the backrest portion 32 of the seat body 30, and the left and right child care belts 70 are fastened to the front side of the trunk of the infant. Therefore, the child care belt 70 extends from the rear of the backrest portion 32 of the seat body 30, penetrates the backrest portion 32, and extends forward, and extends downward through the seating surface, that is, the seat lower portion 31, in the lower portion of the seat. The part below the 31 is fixed.

The position from the seating surface of the seat body 30 to the portion of the backrest portion 32 through which the child guard belt 70 passes, that is, the height of the child care belt 70, must be adjusted in accordance with the seat height of the infant. Therefore, the child seat 1 has a height adjustment mechanism for the child care belt 70 in order to appropriately adjust the height of the child care belt 70.

Therefore, the backrest portion 32 of the seat body 30 is formed with the upward facing portion 32 Two openings 36 extending in the lower direction, that is, in the height direction. These openings 36 are formed to be bilaterally symmetrical with respect to the pillar portion 37 at the center of the backrest portion 32, and are formed in a range required for the height of the child care belt 70 in the height direction. Through the openings 36, a moving portion 61 is slidably attached to the backrest portion 32 in the height direction, and the moving portion 61 includes the above-described head plate 60 disposed in front of the backrest portion 32.

The moving portion 61 has a head plate 60 disposed on the front surface of the backrest portion 32, and a rotation support member 62 disposed on the back surface of the backrest portion 32 and attached to the two openings 36 of the head plate 60 through the backrest portion 32, for rotation The first engaging member 63 that is attached by the support member 62 and the second engaging member 64 that is attached to the first engaging member 63. In addition, in FIG. 20, the rotation support member 62, the first engagement member 63, and the second engagement member 64 are slightly enlarged and drawn with respect to the backrest portion 32 and the head plate 60 in order to make it clear. Further, since the head plate 60 holds the child care belt 70 through the slot opening 60a, the head plate 60 constitutes the belt holding member, but may be configured to be held by another member.

In the head plate 60, in order to insert the child care belt 70, two groove openings 60a having substantially the same width as the opening 36 are formed at positions corresponding to the two openings 36 of the backrest portion 32, respectively. A mounting portion 60b that protrudes rearward through the opening 36 of the backrest portion 32 is formed above the groove opening 60a and at the center of the head plate 60. A beam-shaped engaged beam 60c that protrudes rearward through the opening 36 of the backrest portion 32 is formed below the groove opening 60a and at the center of the head plate 60. At the front end of each of the engaged beams 60c, an engagement hole 60d penetrating in the vertical direction is formed.

On the left side of the slot opening 60a on the left side and the right side of the slot opening 60a on the right side, a flat support plate 60e that protrudes rearward through the opening 36 of the backrest portion 32 and that is deployed in the height direction is formed. A recess 60f for accommodating a columnar engagement rod 65 to be described later is formed in the support plate 60e. Further, two vent openings 60g that are always open to the respective openings 36 regardless of the height position of the head plate 60 are formed below the respective groove openings 60a.

The rotation support member 62 has a cover 62a, a rectangular flat protective wall 62b that protrudes upward from the cover 62a, and a flat first knob 62c that protrudes rearward from the cover 62a. The cover portion 62a is attached to the mounting portion 60b (FIG. 19) of the head plate 60 that protrudes through the respective openings 36 of the backrest portion 32, whereby the head plate 60 and the rotation support member 62 can be integrally attached. At this time, the pillar portion 37 of the abutting portion 32 is disposed between the head plate 60 and the rotation support member 62. The protective wall 62b prevents the operator's hand from hitting the pillar portion 37 of the seat body 30 when the moving portion 61 is operated.

The first engaging member 63 has a box-shaped body member 63a. A rectangular opening 63b is formed on the back surface of the body member 63a. The upper portion of the main body member 63a is attached to the cover 62a of the rotation support member 62 so that the first engagement member 63 is rotatable about a rotation axis extending in the lateral direction. Further, in the lower portion of the main body member 63a, a cylindrical engaging rod 65 extends toward the left and right outer sides. The engaging rod 65 has a reinforcing rod 65a inserted therein for reinforcement in the inside. The reinforcing rod 65a is formed of a metal such as carbon steel, but is not limited thereto.

In the back surface of the backrest portion 32, on the pillar portion 37, the left side is opened The left side of the opening 36 and the right side of the right opening 36 are formed with an engaged curved surface portion 38. The engaged curved surface portion 38 has a configuration in which one portion of the cylindrical surface extending in the lateral direction is formed, and the concave curved surface is formed to be wide in order to easily accommodate the cylindrical engaging rod 65, and is arranged in the horizontal direction. Further, a plurality of them are arranged at equal intervals in the height direction.

By engaging the engagement bar 65 of the first engagement member 63 with the concave curved surface of any one of the engagement curved surface portions 38, the height position of the head plate 60 with respect to the backrest portion 32 can be adjusted. At this time, the engagement bar 65 of the first engagement member 63 that has been engaged with the engaged curved surface portion 38 is also housed in the support plate of the head plate 60 that slides in the height direction together with the first engagement member 63. Inside the recess 60f of 60e. Further, the first engaging member 63 is provided with the right and left torsion springs 63c integrally formed in the inside of the rotation supporting member 62, and is engaged with the engaged curved surface portion 38 of the engaging rod 65 and the abutting portion 32. Potential energy in the direction of rotation.

