2121分别沿 左右方向朝连接部 1220的中部滑移。 如图 1和图 2所示， 当儿童安全座椅 100处于前向使用状态时， 系带本体 2100的两 端 （也即第一端部 2111和第二端部 2121） 分别位于两个定位槽 1222在左右方向上远离 连接部 1220的中部的一侧， 此时第一部段 21 10和第二部段 2120也分别位于儿童安全座 椅 100的左右两侧，系带本体 2100的两端分别从背靠部 1200向后延伸至与车辆的锚固点 连接的锚固部 2200 - 如图 3和图 4所示， 当儿童安全座椅 100处于后向使用状态时， 系带组件 2000仅在 儿童安全座椅 100左右方向上的一侧 （如图 3和图 4的左侧 L） 从背靠部 1200向后延伸 至车辆的锚固点， 具体的， 系带组件 2000整体位于儿童安全座椅 100在左右方向上的一 侧， 并自背靠部 1200的连接部 1220向后延伸至车辆的锚固点， 且系带本体 2100的两端 与背靠部 1200在左右方向上的同 ■侧连接， 具体的， 系带本体 2100的两端在左右方向上 共同位于同一定位槽 1222远离连接部 1220的中部的一侧， 也即第一部段 2110和第一部 段 2120位于儿童安全座椅 100在左右方向上的同一侧。 当此儿童安全座椅 100安装至车 辆座椅 200上时， 系带组件 2000整体在左右方向上远离车门设置， 而儿童安全座椅 100 在左右方向上未设置有系带组件 2000的一侧则临近车辆的车门设置， 以方便儿童看护者 从该侧将儿童抱进或抱出儿童安全座椅 100。 根据木公开，无论是前向使用状态还是后向使用状态，第一端部 2111和第二端部 2121 均位于定位槽 1222远离连接部 1220中部的一侧，此时笫一端部 21 1 1和第二端部 2121既 可以收容于定位槽 1222, 也可与定位槽 1222在左右方向上间隔设置。 当锚固部 2200与 车辆的锚固点连接时， 系带本体 2100被拉紧， 笫一端部 2111府笫二端部 2121沿左右方 向朝连接部 1220的中部移动时， 定位槽 1222的槽底均能阻挡第一端部 2111和第一 .端部 2121 , 以此将第一端部 2111和第二端部 2121限定于对应的定位槽 1222远离连接部 1220 中部的一侧， 避免在前向使用状态还是后向使用状态， 第一端部 2111和第二端部 2121沿 者连接部 1220朝靠近连接部 1220中部的 •侧滑移出对应的定位槽 1222 o 在本实施例中， 为了使儿童安装座椅 100由前向使用状态切换至后向使用状态， 需要 先断开锚固部 2200与车辆的锚固点之间的连接， 此时系带本体 2100呈松弛状态， 然后让 靠近车辆车门一侧的第一部段 21 10的第一端部 21 1 1或第二部段 2120的第二端部 2121从 对应的定位槽 1222远离连接部 1220的中部一侧， 滑移至连接部 1220的中部， 再滑移至 另一个定位槽 1222远离连接部 1220的中部一侧， 以使得第一端部 2111和第一 .端部 2121 位于同一定位槽 1222远离连接部 1220的中部一侧， 系带组件 2000整体位于儿童安装座 椅 100在左右方向上的同侧。 由于在后向使用状态卜， 连接部 1220距离车辆座椅 200的 锚固点更远， 此时可以通过调整件 2300, 延长第 ：部段 2110和第一部段 2120的整体延 伸长度。 如图 3和图 4所示， 与图 1、 2的前向使用状态相比， 第一部段 2110的第一端部 2111 由连接部 1220在左右方向一侧的定位槽 1222远离连接部 1220中部的一侧移动至连接部 1220在左右方向另一侧的定位槽 1222远离连接部 1220中部的一侧， 以与第二部段 2120 的第二端部 2121位于同一个定位槽 1222远离连接部 1220中部的一侧。 如图 2所示， 连接部 1220包括沿左右方向延伸的连接杆 122和位于连接杆 122下方 的定位件 1221 a,连接杆 122的左右两端与主体部 1210连接，其余部分向下与主体部 1210 间隔开， 定位件 1221 a布左布方向上的长度短于连接杆 122, 定位件 1221 a的中间部分向 上与连接杆 122连接，而定位件 1221a的左布两端则与连接杆 122在上下方向上间隔设置， 且定位件 1221a向卜与主体部 1210间隔开，两个定位槽 1222在上卜 '方向上设于连接杆 122 和定位件 1221a的左右两端之间。在本实施例中，定位件 1221a、连接杆 122和连接部 1220 在左右方向上的中心线 L重合。 在别的实施例中， 定位件 1221a也川 '以与连接部 1220一 体成型， 即 •件式构成。 图 5示出根据 ■实施例的儿童安全座椅 100向后安装的立体图。 与图 4不同地， 图 5 中去除了座椅本体 1000的后部盖板， 从而能够看到内部情况。 根据本实施例， 儿童安全座椅 100包括位于座椅本体 1000后侧的加强部 1240, 加强 部 1240例如为两根加强管， 连接部 1220被设置为 U型连接管， 连接在两根加强部 1240 上端。 加强部 1240沿背靠部 1200延伸至坐部 1100下方， 从整体上提供了加强作用， 以 防止儿童安全座椅 100变形。 有利地， 连接部 1220也可以与加强部 1240一体成型， 从而提供了更好的稳定性。 此 外， 加强部 1240也可以设置为一根或更多根， 或设置为其他形式， 本公开不以此为限。 图 5中还可以看到处于锚固部 2200, 锚固部 2200还包括弹性舌片， 弹性舌片将卡勾 封闭， 由此能够防止锚固部 2200从车辆座椅 200后侧的锚固点脱离。 