緊固帶53於靠背基體部41之內部向下方行進，自設置於該靠背基體部41之中央下表面46之靠背側帶插通孔47(圖4)拉出至外部。又，緊固帶53自設置於座位部11之後中央突出部27之座位側帶插通孔28(圖3)進入該座位部11之內部，朝前方行進並自該座位部11之前端附近拉出至前方。The fastening belt 53 runs downward inside the backrest base part 41 and is pulled out to the outside from the backside belt insertion hole 47 ( FIG. 4 ) provided on the central lower surface 46 of the backrest base part 41 . Also, the fastening belt 53 enters the inside of the seat portion 11 from the seat side band insertion hole 28 ( FIG. 3 ) of the central protrusion 27 which is arranged on the back of the seat portion 11 , advances forward and pulls it near the front end of the seat portion 11 . out to the front.
再者，肩帶52及緊固帶53以可沿長度方向滑動之方式插通靠背基體部41及座位部11之內部。又，於座位部11之前端附近，設置有固定緊固帶53，或解除固定之帶止擋件58(圖2)。Furthermore, the shoulder belt 52 and the fastening belt 53 are inserted through the interior of the backrest base part 41 and the seat part 11 so that they may slide along the longitudinal direction. Also, near the front end of the seat portion 11, a fastening belt 53 for fixing or a belt stopper 58 for releasing the fixing is provided (FIG. 2).
該安全帶群4於嬰幼兒就座之狀態下，以使各肩帶52通過該嬰幼兒之肩膀之上側至前側之方式配置，將左右之鎖舌55組合後***至搭扣54，進而將緊固帶53向前方拉出。藉此，安全帶群4可將嬰幼兒之肩膀至腰之範圍束縛至兒童座椅本體2之靠背部12，可將該嬰幼兒維持就座狀態。This safety belt group 4 is under the state that infant is seated, makes each shoulder strap 52 pass the mode disposition from the upper side of the shoulder of this infant to the front side, inserts the locking tongue 55 of left and right sides into buckle 54 after combining, and then The fastening belt 53 is pulled out forward. Thereby, the safety belt group 4 can bind the range from the shoulders to the waist of the infant to the backrest 12 of the child seat body 2, and the infant can be kept in a seated state.
[4.頂部繫帶之構成] 圖5係顯示頂部繫帶5之概略立體圖。頂部繫帶5大致由繫帶71、調節部72、連接帶73及繫帶金屬件74構成。 [4. Composition of the top tie] FIG. 5 shows a schematic perspective view of the top tether 5 . The top strap 5 is roughly composed of a strap 71 , an adjustment portion 72 , a connecting strap 73 and a strap metal piece 74 .
繫帶71與安全帶群4之肩帶52(圖1)等同樣，構成為具有較長之寬度及較短之厚度且具有充足長度之繫繩狀，具有柔軟性且具有充足之拉伸強度。該繫帶71之一端固定於靠背部12之繫帶安裝部43(圖4)。以下，關於繫帶71之長度方向，將固定於繫帶安裝部43之側稱為固定側，將其相反側稱為前端側。又，繫帶71作為一例，可將帶寬設為約40[mm]。The tie belt 71 is the same as the shoulder belt 52 (FIG. 1) of the safety belt group 4, etc., and is formed into a tether shape with a long width and a short thickness and a sufficient length, and has flexibility and sufficient tensile strength. . One end of the tether 71 is fixed to the tether mounting portion 43 of the backrest 12 ( FIG. 4 ). Hereinafter, regarding the longitudinal direction of the tether 71, the side fixed to the tether attaching portion 43 is referred to as the fixed side, and the opposite side is referred to as the front end side. In addition, the belt 71 can be set to a width of about 40 [mm] as an example.
