Therefore, after the rotary operation, when the rotary operation lever 55b is released, the rotary operation lever 55b will return to the rear position by the potential force imparted by the coil spring 54b, and each front end of the rotary lock pin 51 will also be inserted into the lock Inside the ditch 25b.

Referring to FIGS. 12 and 13, the reclining mechanism and the rotating mechanism of the child seat 1 will be described. FIG. 12 is a diagram illustrating the reclining mechanism and rotation mechanism of the child seat 1, and FIG. 13 is another diagram illustrating the reclining mechanism and rotation mechanism of the child seat 1. In FIGS. 12 and 13, each structure is shown schematically.

As described above, the seat body 30 includes the lower engaged guide member 40, the upper engaged guide member 44, and the cover member 45. In addition, the lower connecting rod 41 and the upper connecting rod 43 connected via the rod connecting member 42 will engage and connect the lower engaged guide member 40 and the upper engaged guide member 44 at the same time. A pair of upper connecting rods 43 respectively penetrate the corresponding guide grooves 22b of the receiving platform 20, and the lower connecting rod 41 and the lower connecting rod 41 are guided by the rod connecting member 42 abutting the inner side surface of the inclined surface 22a of the receiving platform 20 The upper connecting rod 43 slides in the front-rear direction and restricts movement in the lateral direction.

In FIG. 12, the seat body 30 is located in the reclining position corresponding to the rear locking hole 25a among the three locking holes 25a. That is, the seat body 30 engages with the locking hole 25a the reclining lock pin 50 protruding downward from the seat body 30 through the lower engaging guide member 40, thereby fixing the reclining position .

In addition, the outside of the seat lower part 31 of the seat body 30 is received The support surface 24 of the receiving platform of the platform 20 is supported so that it can bear the load when the infant is riding. The lower curved guide member 40 and the cylindrical curved surface 25 of the receiving table 20 are arranged to be slightly separated. The above-mentioned outer surface of the seat lower portion 31 slides and is supported on the receiving platform support surface 24 of the receiving platform 20 during the reclining operation and the rotating operation of the seat body 30. In addition, the lower guide member 40 is engaged, and is slightly separated from the cylindrical curved surface 25 of the receiving table 20 during the reclining operation and the rotating operation of the seat body 30. In other words, the size or shape of the outer surface of the seat body 30 is determined such that it can always be in contact with and supported by the support surface 24 of the receiving platform; and the size or shape of the lower guide member 40 is engaged, then It was decided that it would only be slightly separated from the cylindrical curved surface 25.

The seat body 30 abuts on the convex curved surface-shaped protrusion 24a formed on the receiving table support surface 24 of the receiving table 20 in a point-like manner, thereby reducing frictional resistance and sliding smoothly.

In this state, by releasing the engagement between the rotation lock pin 51 and the lock groove 25b (not shown), the seat body 30 can be rotated about the axis of rotation that roughly coincides with the center axis of the reclining lock pin 50 R while rotating motion. In addition, the tilt lock pin 50 and the rotation lock pin 51 are formed of metal such as carbon steel, but it is not limited thereto.

When the seat body 30 is rotated with respect to the receiving table 20, the lower engaged guide member 40 attached to the seat body 30 causes the engaging hook 41a of the lower connecting rod 41 and the annular engaging groove 40a 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 is restricted as described above, it is relative to the receiving table 20 still. Therefore, the engaging hook 41a of the lower connecting rod 41 slides relatively while being engaged in the annular engaging groove 40a of the lower engaged guide member 40.

In addition, when the seat body 30 is rotated with respect to the receiving table 20, the guide member 44 attached to the upper part of the seat body 30 is engaged, and each tip of the upper connecting rod 43 and the cylindrical guide wall 44a always rotates together with the seat body 30 in the engaged state. At this time, the upper connecting rod 43 is relatively stationary with respect to the receiving table 20. Therefore, each front end of the upper connecting rod 43 slides relatively while being engaged along the cylindrical guide wall 44a of the upper guide member 44 to be engaged.

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

FIG. 13 shows a state in which the seat body 30 is tilted relative to the receiving table 20 from the rear down position shown in FIG. 12 to the front down position. That is, from the state shown in FIG. 12, the engagement between the tilt lock pin 50 and the rear lock hole 25a is released, and the seat body 30 slides forward along the receiving table support surface 24. Next, the reclining locking pin 50 is engaged with the front locking hole 25a, thereby fixing the reclining position.

The lower connecting rod 41 and the upper connecting rod 43 connecting the engaged guide member 40 of the lower part of the seat body 30 and the upper engaged guide member 44 will follow the reclining action of the seat body 30 and move along Guide groove of receiving platform 20 22b slides forward and backward. Therefore, the seat body 30 performs the tilting operation and the rotation operation of the receiving table 20, but the lower connecting rod 41 and the upper connecting rod 43 connected through the rod connecting member 42 are caught on the lower part of the seat body 30 The engagement guide member 40 and the upper engagement guide member 44 maintain the engaged state all the time, that is, they are connected while maintaining the relative positional relationship with the seat body 30.

In addition, of course, the seat body 30 may be set to the reclining position corresponding to the central locking hole 25a. When the seat body 30 is located in the down position corresponding to the central locking hole 25a and in the down position corresponding to the front locking hole 25a, the seat body 30 may also be placed around the down locking pin The central axis of 50, that is, the rotational movement about the rotation axis R.

In addition, 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. In addition, in the figures of FIGS. 14 and 15, the upper figure is a cross-sectional view in the line XX including the figure below and schematically shows the viewpoint from above, while the figure below is the line containing the figure above YY, that is along The cross-sectional view of the line of the locking groove 25b on the left side schematically shows the viewpoint from the side.

The reclining operation will be described. FIG. 14 (a) shows the forward state of the seat body 30, and the reclining operation lever 55a and the rotation operation lever 55b are not operated. The tilting locking pin 50 is engaged with the central locking hole 25a among the three locking holes 25a, and the rotating locking pin 51 is engaged with the locking groove 25b on the left side. FIG. 14 (b) shows the state in which the tilting operation lever 55a is pulled forward, and shows that the tilting locking pin 50 has moved upward and the engagement with the locking hole 25a has been released.

FIG. 14 (c) shows a state where the reclining operation lever 55a is pulled forward, and the seat body 30 is slid forward. That is, this operation is a reclining operation that causes the seat body 30 to recline the receiving table 20. During the tilting operation, the rotation lock pin 51 is engaged with the lock groove 25b. FIG. 14 (d) is an operation of fixing the seat body 30 to the receiving table 20 after the seat body 30 has been slid forward, that is, after being reclined. That is, the tilt operation lever 55a is released, whereby the tilt operation lever 55a returns to the rear position, and the tilt lock pin 50 is inserted into the front lock hole 25a to engage.

15 (a) shows the forward state of the seat body 30 and the state in which the reclining operation lever 55a and the rotation operation lever 55b are not operated. The tilt lock pin 50 is engaged with the center lock hole 25a of the three lock holes 25a aligned in the front-back direction, and the rotation lock pin 51 is engaged with the left lock groove 25b. 15 (b) shows the state in which the rotation operation lever 55b has been pulled forward, showing that the rotation lock pin 51 has moved upward and has been released The state of engagement with the locking groove 25b is recognized.