图 6示出根据另一实施例的连接部 1220的示意图。 根据本实施例， 将图 1至 5中的 单个定位件 1221a替换成分别设置在连接杆 122的左右两侧的两个定位件 1221bo 两个定 位件 1221b自连接杆 122朝主体部 1210向下凸伸形成， 定位件 1221b包括向上与连接杆 122 连接的杆部 1221b-l 和与连接杆 122 在上下方向上间隔设置的头部 1221b-2, 杆部 1221b-l与头部 1221b-2相互连接，头部 1221b-2在左右方向上的尺寸大于杆部 1221b-l在 左右方向上的尺寸， 定位槽 1222在上下方向上形成在连接杆 122与头部 1221b-2远离连 接杆 122的中部一侧之同。 具体的， 定位件 1221b的形式例如为螺钉， 故其杆部 1221b-l 呈类圆柱形， 其头部 122lb-2为扁平圆形， 其中头部 1221b-2的直径大于杆部 1221b- 1的 直径， 杆部 1221b-l的中心线与头部 1221b-2的中心线重合。 杆部 1221b-l向上拧入连接 杆 122中并固定,使得扁平头部 1221b-2向上与连接杆 122间隔设置，以在扁平头部 1221b-2 与连接杆 122之间形成定位槽 1222,定位槽 1222具体位于连接杆 122与扁平头部 1221b-2 远离连接杆 122的中部 ■侧之间。 在别的实施例中， 两个定位件 1221b也可与连接杆 122 一体成型。 如图 6所示， 背靠部 1200还设有设于主体部 1210外侧的束缚带 1223, 束缚带 1223 在左右方向的两端与主体部 1210连接， 且束缚带 1223位于连接部 1220在前后方向上背 离坐部 1100的一侧目 .低于连接部 1220的顶端， 在本实施例中， 束缚带 1223绷紧设置在 连接部 1220的外侧。 如图 6所示， 背靠部 1200还设*设于主体部 1210外侧的连接带 1224, 连接带 1224 位于连接部 1220在前后方向上靠近坐部 1 100的一侧且低于连接部 1220的顶端， 连接带 1224的一端与主体部 1210连接， 连接带 1224的另一端设有收容袋 1226, 收容袋 1226用 于布不使用系带组件 2000时收容系带组件 2000 - 如图 7所示,连接带 1224与束缚带 1223相互连接，以在前后方向上围设连接部 1220, 具体的，连接带 1224可以延伸至连接部 1220的顶部再延伸至束缚带 1223靠近连接部 1220 的一侧， 使得连接带 1224与束缚带 1223在前后方向上部分重叠且相互连接， 并使得收容 袋 1226位于束缚带 1223的下方， 并显露出收容袋 1226的开口以收容系带组件 2000, 且 能有效避免收容袋 1226发生移动。 虽然连接带 1224与束缚带 1223在前后方向上围设连 接部 1220, 但并未遮盖连接部 1220与系带本体 2100连接的部分， 且连接带 1224围绕连 接部 1220设置的部分大致位于两个定位件 1221b之间， 在前向使用状态下或后向使用状 态下， 进一步阻挡了系带本体 2100的两端朝连接部 1220的中部移动， 当需要从前向使用 状态切换成后向使用状态时， 或从后向使用状态切换成前向使用状态时， 则需要将连接带 1224与束缚带 1223分离开，以允许系带本体 2100的两端中的一端沿着连接部 1220滑移。 在木实施例中， 连接带 1224与束缚带 1223通过扣具 1225连接， 扣具 1225包括可相 互扣合的公扣和母扣， 公扣和母扣中的一者设置在连接带 1224 与束缚带 1223中的一者， 公扣和母扣中的另一者设置在连接带 1224与束缚带 1223中的另一者。 在别的实施例中， 扣具 1225也可替换为由勾面和毛面组成的魔术贴或者拉链等， 在此不做限制。 在本实施例中， 连接带 1224与束缚带 1223连接之后， 收容袋 1226靠近连接部 1220 左右方向的一端设置， 以便于在系带本体 2100的两端移动至连接部 1220左右方向的同一 侧时收容至收容袋 1226中。 图 10至图 15示出根据另 •实施例的儿童安全座椅 100。 为简便说明， 仅描述与图 1 至 5的实施例的不同之处。 如图 10和图 11所示， 系带组件 2000的第一部段 2110的第一端部 2111和第一部段 2120的第二端部 2121 （图 10未示出） 分别连接在儿童安全座椅 100的座椅本体 1000的 坐部 1 100的左右两侧上， 具体连接至坐部 1 100的左右两侧的两个侧翼 1230 ±o 第一端 部 2111和第一 .端部 2121被固定至坐部 1100的两个侧翼 1230上对应的两个固定部 1250 中， 第一端部 2111和第二端部 2121可以穿过固定部 1250被固定至儿童安全座椅 100内 部， 固定部 1250例如是穿孔， 第一端部 2111和第一 .端部 2121 n；以设置日字扣、 蝴蝶结 等限位件， 限位件的尺寸大丁穿孔的尺寸， 避免第 ■端部 2111和第一端部 2121从固定部 1250中脱出。 如图 14所示， 背靠部 1200包括处于主体部 1210在前后方向远离坐部 110一侧的第 一连接件 1227、分别处于主体部 1210左右两侧的第二连接件 1228和第三连接件 1229（具 体位于卞体部 1210左右两侧的两个侧翼 1230的外侧） 。 其中， 第二连接件 1228与第一 端部 2111位于儿童安全座椅 100在左右方向上的同一侧， 第三连接件 1229与第二端部 2121位于儿童安全座椅 1。。