As is well shown in FIGS. 5 and 6, the first lock member holder 48a and the second lock member holder 48b extend in the front-rear direction of the seat 40, and other than the rotation axis Rx in the width direction of the seat 40. They are arranged on one side and one side apart from each other. As shown in FIGS. 1, 7 and 8, the upper surfaces of the first lock member holder 48a and the second lock member holder 48b form a part of the upper surface of the seat portion 43a of the seat 40.

Further, in the example shown in FIGS. 5 and 6, the lock member 47 has a third lock member 47c and a fourth lock member 47d. The third lock member 47c is held by the first lock member holder 48a, and the fourth lock member 47d is held by the second lock member holder 48b.

FIG. 9 is a view showing the first lock member holding body 48a shown in FIG. 7 from below. As shown in FIGS. 7 and 9, the first lock member 47a is held at the rear end portion of the first lock member holder 48a. Further, the third lock member 47c is held at the front end portion of the first lock member holder 48a. Therefore, the first lock member 47a and the third lock member 47c are arranged apart from each other in the front-rear direction.

Similarly, the second lock member 47b is held at the rear end portion of the second lock member holder 48b. Further, the fourth lock member 47d is held at the front end portion of the second lock member holder 48b. Therefore, the second lock member 47b and the fourth lock member 47d are arranged apart from each other in the front-rear direction.

The first lock member 47a and the second lock member 47b can move independently between the holding position shown in FIG. 10 and the releasing position shown in FIG. The first lock member 47a and the second lock member 47a move between the holding position and the releasing position by rotating around the rotation axes 47ax and 47bx extending in the width direction of the seat 40, respectively.

On the other hand, the third lock member 47c and the fourth lock member 47d cooperate with the first lock member 47a and the second lock member 47b, respectively, between the holding position shown in FIG. 10 and the release position shown in FIG. And move. That is, as shown in FIG. 10, when the first lock member 47a is arranged at the holding position, the third lock member 47c is also arranged at the holding position. Further, when the second lock member 47b is arranged at the holding position, the fourth lock member 47d is also arranged at the holding position. Further, as shown in FIG. 11, when the first lock member 47a is arranged at the release position, the third lock member 47c is also arranged at the release position. Further, when the second lock member 47b is arranged at the release position, the fourth lock member 47d is also arranged at the release position. The third lock member 47c and the fourth lock member 47d move between the holding position and the releasing position by rotating around the rotation axes 47cx and 47dx extending in the width direction of the seat 40, respectively.

Each lock member 47 is urged toward the release position by an urging means (not shown).

As shown in FIGS. 6 and 8, the seat 40 is provided with an operation member 50 and an operation transmission means 51 for moving the lock member 47 from the holding position to the release position. By being operated, the operation member 50 moves from the non-operation position shown by the solid line in FIG. 14 to the operation position shown by the two-dot chain line. The operation transmission means 51 moves the lock member 47 from the holding position to the release position as the operation member 50 moves from the non-operation position to the operation position.

In the illustrated example, as shown in FIG. 6, corresponding to the first lock member 47a and the second lock member 47b, the first operation member 50a and the first operation transmission means 51a, and the second operation member 50b and A second operation transmission means 51b is provided.

The first operating member 50a and the second operating member 50b can independently operate the first locking member 47a and the second locking member 47b, respectively. As can be understood from FIG. 6, the first operating member 50a and the second operating member 50b are provided at positions facing each other with the cushion member 42 supported by the seat frame 41 interposed therebetween. As a result, the user can operate the operating members 50a and 50b while stably holding the seat 40 from both sides of the cushion member 42. That is, it is easy to remove the seat 40 from the base 60 while operating the operating members 50a and 50b.

In the illustrated example, the first operating member 50a and the second operating member 50b are provided on one side and the other side in the width direction of the seat 40, respectively. More specifically, the first operating member 50a and the second operating member 50b are provided on the first gripping portion 45a and the second gripping portion 45b, respectively. In this case, it is easy to take out the seat 40 from the inside of the vehicle through the doorway of the vehicle in a state where the seat 40 is rotated to a position facing the side of the vehicle (a position facing the doorway of the vehicle). Here, in general, the dimension in the width direction of the seat 40 is smaller than the dimension in the front-rear direction of the seat 40. Therefore, if the seat 40 is rotated to a position facing the doorway of the vehicle, the seat 40 can be easily taken out even if the doorway of the vehicle is narrow.

