本实用新型在其中一个实施例中公开了如图1所示，一种安全带调节结构，包括靠背1和设置在靠背上的安全带2，如图2所示，安全带2包括肩带21，肩带21的端部设有第一固定结构22。
靠背1上设有沿靠背1的长度方向设置的第一固定孔10以及沿靠背1的高度方向设置的第一调节孔11，第一固定孔10和第一调节孔11贯穿靠背1；
如图3所示，第一固定孔10为长孔，第一固定孔10靠近从靠背1的内侧向靠背1的外侧沿靠背1的高度方向向下倾斜设置；
多个第一固定孔10沿靠背1的高度方向间隔设置，第一调节孔11将多个第一固定孔10连通；
固定时，肩带21穿过其中一个第一固定孔10并通过第一固定结构22限制肩带21与靠背1分离；
调节时，肩带21能够沿第一调节孔11移动至其他第一固定孔10。
其中，如图8所示，安全带2为五点式安全带2，其包括两组肩带21、两组腰带23、裆带25以及卡扣结构26，因此，对应地，在靠背1的左右两侧分别各设置有一组第一固定孔10和第一调节孔11。卡扣结构26与裆带25连接，两组肩带21的端部以及两组腰带23的端部均能够与卡扣结构26可拆卸连接，在乘坐时，可将肩带21与腰带23与卡扣结构26分离以便于儿童进行穿着佩戴安全带2。
具体地，肩带21为柔性带，第一固定结构22的硬度大于肩带21的硬度，从而使得第一固定结构22能够方便插入或拔出第一固定孔10，且使得第一固定结构22能够稳定地抵在靠背1的背面实现限位。第一固定孔10与肩带21适配，肩带21能够从靠背1的正面穿过第一固定孔10至靠背1的背面并与设置在靠背1背面的第一固定结构22连接，并通过第一固定结构22限制肩带21与靠背1分离。如图1和3所示，多个相同的第一固定孔10分别沿靠背1的高度方向等距间隔设置，即多个第一固定孔10分别沿图示的上下方向设置，第一固定孔10和第一调节孔11的轴线沿靠背1的前后方向设置，第一调节孔11沿靠背1的高度方向设置，即第一调节孔11的沿图示的上下方向设置并且第一调节孔11将多个第一固定孔10连通，使得肩带21能够通过第一调节孔11移动至不同的第一固定孔10中，从而实现调整肩带21的高度。
进一步的，如图5所示，靠背1包括靠背骨架17，在靠背骨架17的中部设有沿靠背骨架17的高度方向设置的加强板171，通过加强板171能够加强靠背骨架17的结构强度。另外，在靠背骨架17上还设有多组加强筋以增强靠背骨架17的结构强度。其中，第一固定孔10和第一 调节孔11贯穿靠背骨架17。
其中，如图5所示，在第一调节孔11的外周设有工艺凹口172，通过工艺凹口172能够减少第一调节孔11周边的应力集中，提高靠背骨架17的结构强度。
再进一步的，如图1所示，靠背骨架17的两侧向靠背骨架17的正面弯曲以形成用于限制乘坐者左右活动的侧板18，如图4所示，在侧板18上设有多组沿靠背1的长度方向设置的横向加强筋173以用于增强侧板18的结构强度。在靠背骨架17上设有多组沿靠背1的高度方向设置的纵向加强筋174，以用于增强靠背骨架17的纵向结构长度。
其中，如图1所示，图示的左右方向为靠背的长度方向，图示的上下方向为靠背的高度方向，图示的前后方向为靠背的宽度方向。
具体地，第一固定孔10靠近靠背1的纵向中线的一端为高位端，第一固定孔10远离靠背1的纵向中线的一端为低位端，通过将第一固定孔10倾斜设置的形式能够使得肩带21能够与乘员的肩部适配，使得肩带21能够与乘员的肩部贴合度提高，提高使用舒适性。
在本申请中，使用者能够根据自身的身高对肩带21的高度进行调节，在调节肩带21的高度时，使用者只需将肩带21进行扭转使其进入至第一调节孔11中，并拉动肩带21沿第一调节孔11移动至不同高度的第一固定孔10中，然后再将肩带21扭转至固定在第一固定孔10中即可，此时肩带21在第一固定结构22的作用下不会与靠背分离，从而能够实现调整肩带21的高度以适应不同高度和年龄段的使用者进行使用。另外，本申请中当肩带21处于第一固定孔10中时，由于第一固定孔10为倾斜设置，因此肩带21也会倾斜，使得肩带21能够适应人体肩膀的形状并与肩膀进行贴合，从而能够避免肩带21在使用时从肩膀脱落，约束性更好。