在左右方向上的同一侧，第一连接件 1227、第二连接件 1228、 第二连接件 1229二者的结构一致， 仅设置位置不同。 如图 14所示， 第一连接件 1227、 第二连接件 1228、 第 〔连接件 1229的一端固定连 接至主体部 1210, 笫一连接件 1227、 第二连接件 1228、 笫 1连接件 1229的另一端与主 体部 1210可分离连接， 第一连接件 1227、 第一.连接件 1228、 第三连接件 1229的其余部 分与主体部 1210间隔设置， 且第一连接件 1227、 第二连接件 1228、 第三连接件 1229与 主体部 1210围设形成中空部 1260b, 系带本体 2100可以从第一连接件 1227、第一.连接件 1228、第三连接件 1229与土体部 1210可分离连接的 ■端进入到由对应的第 •连接件 1227、 第一连接件 1228、 第三连接件 1229与主体部 1210围设形成的中空部 1260b中， 使得系 带本体 2100可与背靠部 1200连接。第一连接件 1227、第一连接件 1228、第三连接件 1229 的形状适配系带本体 2100的宽度并能防止系带本体 2100脱离。 如图 14所示， 第一连接件 1227、 第二连接件 1228、 第三连接件 1229与主体部 1210 可分离连接的另一端 （具体为上端） 朝第一连接件 1227、 第二连接件 1228、 第三连接件 1229与主体部 1210固定连接的一端 （具体为下端） 弯折， 并呈弯钩状设置。 第一连接件 1227、 第二连接件 1228、 第三连接件 1229 甫具有弹性的材料制成， 在不受力的情况下， 第一连接件 1227、 笫二连接件 1228、 第-:连接件 1229的另一端紧贴主体部 1210, 当在 受到外力作用下， 第一连接件 1227、 第二连接件 1228、 第三连接件 1229的另一端则会与 主体部 1210分离，形成供系带本体 2100进入对应中空部 1260b的通道， 当系带本体 2100 进入对应的中空部 1260b后， 第一连接件 1227、 第二连接件 1228、 第三连接件 1229的另 一端又会继续紧贴主体部 1210, 进而防止系带本体 2100脱离中空部 1260b, 进而脱离与 背靠部 1200的连接。 在别的实施例中， 第一连接件 1227、 第二连接件 1228、 第三连接件 1229 的另 ■端也可与主体部 1210 间隔设置， 以形成供系带本体 2100进入对应中空部 1260b的通道， 无论儿童安全座椅 100在前向使用状态或后向使用状态下， 系带本体 2100 的延伸方向与系带本体 2100进入该通道的方向交错即可，例如将图 14所示的第一连接件 1227、 第二连接件 1228、 笫 1连接件 1229的上端与主体部 1210 |n］隔设置， 而非在未受 力时即紧贴主体部 1210的表面。 如图 10和图 11所示， 在儿童安金座椅 100朝向车辆的前方安装时， 第一部段 2110 和第一 .部段 2120分别处于儿童安全座椅 100左右两侧，通过第一部段 2110进入到由第二 连接件 1228与主体部 1210围设形成的中空部 1260b、 第二部段 2120进入到由第三连接 件 1229与主体部 1210围设形成的中空部 1260b中，以限制第 ：部段 2110和第一部段 2120 从对应的中空部 1260b中脱出， 以此将第一部段 2110和第一部段 2120从坐部 1100延伸 至背靠部 1200, 再从背靠部 1200延伸至车辆的锚固点。 通过第一连接件 1228和第三连 接件 1229, 在系带组件 2000的锚固部 2200与车辆座椅 200的靠背 220后侧的锚固点连 接后， 第一部段 2110和第二部段 2120能够提供足够的力， 将儿童 .安全座椅 100的背靠部 1200固定贴靠至靠背 220, 以防止脱离靠背 220。 在本实施例中， 与第一部段 2110、 第二 部段 212。连接的两个固定部 1250相对儿童安全座椅 1。。的中心线 1（与背靠部 12。。的中 心线 I重合） 对称设置， 与第一部段 21 10、 第二部段 2120连接的笫二连接件 1228、 第三 连接件 1229也相对儿童安全座椅 100的中心线 T（与背靠部 1200的中心线 T重合） 对称 设置， 第一连接件 1227被设置在背靠部 1200的中心线 T上。 根据图 10、 11 , 第一部段 2110在儿童安全座椅 100在左右方向的一侧自坐部 1100 向后延伸至第二连接件 1228和主体部 1210之间，再从第二连接件 1228和主体部 1210之 间向后延伸至车辆的锚固点， 第二部段 2120在儿童安全座椅 100在左右方向的另一侧自 坐部 1100向后延仲至第三连接件 1229和主体部 1210之间，再从第三连接件 1229和土体 部 1210之间向后延仲至车辆的锚固点。 根据图 12、 13, 当儿童安全座椅 100处于后向使用状态时， 系带组件 2000的第一部 段 2110位于儿童安全座椅 100在左右方向上的一侧（如图 12中的左侧 L）,并从坐部 1100 向前延伸至背靠部 1200, 再从背靠部 1200向后延伸至与车辆座椅 200的锚固点连接的锚 固部 2200, 系带绢件 2000的第二部段 2120位于儿童 .安全座椅 100在左右方向上的另一 侧（如图 12中的右侧 R）,并自坐部 1100向后延伸至与车辆的锚固点连接的锚固部 2200 o 可见， 系带组件 200仅在儿童安全座椅 100左右方向上的一侧从背靠部 1200向后延伸至 车辆的锚固点。 