Description

Child seat and child seat fixing unit

Technical Field

The utility model relates to a children's seat (child seat) and children's seat are with fixed unit.

Background

As disclosed in patent document 1(JP2017-132321a), for example, a child seat arranged on a seat of a vehicle is widely used. The child seat disclosed in patent document 1 includes a child seat main body and a fixing unit for fixing the child seat main body to a seat of a vehicle. The fixing unit has a coupler that is detachable from a fixer (anchor) provided on the vehicle. The link projects rearward from the child seat body and has a release operation member for releasing the link with the anchor.

The coupling is miniaturized and the operation amount of the releasing operation member is very small. Therefore, it is also conceivable that the state of the coupling cannot be accurately grasped by operating the release operation member. In other words, it is assumed that it is difficult to know whether or not the coupling between the coupling member and the anchor is released after completion of the predetermined operation of the release operation member.

In order to eliminate such a problem, it is conceivable to design the operation amount of the release operation member to be large, but there is a desire in the industry to continue to use the coupling with a certain use result, instead of redesigning the coupling every time. In particular, in combination with a standardized ISOFIX type fastener, a coupler having many years of use is widely used, and it is advantageous to use the coupler in common from various viewpoints of reliability, safety, cost reduction, and the like.

Detailed Description

An embodiment of the present invention will be described below with reference to a specific example shown in the drawings.

Fig. 1 to 14 are diagrams for explaining an embodiment of the present invention. Fig. 1 shows an overall structure of a specific example of a child car seat (car child seat) 10. As shown in fig. 1, the child seat 10 has a child seat main body 11 and a fixing unit 50 held to the child seat main body 11. The child seat body 11 is used by being mounted on a seat S of a vehicle, typically a seat S of an automobile. The fixing unit 50 is coupled to a anchor a provided in a seat S of a vehicle to fix the child seat body 11 to the seat S. As an example, the child seat main body 11 holds a pair of fixing units 50 arranged to be separated in the width direction. The fixing unit 50 protrudes rearward from the child seat main body 11. Typically, the fastener a provided on the seat of the vehicle may be a fastener conforming to the ISOFIX standard. The fixing unit 50 will be described in detail later.

The illustrated child seat body 11 includes a support base 20 disposed on a seating surface SS of the seat S, and a seat unit 30 supported on the support base 20. The fixing unit 50 is held by the support base 20, and is coupled to the anchor a to fix the support base 20 to the seat S. As shown in fig. 2, the seat unit 30 is supported by the support base 20 so as to be adjustable in backrest angle, that is, so as to be variable in reclining angle.

In addition, the child seat 10 has support legs 40 extending from the support base 20 of the child seat main body 11. As shown in fig. 1, the support legs 40 extend to a floor surface F of the vehicle that supports the seat S of the vehicle, and support a front portion of the child seat main body 11 (support base 20) from below.

In the present specification, unless otherwise specified, terms such as "up", "down", "front", "rear", "vertical direction", and "front-rear direction" relating to the child seat 10 and the respective parts thereof refer to "up", "down", "front", and "rear" with reference to normal running of the vehicle. The width direction is a lateral direction and is a direction orthogonal to both the "up-down direction" and the "front-rear direction".

First, the parts of the child seat body 11 will be described in more detail with reference to fig. 1 to 5. Fig. 3 is a perspective view showing the support base 20 of the child seat 10 of fig. 1, and fig. 4 is a perspective view showing the bottom member 21 of the support base 20 of fig. 3 together with the fixing unit 50, the support legs 40, the shaft 33, and the engaging shaft 34 of the seat unit 30. Fig. 5 is a perspective view showing a bottom side of the seat unit 30.

First, the support base 20 will be described with reference to fig. 1 to 4. As shown in fig. 1, the support base 20 includes a bottom member 21 disposed on a seat surface SS of the vehicle seat S, and a cover member 22 covering the bottom member 21 from above. The base member 21 and the cover member 22 are formed of a resin such as polypropylene. As clearly shown in fig. 3 and 4, the bottom member 21 holds one and the other of the pair of fixing units 50 at one and the other of both ends of the bottom member 21 in the width direction. Further, a support leg 40 is connected to the front end of the bottom member 21.

As shown in fig. 3 and 4, the bottom member 21 has a holder member 23 that holds the seat unit 30. The holder member 23 is fixed to the center of the bottom member 21 in the width direction near the rear end of the bottom member 21. The holder member 23 is provided with a guide hole 23h, and the guide hole 23h penetrates the holder member 23 in the width direction and extends in the front-rear direction of the bottom member 21. The shaft 33 held by the seat unit 30 passes through the guide hole 23h, and thereby the seat unit 30 is connected to the support base 20 so as to be movable in the front-rear direction with respect to the support base 20.

As shown in fig. 4, the support table 20 further has the 2

nd holder members

24, 24 provided on the upper surface of each fixing unit 50. Each 2 nd holder member 24 is provided with a bottomed guide hole 24h for accommodating an end portion of the shaft 33. The guide hole 24h extends in the front-rear direction of the bottom member 21. The seat unit 30 is also connected to the support base 20 so as to be movable in the front-rear direction with respect to the support base 20 by inserting each end portion of the shaft 33 into the corresponding guide hole 24h of the 2 nd holder member 24.

In addition, the portion 21s of the upper surface 21a of the bottom member 21 on which the seat unit 30 slides is bent, and the

guide holes

23h, 24h are also bent. Further, the more the seat unit 30 moves forward, the more the seat unit 30 tilts rearward, the more the seat unit 30 moves rearward, and the more the seat unit 30 stands up. Accordingly, the seat unit 30 performs backrest angle adjustment as it moves forward on the bottom member 21 (see fig. 2).

In addition, a regulating portion 25 is formed in the bottom member 21, and the regulating portion 25 regulates the movement of the seat unit 30 in the front-rear direction with respect to the support base 20. The regulating portion 25 is provided at the widthwise center of the bottom member 21. The restricting portion 25 includes a pair of protruding

portions

26, 26 extending in the front-rear direction and separated from each other. Grooves 26g are provided in the respective protrusions 26, and the grooves 26g can receive an engagement shaft 34 of a seat unit 30, which will be described later, from above. The plurality of grooves 26g are provided separately in the front-rear direction of the bottom member 21. Accordingly, by adjusting the position of the seat unit 30 relative to the support base 20 in the front-rear direction, the backrest angle adjustment angle of the seat unit 30 relative to the support base 20 can be adjusted.

As shown in fig. 3, an opening 22h for exposing the regulating portion 25 is provided at the center of the cover member 22. The protruding

portions

26, 26 of the restricting portion 25 are engaged with the engaging shaft 34 of the seat unit 30 through the opening 22 h.

Next, the seat unit 30 will be described with reference mainly to fig. 1 and 3. As shown in fig. 1, the seat unit 30 includes a base 31 supported on the support table 20 and a seat main body 38 connected to the base 31.

As clearly shown in fig. 5, a pair of

rail members

32 and 32 sliding on the bottom member 21 of the support table 20 are provided at a lower portion of the base 31. The

rail members

32, 32 hold the shaft 33 connecting the base 31 and the support table 20. The shaft 33 extends in the width direction, and passes through the guide hole 23h of the holder member 23 between the rail members 32, 32 (see fig. 4).

The

rail members

32 and 32 hold an engaging shaft 34 extending in the width direction in front of the shaft 33. The engagement shaft 34 engages with the protruding

portions

26, 26 of the support base 20. Specifically, the engagement shaft 34 is housed in the groove 26g of the protruding

strip

26, 26. As shown in fig. 4, the engagement shaft 34 engages with the protruding

portions

26, 26 of the support base 20, thereby restricting the movement of the base 31 in the front-rear direction with respect to the support base 20. When the operating mechanism 35 provided in the seat body 38 is operated, the engaging shaft 34 moves upward relative to the

rail members

32, 32 and disengages from the grooves 26g of the protruding

portions

26, 26. When the engagement shaft 34 is disengaged from the groove 26g of the protruding portion 26, the engagement between the engagement shaft 34 and the protruding

portion

26, 26 is released, and the seat main body 38 can move in the front-rear direction with respect to the support base 20. The engagement shaft 34 is biased by a biasing mechanism, not shown, and when the operation mechanism 35 is stopped, the engagement shaft 34 moves downward.

