Description
本發明係關於一種兒童座椅，例如係較佳適用於安裝於汽車而使用之情形者。 The present invention relates to a child seat, which is preferably suitable for use when installed in a car.
先前，兒童座椅中，例如於嬰幼兒等搭乘汽車等車輛之情形時，安裝於該車輛之座位而使用者得到廣泛普及。又，於大多兒童座椅，設置有用以將就座之幼兒束縛於該兒童座椅上之安全帶。該安全帶例如藉由將設置於幼兒之兩肩附近之肩帶等連接於設置於該幼兒之胯附近之胯帶，而可將該幼兒良好地束縛於該兒童座椅上。 In the past, child seats were installed on the seats of vehicles such as automobiles and were widely used when infants and young children were riding in the vehicles. In addition, most child seats are provided with safety belts for restraining the seated infant to the child seat. The safety belt can securely restrain the infant to the child seat by, for example, connecting shoulder straps disposed near both shoulders of the infant to a crotch belt disposed near the crotch of the infant.
此種安全帶於不使用時，因重力之作用成為肩帶垂下之狀態。因此，兒童座椅中，使嬰幼兒就座時，需暫時提起該肩帶，或者使嬰幼兒就座後，將該肩帶自該嬰幼兒之背後拉出等繁瑣之作業。 When this type of safety belt is not in use, the shoulder straps hang down due to gravity. Therefore, in a child seat, when an infant is seated, it is necessary to temporarily lift the shoulder strap, or after the infant is seated, it is necessary to pull the shoulder strap out from behind the infant, such as cumbersome operations.
因此，作為兒童座椅，提案有以下者：藉由於肩帶之下側，設置向前斜上方突出之棒狀之彈起部，於不使用安全帶時將該肩帶彈起，而容易進行嬰幼兒之上下車。 Therefore, as a child seat, the following is proposed: By providing a rod-shaped pop-up portion protruding forward and upward obliquely on the underside of the shoulder strap, the shoulder strap can be easily lifted when the seat belt is not used. Infants and young children will get off the bus.

[專利文獻] [Patent Document]
專利文獻1：日本專利特開2019-26147號公報(圖1等) Patent Document 1: Japanese Patent Application Laid-Open No. 2019-26147 (Figure 1, etc.)
但，該構成之兒童座椅中，即使藉由彈起部將肩帶向上方彈起，左右方向之間隔亦與束縛時大致同等，故與嬰幼兒之頭部干涉之可能性較高。因此，兒童座椅中，有於嬰幼兒上下車時，需將肩帶朝左右擴展等繁瑣之作業之問題。 However, in the child seat with this structure, even if the shoulder strap is bounced upward by the pop-up part, the distance in the left and right directions is almost the same as when it is restrained, so the possibility of interference with the head of the infant is high. Therefore, there is a problem with child seats that requires cumbersome operations such as extending the shoulder straps to the left and right when infants and young children get in and out of the car.
本發明係考慮以上之點而完成者，欲提案一種可容易進行嬰幼兒之上下車之兒童座椅。 The present invention was made in consideration of the above points, and it is intended to propose a child seat that can easily allow infants and young children to get on and off the vehicle.
為解決該問題，本發明之兒童座椅中，設置：靠背部支持體，其於嬰幼兒就座之情形時，支撐該嬰幼兒之背部；插通孔，其設置於靠背部支持體之就座之嬰幼兒之肩部附近，貫通該靠背部支持體；帶，其插通插通孔，將嬰幼兒之背部束縛於靠背部支持體；彈性體，其自靠背部支持體之插通孔附近向嬰幼兒就座之側突設，可彈性變形；及帶連動部，其於使表示沿帶之長度方向之假想中心線之帶假想中心線以自嬰幼兒觀察之前側朝向左右方向之外側之方式，相對於表示沿彈性體之長度方向之假想中心軸之彈性體軸線傾斜之狀態下，使帶與彈性體連動。 In order to solve this problem, the child seat of the present invention is provided with: a backrest support body, which supports the back of the infant when the infant is seated; and an insertion hole, which is provided on the backrest support body. Near the shoulders of the infant and young child in the seat, it penetrates the backrest support body; the strap is inserted into the insertion hole to bind the infant's back to the backrest support body; the elastic body is inserted into the insertion hole of the backrest support body A protruding part is provided nearby toward the side where the infant is seated and is elastically deformable; and a belt linking part is configured so that the imaginary center line of the belt indicating the imaginary center line along the length direction of the belt is oriented from the front side when viewed by the infant toward the outside in the left and right direction. In this way, the belt and the elastic body are linked together in a state where they are tilted relative to the axis of the elastic body representing an imaginary central axis along the length direction of the elastic body.
本發明可藉由帶連動部，於使帶中心線相對於彈性體軸線傾斜之狀態下，使彈性體與帶連通。因此，本發明於將彈性體相對於靠背部支持體朝向嬰幼兒之前側之方式設置之情形時，可設為將帶之前側向左右方向之外側展開之狀態。再者，本發明於緊固帶之情形時，可使彈性體彈性變形，使該帶變形為配合嬰幼兒之身體之形狀而良好地束縛。 The present invention can connect the elastic body and the belt through the belt linking part in a state where the center line of the belt is inclined relative to the axis of the elastic body. Therefore, in the present invention, when the elastic body is arranged toward the front side of the infant with respect to the backrest support, the belt front side can be set in a state where the belt front side is deployed outward in the left-right direction. Furthermore, the present invention can elastically deform the elastic body when fastening the belt, so that the belt can be deformed to fit the shape of the infant's body and be well restrained.
根據本發明，可實現能容易進行嬰幼兒之上下車之兒童座椅。 According to the present invention, it is possible to realize a child seat in which infants and young children can easily get on and off the vehicle.

各帶插通孔41分別位於頸部對向部位32N之左右兩側，即就座之嬰幼兒之兩肩附近，供安全帶群4中之一部分帶(細節於下文敘述)插通。為方便說明，以下，亦將帶插通孔41簡稱為插通孔。各帶收納孔42位於帶插通孔41之下側。該帶收納孔42形成於上下方向上自帶插通孔41附近到達靠背支持部32之下端附近之較大範圍內。 Each belt insertion hole 41 is respectively located on the left and right sides of the neck-facing portion 32N, that is, near the shoulders of the seated infant, for inserting some of the belts in the safety belt group 4 (details will be described below). For convenience of explanation, below, the belt insertion hole 41 will also be referred to as an insertion hole for short. Each belt storage hole 42 is located below the belt insertion hole 41 . The belt storage hole 42 is formed in a wide range in the vertical direction from the vicinity of the belt insertion hole 41 to the vicinity of the lower end of the back support portion 32 .
各彈簧構件安裝孔43設置於與帶插通孔41之左右各者之外側相鄰之位置。該彈簧構件安裝孔43自前側觀察之形狀為長方形狀，以隨著自靠背支持部32之前面32F朝後方向行進而向下方行進之方式傾斜。 Each spring member mounting hole 43 is provided adjacent to the outer side of the left and right belt insertion holes 41 . The shape of the spring member mounting hole 43 is a rectangular shape when viewed from the front side, and is inclined downward as it proceeds in the rear direction from the front surface 32F of the back support portion 32 .