The second engagement member 64 is a plate-shaped member that is slidable in the vertical direction inside the main body member 63a of the first engagement member 63, and is provided with a potential energy directed downward by the coil spring 64a. At the lower end portion of the second engaging member 64, a pair of engaging pins 66 projecting downward from the main body member 63a of the first engaging member 63 are formed on the left and right. Each of the engaging pins 66 is inserted into the engaging hole 60d of the engaged beam 60c that protrudes from the head plate 60 through the opening 36, thereby engaging the head plate 60. In addition, the second engagement member 64 has a flat second knob 64b that passes through the rectangular opening 63b of the first engagement member 63 and protrudes rearward.

Referring to Figure 21, the height of the child care belt 70 is adjusted. Operation. 21 is a view for explaining the height adjusting mechanism of the child care belt 70 of the child seat 1 as described above, and is a longitudinal cross-sectional view through the center of the seat body 30, that is, the center of the moving portion 61 in the width direction. First, the first handle 62c of the rotation support member 62 and the second handle 64b of the second engagement member 64 are held simultaneously, and the second handle 64b is pulled upward in the direction of the first handle 62c (FIG. 21(a) ). That is, the second engaging member 64 is pulled upward with respect to the first engaging member 63. This operation is performed, for example, by placing the thumb on the upper surface of the first handle 62c, and touching the index finger and the middle finger to the lower surface of the second handle 64b and pulling it upward. The second engaging member 64 is pulled upward with respect to the first engaging member 63, whereby the engaging pin 66 of the second engaging member 64 and the engaged arm 60c of the head plate 60 can be released. Engagement between the holes 60d. As a result, the first engagement member 63 is in a state of being rotatable relative to the rotation support member 62 (FIG. 21(b)).

Further, when the second handle 64b of the second engagement member 64 is continuously pulled upward, the first engagement member 63 rotates with respect to the rotation support member 62. Thereby, the engagement between the engagement bar 65 of the first engagement member 63 and the engaged curved surface portion 38 on the back surface of the back contact portion 32 can be released. As a result, the head plate 60 is in a state of being slidable in the height direction with respect to the backrest portion 32 (FIG. 21(c)). In this state, the head guard 60 of the child care belt 70 is inserted into the slot opening 60a to slide in the height direction with respect to the backrest portion 32, so that the child care belt 70 can be slid to a desired height.

Here, when the second engagement member 64 is pulled upward with respect to the first engagement member 63 and the engagement of the engagement pin 66 is released, the first engagement member 63 is made to be opposite to the rotation support member 62. Rotate to limit the 2nd card The sliding of the engaging member 64 with respect to the first engaging member 63. This will be described with reference to Fig. 22 . 22 is a view showing the child care belt height adjusting mechanism of the child seat 1 as described above, and is a longitudinal cross-sectional view including the side surface of the second engaging member 64. In FIG. 22, members other than the first engagement member 63 and the second engagement member 64 are omitted.

Referring to Fig. 22, a locking projection 64c (see also Fig. 20) is formed on the side surface of the second engaging member 64, and a locking recess 62d is formed inside the casing 62a of the rotation supporting member 62. In the state of FIG. 22( a ), the second engagement member 64 is pulled upward with respect to the first engagement member 63 ( FIG. 22( b )), and then the first engagement member 63 is rotated relative to the rotation support member 62 . And rotate. Thereby, the locking projection 64c of the second engaging member 64 is engaged with the locking recess 62d of the rotation support member 62 (FIG. 22(c)). As a result, the sliding of the second engaging member 64 with respect to the first engaging member 63 is restricted.

Therefore, even in this state, the pulling force of the second handle 64b of the second engaging member 64 is weakened, and the engaging pin 66 does not protrude further by the force of the potential of the coil spring 64a. In other words, the second engaging member 64 that has been slid upward is configured to be securely configured in a state in which the engaging rod 65 of the first engaging member 63 is not engaged with the engaged curved surface portion 38 of the backrest portion 32. The second engaging member 64 does not return to the original position.

After the child care belt 70 is slid to the desired height, the child care belt 70 is fixed at the height as long as one of the above-described series of actions is reversed. In other words, the first engagement member 63 is rotated with respect to the rotation support member 62, and the engagement bar 65 of the first engagement member 63 is engaged with the engaged curved surface portion 38 of the back contact portion 32. Thereby, the card of the second engaging member 64 can be released. The engagement between the stopper projection 64c and the locking recess 62d of the rotation support member 62 is performed. Then, the second engaging member 64 is slid downward with respect to the first engaging member 63, and the engaging pin 66 of the second engaging member 64 and the engaging hole 60d of the engaged beam 60c of the head plate 60 are stuck. Hehe. Since these operations are assisted by the torsion spring 63c and the coil spring 64a, the force for imparting the potential energy can be easily performed.

The height adjustment mechanism of the child care belt 70 has two engagements of the engagement of the second engagement member 64 with the head plate 60 and the engagement of the first engagement member 63 with the backrest portion 32. Even if an impact is applied to the entire child seat 1, the engagement on both sides does not come loose. In other words, the engagement of the second engaging member 64 with respect to the head plate 60 is released by the upward movement, and the engagement of the first engaging member 63 with the backrest portion 32 is released. The rotation direction, that is, the movement away from the abutting portion 32 is performed. Therefore, the direction of the force required to release the engagement is slightly orthogonal.