15 (c) shows the state where the reclining operation lever 55a has been pulled forward, and the seat body 30 is rotated 180 degrees about the rotation axis R of the reclining lock pin 50. That is, this operation is a rotation operation of rotating the seat body 30 with respect to the receiving table 20 and changing the seat body 30 from the forward state to the backward state. During the rotation operation, the locking pin 50 will be engaged with the locking hole 25a. FIG. 15 (d) is an operation of fixing the seat body 30 to the receiving table 20 after the seat body 30 has been rotated. That is, when the rotary operation lever 55b is released, the rotary operation lever 55b returns to the rear position, and the rotary locking pin 51 is inserted into the other locking groove 25b to engage.

The reclining mechanism and the rotating mechanism of the child seat 1 are as follows: The child seat 1 is provided with: a receiving table 20 having a lower connecting rod 41 and an upper connecting rod 43 as an engaging portion, and a lower engaging guide member 40 and the upper engaged guide member 44 as the seat body 30 of the engaged portion engaged with the engaging portion, will be maintained when the reclining position of the seat body 30 is changed and the seat body 30 is rotated The engagement between the engaging portion and the engaged portion. That is, the relative positional relationship of these components is always constant. Therefore, the child seat 1 can use a simple mechanism with a small number of parts and a miniaturized part compared to the conventional child seat with a reclining mechanism and a rotation mechanism, regardless of the rotation position of the seat body 30 relative to the receiving table 20 The seat body can be tilted.

In addition, in the child seat 1, since the reclining mechanism and the rotating mechanism are arranged at the lower part, that is, at the lower part of the seat 31 and the rising part 22 of the receiving table 20, the seat body 30 is reclined During the operation and the rotation operation, the seat body 30 is stably supported relative to the receiving table 20, resulting in As a result, it is possible to operate stably. In addition, since the reclining mechanism and the rotating mechanism are arranged at the lower portion of the rising portion 22 of the receiving table 20, the upper portion of the rising portion 22 of the receiving table 20 can be used freely.

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

In addition, since the reclining lock pin 50 and the rotation lock pin 51 of the child seat 1 are formed separately and can be operated independently, compared to, for example, the child seat described in Patent Document 1, it is a single lock The protruding amount of the pin is used to select the tipping action and the rotation action, and a simple mechanism can be used to perform a reliable and stable operation. In addition, since there is no need to change the protrusion amount according to the required operation, the processing accuracy or assembly accuracy of each part of the reclining mechanism and the rotating mechanism is less strict than the child seat described in Patent Document 1. As a result, Can reduce the cost of parts or manufacturing costs.

In addition, between the reclining operation and the rotating operation, as long as the engagement between the receiving table 20 and the seat body 30 can be maintained, the engaging portion and the engaged portion can be arbitrarily configured. For example, the receiving table 20 may have only one of the lower engaged guide member 40 and the upper engaged guide member 44, and the seat body 30 may have the corresponding lower connecting rod 41 and upper connecting rod. One of 43. The lower guide member 40 to be engaged may not be disc-shaped, but may be ring-shaped or polygonal. The lower engaged guide member 40 and the upper engaged guide member 44 may be formed integrally with the seat body 30.

As a connecting member between the lower engaged guide member 40 and the upper engaged guide member 44, the lower connecting rod 41 and the rod connecting member 42 and the upper The part connecting rod 43 may be formed integrally. In addition, the lower connecting rod 41 and the rod connecting member 42 and the upper connecting rod 43 are behind the seat body 30 in the child seat 1, that is, on the side of the rising portion 22 of the receiving table 20, and are engaged with the lower part The guide member 40 and the upper portion are engaged by the engaging guide member 44, but as long as they can move back and forth in response to the reclining action of the seat body 30, other arrangements may be used.

In the cylindrical curved surface 25 of the receiving table 20, three locking holes 25a are formed, but it may be two or more than four. That is, the position of the reclining corresponding to the number of the locking holes 25a may be set to any number, and these may not be equally spaced. In addition, a pair of locking grooves 25b are formed parallel to the center line H on the cylindrical curved surface 25 of the receiving table 20, but the center line H may be formed with an arbitrary angle, for example, a perpendicular locking groove. That is, in addition to the forward state and the backward state of the seat body 30, the infant may be oriented in the lateral direction and facing the side. In this side-facing state, it is also possible to provide a plurality of locking holes in the lateral direction to make the reclining action possible.

However, as described above, the child seat 1 can tilt the seat body 30 by pulling the tilt operation lever 55a, and can rotate the seat body 30 by pulling the rotation operation lever 55b. If these reclining motions and rotation motions can be performed at the same time, the seat body 30 will produce complex and unpredictable trajectories, which may hit the operator. Therefore, the child seat 1 is configured so that the reclining motion and the turning motion cannot be performed at the same time.

Referring to FIGS. 16 to 18, the operation mechanism for tilting the operating lever 55 a and rotating the operating lever 55 b will be described. 16 is a diagram illustrating the operation mechanism of the child seat 1, and FIG. 17 is another diagram illustrating the operation mechanism of the child seat 1. 18 is a diagram illustrating another 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-shaped member formed into a shape with curved sides, such as a crescent shape or a bar shape. The operation switch 57 is rotatably attached to the operating table 55 around the fixing pin 57a by a fixing pin 57a in the central portion thereof. On the curved outer side of the both end portions of the operation switch 57, that is, the side surface on the rear side, an abutment surface 57 b is formed that extends toward the front of the seat body 30 and extends outward. In addition, since the operation switch 57 is covered from above by the tilt operation lever 55a and the rotation operation lever 55b, it cannot be recognized from the outside.

The operation lever 56a is connected to the tilting operation lever 55a by the lever holding member 58a, and the operation lever 56b is connected to the rotation operation lever 55b by the lever holding member 58b. That is, the end of the operating lever 56a is bent upward, that is, in the figure, it is bent vertically to the direction of the reader, and the corresponding L-shaped lever holding member 58a is fitted from above That is, in the figure, the paper is vertically fitted from the direction of the reader, thereby connecting. The same is true for the lever holding member 58b. In addition, the lever holding member 58a and the lever holding member 58b may be formed integrally with the reclining 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, downward in the figure, the lever holding member 58a moves forward together with the operation lever 56a. At this time, the front end of the lever holding member 58a, that is, the front end portion, first comes into contact with the abutment surface 57b of the operation switch 57 to make the operation switch 57 go around the fixing pin 57a rotation. If the tilting operation lever 55a is pulled further, as shown in FIG. 17, the tilting operation lever 55a comes into contact with the stopper 55c of the operation table 55 and stops.

In this state, the contact surface 57b of the rotating operation switch 57 will abut the side surface of the lever holding member 58a, and the front end of the other lever holding member 58b, that is, the front end portion, will meet the operation switch 57. The contact surface 57b of the other side abuts. Therefore, the movement of the rotary operation lever 55b is prevented by the contact of the front end of the lever holding member 58b with the contact surface 57b of the operation switch 57. In other words, the shape of the crescent shape or the bar shape of the operation switch 57 is determined such that the other lever holds while the contact surface 57b of the rotating operation switch 57 has contacted the side surface of the lever holding member 58a The front end portion of the member 58b is in contact with the other contact surface 57b of the operation switch 57.

In the state where the tilt operation lever 55a has been pulled (FIG. 17), the rotation operation lever 55b cannot be pulled, and conversely, in the state where the rotation operation lever 55b has been pulled (FIG. 18), the tilt operation lever 55a cannot be pulled. If one of the reclining operation lever 55a or the rotation operation lever 55b that is pulled forward is returned to the original position, the reclining operation lever 55a or the rotation operation lever 55b can be pulled forward. Therefore, according to such an operating mechanism, it is possible to use a simple mechanism to prevent the tilting mechanism and the rotating mechanism from operating at the same time, that is, it is possible to safely implement the alternative operation.

