是使幼兒的膝蓋不要超過膝蓋支撐面52且露出於左右方向 外側。作為目標，可將臀支撐面5丨之左右方向的幅度Wc(參 照第16圖）設定為MOrnm左右，並可將前後方向上朝内的部 分Dc(參照第4圖）分別設定成80mm左右。又’如第16圖所 20示’亦可將對於將臀部槻墊50分成左右方向二等分之中心 線CLc方向之膝蓋支撐面52的傾斜角度0c設定成45。左右。 又’如第4圖所示’臀部襯墊50係藉由於表皮材56之内側設 置内裝材57而形成，而前述内裝材57係具有適當的緩衝性 之彈性材料者。又，表皮材56及内裝材57之素材可選擇與 14 1378043 頭部襯墊10之表皮材16及内裝材17相同的素材。内裝材57 可設於背部襯墊5〇之全面，亦可只設於一部分。再者，如 第3圖所示，臀部襯墊5〇後端侧之兩側緣設有朝左右方向之 中心部後退的縮入部58，而該縮入部58係設置成可將兒童 5座椅2之腰帶8環繞於臀部襯墊50之表側者。 如第1圖所示，在具有以上結構之墊丨中，臀部襯墊5〇 係裝置於座椅部5,另一方面，背部襯墊3〇係配置於椅背部 6並可連接前述臀部襯墊5〇之後端，而頭部襯墊1〇係裝置於 前述背部襯墊30之上方。腿帶7係插入臀部襯墊5〇之皮帶環 10孔54 ’而腰帶8係從臀部襯墊5〇之後端拉至墊i之表側，而 且肩帶9係從背部襯塾3〇與頭部襯塾的間隙拉至塾丨之表 側。藉此，可將幼兒安置在安裝於座椅2之墊〗的表側，並 可利用皮帶7、8、9拘束幼兒。 以下針對當如前所述將幼兒安置於兒童座椅2上時墊1 15之作用加以說明。首先，在頭部襯墊10中，幼兒的頭部係 放置於凹部15且由凹部支撐。在該狀態下，如第17圖所示， 頭部襯墊10之頸支撐部12緊靠於幼兒1〇〇的後頸，並從背後 支撐頸部。藉此，可將幼兒100之頭部101保持於其下顎稍 微抬高之姿勢，因此，可防止壓迫幼兒之呼吸道’而讓幼 20兒舒適地呼吸。而且，由於頸支撐部12如第7圖及第8圖所 示彎曲成凹曲線’因此可將幼兒1〇〇之頸部自然地固定於左 右方向的中央位置。再者，由於凹部15兩側之頭部兩側支 撐面14可從兩側支撐幼兒100的頭部101，因此可使頭部1〇1 自然地朝向正面’並可防止頭部之侧倒及橫向偏移等。該 15 1378043 等作用對於料尚未驗直之軌_有效。再者’由於 =15之上緣側未被突出部圍住，而一 •㈣之上緣 4形成開口，因此可提高幼兒的開放感。 5 背部襯塾3〇中，幼兒之背部係由背支揮面騎支撐， 且如第_麟，腋下切面珊從外側幼兒⑽的身 躺102，並從側邊支撑身船〇2。藉此，可防止幼脚身聽 的橫向偏移。由於背支撐面31從背部襯墊之 侧傾斜並畫&向下斜面’因此可❹切仙，特別是背 支撐面31之下側從背後充分地接觸幼兒的腰，藉此可利用 背部襯墊提高保持幼兒姿勢之效果。 臀部襯塾50中，如第19圖所示，臀支揮面川系緊靠幼 兒100的臀部103，以支撐臀部1〇3。由於臀支撐面51朝臀部 襯墊50之前方且具有向上斜面，因此可抑制臀部1〇3朝兒童 座椅2之前方偏移，因此腹部不會因臀部向前偏移而彎曲或 15產生壓迫。又，由於臀支撐面51具有彎曲，且該傾斜面51a 與臀部之側邊相接觸，因此臀支撐面51可與臀部1〇3相接觸 且圍住臀部103 ’故，可利用臀支撐面51提高保持姿勢之效 果。 再者，在臀部櫬墊50中，由於膝蓋支標面％從外側接 20觸並支撐幼兒100的膝蓋104,因此可使膝蓋104適度地向内 彎曲。藉此’可抑制膝蓋104朝外侧打開，並可將下肢1〇5 保持於適當的方向。因此，可適度的保持幼兒1〇〇下半身屈 肌與伸肌的平衡，並可防止身體的變形與萎縮。由於膝蓋 支撐面52較臀支撐面51朝前方延伸，因此可以臀支撐面51 16 1378043 支撐臀部103，並可以膝蓋支撐面確實地承受位於臀部1〇3 前方之膝蓋104。再者，由於可以腳支撐面52支撐因膝蓋支 撐面52而朝内側彎曲的下肢1 〇5，因此可使下肢1 〇5成為以 自然地姿勢向前方延伸的狀態。 5 在本型態之墊1中，由於頭部襯墊10、背部襯墊3〇及臀 部襯墊50分別由可互相分離之另外構件所構成，因此可根 據幼兒的成長階段適當的選擇並使用該等襯墊1〇、3〇、5〇。 作為一例’可選擇於新生兒期（體重2.5kg〜7kg)使用全部的 襯墊10、30、50，於乳兒前期（體重7kg〜9kg)只使用頭部襯 10墊1〇 ’於乳兒後期（體重9kg以上)却下全部概塾，即，不使 用墊1等的使用型態。又，亦可選擇於新生兒前期卸下全部 襯墊之使用型態、於乳兒前期只使用臀部襯墊5〇之使用型 態、及於乳新生兒期只使用任兩個襯墊之使用型態。 接著，以第20圖及第21圖表示用以將頭部襯墊1〇安裝 15於椅背部6之結構的一例。在該例中，係將一對安裝皮帶60 固定於頭部襯墊1〇之裡側，並將各皮帶6〇之其中一端插入 設於座椅本體4之椅背部6的肩帶環孔6a，且將另一端從椅 背部6之上端環繞至椅背部6之裡側，再以連結工具“連結

The inclined surface 33 is provided to prevent interference of the back pad 30 with the hip pad 50 when the back pad 20 is disposed on the child seat 2, that is, due to the seat portion 5 and the seat back 6 of the child seat 2 There is a curved portion between them, so when the hip pad 50 is disposed at the rear end of the seat portion 5, and the back pad 30 is disposed at the lower end of the seat back 6, the back end of the buttock pad 5 干扰 interferes with the back lining At the lower end of the pad 30, there is a 12 1378043 <capacity that cannot be continuously arranged. The inclined surface 33 is provided to prevent the aforementioned disturbers, and the hips can be arranged side by side. It is preferable that the size of each part of the moon pad 3G is appropriately set according to the physique of the child child for the child seat 2. However, the curvature of the back is generally 5, and it is shaped to match the curve from the back of the child to the film under the sides. As the target', the width in the left-right direction of the undercut surface 31 shown in Fig. 12 can be set to about 14G to i6Gmm, and the underarm support can be used to divide the back pad into the center line CLb direction which is halved in the left-right direction. The inclination angle 0b of the face 32 is set to 45. about. As shown in Fig. 4, the back pad 3 is formed by providing the inner material 35 on the inner side of the skin material 34 of the table 10, and the inner material 35 is an elastic material having a suitable cushioning property. Further, the material of the surface material 34 and the inner material 35 may be the same material as the surface material 16 and the inner material 17 of the head gasket 10. The inner material 35 may be provided in the entirety of the back pad 30 or may be provided only in one part. 15 As shown in FIGS. 2 to 4 and 13 to 16 , the buttocks 5 〇 have a buttock support surface 51 and a pair of the left and right sides of the buttocks from the hip