进一步的，在肩带21上套设有缓冲套，缓冲套能够增大人体与肩带21之间的接触面积，从而提高使用舒适性。可选地，缓冲套由海绵制成。
在本实用新型的一些实施例中，如图4所示，第一固定结构22为滑 块结构222，滑块结构222滑动设置在靠背1的背面并能够沿靠背1的高度方向滑动；
固定时，滑块结构222覆盖在第一固定孔10上，肩带21穿过第一固定孔10，滑块结构222抵在靠背1的背面并限制肩带21与靠背1分离；
调节时，滑块结构222覆盖在第一调节孔11上并沿靠背1的高度方向滑动，肩带21穿过第一调节孔11并能够沿第一调节孔11移动。
其中，滑块结构222保持与靠背1的背面贴合并能够沿靠背1的高度方向上下滑动，即滑块结构222与靠背1在前后方向上相对固定，在上下方向上能够相对活动。滑块结构222的面积大于第一固定孔10和第一调节孔11的面积，当固定肩带21时，将滑块结构222滑动至覆盖在第一固定孔10上，此时肩带21穿过第一固定孔10，且滑块结构222抵在靠背1的背面，使得肩带21能够保持固定在第一固定孔10中的同时不会与靠背1分离，从而起到约束作用。当需要调整肩带21的高度时，使用者可将肩带21进行扭转并使得肩带21进入至第一调节孔11中，通过拉动肩带21使得肩带21能够沿第一调节孔11移动至不同高度的第一固定孔10中，同时滑块结构222也能够跟随肩带21的端部沿靠背1的高度方向上下移动。
在本实用新型的一些实施例中，如图4所示，靠背1的背面设有与第一固定孔10和第一调节孔11位置对应的滑槽19，滑块结构222滑动设置在滑槽19中。
其中，滑槽19沿靠背1的高度方向设置，且滑槽19设置在第一固定孔10和第一调节孔11的外周，通过滑槽19能够使得滑块结构222既能够沿靠背1的高度方向滑动，也能够限制滑块结构222沿前后方向移动，从而使得肩带21不能够与靠背1分离。
在本实用新型的一些实施例中，如图3所示，第一调节孔11沿靠背1的高度方向设置，第一调节孔11与第一固定孔10的中部连通。
其中，第一调节孔11与第一固定孔10的中部连通可以使得肩带21在旋转至第一调节孔11时更加容易。
进一步的，在固定时，肩带21处于其中一个第一固定孔10中，此 时肩带21大致与靠背1的表面平行，即能够使得肩带21与人体接触的面积较大，提高佩戴时的舒适性和安全性。当需要调整肩带21的高度时，由于肩带21为柔性带，因此使用者能够将肩带21旋转至大致与靠背1垂直，此时肩带21即可进入至第一调节孔11中并通过第一调节孔11将肩带21移动至其他不同高度的第一固定孔10中，以满足不同年龄段或身高的儿童进行使用。同时，本申请中多个第一固定孔10通过第一调节孔11连通，因此在调节肩带21的高度的时候，使用者无需将肩带21拆出，只需将肩带21沿第一调节孔11移动至不同的第一固定孔10中即可，使用调节更加便捷。
可选地，第一调节孔11还能够与第一固定孔10的端部连通。
可选地，在相邻的两个第一固定孔10中设置有一个第一调节孔11，相邻的两个第一调节孔11交错设置，即相邻的两个第一调节孔11不处于同一直线上。
在本实用新型的一些实施例中，如图6所示，靠背1上还设有第二固定孔12和第二调节孔13，多个第二固定孔12沿靠背1的高度方向间隔设置，第二调节孔13连通多个第二固定孔12，第二固定孔12设置在第一固定孔10的一侧。
具体地，如图6所示，第一固定孔10和第二固定孔12形状大小相同，且第一固定孔10和第二固定孔12平行，对应地，第一调节孔11和第二调节孔13的形状大小相同且相互平行。第一固定孔10和第二固定孔12分别处于靠背1不同的长度位置上，当需要调整两个肩带21之间的间距的时候，使用者能够将肩带21从第一固定孔10中拆出并装入至第二固定孔12中，从而实现调节两个肩带21之间的间距，以适应不同肩宽的乘坐者的需求。
