Description

[Technical Field]

[0001] The present invention relates to a child car seat in which the seat body is rotatable and reclining relative to a base. [Background technology]

[0002] A conventional child car seat is described in Patent Document 1, which includes a first fixing means for fixing the position of the seat body in the rotational direction and a second fixing means for fixing the position of the seat body in the sliding direction. Both the first fixing means and the second fixing means have an operating member for moving an engaging claw toward or away from the base or the rotating member, and the operating member of the first fixing means and the operating member of the second fixing means are arranged one above the other in the vertical direction on the bottom surface of the seat body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6093420 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above child car seat, the operating surface of the operating member of the second fastening means is located in a position that allows it to be pushed down from above, while the operating surface of the operating member of the first fastening means is located below the operating surface and can be pushed up from below, and because the operating directions are different for each, further improvements in operability were desired.

[0005] In view of the above, an object of the present invention is to provide a child car seat with improved operability. [Means for solving the problem]

[0006] According to the invention of claim 1, there is provided a child car seat comprising: a base attached to a vehicle seat; a seat body rotatable and reclining relative to the base; and a rotating member rotatable relative to the base, wherein the seat body is engaged and connected to the rotating member so as to be slidable relative to the rotating member, a mounting recess formed as a bottomed hole extending from the lower surface to the upper surface of the seat body is disposed on the lower surface side of the seat body; The rotary member has a locking hole formed therein, a first fixing means for fixing the position of the seat body relative to the base in a rotational direction, and a second fixing means for fixing the position of the seat body relative to the base in a sliding direction, the first fixing means includes a rotation operating member, the second fixing means includes a first sliding member and a second sliding member, the first slide operation member is formed in a U-shape and has a pair of side bars and a connecting post that connects the pair of side bars at one end, and has a locking piece that can be locked with the locking hole disposed at one end, and an engaging portion that can be engaged with the second slide operation member disposed at the other end, The second slide operation member is formed in a U-shape and has a pair of side bars and a connecting post that connects the pair of side bars at the other end side, and has an engaged portion that can engage with the engaging portion disposed at one end side, and an operation surface disposed at the other end side, the first slide operation member and the second slide operation member are pivotally supported in the mounting recess so that their rotation axes are parallel to each other; When the engaging portion and the engaged portion are engaged with each other and the second fixing means fixes the seat body, the engaging portion and the engaged portion are configured to be allowed to move only in a direction away from the seat body, the rotation operation member is rotatably supported at one end side relative to the first slide operation member, has an operation surface disposed at the other end side, has a rotation axis coaxial with the rotation axis of the first slide operation member, and has an engaging claw that can be engaged with an engaging groove disposed in the rotation member and the base, The surface of the other end of the rotation operating member opposite the seat body is capable of abutting against the surface of the other end of the second slide operating member facing the seat body, and the operating surfaces of the rotation operating member and the second slide operating member are pressed from the side away from the seat body.

[0007] According to this, when operating the operating surfaces of the rotation operation member and the second sliding operation member, the operating surfaces are pressed from the side away from the seat body, in other words, they can be operated from the same direction, improving operability. Furthermore, by configuring the second fixing means as being divided into the first sliding operation member and the second sliding operation member, the operating area of each member is reduced, making it possible to make the structure more compact.

[0008] The rotation operation member is disposed so that one end thereof is bridged between the side bars of the first slide operation member.

[0009] According to this, the strength of the first sliding operation member can be ensured by the rotation operation member.

[0010] Further, the fixed position of the seat body in the rotation direction can be released by operating the operation surface of the rotation operation member, By operating the operating surface of the second slide operating member, the rotation operating member and the second slide operating member come into contact, making it possible to release the fixed position of the seat body in the rotational direction and the fixed position of the seat body in the sliding direction.

[0011] This makes it possible to select and operate two modes: only releasing the fixation of the rotational position of the seat body, and releasing the fixation of the rotational position of the seat body and the sliding position of the seat body. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the present invention will be described below with reference to the drawings. In the following description, arrows in each drawing indicate F, B, R, L, U, and D, respectively.

[0014] In this embodiment, the state shown in FIG. 1 will be described as the original position.

[0015] As shown in FIGS. 1 to 3, the child car seat 10 of this embodiment includes a base 12 that is attached to a vehicle seat, and a seat body 14 that is rotatable and reclining relative to the base 12.