調節部72以如使剖面為三角形之柱狀體(即三角柱)橫轉之形狀之本體部81為中心而構成。本體部81作為一例，可將沿該三角柱之中心軸(未圖示)之方向之長度(以下，亦將其稱為本體部81之寬度)設為約65[mm]。又，本體部81可將三角形中最長邊之長度設為約80[mm]，將至以該最長邊為對邊之頂點之長度(以下，亦將其稱為本體部81之高度)設為約28[mm]。The adjusting part 72 is configured around the main body part 81 having a shape such as a columnar body (that is, a triangular prism) with a triangular cross-section as the center. As an example, the length of the main body portion 81 along the central axis (not shown) of the triangular prism (hereinafter, also referred to as the width of the main body portion 81 ) can be set to about 65 [mm]. Also, the length of the longest side of the triangle can be set to about 80 [mm] for the main body portion 81, and the length to the vertex (hereinafter also referred to as the height of the main body portion 81) with the longest side as the opposite side can be set to About 28 [mm].
於本體部81，設置有用以使繫帶71插通之繫帶插通孔82，或用以使連接帶73插通之連接帶插通孔83等。繫帶插通孔82及連接帶73皆形成為沿本體部81之三角柱之中心軸(未圖示)之細長的狹縫狀。The main body portion 81 is provided with a belt insertion hole 82 through which the belt 71 is inserted, or a belt insertion hole 83 through which the belt 73 is inserted. Both the tie insertion hole 82 and the connection belt 73 are formed in the shape of an elongated slit along the central axis (not shown) of the triangular prism of the main body 81 .
又，調節部72中，按壓於繫帶71之按壓零件(未圖示)、將該按壓零件朝繫帶71彈推之彈推零件(未圖示)等設置於本體部81內，再者，設置有受理保護者等之操作之操作部84。Also, in the adjustment part 72, a pressing part (not shown) that presses the frenulum 71, an elastic push part (not shown) that pushes the pressing part toward the frenulum 71, etc. are arranged in the main body part 81. , an operation unit 84 for accepting operations by a protector or the like is provided.
調節部72於繫帶71插通繫帶插通孔82之狀態下，藉由彈推零件將按壓零件按壓於該繫帶71。藉此，調節部72相對於該繫帶71之位置固定。The adjustment part 72 presses the pressing part to the tie belt 71 by the elastic pushing part in the state where the tie tie 71 is inserted through the tie insertion hole 82 . Thereby, the position of the adjustment part 72 relative to the strap 71 is fixed.
又，當由保護者等操作(具體而言，***)操作部84時，調節部72可將按壓零件暫時與繫帶71離開，將相對於該繫帶71之位置向固定側或前端側變更。其後，當解除對操作部84之操作時，調節部72藉由彈推零件之作用將按壓零件按壓於繫帶71，保持相對於該繫帶71之當前位置。Moreover, when the operation part 84 is operated (specifically, inserted) by a protector, the adjustment part 72 can temporarily separate the pressing part from the tether 71, and change the position relative to the tether 71 to the fixed side or the front end side. . Thereafter, when the operation on the operation part 84 is released, the adjustment part 72 presses the pressing part against the tether 71 by the action of the spring pushing part, and maintains the current position relative to the tether 71 .
連接帶73由與繫帶71相同之帶狀構件構成，具有柔軟性且具有充足之拉伸強度。該連接帶73之一端插通調節部72之連接帶插通孔83，另一端插通繫帶金屬件74。作為一例，連接帶73可將調解部72與繫帶金屬件74之間隔設為約40[mm]。The connection belt 73 is composed of the same belt-shaped member as the tie belt 71, and has flexibility and sufficient tensile strength. One end of the connecting strap 73 is inserted through the connecting strap insertion hole 83 of the adjusting portion 72 , and the other end is inserted through the tie metal piece 74 . As an example, the connection belt 73 may set the distance between the adjustment part 72 and the tie metal fitting 74 to about 40 [mm].