如图 12和图 13所示， 具体的， 在后向使用状态下， 此时第一连接件 1227位于主体 部 1210的前侧，第一部段 2110的第一端部 2111自对应的固定部 1250向前先延伸至笫二 连接件 1228与主体部 1210之间（也即第一部段 2110穿过第一.连接件 1228与主体部 1210 围设形成的中空部 1260b） , 再向前延伸至第一连接件 1227 的前侧， 然后再向后延伸至 第一连接件 1227和主体部 1210之间（也即第一部段 2110穿过第一连接件 1227与主体部 1210围设形成的中空部 1260b） , 再向后延伸至第一连接件 1228与主体部 1210之间， 最 后延伸至锚固部 2200, 锚固部 2200再连接至车辆的锚固点。 通过此种方式， 提供了儿童 安全座椅 100的背靠部 1200的固定， 以防止背靠部 1200向前倾倒。 而第一部段 2120自 对应的固定部 1250直接向后延伸至锚固部 2200 o 当此状态下的儿童安全座椅 100安装至 车辆座椅 200上时， 第一部段 2100远离车门设置， 而第二部段 2120靠近车门设置， 且并 未阻挡儿童看护者将儿童抱进或抱出。别的实施例中， 在后向使用状态卜 '， 第一部段 2110 的第一端部 2111 可 '自对应的固定部 1250直接向前延伸至第一连接件 1227的前侧， 再向 后延伸至第一连接件 1227和主体部 1210之间， 最后延伸至锚固部 2200, 锚固部 2200再 连接至车辆的锚固点。 或者第 ■部段 2110的第 ■端部 2111 自对应的固定部 1250直接向 前第一连接件 1227的前侧， 再向后延伸至第一连接件 1227和主体部 1210之间， 再向后 延伸至第一连接件 1228与主体部 1210之间， 最后延伸至锚固部 2200, 锚固部 2200再连 接至车辆的锚固点。 如图 12所示， 当儿童 .安全座椅 100处于后向使用状态时， 与图 10的前向使用状态相 比， 第二部段 2120从第二连接件 1228中脱离。 如图 15所示， 从第一连接件 1227处剖开 （从背靠部 12。。的中心线处剖开） 。 可以 看到， 第一连接件 1227在上端具布 ■回型弯， 以防止系带组件 2000脱离， 笫一连接件 1227 的下端倾斜地伸入背靠部 1200中， 并固定至与主体部 1210固定连接的一加强部 1240。 根据本实施例， 加强部 1240垂直于图面方向延伸， 有利地保证了笫一连接件 1227的连接 强度。 本公开中的儿童安金座椅，在后向使用状态卜，系带组件 2000仅在儿童安金座椅 100 左右方向上的一侧从背靠部 1200向后延伸至车辆的锚固点， 而儿童安全座椅 100左右方 向上的另 侦并未设有从背靠部 1200向后延伸至车辆的锚固点的系带组件 2000, 使得儿 童看护者在该侧抱进或抱出儿童的通道不受阻挡， 通常该侧靠近车门设置， 因此儿童进出 儿童安全座椅 100及车辆时， 不需拆卸系带组件 2000, 便于儿童看护者从该侧直接将儿 童抱进或抱出儿童安全座椅 100及车辆， 使得使用更方便。 图 16至图 21示出根据又一实施例的儿童安全座椅 100o为简便说明， 仅描述与图 10 至 15的实施例的不同之处。 如图 16所示,背靠部 120。的上部设*上固定部 127。,坐部 11。。设 ”下固定部 1280, 它们用于与系带木体 2100的端部连接。 上固定部 1270可以设置于背靠部 1200的上部的中间或侧部。在一种实施例中， 上固 定部 1270设置于背靠部 1200的上部的远离车门的一侧。 在上固定部 1270设置为两个的实施例中，两个上固定部 1270可以分别对称地位于背 靠部 1200的左右两侧的两个侧翼 1230, 如图 16和图 17所示， 分别可以看到背靠部 1200 的右侧的上固定部 1270和背靠部 1200的左侧的上固定部 1270- 下固定部 1280可以设置于座部 1100的侧部。 在一种实施例中， 下固定部 1280设置 丁 •座部 1100的临近车门的 ■侧 o 在下固定部 1280设置为两个的实液例中，两个下固定部 1280可以分别对称地位于坐 部 1100的左右两侧的两个侧翼 1230, 如图 16和图 17所示， 分别可以看到坐部 1100的 右侧的下固定部 1280和坐部 1 100的左侧的下固定部 1280- 上固定部 1270和下固定部 1280的结构可以与前述固定部 1250的结构相同或不同， 例如是穿孔、 固定环或固定钩等。 在图 17所示的上固定部 1270或卜'固定部 1280是穿孔的实施例中，系带组件 2000的 系带本体 2100的两个端部 （即， 图 17所示的第一端部 2111和第二端部 2121） 可以穿过 该穿孔被固定至儿童安全座椅 100的面向乘坐空间的 ■侧。系带本体 2100的两个端部 2111、 2121可以设置日字扣、蝴蝶结等限位件 2700。在限位件 2700的尺寸大于穿孔的尺寸的情 况下， 可以避免第一端部 2111和第一端部 2121从穿孔中脱离。 在一种实施例中， 限位件 2700被设置成， 其一个方向的尺寸大于穿孔的尺寸， 另一方向的尺寸小于穿孔的尺寸， 这使得限位件 2700可以沿所述另一方向从穿孔中脱离， 从而系带本体 2100的两个端部 2111、 2121与上固定部 1270、 下固定部 1280可拆卸地连接， 有助于儿童看护者调整系带 本体 21。。的端部与不同的上固定部 1270或下固定部 128。连接。 为了增加上固定部 1270和下固定部 1280中的至少一者的强度， 如图 17所示， 上固 定部 1270和 /或下固定部 1280设有加强件 1500, 其被固定至儿童安全座椅 100。 