[0016] The seat body 14 has a shell portion 16 made of synthetic resin, and a cushioning material (not shown) made of foam is attached to the inside of this shell portion 16, and the outer surface sides of the shell portion 16 and the cushioning material are covered by a seat cover (not shown).

[0017] The seat body 14 is curved so as to cover the entire periphery of the seated infant except for the front and upper sides, and a shoulder belt and buckle (not shown) are arranged on the inside of the seat body 14 to secure the infant seated in the seat body 14.

[0018] The shell portion 16 is a one-piece molded product made of synthetic resin. In this embodiment, the shell portion 16 is made of polypropylene (PP) and includes a seat portion 18 that covers the underside and rear of the baby, side wall portions 20 that cover the left and right sides of the baby, and a back portion 22 that covers the back of the baby. A headrest 24 that can be adjusted in height in the vertical direction is attached to the back portion 22.

[0019] Reference numeral 13 denotes a pair of connectors protruding rearward from the lower back surface of the base 12. In the child car seat of this embodiment, the base 12 can be connected to the vehicle body (the vehicle seat side) by engaging hooks provided inside the connectors 13 with ISO-FIX type clamp bars provided on the vehicle seat side. The connectors 13 are provided rotatably with respect to the base 12, and can be stored inside the base 12 when not in use.

[0020] The child car seat 10 of this embodiment is also provided with a foldable support leg 15 on the bottom surface of the base 12. When the child car seat 10 is fixed to the vehicle seat, the support leg 15 can be raised in an L-shape on the vehicle floor, thereby preventing the child car seat 10 from rotating forward in the event of a frontal collision, etc., thereby improving the safety of the child car seat 10.

[0021] As shown in Figures 4, 6-7, etc., the seat portion 18 is formed with four slot-shaped openings 28, 29, 30, 31, which extend in the front-rear direction from near the front end toward the back portion 22, separated into right and left sides.

[0022] On both sides of the openings 28, 29, 30, 31 in the left-right direction in the drawing, protrusions 32, 33, 34, 35 are formed that extend continuously in the front-rear direction along the longitudinal edges of each opening.

[0023] 4 to 7, etc., a mounting recess 38, which is formed as a bottomed hole extending from the lower surface to the upper surface, is formed on the back side of the seating surface portion 18 of the seat main body 14. A first fixing means 140 and a second fixing means 80, which will be described later, are disposed in the mounting recess 38.

[0024] The rear side of the seating surface portion 18 , except for the mounting recess 38 and the openings 28 , 29 , 30 , 31 , forms a convex curved surface with a spherical radius facing the base 12 .

[0025] On the rear side of the mounting recess 38, two rear spring receiving portions 37 capable of fixing the spring 104 described later (omitted in Figures 6 and 7), and on the front side of the mounting recess 38, a front spring receiving portion 36 capable of receiving the spring 166 described later is provided. As shown in Figures 1, 2, 3, 5, etc., the base 12 can be divided into two parts in the vertical direction, and is composed of an upper base part 46 and a lower base part 47. These are each integrally molded from synthetic resin. As also shown in Figures 2 and 3, an annular support surface 26 is formed on the surface facing the bottom side of the seat main body 14 (the back side of the seating surface 18), and the support surface 26 abuts against the back side of the seating surface 18 of the seat main body 14 to support the seat main body 14. This support surface 26 is a concave curved surface, and the value of its spherical radius is the same as that of the convex curved surface on the seat main body 14 side. The seat main body 14 slides on the support surface 26 when rotating or sliding relative to the base 12.

[0026] Engagement grooves 48 for preventing rotational movement of the seat body 14 are formed at 90° intervals in the front-rear and left-right directions of the support surface 26. The grooves of these engagement grooves 48 arranged in the front-rear direction are long, and the grooves arranged in the left-right direction are short.

[0027] An upwardly facing circular opening is formed inside the support surface 26, and a rotary member 44 is rotatably housed inside the opening.

[0028] As shown in Figures 2 and 3, the rotating member 44 has a disk-like shape as a whole. Reference numeral 50 denotes a main surface portion that is circular in plan view and has an arc-shaped cross section. As shown in Figures 5, 12, and 13, the outer peripheral edge of the main surface portion 50 forms a peripheral wall portion 52 that extends downward and has a certain height. Furthermore, a flange portion 54 that extends outward is integrally formed at the lower end of the peripheral wall portion 52.