support surface And the knee support surface 52 of the upward slope is pulled out. Further, in Fig. 13, the rear end of the buttock pad 50 corresponds to the left end of the figure, and in Fig. 15, the rear end of the buttock pad 50 corresponds to the upper end of the figure. As can be seen from Fig. 4, the buttock support surface 51 is inclined forward from the rear end of the buttock pad and the upper slope is pulled out. Further, as indicated by the broken line in Fig. 14, from the front of the buttocks pad 50, the buttock support surface 51 is centered on the center portion of the buttocks pad 50 in the left-right direction and faces the knee support surface 52 in the height direction. Bend into a concave curve. Thus, as shown by the oblique line portion of Fig. 15, the two ends of the knee support surface 52 are formed. 13 1378043 has inclined sills for supporting the sides of the child's buttocks, and the inclined surfaces are smoothly matched with the knee support surface 52. Connected. As can be seen from Fig. 3, the knee support surface 52 extends slightly beyond the buttocks 50 from the hip support surface 51. Thereby, the hip support surface 51 can support the buttocks, and the knee support surface _ 5 can be used to bear the child's knees. As can be understood from FIGS. 3 and 4, the front side of the buttocks selection surface 51 is formed with a foot supporting surface extending toward the front end of the buttock pad 50 and a downward inclined surface, and the foot supporting surface 53 is penetrated. The belt loop hole 54 through which the leg belt 7 (refer to the exhaustion) passes. Further, the position of the ridge 55 as the boundary between the hip-selecting surface and the foot-selecting surface H) is appropriately set according to the width required for the hip-receiving surface 51. The size of each of the buttocks 50 is preferably set according to the physique of the child who is the child seat 2 as an object. However, the buttock support surface 51 is preferably set to fit the buttocks of the child, and in particular, it is preferably set to fit the size of the diaper surface of the child's buttocks, and the knee support surface 52 is preferably The child's knees should not exceed the knee support surface 52 and be exposed to the outside in the left and right direction. As a target, the width Wc (refer to Fig. 16) in the left-right direction of the buttock support surface 5丨 can be set to about MOrnm, and the portion Dc (see Fig. 4) facing in the front-rear direction can be set to about 80 mm. Further, the angle of inclination 0c of the knee supporting surface 52 in the direction of the center line CLc which divides the buttocks 50 into the left and right directions may be set to 45 as shown in Fig. 16. about. Further, as shown in Fig. 4, the buttocks pad 50 is formed by providing the inner material 57 on the inner side of the surface material 56, and the inner material 57 is an elastic material having an appropriate cushioning property. Further, the material of the surface material 56 and the inner material 57 may be the same material as the surface material 16 and the inner material 17 of the head gasket 10 of 14 1378043. The inner material 57 may be provided in the entire back pad 5 , or may be provided only in a part. Further, as shown in Fig. 3, the side edges of the rear end side of the buttocks 5 are provided with retracted portions 58 which are retracted toward the center portion in the left-right direction, and the retracted portions 58 are provided to allow the child 5 seats A belt 8 of 2 surrounds the front side of the buttocks pad 50. As shown in Fig. 1, in the pad having the above structure, the buttocks 5 are attached to the seat portion 5. On the other hand, the back pad 3 is disposed on the seat back 6 and can be connected to the buttocks. The pad 5 is at the rear end, and the head pad 1 is attached to the back pad 30. The leg strap 7 is inserted into the hip pad 5 皮带 belt loop 10 hole 54 ' and the waist strap 8 is pulled from the hip pad 5 〇 rear end to the