Next, the support leg 40 will be explained. As shown in fig. 1 and 3, the support leg 40 includes: a fitting portion 41 fitted to the front end of the bottom member 21; and a leg portion 42 fixed to the fitting portion 41. As shown in fig. 1, the leg portion 42 extends to the floor surface F of the vehicle. As a result, the support legs 40 support the front end portion of the bottom member 21 disposed on the seating surface SS of the vehicle seat S from the floor surface F. In addition, in order to ensure versatility with respect to the vehicle, the leg portion 42 is configured such that the length thereof is adjustable.

Next, the fixing unit 50 will be described mainly with reference to fig. 6 to 14.

As shown in fig. 6, the fixing unit 50 is held to the child seat main body 11. The fixing unit 50 is coupled to a holder a provided in the seat S, and thereby can fix the child seat body 11 to the seat.

In the illustrated child seat 10, the child seat main body 11 holds the pair of fixing units 50 apart in the width direction. The pair of fixing units 50 has the following structure: the plane passing through the center in the width direction and along the front-back direction and the up-down direction is symmetrical as the center. Next, the fixing unit 50 positioned on the left side will be described. In fig. 7, the fixing means 50 on the right side is not shown.

In order to clarify the directional relationship between fig. 6 to 14, in these drawings, the front-rear direction DX, the width direction DY, and the up-down direction DZ are indicated by arrows in common directions between the drawings. The tip side of the arrow is the side of respective directions DX, DY, DZ. The side on the tip side of the arrow in the front-rear direction DX is the front side, and the side on the tip side of the arrow in the up-down direction DZ is the upper side. In addition, with reference to the left-side fixed unit shown in fig. 6 to 14, the side on the tip side of the arrow in the width direction DY is the outer side in the width direction, that is, the side away from the center in the width direction. Further, as shown in fig. 11 to 14, arrows extending to the back side of the drawing sheet in the direction perpendicular to the drawing sheet are indicated by X-shaped marks provided on the circles. For example, as shown in fig. 6, an arrow from the paper surface toward the front in a direction perpendicular to the paper surface of the drawing is denoted by a mark provided with a dot in a circle.

As shown in fig. 8, the fixing unit 50 is a rod-shaped component extending in the front-rear direction DX. The fixing unit 50 linearly extends in the front-rear direction DX. The fixing unit 50 has: a link 60 connected to the anchor A of the seat S; a connection releasing member 70 for releasing the connection between the connector 60 and the fastener a by operating the connection releasing member 70; and an intermediate frame member 80 located between the coupler 60 and the coupling releasing member 70. The link 60, the intermediate frame member 80, and the link releasing member 70 are arranged in this order from the rear to the front side in the front-rear direction DX on a straight line in the front-rear direction DX. As shown in fig. 10, the fixing unit 50 further includes, as other main components, an operation restricting member 79 and a restriction releasing member 75, the operation restricting member 79 restricting the operation of the coupling releasing member 70; the restriction of the operation of the coupling releasing member 70 is released by operating the restriction releasing member 75 to act on the operation restricting member 79.

As shown in fig. 6 and 7, the link 60 is located rearward of the child seat body 11 in the front-rear direction DX. The link releasing member 70 is located forward of the link 60 in the front-rear direction DX and is exposed from the child seat body 11. The coupling release member 70 itself functions as an operation lever for operating the coupling 60, and projects rearward in the front-rear direction DX from the child seat body 11. The child seat main body 11 holds the intermediate portion in the front-rear direction DX of the fixing unit 50. The child seat main body 11 holds the intermediate portion of the fixing unit 50 from the periphery.

In the illustrated example, the child seat main body 11 is provided with a holding hole 27 through which the fixing unit 50 passes. The holding hole 27 is provided in the support base 20. The support table 20 has holding holes 27 extending in the front-rear direction DX formed at a pair of positions separated in the width direction DY. The fixing units 50 extend through the holding holes 27 and protrude forward and backward from the support base 20. In the example shown in fig. 6 and 7, the entire coupler 60 protrudes rearward from the holding hole 27. The coupling release member 70 projects forward from the holding hole 27, but the rear end of the coupling release member 70 is positioned in the holding hole 27. The coupling releasing member 70 extends forward from the intermediate frame member 80 in the fixing unit 50. The front end of the intermediate frame member 80 is located inside the child seat main body 11, i.e., inside the holding hole 27.

The child seat main body 11 supports the fixing unit 50 so as to be movable in the front-rear direction. The position at which the fixing unit 50 is held by the child seat main body 11 is adjustable in the front-rear direction DX. As shown in fig. 9 and 4, the child seat main body 11 has a position adjustment mechanism 45 that can change the holding position of the fixing unit 50. The position adjustment mechanism 45 includes an operating lever member 46 and a restricting member 47. The position adjustment mechanisms 45 are provided corresponding to the respective fixing units 50. That is, the pair of position adjustment mechanisms 45 are provided separately in the width direction. The operating lever member 46 is provided to be operable. The restricting member 47 is also operated in accordance with the operation of the operating lever member 46. The restricting member 47 acts on the fixing unit 50 by operating.

The illustrated operating lever member 46 is provided swingably to the 2 nd holder member 24 disposed on the corresponding side in the width direction. As shown in fig. 6 and 7, a part of the operating lever member 46 is exposed from the support base 20 as an operating portion 46 a. The user can operate the operating lever member 46 by pressing the operating portion 46 a. As shown in fig. 9, the restricting member 47 is swingably connected to the operating lever member 46. As shown in fig. 4, the restricting member 47 is supported by the 2 nd holder member 24 so as to be movable only in the vertical direction DZ. The regulating member 47 is movable in the vertical direction DZ in accordance with the swing operation of the operating lever member 46.

The regulating member 47 is biased in a direction approaching the fixing unit 50, specifically, downward by a biasing member such as a spring, not shown. The regulating member 47 has a pin-shaped tip portion. The restricting member 47 is positioned downward, and thereby the pin-shaped tip end portion of the restricting member 47 is inserted into any one of the plurality of positioning holes 81 opened in the upper surface of the fixing unit 50. The plurality of positioning holes 81 are arranged in the front-rear direction DX. In the illustrated example, the positioning hole 81 is provided in the intermediate frame member 80. By inserting the restricting member 47 into the positioning hole 81, the relative movement of the fixing unit 50 with respect to the child seat main body 11 in the front-rear direction DX is restricted. On the other hand, the operating lever member 46 is swung by operating the operating portion 46a, and the regulating member 47 is moved upward and separated from the positioning hole 81. At this time, the fixing unit 50 is relatively movable in the front-rear direction DX with respect to the child seat body 11. By appropriately selecting the positioning hole 81 into which the restricting member 47 is inserted, the position in the front-rear direction DX in which the fixing unit 50 is held by the child seat main body 11 can be adjusted.

Next, each component of the fixing unit 50 will be described. First, the coupling 60 will be described with reference mainly to fig. 11 to 13.

As shown in fig. 6 and 7, the coupler 60 is located at the rear end of the fixing unit 50. The link 60 can be coupled to a anchor a provided on the seat S of the vehicle. The link 60 extends in the front-rear direction DX in a side view, and receives and holds the anchor a by a notch 61a opened in the rear. As the holder a, various structures can be adopted, and as shown in fig. 6, a shaft extending in the width direction DY can be exemplified. As a typical example of the anchor a configured by a shaft fixed to the vehicle together with the seat S, an anchor that conforms to the ISOFIX standard and is applicable to various automobiles can be used.

The connector 60 shown in fig. 11 to 13 includes: a connector frame 61 forming a notch 61 a; a link member 62 rotatably held by the link frame 61; a coupling member biasing member 64 that acts on the coupling member 62; and a release operation member 65 slidably held by the link frame 61. The entire link frame 61 has a rectangular parallelepiped shape elongated in the front-rear direction DX. The notch 61a opens on the rear side in the front-rear direction DX and on both sides in the width direction DY. The notch 61a can receive the shaft-like holder a extending in the width direction DY from behind. The coupler frame 61 can be made of a metal plate material, for example.