[0029] 2 and 3, four connecting protrusions 55, 56, 57, and 58 extending in the front-rear direction are formed on the upper surface of the main surface portion 50. These connecting protrusions have an oval outer shape in a plan view and have the same thickness in the short width direction. The thickness of the connecting protrusions is set slightly smaller than the width of the openings 28, 29, 30, and 31 of the seat main body 14 so that the connecting protrusions 55, 56, 57, and 58 can be inserted into the openings.

[0030] 2 and 3, the connecting protrusions 55 and 56 on the left side are arranged on the same line, and the connecting protrusions 57 and 58 on the right side are also arranged on the same line. The connecting protrusions 55, 56, 57, 58 are arranged in pairs on the same line, and as shown in FIG. 2, a guide rail 40 (described later) is attached to the upper surface of each pair.

[0031] Two male screws 59 are disposed on each of the connecting projections 55, 56, 57, and 58 so as to extend upward.

[0032] Furthermore, in the main surface portion 50, an engagement groove 60 that can be engaged with an engagement claw 158 of the first fixing means 140 (described later) is formed from the outer peripheral end toward the center.

[0033] Near the center of the rotating member 44, six through holes 62 (corresponding to locking holes in the claims) that can engage with locking pieces 96 of the second fixing means 80 (described later) are arranged side by side in the front-to-rear direction in the drawings (see FIGS. 2 and 3). The number of through holes 62 can be changed as needed.

[0034] This rotary member 44 is also integrally molded from synthetic resin.

[0035] The guide rail 40 has a generally U-shaped cross section as a whole. The guide rail 40 also has an arc-shaped longitudinal direction. The guide rail 40 is provided with eight holes 69 for inserting the male screws 59 for fixing, corresponding to the male screws 59.

[0036] Next, the connecting structure between the seat body 14 and the rotary member 44 will be described.

[0037] 2 and 3, in this embodiment, connecting protrusions 55, 56, 57, and 58 formed on the rotating member 44 are inserted into elongated hole-shaped openings 28, 29, 30, and 31 that extend in the front-rear direction and are formed in the seat main body 14. Therefore, when a force in the front-rear direction is applied to the seat main body 14, the seat main body 14 can slide in the front-rear direction based on the gaps that are generated between the elongated hole-shaped openings 28, 29, 30, and 31 and the connecting protrusions 55, 56, 57, and 58 in the front-rear direction.

[0038] Here, the bottom surface of the spherical seat body 14 is supported by the support surface 26 of the spherical base 12, and when the seat body 14 slides while being supported by the support surface 26, the tilt angle of the seat body 14 changes, thereby achieving a reclining function.

[0039] In this embodiment, the connecting protrusions 55, 56, 57, 58 come into contact with the opening ends of the slot-shaped openings 28, 29, 30, 31, thereby defining the movement limits of the seat body 14 in the front-rear direction.

[0040] When a rotational force acts on the seat body 14, the force acting on the seat body 14 is transmitted to the rotation member 44 by the engagement between the openings 28, 29, 30, 31 and the connecting protrusions 55, 56, 57, 58, and the seat body 14 rotates integrally with the rotation member 44, which is rotatably provided on the base 12. As a result, in this embodiment, the seat body 14 can be rotated around the central axis.

[0041] In addition, in this embodiment, with the connecting protrusions 55, 56, 57, 58 inserted into the openings 28, 29, 30, 31, respectively, and with the male screw 59 inserted into the hole 69, one guide rail 40 is positioned so as to cover from above the two connecting protrusions 55, 56 located on the same line and the linearly extending protrusions 32, 33 located on both sides of them, and this guide rail 40 is attached to the upper surfaces of the connecting protrusions 55, 56 with screw members.

[0042] Although the above description has been given of an example in which the guide rails 40 are attached to the connecting projections 55 and 56, the guide rails 40 can also be attached to the connecting projections 57 and 58 in the same manner.

[0043] 4, 6 and 7 are views showing the bottom side of the seat cushion portion 18 of the seat body 14. FIG.

[0044] Axial holes 72, 72 are formed at symmetrical positions on both left and right side wall surfaces 70, 71 of the mounting recess 38 formed on the bottom surface of the seat portion 18, and a first slide operating member 90 for fixing the position of the seat body 14 in the sliding direction is attached to the axial holes 72, 72 in a swingable manner.