front side of the pad i, and the shoulder strap 9 is lining the back from the back 3 〇 The gap of the lining is pulled to the front side of the cymbal. Thereby, the child can be placed on the front side of the seat mounted on the seat 2, and the child can be restrained by the belts 7, 8, 9. The following is a description of the role of the pad 1 15 when the child is placed on the child seat 2 as described above. First, in the head pad 10, the head of the child is placed in the recess 15 and supported by the recess. In this state, as shown in Fig. 17, the neck supporting portion 12 of the head pad 10 abuts against the back neck of the young child 1 and supports the neck from the back. Thereby, the head 101 of the infant 100 can be held in a posture in which the lower jaw is slightly raised, so that the breathing passage of the infant can be prevented from being pressed, and the young child 20 can be comfortably breathed. Further, since the neck supporting portion 12 is curved into a concave curve as shown in Figs. 7 and 8, the neck of the young child can be naturally fixed to the center position in the left and right direction. Furthermore, since the support surfaces 14 on both sides of the head on both sides of the recess 15 can support the head 101 of the infant 100 from both sides, the head 1〇1 can be naturally oriented toward the front side and the side of the head can be prevented from falling. Lateral offset, etc. The role of the 15 1378043 and other functions is valid for the track that has not been straightened. Furthermore, since the upper edge side of =15 is not surrounded by the protruding portion, and the upper edge 4 of (4) forms an opening, the opening feeling of the child can be improved. 5 In the back lining 3 ,, the back of the child is supported by the back support, and as the _ _ Lin, the undercut cuts from the outer child (10) lying 102, and supports the body 〇 2 from the side. Thereby, the lateral shift of the baby's foot can be prevented. Since the back support surface 31 is inclined from the side of the back pad and draws a downward slope, it can be cut, and in particular, the lower side of the back support surface 31 sufficiently contacts the waist of the child from the back, thereby utilizing the back lining The pad improves the effect of maintaining the posture of the child. In the buttocks 50, as shown in Fig. 19, the buttocks of the hips are close to the buttocks 103 of the infant 100 to support the buttocks 1〇3. Since the buttock support surface 51 faces the hip pad 50 and has an upward slope, it is possible to prevent the buttocks 1〇3 from shifting toward the front of the child seat 2, so that the abdomen does not bend or 15 presses due to the forward bias of the buttocks. . Moreover, since the buttock support surface 51 has a curvature and the inclined surface 51a is in contact with the side of the buttocks, the buttock support surface 51 can be in contact with the buttocks 1〇3 and surround the buttocks 103'. Therefore, the buttock support surface 51 can be utilized. Improve the effect of maintaining posture. Further, in the buttocks 50, since the knee facet % is 20-contacted from the outside and supports the knee 104 of the child 100, the knee 104 can be appropriately bent inward. Thereby, the knee 104 can be prevented from opening to the outside, and the lower limb 1〇5 can be held in an appropriate direction. Therefore, the balance between the flexor and extensor muscles of the lower body of the lower body can be appropriately maintained, and the deformation and atrophy of the body can be prevented. Since the knee support surface 52 extends forward toward the buttock support surface 51, the buttock support surface 51 16 1378043 can support the buttocks 103, and the knee support surface can surely receive the knee 104 in front of the buttocks 1〇3. Further, since the lower limb 1 〇 5 which is bent inward by the knee supporting surface 52 can be supported by the foot supporting surface 52, the lower limb 1 〇 5 can be extended forward in a natural posture. 