繫帶金屬件74為於本體部91安裝有彈簧部92之構成。本體部91藉由切削具有充足厚度之鋼板及使之撓曲，而整體構成為細長之形狀。該本體部91之長度方向之一側即根部側形成為較寬幅，且於該根部側穿設有用以使連接帶73插通之插通孔91H。The tie metal fitting 74 has a structure in which a spring portion 92 is attached to a main body portion 91 . The main body portion 91 is formed in an elongated shape as a whole by cutting and bending a steel plate having a sufficient thickness. One side in the longitudinal direction of the main body portion 91 , that is, the root side is formed to have a wider width, and an insertion hole 91H for inserting the connection belt 73 is formed on the root side.
本體部91之與根部側相反之前端側較細地形成，且以其前端部分向根部側圓弧狀折回之方式撓曲。換言之，自側方觀察之情形時，本體部91之前端側為如大寫英文字母「J」或使之反轉之形狀。以下，將本體部81之前端部分稱為前端部93。The front end side of the main body part 91 opposite to the root side is formed thinner, and the front end part is bent so that the front end part is arcuately turned back toward the root side. In other words, when viewed from the side, the front end side of the main body portion 91 is shaped like a capital letter “J” or reversed. Hereinafter, the front end portion of the main body portion 81 is referred to as a front end portion 93 .
又，繫帶金屬件74作為一例，可將本體部91之長度方向之長度設為約80[mm]，可將寬度方向之長度設為約25[mm]。再者，繫帶金屬件74可將把前端部93視為圓弧時之直徑設為約20[mm]。In addition, as an example of the tie metal fitting 74, the length in the longitudinal direction of the main body portion 91 can be set to about 80 [mm], and the length in the width direction can be set to about 25 [mm]. In addition, the tie metal fitting 74 may have a diameter of about 20 [mm] when the front end portion 93 is regarded as an arc.
彈簧部92為較本體部91充分薄且細長之金屬板，平緩彎曲且具有彈性。彈簧部92之一端固定於本體部91之根部側，另一端與前端部93之內側抵接。The spring part 92 is a sufficiently thinner and slender metal plate than the main body part 91, and is gently curved and elastic. One end of the spring portion 92 is fixed on the root side of the main body portion 91 , and the other end abuts against the inner side of the front end portion 93 .
若該繫帶金屬件74以使彈簧部92暫時靠近本體部91之方式變形，且將前端部93鉤掛於特定之固定金屬件等，則彈簧部92可藉由復原作用恢復至原來的形狀，維持與該固定金屬件卡合之狀態。If the tie metal piece 74 is deformed so that the spring portion 92 is temporarily close to the main body portion 91, and the front end portion 93 is hooked to a specific fixing metal piece, etc., the spring portion 92 can be restored to its original shape by a restoring action. , to maintain the state of engagement with the fixed metal piece.
然而，兒童座椅1之各部之長度亦可以將頂部繫帶5之繫帶71之帶寬(作為一例，約為40[mm])作為基準之相對長度表示。以下，將繫帶71之帶寬稱為基準帶寬WB。However, the length of each part of the child seat 1 can also be expressed as a relative length based on the width of the tether 71 of the top tether 5 (for example, about 40 [mm]). Hereinafter, the bandwidth of the tether 71 is referred to as a reference bandwidth WB.
即，調節部72之本體部81以基準帶寬WB為基準，沿三角柱之中心軸(未圖示)之方向之長度為約1.65倍，最長邊之長度為約2倍。又，連接帶73之調節部72與繫帶金屬件74之間隔與基準帶寬WB大致同等。再者，繫帶金屬件74之長度方向之長度為基準帶寬WB之約2倍。That is, the main body portion 81 of the adjustment portion 72 is about 1.65 times the length along the central axis (not shown) of the triangular prism, and about 2 times the length of the longest side, based on the reference bandwidth WB. In addition, the distance between the adjusting portion 72 of the connection belt 73 and the tie metal fitting 74 is substantially equal to the reference width WB. Furthermore, the length of the tie metal piece 74 in the longitudinal direction is about twice the reference width WB.