卡合機構部33(圖4)由2個軸導件51、卡合軸52、操作傳遞部53、鉤掛部54、彈推部55及軸連動體56等構成。各軸導件51於靠背支持部32之後面之左右各者，朝後方向立設於帶插通孔41及彈簧構件安裝孔43之間。該軸導件51形成為前後方向較長，上下方向較短，左右方向較薄之板狀，於後邊之中央附近形成有朝前方向細長挖掘之槽部51D。 The engagement mechanism part 33 (Fig. 4) is composed of two shaft guides 51, an engagement shaft 52, an operation transmission part 53, a hook part 54, a push part 55, a shaft linkage body 56, and the like. Each shaft guide 51 is erected on the left and right behind the backrest support part 32 in the rearward direction between the belt insertion hole 41 and the spring member mounting hole 43 . The shaft guide 51 is formed in a plate shape that is long in the front-rear direction, short in the up-down direction, and thin in the left-right direction, and has a groove portion 51D that is elongated and dug forward in the vicinity of the center of the rear side.
卡合軸52為具有充足長度之細長之圓柱狀之金屬構件。該 卡合軸52分別***至左右之軸導件51之槽部51D，成為使中心軸沿左右方向之姿勢。因此，卡合軸52於被施加外力之情形時，於槽部51D內，幾乎不於上下方向移位，而可朝前後方向移位。換言之，卡合軸52藉由軸導件51限制上下方向之移位，另一方面，可容易朝前後方向移位。 The engaging shaft 52 is an elongated cylindrical metal member with sufficient length. the The engaging shafts 52 are respectively inserted into the groove portions 51D of the left and right shaft guides 51 to assume an attitude in which the central axis is aligned in the left-right direction. Therefore, when an external force is applied to the engagement shaft 52 , the engagement shaft 52 is hardly displaced in the up-down direction within the groove portion 51D, but can be displaced in the front-rear direction. In other words, the engagement shaft 52 is restricted from being displaced in the up-down direction by the shaft guide 51, but can be easily displaced in the front-rear direction.
操作傳遞部53整體構成為上下方向細長之棒狀。該操作傳遞部53於頭保護部31及靠背支持部32之後側之左右方向之中央附近，遍及靠背移位部14之上側之大致一半之範圍配置。又，操作傳遞部53由頭保護部31及靠背支持部32可移動地支持，於維持前後方向及左右方向之位置不變之狀態下，可朝上下方向於特定之範圍內移位。 The entire operation transmitting portion 53 is configured in a rod shape that is elongated in the vertical direction. The operation transmission part 53 is disposed near the center of the left-right direction on the rear side of the head protection part 31 and the backrest support part 32 and covers approximately half of the upper side of the backrest shift part 14. In addition, the operation transmission part 53 is movably supported by the head protection part 31 and the backrest support part 32, and can be displaced in a specific range in the up and down direction while maintaining the position in the front-rear direction and the left-right direction.
鉤掛部54為與梯形之外周部分類似之形狀，保護者可用指尖鉤住而朝上方向施加力。該鉤掛部54安裝於操作傳遞部53之上端，且構成為可相對於該操作傳遞部53以沿左右方向之旋動軸為中心旋動。 The hooking portion 54 has a shape similar to the outer peripheral portion of a trapezoid, and the protector can hook it with his fingertips to apply force in the upward direction. The hook portion 54 is mounted on the upper end of the operation transmission portion 53 and is configured to be rotatable relative to the operation transmission portion 53 about a rotation axis in the left-right direction.
彈推部55為沿上下方向之螺旋彈簧，配置於操作傳遞部53之下側。該彈推部55之上端連接於操作傳遞部53，下端連接於靠背支持部32，且自自然狀態稍微伸展。因此，彈推部55將操作傳遞部53始終朝下方向彈推。 The push portion 55 is a coil spring along the up and down direction, and is disposed below the operation transmission portion 53 . The upper end of the push part 55 is connected to the operation transmission part 53, the lower end is connected to the back support part 32, and is slightly extended from the natural state. Therefore, the urging portion 55 always urges the operation transmitting portion 53 downward.
軸連動體56設置於操作傳遞部53之下端附近之後側，可與該操作傳遞部53一體於上下方向移位。該軸連動體56整體形成為長方體狀，且穿設有於左右方向貫通之插通孔56H。插通孔56H沿連結前上側與後下側之傾斜方向形成，插通有卡合軸52。 The shaft linkage body 56 is provided on the rear side near the lower end of the operation transmission part 53 and is displaceable in the vertical direction integrally with the operation transmission part 53 . The shaft linking body 56 is formed into a rectangular parallelepiped shape as a whole, and has an insertion hole 56H penetrating in the left and right directions. The insertion hole 56H is formed along the inclined direction connecting the front upper side and the rear lower side, and the engaging shaft 52 is inserted therethrough.
根據該構成，卡合機構部33於未操作鉤掛部54之情形時，藉由彈推部55之作用，使操作傳遞部53及軸連動體56於可移位之範圍內位於下側。此時，卡合軸52於軸連動體56之插通孔56H內位於前上側，且 位於軸導件51之槽部51D內之前側。即，卡合機構部33成為圖4所示之狀態。 According to this structure, when the hook portion 54 is not operated, the engagement mechanism portion 33 uses the action of the push portion 55 to position the operation transmitting portion 53 and the shaft linking body 56 on the lower side within the displaceable range. At this time, the engaging shaft 52 is located on the front and upper side in the insertion hole 56H of the shaft linkage body 56, and It is located on the front side inside the groove portion 51D of the shaft guide 51 . That is, the engagement mechanism part 33 is in the state shown in FIG. 4 .
另一方面，若由保護者對鉤掛部54施加朝上方向之力，則卡合機構部33與該鉤掛部54連動，操作傳遞部53及軸連動體56朝上方向移位。此時，卡合軸52於軸連動體56之插通孔56H內移動而位於後下側，且於軸導件51之槽部51D內移動而位於後側。 On the other hand, when the protector applies an upward force to the hook portion 54, the engagement mechanism portion 33 is linked to the hook portion 54, and the operation transmission portion 53 and the shaft linking body 56 are displaced upward. At this time, the engaging shaft 52 moves in the insertion hole 56H of the shaft linkage body 56 to be located on the rear lower side, and moves in the groove portion 51D of the shaft guide 51 to be located on the rear side.
其後，若對鉤掛部54施加力，則卡合機構部33藉由彈推部55之作用，將操作傳遞部53向下方向拉伸，使該操作傳遞部53及軸連動體56於可移位之範圍內位於下側。藉此，卡合軸52於軸連動體56之插通孔56H內再次位於前上側，且位於軸導件51之槽部51D內之前側。 Thereafter, when a force is applied to the hooking part 54, the engagement mechanism part 33 pulls the operation transmission part 53 downward through the action of the push part 55, so that the operation transmission part 53 and the shaft linking body 56 are moved in the downward direction. The shiftable range is located on the lower side. Thereby, the engaging shaft 52 is located on the front and upper side again in the insertion hole 56H of the shaft linkage body 56 and is located on the front side in the groove portion 51D of the shaft guide 51 .