The coupling member biasing member 64 is formed of, for example, a torsion spring, and biases the coupling member 62 to rotate. The coupling member 62 is rotatable about a rotation axis RA defined by the rotation shaft member 61s between a release position shown in fig. 11 and a holding position shown in fig. 12. The coupling member 62 is biased by a coupling member biasing member 64 from the holding position of fig. 12 to the release position of fig. 11. The coupling member 62 includes a coupling arm portion 63A, an operation arm portion 63B, and a regulating arm portion 63C. As shown in fig. 12, a groove 62a for accommodating the shaft-like anchor a is provided between the connecting arm portion 63A and the operating arm portion 63B. The

arm portions

63A, 63B, 63C extend substantially radially from the rotation center RA of the coupling member 62.

The release operation member 65 is supported by the link frame 61 so as to be movable in the front-rear direction DX. The release operation member 65 is movable in the front-rear direction DX between at least a coupling position shown in fig. 12 and a release position shown in fig. 13. The release operation member 65 is biased from the front to the rear of the front-rear direction DX by a release operation member biasing member, not shown. The release operation member 65 is fixed to the intermediate transmission member 85. That is, the release operation member 65 is biased from the release position shown in fig. 13 to the coupling position shown in fig. 12.

The coupling with the anchor a is released by operating the release operation member 65, and the illustrated coupling member 60 is held in the state shown in fig. 11. Further, by inserting the anchor a into the notch 61a, the coupler 60 is held in the state shown in fig. 12 coupled to the anchor a. The release operation member 65 is moved forward in the front-rear direction DX from the state shown in fig. 12 to the state shown in fig. 13, thereby releasing the coupling between the coupling 60 and the anchor a. Next, the operation of the coupling 60 will be described.

In a state where the coupling with the anchor a is released, the coupling member 62 is located at the release position shown in fig. 11. The coupling arm portion 63A of the coupling member 62 located at the release position shown in fig. 11 is not located inside the notch 61a but located outside the notch 61a in a side view. On the other hand, the operation arm portion 63B of the coupling member 62 located at the release position in fig. 11 crosses the notch 61a, and extends obliquely with respect to the front-rear direction DX from the rotation center of the coupling member 62 toward the rear side in the front-rear direction. In addition, the restricting arm portion 63C of the coupling member 62 located at the release position in fig. 11 extends obliquely with respect to the front-rear direction DX toward the front side in the front-rear direction from the rotation center of the coupling member 62 in a side view. At this time, the end edge of the regulating arm portion 63C extends in the vertical direction and is directed forward in the front-rear direction DX. The release operation member 65 is biased to the rear side from the front side in the front-rear direction DX. Therefore, the coupling member 62 is biased clockwise in fig. 11 by the biasing force from the coupling member biasing member 64 and also by the pressing force from the release operation member 65, and is stably held at the release position.

When the shaft-like anchor a is inserted into the notch 61a from the rear, the anchor a contacts the operation arm portion 63B, and presses the operation arm portion 63B to the front side in the front-rear direction DX, whereby the coupling member 62 rotates counterclockwise in fig. 11. As the coupling member 62 rotates counterclockwise, the release operation member 65 is temporarily pushed forward in the front-rear direction DX by the edge of the restricting arm portion 63C. Then, as shown in fig. 13, the coupling member 62 is pivoted to a position where the restricting arm portion 63C does not restrict the release operation member 65 from moving to the rear side in the front-rear direction DX. At this time, the release operation member 65 is moved to the rear side in the front-rear direction DX by the biasing force from the release operation member biasing member, not shown. As a result, as shown in fig. 12, the release operation member 65 enters below the regulating arm portion 63C. The release operation member 65 is held at the coupling position by a biasing force from a release operation member biasing member, not shown.

As shown in fig. 12, when the release operation member 65 enters below the restricting arm portion 63C, the release operation member 65 contacts the restricting arm portion 63C, and the clockwise rotation of the release operation member 65 is restricted. Accordingly, even if the pushing force for pushing the anchor a into the notch 61a is released, the coupling member 62 is held at the holding position shown in fig. 12.

The coupling arm portion 63A of the coupling member 62 located at the release position shown in fig. 12 extends in the vertical direction DZ across the notch 61a in a side view. Therefore, the anchor a is restricted from being detached from the groove 62a by the coupling arm portion 63A. The release operation member 65 is held at the coupling position of fig. 12, and the coupling member 62 is held at the holding position of fig. 12, whereby the shaft-like holder a is stably held in the notch 61 a. In this way, the coupling member 60 holds the anchor a and thereby couples the anchor a. On the other hand, as shown in fig. 13, by pulling the release operation member 65 forward in the front-rear direction DX to the position of fig. 13 where the rotation of the arm portion 63C to the release position is not restricted, the coupling of the coupling member 60 and the anchor a can be released.

Next, the intermediate frame member 80 and the intermediate transmission member 85 will be described. As shown in fig. 8 and 9, the rear end of the intermediate frame member 80 is connected to the coupler frame 61 of the coupler 60. The intermediate frame member 80 and coupler frame 61 are secured to one another. The intermediate frame member 80 is made of, for example, a metal tubular member. As described above, the plurality of positioning holes 81 are provided at equal intervals in the front-rear direction DX on the upper surface of the intermediate frame member 80.

As shown in fig. 10 to 13, the rear end of the intermediate transmission member 85 is connected to the release operation member 65 of the coupling 60. The intermediate transmission member 85 is fixed to the release operation member 65 by a fixing member such as a spring. The intermediate transmission member 85 is movably supported by the intermediate frame member 80.

The intermediate transmission member 85 is movable relative to the intermediate frame member 80 in the front-rear direction DX. For example, it may be: one of the intermediate frame member 80 and the intermediate transmission member 85 is provided with a guide elongated hole extending in the front-rear direction DX, and the other of the intermediate frame member 80 and the intermediate transmission member 85 is provided with a guide introduction portion inserted into the guide elongated hole and movable in the guide hole in the longitudinal direction of the guide elongated hole. With this configuration, the relative movement of the intermediate frame member 80 and the intermediate transmission member 85 in the front-rear direction DX can be stably guided. In the illustrated fixing unit 50, as shown in fig. 10, a 1 st guide long hole 86 extending in the front-rear direction DX is provided in the intermediate transmission member 85. As shown in fig. 8 and 9, a 1 st guide insertion portion 82 in the form of a pin inserted into the 1 st guide long hole 86 is provided in the intermediate frame member 80. The intermediate transmission member 85 can be manufactured as a resin molded part, for example.

Next, the coupling releasing member 70 will be described. The coupling release member 70 extends from the intermediate frame member 80 to the front side in the front-rear direction DX. The coupling/releasing member 70 is movably supported by the intermediate frame member 80. In the illustrated example, the coupling release member 70 is movable relative to the intermediate frame member 80 in the front-rear direction DX. As described above, the intermediate frame member 80 is fixed to the child seat main body 11 via the position adjustment mechanism 45. Therefore, the coupling releasing member 70 can be moved relative to the child seat main body 11.

As shown in fig. 6 and 7, the illustrated coupling releasing member 70 extends from the holding hole 27 of the child seat body 11 to the front side in the front-rear direction DX. As shown in fig. 7 and 8, the coupling releasing member 70 includes: a coupling release body portion 71 that extends in the front-rear direction DX and is inserted into the holding hole 27 of the child seat body 11 at the rear; and a connection releasing operation portion 72 located in front of the connection releasing body portion 71 and bulging outward in the width direction. The coupling release operation portion 72 includes an operation surface 72a that extends in the width direction DY and faces rearward in the front-rear direction DX. The coupling release operation portion 72 has a width in the width direction DY that increases from the front side toward the rear side in the front-rear direction DX.