又，上述座位部11之收納凹口26(圖2及圖3)以基準帶寬WB為基準，前後方向之長度為約3.5倍，左右方向之長度為約2.75倍，座位面頂部21ST附近之深度(上下方向之長度)為約1.25倍。Also, the accommodation notch 26 (Fig. 2 and Fig. 3) of the above-mentioned seat portion 11 is based on the standard bandwidth WB, the length in the front-rear direction is about 3.5 times, the length in the left-right direction is about 2.75 times, and the depth near the top of the seat surface 21ST (The length in the vertical direction) is about 1.25 times.
即，收納凹口26之前後方向及左右方向之長度充分大於(長於)調節部72之本體部81之最長邊之長度，或繫帶金屬件74之長度方向之長度。That is, the lengths of the receiving notch 26 in the front, back and left and right directions are sufficiently longer (longer) than the length of the longest side of the body portion 81 of the adjustment portion 72 or the length of the tie metal piece 74 in the longitudinal direction.
[5.頂部繫帶之使用及收納] 且說，兒童座椅1(圖1)於使用時，為兒童座椅本體2(圖2)之座位部11與靠背部12結合之使用狀態，且裝載於車輛之座位(未圖示)上。 [5. The use and storage of the top tie] In other words, when the child seat 1 ( FIG. 1 ) is in use, the child seat body 2 ( FIG. 2 ) is combined with the seat portion 11 and the back portion 12 , and is mounted on a vehicle seat (not shown).
此時，兒童座椅本體2中，如圖2所示，於座位部11與靠背部12之結合部分之左右方向之中央附近，形成前後方向貫通之貫通孔13。該貫通孔13為由靠背部12(圖4)之中央下表面46、左卡合內側面44LS、右卡合內側面44RS、及座位部11(圖3)之後中央上表面27S包圍之空間。又，貫通孔13中，緊固帶53(圖1)之一部分穿過靠背側帶插通孔47(圖4)及座位側帶插通孔28(圖3)之間。At this time, in the child seat body 2, as shown in FIG. The through hole 13 is a space surrounded by the central lower surface 46 of the backrest 12 ( FIG. 4 ), the left engaging inner surface 44LS, the right engaging inner surface 44RS, and the rear central upper surface 27S of the seat portion 11 ( FIG. 3 ). Moreover, in the through hole 13, a part of the fastening belt 53 (FIG. 1) passes between the back-side belt insertion hole 47 (FIG. 4) and the seat-side belt insertion hole 28 (FIG. 3).
貫通孔13之左右方向之長度，即左卡合內側面44LS及右卡合內側面44RS之間隔如上所述，作為一例，為約80[mm]。因此，貫通孔13之左右方向之長度大於(長於)調節部72之本體部81之寬度。又，貫通孔13之上下方向之長度，即中央下表面46及後中央上表面27S之間隔作為一例，為約40[mm]。因此，貫通孔13之上下方向之長度大於(長於)調節部72之本體部81之高度。The length in the left-right direction of the through hole 13 , that is, the interval between the left engaging inner surface 44LS and the right engaging inner surface 44RS is about 80 [mm] as an example as described above. Therefore, the length in the left-right direction of the through hole 13 is greater (longer) than the width of the main body portion 81 of the adjustment portion 72 . Also, the length in the vertical direction of the through hole 13 , that is, the distance between the central lower surface 46 and the rear central upper surface 27S is about 40 [mm] as an example. Therefore, the vertical length of the through hole 13 is greater (longer) than the height of the main body portion 81 of the adjustment portion 72 .
兒童座椅1於就座之嬰幼兒之體格較小，無法使用車輛之安全帶之情形時，藉由安全帶群4束縛該嬰幼兒。此時，兒童座椅1需要以充足之強度安裝於車輛，故使用車輛卡合部24(圖3等)及頂部繫帶5(圖1等)。When the child seat 1 is small in stature and cannot use the safety belt of the vehicle, the child seat 1 restrains the infant by means of the safety belt group 4 . At this time, the child seat 1 needs to be mounted on the vehicle with sufficient strength, so the vehicle engaging portion 24 (Fig. 3 etc.) and the top tether 5 (Fig. 1 etc.) are used.