5 In the pad 1 of the present type, since the head pad 10, the back pad 3〇 and the buttock pad 50 are respectively formed of separate members which are separable from each other, it can be appropriately selected and used according to the growth stage of the child. The pads are 1 〇, 3 〇, 5 〇. As an example, it is possible to use all the pads 10, 30, and 50 in the neonatal period (weight: 2.5 kg to 7 kg). In the pre-pregnancy period (body weight: 7 kg to 9 kg), only the head lining 10 pad 1 〇 'in the late stage of the baby is used. The weight is 9 kg or more, but all of them are summarized, that is, the use type of the pad 1 or the like is not used. In addition, it is also possible to select the type of use of all the pads in the early stage of the newborn, the use type of the buttocks only in the early stage of the baby, and the use of only two types of pads in the neonatal period. state. Next, an example of a structure for attaching the head pad 1 to the seat back 6 will be described with reference to Figs. 20 and 21. In this example, a pair of mounting belts 60 are fixed to the inner side of the head gasket 1〇, and one end of each belt 6 is inserted into the shoulder belt loop hole 6a provided in the seat back 6 of the seat body 4. And the other end is wound from the upper end of the seat back 6 to the inner side of the seat back 6, and the connecting tool "connects the two ends of the belts 60, and the belts 60 are connected in a ring shape. Further, the connecting device 2〇61 Various fastening devices such as a buckle, a fastening tape, and a hook can be used. Fig. 22 and Fig. a are diagrams showing another example of a structure in which the head pad 1〇 is attached to the seat back 6. In this example, the head is to be used. A lining base 65 formed of another member of the lining is disposed on the back side of the head pad 1 ,, and the base pad 65 and the head pad 1 连结 are coupled by a coupling tool 66. The base 17 1378043 65 can be mounted to the seat back 6 using suitable means. Also, the back pad 30 can be replaced by the back pad 30, or the back pad 30 can be mounted in addition to the head pad 10, and the back The pad 3 is attached to the seat back 6 in the same configuration as described above. Alternatively, it can be adjusted upwards 5 above the seat back 6. The position of the pad 1 , can also change the position of the head pad 10 in accordance with the head of the child, and the back pad 3 〇 is also the same as described above. Also, the pad is mounted on the child seat. The structure is not limited to the foregoing examples, and may be appropriately changed. For example, the pads may be attached to the child seat cover or the child seat 10 chair using appropriate means such as hooks, ropes, buckles, buttons, and the like. The inner material (the mat or the base plate). Further, any one of the spacers may be coupled to the child seat 2, and another pad may be coupled to the pad, thereby mounting the pads on the pad. In the child seat 2, when two or more pads are connected to each other, the pads may be a separable structure or an inseparable structure. Hereinafter, several examples are given for joining the pads 1 The structure of 〇, 30, and 50 is exemplified. Fig. 24A to Fig. 24E show an example of a joint portion 70 for joining the head pad 1 〇 and the back pad 30. In the example of Fig. 24A, A strip portion 71' is disposed at the center of the upper edge of the back lining 3〇 and is respectively connected to the surface of the strip portion 71 and the head pad ίο The adhesive tapes 72A, 72B are combined. The head pad 1 〇 and the back pad % can be connected by the viscous 20 buckles f 72A, 72B. In this example, the upper and lower seats 2 are moved upwards and downwards. The overlapping range of the adhesive tape ΜΑ and 72B can change the position of the head pad 10 in the up and down direction with respect to the back pad 3. Alternatively, the tape can be made into a phaseable portion lining 30 by Adjust the position in the up and down direction to enlarge the range of the adjustment position 