即，卡合機構部33根據是否對鉤掛部54施加朝向上方向之力，可使操作傳遞部53及軸連動體56於上下方向移位，使卡合軸52於槽部51D內於前後方向移位。 That is, the engagement mechanism part 33 can displace the operation transmission part 53 and the shaft linkage body 56 in the up and down direction according to whether an upward force is applied to the hook part 54, so that the engagement shaft 52 can move forward and backward in the groove part 51D. direction shift.
靠背部12(圖2)於其製造時，使靠背移位部14自靠背基體部13之前側向後方移位而抵接。再者，靠背部12使靠背移位部14之卡合機構部33之軸導件51或軸連動體56等進入靠背基體部13之靠背基體前面孔23內。此時，靠背移位部14藉由使未圖示之導軌靠近或抵接於滑軌24之左右，而限制相對於靠背基體部13於左右方向移動。 When the backrest portion 12 ( FIG. 2 ) is manufactured, the backrest displacement portion 14 is displaced from the front side to the backrest base portion 13 to come into contact with the backrest portion 12 ( FIG. 2 ). Furthermore, the backrest portion 12 allows the shaft guide 51 or the shaft linkage body 56 of the engagement mechanism portion 33 of the backrest displacement portion 14 to enter the backrest base front hole 23 of the backrest base portion 13 . At this time, the backrest displacement portion 14 restricts the movement in the left and right directions relative to the backrest base portion 13 by causing the guide rails (not shown) to approach or contact the left and right sides of the slide rail 24 .
接著，靠背部12中，於靠背基體前面部22之後側，卡合軸52通過滑軌24之後側，且以通過軸導件51之槽部51D內及軸連動體56之插通孔56H內之方式插通。藉此，限制靠背移位部14相對於靠背基體部13於前後方向移動。 Next, in the backrest portion 12 , on the rear side of the backrest base front portion 22 , the engaging shaft 52 passes through the rear side of the slide rail 24 and passes through the groove portion 51D of the shaft guide 51 and the insertion hole 56H of the shaft linking body 56 way to get through. Thereby, the backrest displacement part 14 is restricted from moving in the front-back direction with respect to the backrest base part 13.
如此組裝之靠背部12於未操作卡合機構部33之鉤掛部54之情 形時，使卡合軸52位於槽部51D內之前側，且與滑軌24之某個卡合槽25卡合。藉此，靠背部12將靠背移位部14相對於靠背基體部13之位置固定。即，兒童座椅1可藉由靠背移位部14之頭保護部31，良好地保護就座之嬰幼兒之頭部。 The backrest portion 12 assembled in this way is in a state where the hook portion 54 of the engaging mechanism portion 33 is not operated. When the slide rail 24 is formed, the engaging shaft 52 is located on the front side of the groove portion 51D and engages with one of the engaging grooves 25 of the slide rail 24 . Thereby, the backrest portion 12 fixes the position of the backrest displacement portion 14 relative to the backrest base portion 13 . That is, the child seat 1 can well protect the head of the infant sitting in the seat through the head protection portion 31 of the backrest displacement portion 14 .
另一方面，靠背部12於將卡合機構部33之鉤掛部54朝上方向拉動時，成為使卡合軸52位於槽部51D內之後側，且自滑軌24之卡合槽25脫離之狀態。藉此，靠背移位部14可沿靠背基體部13之滑軌24於上下方向移位。 On the other hand, when the backrest portion 12 pulls the hook portion 54 of the engaging mechanism portion 33 in the upward direction, the engaging shaft 52 is positioned behind the groove portion 51D and is disengaged from the engaging groove 25 of the slide rail 24 state. Thereby, the backrest displacement part 14 can be displaced in the up and down direction along the slide rail 24 of the backrest base part 13 .
再者，靠背部12於釋放施加於鉤掛部54之力時，於該時點之靠背移位部14之位置或其最近之位置，使卡合軸52與滑軌24之卡合槽25卡合，而固定該靠背移位部14之位置。 Furthermore, when the backrest 12 releases the force exerted on the hook portion 54, the engagement shaft 52 is engaged with the engagement groove 25 of the slide rail 24 at the position of the backrest displacement portion 14 at that time point or its closest position. Close, and fix the position of the backrest displacement part 14.
如此，兒童座椅1可根據就座之嬰幼兒之體型，調節靠背移位部14相對於靠背基體部13之位置(高度)，將頭保護部31等匹配於適當之位置(高度)。 In this way, the child seat 1 can adjust the position (height) of the backrest displacement portion 14 relative to the backrest base portion 13 according to the body shape of the infant sitting there, and match the head protection portion 31 and the like to an appropriate position (height).
順帶一提，靠背部12成為靠背移位部14之靠背支持部32之前面32F雖大致朝向正面，但詳細而言係朝向稍微斜上側之狀態。即，前面32F成為如其之法線自前方向略微向斜上側傾斜之傾斜面。 Incidentally, the front surface 32F of the backrest support portion 32 of the backrest portion 12 that becomes the backrest shift portion 14 is generally facing the front, but in detail, it is facing slightly obliquely upward. That is, the front surface 32F is an inclined surface in which the normal line thereof is slightly inclined obliquely upward from the front direction.
[1-2.安全帶群及外罩之構成] [1-2. Composition of seat belt group and outer cover]
安全帶群4(圖1)由複數根帶或零件之組合而構成，其一部分安裝或組入於兒童座椅本體2。該安全帶群4由胯帶61、肩帶62(62L及62R)、緊固帶63等複數根帶、以及搭扣64、鎖舌65(65L及65R)及肩帶外罩66等零件構成。其中，胯帶61、肩帶62及緊固帶63之各帶藉由分別將纖維以特定之方式編織，而構成為具有特定寬度及厚度、且具有充分長度之帶狀，具 有柔軟性且具有充分之拉伸強度。 The seat belt group 4 (Fig. 1) is composed of a plurality of belts or parts, and a part of them is installed or integrated into the child seat body 2.

The shoulder straps 62 (62L and 62R) are installed on the left and right sides of the infant to connect the upper side of the shoulder and the outer side of the waist, and lock tongues 65 (65L and 65R) are inserted respectively. Furthermore, a shoulder strap cover 66 (66L and 66R) is inserted into each shoulder strap 62 respectively.
圖5顯示兒童座椅本體2之模式性剖視圖。將肩帶62L及62R自位於嬰幼兒之肩膀附近之靠背移位部14之帶插通孔41(圖3)分別拉入至靠背基體部13之內部。再者，肩帶62L及62R於靠背基體部13之內部，與1條緊固帶63連接。為方便說明，以下，亦將肩帶62簡稱為帶。 FIG. 5 shows a schematic cross-sectional view of the child seat body 2 . Pull the shoulder straps 62L and 62R respectively into the inside of the backrest base 13 from the strap insertion holes 41 (Fig. 3) of the backrest displacement part 14 located near the shoulders of the infant. Furthermore, the shoulder straps 62L and 62R are connected to a fastening strap 63 inside the backrest base portion 13 . For convenience of explanation, below, the shoulder strap 62 will also be referred to as a belt for short.