In the illustrated fixing unit 50, as shown in fig. 9, the rear portion of the coupling release body portion 71 has a cylindrical shape having a quadrangular cross section. More specifically, the coupling release body 71 includes: a main wall portion 71a facing outward in the width direction DY; an opposing wall portion 71b that faces the main wall portion 71a in the width direction DY; and a pair of side wall portions 71C connecting the main wall portion 71a and the opposing wall portion 71 b. The pair of side walls 71C are arranged to face each other in the vertical direction DZ. The opposing wall portion 71b is provided only at a rear portion in the front-rear direction DX. The front end portion of the intermediate frame member 80 is inserted into the cylindrical portion of the coupling release member 70. With this configuration, the relative movement of the intermediate frame member 80 and the coupling release member 70 in the front-rear direction DX can be stably guided. The coupling releasing member 70 can be manufactured as a resin molded portion, for example.

In addition, it may be: one of the intermediate frame member 80 and the coupling release member 70 is provided with a guide elongated hole extending in the front-rear direction DX, and the other of the intermediate frame member 80 and the coupling release member 70 is provided with a guide introduction portion that is inserted into the guide elongated hole and is movable in the guide hole in the longitudinal direction of the guide elongated hole. With this configuration, the relative movement of the intermediate frame member 80 and the coupling release member 70 in the front-rear direction DX can be stably guided. In the illustrated fixing unit 50, as shown in fig. 14, a 2 nd guide long hole 83 extending in the front-rear direction DX is provided in the intermediate frame member 80. As shown in fig. 8, 9, and 14, the 2 nd guide insertion portion 73 in a pin shape inserted into the 2 nd guide long hole 83 is provided in the coupling release member 70.

The intermediate transmission member 85 transmits the movement of the coupling releasing member 70 to the coupling 60. Accordingly, by operating the coupling release member 70, the release operation member 65 of the coupling 60 is operated via the intermediate transmission member 85, and the coupling between the coupling 60 and the anchor a is released. As described above, the release operation member 65 of the link 60 and the intermediate transmission member 85 fixed to the release operation member 65 are moved forward in the front-rear direction DX, whereby the link 60 and the anchor a can be released from each other. In the illustrated example, the coupling between the coupling 60 and the anchor a can be released by operating the coupling release member 70 to move the coupling release member 70 forward in the front-rear direction DX and moving the release operation member 65 forward in the width direction DY via the intermediate transmission member 85.

Therefore, the coupling releasing member 70, which is movable with respect to the intermediate frame member 80, is connected to the intermediate transmission member 85. However, in the illustrated example, the coupling/decoupling member 70 and the intermediate transmission member 85 are connected to each other so as to be movable by a predetermined length relative to each other in the moving direction when the coupling/decoupling member 70 is operated. In the illustrated example, the coupling release member 70 and the intermediate transmission member 85 are connected to each other so as to be movable relative to each other by a predetermined length in the front-rear direction DX.

As a structure that enables the coupling release member 70 and the intermediate transmission member 85 to move relative to each other in the front-rear direction DX, there may be: a long hole extending in the front-rear direction DX is provided in one of the coupling release member 70 and the intermediate transmission member 85; the other of the coupling releasing member 70 and the intermediate transmission member 85 is provided with an insertion portion that is movably inserted into the elongated hole. In the illustrated fixing unit 50, as shown in fig. 10 and 14, the intermediate transmission member 85 is provided with a 3 rd long guide hole 87, and the 2 nd guide insertion portion 73 provided in the coupling release member 70 is inserted into the 3 rd long guide hole 87. The 2 nd guide insertion portion 73 is movable in the 3 rd guide long hole 87 along the longitudinal direction DX, i.e., the front-rear direction DX of the 3 rd guide long hole 87.

As described above, the intermediate transmission member 85 transmits the movement of the coupling releasing member 70 to the coupling 60. Therefore, the length over which the coupling release member 70 and the intermediate transmission member 85 can move relative to each other in the front-rear direction DX is within a certain range, and in particular, is smaller than the length over which the coupling release member 70 and the intermediate frame member 80 can move relative to each other in the front-rear direction DX. Accordingly, when the coupling release member 70 is moved relative to the intermediate frame member 80 in the front-rear direction DX, the intermediate transmission member 85 can be moved in the front-rear direction DX by a length smaller than the movement length of the coupling release member 70. In the illustrated example, the 2 nd guide insertion portion 73 of the coupling releasing member 70 is inserted into the 1 st guide insertion portion 82 of the intermediate frame member 80 and the 3 rd guide long hole 87 of the intermediate transmission member 85. The length of the 3 rd guide long hole 87 provided in the intermediate transmission member 85 in the front-rear direction DX is shorter than the length of the 1 st guide insertion portion 82 provided in the intermediate frame member 80 in the front-rear direction DX. Therefore, the coupling release member 70 initially moves relative to both the intermediate frame member 80 and the intermediate transmission member 85 in the front-rear direction DX, and thereafter, can move relative to the intermediate frame member 80 in the front-rear direction DX in synchronization with the intermediate transmission member 85.

In the illustrated example, the direction of the biasing force applied to the coupling releasing member 70 is opposite to the direction of the movement when the coupling releasing member 70 is operated. Therefore, the coupling/decoupling member 70, which can move relative to the intermediate transmission member 85 by a predetermined length, can be effectively prevented from rattling relative to the intermediate transmission member 85. As a specific configuration, as shown in fig. 10, the 1 st biasing member 51 is provided between the coupling releasing member 70 and the intermediate transmission member 85. The 1 st urging member 51 is formed of an elastic member such as a tension spring or an elastic structure. The 1 st biasing member 51 is connected to the 1 st biasing member supporting portion 74A of the coupling releasing member 70 and the tip end portion of the intermediate transmission member 85. Therefore, the coupling release member 70 is biased to the rear side in the front-rear direction DX by the 1 st biasing member 51. According to the 1 st urging member 51, when the coupling release member 70 is pulled forward in the front-rear direction DX, the coupling release member 70 first moves forward and backward relative to both the intermediate frame member 80 and the intermediate transmission member 85, and thereafter moves forward and backward relative to the intermediate frame member 80 in synchronization with the intermediate transmission member 85.

Next, the restriction releasing member 75 and the operation restricting member 79 will be described. As described above, the operation restricting member 79 restricts the operation of the coupling releasing member 70. On the other hand, the restriction of the operation of the coupling releasing member 70 is released by operating the restriction releasing member 75 to act on the operation restricting member 79.

In particular, the movement restricting member 79 restricts the relative movement of the coupling releasing member 70 with respect to the intermediate frame member 80. As a specific configuration, there may be: the restriction long hole 56 is provided in one of the coupling/decoupling member 70 and the intermediate frame member 80, and the other of the coupling/decoupling member 70 and the intermediate frame member 80 supports the movement restriction member 79 so as to be movable in the restriction long hole 56. In this example, the restriction long hole 56 has: a 1 st elongated hole 56a extending in a moving direction when the connection releasing member 70 is operated; and a 2 nd elongated hole 56b extending in a direction orthogonal to the moving direction when the coupling releasing member 70 is operated. The 1 st long hole portion 56a and the 2 nd long hole portion 56b are connected to each other. The movement restricting member 79 is supported by one of the coupling/releasing member 70 and the intermediate frame member 80 so as to be movable in a direction orthogonal to the movement direction when the coupling/releasing member 70 is operated, and is inserted into the restriction long hole 56 so as to be movable. In this example, the following may be used: by operating the restriction releasing member 75, the operation restricting member 79 is moved in a direction orthogonal to the moving direction when the coupling releasing member 70 is operated.

In the illustrated fixing unit 50, as shown in fig. 8 to 10, the restriction long hole 56 is provided in the coupling release member 70. The long restriction holes 56 are provided at positions facing each other in the width direction DY of the main wall portion 71a and the facing wall portion 71b of the coupling release body portion 71. The 1 st slot portion 56a of the restriction slot 56 extends in the front-rear direction DX. The 2 nd long hole portion 56b of the restriction long hole 56 extends in the vertical direction DZ. The front end of the 1 st elongated hole 56a in the front-rear direction DX and the upper end of the 2 nd elongated hole 56b in the vertical direction DZ are connected to each other.