Further, the engagement of the second engaging member 64 with respect to the head plate 60 and the release of the first engaging member 63 with respect to the backrest portion 32 are performed by the second handle 64b of the second engaging member 64. A series of continuous actions of pulling up. In other words, by applying a force to the second handle 64b of the second engaging member 64 in the same upward direction, the two-stage engagement can be released. Therefore, the above-described height adjusting mechanism of the child care belt 70 is configured such that it is difficult to unintentionally release the engagement, but it is easy to consciously release the engagement.

Further, since the engaged curved surface portion 38 is formed by the pillar portion 37 in the center of the backrest portion 32, the strength of the backrest portion 32 can be maintained. Moreover, the concave curved surface of the back surface portion 38 that is engaged with the curved surface portion 38 is formed as Since the alignment bars 65 of the first engaging member 63 are not engaged with one course, they are prevented from being engaged with the engaged curved surface portions 38 of different heights from each other. Concave surface.

Further, the height adjustment mechanism of the child care belt 70, that is, the movement mechanism, may be any configuration as long as it can be operated by the operation described with reference to FIG. 21. In other words, the moving mechanism is configured such that the sliding direction is parallel to the direction of the force applied to the second engaging member, and the engagement is released by the sliding of the second engaging member, and then the rotation of the first engaging member is performed. The engagement can be released and the slidable state can be arbitrarily configured. Further, the height adjusting mechanism described above can be applied not only to the field of child seats, but also to other fields where there is a need to safely implement the operation of the moving mechanism.

In addition, the child care belt 70 is appropriately adjusted in height in response to the height of the infant by the height adjustment mechanism described above, and the tightness of the child care belt 70, that is, the backrest portion, is appropriately adjusted in accordance with the body shape of the infant. 32 Length extending toward the front.

The adjustment of the length of the child care band 70 using the adjustment belt 75 will be described with reference to Figs. 23 and 24 . 23 is a perspective view showing the adjustment belt 75 of the uppermost position of the child seat 1, and FIG. 24 is a perspective view showing the adjustment belt 75 of the lowermost position of the child seat 1. 23 and 24 are perspective views of the seat body 30 of the child seat 1 as seen from below.

The left and right child care belts 70 are connected to the rear side of the backrest portion 32 of the seat body 30, and thus are constituted by one belt. Further, the child care belt 70 is on the rear side of the backrest portion 32 of the seat body 30, and has a width wider than one. One end of the adjustment band 75 is connected. That is, one end of the adjustment belt 75 is folded in half and is stitched to coincide with the folded back portion. As a result, at one end of the adjustment belt 75, an annular portion 75a is formed. The baby care belt 70 is inserted into the annular portion 75a. Therefore, the annular portion 75a of the belt 75 is adjusted to form a joint portion with the child guard band 70. The adjustment belt 75 is formed by weaving a material generally used for a vehicle seat belt, such as polyester fiber, but is not limited thereto.

The adjustment belt 75 extends downward along the backrest portion 32 of the seat body 30, from the vicinity of the lower end portion of the seat body 30, that is, the opening 31c formed at the lower portion of the rear side surface of the cylindrical portion 31b of the seat lower portion 31 ( Referring also to Figure 7), it enters the interior space 35. Next, the adjustment belt 75 that has entered the internal space 35 of the seat body 30 is a belt supporting protrusion 33e that protrudes upward by being formed on the bottom surface of the internal space 35, and is bent at an acute angle toward the inside. Above, it extends to the vicinity of the lower surface of the seat panel 34.

Next, after the adjustment belt 75 extends in the internal space 35 toward the front and extends in parallel with the seat bottom surface 33, the opening 31d (see also FIG. 7) is formed from the upper portion of the front side surface of the cylindrical portion 31b of the seat lower portion 31. Leave outside the internal space 35. Next, the adjustment belt 75 extends from the opening 31e formed on the front side surface of the truncated cone portion 31a of the seat lower portion 31 to the upper portion of the seat lower portion 31. Then, the adjustment belt 75 passes through the belt adjustment tool 76 disposed behind the operation table 55 of the operation mechanism attached to the front portion of the seat lower portion 31, and extends toward the front of the seat body 30 (FIG. 1).

The belt adjustment tool 76 can be used to lock and release the adjustment belt 75 by a well-known mechanism. When the adjustment belt 75 is locked by the belt adjustment tool 76, the adjustment belt 75 cannot be moved in the front-rear direction with respect to the belt adjustment tool 76. move. On the other hand, when the lock of the belt adjuster 76 is released, the adjustment belt 75 can be moved in the front-rear direction with respect to the belt adjuster 76.

Next, the length adjustment of the child care belt 70 will be described. The length adjustment of the child care belt 70 is performed in a state in which the belt adjustment tool 76 is released. When it is desired to lengthen the child care belt 70 extending forward of the backrest portion 32, the child care belt 70 extending forward of the backrest portion 32 can be lengthened by pulling it forward or upward. Finally, the child care belt 70 can be pulled until there is no excess on the back side of the backrest portion 32 of the seat body 30. At this time, the length of the child care belt 70 extending toward the front of the backrest portion 32 is the largest, and the annular portion 75a of the adjustment belt 75 coupled to the child care belt 70 is located at the uppermost position (Fig. 23).

The uppermost position of the adjustment belt 75 refers to a position at which the annular portion 75a corresponds to a portion formed by the slot opening 60a of the head plate 60 of the child care guard 70. Therefore, the uppermost position of the adjustment belt 75 varies depending on the height adjusted by the height adjustment mechanism of the child care belt 70.