緊固帶63於靠背基體部13之內部向下方行進，自該靠背基體部13之下端附近拉出至外部。又，緊固帶63自座位部11之後端附近進入該座位部11之內部，朝前方行進，自該座位部11之前端附近向前方拉出。 The fastening belt 63 runs downward inside the backrest base portion 13 and is pulled out from near the lower end of the backrest base portion 13 to the outside. In addition, the fastening belt 63 enters the inside of the seat portion 11 from the vicinity of the rear end of the seat portion 11 , travels forward, and is pulled forward from the vicinity of the front end of the seat portion 11 .
再者，肩帶62及緊固帶63於靠背基體部13及座位部11之內部，以可沿長度方向滑動之方式插通。又，於座位部11之前端附近，設置有固定緊固帶63或解除固定之帶止擋件68。 Furthermore, the shoulder straps 62 and the fastening straps 63 are slidably inserted into the backrest base portion 13 and the seat portion 11 in a longitudinal direction. In addition, near the front end of the seat portion 11, a fastening belt 63 is provided or a belt stopper 68 for releasing the fastening belt is provided.
該安全帶群4於嬰幼兒就座之狀態下，以使肩帶62L及62R穿過該嬰幼兒之肩膀之上側或前側之方式配置，將鎖舌65L及65R組合後，***至搭扣64，進而將緊固帶63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於兒童座椅本體2之靠背部12，可使該嬰幼兒維持就座狀態。以下，將此種狀態稱為束縛狀態。 The seat belt group 4 is configured such that the shoulder straps 62L and 62R pass through the upper or front side of the infant's shoulders when the infant is seated. The lock tongues 65L and 65R are assembled and then inserted into the buckle 64 , and then pull out the fastening belt 63 forward. Thereby, the seat belt group 4 can restrain the infant's shoulders to the waist to the backrest 12 of the child seat body 2, thereby maintaining the infant in a seated state. Hereinafter, this state is called a bound state.
又，兒童座椅1中，例如體格較大之幼兒就座時，有不使用安全帶群4而使用車輛之安全帶之情形。此時，兒童座椅1中，藉由將肩 帶62及肩帶外罩66之一部分***帶收納孔42(圖3)，而可收納於靠背基體部13之內部。 Furthermore, when a large infant, for example, is seated in the child seat 1, the seat belt group 4 may not be used but the seat belt of the vehicle may be used. At this time, in child seat 1, by placing the shoulder A part of the strap 62 and the shoulder strap cover 66 is inserted into the strap storage hole 42 ( FIG. 3 ), and can be stored inside the backrest base 13 .
外罩3(圖1)為藉由布或海綿材等之組合，分割成各部分之構成，各自具有充足之柔軟性。又，外罩3分割成複數個部分，且構成為各部分可相對於兒童座椅本體2或後述之安全帶群4裝卸。 The outer cover 3 (Fig. 1) is composed of a combination of cloth or sponge materials and is divided into various parts, each of which has sufficient flexibility. Furthermore, the outer cover 3 is divided into a plurality of parts, and each part is configured to be attachable and detachable to the child seat body 2 or the seat belt group 4 described below.
[2.彈簧構件之構成] [2. Composition of spring components]
圖6A及圖6B分別係顯示彈簧構件70之整體之概略立體圖，且係顯示自互不相同之方向觀察之狀況。圖7係顯示彈簧構件70之整體之概略左側視圖。圖8係顯示圖7之A1-A2剖面之概略剖視圖。 FIGS. 6A and 6B are respectively schematic perspective views showing the entire spring member 70 when viewed from different directions. FIG. 7 is a schematic left side view showing the entire spring member 70 . FIG. 8 is a schematic cross-sectional view showing the A1-A2 section of FIG. 7 .
作為彈性體之彈簧構件70整體形成為細長之棒狀，成為沿假想之彈簧軸線X70(圖7)，以向上側突出之方式平緩彎曲之形狀。又，彈簧構件70例如為TPE(Thermoplastic elastomer：熱塑性樹脂橡膠彈性體)等樹脂材料之成形零件，根據被施加之外力而彈性變形。順帶一提，圖6A、圖6B及圖7皆顯示未對彈簧構件70施加外力之自然狀態之形狀。又，以下，亦將彈簧軸線X70稱為彈性體軸線。 The spring member 70 which is an elastic body is formed into an elongated rod shape as a whole, and has a shape that is gently curved so as to protrude upward along the imaginary spring axis X70 (Fig. 7). In addition, the spring member 70 is a molded part of a resin material such as TPE (Thermoplastic elastomer), and elastically deforms when an external force is applied. Incidentally, FIG. 6A , FIG. 6B and FIG. 7 all show the shape of the spring member 70 in its natural state when no external force is applied. In addition, below, the spring axis X70 will also be called an elastic body axis.
該彈簧構件70由佔前側之約5/6範圍之突出部71、與佔後側之約1/6範圍之***部72構成。突出部71如圖8所示，其剖面為大致橢圓形，前端附近較細，隨著朝後方行進逐漸變粗。又，突出部71之最後側之部分，即與***部72之邊界部分與其周圍相比，朝下方向及左右方向局部變粗。再者，突出部71中與***部72之邊界面即突出部側邊界面71S形成為平面狀，但其法線相對於彈簧軸線X70之切線傾斜約45度。 The spring member 70 is composed of a protruding portion 71 that occupies approximately 5/6 of the front side, and an insertion portion 72 that occupies approximately 1/6 of the rear side. As shown in FIG. 8 , the protruding portion 71 has a substantially oval cross-section, is thinner near the front end, and gradually becomes thicker as it proceeds toward the rear. In addition, the rearmost portion of the protruding portion 71, that is, the boundary portion with the insertion portion 72, is partially thicker in the downward and left-right directions than the surrounding portion. Furthermore, the protrusion side boundary surface 71S, which is the boundary surface between the protrusion portion 71 and the insertion portion 72, is formed in a planar shape, but its normal line is inclined at about 45 degrees with respect to the tangent line of the spring axis X70.
***部72由上側之柱狀部72A與下側之支持部72B構成。柱狀部72A整體形成為沿彈簧軸線X70之四角柱狀。支持部72B形成為以 與突出部側邊界面71S之後側相鄰之方式配置之長方體狀。 The insertion part 72 is composed of an upper columnar part 72A and a lower support part 72B. The columnar portion 72A is formed into a square columnar shape as a whole along the spring axis X70. The support portion 72B is formed to A rectangular parallelepiped shape arranged adjacent to the rear side of the protrusion side boundary surface 71S.
[3.肩帶外罩之構成] [3. Composition of shoulder strap cover]
圖9係顯示左側之肩帶外罩66L之整體之概略俯視圖。圖10係顯示圖9之B1-B2剖面之概略剖視圖。為方便起見，將圖9中之紙面近前側設為上方向，將其相反側設為下方向，又，將圖之下側設為前方向，將圖之上側設為後方向進行說明。 FIG. 9 is a schematic top view showing the entire left shoulder strap cover 66L. FIG. 10 is a schematic cross-sectional view showing the B1-B2 section in FIG. 9 . For the sake of convenience, the description will be made by assuming that the front side of the paper in FIG. 9 is the upward direction and the opposite side is the downward direction. Furthermore, the lower side of the figure is the front direction and the upper side of the figure is the rear direction.