The operating members 50a and 50b are not operated along a direction parallel to the relative movement direction (that is, the direction along the rotation axis Rx or the vertical direction) between the seat 40 and the base 60 when the seat 40 is removed from the base 60. Move from position to operation position. In the example shown in FIG. 14, the operating members 50a and 50b move upward from the non-operating position to the operating position. As described above, since the moving direction of the operating member 50 from the non-operating position to the operating position is along the relative moving direction, the operation of the operating member 50 and the operation of pulling out the seat 40 from the base 60 (the relative moving direction). It is easy to perform the operation (lifting along the line) as a series of operations. That is, the operation of removing the seat 40 from the base 60 becomes simple.

As shown in FIG. 6, the first operation transmission means 51a is provided between the first operation member 50a and the first lock member 47a, and transmits the operation of the first operation member 50a to the first lock member 47a. Further, the second operation transmission means 51b is provided between the second operation member 50b and the second lock member 47b, and transmits the operation of the second operation member 50b to the second lock member 47b.

As shown in FIG. 10, the first operation transmission means 51a includes a first extrusion mechanism 52a that pushes the lower end portions 47p of the first lock member 47a and the third lock member 47c to hold the lock members 47a and 47c in the holding position. , A first connecting means 53a for connecting the first extrusion mechanism 52a and the first operating member 50a. Similarly, the second operation transmitting means 51b has a second extrusion mechanism 52b that pushes the lower end portions 47p of the second lock member 47b and the fourth lock member 47d to hold the lock members 47b and 47d in the holding position, and a second extrusion. It includes a second connecting means 53b for connecting the mechanism 52b and the second operating member 50b.

As shown in FIG. 9, the first extrusion mechanism 52a is held by the first lock member holder 48a between the first lock member 47a and the third lock member 47c. As shown in FIGS. 10 and 11, the first extrusion mechanism 52a includes a first rear extrusion member 54a arranged in front of the lower end portion 47p of the first lock member 47a facing the lower end portion 47p, and a third rear extrusion member 54a. It has a first forward extrusion member 54c arranged behind the lower end portion of the lock member 47c so as to face the lower end portion. The first rear extrusion member 54a rotates around a rotation axis 54ax extending in the width direction of the seat 40, and pushes the first lock member 47a rearward to hold the first lock member 47a in the holding position (see FIG. 10). It moves between a non-extruded position (see FIG. 11) that allows the locking member 47a to move to the released position. Further, the first front extrusion member 54c rotates around the rotation axis 54cx extending in the width direction of the seat 40, and pushes the third lock member 47c forward to hold the third lock member 47c in the holding position (see FIG. 10). It moves between a non-extruded position (see FIG. 11) that allows the third locking member 47c to move to the release position.

Similarly, the second extrusion mechanism 52b is held by the second lock member holder 48b between the second lock member 47b and the third lock member 47d. As shown in FIGS. 10 and 11, the second extrusion mechanism 52b includes a second rear extrusion member 54b arranged in front of the lower end portion 47p of the second lock member 47b so as to face the lower end portion 47p, and a fourth. It has a second front extrusion member 54d arranged behind the lower end portion 47p of the lock member 47d so as to face the lower end portion 47p. The second rear extrusion member 54b rotates around a rotation axis 54bx extending in the width direction of the seat 40, and pushes the second lock member 47b rearward to hold the second lock member 47b in the holding position (see FIG. 10) and a second. It moves between a non-extruded position (see FIG. 11) that allows the locking member 47b to move to the released position. Further, the second front extrusion member 54d rotates around the rotation axis 54dx extending in the width direction of the seat 40, and pushes the fourth lock member 47d forward to hold the fourth lock member 47d in the holding position (see FIG. 10). It moves between a non-extruded position (see FIG. 11) that allows the fourth locking member 47d to move to the open position.