例如， 加强件 1500可以采取塑料或金属等较硬的材质， 呈片状或块状等合适的形状， 并可以通 过螺接或焊接等方式固定至儿童安全座椅 100的内部。 应该明白， 根据本公开的儿童安全座椅 100 可'以不设有下固定部 1280, 如后文将描 述的图 20所示的情况。 另外， 上固定部 1270和下固定部 1280可以设置在儿童安全座椅 100的不同侧， 也可 以设置在儿童安全座椅 100的同 ■侧。 在上固定部 1270或下固定部 1280采用固定环或固定钩的其他实施例中， 同样可以实 现系带本体 2100的两个端部 211 K2121与上固定部 1270、下固定部 1280可拆卸地连接。 图 17和图 18示出根据本实施例的儿童安全座椅 100处于前向使用状态的立体图。其 中， 背靠部 1200的上部设有两个上固定部 1270o 这两个上固定部 1270可以对称设置， 也可以不对称设置。 系带本体 21。的第一端部 2111 （参见图 18） 和第二端部 2121 （参见 图 17） 分别连接于两个上固定部 1270。 系带组件 2000可以包括位于第一端部 2111与第 二端部 2121 之间的用于与车辆的锚固点连接的锚固部 2200 以及用于调节长度的调整件 2300。 锚固部 2200和调整件 2300的结构可以与前述实施例相同。 如图 17和图 18所示， 系带组件 2000从背靠部 1200的上部处的两个上固定部 1270 向后延伸， 通过锚固部 2200连接至车辆的锚固点， 从而使儿童安仝座椅 100以前向使用 状态固定至车辆座椅。 图 19A和图 19B示山根据乂一实施例的儿童安全座椅处于后向使用状态的一种方案 的立体图。 在图 19A和图 19B所示的实施例中， 系带本体 2100的两个端部分别连接至位于儿童 安全座椅 100的左右方向上的不同侧的上固定部 1270和下固定部 1280o 具体而言， 系带 本体 2100的第一端部 21 1 1连接至位于儿童安全座椅 100的左右方向上的一侧的下固定部 1280, 这使得系带本体 2100的位于该侧的一部分不会妨碍儿童看护者从该侧将儿童抱进 或抱出儿童安金座椅 100= 系带本体 2100的第一 .端部 2121连接至位于儿童安全座椅 100 的左右方向上的另一侧的上固定部 1270, 这使得系带本体 2100的位于该另一侧的另一部 分能够将背靠部 1200的上部连接至车辆的锚固点， 由此实现系带组件 2000在儿童安全座 椅 100的左右方向上的仅 ：侧连接背靠部 1200的上部与车辆的锚固点， 以避免儿童安全 座椅 100在车辆刹车或发生碰撞时向前翻覆。 在该实施例中， 当系带本体 2100的端部所连接的下固定部 1280位于儿童安全座椅 100的临近车门的一侧、 系带本体 2100的端部所连接的上固定部 1270位于儿童安全座椅 100的远离车门的另一侧时， 将能够大大方便儿童看护者从车门的一侧将儿童抱进或抱出 儿童安全座椅 100。 囚此， 在系带本体 2100的两个端部 2111、 2121与上固定部 1270、 下 固定部 128。可拆卸地连接的情况下，儿童看护者可以根据实际情况调整系带本体 21。。的 端部与不同的上固定部 1270或下固定部 1280连接。 图 20示出根据又一实施例的儿童安全座椅处于后向使用状态的另一种方案的立体图。 布图 20所示的实施例中， 系带本体 2100的一个端部 2121连接至位于儿童安全座椅 100的左右方向上的一侧的上固定部 1270, 另一个端部处设有锚固部 2200, 这使得系带 本体 2100在儿童安全座椅 100的左右方向上的该侧连接背靠部 1200的上部与车辆的锚固 点， 由此同样可以实现系带组件 2000在儿童安全座椅 100的左右方向上的仅一侧连接背 靠部 1200的上部与车辆的锚固点。 同时， 由丁 ■儿童安全座椅 100的左右方向上的另 ：侧 不存在系带本体 2100, 所以儿童看护者可以方便地从该另 ：侧将儿童抱进或抱出儿童安 全座椅 100o 在该实施例中， 可以不设置下固足部 1280。 作为上述实施例的变型方案，系帝本 # 2100可以将锚固部 2200设置于两个端部 2111、 2121之间， 当儿童安全座椅 1。。处于后向使用状态时， 这两个端部 2111、 2121均连接至 儿童安全座椅 100的同一个上固定部 1270。 图 21 示出根据又一实施例的儿童安全座椅处于后向使用状态的又一种方案的立体图。 在图 21所示的实施例中，儿童安全座椅 100的左右方向上的同一侧设有上固定部 1270 和下固定部 1280以及连接两者的滑动机构 1400o 该滑动机构 1400被设置成使得系带本 体 2100的端部 （例如， 第一端部 2111） 能够借助于滑动机构 1400从上固定部 1270和卜 固定部 1280中的一者滑动至另一者并定位。 这样， 当儿童安仝座椅 100进行前向使用和 后向使用的转换口寸， 系带本体 2100的端部 （例如， 第一端部 2111） 不需拆卸， 直接滑动 至相应的上固定部 1270或下固定部 1280并定位即可， 使用更方便。 滑动机构 1400可以设置于儿童安全座椅 100的左右方向上的一侧或两侧的外表面上 （例如，侧翼 1230的外表面上）的滑槽或滑轨。与之对应地，系带本体 2100的端部 2111、 2121可以设有能够在滑槽或滑轨上滑动的滑动件。 布发明人已知的一种具有顶部系绳的儿童安全座椅，为保证顶部系绳与儿童安全座椅 之间的连接强度，儿童安全座椅的背靠部的壳体内部设有沿背靠部的长度方向（纵向方向） 延伸的加强管， 顶部系绳固定连接在加强管结构上。