In addition, since the operation of the child seat 1 for tilting and rotating the seat body 30 can be performed only by pulling the tilting operating lever 55a or the rotating operating lever 55b, it can also be operated with only one hand. Use the other hand freely. Furthermore, even if the operating mechanism is operated with one hand, it can be operated stably.

In addition, it may be possible to pull one of the tilt operation lever 55a or the rotation operation lever 55b without sliding the lever holding member 58a until the operation switch 57 comes into contact with the side of the lever holding member 58a even as described above It is also possible to restrict the sliding of the other of the operation lever 55a or the rotation operation lever 55b when the operation switch 57 has been rotated at the front end of the lever holding member 58a. That is, the operation switch 57 may be a rectangular member or the like. In addition, the operation mechanism having the above-mentioned operation switch 57 can be applied not only to the field of child seats, but also to other fields that need to exist to safely implement the alternative operation.

3, in particular, as described above, a rectangular opening 26 is formed in the upper portion of the standing portion 22 of the receiving table 20. That is, in the child seat 1, by placing the reclining mechanism and the rotation mechanism at the lower portion of the seat lower portion 31 and the rising portion 22 of the receiving platform 20, the upper portion of the rising portion 22 of the receiving platform 20 ， Formation opening 26. And the opening 26 can be used as a handle when carrying the child seat 1.

In addition, in the opening 26, as shown in FIG. 4, a mechanism or device 90 having various functions can be mounted. Thereby, the receiving table 20 may have functions other than the supporting function of the seat body 30. In particular, in a state where the seat body 30 is facing backward, for example, a camera can be mounted to take a still picture or a dynamic picture, and a parent or the like can observe the appearance of the infant in a ride through a mobile phone or a car navigation system. In addition, it can also be equipped with a screen so that infants and children can enjoy the video. In addition, it can also be equipped with speakers to let infants and children enjoy the sound. In addition, an electric fan, an air conditioner, a lighting device, etc. may be mounted. In addition, it can also be equipped with a plasma discharge, etc. to release ions into the air Ion generating device. According to such an ion generating device, air purification effects such as air disinfection, dust removal, sterilization, organic matter decomposition, and deodorization, or hair care and skin care effects for hair or skin care of infants or parents can be expected . In addition, in order to make it easy to replace these devices and the like, these devices and the like may be mounted through the mounting member.

In order to use the electric appliance mounted in the opening 26, the battery may be arranged inside the receiving table 20 so as to replace the battery, or a cigarette lighter socket of the vehicle may be used as a power source. The power cord from the battery or cigarette lighter socket to the electrical appliance should be wired such that it does not interfere with the reclining and rotating movements of the seat body 30 through the underside and back of the child seat 1, or is routed through the receiving table 20 inside.

In addition, of course, the opening 26 may have a shape other than a rectangle, for example, a circle. In addition, the opening 26 may penetrate rearward, or it may be only a concave portion. In addition, as described above, the opening 26 can be applied not only to the child seat where the seat body performs the reclining motion and the rotating action on the receiving platform, but also to the type where the seat body is fixed to the receiving platform, or The seat body is attached to the receiving platform.

However, for the purpose of protecting infants and young children under the impact of the vehicle during impact, the child seat must pursue higher impact resistance. The impact resistance can be tested by: the displacement of the child seat relative to the vehicle seat after the impact, or the movement displacement of the irregular child seat caused by the reaction caused by the displacement after the impact, etc. . In order to achieve higher impact performance, it is desired that the child seat can be firmly fixed to the seat of the vehicle. In the fixing of child seats, usually, the safety of vehicle seats is used Safety belt with device. A seat belt device provided in a vehicle seat includes a seat belt, a tongue with a tongue plate into which a seat belt is inserted, and a buckle that can attach and detach the tongue plate.

In this regard, referring to FIG. 4, the child seat 1 has the engaging protrusion 27 formed at the rear of the base 21 of the receiving table 20 on the left and right as described above. The belt engaging protrusion 27 is arranged at a position where it can be engaged with the tongue or the buckle 91 of the seat belt device from the rear side when the receiving table 20 is attached to the vehicle seat. In other words, the band-engaging protrusion 27 is formed to a certain length, and can correspond to the position of the tongue or buckle 91 that differs depending on the vehicle model. In addition, the belt engagement protrusion 27 may be a groove-shaped belt engagement groove as long as it can engage with the tongue or buckle 91 of the seat belt device.

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

In addition, the engaging protrusion 27 or the engaging groove should preferably be formed as: the concave portion between the receiving table 20 and the engaging protrusion 27 engaged by the tongue or buckle 91 or perpendicular to the longitudinal direction of the engaging groove The cross-sectional shape of will form an acute angle, so that the buckle tongue or buckle 91 will not deviate or loosen and can be more surely engaged. In addition, the engaging protrusion 27 or the engaging groove may not be an engaging tongue or a buckle 91, but a safety belt for engaging a seat belt device. At this time, by fixing the lower part of the receiving table 20 of the child seat 1, the conventional child seat can be compared Fix more firmly. In addition, the engaging protrusion 27 may be formed separately from the receiving table 20.

As described above, with the engaging protrusions 27 or with engaging grooves, it can be applied not only to a child seat in which the seat body can perform a reclining action and a rotating action on the receiving table, but also to the seat body fixed to the receiving The form of the table or the seat body is detachably mounted on the receiving table.

The child seat 1 has a plurality of support points for impact in order to achieve a higher impact resistance performance in order to suppress the displacement of the seat body 30 to the receiving table 20. That is, for example, when the vehicle hits an object from the front, the child seat 1 as a whole receives an inertial force forward. At this time, the seat body 30 is not fixed by the vehicle seat belt with respect to the receiving table 20 being fixed by the vehicle seat belt. Therefore, the seat body 30 is displaced forward, but the seat body 30 is in contact with the receiving platform 20 at the support point and is supported, whereby the amount of displacement of the seat body 30 can be suppressed.

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

Similarly, the impact support surface 44b formed on the outer peripheral surface of the engaged guide member 44 attached to the upper portion of the seat body 30 and the front end portion of the receiving table 20 The support wall 28a on the side forms a support point B. In addition, a ring-shaped upper surface 40d (FIG. 8) attached to the lower portion of the seat body 30 to be engaged with the guide member 40 and the lower end of the support wall 23a constituting the body storage opening 23 of the receiving table 20 form a support Point C. In FIG. 10, the support point C is a rear end portion of the lower end portion of the support wall 23a of the receiving table 20, and a rear end portion of the upper surface 40d of the lower engaged guide member 40.

The support point C may be 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 engaged guide member 40 because of the reclining position of the seat body 30. That is, the upper surface 40d of the lower engaged guide member 40 can form a support point C with the lower end of the support wall 23a of the receiving table 20 in any down position, and the lower engaged guide member 40 Is formed to be larger than the width L (FIG. 5) of the body storage opening 23 of the receiving table 20 in the lateral direction. Thereby, in the child seat 1, the seat body 30 stored in the body storage opening 23 can be prevented from sliding out of the receiving table 20.

By having support points A, B, and C, the child seat 1 can particularly suppress the displacement of the seat body 30 relative to the receiving platform 20, that is, can suppress the forward movement of the seat body 30 relative to the receiving platform 20 . As a result, higher impact resistance can be achieved. In addition, since the support points A, B, and C are arranged under the seat lower portion 31 of the child seat 1 and the lower portion of the rising portion 22 of the receiving table 20, the receiving table 20 can support the seat body 30 more stably. In addition, the receiving platform 20 supports the seat body 30 with a plurality of support points A, B, and C, whereby the impact can be dispersed, so the materials forming the receiving platform 20 and the seat body 30 can be changed from metal or the like to Lightweight resins can also reduce costs.