Further, the extrusion mechanisms 52a and 52b are arranged between the rear extrusion members 54a and 54b and the front extrusion members 54c and 54d, and the rear extrusion members 54a and 54b and the front extrusion members 54c and 54d are extruded and non-extruded positions. It has a link mechanism 55 for moving to and from. As shown in FIGS. 10 to 13, the link mechanism 55 has a rear link member 56a, a front link member 56b, and a central link member 56c arranged between the rear link member 56a and the front link member 56b. .. The lower ends of the corresponding rear extrusion members 54a and 54b are connected to the rear end of the rear link member 56a. Further, the lower ends of the corresponding front extrusion members 54c and 54d are connected to the front end of the front link member 56b. Further, the front end of the rear link member 56a is connected to one end of the central link member 56c, and the rear end of the front link member 56b is connected to the other end. The central link member 56c is rotatable around a rotation axis 56cx extending in the vertical direction between both ends thereof. Further, one end 53ap, 53bp of the corresponding connecting means 53a, 53b is connected to the other end of the central link member 56c. Then, when the other end of the central link member 56c is pulled backward by the connecting means 53a and 53b, the central link member 56c rotates around the rotation axis 56cx and pulls the rear link member 56a forward at the same time as the front link member. 56b is pulled backward. The rear link member 56a is pulled forward, and the front link member 56b is pulled backward, so that the rear extrusion members 54a and 54b and the front extrusion members 54c and 54d move to non-extruded positions.

The first central link member 56c is urged toward a position (position shown in FIG. 12) in which the first rear link member 56a is pushed backward and the front link member 56b is pushed forward by an urging means (not shown). ing. Therefore, the link mechanism 55 holds the rear extrusion members 54a, 54b and the front extrusion members 54c, 54d in the extrusion position when the other end of the central link member 56c is not pulled backward by the connecting means 53a, 53b. .. As a result, the corresponding lock member 47 is held at the holding position shown in FIG.

Further, as described above, each lock member 47 is urged to the release position by an urging means (not shown). Therefore, when the other end of the central link member 56c is pulled backward by the connecting means 53a, 53b and the rear extrusion members 54a, 54b and the front extrusion members 54c, 54d move to non-extruded positions, the corresponding lock member 47 , Move to the release position.

The connecting means 53a and 53b are wire rods. As described above, and as shown in FIGS. 6 and 10, one end 53ap, 53bp of each of the connecting means 53a, 53b is connected to the central link member 56c of the corresponding link mechanism 55. Further, as shown in FIGS. 6 and 14, the other end portions 53aq and 53aq of the respective connecting means 53a and 53b are connected to the corresponding operating members 50a and 50b.

As shown in FIG. 6, one end 53ap, 53bp of each of the connecting means 53a, 53b extends rearward from the central link member 56c in the seat portion 43a of the seat 40. Further, as can be understood from FIG. 14, the other end portions 53aq and 53aq of the connecting means 53a and 53b extend in the vertical direction in the first side portion 44a and the second side portion 44b of the seat 40.

Therefore, when the first operation member 50a and the second operation member 50b are operated to move upward from the non-operation position to the operation position, the other ends 51aq and 51bq of the corresponding operation transmission means 51 are pulled upward. And one end 51ap, 51bp is pulled backwards. As a result, the corresponding central link member 56c rotates, and the extrusion members 54a, 54b, 54c, 54d of the extrusion mechanisms 52a, 52b move to the non-extruded position. As a result, the corresponding lock member 47 moves to the release position.

By providing two sets of lock members 47 and operation members 50 that are operated independently of each other (in the illustrated example, the lock members 47a, 47c and the operation member 50a, and the lock members 47b, 47d) are provided. And by providing the operating member 50b), it is possible to more effectively prevent the seat 40 from being unintentionally disengaged from the base 60. This is because only when both the first operating member 50a and the second operating member 50b are operated at the same time, both the locking members 47a and 47c and the locking members 47b and 47d move to the non-holding position and from the base 60 of the seat 40. This is because the removal of the is allowed.

As shown in FIGS. 5 and 6, a rotation restricting convex portion 58 is provided on the bottom surface of the cylindrical connecting convex portion 46. The rotation restricting convex portion 58 is movable between a protruding position in which a part thereof protrudes downward from the bottom surface of the connecting convex portion 46 and an accommodating position in which all of them are accommodated in the connecting convex portion 46. Then, the rotation-regulating convex portion 58 moves from the protruding position to the accommodation position by operating the rotation-regulating convex portion operating means 57 provided on the seat 40. The rotation of the seat 40 with respect to the base 60 is restricted by accommodating the rotation regulation convex portion 58 in the protruding position in the rotation regulation recess 89 of the base 60 described later. The rotation restricting convex portion 58 is urged to a protruding position by an urging means (not shown). Therefore, when the rotation restricting convex portion operating means 57 is not operated, the rotation restricting convex portion 58 is arranged at the protruding position.