On the other hand, when it is desired to shorten the length of the child care belt 70 extending forward of the backrest portion 32, the portion of the adjustment belt 75 (Fig. 1) extending toward the front of the seat body 30 can be forwardd. Pull it to make it shorter. Finally, the adjustment belt 75 can be pulled until the annular portion 75a of the adjustment belt 75 coupled to the child guard band 70 is disposed in the vicinity of the opening 31c of the seat lower portion 31. At this time, the length of the child care belt 70 extending toward the front of the backrest portion 32 is the shortest, and the annular portion 75a of the adjustment belt 75 coupled to the child care belt 70 is located at the lowermost position (Fig. 24).

The lowermost position of the adjustment belt 75 refers to the position of the annular portion 75a in the vicinity of the opening 31c of the seat lower portion 31. Therefore, adjust the bottom of the belt 75 The position is a position fixed to the opening 31c of the seat lower portion 31.

According to the above, the length adjustment of the child care belt 70 is performed by pulling the child care belt 70 extending toward the front of the backrest portion 32 or the portion of the adjustment belt 75 extending toward the front of the seat body 30, whereby Adjust the tightness of the baby care belt 70 that responds to the baby's body shape.

In the child seat 1, the adjustment belt 75 extends to the vicinity of the lower end portion of the rear side of the seat body 30, that is, the opening 31c formed at the lower portion of the rear side surface of the cylindrical portion 31b of the seat lower portion 31, and then enters the internal space 35. Inside. Next, the adjustment belt 75 is extended upward by the belt support protrusion 33e, bent at an acute angle. Therefore, the adjustment belt 75 faces the belt adjustment tool 76, not through the shortest distance, but around the path of the bypass. Therefore, in the child seat 1, the uppermost position of the adjustment belt 75 can be ensured by arranging the lowermost position of the adjustment belt 75 in the vicinity of the lower end portion of the lower seat body 30 than the conventional child seat. The distance between the lowermost position and the lower position is longer. As a result, the range of length adjustment of the child care belt 70 can be made wider.

Further, in order to make the adjustment of the adjustment belt 75 smooth, a pulley may be disposed at a portion that is in contact with the seat body 30, for example, at an upper portion of the opening 31c. Moreover, the adjustment belt 75 can also be passed through the inside of the seat body 30, via the outside thereof, that is, via the underside of the seat body 30.

On the back side of the backrest portion 32 of the seat body 30, a harness panel 68 is attached. 25 is an enlarged perspective view of the back of the child seat 1, and FIG. 26 is a perspective view of the back panel 68 of the child seat 1. The back panel 68 can achieve the effect of covering and storing the excess child care belt 70 and the adjustment belt 75 disposed on the rear side of the backrest portion 32 of the seat body 30 in the backrest portion. The back of the 32, so that it does not interfere with the use. Further, the back panel 68 can achieve an effect of blocking a portion of the moving portion 61 and the engaged curved surface portion 38 formed on both sides of the opening 36 of the backrest portion 32 of the seat body 30 so as not to be exposed.

As shown in the longitudinal cross-sectional view of FIG. 9, the back panel 68 is disposed so as to extend in the height direction in the central portion in the width direction of the seat body 30, and is fitted to the seat body 30. The back panel 68 has a panel upper portion 68a and a panel lower portion 68b. The back panel 68 is integrally formed by being molded by injection molding from a resin material such as polypropylene. In particular, a portion of the boundary between the panel upper portion 68a of the back panel 68 and the panel lower portion 68b is formed with a hinge 68c which is formed thinner than other portions and can be repeatedly bent without being damaged. However, the back panel 68 can also be omitted by bending the hinge 68c with its flexibility. Further, the child care belt 70 and the adjustment belt 75 are housed in a housing space 68d (FIG. 9) between the seat body 30 and the back panel 68.

The upper end portion of the back panel 68 is engaged with the backrest portion 32 of the seat body 30. However, by releasing the engagement, the panel upper portion 68a can be bent rearward about the hinge 68c, and the seat body 30 can be The storage space 68d between the back panels 68 is open. That is, the back panel 68 can be partially separated from the backrest portion 32. For example, when the excess portion of the child care belt 70 disposed on the back side of the seat body 30 is adjusted, the panel upper portion 68a of the back panel 68 can be bent and opened to facilitate work.

Further, in the panel upper portion 68a of the back panel 68, an opening 68e is formed in the height direction in the central portion in the width direction. The width of the opening 68e is larger than the width of the pillar portion 37 of the backrest portion 32 of the seat body 30. Therefore, the two openings 36 of the backing portion 32 pass through the opening 68e of the back panel 68. Partially exposed. As a result, in the front-rear direction of the backrest portion 32 of the seat body 30, the two openings 36 of the backrest portion 32 and the vent opening 60g of the head plate 60 (FIG. 20) can be passed through to ensure the air permeability so that the ride is carried out. Infants and young children do not feel uncomfortable. Further, by forming the opening 68e in the back panel 68, the moving portion 61 can be operated in a state where the back panel 68 is attached. That is, the first handle 62c of the rotation support member 62 and the second handle 64b of the second engagement member 64 can be accessed through the opening 68e of the back panel 68.

The child care belt 70 will be described with reference to Figs. 27 to 29 . Figure 27 is a top view of a portion of the child care belt 70, Figure 28 is a side view of the child care belt 70 of Figure 1 in an extended state, and Figure 29 is a side view of the child care belt 70 of Figure 1 in a bent state.

