Description

安全带组及儿童汽车安全座椅
技术领域
本发明涉及一种缓冲装置，尤其涉及一种结构简单，成本低廉的安全带组。
背景技术
现有的儿童汽车安全座椅的安全带一般只是将其一端固定，另一端与座椅的带扣扣合；通过使用这种连接方式，当小孩乘坐于座椅上并面对突然的急煞车时，小孩的身体由于惯性作用继续向前冲出，安全带即紧拉小孩的身体，进而阻挡小孩向外飞出；而由于安全带不具备弹性，安全带对小孩身体的拉力是瞬间的，小孩受到安全带的拉力与冲击力相当，并且，由于小孩的骨络尚未发育到能完全抵受强大的冲击力，因此，小孩的身体极容易受到创伤。一般情况下，由于安全带是从胸前向肩膀跨越，当安全带阻挡小孩身体向前飞出时，头部仍然具有向前的惯性，因此，使用一般的安全带，小孩的胸骨及椎骨最容易受到伤害。
为了减少对小孩的伤害，一般在安全带上设置缓冲装置，但是目前所使用的缓冲装置结构复杂，使用不便，而且成本较高，并不能满足人们的使用要求，因此，需要一种结构简单，成本低廉的安全带组。
发明内容
本发明的目的在于提供一种结构简单，成本低廉的安全带组。
本发明的另一目的在提供一种使用方便、安全可靠、成本低廉的儿童汽车安全座椅。
为了实现上述目的，本发明提供的安全带组包括安全带及若干缓冲机构，所述缓冲机构可分离地将所述安全带长度方向上的任意两点连接，使所述安全带形成折叠部，当所述安全带受到时，所述缓冲机构吸收部分拉力后使连接的两点分离。
较佳地，所述缓冲机构为车缝线，所述车缝线将所述安全带长度方向上的任意两点连接。由于所述车缝线在受到一定的拉力时会被拉断，因此，利用所述车缝线不但能使所述安全带两点实现有效连接，形成折叠部，而且在所述安全带缓冲时抵消一定冲击力后再被拉断，从而再次使所述安全带拉紧抵消冲击力，与一般的缓冲器相比，结构简单，加工方便，极大地降低了生产成本。
较佳地，所述缓冲机构包括公扣及母扣，所述公扣及母扣分别设置于所述安全带上，且可分离地相互扣合。通过使所述公扣及母扣扣合，从而使所述安全带形成折叠部，当缓冲时，所述公扣及母扣分离，从而使折叠部伸展并拉紧，从而抵消冲击力，结构简单，再次扣合公扣及母扣可重复使用，非常用方便，且极大地降低了生产成本。
较佳地，所述缓冲机构为魔术贴，所述魔术贴包括毛绒面及勾体面，所述毛绒面及勾体面分别设置于所述安全带上，且可分离地相互粘合。通过使所述毛绒面及勾体面相互粘合，使所述安全带形成折叠部，在缓冲时，利用冲击力克服魔术贴的毛绒面及勾体面的粘合力，从而使毛绒面及勾体面相互分离而抵消一定的冲击力，达到缓冲的目的。
具体地，所述安全带为编织带。
较佳地，所述缓冲机构位于所述安全带的中间部位。
一种儿童汽车安全座椅，包括座椅本体、跨带、两肩带、带扣、安全带调节器及至少一所述安全带组，所述跨带及安全带调节器设置于所述座椅本体的前端上，两所述肩带的一端分别与所述跨带连接，另一端分别与所述带扣一端连接，所述安全带组设置于所述带扣及安全带调节器之间。
一种儿童汽车安全座椅，包括座椅本体、跨带、两肩带、带扣、安全带调节器及至少一所述安全带组，所述跨带及安全带调节器分别设置于所述座椅本体的前端，两所述肩带的一端分别与所述跨带连接，另一端分别与所述带扣一端连接，所述安全带组数量为二，且分别设置于所述带扣与肩带之间。
与现有技术相比，由于本发明通过在所述安全带上设置所述缓冲机构，并使所述缓冲机构可分离地将安全带上的两点连接而形成折叠部，因此，在需要缓冲时，所述安全带在起初阶段拉紧，进而抵消一定冲击力，当所述安全带继续拉紧到一定程度后，所述缓冲机构因受力过大而自动释放所述安全带的两连接点，进而使所述折叠部伸展，当完全伸展后，所述安全带再次拉紧而再抵消一定的冲击力，从而起到缓冲的作用，整个安全带组不但结构简单、使用方便、安全可靠，而且成本低廉，可广泛使用。

具体实施方式
本发明安全带组，安装于儿童汽车安全座椅200上，如图1至图3所示为本发明实施例一，所述安全带组100包括安全带1及若干缓冲机构2，所述安全带1为一种尼龙编织带，所述缓冲机构2可分离地将所述安全带1长度方向上的任意两点连接，使所述安全带1形成折叠部11，所述折叠部11处于所述安全带1的中部位置，当所述安全带1受到拉力时，所述缓冲机构2吸收部分拉力后使连接的两点分离，进而带动所述折叠部11伸展，从而使所述安全带1再次拉紧。