Next, the base 60 will be described with reference to FIGS. 7, 8 and 15 to 18. FIG. 15 is a perspective view showing the base 60 supported by the pedestal 20. Further, FIG. 16 is a diagram showing the base 60 shown in FIG. 12 in an exploded manner. Further, FIG. 17 is a diagram showing a leg portion 62a and an engaging portion 70, which will be described later, of the base 60 supported by the pedestal 20. In FIG. 17, a part of the pedestal 20 is cut out for the sake of clarification. Further, the illustration of one of the pair of legs 62a and 62b of the base 60, 62b, is omitted. Further, FIG. 18 is a top view of the child seat 10.

As shown in FIGS. 15 and 16, the base 60 includes a base body 61, a cover member 80 that covers the base 21 of the pedestal 20 together with the base body 61 from above, and an annular rotation guide arranged on the cover member 80. It has a member 85 and.

As shown in FIG. 16, the base body 61 includes a pair of legs 62a, 62b, an engaging portion 70 for engaging the pair of legs 62a, 62b with the base 21 of the pedestal 20, and an engaging portion 70. It has an operation unit 75 to be operated.

The pair of legs 62a and 62b extend in the front-rear direction of the base 60 below the cover member 80, and are arranged apart from each other in the width direction. The pair of legs 62a and 62b are in sliding contact with the base 21 of the cradle 20.

The pair of legs 62a and 62b are connected by a connecting portion 73. The connecting portion 73 includes a main connecting portion 73a that connects the central portions of the legs 62a and 62b in the front-rear direction, a front end connecting shaft 73b that connects the front ends of the legs 62a and 62b, and the legs 62a and 62b. It has a rear end connecting shaft 73c, which connects the rear ends.

As is well shown in FIG. 17, the engaging portion 70 includes an engaging shaft 71 that extends in the width direction of the base 60 and engages with the base 21 of the pedestal 20, and a support portion that supports the engaging shaft 71. 72 and.

The support portion 72 is supported by the main connecting portion 73a between the pair of leg portions 62a and 62b. The support portion 72 is rotatably supported around a rotation axis 72x extending in the width direction of the base 60. The support portion 72 has an upper end portion 72m located above the rotation axis 72x and a rear end portion 72n located behind the rotation axis 72x. An operation unit 75 is connected to the upper end portion 72m of the support portion 72. Further, the rear end portion 72n of the support portion 72 is provided with an insertion hole 72h. An engaging shaft 71 is inserted through the insertion hole 72h. By operating the operation unit 75 and pulling the upper end portion 72m of the support portion 72 forward, the support portion 72 rotates around the rotation axis 72x, and the rear end portion 72n of the support portion 72 together with the engagement shaft 71. Move upwards. The support portion 72 is urged by an urging means (not shown), and when the operation of the operating portion 75 is stopped, the rear end portion 72n moves downward together with the engaging shaft 71.

The engaging shaft 71 extends in the width direction of the base 60 and engages with the ridge portion 31, which will be described later. Specifically, it is housed in the groove 32 of the ridge portion 31. As described above, the engaging shaft 71 moves in the vertical direction as the support portion 72 rotates. As the engaging shaft 71 moves upward, it comes out of the groove 32 of the ridge portion 31.

Both ends of the engaging shaft 71 are housed in the engaging shaft accommodating holes 62h provided on the side surfaces of the legs 62a and 62b facing each other. As is well shown in FIG. 7, the engaging shaft accommodating hole 62h extends in the vertical direction so as not to hinder the vertical movement of the engaging shaft 71. On the other hand, since the engaging shaft 71 is accommodated in the engaging shaft accommodating hole 62h, the movement of the engaging shaft 71 with respect to the legs 62a and 62b in the front-rear direction is restricted. Therefore, when the engaging shaft 71 moves in the front-rear direction, the legs 62a and 62b also move in the front-rear direction.

The operation unit 75 includes a pull tab portion 76, and a connecting means 77 for connecting the pull tab portion 76 and the support portion 72. By pulling the pull tab portion 76 forward, the upper end portion 72 m of the support portion 72 is pulled forward, and the support portion 72 rotates around the rotation axis 72x. Then, the rear end portion 72n of the support portion 72 rises together with the engaging shaft 71. Further, by further pulling the pull tab portion 76, the engaging shaft 71 and the pair of leg portions 62a and 62b move forward together with the support portion 72.