The child care belt 70 used in the child seat 1 is formed by superposing a plurality of flexible belts 71 having a strip shape, for example, two sheets 71a and 71b. Each of the strips 71a and 71b is formed by weaving a material generally used for a vehicle seat belt, for example, polyester fiber. The strips 71a and 71b are sewn together along a plurality of lines extending in the longitudinal direction, for example, two lines 71c.

When the child care belt 70 is bent, after the force for bending it is released, the bending state is maintained in violation of gravity. That is, when the superposed strip 71 is bent, the radius of curvature of the strip 71a on the inner side of the bend is smaller than the radius of curvature of the strip 71b on the outer side of the bend. Because of the difference in the radius of curvature, the outer surface of the strip 71a facing the inner side and the inner side of the strip 71b on the outer side are elongated in the circumferential direction of the curve, for example, the longitudinal direction of the strip 71, and Deviation. Then, when you bend it When the force is released, the stretched outer strip 71b of the child care belt 70 returns to the original state, but the outer side surface of the inner strip 71a and the inner side of the outer strip 71 may be due to frictional resistance. The card is locked. As a result, the deformed child care belt 70 maintains its shape in violation of gravity after liberating the force that deforms it.

Therefore, even if the parent holds the baby care belt 70 and holds the baby from the child seat, the child care belt 70 maintains the shape in violation of the gravity, so that the infant can not be hindered after riding. Further, since the strips 71a and 71b are formed of soft materials such as polyester fibers, it is safe even if the infant or the parent touches or hits the baby guard 70.

Further, when the child care belt 70 is deformed, the belts 71a and 71b can be loosely sewn in order to cause a larger deviation between the two sheets 71a and 71b. Further, the child care belt 70 may be maintained in shape by inserting a wire or a metal plate or the like which can maintain the deformed shape, not by frictional resistance. Further, the entire child care belt 70 may have a configuration in which the shape is maintained as described above, or may be a partial configuration. Further, a cushioned child care belt cover 77 (Fig. 1) may be wound on the portion of the child care belt 70 that is in contact with the infant. At this time, the child care cover 77 may be configured to maintain the shape as described above. Further, the above-described child care belt 70 can be applied not only to the field of child seats, but also to other fields in which it is necessary to maintain the shape of the belt in violation of gravity.

A method of attaching the child care belt 70 to the seat body 30 will be described with reference to Figs. 7 and 30. Figure 30 is a child care belt 70 of the child seat 1 Front view. In particular, the child care belt 70 shown in Fig. 30 is provided with a fastening portion 78 (Fig. 1) which is fastened to the left and right child care belts 70 by a fastening mechanism at one end thereof, and is provided at the baby. A baby care belt 70 in the stock between the children's shares. In the method of mounting the seat body 30, the left and right child care belts 70, and the child care belts 70 of the strands are the same. As described above, the child care belt 70 and the child care belt 70 extending from the backrest portion 32 of the seat body 30 are portions that are fixed to the lower portion of the seat body 30 so as to penetrate the seat lower portion 31 downward. Therefore, as shown in FIG. 7, the seat lower portion 31 has a mounting opening 31f formed in the left and right and front portions as a rectangular through hole, and is used as a mounting portion for attaching the child care belt 70.

Further, the front end of the strip 71 which constitutes the child's protective band 70 which penetrates the seat lower portion 31 of the seat body 30 is folded in half, and is stitched to overlap with the folded portion. As a result, at the front end of the child care band 70, an annular portion 72 formed in a ring shape is formed.

Next, a cylindrical fixing rod 73 is inserted into the annular portion 72 of the child guard band 70 that penetrates the seat lower portion 31 of the seat body 30. The fixing rod 73 is formed by cutting a material such as carbon steel, for example, a material of a round bar, but is not limited thereto. The fixing rod 73 is formed larger than the mounting opening 31f of the seat lower portion 31 through which the child guard band 70 penetrates. That is, the length of the cylindrical fixing rod 73 is larger than the lateral size of the rectangular mounting opening 31f, and the diameter of the fixing rod 73 is larger than the longitudinal dimension of the mounting opening 31f. Therefore, in a state where the fixing rod 73 is inserted into the annular portion 72 of the child guard band 70, the child care belt 70 is not released from the seat body 30. The fixing rod 73 inserted into the annular portion 72 of the child guard band 70 is formed by the seat body 30. The engaging claw 31g in the vicinity of the mounting opening 31f is fixed by snap fit.

Since the child care belt 70 is securely fixed by the snap-fit fitting of the fixing bar 73, it does not fall below the seat body 30 and hinders use. Further, the fixing rod 73 may have a rod shape, and does not necessarily have to be a cylindrical shape, that is, a circular cross section. It is also possible to configure the fixing rod 73 as, for example, a cross section having a polygonal shape such as a square shape and a hexagon shape.

The fixing rod 73 for fixing the child care belt 70 is cut from the rod-shaped material, whereby the raw material cost and the processing cost can be made very cheap. Further, since the structure of the fixing rod 73 is simple, the strength is also excellent. Further, the child care belt 70 uses the fixing bar 73 for fixing the seat body 30, and since it is simply fitted by a snap-on type, the mounting work is also simple.

The cover mechanism 80 will be described with reference to Figs. 31 and 32. 31 is a perspective view of the upper portion of the child seat 1, and FIG. 32 is an exploded assembly view of the rotation locking mechanism 81 of the cover mechanism 80 of the child seat 1.