[0045] In addition, axial holes 74, 74 are formed at positions on the rear side of the axial hole 72 in both left and right side wall surfaces 70, 71 of the mounting recess 38, and a second slide operating member 120 for fixing the position of the seat body 14 in the sliding direction is attached to the axial holes 74, 74 in a swingable manner.

[0046] As shown in Figure 4, the mounting recess 38 is provided with a first fixing means 140 that fixes the rotational position of the seat body 14 relative to the base 12, and a second fixing means 80 that fixes the sliding position of the seat body 14 relative to the base 12.

[0047] As shown in FIGS. 8 and 9, the second fixing means 80 includes a first sliding operation member 90 and a second sliding operation member 120. As shown in FIGS.

[0048] The first slide operation member 90 has a pair of side bars 92, 92 and a connecting post 94 that connects the pair of side bars 92, 92 to each other at one end, and is formed in a substantially U-shape.

[0049] Two locking pieces 96 that can be locked with the through holes 62 are arranged on the rear end side (one end side) of the first slide operation member 90.

[0050] A cylindrical locking pin 98 that protrudes outward is formed at approximately the middle of the side bar 92 in the fore-and-aft direction. This locking pin 98 is inserted into the axial hole 74 on the seat body 14 side, and the first slide operating member 90 is held swingably around the locking pin 98.

[0051] A cylindrical axial pin 100 that protrudes inward is formed on the surface of the side bar 92 opposite the locking pin 98, and a bearing portion 154 of the rotation operating member 150 described later is fitted onto the outside of the axial pin 100, so that the rotation operating member 150 is held so as to be able to swing around the axial pin 100.

[0052] A spring receiving portion 102 is formed on the connecting pillar 94, and in the assembled state, as shown in FIG. 9, one end of a spring 104 that applies a biasing force to the first slide operation member 90 is held by this spring receiving portion 102.

[0053] An engagement portion 106 that can be engaged with a second slide operation member 120 is provided on the other end side of the first slide operation member 90 .

[0054] The engaging portion 106 is a rectangular flat plate and includes a flat plate portion 108 that protrudes upward and outward, and the upper end surface and left and right end surfaces of the tip end of the side bar 92.

[0055] The second slide operation member 120 has a pair of side bars 122 and a connecting post 124 that connects the pair of side bars 122 to each other at the other end, and is formed in a substantially U-shape.

[0056] A cylindrical locking pin 126 that protrudes outward is formed at approximately the middle of the side bar 122 in the front-to-rear direction, and this locking pin 126 is inserted into the axial hole 72 on the seat main body 14 side, so that the second slide operating member 120 is held swingably around the locking pin 126.

[0057] An engaged portion 127 engageable with the engaging portion 106 is provided on the rear end side (one end side) of the second slide operation member 120, and an operation surface 130 is provided on the front end side (the other end side).

[0058] The engaged portion 127 is a rectangular flat plate and includes an L-shaped portion 128 that extends inside the side bar 122 and then further downward, as well as the upper end surface and left and right end surfaces of the tip of the side bar 122.

[0059] The tip (front end) of the side bar 92 is inserted between the L-shaped portion 128 of the side bar 122 and the side bar 122, and the tip portion (rear end portion) of the side bar 122 is positioned outside the side bar 92 and below the flat portion 108 of the side bar 92, whereby the engaging portion 106 and the engaged portion 127 are engaged with each other.

[0060] When the locking piece 96 engages with the through hole 62 and the second fixing means 80 fixes the seat body 14, the engaging portion 106 and the engaged portion 127 come into contact so as to interlock with each other, restricting movement of each toward the seat body 14 and allowing movement only in the direction away from the seat body 14.

[0061] In this embodiment, the first slide operation member 90, the second slide operation member 120, the spring 104, and the through-hole 62 provided in the rotation member 44 constitute the second fixing means 80.

[0062] The first fixing means 140 includes a rotation operating member 150 .

[0063] As shown in Figures 10 and 11, the rotation operating member 150 has an overall Y-shape, and at the tip (rear end) of each of the bifurcated branches 152, a bearing portion 154 with a C-shaped cross section is formed so that it can be rotatably fitted from the outside to the outside of the shaft pin 100 of the first slide operating member 90.

[0064] A flat engagement claw 158 with a constant thickness protrudes downward from the underside of the rotation operation member 150. The engagement claw 158 extends linearly from the end of the Y-shaped rotation operation member 150 on the side of an operation surface 162 (described later) along the part that corresponds to the base of the Y, and its tip is arc-shaped.