所述儿童汽车安全座椅200具有座椅本体201、两肩带202、带扣203、安全带调节器204及跨带205，所述跨带205及安全带调节器204分别设置于所述座椅本体201的前端上，两肩带202的一端分别与座椅本体201上的跨带205卡合连接，另一端分别向后穿过所述座椅本体201的靠背201b，并与座椅本体201背部的带扣203连接。所述安全带组100一端与所述带扣203固定，另一端与安全带调节器204连接，并从椅座201a前端穿出，藉由拉动所述安全带组100另一端，可进行肩带202长度调整。
具体地，本实施例的所述缓冲机构2位于所述安全带1的中间部位，且为车缝线2，所述车缝线2将所述安全带1长度方向上的任意两点连接，该两连接点之间的安全带折叠形成折叠部11。当儿童乘坐于座椅本体201上受到突于其来的急煞车或撞击时，身体会拉扯肩带202，当所述安全带1受到冲击力后，拉力超过所述车缝线2的作用力后，所述车缝线2被拉断。在此过程中，所述车缝线2则抵消一部分拉力，因而达到缓冲的效果，且可避免儿童在撞击过程中因肩带202施予的反作用力而造成的伤害。由于所述车缝线2在受到一定的拉力时会被拉断，因此，利用所述车缝线2不但能使所述安全带1的两点实现有效连接，形成折叠部11，而且在所述安全带1受到拉力时抵消一定冲击力后再被拉断，从而再次使所述安全带1拉紧而继续提供将儿童固定于儿童汽车安全座椅200的功用。并且，所述安全带1上可设置多道所述车缝线2，从而可进行多次缓冲。与一般的缓冲器相比，结构简单，加工方便，极大地降低了生产成本。
如图4所示为本发明实施例二，本实施例的安全带组100’亦安装于实例一所述的儿童汽车安全座椅200上；与实施例一的所述安全带组100不同的是，本实施例的安全带组100’包括安全带1’及缓冲机构2’，所述缓冲机构2’包括公扣21’及母扣22’，所述公扣21’及母扣22’分别设置于所述安全带1’上，且可分离地相互扣合。当儿童乘坐于座椅本体201上受到突于其来的急煞车或撞击时，身体会拉扯肩带202，所述肩带202则拉紧所述安全带组100’，此时，所述安全带1’受到肩带202的拉力，当拉力超过所述公扣21’及母扣22’的扣合力后，所述公扣21’及母扣22’被拉脱，在此过程中，所述安全带组100’则抵消一部分拉力，因而达到缓冲的效果，，且可避免儿童在撞击过程中因肩带施予的反作用力而造成的伤害。通过使用所述公扣21’及母扣22’扣合，使所述安全带1’形成折叠部11’，当缓冲时，所述公扣21’及母扣22’分离，从而使所述折叠部11’伸展并拉紧，从而抵消一定冲击力后再被拉脱，最后再次使所述安全带1’拉紧而继续提供将儿童固定于儿童汽车安全座椅200的功用，结构简单，再次扣合公扣21’及母扣22’可重复使用，非常方便，且极大地降低了生产成本。当然，本实施例的安全带组100’也可在所述安全带1’上设置多个，从而进行多次缓冲，降低煞车时冲击力对身体的损害。
如图5所示为本发明实施例三，所述安全带组100”安装于儿童汽车安全座椅200上，包括安全带1”及缓冲机构2”，所述儿童汽车安全座椅200与实施例一的相同，不同在于所述缓冲机构2”为魔术贴，所述魔术贴包括毛绒面21”及勾体面22”，所述毛绒面21”及勾体面22”分别设置于所述安全带1”上，且可分离地相互粘合。通过使所述毛绒面21”及勾体面22”相互粘合，使所述安全带1”形成折叠部11”，在缓冲时，利用冲击力克服魔术贴的毛绒面21”及勾体面22”的粘合力，从而使毛绒面21”及勾体面22”相互分离而抵消一定的冲击力，达到缓冲的目的。
另外，如图6所示，本发明实施例四，所述安全带组100安装于儿童汽车安全座椅200上时，所述安全带组100还可以分别设置于所述带扣203与肩带202之间，即在肩带202上设置所述缓冲机构2，进而设置于座椅本体201背部的两所述肩带202上，当所述肩带202受到冲击力后藉由缓冲机构2逐渐抵消冲击力，达到缓冲的目的，与上述实施例的缓冲方式相同，在此不再重复描述。并且，上述安全带组100并不仅仅用于儿童座椅上，还可以应用于一般的汽车座椅上，缓冲原理与上述描述的一致。
由于本发明通过在所述安全带1上设置所述缓冲机构2，并使所述缓冲机构2将安全带1上的两点连接而形成折叠部11，因此，在撞击的过程中，安全带1在起初阶段受力拉紧，进而抵消一定冲击力，当所述安全带1继续拉紧到一定程度后，使所述缓冲机构2受力而使所述安全带1的两连接点分离，藉由所述安全带1的状态改变达到缓冲功效，由于两连接点分离后使所述折叠部11伸展，因此能继续提供安全带1固定幼儿的功能，整个安全带组100不但结构简单、使用方便、安全可靠，而且成本低廉，可广泛使用。
以上所揭露的仅为本发明的较佳实例而已，当然不能以此来限定本发明之权利范围，因此依本发明申请专利范围所作的等同变化，仍属于本发明所涵盖的范围。