The operation restricting member 79 is configured as a pin-shaped member extending in the width direction. The operation restricting member 79 is supported by the intermediate frame member 80 so as to be movable in the vertical direction. The intermediate frame member 80 has long support holes 84 formed in a pair of wall portions facing each other in the width direction DY (see fig. 14). The long support holes 84 extend in the vertical direction, and the movement restricting member 79 is movable in the vertical direction within the long support holes 84. The movement restricting member 79 passes through the support long hole 84 of the intermediate frame member 80 and also passes through the restriction long hole 56 of the coupling releasing member 70. The No. 2 long hole portion 56b of the restriction long hole 56 and the support long hole 84 extend in the same height range in the vertical direction DZ. The 1 st elongated hole portion 56a of the restriction elongated hole 56 is located at the same height as the upper end portion of the support elongated hole 84. By positioning the operation limiting member 79 at the upper end portion of the support long hole 84, the operation limiting portion 79 can move in the 1 st long hole portion 56a of the limiting long hole 56. That is, by moving the operation restricting member 79 toward the upper end portion of the support long hole 84, the coupling release member 70 can be moved relative to the intermediate frame member 80 in the front-rear direction DX.

The restriction releasing member 75 operates to act on the operation restricting member 79. The operation restricting member 79 positioned in the 2 nd long hole portion 56b is moved to the 1 st long hole portion 56a by operating the illustrated restriction releasing member 75. As a specific configuration, as shown in fig. 14, the restriction releasing member 75 is formed with a long drive hole 78 through which the operation restricting member 79 passes. The long drive hole 78 includes a 1 st hole 78a and a 3 rd hole 78c extending in the front-rear direction DX which is the moving direction when the coupling releasing member 70 is operated, and a 2 nd hole 78b connecting the 1 st hole 78a and the 2 nd hole 78b to each other. Hole 2 b is inclined with respect to front-rear direction DX. The 1 st hole portion 78a and the 2 nd hole portion 78b are located at different heights in the up-down direction DZ. The 1 st hole portion 78a is located at the same height as the lower end portion of the long restriction hole 56, and the 3 rd hole portion 78c is located at the same height as the upper end portion of the long restriction hole 56. In the illustrated example, the 1 st hole portion 78a is located on the rear side in the front-rear direction DX, and the 3 rd hole portion 78c is located on the front side in the front-rear direction DX. The 2 nd hole portion 78b is positioned between the 1 st hole portion 78a and the 3 rd hole portion 78c in the front-rear direction DX. In this example, the coupling canceling member 70 can be relatively moved in the front-rear direction DX with respect to the intermediate frame member 80 by moving the restriction canceling member 75 in the front-rear direction DX to the rear side and moving the operation restricting member 79 upward.

That is, in the illustrated example, the movement direction of the coupling release member 70 when the coupling release member 70 is operated to release the coupling of the coupling unit 60 and the anchor a is parallel to the movement direction of the restriction release member 75 when the restriction release member 75 is operated to release the restriction on the operation of the coupling release member 70, and is along the front-rear direction DX. Therefore, the operability when both the coupling releasing member 70 and the restriction releasing member 75 are operated is excellent. The direction of movement of the coupling release member 70 when the coupling release member 70 is operated to release the coupling of the coupling member 60 and the anchor a is opposite to the direction of movement of the restriction release member 75 when the restriction release member 75 is operated to release the restriction on the operation of the coupling release member 70. Therefore, it is possible to effectively avoid the unintentional release of the coupling between the coupling member 60 and the anchor a due to an erroneous operation.

In the illustrated example, the movement direction of the coupling release member 70 when the coupling release member 70 is operated to release the coupling of the coupling member 60 and the anchor a is in the front-rear direction parallel to the movement direction of the release operation member 65 from the coupling position in fig. 12 to the release position in fig. 13. At this time, the direction of movement of the coupling release member 70 is the same as the direction of movement of the release operation member 65. According to this example, the size increase of the fixing unit 50 can be effectively suppressed.

In the illustrated fixing unit 50, as shown in fig. 9 and 10, the restriction releasing member 75 is movably supported by the coupling releasing member 70. The restriction releasing member 75 is elongated and extends in the front-rear direction DX. The restriction releasing member 75 passes through the inside of the cylindrical portion of the coupling releasing member 70 located on the rear side in the front-rear direction DX. As shown in fig. 6 to 9, the front end portion of the restriction releasing member 75 in the front-rear direction DX is exposed from the coupling releasing member 70. An opening 70a is formed at the front end of the coupling release member 70 in the front-rear direction DX. The restriction releasing member 75 has the restriction releasing operation portion 76 exposed from the opening 70a as a front end portion in the front-rear direction DX thereof. The restriction releasing operation portion 76 of the restriction releasing member 75 exposed through the opening 70a of the coupling releasing member 70 can be pressed toward the rear side in the front-rear direction DX.

As shown in fig. 9 and 10, the restriction releasing member 75 is provided with an opening 75 a. The coupling releasing member 70 has a 2 nd biasing member supporting portion 74B protruding in the width direction DY at a position inside the opening 75 a. The 2 nd biasing member 52 is provided in the opening 75 a. The 2 nd urging member 52 is formed of an elastic member or an elastic structure such as a compression spring, for example. The 2 nd biasing member 52 is positioned between the 2 nd biasing member supporting portion 74B of the coupling release member 70 and the restriction release member 75. The restriction releasing member 75 is biased forward in the front-rear direction with respect to the coupling releasing member 70 by the 2 nd biasing member 52.

Next, the operation of the fixing unit 50 when the coupling with the anchor a of the vehicle by the coupling 60 is released will be described.

First, in a state where the link 60 is coupled to the anchor a, as shown in fig. 12, the release operation member 65 of the link 60 and the intermediate transmission member 85 fixed to the release operation member 65 are positioned on the rear side in the front-rear direction DX. As shown in fig. 13, the release operation member 65 is moved forward in the front-rear direction DX, whereby the coupling with the anchor a by the coupling 60 can be released. The release operation member 65 is moved to the front side by operating the coupling release member 70.

However, as described above, the restriction releasing member 75 is biased toward the front side in the front-rear direction DX by the 2 nd biasing member 52 with respect to the coupling releasing member 70. The restriction releasing member 75 is positioned on the front side in the front-rear direction DX with respect to the coupling releasing member 70, and thereby, as shown in fig. 14 (a), the 1 st hole portion 78a of the drive long hole 78 of the restriction releasing member 75 overlaps the support long hole 84 of the intermediate frame member 80 in the width direction DY. That is, the operation restricting member 79 supported in the long support hole 84 is located at the lower end portion of the long support hole 84 intersecting the 1 st hole portion 78 a. At this time, the operation restriction member 79 passes through the restriction long hole 56 of the coupling release member 70 at the lower end portion of the 2 nd long hole 56 b. Therefore, in the state of fig. 14 (a), the movement restricting member 79 comes into contact with the wall portion defining the 2 nd elongated hole portion 56b, thereby causing relative movement of the coupling releasing member 70 with respect to the intermediate frame member 80 in the front-rear direction DX.

Therefore, the operation restriction member 79 releases the restriction of the operation of the coupling release member 70 by operating the restriction release member 75 before the coupling release member 70 is operated. Specifically, the restriction releasing member 75 is pressed toward the rear side in the front-rear direction DX with respect to the coupling releasing member 70. As shown in fig. 14 (B), the movement restricting member 79, which couples the long restriction holes 56 of the release member 70 and the long support holes 84 of the intermediate frame member 80, moves from the 1 st hole portion 78a to the 3 rd hole portion 78c through the 2 nd hole portion 78B in the long drive hole 78 of the release member 75. That is, the operation restricting member 79 is guided by the drive long hole 78 and moves upward in the vertical direction DZ in the 1 st long hole portion 56a of the restriction long hole 56 and in the support long hole 84. As shown in fig. 14 (B), the movement restricting member 79 reaches the 2 nd long hole portion 56B from the 1 st long hole portion 56a of the restriction long hole 56. As shown in fig. 14 (B), the operation restricting member 79 finally reaches the tip of the drive long hole 78.