18 (S ) 1378043 of the head lining 1 . Since the adhesive strip 72B of the head gasket 10 is in contact with the skin of the seat 2, it is best The head pad 1〇 is a concave side having no hook-like protrusions, that is, a loop-side adhesive tape. In the example of Fig. 24B, a pair of strip portions 5 73 are provided on the upper edge of the back pad 3〇. And a hook 74A is attached to the surface of each of the strip portions 73, and a plurality of hooks 74B' engageable with the hooks 74A are respectively attached at positions corresponding to the strip portions 73 on the inside of the head pad 10, and the aforementioned hooks 74B is attached to the up and down direction at appropriate intervals. In this example, the back pad 3's hook μα is engaged with the hook 74B at any position of the head pad 10 to join the head pad 1〇 and the back 10 pad 3〇. And by changing the hook 7/^ which should be engaged with the hook 74A, the position of the head pad 10 with respect to the back pad 3 in the up and down direction can be changed. In the example of Fig. 24C, the hooks 74A, 74B are engaged to join the head pad 1 and the back pad 30 as in the case of Fig. 24B. However, the slider guides 75 extending to the upper and lower directions 15 are respectively disposed at positions corresponding to the strip portions 73 of the head pad 10, and one of the slider guides 75 is mounted on the slider guides 75 in the up and down direction. The hook 74B of the freely adjustable position is different from the example of Fig. 24B. In this example, the position of the head pad 10 with respect to the back pad 3 in the up and down direction can be changed by changing the position of the hook portion 74B of the head pad 1 in the up and down direction. In the case of the 24D®, the lower edge of the head lining 10 is equipped with a pair of 20 20, and a back pad 3G - a plurality of the upper and lower directions of the band-shaped ridges are respectively provided for the passage of the button 76. 77, and the aforementioned buttonholes are installed at intervals in the vertical direction. In this example, the head slit 1G and the backing lining can be joined by passing the New% through any of the buttonholes 77', and the head lining can be changed by changing the selection of the shinning holes 77. The position of the lion is in the direction of 19 1378043. Fig. 24E is a modification of Fig. 24A, in which the cover 78' covering the adhesive tape 72B is added to the inner side of the head pad 1〇, and the band 71 of the back pad 3 is passed through the cover 78. The lower end opening portion can be inserted into the inner side 5 of the cover 78. In this example, since the fastening tape 72B is not exposed inside the head pad 1 ,, the fastening tape 72B can also be used as the fastening tape having the convex side of the hook-like projection. Further, in the examples of Figs. 24 to 24E, the spacers 10 and 30 can be similarly connected even if the components provided on the back pad 10 and the back pad 30 are replaced with each other. 10A to 25C show an example of a joint portion 80 for joining the back pad 30 and the buttock pad 50. Fig. 25A shows an example in which the hook 82A provided on one of the lower edges of the back pad 30 and the hook 82A provided on the inner side of the buttock pad 50 are engaged with the spacers 30, 50. Fig. 25B shows an example in which the fastening tape 84A provided in the strip portion 83 at the center of the lower edge of the back pad 30 is overlapped with the fastening tape 84B provided in the buttock pad 50 15 to join the spacers 30, 50. Fig. 25C shows an example in which the button 85 provided on the inner side of the buttock pad 50 is passed through the buttonhole 86 of the band portion 81 of the back pad 30 to join the pads 30, 50. Further, even in the examples of Figs. 25A to 25C, the components provided on the back pad 30 and the buttock pad 50 can be replaced with each other. Further, in the example of Fig. 25B, it is preferable that the fastening tape 20 84B is a hook tape of a convex side.