As shown in FIGS. 15 and 16, the cover member 80 has a bottom surface 80s that is curved downward. As shown in FIGS. 7 and 8, the bottom surface 80s forms a connection recess 81 for accommodating the connection protrusion 46 of the seat 40 together with the rotation guide member 85 described later. Further, in front of the bottom surface 80s, a puller portion through hole 83 for exposing a part of the puller portion 76 of the operation portion 75 is provided. The cover member 80 is fixed to the pair of legs 62a and 62b.

As shown in FIGS. 15 and 16, the bottom surface 80s of the cover member 80 is formed with a rotation-regulating recess 89 for accommodating the rotation-regulating convex portion 58 of the seat 40. By accommodating the rotation restricting convex portion 58 in the rotation restricting concave portion 89, the rotation of the seat 40 with respect to the base 60 is restricted. In the illustrated example, the cover member 80 has a front rotation restricting recess 89f formed in the front region of the bottom surface 80s, a rear rotation restricting recess 89r formed in the rear region of the bottom surface 80s, and a base 60 in the width direction. It has two lateral rotation restricting recesses 89a and 89b formed in both side regions of the bottom surface 80s, respectively.

When the rotation restricting convex portion 58 of the seat 40 is housed in the front rotation restricting recess 89f, the seat 40 is in a forward facing state. Further, when the rotation restricting convex portion 58 of the seat 40 is housed in the rear rotation restricting recess 89r, the seat 40 is in the rearward facing state. Further, when the rotation restricting convex portion 58 of the seat 40 is housed in the lateral rotation restricting recesses 89a and 89b, the seat 40 faces one side or the other side in the width direction of the base 60 (in FIG. 18, respectively). The state shown by the solid line and the alternate long and short dash line).

As shown in FIGS. 15 and 16, the rotation guide member 85 has an annular shape. The connecting convex portion 81 of the seat 40 is arranged inside the annular rotation guiding member 85. The rotation guide member 85 supports the seat 40 from below around the connecting protrusion 81. Therefore, when the seat 40 rotates with respect to the base 60, the seat 40 and the rotation guiding member 85 slide with respect to each other. In the illustrated example, the rotation guide member 85 has a cylindrical shape with the rotation axis Rx as the center line as a whole. This stabilizes the rotation of the seat 40. The rotation guide member 85 is fixed to the cover member 80.

As shown in FIGS. 7 and 8, a regulating portion 86 extending inward in the radial direction about the rotation axis Rx extends from the upper end portion of the rotation guiding member 85. The restricting unit 86 is provided at a position where the rotation guide member 85 overlaps with the lock member 47 at the holding position in the projection in the moving direction when the seat 40 is removed from the base 60, and is displaced from the lock member 47 at the release position. Has been done. The contact (interference) between the restricting portion 86 and the lock member 47 located at the holding position restricts the removal of the seat 40 from the base 60.

Specifically, as is well shown in FIG. 7, when the lock member 47 is positioned at the holding position, the lower end portion 47p of the lock member 47 comes into contact with the regulation portion 86 of the rotation guide member 85 from below to seat. The removal of the 40 from the base 60 is restricted. Further, when the lock member 47 is located at the released position, the lower end portion 47p of the lock member 47 is separated from the restricting portion 86, and the seat 40 is allowed to be removed from the base 60.

In the illustrated example, the regulating portion 86 is formed in an annular shape, particularly in a circular shape, along the upper end portion of the annular shape of the rotation guiding member 85. As a result, regardless of the rotation position of the seat 40 with respect to the base 60, the removal of the seat 40 from the base 60 is restricted by the contact (interference) between the restricting portion 86 and the lock member 47 located at the holding position. To. On the other hand, the seat 40 can be removed from the base 60 by separating the lock member 47 from the regulating portion 86 regardless of the rotational position of the seat 40 with respect to the base 60.

Next, with reference to FIG. 17, the base 21 of the cradle 20 will be described in detail. The base portion 21 has a base body 23a and a cover member 23b that covers the base body 23a. The base body 23a has a regulating portion 30 that regulates the sliding of the base 60 with respect to the pedestal 20. The regulating portion 30 is provided at the center in the width direction of the base main body 23a. The regulating portion 30 includes a ridge portion 31 extending in the front-rear direction. The ridge portion 31 is provided with a groove 32 that can receive the engaging shaft 71 extending in the width direction of the pedestal 20 from above. A plurality of grooves 32 are provided apart from each other in the front-rear direction. Thereby, the inclination of the base 60 with respect to the pedestal 20 can be adjusted in a plurality of steps.

An opening 24 for exposing the regulating portion 30 is provided at the center of the cover member 23b in the width direction. As a result, the ridge portion 31 of the regulating portion 30 can be engaged with the engaging shaft 71 of the base 60.