順帶一提，右側之肩帶外罩66R(圖5)與左側之肩帶外罩66L左右對稱地構成。因此，以下，以左側之肩帶外罩66L為例進行說明，省略右側之肩帶外罩66R之說明。 Incidentally, the right shoulder strap cover 66R (Fig. 5) and the left shoulder strap cover 66L are configured to be symmetrical in left and right directions. Therefore, in the following description, the left shoulder strap cover 66L is used as an example, and the description of the right shoulder strap cover 66R is omitted.
作為帶連動部之肩帶外罩66由複數個布或帶狀之材料等柔軟構成，大致具有外罩本體部81及安裝帶部82。外罩本體部81整體構成為前後方向較長，左右方向較短，上下方向較薄之長方體狀或薄板狀。 The shoulder strap cover 66 as a belt linking part is made of a plurality of soft cloth or strip-shaped materials, and roughly has a cover body part 81 and an attachment belt part 82 . The cover body 81 is generally configured in a rectangular parallelepiped shape or a thin plate shape that is long in the front-rear direction, short in the left-right direction, and thin in the up-down direction.
又，外罩本體部81如圖10所示，於上下方向分成上層81U、中層81M及下層81L之3層。於該外罩本體部81之內部，於中層81M及下層81L之間，形成有帶插通空間83，且於上層81U及中層81M之間，形成有彈簧構件收容空間84。 In addition, as shown in FIG. 10 , the cover main body 81 is divided into three layers in the vertical direction: an upper layer 81U, a middle layer 81M, and a lower layer 81L. Inside the cover body 81, a belt insertion space 83 is formed between the middle layer 81M and the lower layer 81L, and a spring member receiving space 84 is formed between the upper layer 81U and the middle layer 81M.
帶插通空間83藉由將中層81M及下層81L之左邊部分及右邊部分封閉，另一方面，將前邊附近及後邊附近開放而形成，成為於前後方向貫通之空間。因此，外罩本體部81可使肩帶62L沿前後方向插通帶插通空間83。換言之，外罩本體部81可使肩帶62L沿表示帶插通空間83之長度方向之假想之帶插通軸線X83(圖9)，插通帶插通空間83。 The insertion space 83 is formed by closing the left and right portions of the middle floor 81M and the lower floor 81L, and opening the front and rear vicinity, thereby forming a space that penetrates in the front-rear direction. Therefore, the cover body portion 81 allows the shoulder strap 62L to be inserted into the strap insertion space 83 in the front-rear direction. In other words, the cover body 81 allows the shoulder strap 62L to be inserted into the belt insertion space 83 along the imaginary belt insertion axis X83 ( FIG. 9 ) indicating the length direction of the belt insertion space 83 .
作為彈性體收容空間之彈簧構件收容空間84中，中層81M及上層81U之左邊部分、右邊部分及前端部分封閉，另一方面，僅後 邊附近之左側之約1/3之範圍開放。又，於外罩本體部81，貫通中層81M及下層81L，且自上下夾住地分別安裝有子母扣85及86。子母扣85設置於左右方向之大致中央，且自後邊向前方行進前後長度之1/4左右之部位。子母扣86設置於左右方向之大致中央且前邊附近。 In the spring member storage space 84 as the elastic body storage space, the left part, the right part and the front end part of the middle layer 81M and the upper layer 81U are closed. On the other hand, only the rear part is closed. About 1/3 of the left side near the edge is open. Furthermore, snap-on buckles 85 and 86 are respectively attached to the cover body 81 so as to penetrate the middle layer 81M and the lower layer 81L and sandwich it from top to bottom. The snap button 85 is disposed approximately in the center in the left-right direction, and extends from the back to the front about 1/4 of the front-to-back length. The snap button 86 is provided approximately in the center in the left-right direction and near the front.
再者，於外罩本體部81，設置有將中層81M及上層81U縫合之接縫87及88。接縫87將外罩本體部81之左後頂點附近與子母扣86附近連結，形成相對於前後方向傾斜之直線狀。接縫88將外罩本體部81之較後邊之中央稍靠右之部位與子母扣86附近連結，形成與接縫87大致平行之直線狀。 Furthermore, the cover body 81 is provided with seams 87 and 88 for sewing the middle layer 81M and the upper layer 81U. The seam 87 connects the vicinity of the left rear apex of the cover body 81 and the vicinity of the snap buckle 86 to form a straight line inclined with respect to the front and rear direction. The seam 88 connects a portion slightly to the right of the rear center of the cover body 81 and near the snap button 86 to form a straight line substantially parallel to the seam 87 .
如此，彈簧構件收容空間84藉由接縫87及子母扣86限制左側之範圍，且藉由接縫88及子母扣85限制右側之範圍之一部分。因此，外罩本體部81可沿著接縫87，將彈簧構件70之突出部71收容於彈簧構件收容空間84。換言之，外罩本體部81可使彈簧構件70之長度方向沿著與接縫87大致平行之假想之彈簧構件收容軸線X84(圖9)，將該彈簧構件70收容於彈簧構件收容空間84。 In this way, the spring member receiving space 84 limits the range on the left side by the seam 87 and the snap button 86 , and limits a part of the range on the right side by the seam 88 and the snap button 85 . Therefore, the housing body 81 can accommodate the protruding portion 71 of the spring member 70 in the spring member receiving space 84 along the seam 87 . In other words, the cover body 81 can accommodate the spring member 70 in the spring member receiving space 84 by aligning the length direction of the spring member 70 along the imaginary spring member receiving axis X84 ( FIG. 9 ) that is substantially parallel to the seam 87 .
安裝帶部82(圖9)安裝於外罩本體部81之下層81L之下表面之後端附近。該安裝帶部82由後端附近回折之1條帶狀材料構成，藉由於後端附近設置接縫91，於後端側形成有安裝插通空間92。安裝插通空間92為於左右方向貫通之空間。又，於外罩本體部81之下層81L之下表面之較安裝帶部82前側之部分，設置有特定之防滑構件89(圖10)。 The attachment belt part 82 (FIG. 9) is attached near the rear end of the lower surface of the lower layer 81L of the cover body part 81. The mounting belt portion 82 is composed of a strip of material that is folded back near the rear end. By providing a seam 91 near the rear end, an mounting insertion space 92 is formed on the rear end side. The installation insertion space 92 is a space that penetrates in the left and right directions. In addition, a specific anti-slip member 89 is provided on a portion of the lower surface of the lower layer 81L of the cover body portion 81 in front of the mounting belt portion 82 (Fig. 10).
[4.肩帶外罩之安裝及彈簧構件之保持] [4. Installation of shoulder strap cover and retention of spring components]
接著，針對對靠背部12(圖2等)安裝肩帶外罩66、與利用彈簧構件70保持該肩帶外罩66及肩帶62分別進行說明。 Next, attachment of the shoulder strap cover 66 to the backrest portion 12 (see FIG. 2 and others) and holding the shoulder strap cover 66 and the shoulder strap 62 by the spring member 70 will be described.
