Description

座椅辅助防护装置和儿童安全座椅 技术领域
本发明涉及配合安全带使用的座椅辅助防护装置以及婴幼儿使用的儿童安 全座椅， 在发生意外时， 能够对头部进行约束， 避免成人及儿童的头部发生过 度前倾或者扭动， 从而保护颈椎和头部。 背景技术
为了保证坐在座椅上的乘客的安全， 在包括汽车在内的各种交通工具上， 以及游乐设施的座椅上都配备用于约束乘客躯干的安全带， 在发生意外时约束 人的身体， 以保护人身安全。 现有技术的缺陷在于， 在发生意外的时候， 安全 带只能牢牢地将乘客的身体的躯干部分固定在座椅上， 而人的头部仍然会因为 惯性而发生前倾或者扭动， 从而伤害头部以及颈椎。
此外， 为了方便婴幼儿乘坐交通工具， 现有技术中， 还设计了适合婴幼儿 使用的儿童安全座椅， 将儿童安全座椅固定在汽车本身的座椅上， 再用安全带 把婴幼儿固定在儿童安全座椅里面， 可以防止婴幼儿被抛甩出位。 同样地， 现 有技术的儿童安全座椅只是固定住了婴幼儿的身体的躯干部分， 而当意外发生 时， 由于惯性婴幼儿的头部还是会发生前倾或扭动， 这样会使颈椎和头部受到 伤害。 与成人相比， 头部和颈椎更为娇嫩的婴幼儿， 更容易受到伤害， 并且受 到的伤害程度更为严重。 发明内容
本发明的第一个目的是提供一种配合安全带使用的座椅辅助防护装置， 在 发生意外时， 避免乘客的头部过度前倾或者扭动而损伤到颈椎和头部。
本发明的第二个发明目的是提供一种供幼儿乘坐的儿童安全座椅， 在发生 意外时， 避免婴幼儿的头部过度前倾或者扭动而损伤到颈椎和头部。
为了实现上述的第一个目的， 本发明提供了一种座椅辅助防护装置， 座椅 辅助防护装置， 包括与座椅连接的头枕和固定于所述头枕上的用于约束乘客头 部的头部防护装置。
作为优选方案， 所述头部防护装置为护栏， 所述的头枕两侧设有侧靠枕， 其中一个侧靠枕的下端设有开口， 所述护栏与该侧靠枕固定连接并在未使用时 存储在侧靠枕内； 使用时， 所述护栏从侧靠枕内取出， 并通过卡扣固定连接在 另一个侧靠枕上。
进一步地， 所述的侧靠枕通过第一转轴与头枕转动连接。
作为另外一种优选方案， 所述头部防护装置为 U形的护翼， 所述护翼包括 前端的防护部和分别连接在所述防护部两端的侧翼部； 所述的头枕两侧设有滑 道， 所述侧翼部的端部设有滑杆， 所滑杆与所述滑道配合在所述滑道内滑动， 所述滑杆通过定位部件固定在所述滑道的适当位置上。
进一步地， 所述定位部件为设置在所述滑杆端部的旋钮， 所述旋钮与所述 滑杆通过螺纹连接。
作为另外一种优选方案， 所述的防护装置为圆圈状的汗带， 所述头枕的上 端设有容置所述汗带的开口， 所述汗带通过一端固定在所述开口内的连接带与 所述头枕连接。
为了实现上述的第二个目的， 本发明提供了一种儿童安全座椅， 包括儿童 安全座椅和安全带，在儿童安全座椅内侧的上部设有用于约束婴幼儿头部的头部 防护装置。
作为优选方式， 所述的儿童安全座椅上还设有五点式安全带。
作为优选， 所述的头部防护装置有两种具体实施方式：
头部防护装置的第一种实施方式是： 头部防护装置为与所述儿童安全座椅 连接的防护带。 作为优选， 所述的防护带收藏槽与防护带的交接处设有第二转 轴， 防护带通过第二转轴与所述儿童安全座椅转动连接， 防护带转动而进入或 退出防护带收藏槽。
头部防护装置的第二种实施方式是： 头部防护装置为与所述儿童安全座椅 连接的防护罩。 作为优选， 所述儿童安全座椅上固定连接有防护罩外壳， 所述 的防护罩和防护罩外壳之间设有第二转轴， 防护罩通过第二转轴与防护罩外壳 转动连接， 从而实现防护罩进入或者退出防护罩外壳。
作为进一步地优选， 所述的防护带或防护罩的表面设有柔性保护层。 本发明的有益效果在于： 本发明的座椅辅助防护装置， 通过头部防护装置 约束乘客的头部， 限制乘客的头部位移， 防止头部过度前倾或扭动而损伤到颈 椎。 本发明的儿童安全座椅上的头部防护装置应与安全带配合使用， 否则发生 意外时， 不能有效保护婴幼儿的头部和颈椎。 在使用时， 旋转防护带或防护罩， 使其移到儿童额头的位置， 起到限位的作用， 婴幼儿的头部被防护带或防护罩 所固定， 避免交通工具发生意外后婴幼儿的头部过度前倾或过度扭动而损伤到 颈椎。 附图说明
