Description

一种机动车碰撞安全靠背
技术领域
本发明属于机动车安全装置领域，特别涉及保护后排乘员头、颈部安全的一种机动车碰撞安全靠背。
背景技术
机动车座椅是乘员保护的重要组成部分。在机动车正面碰撞中，佩戴安全带的后排乘员在惯性力的作用下向前冲撞，后排乘员的头部会撞击到前排座椅的头枕上，导致头部、颈部等部位受到不同程度的伤害。
发明内容
为了克服现有机动车座椅的缺陷，本发明提供一种机动车碰撞安全靠背，在机动车正面碰撞时能对后排乘员头、颈部进行保护。
为达到上述目的，本发明采用以下技术方案：一种机动车碰撞安全靠背，包括头枕、头枕导杆、靠背骨架、导套、横圆杆、上横板、下横板、弹簧及支撑杆；
所述靠背骨架的顶端等间距开有两滑槽，靠背骨架内部为中空开放的腔室；所述腔室内部设有缓冲部件组；所述缓冲部件组包括导套、横圆杆、上横板、下横板、弹簧及支撑杆；所述导套顶端设有盲孔；所述头枕导杆下端插入盲孔，头枕导杆上端与头枕固定连接；所述导套底端与上横板固结；所述上横板的下端按照一定的间距平行设有下横板；所述上横板与下横板之间固定有两个弹簧；所述下横板的底部中间位置焊接有支撑杆；所述支撑杆另一端与靠背骨架固结。
进一步，所述头枕导杆下端可自由活动，用于调节头枕的上下高度。
进一步，所述弹簧能够在一定压力作用下发生弹性压缩变形。
进一步，所述导套从上至下分为三段，所述第一段导套插入靠背骨架顶端的滑槽中，并留有一定间隙；第一段导套与第二段导套之间为钝角，第二段导套与第三段导套之间为直角，第一段导套与第二段导套之间的弯折处开有供横圆杆插入的一对通孔；所述通孔同一水平线的靠背骨架对称两侧壁上设有一对圆形凹槽，使得所述横圆杆的左右两端固定插入。
本发明的优点在于：在机动车正面碰撞中，当后排乘员头部撞击前排座椅头枕，并且撞击强度较大，导致其头部、颈部受到伤害时，前排座椅头枕利用此撞击力，向前转动一定角度，从而缓冲后排乘员头部与前排座椅头枕的撞击力，有效减轻后排乘员伤害。当机动车正面碰撞结束后，前排座椅头枕恢复原始位置，正常保护前排乘员头部、颈部安全。

具体实施方式
以下结合附图和具体实施方式对本发明作进一步详细说明，但本发明的保护范围并不限于此。
如图1、2所示，一种机动车碰撞安全靠背，包括头枕1、头枕导杆2、靠背骨架3及缓冲部件组；靠背骨架3的顶端等间距开有两滑槽，靠背骨架3内部为中空开放的腔室；腔室内部设有缓冲部件组，缓冲部件组包括导套4、横圆杆5、上横板6、下横板7、弹簧8及支撑杆9；导套4顶端设有盲孔，头枕导杆2下端插入盲孔，头枕导杆2上端与头枕1固定连接，头枕导杆2下端可自由活动，用于调节头枕1的上下高度；导套4底端与上横板6固结(图3)，上横板6的下端按照一定的间距平行设有下横板7；上横板6与下横板7之间固定有两个弹簧8，弹簧8能够在一定压力作用下发生弹性压缩变形；下横板7的底部中间位置焊接有支撑杆9(图4)，支撑杆9另一端与靠背骨架3固结。
导套4从上至下分为三段，第一段导套插入靠背骨架3顶端的滑槽中，并留有一定间隙；第一段导套与第二段导套之间为钝角，第二段导套与第三段导套之间为直角，第一段导套与第二段导套之间的弯折处开有供横圆杆5插入的一对通孔，通孔同一水平线的靠背骨架3对称两侧壁上设有一对圆形凹槽，使得横圆杆5的左右两端固定插入。
在机动车正面碰撞中，佩戴安全带的后排乘员在惯性力的作用下向前冲撞，当后排乘员的头部撞击前排座椅头枕1，并且撞击强度较大，导致后排乘员头部、颈部伤害时，弹簧8在上横板6的压力作用下发生弹性压缩变形，这样上横板6与导套4的固定连接体(图3)就绕靠背骨架3中的横圆杆5向前转动一定角度，同时头枕导杆2、头枕1向前转动一定角度，从而缓冲后排乘员头部与前排座椅头枕1的碰撞，有效减轻后排乘员头部、颈部受到的伤害。当机动车正面碰撞结束后，后排乘员在安全带的拉力作用下向后位移，上横板6失去后排乘员头部撞击力的作用，不再给弹簧8施加压力，此时弹簧8伸张，恢复原有形状，反作用于上横板6，使其与导套4的固定连接体(图3)绕靠背骨架3中的横圆杆5恢复原始位置，同时头枕导杆2、头枕1恢复原始位置，正常保护前排乘员头部、颈部安全。
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本行业的技术人员应了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内，本发明要求保护范围由所附的权利要求书其等效物界定。