靠背部12如上所述，於其製造時將靠背基體部13及靠背移位部14(圖3及圖4)組合。此時，靠背部12中，於左右各者，肩帶外罩66之安裝帶部82自靠背移位部14之前側插通帶插通孔41，進而將卡合軸52插通安裝插通空間92。 As mentioned above, the backrest base part 13 and the backrest displacement part 14 (FIGS. 3 and 4) are combined during manufacture of the backrest part 12. At this time, in the backrest portion 12 , on both the left and right sides, the mounting belt portion 82 of the shoulder belt cover 66 is inserted into the belt insertion hole 41 from the front side of the backrest displacement portion 14 , and the engaging shaft 52 is inserted into the mounting insertion space. 92.
又，靠背部12中，於組入安全帶群4(圖1及圖5)時，於左右各者，肩帶62插通肩帶外罩66之帶插通空間83(圖10)後，插通帶插通孔41。 Furthermore, when the seat belt group 4 (Fig. 1 and Fig. 5) is assembled in the backrest portion 12, the left and right shoulder straps 62 are inserted into the belt insertion space 83 (Fig. 10) of the shoulder strap outer cover 66, and then The passband is inserted into the through hole 41.
根據該構成，兒童座椅1中，肩帶62之前側相對於靠背部12於上下方向或左右方向移位而變形為各種形狀時，肩帶外罩66亦與該肩帶62一體變形，即，可使兩者連動。 According to this configuration, in the child seat 1 , when the front side of the shoulder belt 62 is displaced in the up-down direction or left-right direction relative to the backrest 12 and deformed into various shapes, the shoulder belt cover 66 is also deformed integrally with the shoulder belt 62 , that is, The two can be linked together.
順帶一提，如一面參照圖5一面說明，肩帶62可自肩帶插通孔41朝前方向拉出。另一方面，由於卡合軸52插通安裝插通空間92，故肩帶外罩66無法朝前方向拉出。 Incidentally, as explained with reference to FIG. 5 , the shoulder strap 62 can be pulled forward from the shoulder strap insertion hole 41 . On the other hand, since the engaging shaft 52 is inserted into the installation insertion space 92, the shoulder belt cover 66 cannot be pulled out in the forward direction.
例如，安裝有兒童座椅1之汽車於前進期間緊急制動之情形時，該兒童座椅1中，就座之嬰幼兒因慣性力之作用而與肩帶62一起欲朝前方向飛出。但，兒童座椅1中，由於肩帶外罩66之防滑構件89對與嬰幼兒之肩膀部分之間作用較大摩擦力，故可將該嬰幼兒維持就座之狀態。 For example, when a car equipped with a child seat 1 brakes suddenly while moving forward, an infant seated in the child seat 1 will fly out in the forward direction together with the shoulder strap 62 due to the inertial force. However, in the child seat 1, since the pair of anti-slip members 89 of the shoulder belt cover 66 exerts a large friction force on the shoulder portion of the infant, the infant can be maintained in a seated state.
此外，兒童座椅1中，於靠背部12之左右各者各安裝1個彈簧構件70(圖6A、圖6B等)。具體而言，彈簧構件70中，將突出部71之大部分自前端側收容於肩帶外罩66之彈簧構件收容空間84後，將***部72***靠背移位部14之彈簧構件安裝孔43。藉此，兒童座椅1中，可使彈簧構件70之突出部71與肩帶外罩66一體變形，即，使兩者連動。順帶一提，彈簧構件70可由保護者容易對彈簧構件安裝孔43裝卸。 In addition, in the child seat 1, one spring member 70 is installed on each of the left and right sides of the backrest portion 12 (Fig. 6A, Fig. 6B, etc.). Specifically, in the spring member 70 , after most of the protruding portion 71 is received in the spring member receiving space 84 of the shoulder belt cover 66 from the front end side, the insertion portion 72 is inserted into the spring member mounting hole 43 of the backrest shift portion 14 . Thereby, in the child seat 1, the protruding portion 71 of the spring member 70 and the shoulder belt cover 66 can be deformed integrally, that is, the two can be interlocked. Incidentally, the spring member 70 can be easily attached and detached from the spring member mounting hole 43 by a protector.
此處，圖11係以靠背部12之左前側部分為中心顯示之模式性剖視圖。又，靠背部中心線C12為表示靠背部12之左右方向之中心之假想直線。再者，肩帶中心線X62為沿肩帶62之長度方向之假想中心線。為方便說明，以下，亦將肩帶中心線X62稱為帶中心線。 Here, FIG. 11 is a schematic cross-sectional view showing the left front portion of the backrest portion 12 as the center. In addition, the backrest center line C12 is an imaginary straight line indicating the center of the backrest 12 in the left-right direction. Furthermore, the shoulder belt center line X62 is an imaginary center line along the length direction of the shoulder belt 62 . For convenience of explanation, below, the shoulder belt center line X62 will also be referred to as the belt center line.
彈簧構件70於未施加外力之自然狀態下，成為彈簧軸線X70於左右方向朝向中央，且於上下方向朝向前斜上方向之形狀。肩帶外罩66因於彈簧構件收容空間84收容有彈簧構件70，故彈簧構件收容軸線X84與彈簧軸線X70大體一致。又，肩帶外罩66因於帶插通空間83插通有肩帶62，故帶插通軸線X83與肩帶中心線X62大體一致。 In a natural state where no external force is applied, the spring member 70 has a shape in which the spring axis X70 is oriented toward the center in the left-right direction and is oriented obliquely forward and upward in the up-down direction. Since the shoulder strap outer cover 66 receives the spring member 70 in the spring member receiving space 84, the spring member receiving axis X84 is substantially consistent with the spring axis X70. In addition, since the shoulder strap 62 is inserted into the strap insertion space 83 of the shoulder strap outer cover 66, the strap insertion axis X83 is substantially consistent with the shoulder strap center line X62.
即，肩帶外罩66可維持使肩帶62之肩帶中心線X62相對於彈簧構件70之彈簧軸線X70始終傾斜之狀態。藉此，兒童座椅1中，於未對彈簧構件70施加外力之情形時，為以下之狀態，即，於水平面上，使彈簧軸線X70沿前後方向，使肩帶中心線X62之前側向離開靠背部中心線C12之方向傾斜。 That is, the shoulder belt cover 66 can maintain a state in which the shoulder belt center line X62 of the shoulder belt 62 is always inclined relative to the spring axis X70 of the spring member 70 . Therefore, in the child seat 1 , when no external force is applied to the spring member 70 , the child seat 1 is in the following state, that is, on the horizontal plane, the spring axis X70 is moved forward and backward in the forward and backward directions, and the shoulder strap center line X62 is laterally separated from the front. The backrest is tilted in the direction of center line C12.
於是，兒童座椅1中，如圖12A及圖12B所示，於未使用肩帶群4之狀態下，使左側之肩帶62L等之前側部分位於較後側更靠左上側，且使右側之肩帶62R等之前側部分位於較後側更靠右上側。換言之，兒童座椅1中，左右之肩帶62等成為如隨著朝前側行進而朝向斜上方向，且朝左右方向之外側打開之形狀。以下，將該狀態稱為非束縛狀態。 Therefore, in the child seat 1, as shown in FIGS. 12A and 12B, when the shoulder strap group 4 is not used, the front side portion such as the left shoulder strap 62L is positioned to the upper left side of the rear side, and the right side is positioned The front part of the shoulder strap 62R is located further to the upper right side than the rear side. In other words, in the child seat 1 , the left and right shoulder straps 62 and the like are formed in a shape such that they are directed obliquely upward as they travel toward the front side, and are opened outward in the left-right direction. Hereinafter, this state is called an unbound state.