車輛卡合部24如圖3等所示，設為向後方伸出之狀態，與組入於車輛側之座位之車輛側金屬件(未圖示)卡合。頂部繫帶5於繫帶金屬件74之前端部93卡合於設置於車輛之座位後方之車輛側金屬件(未圖示)後，調節調節部72相對於繫帶71之位置，成為對該繫帶71作用充足張力之狀態。藉此，兒童座椅1成為適當固定於車輛之狀態。以下，將該狀態稱為固定使用狀態。As shown in FIG. 3 and the like, the vehicle engaging portion 24 is set in a state protruding rearward, and is engaged with a vehicle side metal fitting (not shown) incorporated in a seat on the vehicle side. After the front end 93 of the top tether 5 is engaged with the vehicle side metal piece (not shown) arranged behind the seat of the vehicle after the front end 93 of the tether metal piece 74, the position of the adjusting portion 72 relative to the tether 71 is adjusted to become The frenulum 71 is in a state of sufficient tension. Thereby, the child seat 1 becomes the state fixed to a vehicle suitably. Hereinafter, this state is referred to as a stationary use state.
又，兒童座椅1於就座之嬰幼兒之體格較大，使用車輛之安全帶之情形時，無須固定於車輛，故不使用車輛卡合部24、安全帶群4及頂部繫帶5。以下，將該狀態稱為非固定使用狀態。In addition, the child seat 1 does not need to be fixed to the vehicle when the seated infant has a relatively large physique and uses the safety belt of the vehicle, so the vehicle engaging portion 24 , the safety belt group 4 and the top tether 5 are not used. Hereinafter, this state is referred to as a non-fixed use state.
此處，圖6係非固定使用狀態之兒童座椅本體2之前視圖。圖7係顯示圖6之A1-A2剖面之剖視圖。圖8係非固定使用狀態之兒童座椅本體2之後視圖。圖9係非固定使用狀態之俯視圖。Here, FIG. 6 is a front view of the child seat body 2 in an unfixed use state. FIG. 7 is a cross-sectional view showing the section A1-A2 of FIG. 6 . Fig. 8 is a rear view of the child seat body 2 in an unfixed use state. Fig. 9 is a top view of the non-fixed use state.
兒童座椅本體2為非固定使用狀態之情形時，頂部繫帶5首先以調節部72靠近繫帶71之相對前端側之方式調節。接著，頂部繫帶5之繫帶金屬件74、連接帶73、調節部72及該繫帶71之一部分自該前端側起自貫通孔13之後側向前側依序插通。此時，兒童座椅本體2中，可藉由使穿過靠背側帶插通孔47(圖4)及座位側帶插通孔28(圖3)之間之緊固帶53之一部分向右側或左側彎曲，而使調節部72等插通(圖8)。When the child seat body 2 is in a non-fixed use state, the top tether 5 is firstly adjusted so that the adjustment portion 72 is close to the opposite front end side of the tether 71 . Next, the tether metal piece 74 of the top tether 5 , the connecting belt 73 , the adjustment portion 72 and a part of the tether 71 are sequentially inserted from the front end side to the front side from the rear side of the through hole 13 . At this time, in the child seat body 2, a part of the fastening belt 53 passing through the back-side belt insertion hole 47 (FIG. 4) and the seat-side belt insertion hole 28 (FIG. 3) can be moved to the right side. Or the left side is bent, and the adjustment part 72 etc. are inserted (FIG. 8).
藉此，頂部繫帶5如圖7及圖8所示，於兒童座椅本體2之後側，繫帶71以自繫帶安裝部43沿靠背部12之背面下降，進入貫通孔13內之方式配置。又，頂部繫帶5於兒童座椅本體2之前側，如圖7及圖9所示，向貫通孔13之前方被拉出後，沿座位面21S上朝前方向行進，最終到達收納凹口26。Thereby, as shown in Figure 7 and Figure 8, the top tether 5 is on the rear side of the child seat body 2, and the tether 71 descends from the tether installation part 43 along the back of the backrest 12 and enters the through hole 13. configuration. In addition, the top tether 5 is on the front side of the child seat body 2, as shown in FIGS. 7 and 9, after being pulled out to the front of the through hole 13, it travels forward along the seat surface 21S, and finally reaches the storage recess. 26.