At a position in front of the restricting portion 30, a front guiding portion 26 for guiding the front end portion of the base 60 is formed between the cover member 23b and the base main body 23a. More specifically, the opening peripheral surface 24s that defines the opening 24 of the cover member 23b is provided with a notch 27 at a position in front of the restricting portion 30. The front end connecting shaft 73b of the base 60 is inserted through the notch 27. As is well shown in FIG. 7, the notch 27 extends in the anteroposterior direction and is inclined upward toward the front. As a result, as the base 60 moves forward, the front end portion of the base 60 moves upward (see FIG. 2).

Further, behind the regulating portion 30, a rear guiding portion (not shown) for guiding the rear end portion (specifically, the rear end connecting shaft 73c) of the base 60 is provided. The rear guide portion guides the base 60 so that the rear end portion of the base 60 moves downward as the base 60 moves forward (see FIG. 2).

As described above, as the base 60 moves forward with respect to the pedestal 20, the rear end portion of the base 60 moves downward and the front end portion of the base 60 moves upward (see FIG. 2). Therefore, by moving the base 60 in the front-rear direction with respect to the pedestal 20, the inclination of the base 60 with respect to the pedestal 20 changes.

Next, with reference to FIGS. 2 and 17, the operation of the child seat 10 having the above configuration in the reclining operation will be described.

A case where the seat 40 is reclined from the position shown by the solid line in FIG. 2 will be described. First, as shown in FIG. 17, the engaging shaft 71 of the base 60 is housed in a groove 32 located at the rearmost position of the ridge portion 31 provided at the base 21 of the pedestal 20. As a result, the base 60 is restricted from moving in the front-rear direction with respect to the pedestal 20 at the position shown by the solid line in FIG.

In this state, when the puller portion 76 of the operation portion 75 is pulled forward, the support portion 72 rotates and the engaging shaft 71 moves upward and exits from the groove 32. Then, when the puller portion 76 is further pulled forward, the engaging shaft 71 and the pair of leg portions 62a and 62b move forward together with the support portion 72. As a result, the seat 40 supported by the base 60 moves forward together with the base 60. At this time, the base 60 is guided by the front guide portion 26 and the rear guide portion of the pedestal 20, so that the base 60 tilts with respect to the pedestal 20 together with the seat 40. When the inclination of the seat 40 with respect to the pedestal 20 becomes a desired inclination, the operation of the operation unit 75 is terminated. As a result, the support portion 72 rotates and the engaging shaft 71 moves downward. Then, the engaging shaft 71 is housed in the groove 32 of the ridge portion 31. As a result, the movement of the base 60 and the seat 40 with respect to the pedestal 20 in the front-rear direction is restricted while the base 60 and the seat 40 are tilted with respect to the pedestal 20.

On the other hand, in order to erect the seat 40 tilted with respect to the pedestal 20, the following operation may be performed. That is, the puller portion 76 of the operation portion 75 is pulled forward to rotate the support portion 72. As a result, the engaging shaft 71 moves upward and exits from the groove 32. In this state, the base 60 is pushed backward to move with the seat 40. At this time, the base 60 is guided by the front guide portion 26 and the rear guide portion of the pedestal 20, so that the base 60 stands up with respect to the pedestal 20 together with the seat 40. When the inclination of the seat 40 with respect to the pedestal 20 becomes a desired inclination, the operation of the operation unit 75 is terminated. As a result, the support portion 72 rotates and the engaging shaft 71 moves downward. Then, the engaging shaft 71 is housed in the groove 32 of the ridge portion 31. As a result, the movement of the base 60 and the seat 40 in the front-rear direction with respect to the pedestal 20 is restricted while the base 60 and the seat 40 stand upright with respect to the pedestal 20.

Next, with reference to FIG. 3, the action of the seat 40 on the pedestal 20 in the rotation operation will be described.

A case where the seat 40 is changed from the front facing state to the rear facing state will be described. First, the rotation-regulating convex portion 58 of the seat 40 is housed in the front rotation-regulating recess 89f of the base 60. This restricts the rotation of the seat 40 with respect to the base 60 and the pedestal 20.

In order to rotate the seat 40, the rotation restricting convex portion operating means 57 is operated to pull up the rotation restricting convex portion 58 upward. As a result, the rotation restricting convex portion 58 escapes from the front rotation restricting concave portion 89f. Then, the seat 40 is rotated with respect to the base 60 around the rotation axis Rx.