另一方面，兒童座椅1設為緊固安全帶之束縛狀態之情形時，如圖5所示，於組合左右之鎖舌65L及65R後***至搭扣64，進而將緊固帶63向前方拉出。 On the other hand, when the child seat 1 is set to the restrained state of fastening the seat belt, as shown in FIG. 5 , after combining the left and right lock tongues 65L and 65R, insert them into the buckle 64 , and then push the fastening belt 63 toward the buckle 64 . Pull out front.
此時，兒童座椅1中，如圖13A及圖13B所示，肩帶62及肩 帶外罩66之前側部分被拉向左右之中央。伴隨於此，各彈簧構件70自肩帶外罩66經由彈簧構件收容空間84承受力，成為以隨著朝前側行進而向左右之內側且下側撓曲之方式變形之形狀。 At this time, in the child seat 1, as shown in Figures 13A and 13B, the shoulder straps 62 and shoulder The front side portion of the belt cover 66 is pulled toward the left and right center. Along with this, each spring member 70 receives a force from the shoulder strap cover 66 through the spring member receiving space 84 and becomes a shape deformed so as to deflect inwardly and downwardly on the left and right sides as it travels forward.
[5.效果等] [5. Effects, etc.]
以上之構成中，本實施形態之兒童座椅1於左右各者，彈簧構件70之***部72***設置於靠背部12之靠背移位部14之彈簧構件安裝孔43。又，兒童座椅1於左右各者，肩帶62插通肩帶外罩66之帶插通空間83，且各彈簧構件70之突出部71收容於彈簧構件收容空間84。 In the above structure, in the child seat 1 of this embodiment, the insertion portion 72 of the spring member 70 is inserted into the spring member mounting hole 43 provided in the backrest displacement portion 14 of the backrest portion 12 on both the left and right sides. In addition, in the child seat 1 on both left and right sides, the shoulder belt 62 is inserted into the belt insertion space 83 of the shoulder belt cover 66 , and the protruding portion 71 of each spring member 70 is accommodated in the spring member receiving space 84 .
各彈簧構件70成為使突出部71之前端於左右方向朝向大致中央之狀態(圖11及圖12A)。另一方面，肩帶外罩66使收容有突出部71之彈簧構件收容空間84之彈簧構件收容軸線X84相對於帶插通軸線X83傾斜(圖9及圖11)。 Each spring member 70 is in a state in which the front end of the protruding portion 71 is directed toward the substantially center in the left-right direction (Fig. 11 and Fig. 12A). On the other hand, the shoulder belt cover 66 inclines the spring member storage axis X84 of the spring member storage space 84 in which the protrusion 71 is accommodated relative to the belt insertion axis X83 (Figs. 9 and 11).
因此，兒童座椅1於非束縛狀態(圖12A及圖12B)下，成為彈簧構件70之前端於左右方向朝向大致中央之狀態，可以隨著朝前方行進而朝左右方向之外側擴展之方式支持肩帶外罩66及肩帶62。藉此，兒童座椅1可不使保護者進行提起肩帶62等並將之朝左右擴展之作業，又，可不使肩帶62等與嬰幼兒之頭部干涉，而使之容易且順利地上下車。 Therefore, in the unrestrained state (Fig. 12A and Fig. 12B), the child seat 1 is in a state where the front end of the spring member 70 is directed toward the substantially center in the left-right direction, and can be supported in such a manner that it expands outward in the left-right direction as it travels forward. Shoulder strap cover 66 and shoulder strap 62 . Thereby, the child seat 1 does not require the protector to lift up the shoulder straps 62 and the like and extend them left and right, and the child seat 1 does not cause the shoulder straps 62 and the like to interfere with the infant's head, making it easy and smooth to get in and out of the car. .
又，兒童座椅1中，於束縛狀態(圖13A及圖13B)下，成為使肩帶62等之前側被拉向左右之中央之狀態，對應於此，使彈簧構件70之前端向左右之中央側且下側撓曲。因此，兒童座椅1與不使用彈簧構件70之先前之兒童座椅(未圖示)同樣，可使安全帶群4適當密接於嬰幼兒之身體，可將該嬰幼兒良好地維持就座狀態。 In the child seat 1, in the restrained state (Fig. 13A and Fig. 13B), the front sides of the shoulder straps 62 and the like are pulled toward the center of the left and right. Correspondingly, the front ends of the spring members 70 are pulled toward the center of the left and right sides. The central and lower sides are deflected. Therefore, the child seat 1, like the previous child seat (not shown) that does not use the spring member 70, can make the seat belt group 4 closely contact the body of the infant and the infant, and can maintain the infant in a good sitting position. .
然而，作為兒童座椅，亦考慮藉由與本實施形態之兒童座 椅1不同之構成，而將肩帶62等之前側朝左右擴展。作為其一例，考慮如下之構成：肩帶外罩66(圖9)中，以使彈簧構件收容軸線X84與帶插通軸線X83平行之方式，形成彈簧構件收容空間84，使彈簧構件70之前端相對於靠背移位部14朝向左右方向之外側。 However, as a child seat, it is also considered to use a child seat similar to the child seat of this embodiment. The chair 1 has a different structure, and the front side of the shoulder straps 62 and the like is extended sideways to the left and right. As an example, consider a configuration in which the spring member accommodating space 84 is formed in the shoulder belt cover 66 (Fig. 9) so that the spring member accommodating axis X84 is parallel to the belt insertion axis X83, and the front ends of the spring member 70 are opposed to each other. The backrest shift portion 14 faces outward in the left-right direction.
圖14係比較用之兒童座椅101之與圖11對應之模式性剖視圖。該兒童座椅1成為於帶插通孔41與卡合機構部33之間配置彈簧構件安裝孔43，且以使後端部朝向後斜內側之方式配置之構成。 FIG. 14 is a schematic cross-sectional view corresponding to FIG. 11 of the child seat 101 for comparison. The child seat 1 is configured such that a spring member mounting hole 43 is disposed between the belt insertion hole 41 and the engagement mechanism portion 33, and the rear end portion is directed obliquely inward.
一般而言，兒童座椅中，配合嬰幼兒之肩寬等，必然決定帶插通孔41之左右方向之位置。又，兒童座椅中，靠背部12(圖3及圖4)中，可調整靠背移位部14相對於靠背基體部13之位置(高度)，且為確保需要之強度，卡合機構部33為某程度之大小。 Generally speaking, in a child seat, the position of the belt insertion hole 41 in the left and right directions must be determined according to the shoulder width of the infant. In addition, in the child seat, the position (height) of the backrest displacement portion 14 relative to the backrest base portion 13 can be adjusted in the backrest portion 12 (Fig. 3 and Fig. 4), and in order to ensure the required strength, the engagement mechanism portion 33 to a certain extent.