再者，頂部繫帶5之繫帶金屬件74、連接帶73、調節部72及該繫帶71之一部分(以下，將該等總稱為頂部繫帶末端部5F)收納於座位部11(圖2及圖3)之收納凹口26。此時，繫帶71以適當捲收剩餘部分之狀態，收納於收納凹口26。又，藉由將連接帶73適當撓曲，而將繫帶金屬件74及調節部72皆收納於收納凹口26內。Moreover, the tether metal fittings 74 of the top tether 5, the connection belt 73, the adjustment portion 72, and a part of the tether 71 (hereinafter, these are collectively referred to as the top tether end portion 5F) are accommodated in the seat portion 11 (Fig. 2 and Fig. 3) the accommodation notch 26. At this time, the tether 71 is stored in the storage notch 26 in a state where the remainder is properly rolled up. In addition, by appropriately bending the connection belt 73 , both the tie metal fitting 74 and the adjusting portion 72 are accommodated in the accommodation recess 26 .
順帶一提，實際之兒童座椅1係以覆蓋座位部11之座位面21S及收納凹口26、以及頂部繫帶5中位於貫通孔13前側之部分之方式，安裝外罩3(圖1)。By the way, the actual child seat 1 is equipped with the cover 3 so as to cover the seat surface 21S and the storage recess 26 of the seat portion 11, and the portion of the top tether 5 located on the front side of the through hole 13 (FIG. 1).
又，兒童座椅本體2為非固定使用狀態之情形時，將安全帶群4中之肩帶52之一部分收納於靠背部12之靠背移位部42之帶收納孔49(圖4)。再者，如圖9所示，安全帶群4中之胯帶51及搭扣54與頂部繫帶5之一部分，一起收納於座位部11之收納凹口26。順帶一提，車輛卡合部24(圖2等)向前方移位，成為不朝座位部11之後方突出之狀態。Also, when the child seat body 2 is in a non-fixed use state, part of the shoulder belt 52 of the safety belt group 4 is stored in the belt receiving hole 49 of the backrest shifting portion 42 of the backrest 12 ( FIG. 4 ). Furthermore, as shown in FIG. 9 , the crotch belt 51 and the buckle 54 of the safety belt group 4 and a part of the top tether 5 are stored in the receiving recess 26 of the seat portion 11 together. Incidentally, the vehicle engaging portion 24 (see FIG. 2 etc.) is displaced forward and is in a state where it does not protrude toward the rear of the seat portion 11 .
[6.效果等] 以上之構成中，本實施形態之兒童座椅1於兒童座椅本體2之座位部11設置收納凹口26，且於將該座位部11及靠背部12結合之狀態下，於兩者之邊界部分形成貫通孔13(圖2)。 [6. Effects, etc.] In the above configuration, the child seat 1 of the present embodiment is provided with a receiving notch 26 on the seat portion 11 of the child seat body 2, and in the state where the seat portion 11 and the back portion 12 are combined, a storage recess 26 is formed at the boundary between the two. Through-holes 13 are partially formed (FIG. 2).
兒童座椅本體2於不使用頂部繫帶5之非固定使用狀態下，將該頂部繫帶5自貫通孔13之後側向前側插通，將頂部繫帶末端部5F收納於收納凹口26(圖7及圖9)。When the child seat body 2 is in the non-fixed use state without using the top tether 5, the top tether 5 is inserted from the rear side to the front side of the through hole 13, and the top tether end portion 5F is stored in the storage notch 26 ( Figure 7 and Figure 9).