同理，肩带21能够沿第二调节孔13移动至不同高度的第二固定孔12中，以实现调节肩带21的高度，通过设置第一固定孔10和第二固定孔12，能够同时实现肩带21的间距调节以及肩带21的高度调节，从而能够满足不同需求的乘坐者使用。
可选地，第二固定孔12和第二调节孔13可以设置多组，从而使得 肩带21间距的调整范围更加广。
在本实用新型的一些实施例中，如图6所示，第一调节孔11和第二调节孔13之间设有连通孔14，连通孔14连通第一调节孔11和第二调节孔13。
进一步的，第一固定孔10和第二固定孔12在横向上的位置和数量对应，第一固定孔10和第二固定孔12至少设置两个，通过设置连通孔14能够实现第一调节孔11和第二调节孔13之间的连通，当需要调整两个肩带21之间的间距时，使用者可以将肩带21沿连通孔14移动至第一调节孔11或第二调节孔13中，然后再将肩带21移动至第一固定孔10或第二固定孔12中。通过设置连通孔14能够实现调节肩带21的间距时无需将肩带21拆下重新安装，安装便捷简单。
再进一步的，如图6所示，相邻的两个第一固定孔10之间设有至少一个连通孔14，连通孔14连通第一调节孔11和第二调节孔13。
通过在两个第一固定孔10之间设置至少一个连通孔14能够实现在只需调整肩带21的间距时，使用者只需将肩带21移动至第一调节孔11或第二调节孔13中再将肩带21沿连通孔14移动调节位置即可，再将肩带21移动至调节前相同高度的第一固定孔10或第二固定孔12即可，使得调节更加方便。
可选地，连通孔14还可以只设置一个。
在本实用新型的一些实施例中，第一固定结构22为与肩带21穿出至靠背1背面一端连接的卡固结构221；
固定时，卡固结构221抵接在靠背1背面并限制肩带21与靠背1分离。
其中，乘坐者通过肩带21、腰带23和裆带25约束在靠背1的正面，当乘坐者在惯性作用下前移时带动肩带21向前动作，此时由于卡固结构221抵接在靠背1的背面，从而使得肩带21不能够进一步的向前移动，从而能够限制乘坐者前移。
在本实用新型的一些实施例中，如图9所示，卡固结构221包括限位面2211和拆卸面2212，限位面2211的面积大于第一固定孔10的面 积，拆卸面2212的面积小于第一固定孔10的面积；
肩带21与限位面2211连接，卡固结构221能够相对于肩带21活动；
固定时，卡固结构221旋转至限位面2211朝向第一固定孔10，限位面2211抵在靠背1上并限制肩带21与靠背1分离；
拆卸时，卡固结构221旋转至拆卸面2212朝向第一固定孔10使得卡固结构221能够穿过第一固定孔10并与靠背1分离。
进一步的，卡固结构221为板状结构，其中，由于肩带21为柔性带，因此卡固结构221能够旋转调整其位置。当肩带21被固定时，卡固结构221旋转至限位面2211朝向靠背1的背面，并且当肩带21受到外力前拉的时候，卡固结构221的限位面2211抵在靠背1的背面从而限制肩带21与靠背1分离。当需要将卡固结构221拆除时，旋转卡固结构221使得拆卸面2212朝向靠背1的背面，并调整卡固结构221使得卡固结构221对准第一固定孔10，此时卡固结构221即可以从第一固定孔10中穿出，从而使得肩带21与靠背1分离。
可选地，卡固结构221还可以是硬质板，肩带21与硬质板连接，固定时，硬质板抵在靠背1的背面从而限制肩带21与靠背1分离。
在本实用新型的一些可选实施例中，第一固定结构由肩带打结形成。
在本实用新型的一些实施例中，肩带21上设有用于调节肩带21长度的长度调节扣。通过肩带21调节扣能够对调节肩带21的长度，从而满足不同需求的乘坐者的使用。
可选地，第一固定结构22还可以是设置在靠背1的背面的卷收器，肩带21缠绕在卷收器中，当需要穿戴安全带2时可以将肩带21拉出，当乘坐者突然惯性前移时，卷收器能够限制肩带21拉出以限制乘坐者继续前移。
在本实用新型的一些实施例中，如图9所示，卡固结构221由多层肩带21折叠固定形成。
具体地，肩带21穿出靠背1背面的一端折叠后通过缝线或粘胶使得相邻的肩带21能够固定连接在一起，经过折叠后的多层肩带21不易变 形且体积变大，因此能够起到限制肩带21与靠背1分离。