In addition, the receiving platform 20 and the seat body 30 do not need to be in constant contact at the support point, but can also be slightly separated, and only come into contact when impacted. In addition, 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, B, and C. In addition, the supporting point for achieving high impact resistance is not limited to the above three parts. That is, the portion of the seat body 30 that is in contact with the receiving table 20 may include the front portion and the rear portion of the upper engaged guide member 44, and further include the lower portion than the front portion and the rear portion. The lower part is arbitrarily configured in the lower part of the engagement guide member 40.

Referring to FIGS. 19 to 22, the height adjustment mechanism of the infant carrier 70 (FIG. 1) will be described. 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 of the child seat, and FIG. 21 is a view illustrating the height adjustment mechanism of the child seat belt 70 of the child seat 1. FIG. 22 is another view explaining the height adjustment mechanism of the infant carrier of the child seat 1. FIG. In addition, in FIG. 19, the back plate 68 described later is omitted.

In order to restrict infants and young children to the child seat 1 safely, the child seat 1 has a child care belt 70 corresponding to the width of the seat belt provided in the vehicle seat. The infant belts 70 are respectively arranged on the left and right of the front of the backrest portion 32 of the seat body 30, and the infant belts 70 on the left and right are fastened on the front of the torso of the infant. Therefore, the infant carrier 70 extends from the rear of the backrest portion 32 of the seat body 30, extends forward through the backrest portion 32, and extends downward through the seat surface 31, that is, the seat lower portion 31, at the seat lower portion The part below 31 is fixed.

From the seating surface of the seat body 30 to the position of the portion of the backrest portion 32 through which the infant carrier 70 passes, that is, the height of the infant carrier 70, the height of the infant carrier 70 must be adjusted according to the height of the infant. Therefore, the child seat 1 has a height adjustment mechanism for the infant carrier 70 in order to appropriately adjust the height of the infant carrier 70.

Therefore, two openings 36 extending in the vertical direction, that is, in the height direction are formed on the backing portion 32 of the seat body 30. These openings 36 are formed to be bilaterally symmetrical with the support portion 37 in the center of the backing portion 32 interposed therebetween, and are formed in the height direction to a range required as the height of the infant carrier 70. Through these openings 36, a moving portion 61 is mounted so as to be slidable in the height direction relative to the backing portion 32, and the moving portion 61 includes the above-mentioned head plate 60 disposed in front of the backing portion 32.

The moving portion 61 includes a head plate 60 disposed in front of the backing portion 32, a rotation support member 62 disposed on the back of the backing portion 32, and attached to the head plate 60 through the two openings 36 of the backing portion 32. The first engagement member 63 attached to the support member 62 and the second engagement member 64 attached to the first engagement member 63. In addition, in FIG. 20, the rotation support member 62, the first engagement member 63, and the second engagement member 64 are drawn slightly enlarged relative to the backing portion 32 and the head plate 60 to make it clear. In addition, since the head plate 60 holds the infant carrier 70 through the slot opening 60a, the head plate 60 constitutes a belt holding member, but it may be configured to be held by other members.

In the head board 60, two slot openings 60a having substantially the same width as the opening 36 are formed at positions corresponding to the two openings 36 of the backing portion 32 in order to insert the baby carrier 70, respectively. Above each slot opening 60a and in the center of the head plate 60, an opening 36 penetrating through the backing portion 32 is formed to protrude rearward The mounting part 60b. Below each slot opening 60a and in the center of the head plate 60, a beam-shaped engaged beam 60c that protrudes rearward through the opening 36 of the backing portion 32 is formed. At the tip of each engaged beam 60c, an engagement hole 60d penetrating in the vertical direction is formed.

On the left side of the left slot opening 60a and the right side of the right slot opening 60a, there is formed a flat support plate 60e that protrudes rearward through the opening 36 of the backing portion 32 and expands in the height direction. The support plate 60e is formed with a concave portion 60f for accommodating a cylindrical engagement rod 65 described later. In addition, below each groove opening 60a, two vent openings 60g that are always open toward each opening 36 regardless of the height position of the head plate 60 are formed.

The rotation support member 62 includes a cover 62a, a rectangular flat protective wall 62b protruding upward from the cover 62a, and a flat first knob 62c protruding rearward from the cover 62a. For the mounting portion 60b (FIG. 19) of the head plate 60 protruding through the openings 36 of the backing portion 32, the cover 62 a is mounted, whereby the head plate 60 and the rotation support member 62 can be integrally mounted. At this time, between the head plate 60 and the rotation support member 62, the pillar portion 37 of the abutment portion 32 is arranged. The protective wall 62b can prevent the operator's hand from hitting the pillar portion 37 of the seat body 30 when the moving portion 61 is operated.

The first engagement member 63 has a box-shaped body member 63a. On the back surface of the body member 63a, a rectangular opening 63b is formed. The upper portion of the main body member 63a is to rotatably mount the first engagement member 63 about a rotation axis extending in the lateral direction, and to attach the housing 62a of the rotation support member 62. In addition, at the lower part of the main body member 63a, cylindrical engaging rods 65 extend toward the left and right outer sides, respectively. The engaging rod 65 has a horizontal direction inserted inside The reinforcing rod 65a is used for reinforcement. The reinforcing bar 65a is formed of metal such as carbon steel, but it is not limited thereto.

On the back surface of the backing portion 32, the engaged curved surface portion 38 is formed on the left side of the pillar portion 37, the left side opening 36, and the right side of the right opening 36. The engaged curved surface portion 38 has a configuration including a part of a cylindrical surface extending in the horizontal direction and a concave curved surface in which the entrance is formed to be wide for easy storage of the cylindrical engaging rod 65 and is aligned in the horizontal direction A plurality of them are arranged at equal intervals in the height direction.

By engaging the engaging rod 65 of the first engaging member 63 with the concave curved surface of any one of the curved surfaces 38 to be engaged, the arbitrary height position of the head plate 60 relative to the backing portion 32 can be adjusted. At this time, the engagement bar 65 of the first engagement member 63 that has engaged with the engaged curved surface portion 38 will also be accommodated in the support plate of the head plate 60 that slides in the height direction together with the first engagement member 63 In the recess 60f of 60e. In addition, the first engagement member 63 is integrally formed with left and right torsion springs 63c inside the rotation support member 62, and is provided to engage the engagement rod 65 with the engaged curved surface portion 38 of the backing portion 32 Potential energy in the direction of rotation.

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

21, the operation of adjusting the height of the infant carrier 70 will be described. 21 is a diagram illustrating the height adjustment mechanism of the infant carrier 70 of the child seat 1 as described above, and is a schematic longitudinal cross-sectional view passing through the center of the seat body 30, that is, the width direction of the moving portion 61. First, simultaneously hold the first handle 62c of the rotation support member 62 and the second handle 64b of the second engagement member 64, and pull the second handle 64b upward toward the direction of the first handle 62c (FIG. 21 (a)) ). That is, the second engagement member 64 is pulled upward relative to the first engagement member 63. This operation is performed, for example, by placing the thumb on the upper surface of the first handle 62c, touching the index finger and middle finger to the lower surface of the second handle 64b, and pulling upward. By pulling the second engagement member 64 upward relative to the first engagement member 63, the engagement of the engagement pin 66 of the second engagement member 64 and the engaged beam 60c of the head plate 60 can be released The engagement between the holes 60d. As a result, the first engagement member 63 becomes rotatable with respect to the rotation support member 62 (FIG. 21 (b)).