因此，兒童座椅1於非固定使用狀態下，可維持將頂部繫帶末端部5F收納於座位部11，且使繫帶71之根部側部分與兒童座椅本體2大致密接之狀態，即整齊之狀態。即，兒童座椅1可確實阻止頂部繫帶5垂下之狀態，或隨著車輛之行駛，該頂部繫帶5之調節部72等雜亂地到處移動而觸碰到與車輛內之各部分或乘客。Therefore, when the child seat 1 is used in a non-fixed state, the top tether end portion 5F can be stored in the seat portion 11, and the root side portion of the tether 71 can be kept in a state of approximately close contact with the child seat body 2, that is, neatly arranged. state. That is to say, the child seat 1 can surely prevent the top tether 5 from hanging down, or as the vehicle travels, the adjustment portion 72 of the top tether 5 moves around messily and touches various parts or passengers in the vehicle. .
尤其，座位部11中，座位面21S上，於成為就座之嬰幼兒之雙腳間之下側之部位，即無須支撐該嬰幼兒之身體之部位，設置有收納凹口26。因此，兒童座椅1中，即使於收納凹口26收納有頂部繫帶末端部5F，亦不會對就座之嬰幼兒帶來不適。In particular, in the seat portion 11, on the seat surface 21S, a receiving recess 26 is provided at a position below the feet of a seated infant, that is, a portion that does not need to support the infant's body. Therefore, even if the top tether end portion 5F is stored in the storage recess 26 in the child seat 1 , it does not cause discomfort to the seated infant.
又，座位部11中，於與安裝胯帶51之帶安裝部25之前側相鄰之部位，設置有收納凹口26(圖2及圖3等)。因此，兒童座椅本體2中，於非固定使用狀態下，可將用以束縛嬰幼兒之安全帶群4之一部分即胯帶51等、及用以將兒童座椅1固定於車輛之頂部繫帶5之一部分集中收納於收納凹口26(圖9)。藉此，兒童座椅1只要使保護者等將非固定使用狀態下皆不需要之安全帶群4及頂部繫帶5之一部分匯總收納於1處收納凹口26即可，可使其直觀地作業。Moreover, in the seat portion 11, a storage notch 26 is provided at a portion adjacent to the front side of the belt mounting portion 25 to which the crotch belt 51 is mounted (see FIGS. 2 and 3 , etc.). Therefore, in the child seat body 2, in the non-fixed use state, a part of the safety belt group 4 for restraining the infant, that is, the crotch belt 51, etc., and the top system for fixing the child seat 1 to the vehicle can be A part of the belt 5 is collectively stored in the storage notch 26 (FIG. 9). In this way, the child seat 1 only needs to allow the protector to store part of the safety belt group 4 and the top tether 5 that are not needed in the non-fixed use state in one storage notch 26, so that it can be intuitively Operation.
基於其他觀點來看，兒童座椅1中，亦考慮例如於靠背部12之後面側形成後部收納凹口(未圖示)，於該後部收納凹口收納頂部繫帶末端部5F之構成。然而，該構成中，為不與靠背部12內之安全帶群4等干涉而確保收納凹口之容積，需要增加靠背部12之前後長(即厚度)。又，該構成中，為維持收納有頂部繫帶末端部5F之狀態，亦需要設置可開閉之蓋，故有招致因構造複雜化或零件件數增加引起之成本上升之虞。From another point of view, in the child seat 1 , for example, a rear storage recess (not shown) is formed on the back surface side of the backrest 12 and the top tether end portion 5F is stored in the rear storage recess. However, in this configuration, in order to ensure the volume of the storage recess without interfering with the seat belt group 4 in the backrest 12, it is necessary to increase the front and back length (ie, thickness) of the backrest 12 . Also, in this configuration, an openable and closable cover is required to maintain the state in which the top tether end portion 5F is accommodated, which may lead to increased cost due to a complicated structure or an increase in the number of parts.