[0065] An operation surface 162 is integrally provided on the end (front end) of the rotation operation member 150 opposite to the bearing portion 154.

[0066] A spring receiving portion 164 is formed on the surface opposite to the operating surface 162 of the rotation operating member 150. One end of a spring 166 is held by this spring receiving portion 164.

[0067] In this embodiment, the first fixing means 140 is composed of the rotation operation member 150, the spring 166, the engaged groove 48 provided in the base 12, and the engaged groove 60 provided in the rotation member 44. Furthermore, the rotation operation member 150 is rotatably supported on one end side by the first slide operation member 90, and an operation surface 162 is provided on the other end side, with the rotation axis being coaxial with the rotation axis of the first slide operation member 90.

[0068] FIG. 5 is a cross-sectional view of the seat body 14 fixed to the base 12 by the first fixing means 140 and the second fixing means 80. As shown in FIG.

[0069] The first slide operation member 90 of the second fixing means 80 is supported at the position of the shaft hole 74 (FIG. 4) so as to be swingable around a locking pin 98. The second slide operation member 120 of the second fixing means 80 is supported at the position of the shaft hole 72 (FIG. 4) so as to be swingable around a locking pin 126.

[0070] The rotation operation member 150 of the first fixing means 140 is supported at the position of a bearing portion 154 (FIG. 4) so as to be swingable around the pivot pin 100. The rotation operation member 150 ensures the strength of the first slide operation member 90.

[0071] 5 and other figures, a spring 104 is provided between the first slide operation member 90 and the mounting recess 38. More specifically, the spring 104 is interposed between the spring receiving portion 102 of the first slide operation member 90 and the rear spring receiving portion 37 of the mounting recess 38.

[0072] 5 and other figures, a spring 166 is provided between the rotation operation member 150 and the mounting recess 38. More specifically, the spring 166 is interposed between the spring receiving portion 164 of the rotation operation member 150 and the front spring receiving portion 36 of the mounting recess 38.

[0073] The downward biasing force of this spring 166 causes the rotation operation member 150 to swing counterclockwise around the shaft pin 100 in the drawing, and the engagement claw 158 protrudes toward the rotation member 44 side.

[0074] Meanwhile, the first slide operation member 90 swings clockwise in the drawing around the locking pin 98 due to the downward biasing force of the spring 104, and the locking piece 96 protrudes toward the base 12 side.

[0075] The operation surface 130 of the second slide operation member 120 can be pushed upward from below. The operation surface 162 of the rotation operation member 150 is substantially flush with the operation surface 130 and can be pushed upward from below.

[0076] In this embodiment, the fixed position of the seat body 14 in the rotational direction can be released by operating the operation surface 162 of the rotation operation member 150.

[0077] In addition, by operating the operating surface 130 of the second slide operating member 120, the rotation operating member 150 and the second slide operating member 120 come into contact, making it possible to release the fixed position of the seat main body 14 in the rotational direction and to release the fixed position of the seat main body 14 in the sliding direction.

[0078] In the first fixing means 140, as shown in Figure 5, the engaging claw 158 protruding toward the base 12 due to the biasing force of the spring 166 engages across the engaging groove 48 of the base 12 and the engaging groove 60 of the rotating member 44, thereby fixing the position of the seat body 14 in the rotational direction.

[0079] Here, as shown in Figure 12, when the operating surface 162 is pushed upward against the biasing force of the spring 166, the rotary operating member 150 swings clockwise, and the engaging claw 158 moves away from the engaged grooves 48 and 60, releasing the engaged state, and the seat body 14 becomes able to rotate around the central axis.

[0080] On the other hand, in the second fixing means 80, the locking piece 96 protruding toward the rotating member 44 due to the biasing force of the spring 104 engages with the through hole 62 provided in the rotating member 44, thereby fixing the position of the seat body 14 in the sliding direction (the front-to-back direction of the seat body 14).

[0081] 13, when the operation surface 130 is pushed upward against the biasing force of the spring 104, the first slide operation member 90 swings counterclockwise and the second slide operation member 120 swings clockwise, the locking piece 96 moves away from the through-hole 62, the rotation operation member 150 and the second slide operation member 120 come into contact, and the engaging claw 158 moves away from the engaged grooves 48 and 60, releasing the engaged state. This allows the seat main body 14 to slide forward and backward on the support surface 26 and to rotate about the central axis.