In addition, if the operation of pulling up the second handle 64 b of the second engagement member 64 is continued, the first engagement member 63 will rotate relative to the rotation support member 62. Thereby, the engagement between the engagement rod 65 of the first engagement member 63 and the engaged curved surface portion 38 on the back of the backing portion 32 can be released. As a result, the head plate 60 can be slid in the height direction relative to the backing portion 32 (FIG. 21 (c)). In this state, by sliding the head plate 60 through which the infant harness 70 is inserted into the slot opening 60a, relative to the backing portion 32 and sliding in the height direction, the infant harness 70 can be slid to a desired height.

Here, in a state where the second engagement member 64 is pulled upward relative to the first engagement member 63 to release the engagement of the engagement pin 66, if the first engagement member 63 is moved relative to the rotation support member 62, By rotating, the sliding of the second engagement member 64 relative to the first engagement member 63 can be restricted. This will be described with reference to FIG. 22. 22 is another view explaining the infant seat belt height adjustment mechanism of the child seat 1 as described above, and is a longitudinal cross-sectional view of the side surface including 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, on the side surface of the second engagement member 64, an engagement protrusion 64 c (see also FIG. 20) is formed, and inside the housing 62 a of the rotation support member 62, an engagement recess 62 d is formed. From the state of FIG. 22 (a), the second engagement member 64 is pulled upward relative to the first engagement member 63 (FIG. 22 (b)), and then the first engagement member 63 is moved relative to the rotation support member 62. And rotate. As a result, the locking protrusion 64c of the second engaging member 64 is engaged with the locking concave portion 62d of the rotation support member 62 (FIG. 22 (c)). As a result, the sliding of the second engagement member 64 relative to the first engagement member 63 is restricted.

Therefore, even in this state, the pull-up force of the second handle 64b of the second engagement member 64 is weakened, and by the force imparted by the coil spring 64a to the potential energy, the engagement pin 66 does not protrude again. In other words, the second engaging member 64 that has slid upward is safely configured as long as it is not in a state where the engaging rod 65 of the first engaging member 63 has engaged with the engaged curved surface portion 38 of the backing portion 32 , The second engaging member 64 will not return to its original position.

After the infant carrier 70 is slid to the desired height, the infant carrier 70 should be fixed at this height, as long as one of the above series of actions is reversed Just go ahead. That is, the first engagement member 63 is rotated relative to the rotation support member 62 to engage the engagement rod 65 of the first engagement member 63 with the engaged curved surface portion 38 of the backing portion 32. Thereby, the engagement between the locking protrusion 64c of the second engaging member 64 and the locking concave portion 62d of the rotation support member 62 can be released. Next, the second engaging member 64 is slid downward relative to the first engaging member 63 to engage the engaging pin 66 of the second engaging member 64 with the engaging hole 60d of the engaged beam 60c of the head plate 60 Together. These actions are all assisted by the torsion spring 63c and the coil spring 64a to the force imparting potential energy, so they can be easily performed.

The height adjustment mechanism of the infant carrier 70 described above has two engagements: the engagement of the second engagement member 64 to the head plate 60 and the engagement of the first engagement member 63 to the backing portion 32, so Even if an impact is applied to the entire child seat 1, the engagement on both sides will not loosen. That is, the second engagement member 64 disengages the head plate 60 by moving upwards, and the first engagement member 63 disengages the backing portion 32 by releasing The movement is performed in the direction of rotation, that is, the direction away from the abutment portion 32. Therefore, the direction of the force required to release these engagements is slightly orthogonal.

In addition, the second engagement member 64 is released from the head plate 60 and the first engagement member 63 is released from the abutment portion 32 by moving the second handle 64b of the second engagement member 64 toward A series of continuous actions of pulling up. That is, by applying a force to the second handle 64b of the second engagement member 64 in the same upward direction all the time, the two-stage engagement can be released. Therefore, the height adjustment mechanism of the above-mentioned infant carrier 70 is configured such that it is difficult to unintentionally release the engagement, but it is easy to consciously release the engagement.

In addition, since the supporting portion 37 is left in the center of the backing portion 32 to form the engaged curved surface portion 38, the strength of the backing portion 32 can be maintained. In addition, since the concave curved surface of the engaged curved surface portion 38 of the backing portion 32 is formed to be aligned in three rows in the height direction, it can be prevented that the engaging rod 65 of the first engaging member 63 is not engaged in one The course is a concave curved surface that is accidentally engaged with the engaged curved surface portion 38 at different heights from each other.

In addition, the height adjustment mechanism of the infant carrier 70, that is, the movement mechanism may be of any configuration as long as it can be operated by the operation described with reference to FIG. 21. That is, as long as the sliding mechanism is parallel to the direction of the force applied to the second engagement member, the engagement is first released by the sliding of the second engagement member, and then by the rotation of the first engagement member To release the engagement and make it slidable, it can be arbitrarily constructed. In addition, the above-mentioned height adjustment mechanism 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 a moving mechanism.

However, after properly adjusting the height of the infant carrier 70 according to the height of the infant and the child by the height adjustment mechanism described above, it is necessary to properly adjust the tightness of the infant carrier 70 according to the body shape of the infant, that is, the backrest portion 32 Length extending forward.

23 and 24, the adjustment of the length of the infant carrier 70 using the adjustment belt 75 will be described. FIG. 23 is a perspective view showing the adjustment belt 75 at the uppermost position of the child seat 1, and FIG. 24 is a perspective view showing the adjustment belt 75 at the lowermost position of the child seat 1. 23 and 24 are perspective views of the seat body 30 of the child seat 1 viewed 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 therefore, are constituted by one belt. In addition, the infant carrier 70 is connected to one end of one wide adjustment belt 75 on the rear side of the back portion 32 of the seat body 30. That is, one end of the adjusting belt 75 is folded in half and overlaps with the part folded back to be sewn. As a result, at one end of the adjustment belt 75, an annular portion 75a is formed. The infant carrier 70 is inserted into the annular portion 75a. Therefore, the loop portion 75a of the adjustment belt 75 constitutes a connection portion with the infant carrier 70. The adjusting belt 75 is formed by weaving materials generally used for vehicle seat belts, such as polyester fiber, but it is not limited thereto.

The adjusting belt 75 extends downward along the backing portion 32 of the seat body 30 from the vicinity of the lower end of the seat body 30, that is, the opening 31c formed in the lower portion of the rear side of the cylindrical portion 31b of the seat lower portion 31 ( 7), enter the internal space 35. Next, referring to FIG. 9, the adjustment belt 75 that enters the inner space 35 of the seat body 30 is a belt support protrusion 33e that protrudes upward by being formed on the bottom surface of the inner space 35, and is bent at an acute angle to face The upper part extends to the vicinity of the lower part of the seat panel 34.

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

The belt adjusting tool 76 can lock and release the adjusting belt 75 by a well-known mechanism. When the adjusting belt 75 is locked by the belt adjuster 76, the adjusting belt 75 cannot be moved forward and backward relative to the belt adjuster 76. On the other hand, when the lock of the belt adjuster 76 is released, the adjustment belt 75 can be moved forward and backward relative to the belt adjuster 76.