於是，如兒童座椅101般之構成中，由於彈簧構件安裝孔43無論如何皆與卡合機構部33干涉，故導致難以順利調節靠背移位部14相對於靠背基體部13之位置(高度)，或確保充分之強度。 Therefore, in a structure like the child seat 101, since the spring member mounting hole 43 interferes with the engagement mechanism part 33 anyway, it becomes difficult to smoothly adjust the position (height) of the backrest displacement part 14 relative to the backrest base part 13. , or ensure sufficient strength.
圖15係比較用之兒童座椅201之與圖11及圖14對應之模式性剖視圖。該兒童座椅201與兒童座椅1同樣，相對於帶插通孔41，於左右方向之外側配置有彈簧構件安裝孔43，但使該彈簧構件安裝孔43之後端部朝向後斜內側。 FIG. 15 is a schematic cross-sectional view corresponding to FIGS. 11 and 14 of the child seat 201 for comparison. Like the child seat 1 , this child seat 201 has a spring member mounting hole 43 disposed outside the belt insertion hole 41 in the left-right direction, but the rear end of the spring member mounting hole 43 faces obliquely inward.
如該兒童座椅201般之構成中，於欲使彈簧構件70以適當角度傾斜之情形時，會導致彈簧構件安裝孔43與帶插通孔41干涉，或該彈簧構件70與頭保護部31之保護材31B干涉。 In the structure of the child seat 201, when the spring member 70 is tilted at an appropriate angle, the spring member mounting hole 43 and the belt insertion hole 41 may interfere, or the spring member 70 and the head protection part 31 may interfere. The protective material 31B interferes.
如此，使彈簧構件70之彈簧軸線X70相對於前後方向傾斜之情形時，如兒童座椅101及201般，有彈簧構件安裝孔43與卡合機構部 33或帶插通孔41干涉，或該彈簧構件70與保護材31B干涉之虞。 In this way, when the spring axis X70 of the spring member 70 is tilted relative to the front-rear direction, like the child seats 101 and 201, there is a spring member mounting hole 43 and an engaging mechanism part. 33 may interfere with the insertion hole 41 or the spring member 70 may interfere with the protective material 31B.
相對於此，本實施形態之兒童座椅1如圖11所示，將彈簧構件安裝孔43相對於帶插通孔41配置於左右方向之外側，且使其後端部朝向左右方向之中央。 On the other hand, in the child seat 1 of this embodiment, as shown in FIG. 11 , the spring member mounting hole 43 is arranged outside the belt insertion hole 41 in the left-right direction, and its rear end is directed toward the center in the left-right direction.
藉此，兒童座椅1可確實避免使彈簧構件安裝孔43與卡合機構部33或帶插通孔41干涉，或使彈簧構件70與頭保護部31之保護材31B干涉。又，由於兒童座椅1只要將彈簧構件安裝孔43設為朝向左右之中央之孔即可，故可於左右方向上，將佔有範圍抑制為最小限度。 Thereby, the child seat 1 can reliably prevent the spring member mounting hole 43 from interfering with the engagement mechanism portion 33 or the belt insertion hole 41 , or the spring member 70 with the protective material 31B of the head protection portion 31 from interfering. In addition, since the child seat 1 only needs to make the spring member mounting hole 43 a hole facing the left and right center, the occupying range in the left and right directions can be suppressed to a minimum.
此外，兒童座椅1中，於肩帶外罩66，使彈簧構件收容軸線X84相對於帶插通軸線X83傾斜(圖9)。因此，兒童座椅1於不使用安全帶群4時，既可將彈簧構件70設為朝向左右方向之中央之狀態，且將肩帶62等之前側向左右之外側拉開。 Furthermore, in the child seat 1, the spring member accommodation axis X84 of the shoulder belt cover 66 is inclined relative to the belt insertion axis X83 (Fig. 9). Therefore, when the seat belt group 4 is not used in the child seat 1 , the spring member 70 can be set toward the center in the left-right direction, and the front sides of the shoulder straps 62 and the like can be pulled outward to the left and right.
又，兒童座椅1構成為彈簧構件70可相對於靠背移位部14之彈簧構件安裝孔43裝卸。因此，兒童座椅1例如於體格較大之嬰幼兒就座，使用車輛側之安全帶之情形，即，不使用安全帶群4之情形時，可卸下彈簧構件70。藉此，兒童座椅1中，可避免不使用安全帶群4時之彈簧構件70與嬰幼兒之肩膀部分干涉。 Furthermore, the child seat 1 is configured such that the spring member 70 is detachable from the spring member mounting hole 43 of the backrest displacement portion 14 . Therefore, in the child seat 1, for example, when a large infant is seated and the seat belt on the vehicle side is used, that is, when the seat belt group 4 is not used, the spring member 70 can be removed. Thereby, in the child seat 1, it is possible to prevent the spring member 70 from interfering with the shoulder portion of the infant when the seat belt group 4 is not used.
再者，彈簧構件70將橫穿彈簧軸線X70之突出部71之剖面之形狀設為橢圓狀(圖8)。因此，彈簧構件70不僅容易朝使前端上下移位之方向撓曲，亦可大致同樣容易地朝使之左右移位之方向撓曲，幾乎不會有因方向引起之易撓曲度差異。藉此，兒童座椅1中，為將安全帶群4之鎖舌65***至搭扣64而將肩帶62等拉向左右內側時，可容易使彈簧構件70變形，而使肩帶62等密接於嬰幼兒之肩膀部分。 Furthermore, the spring member 70 has an elliptical cross-sectional shape of the protrusion 71 crossing the spring axis X70 (Fig. 8). Therefore, the spring member 70 can easily deflect not only in the direction of displacing the front end up and down, but also in the direction of displacing the front end left and right, and there is almost no difference in the degree of deflection depending on the direction. Thereby, in the child seat 1 , when the shoulder belts 62 etc. are pulled inward to the left and right in order to insert the locking tongue 65 of the seat belt group 4 into the buckle 64 , the spring member 70 can be easily deformed, and the shoulder belts 62 etc. can be easily deformed. Closely attached to the shoulders of infants and young children.
又，彈簧構件70設為不使突出部71相對於***部72於左右方向撓曲，而為左右對稱之形狀(圖6A、圖6B、圖7及圖8)。因此，兒童座椅1中，可將設置於左右各者之彈簧構件70設為互相同等之零件，即，謀求零件之共通化。藉此，兒童座椅1中，保護者將彈簧構件70分別安裝於靠背移位部14之左右之彈簧構件安裝孔43時，可不必在意該彈簧構件70之左右之分而容易安裝。 In addition, the spring member 70 is configured to have a left-right symmetrical shape without causing the protruding portion 71 to deflect in the left-right direction relative to the insertion portion 72 (Figs. 6A, 6B, 7, and 8). Therefore, in the child seat 1, the spring members 70 provided on each of the left and right sides can be made into mutually equivalent parts, that is, parts can be made common. Thereby, in the child seat 1, when the protector installs the spring members 70 in the left and right spring member mounting holes 43 of the backrest displacement part 14, the protector can easily install the spring members 70 without having to worry about the left and right sides.