As described above, the coupling release member 70 and the intermediate transmission member 85 are connected to each other so as to be movable relative to each other in the front-rear direction DX. However, the coupling releasing member 70 is held at a position close to the intermediate transmission member 85 by the 1 st biasing member 51. That is, when the restriction releasing member 75 is pressed rearward, the coupling releasing member 70 is also pressed rearward via the restriction releasing member 75, but the coupling releasing member 70 is in a state of being moved rearward by the 1 st urging member 51. Therefore, the restriction releasing member 75 can be operated stably in a state where the coupling releasing member 70 is stopped.

Next, in a state where the coupling release member 75 is kept pressed rearward with respect to the coupling release member 70, that is, in a state where the relative positions of the coupling release member 70 and the restriction release member 75 are kept, the coupling release member 70 is moved forward in the front-rear direction DX together with the restriction release member 75. Accordingly, the coupling release member 70 moves relative to the intermediate frame member 80 toward the front side in the front-rear direction DX. Along with this relative movement, the movement restricting member 79 supported by the support long hole 84 of the intermediate frame member 80 moves in the 1 st long hole portion 56a extending in the front-rear direction DX among the restriction long holes 56 of the coupling releasing member 70.

The coupling releasing member 70 is connected to the intermediate transmission member 85 via the 2 nd guide insertion portion 73 inserted into the 3 rd guide long hole 87 of the intermediate transmission member 85. When the coupling releasing member 70 moves forward by a certain length with respect to the intermediate transmission member 85, in other words, when the 2 nd guide insertion portion 73 moves by a movable length within the 3 rd guide long hole 87, as shown in fig. 14 (C), the 2 nd guide insertion portion 73 comes into contact with a wall portion that divides the 3 rd guide long hole 87.

The 2 nd guide insertion portion 73 of the coupling release member 70 also passes through the 2 nd guide long hole 83 of the intermediate frame member 80. The length of the 2 nd guide long hole 83 of the intermediate frame member 80 in the front-rear direction DX is longer than the length of the 3 rd guide long hole 87 of the intermediate transmission member 85 in the front-rear direction DX. Therefore, in the state of fig. 14 (C), the 2 nd guide insertion portion 73 of the coupling release member 70 does not contact the wall portion defining the 2 nd guide long hole 83. Therefore, the coupling release member 70 can move further to the front side in the front-rear direction DX with respect to the intermediate frame member 80 in which the 2 nd guide long hole 83 is formed.

The seat S of the vehicle on which the child seat 10 is mounted has raised portions SA on both sides of the seat surface. The raised portions SA support the buttocks of the occupant seated in the seat S from both sides, and increase the stability of the occupant in the width direction DY, thereby improving the comfort. On the other hand, as shown in fig. 6, the raised portion SA covers the lower portion of the support base 20 from the side.

In the child seat of the related art, an operation switch for operating the link has: a housing fixed to the child seat main body; and a connection releasing member which is movably supported by the housing. Then, the portion exposed from the housing of the coupling releasing member is operated with a finger. However, in the child seat of the related art, the coupling release member is only slightly exposed from the housing due to the covering of the protrusion SA, and therefore, there is a problem that the operation is very difficult.

In this regard, in the illustrated child seat 10, the coupling release member 70 protrudes forward from the child seat body 11 at a position forward of the coupling 60. Therefore, the child seat body 11 can be made to function as a housing of the coupling/decoupling member 70, and the necessity of providing a housing for movably supporting the coupling/decoupling member 70 in the child seat body 11 is eliminated. Therefore, the coupling/decoupling member 70 can be increased in size while suppressing an increase in size of the fixing unit 50, and thus the coupling/decoupling member 70 protruding from the child seat body 11 can be largely exposed from the child seat body 11 and the raised portion SA of the seat S. As a result, it is possible to easily place fingers on the coupling/decoupling member 70, easily grasp the coupling/decoupling member 70, and the like, and thus the operability of the coupling/decoupling member 70 can be greatly improved.

In the illustrated fixing unit 50, it is necessary to perform an operation of moving the coupling releasing member 70 to the front side while pressing the restriction releasing member 75 to the rear side. However, the restriction releasing member 75 includes a restriction releasing operation portion 76 that is exposed forward from the coupling releasing member 70. The coupling releasing member 70 has an operation surface 72a facing rearward. Therefore, the coupling release member 70 and the restriction release member 75 can be moved forward in the front-rear direction DX while the restriction release operation portion 76 and the operation surface 72a are gripped by one hand in the front-rear direction DX, and therefore, the operation can be performed easily.

In this way, the coupling release member 70 and the restriction release member 75 are moved to the front side in the front-rear direction DX. While the coupling release member 70 moves from the position (C) in fig. 14 to the position (D) in fig. 14, the intermediate transmission member 85 and the release operation member 65 also move in synchronization with the coupling release member 70. In particular, the release operation member 65 moves from the coupling position shown in fig. 12 to the release position shown in fig. 13. Accordingly, as shown in fig. 11, the coupling member 62 is rotated to the release position shown in fig. 11 by the biasing force from the coupling member biasing member 64, and the coupling between the coupling member 60 and the anchor a is released.

In the state of fig. 14 (C), the operation restricting member 79 is positioned at an intermediate portion in the front-rear direction DX in the 1 st elongated hole portion 56a of the restriction elongated hole 56 of the coupling releasing member 70. Therefore, the coupling release member 70 can be moved from the state (C) in fig. 14 to the front side in the front-rear direction DX with respect to the intermediate frame member 80 to the state (D) in fig. 14. In the state of fig. 14 (C), the operation restricting member 79 is positioned at an intermediate portion in the front-rear direction DX in the 3 rd hole portion 78C of the drive long hole 78 of the restriction releasing member 75. Therefore, the coupling release member 70 can be moved together with the restriction release member 75 from the state (C) in fig. 14 to the front side in the front-rear direction DX with respect to the intermediate frame member 80 to the state (D) in fig. 14.

In addition, the coupling 60 is generally miniaturized, and the operation amount of the release operation member 65 is also very small. Therefore, it is also conceivable that the state of the coupling 60 cannot be accurately grasped by operating the release operation member 65. That is, it is assumed that it is difficult to know whether or not the coupling of the coupling member 60 and the anchor a is released after the predetermined operation of the release operation member 65 is completed. In order to eliminate such a problem, it is conceivable to design the operation amount of the release operation member to be large, but there is a desire in the industry to continue to use the coupling with a certain use result rather than redesigning the coupling every time. In particular, in combination with the standardized ISOFIX type anchor a, the coupling 60 having many years of use is widely used, and it is advantageous to commonly use the coupling 60 from various viewpoints of reliability, safety, cost reduction, and the like.

In this regard, in the above-described fixing unit 50, the coupling releasing member 70 is indirectly connected to the releasing member 65 via the intermediate transmission member 85, and the releasing member 65 is relatively movable by a predetermined length in the moving direction when the coupling releasing member 70 is operated. Further, the 1 st biasing member 51 applies a biasing force to the coupling releasing member 70 in a direction opposite to the direction of movement when the coupling releasing member 70 is operated. Therefore, when the coupling releasing member 70 is operated, the coupling releasing member 70 is first moved relative to the intermediate transmission member 85 and the release operating member 65 against the biasing force. Then, after the coupling release member 70 moves by a certain length, the intermediate transmission member 85 and the release operation member 65 can move from the coupling position to the release position as the coupling release member 70 moves. That is, the movement length MDX (see fig. 14) of the coupling release member 70 when the coupling release member 70 is operated to release the coupling of the coupling member 60 and the anchor a can be made longer than the movement length MDY (see fig. 14) of the release operation member 65 from the coupling position shown in fig. 12 to the release position shown in fig. 13. Therefore, the operation amount of the coupling releasing member 70 can be sufficiently ensured without depending on the structure of the coupling 60. As a result, by operating the release operation member 65 via the coupling release member 70, it is possible to sense that the coupling between the coupling member 60 and the anchor a is released.