The cover mechanism 80 is attached to the head plate 60, and the entire cover mechanism 80 slides in accordance with the vertical direction of the head plate 60. The cover mechanism 80 includes a rotation locking mechanism 81, a cover (not shown) that covers the baby's head, and one fixed cover stay 82 that serves as a skeleton for supporting the cover, two first movable cover stays 83, and a second Movable cover stay 84. The rotation locking mechanism 81 has a pair of stay supporting members 85 attached to the right and left curved portions of the head plate 60, a pair of first rotation locking members 86, and a pair of second rotation locking members 87.

Both ends of the fixed cover stay 82 are fixedly attached to the left and right stay supporting members 85. Both ends of the first movable cover stay 83 are opposite The left and right stay supporting members 85 are rotatably staged by the first rotation locking members 86, and can be attached to the stepwise rotational positions. The both ends of the second movable cover stay 84 are attached to the left and right stay supporting members 85 so as to be rotatable in stages by the second rotation locking members 87.

Therefore, the first movable cover stay 83 and the second movable cover stay 84 can be rotated stepwise toward the front or the rear around the entire rotation axis extending in the lateral direction. Therefore, the cover can be deployed toward the front or folded back. Further, since the first movable cover stay 83 has a larger rotation angle than the second movable cover stay 84, it can be deployed further forward than the second movable cover stay 84.

The first rotation locking member 86 has a first rotation end portion 86a formed in a circular shape. Further, the second rotation locking member 87 has a second rotation end portion 87a formed in a circular shape having the same diameter as the first rotation end portion 86a. The stay supporting member 85 has a circular support portion that is formed to have the same diameter as the first rotational end portion 86a of the first rotation locking member 86 and the second rotation end portion 87a of the second rotation locking member 87. 85a. In the center of the rotation support portion 85a, an elastic beam 85b formed by a U-shaped groove is formed.

The first rotating end portion 86a of the first rotation locking member 86 is disposed on the outer side surface of the elastic beam 85b of the stay supporting member 85, and the inner side surface of the elastic beam 85b of the stay supporting member 85 is disposed on the inner side surface of the elastic beam 85b of the stay supporting member 85. 2 The second rotation end portion 87a of the locking member 87 is rotated. The elastic beam 85b, the first rotation end portion 86a, and the second rotation end portion 87a are rotatably fastened and coupled by inserting a rotation pin 88 at each center.

Two locking concave portions 86b having a concave curved surface are formed on the circumference concentric with the rotation center of the first rotation end portion 86a of the first rotation locking member 86. In the same manner, two locking recesses (not shown) having a concave curved surface are formed on the circumference concentric with the rotation center of the second rotation end portion 87a of the second rotation locking member 87. Further, the outer surface of the rotation support portion 85a of the opposing stay supporting member 85 is on the circumference concentric with the rotation center of the first rotation locking member 86 and the rotation of the first rotation locking member 86. A plurality of locking convex portions 85c (not shown) having a convex curved shape that is locked with the locking concave portion 86b are formed at positions corresponding to the locking recesses 86b in the range. Similarly, the inner side surface of the rotation support portion 85a of the opposing stay supporting member 85 is on the circumference concentric with the rotation center of the second rotation locking member 87 and over the second rotation locking member 87. A plurality of locking convex portions 85c having a convex curved shape that is locked with the locking concave portion 87b are formed at positions corresponding to the locking concave portions 87b of the rotation range.

In order to expand or fold the cover, when the first movable cover stay 83 is slightly rotated relative to the stay supporting member 85, the locking concave portion 86b of the first rotation locking member 86 and the stay supporting member are temporarily released. The locking between the locking projections 85c of 85 is performed. In other words, the locking convex portion 85c of the stay supporting member 85 is disposed between the adjacent locking recesses 86b of the first rotation locking member 86, and the rotation supporting portion 85a of the stay supporting member 85 and the first The first rotation end portions 86a of the rotation locking member 86 are slightly separated from each other. In this state, the elastic force of the elastic beam 85b of the stay supporting member 85 coupled to the first rotating end portion 86a of the first rotation locking member 86 is directed to the rotation supporting portion 85a of the stay supporting member 85. 1 rotating the first rotating end of the locking member 86 86a is in a direction close to each other to give potential energy.

When the first movable cover stay 83 is further rotated about the stay supporting member 85, the locking concave portion 86b of the first rotation locking member 86 is adjacent to the stay supporting member 85 in the rotational direction. The locking convex portion 85c is locked and in a stable state. The force imparting the potential energy of the elastic beam 85b of the stay supporting member 85 also contributes to the locking of the stability. On the other hand, the state in which the locking concave portion 86b of the first rotation locking member 86 and the locking convex portion 85c of the stay supporting member 85 are locked is released, and the state is unstable. Therefore, when the first movable cover stay 83 is rotated, the first rotation locking member 86 is rotated in stages, and the locking can be locked at the stepwise rotation position so that the locking recess 86b and the rotation direction are caused. The locking convex portion 85c of the adjacent stay stay supporting member 85 is locked and in a stable state.

Further, the rotation of the second movable cover stay 84 with respect to the stay supporting member 85 is the same as the rotation of the above-described first movable cover stay 83 with respect to the stay supporting member 85. Therefore, when the second movable cover stay 84 is rotated, the second rotation locking member 87 can be rotated stepwise so that the locking concave portion is locked to the stay supporting member 85 adjacent to the rotational direction. The convex portion 85c is locked and in a stable state.