在本实用新型的一些实施例中，如图8所示，卡固结构221包括固定层2213和活动层2214，固定层2213与活动层2214连接，活动层2214与肩带21连接，活动层2214具有折叠空间2215；
拆卸时，卡固结构221旋转至肩带21处于靠背1背面的部分收入至折叠空间2215内使得肩带21与活动层2214平齐，肩带21的截面与固定层2213的侧面形成限位面2211，旋转卡固结构221至限位面2211朝向第一固定孔10，使得卡固结构221能够穿过第一固定孔10并与靠背1分离。
较优地，固定层2213至少包括两层肩带21，从而使得固定层2213不易发生变形，使得卡固结构221能够牢固地抵在靠背1的背面。肩带21翻折至固定层2213的表面形成活动层2214。当固定时，卡固结构221旋转至与肩带21穿过第一固定孔10的部分垂直并使得卡固结构221覆盖在第一固定孔10上并抵贴在靠背1的背面，从而限制肩带21与靠背1分离。当需要将肩带21拆出的时候，将卡固结构221旋转90°使得肩带21处于靠背1背面的部分旋转至折叠空间2215内，此时肩带21与活动层2214平齐且刚好旋转至限位面2211朝向第一固定孔10，通过将肩带21向外拉出即可使得卡固结构221从第一固定孔10中抽出，从而实现肩带21与靠背1的分离。
在本实用新型的一些实施例中，如图2和图8所示，安全带2还包括腰带23，腰带23的端部设有第二固定结构24，靠背1上还设有第三固定孔15和第三调节孔16，腰带23穿过第三固定孔15或第三调节孔16；
多个第三固定孔15沿靠背1的长度方向间隔设置，第三调节孔16连通多个第三固定孔15；
固定时，腰带23穿过其中一个第三固定孔15并通过第二固定结构24限制腰带23与靠背1分离；
调节时，腰带23能够沿第三调节孔16移动至其他第三固定孔15中。
通过设置多个第三固定孔15从而使得两个腰带23之间的间距能够进行调整，以满足不同使用者的使用需求。且通过第三调节孔16能够在调节腰带23时无需将腰带23拆卸出来并重新安装，只需将腰带23沿第三调节孔16移动至不同的第三固定孔15中即可，调节方便快速。
其中，第二固定结构24与第一固定结构22结构相同，均为卡固结构221。
作为本实用新型的一个优选实施例，如图1所示，靠背结构包括靠背1和安全带2，其中安全带2为五点式安全带2，如图7所示，安全带2包括两组肩带21、两组腰带23、裆带25和卡扣结构26，卡扣结构26与裆带25固定连接，肩带21的一端与靠背1连接，另一端与卡扣结构26可拆卸连接，腰带23的一端与靠背1连接，另一端与卡扣结构26可拆卸连接。
其中，如图1-3所示，在靠背1的左右两侧分别各设置有一组第一固定孔10和第一调节孔11，多个第一固定孔10沿靠背1的高度方向间隔设置，且第一固定孔10为长孔，第一固定孔10靠近靠背1的纵向中线一端处于第一固定孔10远离靠背1的纵向中线一端的上方，因此第一固定孔10从内往外向下倾斜。第一调节孔11将多个第一固定孔10连通。
肩带21的端部从第一固定孔10或第一调节孔11中穿出至靠背1的背面，在靠背1的背面设置有第一固定结构22，其中，第一固定结构22为卡固结构221，卡固结构221为由多层肩带21折叠组成的卡固结构221。其中，卡固结构221包括限位面2211和拆卸面2212，限位面2211的面积大于第一固定孔10的面积，拆卸面2212的面积小于第一固定孔10的面积，因此当限位面2211朝向靠背1的背面时，限位面2211能够覆盖在第一固定孔10上并使得卡固结构221不能够从第一固定孔10中穿出，使得肩带21和靠背1之间不会分离。当拆卸面2212朝向第一固定孔10时，卡固结构221能够从第一固定孔10中穿出，使得肩带21能够与靠背1分离。
在本申请中，肩带21能够固定在不同高度位置的第一固定孔10中，以满足不同年龄段或身高的使用者使用，在调整肩带21高度的时候，使 用者无需将肩带21与靠背1拆卸分离，只需将肩带21沿第一调节孔11移动至不同高度的第一固定孔10中即可，调节方便简单。