After the coupling of the coupling member 60 and the anchor a is released as described above, the operation of the coupling releasing member 70 and the restriction releasing member 75 is stopped, and the hand is removed from the coupling releasing member 70 and the restriction releasing member 75. The release operation member 65 moves to the rear side in the front-rear direction DX to the position shown in fig. 11. As shown in fig. 14 (E), the intermediate transmission member 85 also moves to the rear side in the front-rear direction DX as the release operation member 65 moves backward. Then, the coupling releasing member 70 is moved to the rear side in the front-rear direction DX by the biasing force from the 1 st biasing member 51 so as to approach the intermediate transmission member 85. Further, the restriction releasing member 75 is moved forward in the front-rear direction DX with respect to the coupling releasing member 70 by the biasing force from the 2 nd biasing member 52.

By operating the restriction releasing member 75 and the coupling releasing member 70 as described above, the coupling between the coupling member 60 and the anchor a can be released. On the other hand, to couple the coupler 60 and the anchor a, as already described with reference to fig. 11 to 13, the anchor a may be inserted into the notch 61a of the coupler a and pushed forward from the rear side in the front-rear direction DX toward the rear side in the notch 61 a.

In one embodiment described above, the child seat 10 has a child seat body 11 and a fixing unit 50, wherein the child seat body 11 is disposed on a seat S of a vehicle; the fixing unit 50 is held by the child seat body 11, and is coupled to a anchor a provided in the seat S of the vehicle to fix the child seat body 11 to the seat S. The fixing unit 50 has a link 60 and a link releasing member 70, wherein the link 60 is coupled to the anchor a at the rear of the child seat body 11; the coupling between the coupler 60 and the anchor a is released by operating the coupling release member 70 to move relative to the child seat body 11. In particular, in this embodiment, the coupling release member 70 is exposed from the child seat body 11 at a position forward of the coupling 60. Therefore, the child seat body 11 can be made to function as a housing of the coupling/decoupling member 70, and the necessity of providing a housing for movably supporting the coupling/decoupling member 70 in the child seat body 11 is eliminated. Therefore, by increasing the size of the coupling/decoupling member 70 while suppressing an increase in the size of the fixing unit 50, the coupling/decoupling member 70 protruding from the child seat body 11 can be largely exposed from the child seat body 11 and the raised portion SA of the seat. As a result, it is possible to easily place fingers on the coupling/decoupling member 70, easily grasp the coupling/decoupling member 70, and the like, and thus the operability of the coupling/decoupling member 70 can be greatly improved. Further, by disposing the coupling release member 70 at a position displaced forward from the coupling 60 in the front-rear direction, the transmission structure for transmitting the movement of the coupling release member 70 to the coupling 60 can be made compact and simple. Accordingly, the operability of the coupling releasing member 70 can be effectively improved while suppressing an increase in the size of the fixing unit 50 and the child seat 10.

In the example of the embodiment described above, the child seat body 11 holds the intermediate portion of the fixing unit 50 extending in the front-rear direction DX from the periphery. According to this specific example, the fixing unit 50 can be stably held by the child seat main body 11.

In the example of the above-described one embodiment, the child seat body 11 is provided with the holding hole 27, the fixing unit 50 is inserted into the holding hole 27, the link 60 is extended rearward from the holding hole 27, and the link releasing member 70 is extended forward from the holding hole 27. According to this specific example, the connection releasing member 70 can be stably held by the child seat body 11 so as to be movable relative to the child seat body 11.

In the specific example of the above-described one embodiment, the coupling release member 70 includes the coupling release body portion 71 and the coupling release operating portion 72, wherein the coupling release body portion 71 extends in the front-rear direction DX and is inserted into the holding hole 27 of the child seat body 11 at the rear; the coupling release operation portion 72 is located in front of the coupling release body portion 71 and bulges outward in the width direction. According to this specific example, the coupling releasing member 70 can be held so as to be largely exposed from the child seat body 11, and the coupling releasing member 70 can be operated with respect to the child seat body 11. Accordingly, it is possible to more easily place a finger on the coupling releasing member 70 or to more easily grasp the coupling releasing member 70, and the like, thereby further improving the operability of the coupling releasing member 70. Further, by the coupling release operation portion 72 pressing the raised portion SA of the seat S, an operation space for operating the coupling release member 70 can be secured between the child seat 10 and the raised portion SA of the seat a in the front-rear region of the coupling release operation portion 72. The coupling releasing member 70 can be stably operated by placing a finger in the operation space.

In the specific example of the above-described one embodiment, the coupling release member 70 is positioned in front of the coupling 60 in the front-rear direction DX, and the coupling release member 70 has the coupling release operation portion 72 that bulges outward in the width direction. According to this specific example, it is possible to more easily place a finger on the coupling releasing member 70 or to more easily grasp the coupling releasing member 70, and the like, and thus the operability of the coupling releasing member 70 can be further improved. Further, the coupling release operation portion 72 presses the raised portion SA of the seat S, and thereby an operation space for operating the coupling release member 70 can be secured between the child seat 10 and the raised portion SA of the seat S in the front-rear region of the coupling release operation portion 72. The coupling releasing member 70 can be stably operated by placing a finger in the operation space.

In the specific example of the above-described embodiment, the coupling release operation portion 72 includes the operation surface 72a that is expanded in the width direction DY and faces rearward in the front-rear direction DX, and the coupling of the coupling 60 and the anchor a is released by the coupling release member 70 moving forward in the front-rear direction DX. According to this specific example, the operation of the coupling releasing member 70 for releasing the coupling of the coupling member 60 and the anchor a can be easily performed.

In the specific example of the above-described one embodiment, the width of the coupling release operation portion 72 in the width direction increases from the front side to the rear side in the front-rear direction, and the coupling of the coupling 60 and the anchor a is released by the coupling release member 70 moving forward in the front-rear direction DX. According to this specific example, the operation of the coupling releasing member 70 for releasing the coupling of the coupling member 60 and the anchor a can be easily performed.

In the above-described specific example of the one embodiment, the fixing unit 50 further includes the intermediate frame member 80, the link 60 is connected to the intermediate frame member 80 from the rear, the link releasing member 70 is extended from the front of the intermediate frame member 80, and the front end of the intermediate frame member 80 is positioned inside the child seat main body 11. According to this specific example, the intermediate frame member 80 is used to hold the coupling/decoupling member 70 so as to be largely exposed from the child seat body 11, and the coupling/decoupling member 70 can be operated with respect to the child seat body 11.

In the specific example of the above-described embodiment, the fixing unit 50 linearly extends in the front-rear direction DX. According to this specific example, the fixing unit 50 can be made compact and simplified, and as a result, the child seat 10 can be made compact and simplified.

In one example of the above-described embodiment, the fixing unit 50 further includes a restriction releasing member 75, and the restriction of the operation when the connection releasing member 70 is operated is released by operating the restriction releasing member 75. According to this embodiment, in order to release the connection between the connector 60 and the anchor A, the releasing operation is performed using two

members

70 and 75. Therefore, it is possible to effectively avoid the unintentional release of the coupling between the coupling member 60 and the anchor a.

In the specific example of the above-described one embodiment, the fixing unit 50 further includes the movement restricting member 79, the movement restricting member 79 restricts the movement of the coupling releasing member 70, and the restriction releasing member 75 acts on the movement restricting member 79 by performing the movement. According to this embodiment, in order to release the connection between the connector 60 and the anchor A, the releasing operation is performed using two

members

In one specific example of the above-described embodiment, the restriction releasing member 75 is supported by the connection releasing member 70 so as to be movable. According to this specific example, the fixing unit 50 can be downsized. Further, the restriction releasing member 75 and the coupling releasing member 70 can be easily operated by one hand. This makes it possible to easily release the coupling between the coupling member 60 and the anchor a.

In one specific example of the above-described embodiment, the front end portion of the restriction releasing member 75 is exposed forward from the coupling releasing member 70. According to this specific example, the restriction releasing member 75 can be easily operated. In particular, when the restriction releasing member 75 is exposed at the coupling releasing operation portion 72 of the coupling releasing member 70 or in the vicinity of the coupling releasing operation portion 72, the restriction releasing member 75 and the coupling releasing member 70 can be easily operated by one hand.