Since the cover mechanism 80 described above can slide in the vertical direction together with the head plate 60, it is possible to adjust the height with a simple operation in accordance with the height of the infant seated. Further, the locking concave portion 86b of the first rotation locking member 86 and the locking concave portion of the second rotation locking member 87 are formed in a concave curved shape, and the locking convex portion of the supporting stay supporting member 85 is formed. The portion 85c is formed into a convex curved surface, so that the card can be smoothly performed. Stop and release. Therefore, it is possible to realize a rotation locking mechanism that can form a rotation locking mechanism that smoothly rotates and locks even if it is a simple mechanism having a small number of parts.

In addition, one of the two first movable cover stays 83 and the second movable cover stays 84 may be omitted. Thereby, when the child seat is made into a product, the difference of each product model can be simply displayed. Further, the locking concave portion 86b of the first rotation locking member 86 and the locking convex portion may be formed on the side of the second rotation locking member 87, and the locking concave portion may be formed on the side of the stay supporting member 85. Further, the number of the locking convex portions and the locking concave portions can be arbitrarily selected. Further, the locking convex portion and the locking concave portion may have any shape in a range in which they can be locked and released.

The positioning mechanism 110 of the support leg 100 will be described with reference to Figs. 33 to 35. Figure 33 is a perspective view of the positioning mechanism 110 of the support foot 100 of the child seat 1, Figure 34 is a longitudinal sectional view of the center of the positioning mechanism 110 of Figure 33, and Figure 35 is the longitudinal center of the positioning mechanism 110 of Figure 33. Sectional view. In addition, in FIG. 33, in order to make the internal structure of the positioning mechanism 110 clear, a part of the members only draw the outline.

As shown in FIGS. 2 and 3, the support leg 100 extends to the bottom surface of the vehicle supporting the vehicle seat on which the child seat body 10 is mounted, and supports the child seat body 10, that is, the receiving platform 20 from below. The front part. The support leg 100 has a leg portion 101 that is freely expandable and contractible in the longitudinal direction, and a positioning mechanism 110 that is attached to the leg portion 101 and determines the length of the leg portion 101.

The leg portion 101 includes a first tubular member 102 attached to the receiving base 20 and a second tubular member disposed below the first tubular member 102. 103. The upper portion of the second tubular member 103 is inserted into the lower portion of the first tubular member 102, and the length of the leg portion 101 can be adjusted by adjusting the amount of insertion. In the first tubular member 102, one through hole 102a into which a fixing member 117 to be described later is inserted is formed. Further, the second tubular member 103 is formed with a plurality of through holes 103a (FIG. 2) that are disposed along the longitudinal direction and that are selectively inserted into the fixing member 117.

The positioning mechanism 110 is attached to the lower portion of the first tubular member 102 and has a cover 113 including a first cover half 111 and a second cover half 112, a slider 114, and a foot operating lever 115. The first casing half body 111 is attached from the front side of the first tubular member 102, and the second casing half body 112 is attached from the rear side of the first tubular member 102. In other words, the first casing half 111 and the second casing half 112 are fitted to each other from the front and rear sides of the first tubular member 102, and are attached to the first tubular member 102.

In the casing 113 on the side of the first casing half 111, in a direction perpendicular to the longitudinal direction of the leg portion 101, that is, between a direction in which the leg portion 101 penetrating the casing 113 is separated and a direction in which it approaches. A slider 114 is slidably disposed. That is, a plurality of guide walls 111a for guiding the sliding of the slider 114 are formed in the casing 113 on the side of the first casing half 111. A hollow hub portion 111c that protrudes rearward is formed in the inner wall 111b of the front surface of the first casing half body 111, and a coil spring 116 is disposed around the hub portion 111c.

In the upper portion of the slider 114, a recess portion 114a that accommodates the boss portion 111c of the first cover half body 111 and the coil spring 116 is formed. Further, in the concave portion 114a of the slider 114, a columnar guide projection 114b (Fig. 35) that protrudes forward is formed. That is, the slider 114 is housed in the recess 114a of the upper portion thereof. The hub portion 111c of the first casing half 111 and the coil spring 116, and the guide protrusion 114b of the slider 114 are inserted into the hollow hub portion 111c. Further, protrusions 114c are formed on the left and right of the upper portion of the slider 114 (Fig. 34). Further, at a lower portion of the slider 114, a fixing member 117 (Fig. 35) which is formed to protrude rearward is attached. The fixing member 117 can also be formed integrally with the slider 114.

At one end of the leg operation lever 115, an operation piece 115a is formed as an operation portion disposed outside the cover, and at the other end of the foot operation lever 115, it is disposed inside the cover 113 and A pair of coupling portions 115b to which the left and right projections 114c of the slider 114 are coupled. A long hole 115c is formed in each of the joint portions 115b, and the corresponding projection 114c of the slider 114 is disposed therein. Cylindrical rotation support protrusions 115d are formed on the right and left sides of the intermediate portion of the leg operation lever 115, respectively. The foot operating lever 115 is attached to the casing 113 by the left and right rotation supporting projections 115d, whereby it is rotatable about a rotation axis extending in the lateral direction.