但是为该加强会造成产品成本和重量 增加， 结构复杂等问题。 图 1至图 7示出本公开第 ■实施例， 其中， 图 1示出儿童安全座椅 H1的前侧立体图 并示出局部 A的细节， 图 2示出儿童安全座椅 H1的后侧立体图， 图 3示出儿童安全座椅 H1的后侧正视图， 图 4A和图 4B示出根据图 1的儿童安全座椅 H1沿剖线 I-I的剖面图； 图 5示出局部 A在图 4中的细节， 图 6和图 7示出加强部 H150的立体图。 参见图 1 , 儿童安全座椅 H1包括供儿童乘坐的座椅本体 H100、 将座椅本体 H100连 接至车辆的系带组件 H200、 以及处于座椅本体 H100下方的底座 H300o 底座 H300被放 置在车辆座椅 （未示出） 上， 底座 H300承载座椅本体 H1。。并可相对车辆座椅固定。 座 椅本体 H100包括与儿童下半身接触的坐部 H1 10、 与儿童上半身接触的背靠部 H120、 以 及与儿童头部接触的头靠部 H140。背靠部 H120包括用于支撑儿童背部的背靠部主体 H121 和保护儿童两侧的侧翼 H130o 背靠部 H120具有由如聚丙烯 （Polypropylene, PP） 或 ABS （Acrylonitrile Butadiene Styrene） 等高强度的工程塑料制成的壳体， 壳体两侧具有长条形 穿孔 H123 o 背靠部主体 H121和侧翼 H130町直接由壳体形成或由壳体包覆。 系带组件 H200设置于座椅本体 H100的上部，用于将座椅本体 H100连接至车辆的锚 固点 （未示出） ， 锚固点 ■般设置在车辆座椅的后侧， 系带组件 H200将座椅本体 H100 连接至车辆的锚固点， 从而避免座椅本体 H100在车辆刹车或发生碰撞时向前翻覆， 给乘 坐于座椅本体 H100的儿童带来危险。 系带组件 H200包括系带本体 H210和锚固部 H220, 锚固部 H220用于与车辆的锚固 点连接。 根据本实施例， 锚固部 H220例如为卡勾， 卡勾用于勾扣车辆的锚固点。 卡勾滑 动连接于系带本体 H210, 系带本体 H210为长条形带材， 具有扁平的横截面。 系带本体 H210可以由一根织物形成， 或中多根织物组合而成。可选地， 系带组件 H200还具 4设置 在系带木体 H210 上的调整件 H230, 调整件 H230用于调整系带木体 H210的长度， 其具 有能够视觉感知系带本体 H210的松紧状态的指示器 H231（如红绿指示器），指示器 H231 位于调整件 H230的一侧而。 当儿童安仝座椅 H1 处于前向使用位置时， 系带本体 H210 向儿童安全座椅 H1的后方延伸， 此时调整件 H230具有指示器 H231的一侧面朝向上方， 以便于看护者观察。 当调整件 H230具有指示器 H231的一侧面朝向卜'方时， 则不利于看 护者观察。在使用中，希望将该展示侧面始终面朝看护者， 以便看护者观察系带本体 H210 的松紧状态。因此，看护者需要翻转系带本体 H210的端部， 以调整调整件 H230的朝向， 宙此会导致系带本体 H210上产生卷绕。 调整件 H230也可以以另外的形式设置， 本公开 不以此为限。 根据本公开， 系带本体 H210包括第一部段 H211和第一部段 H212。 第一部 段 H211和第一部段 H212的远离座椅本体 H100的一端为第一端部 H213。第一部段 H211 和第二部段 H212的自由端形成系带本体 H210的第二端部 H214, 第二端部 H214可松开 地连接座椅本体 H100o 根据本公开， 第 - .端部 H214从座椅本体 H100面朝车辆的外侧穿过座椅本体 H100 并通过系带组件 H200的连接件 H240连接至座椅本体 H100内侧。 例如， 第一 .端部 H214 可以通过图 2和图 3 中所示的处于背靠部 H120两侧的 K条形穿孔 H121 穿过座椅本体 H100, 由此将系带本体 H210由座椅侧面导入， 使得第 ■部段 H211的第一端部 H214和 第一部段 H212的第一端部 H214 （被遮挡而未示出） 之间的横向跨度更宽， 背靠部 H120 能更稳定地贴合于车辆背靠。此外，穿孔 H121基本上沿座椅本体 H100的高度方向延伸， 系带本体 H210的织带能够垂直于车辆座椅朝向车辆座椅延伸， 使得织带在使用中不会被 折叠。也就是说，系带本体 H210能够始终以展开状态连接在车辆座椅与儿童安全座椅 H1 之间， 从而获得更好的拉紧。 根据本公开， 儿童安全座椅 H1具*前向使用模式（见图 4A）和后向使用模式（见图 4B） 。 当儿童安全座椅 H1 安装至车辆座椅且处于前向使用模式时， 儿童坐入座椅本体 H100后， 面朝车辆的前方， 儿童安全座椅 H1 的开口方向朝向车辆的车头方向， 背靠部 H120抵顶车辆座椅的靠背， 此时系带组件 H200位于儿童安全座椅 H1的开口方向的后方 （以卜 '称为前向安装位置） ， 以便锚固部 H220卡合位于车辆座椅后方的锚固点。 当儿童 安仝座椅 H1安装至车辆座椅且处于后向使用模式时， 儿童坐入座椅本体 H100后， 面朝 车辆的后方（图未示山），儿童安全座椅 H1的开口方向朝向车辆的车位方向，背靠部 H120 远离车辆座椅的靠背， 此时系带组件 H200位于儿童安全座椅 H1的开口方向的后方 （以 下称为后向安装位置） ， 以便锚固部 H220卡公位于车辆座椅后方的锚固点。 宙丁系带本 体 H210的横截面是扁平状的，当系带组件 H200从后向安装位置移动到前向安装位置时， 系带本体 H210将产生内外翻转， 即系带本体 H210内侧面翻转至外侧面。 