In the specific example of the above-described one embodiment, the restriction releasing member 75 is operated in the direction opposite to the operation of the coupling releasing member 70 when the coupling between the coupling member 60 and the anchor a is released, and thereby the restriction on the operation of the coupling releasing member 70 is released. In other words, the restriction releasing member 75 is operated in the direction opposite to the direction of operation when the connection releasing member 70 is operated in the direction of operation when the connection releasing member 70 is operated, and thereby the restriction on the operation when the connection releasing member 70 is operated is released. Specifically, the restriction of the operation when the connection releasing member 70 is operated is released by the restriction releasing member 75 moving rearward in the front-rear direction DX. According to this specific example, unintentional release of the coupling between the coupling member 60 and the anchor a can be more effectively avoided.

In one embodiment described above, the child seat 10 has a child seat body 11 and a fixing unit 50, wherein the child seat body 11 is disposed on a seat S of a vehicle; the fixing unit 50 is held to the child seat main body 11. The fixing unit 50 has a link 60 and a link releasing member 70, wherein the link 60 is connected to a fastener a provided in the seat S to fix the child seat body 11 to the seat; the coupling of the coupling member 60 and the fastener a is released by operating the coupling release member 70. The link 60 has a link member 62 and a release operation member 65, wherein the link member 62 links the link 60 to the anchor a; the release operation member 65 is moved from the coupling position to the release position to release the coupling of the coupling member 60 and the anchor a by the coupling member 62.

In this embodiment, the coupling releasing member 70 is directly or indirectly connected to the releasing member 65 so as to be movable by a predetermined length relative to the releasing member 65 in a moving direction when the coupling releasing member 70 is operated. The direction of the biasing force applied to the coupling releasing member 70 is opposite to the direction of movement when the coupling releasing member 70 is operated. Therefore, when the coupling releasing member 70 is operated, the coupling releasing member 70 is first moved relative to the releasing operation member 65 against the biasing force. Then, after the coupling release member 70 has moved by a certain length, the release operation member 65 starts moving from the coupling position and moves to the release position in accordance with the movement of the coupling release member 70. Therefore, in this embodiment, the movement length MDX (see fig. 14) of the coupling release member 70 when the coupling release member 70 is operated to release the coupling of the coupling member 60 and the anchor a can be made longer than the movement length MDY (see fig. 14) of the release operation member 65 from the coupling position to the release position. Therefore, the amount of operation of the coupling release member 70 for operating the release operation member 65 can be sufficiently ensured regardless of the configuration of the coupling 60. As a result, it is possible to sense that the coupling of the coupling member 60 and the anchor a is released by the operation of the release operation member 65.

In the specific example of the one embodiment described above, the fixing unit 50 includes the intermediate transmission member 85 and the 1 st urging member 51, wherein the intermediate transmission member 85 is fixed to the release operation member 65, and transmits the operation of the coupling release member 70 to the release operation member 65; the 1 st biasing member 51 is provided between the coupling release member 70 and the intermediate transmission member 85. The coupling releasing member 70 is connected to the intermediate transmission member 85 so as to be movable by a predetermined length relative to the intermediate transmission member 85 in a moving direction when the coupling releasing member 70 is operated, and is biased by the 1 st biasing member 51 in a direction opposite to the moving direction when the coupling releasing member 70 is operated. In this specific example, after the coupling release member 70 moves by a certain length, the intermediate transmission member 85 can move in synchronization with the coupling release member 70. The release operation member 65 is movable in synchronization with the intermediate transmission member 85. According to this specific example, the operation amount of the coupling release member 70 for releasing the coupling between the coupling 60 and the anchor a can be sufficiently ensured regardless of the structure of the coupling 60. In particular, the coupling releasing member 70 can be disposed away from the releasing operation member 65 by passing through the intermediate transmission member 85. This can improve the operability of the coupling release member 70.

In the specific example of the above-described one embodiment, a long hole (3 rd guide long hole) 87 is provided in one of the coupling/decoupling member 70 and the intermediate transmission member 85, and the long hole 87 is provided along the moving direction when the coupling/decoupling member 70 is operated. The other of the coupling releasing member 70 and the intermediate transmission member 85 is provided with an insertion portion (No. 2 guide insertion portion) 73, and the insertion portion 73 is movably inserted into the long hole 87. The insertion portion (2 nd guide insertion portion) 73 is movable in the elongated hole 87 in the moving direction when the coupling releasing member 70 is operated. According to this specific example, the coupling/decoupling member 70 and the intermediate transmission member 85 can be relatively moved by a predetermined length with a simple configuration.

In the above-described specific example of the embodiment, the fixing unit 50 further includes the intermediate frame member 80, the link 60 is fixed to the intermediate frame member 80 from the rear, and the link releasing member 70 protrudes from the front of the intermediate frame member 80. The intermediate transmission member 85 is movably supported by the intermediate frame member 80. A restriction long hole 56 is provided in one of the coupling release member 70 and the intermediate frame member 80, and the restriction long hole 56 has a 1 st long hole portion 56a and a 2 nd long hole portion 56b, wherein the 1 st long hole portion 56a extends in the moving direction when the coupling release member 70 is operated; the 2 nd long hole 56b extends in a direction orthogonal to the moving direction when the coupling releasing member 70 is operated, and is connected to the 1 st long hole 56 a. The movement restricting member 79 is movably inserted into the restriction long hole 56. The other of the coupling/decoupling member 70 and the intermediate frame member 80 supports the movement restricting member 79 so as to be movable in a direction orthogonal to the movement direction when the coupling/decoupling member 70 is operated. According to this specific example, the restriction of the operation of the coupling releasing member 70 and the switching of the restriction releasing can be realized by a simple operation using a simple configuration and a simple operation using the operation restricting member 79.

In the specific example of the above-described one embodiment, the operation restriction member 79 positioned in the 2 nd long hole portion 56b is moved to the 1 st long hole portion 56a by operating the restriction releasing member 75. According to this specific example, the restriction of the operation of the coupling releasing member 70 and the switching of the restriction releasing are realized by a simple operation using a simple configuration and a simple operation using the operation restricting member 79.

In one specific example of the above-described embodiment, the movement direction of the coupling releasing member 70 when the coupling releasing member 70 is operated to release the coupling of the coupling member 60 and the anchor a is parallel to the movement direction of the restriction releasing member 75 when the restriction releasing member 75 is operated to release the restriction on the movement of the coupling releasing member 70. In particular, the movement direction of the coupling release member 70 and the movement direction of the restriction release member 75 are along the front-rear direction. According to this specific example, it is possible to effectively avoid the unintentional release of the coupling between the coupling member 60 and the anchor a while effectively suppressing an increase in size of the fixing unit 50.

In the specific example of the above-described one embodiment, the direction of movement of the coupling releasing member 70 when the coupling releasing member 70 is operated to release the coupling of the coupling member 60 and the anchor a is opposite to the direction of movement of the restriction releasing member 75 when the restriction releasing member 75 is operated to release the restriction on the movement of the coupling releasing member 70. According to this specific example, it is possible to effectively avoid unintentional release of the coupling between the coupling member 60 and the anchor a while effectively suppressing an increase in size of the fixing unit 50.

In one example of the above-described embodiment, when the coupling release member 70 is operated to release the coupling of the coupling member 60 and the anchor a, the moving direction of the coupling release member 70 is parallel to the moving direction of the release operation member 65 from the coupling position to the release position. In particular, the movement direction of the coupling release member 70 and the movement direction of the release operation member 65 are along the front-rear direction. The coupling release member 70 and the release operation member 65 are moved in the same direction. According to this specific example, it is possible to easily detect that the connection between the fixing unit 50 and the vehicle anchor a is released while effectively suppressing an increase in size of the fixing unit 50.

First, the child seat body 11 can be variously modified. For example, although the above example shows an example in which the seat unit 30 is supported by the support base 20 so as to be adjustable in the backrest angle, the present invention is not limited to this example, and the seat unit 30 may be prevented from being adjustable in the backrest angle with respect to the support base 20.

The following steps can be also included: the coupling releasing member 70 is directly connected to the releasing operation member 65 so as to move a predetermined length relative to the releasing operation member 65 in a moving direction when the coupling releasing member 70 is operated, and is applied with a biasing force in a direction opposite to the moving direction when the coupling releasing member 70 is operated. That is, the connection releasing member 70 may be connected to the releasing operation member 65 without the intermediate transmission member 85.