Next, the length adjustment of the infant carrier 70 will be described. The length adjustment of the infant carrier 70 is performed in a state where the belt adjuster 76 is unlocked. When the length of the infant carrier 70 extending toward the front of the backrest 32 is desired to be longer, the infant carrier 70 extending toward the front of the backrest 32 can be lengthened by pulling it forward or upward. Finally, the infant carrier 70 can be pulled until there is no extra part behind the back 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 loop portion 75a of the adjustment belt 75 connected to the child care belt 70 is located at the uppermost position (FIG. 23).

The uppermost position of the adjusting belt 75 refers to a position where the annular portion 75a corresponds to the portion formed by the slot opening 60a through which the head board 60 of the infant carrier 70 is inserted. Therefore, the uppermost position of the adjustment belt 75 will vary according to the height adjusted by the height adjustment mechanism of the infant belt 70.

On the other hand, when it is desired to shorten the length of the infant carrier 70 extending toward the front of the backrest portion 32, the portion of the adjustment belt 75 extending toward the front of the seat body 30 (FIG. 1) can be moved forward Pull to make it shorter. Finally, the adjustment belt 75 may be pulled until the end portion 75a of the adjustment belt 75 connected to the infant carrier 70 is disposed near the opening 31c of the seat lower portion 31. At this time, the length of the infant carrier 70 extending toward the front of the back abutment portion 32 is the shortest. The loop portion 75a of the adjustment belt 75 connected to the belt 70 will be at the lowermost position (FIG. 24).

The lowermost position of the adjusting belt 75 refers to the position of the annular portion 75a near the opening 31c of the seat lower portion 31. Therefore, the lowermost position of the adjusting belt 75 is the position fixed to the opening 31c of the seat lower portion 31.

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

In the child seat 1, the adjusting belt 75 extends to the vicinity of the lower end of the rear side of the seat body 30, that is, the opening 31c formed in the lower part of the rear side 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 bent upward at an acute angle due to the belt support protrusion 33e. Therefore, the adjustment belt 75 is directed toward the belt adjuster 76, not through the shortest distance, but around a detour path. Therefore, in the child seat 1, by arranging the lowermost position of the adjusting belt 75 in the vicinity of the lower end of the seat body 30 below the conventional child seat, the uppermost position of the adjusting belt 75 can be ensured And the distance between the lowest position is longer. As a result, the range of adjustment of the length of the infant carrier 70 can be made wider.

In addition, in order to make the adjustment of the adjustment belt 75 smooth, a pulley may be arranged at a portion that is in contact with the seat body 30, for example, above the opening 31c. In addition, the adjustment belt 75 may not be passed through the inside of the seat body 30, but through the outside thereof, that is, through the lower surface of the seat body 30.

A back panel (harness panel) 68 is attached to the back of the seat 32 against the back 32. FIG. 25 is an enlarged view of the back of the child seat 1 Fig. 26 is a perspective view of the back panel 68 of the child seat 1. The back plate 68 can achieve the following effect: the extra child care belt 70 and the adjusting belt 75 arranged behind the back portion 32 of the seat body 30 are covered and stored on the back of the back portion 32 so as not to Will hinder use. In addition, the back panel 68 can cover a part of the moving portion 61 and the engaged curved surface portions 38 formed on both sides of the opening 36 of the back 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 arranged so as to extend in the height direction in the central portion of the seat body 30 in the width direction, and is fitted and installed with the seat body 30. The back panel 68 has an upper panel 68a and a lower panel 68b. The back panel 68 is formed integrally by injection molding from a resin material such as polypropylene with flexibility. In particular, a hinge 68c is formed at the boundary between the upper panel portion 68a and the lower panel portion 68b of the back panel 68. The hinge 68c is formed thinner than other parts and can be bent repeatedly without being damaged. However, the back panel 68 may omit the hinge 68c and bend with its flexibility. In addition, the infant carrier 70 and the adjusting belt 75 are accommodated in a storage 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 backing portion 32 of the seat body 30, but by releasing this engagement, the upper panel 68a can be bent rearward with the hinge 68c as the center, so that the seat body 30 and The storage space 68d between the back panels 68 is open. That is, the back plate 68 can be partially separated from the backing portion 32. For example, when adjusting the excess portion of the baby carrier 70 disposed on the back side of the seat body 30, the upper panel portion 68a of the back panel 68 can be bent and opened to facilitate work.

Also, in the upper portion 68a of the back panel 68, in the width direction In the central portion, an opening 68e is formed in the height direction. The width of the opening 68e is larger than the width of the pillar portion 37 of the backing portion 32 of the seat body 30. Therefore, the two openings 36 of the backing portion 32 are partially exposed through the opening 68e of the back panel 68. 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 ensured to ensure the ventilation so that Infants and young children will not feel uncomfortable. In addition, by forming the opening 68e in the back panel 68, the moving section 61 can be operated with the back panel 68 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.

With reference to FIGS. 27 to 29, the infant carrier 70 will be described. FIG. 27 is a top view of a part of the infant carrier 70, FIG. 28 is a side view of the infant carrier 70 of FIG. 1 in an extended state, and FIG. 29 is a side view of the infant carrier 70 of FIG. 1 in a bent state.

The infant carrier 70 used in the child seat 1 is formed by superimposing a plurality of flexible belts 71 in a belt shape, for example, two belts 71a and 71b. The belts 71a and 71b are formed by weaving materials generally used for vehicle seat belts, for example, polyester fibers. The tapes 71a and 71b are sewn along a plurality of threads extending in the longitudinal direction, for example, two threads 71c.

When the infant carrier 70 is bent, after releasing the bending force, the bending state is maintained against the gravity. That is, when the overlapping strips 71 are bent, the radius of curvature of the strip 71a inside the bend is smaller than the radius of curvature of the strip 71b outside the bend. Because of this radius of curvature The difference is that between the outer surface of the opposite inner tape 71a and the inner surface of the outer tape 71b, it is elongated in the circumferential direction of the bend, for example, the longitudinal direction of the tape 71, causing deviation. Then, when the bending force is released, the stretched outer belt 71b of the infant carrier 70 will return to the original state, but the outer surface of the inner belt 71a and the inner side of the outer belt 71 The surface will be blocked due to frictional resistance. As a result, the deformed infant carrier 70, even after releasing the force to deform it, maintains its shape against gravity.

Therefore, even if the parent releases the infant carrier 70 and takes the infant from the child seat, the infant carrier 70 will maintain the shape against gravity, so that the infant will not be hindered when he rides it. In addition, since the tapes 71a and 71b are formed of a soft material such as polyester fiber, it is safe even if an infant or a parent touches or hits the infant carrier 70.

In addition, when deforming the infant carrier 70, the straps 71a and 71b may be loosely stitched in order to cause a greater deviation between the two straps 71a and 71b. In addition, the infant carrier 70 may maintain the shape by inserting a wire or a metal plate or the like that can maintain the deformed shape not through frictional resistance. In addition, the entire baby carrier 70 may have a shape-maintaining structure as described above, or may be a partial structure. In addition, a cushion cover 77 (FIG. 1) having a cushioning property may be rolled around the portion of the infant cover 70 that is in contact with the infant. In this case, the infant cover 77 may be configured to maintain the shape as described above. In addition, the above-mentioned infant carrier 70 can be applied not only in the field of child seats, but also in need. In other areas of the belt that maintains its shape against gravity.