在发明人已知 的儿童安全座椅中， 顶部系绳的一端固足连接加强管， 当锚固部 H220卡合锚固点时， 锚 固部 H220与连接件之间的系带本体 H210会形成折叠，由此会造成系带本体 H210的磨损。 参见图 1的局部放大图，连接件 H240与加强部 H15。为分体件，连接件 H240可以相对于 加强部 H150自由活动。 当系带组件 H200从后向安装位置移动到前向安装位置时， 系带 本体 H210的笫二端部 H214能够带动连接件 H240转动， 以避免在系带本体 H210将因转 而形成折叠段。 图 1至图 4A示出了儿童安全座椅 H1为前向使用模式。 在此状态下， 系带本体 H210 位于前向安装位置， 即系带组件 H200的系带本体 H210远离儿童安全座椅 H1的前侧，并 向后延伸至车辆座椅的锚固点。 在图 4B示出的后向使用模式中， 系带本体 H210位于后 向安装位置， 即系带本体 H210朝相反于图 1 ± 3的方向延伸， 并从儿童安全座椅 H1的 前侧延仲至车辆座椅的锚固点。 根据本实施例， 儿童安全座椅 H1还包括加强部 H150o 加强部 H150设置于座椅本体 H100与连接件 H240之间， 用于加强系带本体 H210与座椅本体 H100连接位置的强度。 同时参看图 1、 图 4A、 图 5和、 图 6和图 7来描述加强部 H150o 图 5示出局部 A在 图 4A中的细节， 座椅本体 H100的背靠部 H120具有供儿童背靠的主体 H121 和与主体 H121一体成型的结合部 H122, 结合部 H122用于与侧翼 H126结合。加强部 H150设置于 结合部 H122, 穿孔 H121设置于结合部 H122, 用于系带本体 H210的第一部段 H211的穿 设。 此外， 座椅本体 H100还包括横杆 H160, 横杆 H160设置于背靠部 H120并沿座椅本 体 H100的宽度方向延伸。横杆 H160可以加强背靠部 H120的强度并可作为肩带管 H160, 用于儿童安全座椅 H1的肩带 H162的支撑和换向。横杆 H160通过螺钉 H161固定至背靠 部 H120。 加强部 H150具有抵接部 H153和固定部 H154o 抵接部 H153布直于背靠部 H120的 卞休 H121 目.被设置为平面，用于与系带本体 H210的连接件 H240进行抵接。固定部 H154 设置为两个，图 5中右上方的固定部 H154和左下方的固定部 H154从抵接部 H153的两侧 朝相反方向垂直伸出，两个固定部 H154相互平行并分别具*连接孔 H157。为了将加强部 H150固定至背靠部 H120, 可以将螺钉穿过连接孔 H157拧入背靠部 H120中设置的固定 孔 H124。 在加强部 H150固定至背靠部 H120之后， 将侧翼 H126结合至背靠部 H120的 结合部 H122, 从而能够遮挡图 1和图 5中左下方的固定部 H154, 以避免螺钉无意中松动 脱离并造成加强部 H150从背靠部 H120脱离。 加强部 H150还具有从抵接部 H153凸起的引导部 H152,引导部 H152从抵接部 H153 的表面延伸至座背靠部 H120的壳体处的穿孔 H123 （见图 5） 。 引导部 H152的内部形成 引导孔 H151 , 引导孔 H151 ■侧的开口与穿孔 H121对齐， 另 ■侧开口位丁抵接部 H153 的远离穿孔 H121的表面， 系带本体 H210穿设在引导孔 H151内， 并从穿孔 H121穿出背 靠部 H120的壳体。由此可以更好引导系带本体 H210相对于座椅本体 H100的滑动， 防止 系带本体 H210折叠或卡住。 在其他实施例中， 引导部 H152也可以不延伸至穿孔 H121 , 本公开不以此为限。 引导孔 H151在抵接部 H153表面处的开门横截面设置为长条形（参见图 6）并沿座椅 本体 H100的长度方向延伸 （参见图 1） o 引导孔 H151在中部具有扩宽部 H158o 例如， 引导孔 H151在抵接部 H153表面处的开口的宽度从两端至中部逐渐变大。 引导孔 H151 的中部的扩宽部 H158宽度大于其两个端部的宽度。 由此， 当系带组件 H200位于前向安 装位置或者后向安装位置并被拉紧时， 引导孔 H151 的端部较窄， 能防止系带本体 H210 滑动。 当系带组件 H200在前向安装位置府后向安装位置之间切换时， 系带本体 H210能 够在较宽的扩宽部 H158处翻转方向， 以避免卷绕和折叠。 在本实施例中， 2个穿孔 H123分别设置在背靠部 H120的壳体的左右两侧， 由此， 当 系带本体 H210 位于后向安装位置小 j, 系带本体 H210 不会从背面到侧面卷绕在背靠部 H120的壳体上， 因此可以降低两者之间的摩擦面积。另外， 当系带本体 H210从前向安装 位置向后向安装位置之间切换时， 系带本体 H210不会接触背靠部 H120的后面和侧面的 拐角处， 也能够避免系带本体 H210出现卷绕和折叠。 在其他实施例中， 穿孔 H123也可 以设置在背靠部 Hl 20的背面。 系带组件 H200的连接件 H240设置为扁平扣 H240o 如图 1所示， 连接件 H240设置 为长条形片材， 其在系带本体 H210拉紧的状态卜 '基本上沿座椅本体 H100的高度方向延 伸。 连接件 H240具有至少两个平行开口 H241 , 系带本体 H210的第一 .端部 H214的自由 端顺序穿过至少两个平行开口 H241 , 并在 H180度转变方向后与第一 .端部 H214的其余部 分叠置且可以设置为固定连接， 例如缝合、 粘合等 （参见图 5） 。 