When the seat 40 is in the backward facing state, the operation of the rotation restricting convex portion operating means 57 is terminated. As a result, the rotation restricting convex portion 58 moves downward and is accommodated in the rear rotation restricting recess 89r. As a result, the rotation of the seat 40 with respect to the base 60 and the pedestal 20 is restricted.

In order to change the seat 40 from the backward facing state to the forward facing state, or the state shown by the solid line or the alternate long and short dash line in FIG. 18, the same operation as the above-mentioned rotation operation may be performed.

Next, with reference to FIGS. 10, 11 and 14, the operation of the seat 40 on the pedestal 20 in the removal operation will be described.

First, the lock member 47 is arranged at the holding position, and the lower end portion 47p thereof is in contact with the regulation portion 86 of the rotation guide member 85 from below. This restricts the removal of the seat 40 from the base 60.

In order to remove the seat 40 from the cradle 20, the operating member 50 is moved from the non-operating position shown in FIG. 14 to the operating position. As a result, the link mechanism 55 of the extrusion mechanism 52 is operated to move the extrusion members 54a, 54b, 54c, 54d from the extrusion position (see FIG. 10) to the non-extrusion position (see FIG. 11). Then, the lock member 47 is moved to the release position (see FIG. 11) by an urging means (not shown). At this time, the lower end portion 47p of the lock member 47, which has been in contact with the regulation portion 86 of the rotation guide member 85 from below, is separated from the regulation portion 86. As a result, the seat 40 becomes removable from the base 60 and the cradle 20. Then, with the lock member 47 arranged at the released position, the seat 40 is pulled out from the base 60 along the extending direction of the rotation axis Rx.

In order to attach the seat 40 to the base 60, the operation reverse to the above-mentioned removal operation may be performed.

In the above-mentioned example, the case where the seat 40 has the lock member 47 and the base 60 has the regulation portion 86 has been described, but the present invention is not limited to this. For example, the base 60 may have a locking member 47 and the seat 40 may have a regulating portion 86. In this case, the contact (interference) between the lock member 47 and the seat 40 restricts the removal of the seat 40 from the base 60. When the base 60 has the lock member 47 and the seat 40 has the regulation portion 86, the operation member 50 may be provided on the base 60.

Further, in the above-mentioned example, the case where the first operating member 50a and the second operating member 50b are provided on one side and the other side in the width direction of the seat 40 has been described, but the present invention is not limited to this. The first operating member 50a and the second operating member 50b may be provided, for example, on one side and the other side in the front-rear direction of the seat 40.

Further, in the above-mentioned example, the first lock member 47a and the second lock member 47b are separated from each other in the width direction of the seat 40, and the third lock member 47c and the fourth lock member 47d are the first lock member 47a and the second lock member 47a and the second lock, respectively. Although the case where the member 47b is separated from the member 47b in the front-rear direction has been described, the present invention is not limited to this. The third lock member 47c and the fourth lock member 47d may be separated from the first lock member 47a and the second lock member 47b in any first direction, respectively, and the first lock member 47a and the third lock member 47a and the third lock member 47d may be separated from each other in an arbitrary first direction. The member 47c may be separated from one and the other of the second lock member 47b and the fourth lock member 47d in the second direction intersecting the first direction, respectively. Also in this case, since the swing of the seat 40 in the first direction and the second direction intersecting each other is restricted by the contact between the lock member 47 and the rotation guide member 85, the seat 40 is stably held on the base 60. Can be done.

As described above, according to the present embodiment, the child seat 10 is supported by the pedestal 20, the base 60 supported by the pedestal 20 so as to be tiltable, and the base 60 rotatably and removablely. It is equipped with a seat 40. One of the base 60 and the seat 40 has an annular rotation guiding member 85 that slides with respect to the other of the base 60 and the seat 40 when the seat 40 and the base 60 rotate relative to each other. Further, the other of the base 60 and the seat 40 has a lock member 47 that can move between the holding position and the releasing position. Then, when the lock member 47 is positioned at the holding position, the lock member 47 comes into contact with the rotation guide member 85 to restrict the removal of the seat 40 from the base 60. Further, when the lock member 47 is located at the released position, the lock member 47 is separated from the rotation guide member 85 and the seat 40 is allowed to be removed from the base 60. With such a child seat 10, the seat 40 can be reclined and rotated with respect to the pedestal 20 and can be removed from the base 60 and the pedestal 20.