7 and FIG. 30, a method of attaching the infant carrier 70 to the seat body 30 will be described. 30 is a front view of the infant carrier 70 of the child seat 1. FIG. In particular, the infant carrier 70 shown in FIG. 30 is provided at one end with a fastening portion 78 (FIG. 1) for fastening the left and right infant carrier 70 by a fastening mechanism, and is provided on the infant Infant belt 70 for infants between thighs. In the method of attaching the seat body 30, the left and right child care belts 70 are the same as the child care belt 70 of the thigh belt. The infant carrier 70 extending from the backrest portion 32 of the seat body 30 and the infant carrier 70 of the thigh belt are portions that penetrate the seat lower portion 31 downward and are fixed below the seat body 30 as described above. Therefore, as shown in FIG. 7, as shown in FIG. 7, the seat lower portion 31 has rectangular through holes with left and right and front openings 31 f as attachment portions for penetrating and installing the infant carrier 70.

In addition, the front end of the belt 71 constituting the infant carrier 70 penetrating the seat lower portion 31 of the seat body 30 is folded in half and overlaps with the folded back portion to be stitched. As a result, an annular portion 72 formed in a ring shape is formed at the front end of the infant carrier 70.

Next, a cylindrical fixing rod 73 is inserted into the annular portion 72 of the infant carrier 70 passing through the seat lower portion 31 of the seat body 30. The fixing bar 73 is formed by cutting materials such as carbon steel from a metal such as carbon steel, but it is not limited thereto. The fixing bar 73 is formed to be larger than the attachment opening 31f of the seat lower portion 31 through which the infant carrier 70 passes. That is, the length of the cylindrical fixing rod 73 is greater than the horizontal dimension of the rectangular mounting opening 31f, and the diameter of the fixing rod 73 is greater 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 infant carrier 70, the infant carrier 70 will not be loosened from the seat body 30. The fixing bar 73 inserted into the annular portion 72 of the infant carrier 70 is fixed by snap fit by engaging claws 31g formed near the mounting opening 31f of the seat body 30.

Since the infant carrier 70 is securely fixed by snap-fitting of the fixing rod 73, it does not hang down under the seat body 30 and hinder use. In addition, the fixing rod 73 only needs to be rod-shaped, and does not necessarily have to be cylindrical, that is, circular in cross section. The fixing rod 73 may be configured to have a polygonal cross section such as a quadrangular shape or a hexagonal shape, for example.

By cutting the fixing rod 73 that fixes the infant carrier 70 from the rod-shaped material, the raw material cost and the processing cost can be made very cheap. In addition, since the structure of the fixing rod 73 is simple, the strength is also excellent. In addition, the infant carrier 70 uses the fixing rod 73 to fix the seat body 30, and since the fitting is only performed by snap-fitting, the installation work is also easy.

31 and 32, the cover mechanism 80 will be described. 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 as the head plate 60 slides in the vertical direction. The cover mechanism 80 includes a rotation locking mechanism 81, a cover (not shown) covering the infant's head, and one fixed cover stay 82 and two first movable cover stays 83 and 2 that serve as a skeleton for supporting the cover Movable cover stay 84. The rotation locking mechanism 81 includes a pair of stay support members 85, a pair of first rotation locking members 86, and a pair of second rotation locking members attached to the left and right portions of the curved head plate 60. 87.

Both ends of the fixed cover stay 82 are fixedly attached to the left and right stay support members 85. Both ends of the first movable cover stay 83 are carried out stepwise by the first rotation locking member 86 with respect to the left and right stay support members 85, that is, they can be engaged at stepwise rotation positions installation. On the other hand, both end portions of the second movable cover stay 84 are attached to the left and right stay support members 85 through the second rotation locking member 87 to be rotatably mounted in stages.

Therefore, the first movable cover stay 83 and the second movable cover stay 84 can be rotated stepwise toward the front or rear around the rotation axis extending in the lateral direction as a whole. Therefore, the cover can be unfolded forward or folded back. In addition, the first movable hood stay 83 has a larger rotation angle than the second movable hood stay 84, and therefore, it can be deployed further forward than the second movable hood stay 84.

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

On the outer surface of the elastic beam 85b of the stay support member 85, the first rotating end 86a of the first rotation locking member 86 is disposed, and on the inner surface of the elastic beam 85b of the stay support member 85, the first 2 Rotating locking member The second rotating end 87a of 87. The elastic beam 85b, the first rotating end 86a, and the second rotating end 87a are rotatably fastened by inserting a rotating pin 88 in each center.

On a circumference concentric with the rotation center of the first rotation end 86 a of the first rotation locking member 86, two locking concave portions 86 b in the form of concave curved surfaces are formed. Similarly, on a circumference concentric with the rotation center of the second rotation end portion 87a of the second rotation locking member 87, two locking concave portions (not shown) in the shape of a concave curved surface are formed. In addition, on the outer side surface of the rotation support portion 85a of the opposing stay support member 85, on a circumference concentric with the rotation center of the first rotation locking member 86, and with rotation throughout the first rotation locking member 86 At a position corresponding to the locking concave portion 86b of the range, a plurality of locking convex portions 85c (not shown) in a convex curved shape locked with the locking concave portion 86b are formed. Similarly, on the inner side surface of the rotation support portion 85a of the opposing stay support member 85, on a circle concentric with the rotation center of the second rotation locking member 87, and with the entire second rotation locking member 87 At a position corresponding to the locking concave portion 87b of the rotation range, a plurality of locking convex portions 85c in the shape of a convex curved surface locked with the locking concave portion 87b are formed.

In order to unfold or fold the cover, when the first movable cover stay 83 is slightly rotated relative to the stay support member 85, the locking recess 86b of the first rotation lock member 86 and the stay support member are temporarily released The locking between the locking protrusions 85c of 85. That is, the locking convex portion 85c of the stay support member 85 is disposed between the adjacent locking recesses 86b of the first rotation locking member 86, and the rotation support portion 85a of the stay support member 85 and the first The first rotation end 86a of the rotation locking member 86 is slightly separated. In this state Next, by the elastic force of the elastic beam 85b of the stay support member 85 connected to the first rotation end 86a of the first rotation locking member 86, the rotation support portion 85a of the stay support member 85 and the first rotation card The first rotating end 86a of the stop member 86 provides potential energy in a direction approaching each other.

Next, if the first movable cover stay 83 is further rotated with respect to the stay support member 85, the locking recess 86b of the first rotation locking member 86 will be adjacent to the stay support member 85 in the rotation direction The locking convex portion 85c is locked and stabilized. The force imparting potential energy by the elastic beam 85b of the stay support member 85 also contributes to this stable locking. On the other hand, the state in which the locking between the locking concave portion 86b of the first rotation locking member 86 and the locking convex portion 85c of the stay support member 85 is released is an unstable state. Therefore, during the rotation operation of the first movable cover stay 83, the first rotation locking member 86 rotates in stages, that is, it can be locked at the stage of rotation, so that the locking recess 86b and the rotation direction The locking convex portion 85c of the brace support member 85 adjacent to the upper side is locked to be in a stable state.

The rotation of the second movable cover stay 84 with respect to the stay support member 85 is the same as the rotation of the first movable cover stay 83 with respect to the stay support member 85 described above. Therefore, during the rotation operation of the second movable cover stay 84, the second rotation locking member 87 can be rotated in stages so that the locking concave portion is locked to the stay supporting member 85 adjacent to the rotation direction The convex portion 85c is locked and stabilized.

Since the cover mechanism 80 described above can slide up and down together with the head plate 60, the height can be adjusted by a simple operation according to the height of the seated infant. Moreover, since the first rotation locking member 86 The locking concave portion 86b and the locking concave portion of the second rotation locking member 87 are formed into a concave curved surface, and the locking convex portion 85c of the stay supporting member 85 locked with these is formed into a convex curved surface, Therefore, the locking and releasing can be performed very smoothly. Therefore, it is possible to realize a rotation locking mechanism that can be smoothly rotated and locked without requiring lubricating oil even if it is a simple mechanism configured with a small number of parts.