[0082] The child car seat 10 having the above configuration comprises a base 12 attached to a vehicle seat, a seat body 14 rotatable and reclining relative to the base 12, and a rotation member 44 rotatable relative to the base 12, and the seat body 14 is engaged and connected to the rotation member 44 so as to be slidable relative to the base 12. The seat body 14 has a mounting recess 38 formed as a bottomed hole extending from the bottom to the top on the underside thereof. The rotary member 44 is provided with a through hole 62 as a locking hole, a first fixing means for fixing the position of the seat body relative to the base in a rotational direction, and a second fixing means for fixing the position of the seat body relative to the base in a sliding direction; The first fixing means 140 includes a rotation operating member 150, The second fixing means 80 includes a first slide operating member 90 and a second slide operating member 120. The first slide operation member 90 is formed in a U-shape and has a pair of side bars 92, 92 and a connecting post 94 that connects the pair of side bars 92, 92 at one end, and has a locking piece 96 that can be locked with a through hole 62 as a locking hole arranged at one end, and an engaging portion 106 that can be engaged with a second slide operation member 120 arranged at the other end, The second slide operation member 120 is formed in a U-shape and has a pair of side bars 122, 122 and a connecting post 124 that connects the pair of side bars 122, 122 at the other end side. An engaged portion 127 that can engage with the engaging portion 106 is provided at one end side, and an operation surface 130 is provided at the other end side. The first slide operation member 90 and the second slide operation member 120 are pivotally supported in the mounting recess 38 so that their rotation axes are parallel to each other. When the engaging portion 106 and the engaged portion 127 are engaged with each other and the second fixing means 80 fixes the seat body 14, the engaging portion 106 and the engaged portion 127 are configured to be allowed to move only in the direction away from the seat body 14, The rotation operation member 150 is rotatably supported at one end relative to the first slide operation member 90, has an operation surface 162 disposed at the other end, has a rotation axis coaxial with the rotation axis of the first slide operation member 90, and has an engaging claw 158 engageable with the engaged grooves 48 and 60 disposed in the rotation member 44 and the base 12, The surface of the other end of the rotation operating member 150 opposite the seat body 14 is capable of abutting against the surface of the other end of the second slide operating member 120 on the seat body 14 side, and the operating surfaces 162 and 130 of the rotation operating member 150 and the second slide operating member 120, respectively, are pressed from the side away from the seat body 14.

[0083] According to this, when operating operation surfaces 162 and 130 of rotation operation member 150 and second slide operation member 120, they are pressed from the side away from seat main body 14, or in other words, they can be operated from the same direction, improving operability. Furthermore, by configuring second fixing means 80 as being divided into first slide operation member 90 and second slide operation member 120, the operating area of each member is reduced, allowing for a more compact structure.

[0084] Furthermore, the rotation operation member 150 is disposed so as to span between the side bars 92 of the first slide operation member 90 at one end side.

[0085] According to this, the strength of the first sliding operation member 90 can be ensured by the rotation operation member 150.

[0086] In addition, by operating the operation surface 162 of the rotation operation member 150, the fixed position of the seat body 14 in the rotation direction can be released. By operating the operating surface 130 of the second slide operating member 120, the rotation operating member 150 and the second slide operating member 120 come into contact, making it possible to release the fixed position of the seat main body 14 in the rotational direction and the fixed position of the seat main body 14 in the sliding direction.

[0087] This makes it possible to select and operate two modes: only releasing the fixation of the rotational position of the seat body 14, and releasing the fixation of the rotational position of the seat body 14 and the sliding position of the seat body 14.

[0088] The child car seat of the present invention is not limited to the above-described configuration, and various design modifications are possible without departing from the spirit and scope of the present invention.

[0089] For example, in the above embodiment, a connecting protrusion is provided on the rotating member 44 and an opening is provided on the seat main body 14, but in some cases it is also possible to provide an elongated hole-shaped opening on the rotating member 44 and a connecting protrusion on the seat main body 14, and various other modifications can be made within the scope of the invention.

[0090] Furthermore, the support structure for the protrusion portion by the guide rail 40 can be the same as that described in Patent Application No. 2015-198925 (Patent Publication No. 6093420) previously filed by the applicant (see Patent Publication No. 6093420, Figure 11, etc.).