In this embodiment, the seat 40 is removable from the base 60 at any relative rotation position with respect to the base 60. Thereby, the user can remove the seat 40 from the base 60 from any direction with respect to the child seat 10.

Specifically, the rotation guide member 85 is provided at a position that overlaps with the lock member 47 at the holding position and deviates from the lock member 47 at the release position in the projection in the moving direction when the seat 40 is removed from the base 60. It has a regulation unit 86. Then, the regulation portion 86 and the lock member 47 located at the holding position restrict the removal of the seat 40 from the base 60.

Further, in the present embodiment, the lock member 47 has a first lock member 47a and a second lock member 47b that can be moved independently. Further, one of the base 60 and the seat 40 is provided between the first operation member 50a and the second operation member 50b that can be operated independently, and the first operation member 50a and the first lock member 47a, and the first operation is performed. The operation of the second operation member 50b provided between the first operation transmission means 51a for transmitting the operation of the member 50a to the first lock member 47a and the second operation member 50b and the second lock member 47b is performed by the second lock member. It has a second operation transmission means 51b for transmitting to 47b. As a result, the seat 40 can be removed from the base 60 only when both the first operating member 50a and the second operating member 50b are operated. Therefore, it is effectively prevented that the seat 40 is unintentionally disengaged from the base 60.

Further, in the present embodiment, the lock member 47 further includes a third lock member 47c that can move between the holding position and the release position in cooperation with the first lock member 47a, and the second lock member 47b. It has a fourth locking member 47d that can move between the holding position and the releasing position in cooperation with each other. The third lock member 47c and the fourth lock member 47d are separated from the first lock member 47a and the second lock member 47b in the first direction, respectively. Further, the first lock member 47a and the third lock member 47c are separated from one and the other of the second lock member 47b and the fourth lock member 47d, respectively, in the second direction intersecting the first direction. As a result, the swing of the seat 40 in the first direction and the second direction intersecting each other is restricted by the contact between the lock member 47 and the rotation guide member 85. As a result, the seat 40 can be stably held on the base 60.

Further, in the present embodiment, the seat 40 is positioned so as to face the seat frame 41 supported by the base 60, the cushion member 42 supported by the seat frame 41, and the cushion member 42 of the seat frame 41 in between. The first operating member 50a and the second operating member 50b provided in the above are provided. As a result, the user can operate the operating members 50a and 50b while stably holding the seat 40 from both sides of the cushion member 42. That is, the seat 40 can be removed from the base 60 while operating the operating members 50a and 50b.

Specifically, the seat 40 has a seat frame 41 having a seat portion 43a, a back portion 43b, and a first side portion 44a and a second side portion 44b provided so as to face each other and supported by a base 60, and a seat. It has a first operating member 50a provided on the first side portion 44a of the frame 41 and a second operating member 50b provided on the second side portion 44b of the seat frame 41. In this case, it is easy to take out the seat 40 from the outside of the vehicle through the doorway in a state where the seat 40 is rotated to a position facing the doorway of the vehicle. Here, in general, the dimension in the width direction of the seat 40 is smaller than the dimension in the front-rear direction of the seat 40. Therefore, if the seat 40 is rotated to a position facing the entrance / exit of the vehicle, the seat 40 can be easily taken out from the inside of the vehicle even if the entrance / exit of the vehicle is narrow.

Further, in the present embodiment, one of the base 60 and the seat 40 is moved from the non-operation position to the operation position by being operated, and the operation member 50 is moved from the non-operation position to the operation position. Accordingly, it has an operation transmitting means 51 for moving the lock member 47 from the holding position to the releasing position. Then, the operating member 50 moves from the non-operating position to the operating position along the relative moving direction between the seat 40 and the base 60 when the seat 40 is removed from the base 60. In this case, it is easy to perform the operation of the operating member 50 and the operation of pulling the seat 40 away from the base 60 (the operation of lifting along the relative moving direction) as a series of operations. That is, the operation of removing the seat 40 from the base 60 becomes simple.

Further, the child seat 10 of the present embodiment has a pedestal 20 and a seat 40 provided on the pedestal 20 whose inclination can be changed with respect to the pedestal 20, which is rotatable and separable. With such a child seat 10, the seat 40 can be reclined and rotated with respect to the pedestal 20 and can be removed from the pedestal 20.

Although some modifications to the above-described embodiments have been described above, it is naturally possible to apply a plurality of modifications in combination as appropriate.