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

33 to 35, the positioning mechanism 110 of the support foot 100 will be described. 33 is a perspective view of the positioning mechanism 110 of the support foot 100 of the child seat 1, FIG. 34 is a longitudinal cross-sectional view of the center of the positioning mechanism 110 of FIG. 33 to the left, and FIG. 35 is a longitudinal view through the center of the positioning mechanism 110 of FIG. Sectional view. In addition, in FIG. 33, in order to clarify the internal structure of the positioning mechanism 110, some of the members are only outlined.

As shown in FIGS. 2 and 3, the support foot 100 extends to the bottom surface of the vehicle that supports 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 Front part. The support foot 100 has a foot 101 that can freely extend and contract in the longitudinal direction, and mounting The positioning mechanism 110 is located on the leg 101 and determines the length of the leg 101.

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

The positioning mechanism 110 is attached to the lower portion of the first cylindrical member 102 and includes a housing 113 including a first housing half 111 and a second housing half 112, a slider 114, and a foot operation lever 115. The first housing half 111 is attached from the front of the first cylindrical member 102, and the second housing half 112 is attached from the rear of the first cylindrical member 102. That is, the first casing half 111 and the second casing half 112 are fitted by sandwiching the first cylindrical member 102 from the front and back, and are attached to the first cylindrical member 102.

In the case 113 on the side of the first case half 111, in the direction perpendicular to the longitudinal direction of the leg 101, that is, between the direction away from the leg 101 passing through the case 113 and the approaching direction, The slider 114 is slidably arranged. That is, in the housing 113 on the side of the first housing half 111, a plurality of guide walls 111a for guiding the slider 114 to slide are formed. A hollow hub 111c protruding rearward is formed on the inner wall 111b of the front face of the first housing half 111, and a coil spring 116 is arranged around the hub 111c.

On the upper part of the slider 114, there is formed a housing half body of the first housing The hub 111c of 111 and the recess 114a of the coil spring 116. Moreover, in the recess 114a of the slider 114, a columnar guide protrusion 114b protruding forward is formed (FIG. 35). That is, the slider 114 accommodates the hub 111c of the first housing half 111 and the coil spring 116 in the recess 114a at the upper portion thereof, and the guide protrusion 114b of the slider 114 is inserted into the hollow hub 111c. Also, protrusions 114c are formed on the left and right of the upper part of the slider 114 (FIG. 34). In addition, at a lower portion of the slider 114, a fixing member 117 (FIG. 35) formed separately from the fixing member 117 protruding rearward is attached. The fixing member 117 may be formed integrally with the slider 114.

At one end of the foot operating lever 115, an operating piece 115a is formed as an operating portion arranged outside the housing, and at the other end of the foot operating lever 115, it is formed inside the housing 113 and A pair of connecting portions 115b to which the right and left protrusions 114c of the slider 114 are connected. In each connecting portion 115b, a long hole 115c is formed, and the protrusion 114c of the corresponding slider 114 is disposed therein. Cylindrical rotation support protrusions 115d are formed on the left and right of the middle part of the foot operation lever 115, respectively. The foot operation lever 115 is installed in the housing 113 by the left and right rotation support protrusions 115d, whereby it can be rotated around the rotation axis extending in the lateral direction.

In a state where the positioning mechanism 110 has been attached to the foot 101, the slider 114 is given potential energy by the coil spring 116 in the direction of the foot 101. Therefore, the fixing member 117 is inserted into any one of the through-holes 102a of the first cylindrical member 102 and the second cylindrical member 103, and the second cylindrical member 103 slides against the first cylindrical member 102. Is limited. In addition, the first cylindrical member 102, the second cylindrical member 103, and the fixing member 117 are formed of metal such as carbon steel, but it is not limited thereto.

When adjusting the length of the foot 101, first, the operating piece 115a of the foot operating lever 115 is pulled upward, that is, in the upward direction, thereby rotating it around the rotation axis of the rotation support protrusion 115d. This operation is performed, for example, by holding the first cylindrical member 102 above the positioning mechanism 110 with the right hand extended from above to below, and using the thumb of the right hand to hook the operation piece 115a from below Lift up. In addition, when the operation piece 115a of the foot operation lever 115 continues to rotate, the operation piece 115a moves toward the foot 101 by the rotation movement.

With the rotational movement of the operation piece 115a like this, the connecting portion 115b at the other end of the foot operating lever 115 will rotate in a direction away from the foot 101. Due to the rotational movement of the connecting portion 115b, the slider 114 slides along the guide wall 111a in a direction away from the leg portion 101. That is, the connecting portion 115b of the foot operating lever 115 performs a rotational movement, and the movement of the slider 114 is restricted in the sliding direction by the guide wall 111a. However, the protrusions 114c on the left and right of the slider 114 move in the long holes 115c according to the rotation positions of the corresponding coupling parts 115b, whereby the rotation of the coupling part 115b is not hindered and the rotation of the coupling part 115b The movement is transformed into a sliding movement of the slider 114. In other words, the shape of the long hole 115c of the connecting portion 115b is determined so that the transformation of the motion can be smoothly performed.

The sliding member 114 slides in a direction away from the foot 101, and the fixing member 117 integrally installed with the sliding member 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, and the length of the foot 101 can be adjusted. At this time, although the right hand is holding the first cylindrical structure Piece 102, but the left hand can be used freely.

Next, for example, using the left hand, the second cylindrical member 103 is slid against the first cylindrical member 102, thereby adjusting the leg portion 101 to a desired length, and making the through hole 102a of the first cylindrical member 102 and Any one of the through holes 103a of the second cylindrical member 103 is aligned. In this state, when the force applied to the operating piece 115a of the foot operating lever 115 is released, the slider 114 will slide in the direction of the foot 101 by the potential imparting force of the coil spring 116. As a result, the fixing member 117 of the foot operation 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 operation lever 115 returns to original position. That is, it can be said that the slider 114 can slide between a fixed position where the leg 101 is fixed and retracted and a release position where the fixation is released.

The positioning mechanism 110 supporting the foot 100 is summarized as follows: when the foot operating lever 115 is rotated in the direction in which the operating piece 115a approaches the foot 101, the connecting portion 115b will move away from the foot 101 and slide the slider 114 To the release position. On the other hand, when the foot operating lever 115 is rotated in the direction in which the operating piece 115a is separated from the foot 101, the connecting portion 115b moves toward the foot 101 to slide the slider 114 to a fixed position.

Since the positioning mechanism 110 described above can hold one side of the foot 101 and slide to the release position of the slider 114 with one hand, the other hand can be used freely, so the foot can be held on one side On the other side of 101, the length of the foot 101 is adjusted with a simple operation on one side. In addition, in order to adjust the length of the foot 101, the operating piece 115a of the foot operating lever 115 must first be operated upward, so even if Even if the infant steps on the operation piece 115a of the foot operation lever 115 from above, the slider 114 is not inadvertently positioned at the release position.

In addition, the material of the main parts has been appropriately mentioned, but the material of the parts not mentioned is mainly formed by integrally molding resin materials such as polypropylene or polyacetal. However, other materials or manufacturing methods can also be used.

The present invention has been described in detail based on specific embodiments. However, if one is familiar with this technical field, various changes and modifications can be made without departing from the scope and ideas of the patent application of the present invention.