In a state where the positioning mechanism 110 has been attached to the leg portion 101, the slider 114 is biased by the coil spring 116 in the direction of the leg portion 101. Therefore, the fixing member 117 is inserted into the through hole 102a of the first tubular member 102 and the one through hole 103a of the second cylindrical member 103, and the sliding of the second tubular member 103 with respect to the first tubular member 102 Is limited. Further, the first tubular member 102, the second tubular member 103, and the fixing member 117 are formed of a metal such as carbon steel, but are not limited thereto.

When adjusting the length of the leg portion 101, first, the operation piece 115a of the foot operation lever 115 is pulled upward, that is, in the upward direction, whereby it is rotated about the rotation axis of the rotation support protrusion 115d. turn. This operation is performed, for example, by holding the first tubular member 102 above the positioning mechanism 110 with the right hand extending from the upper side to the lower side, and hooking the operation piece 115a from below with the thumb of the right hand. Climb up from above. Further, when the operation of rotating the operation piece 115a of the foot operation lever 115 is continued, the operation piece 115a is moved in the direction of the leg portion 101 by the rotational movement.

With the rotational movement of the operation piece 115a like this, the joint portion 115b at the other end of the foot operation lever 115 is rotationally moved in the direction away from the leg portion 101. By the rotational movement of the joint portion 115b, the slider 114 slides along the guide wall 111a in a direction away from the leg portion 101. That is, the joint portion 115b with respect to the foot operation lever 115 is rotated, and the movement of the slider 114 is restricted in the sliding direction by the guide wall 111a. However, the left and right projections 114c of the slider 114 move in the long hole 115c in accordance with the rotational position of the corresponding coupling portion 115b, whereby the rotation of the coupling portion 115b can be prevented without hindering the rotational movement of the coupling portion 115b. The motion is transformed into a sliding motion of the slider 114. In other words, the shape of the long hole 115c of the connecting portion 115b is determined such that the change of the motion can be smoothly performed.

The sliding member 114 slides in the direction away from the leg portion 101, and the fixing member 117 integrally attached to the slider 114 is pulled away from the through hole 102a of the first cylindrical member 102 and the through hole of the second cylindrical member 103. 103a, the length adjustment of the foot 101 can be performed. At this time, although the first tubular member 102 is held by the right hand, the left hand can be used freely.

Next, for example, the second tubular member 103 is slid with respect to the first tubular member 102 by using the left hand, whereby the leg portion 101 is adjusted to a desired state. The length of the through hole 102a of the first tubular member 102 and any one of the through holes 103a of the second cylindrical member 103 are aligned. In this state, when the force applied to the operation piece 115a of the foot operation lever 115 is released, the slider 114 slides in the direction of the leg portion 101 by the force of the potential of the coil spring 116. As a result, the fixing member 117 of the leg operating lever 115 is inserted into the through hole 102a of the first cylindrical member 102 and the through hole 103a of the second cylindrical member 103, and the operation piece 115a of the foot operating lever 115 is returned. original position. That is, it can be said that the slider 114 is slidable between the fixed position where the fixed leg portion 101 is stretched and the released position.

Regarding the positioning mechanism 110 of the support leg 100, the following is performed: when the foot operating lever 115 is rotated in the direction in which the operating piece 115a approaches the leg 101, the connecting portion 115b moves in a direction away from the leg 101 to slide the slider 114. To the release position. On the other hand, when the leg operating lever 115 is rotated in the direction in which the operating piece 115a is separated from the leg portion 101, the connecting portion 115b moves in the direction approaching the leg portion 101 to slide the slider 114 to the fixed position.

In the positioning mechanism 110 described above, since the one side of the leg portion 101 can be gripped by one hand and the sliding position of the slider member 114 can be released, the other hand can be freely used, so that the foot can be held while being held. On the other side of 101, the length of the foot 101 is adjusted with a simple operation. Further, since the operation piece 115a of the foot operation lever 115 must first be operated upward in order to adjust the length of the leg portion 101, even if the infant steps on the operation piece 115a of the foot operation lever 115 from above, it will not Inadvertently, the slider 114 is in the released position.

However, as described above, the child seat 1 is a seat belt type child seat Therefore, the seat belt 1 is fixed to the vehicle seat, and the seat belt of the seat belt of the vehicle seat is used.

Figure 36 is another perspective view of the receiving table 20 of the child seat 1 of Figure 1 Figure 37 is a perspective view of the lower half 150 of the receiving station 20 of Figure 36. The receiving table 20 is formed by fitting the lower half 150 formed separately with the upper half 151. That is, the lower half 150 is formed by the bottom surface of the base portion 21 including the cylindrical curved surface 25 and the back surface of the rising portion 22, and the upper half 151 is formed to be formed on the upper surface of the base portion 21 including the receiving table support surface 24. The front part of the front part 22 is.

In Fig. 36, a conventional gripping mechanism for gripping a vehicle seat belt, that is, a car seat belt fixing member 130, which is omitted in the above description, is shown. Since the car seat belt fixing member 130 is disposed on the front surface of the rising portion 22 of the receiving table 20, that is, the left and right sides of the front surface of the upper half body 151, the seat belt disposed on either side of the left and right sides of the child seat 1 can be borrowed. Clamping is performed by the corresponding car seat belt fixing member 130. Therefore, the seat belt that is extended by the front surface of the rising portion 22 is held by the car seat belt fixing member 130, whereby the child seat 1 can be firmly attached to the vehicle seat. In addition, in FIG. 36, the car seat belt fixing member 130 on the right side is omitted.

Next, an ISOFIX type child seat manufactured in accordance with the ISOFIX or ISO-FIX specifications will be described.