相對於此，本實施形態之兒童座椅1於座位部11之座位面21S中，於由朝上方向最突出之座位面頂部21ST自左右夾著之部位，設置有收納凹口26。因此，兒童座椅1可確保充足之深度，且確保用以使緊固帶53通過其下側之空間。又，由於兒童座椅1係收納凹口26相對於座位面21S朝下方向凹陷之空間，故可不設置蓋等，而藉由重力之作用，容易維持收納有頂部繫帶末端部5F等之狀態。On the other hand, in the child seat 1 of the present embodiment, in the seat surface 21S of the seat part 11, the storage recess 26 is provided at a portion sandwiched from the left and right by the seat surface top 21ST protruding most upward. Therefore, the child seat 1 can secure a sufficient depth, and also secure a space for the fastening belt 53 to pass through its lower side. Also, since the child seat 1 is a space in which the storage notch 26 is sunken downward relative to the seat surface 21S, no cover or the like may be provided, and the state in which the top tether end portion 5F and the like are stored is easily maintained by the action of gravity. .
再者，兒童座椅本體2中，於成為結合之座位部11及靠背部12之邊界之部位，形成貫通孔13(圖2等)。因此，兒童座椅1中，只要於座位部11及靠背部12之間以較大之間隙形成貫通孔13，即可形成用以將頂部繫帶5自靠背部12之後側向前側拉出之孔。藉此，兒童座椅1中，與另外設置用以使頂部繫帶5插通靠背部12或座位部11之孔之情形相比，可提高強度或提高設計之自由度。Furthermore, in the child seat body 2, a through-hole 13 is formed at a portion that becomes a boundary between the combined seat portion 11 and the back portion 12 (see FIG. 2, etc.). Therefore, in the child seat 1, as long as the through hole 13 is formed with a relatively large gap between the seat portion 11 and the back portion 12, a hole for pulling the top tether 5 from the rear side of the back portion 12 to the front side can be formed. hole. Thereby, in the child seat 1, compared with the case where a hole for inserting the top tether 5 through the backrest part 12 or the seat part 11 is provided separately, it is possible to increase the strength and increase the degree of freedom of design.
此外，靠背部12中，可使靠背側帶插通孔47(圖4)之左右方向之長度(作為一例，為約80[mm])充分大於(長於)緊固帶53之寬度(作為一例，為約25[mm])而構成。因此，兒童座椅1中，使頂部繫帶5之前端側插通貫通孔13時，可容易使緊固帶53向左右方向彎曲，可容易使調節部72等插通(圖8)。In addition, in the backrest part 12, the length (as an example, about 80 [mm]) in the left-right direction of the backrest side belt insertion hole 47 (FIG. 4) can be sufficiently larger (longer) than the width of the fastening belt 53 (as an example). , is about 25 [mm]) and constituted. Therefore, in the child seat 1, when the front end side of the top tether 5 is inserted through the through hole 13, the fastening belt 53 can be easily bent in the left and right directions, and the adjustment portion 72 can be inserted easily ( FIG. 8 ).
根據以上之構成，本實施形態之兒童座椅1於兒童座椅本體2之座位部11設置收納凹口26，將該座位部11及靠背部12結合時，於兩者之邊界部分形成貫通孔13。兒童座椅本體2於不使用頂部繫帶5之非固定使用狀態下，將該頂部繫帶5自貫通孔13之後側向前側插通，將頂部繫帶末端部5F收納於收納凹口26。因此，兒童座椅1於非固定使用狀態下時，可維持將頂部繫帶末端部5F收納於座位部11，且使繫帶71之根部側部分與兒童座椅本體2大致密接之狀態。According to the above structure, the child seat 1 of the present embodiment is provided with the receiving recess 26 in the seat portion 11 of the child seat body 2, and when the seat portion 11 and the back portion 12 are combined, a through hole is formed at the boundary between the two. 13. When the child seat body 2 is in an unfixed use state without the top tether 5 , the top tether 5 is inserted through the through hole 13 from the rear side to the front side, and the top tether end portion 5F is stored in the storage notch 26 . Therefore, when the child seat 1 is in the non-fixed use state, the top tether end portion 5F can be stored in the seat portion 11 and the root side portion of the tether 71 can be kept in close contact with the child seat body 2 .