连接件 H240也可以具 有三个或更多个平行开口 H241 o 连接件 H240的扁平侧面平行抵接加强部 H150的表面， 扁平侧面的面积大于引导孔 H153在抵接部 H153处的开口面积， 从而在系带本体 H210 的第一端部 H213被固定至车辆座椅的情况下， 连接件 H240能够从座椅内侧卡靠在抵接 部 H153上， 以提供系带本体 H210的第二端部 H214的卡接。 由于引导孔 H153的开口为 长条形目.连接件 H240被设置为扁平长条形片材， 在安装时可以将连接件 H240先从座椅 外侧水平插入引导孔 H153, 在穿过引导孔 H153伸出至座椅内侧以后， 将连接件 H24。变 换方向， 从而卡接在抵接部 H153 ± （参见图 5） 。 布儿童安全座椅 H1从图 1至 3中的前向使用模式转变为后向使用模式或从后向使用 模式转变为前向使用模式时， 系带本体 H210例如会从图 1的向后延伸变换为向前延伸。 在此情况卜，例如系带本体 H210的调整件 H230的用于展示系带本体 H210松紧状态的展 示侧面会发生翻转， 使得看护者无法容易观察系带本体 H210的松紧状态。 如看护者希望 直接看到展示侧面，则需要将系带本体 H210在引导孔 H151中翻转 H180度， 同口寸需要将 连接件 H240从图 1所示状态翻转 H180度。在翻转过程中，系带本体 H210的织带由于其 宽度在引导孔 H153中会发生变形和挤压， 供至被引导孔 H153卡住。 根据本公开，在引导孔 H153中设置逐渐变宽的扩宽部 H158,从而在翻转连接件 H240 和系带本体 H210时防止织带被引导孔 H153卡住。 参见图 5, 加强部 H150还具有垂直于抵接部 H153的凸出部 H156, 用于抵接背靠部 H120的主体 H121 o 同时， 凸出部 H156加强了固定部 H154的强度。 根据本公开， 凸出 部 H156与横杆 H160形状适配， 具体形式可以相应进行变换， 本公开不以图示为限。 此外，加强部 H150在背离连接件 H240的一侧设置有多个肋部 H155,这些肋部 H155 可以卡接背靠部 H120的主体 H121或结合部 H122处设置的凸起 H155, 从而附加提供形 状接合， 以避免错位并加强部件强度 （参见图 5、 图 7） o 图 8至图 12示出本公开笫二实施例， 图 8示出根据第二实施例的儿童安全座椅 H1 的前侧立体图并示出局部 B的细节， 图 9示出根据第一 .实施例的儿童安金座椅 H1的前侧 立体图， 图 10示山根据第二实施例的系带组件 H200的立体图， 图 11示出根据图 9的儿 童安全座椅 H1沿剖线 II-II的剖面图；图 12示山局部 B在图 11中的细节图。为避免重复， 仅阐述与第 1实施例的不同之处。 根据第一实施例，在横杆 H160在靠近背靠部 H120的结合部 H122的两端位置设置有 加强部 H170o 加强部 H170被设置为扁平加强铁片， 具有与横杆 H160固定连接的固定部 H171和开口 H172。 加强部 H170的形状大致为矩形。 如图 9所示， 矩形的侧边也可以设 置有缺口， 以避开背靠部 H120上的部件或成型部。固定部 H171设置于加强部 H170的一 侧， 例如设置在矩形的一个拐角处。 开口 H172设置于加强部 H170的中部， 形式为长条 形。 固定部 H171可 '以设置为圆孔， 位于加强部 H170的一端， 横杆 H160插入圆孔后进行 焊接连接， 更进一步增加了连接强度。 根据本公开， 加强部 H170相对于座椅本体 H100 的高度方向以 淀的角度从横杆 H160伸出，开口 H172位于加强部 H170的另 ：端，并沿 座椅本体 H100的高度方向延伸， 从而使得系带本体 H210能够始终以展开状态连接在车 辆座椅与儿童安全座椅 H1之间。可选地， 加强部 H170的开口 H172的中部也具有扩宽部
（图未示出） ， 以使得开 H H172的中部的宽度大于两个端部的宽度。 图 13、 图 14和图 15示出本公开第三实施例， 其中， 图 13示出根据第三实施例的儿 童安全座椅 H1的前侧立体图并示出局部 C的细节， 图 14示出图 13的儿童安全座椅 H1 沿剖线山 -III的剖面图； 图 15示出局部 C在图 14中的细节图。 在第三实施例中， 在背靠部 H120的结合部 H122处设置第一加强部 H150, 与第一加 强部 H150平行地设置笫二加强部 H170, 第二加强部 H170固定至横杆 H160。 系带组件 H200的连接件 H240依次穿过座椅本体 H100中的穿孔 H123、第一加强部 H150的引导孔 H151和第一 .加强部 H170的开口 H172并抵接在第一 .加强部 H170上， 从而进一步加强了 系带组件 H200与座椅本体 H100的连接件位。 根据本公开，在儿童安全座椅 H1的座椅本体 H100上对应系带组件 H200的连接处固 定连接有加强部 H150和 /或加强部 H170o加强部 H150和 /或加强部 H170用于加强儿童安 全座椅 H1上系带组件 H200连接位置的强度。加强部 H150和 /或加强部 H170可以为塑胶 材质， 其成本低、 重量轻、 且易加工。 加强部 H150和 /或加强部 H170也可以由其他材料 制成。通过设置加强部 H150和 /或加强部 H170, 儿童安全座椅 H1的背靠部 H120可以以 较容易的形式被模制， 从而节省了材料并减少了制造难度。 由于本申请能够以多种形式具体实施而不脱离本申请的精神和实质， 所以应当理解， 上述实施例不限于任何前述的细节，而应在权利要求书所限定的范围内进行最广泛的解释, 囚此落入权利要求或其等效范围内的全部变化都应为权利要求所涵盖。
