Description

用于汽车座椅的多功能安全装置及汽车安全座椅 技术领域
本发明涉及一种用于汽车座椅的安全防护装置， 尤其是涉及一种多功能安 全装置及安装有该安全装置的汽车座椅。
背景技术
随着当今社会经济水平逐渐提高，拥有各类汽车的人越来越多， 而汽车上的 安全带则成了重要的配件之一，能给车上乘客在遇到突发事故时提供安全保障措 施。
在二十世纪五十年代， 沃尔沃工程师经过努力， 汽车安全带才发展成今天我 们熟知的现有技术方案。 中国专利文献 CN201040516Y公开了一种汽车安全带， 在 CN100486840C中， 也公开了一种安全带装置， 此外在 EP2492157A1中， 也 披露了一种用于座椅的安全带系。
但是，上述专利文献中的安全带装置一般只能用于给坐姿状态下的乘客提供 安全保障， 当乘客处于躺卧状态时， 尤其是两人座以上座椅， 乘客需要休息时， 或因身体状况需要导致必须采用躺卧状态时，或者是在座椅上放置物品时， 由于 安全带的锁扣位置和皮带安装位置的限制，使其无法给处于躺卧状态的乘客或放 置物品不稳固时提供安全防护，给乘客安全及物品稳固造成了一定的隐患。解决 该类问题的方案往往考虑再行增加安全绳索等单独装置， 但其设置将会显繁琐， 增加成本以及影响乘坐的舒适性。同时将可能会造成座椅上装置过多，铺设复杂， 乘客使用座椅的诸多不便， 或者在座位上放置物品，压挤安全带会造成安全绳索 有一定磨损， 降低了安全绳索的安全防护性能。
本领域技术人员经过多年研究发现，汽车安全带装置应当在适当的区域吸收 撞击力， 同时安全带还须方便使用， 利于调整。
人们常说最简单的往往是最好的， 因此， 有必要研究出一种多功能的汽车座 椅安全装置，在节约成本、简单方便的前提下，用最精简的装置，达到最多功能， 最高效率的技术效果，对现有汽车安全带进行改进，使其既能给处于坐姿状态下 的乘客正常使用， 又能给处于躺卧状态下的乘客提供安全保障，还可以在座椅空 置时稳固的放置行李物品， 又可以在车内形成立体防护状态， 在紧急情况下， 充 当最方便抓握的扶手， 以达到五功能为一体的一种有效安全装置。
发明内容
本发明要解决的技术问题是提供一种提高安全带的安全防护性能，简单方便 适用， 结构精简， 功能多， 效率高， 使用舒适， 并可提高安全防护性能， 使得处 于坐姿状态下，休息状态下的因特殊身体状况需要只能平躺或侧卧而处于躺卧状 态下的乘客都有安全保障，还可以在汽车座椅空置时稳固的放置行李物品的用于 汽车座椅的多功能安全装置。
为了解决上述问题，本发明采用的技术方案是：该多功能安全装置包括卷收 器， 还包括有安全带， 所述安全带上活动套装有第一卡扣， 还包括有设置于汽车 座椅背与坐垫连接处、 在乘客坐姿状态下与第一卡扣相配合卡合的第一卡扣槽； 以及设置于坐垫底部或靠近坐垫、在乘客躺卧状态下或放置物品时与第一卡扣相 配合卡合的第二卡扣槽，且安全带设置的长度可以达到使得第一卡扣与第二卡扣 槽相配合卡合。
采用上述技术方案的多功能安全装置，能够同时实现五种功能， 即在乘客坐 姿状态下，通过活动安装在安全带上的第一卡扣与设置于汽车座椅背与坐垫连接 处的第一卡扣槽相配合卡合， 可以保证乘客在坐姿状态下的安全； 另外， 当乘客 处于躺卧状态下时，第一卡扣与设置于坐垫底部或靠近坐垫的第二卡扣槽相配合 卡合，保证了乘客在躺卧状态下的安全，另外在座椅放置物品时起到稳固安全作 用， 又可以在车内形成立体防护状态， 在紧急情况下， 充当最方便抓握的扶手， 其产生的有益效果是， 即可在正常坐姿状态下使用，又可以保证了乘客在卧睡状 态下的安全或放置物品时稳固，提高了乘客在卧睡状态下，或者特殊情况下必须 平躺、 侧卧在座椅上时， 安全带对于汽车座椅上的乘客的安全防护性能， 同时， 由于安全带可伸长拉至座椅前端，形成了一个立体空间防护，可在紧急情况时做 为车内最方便抓稳， 多方位可抓的部件， 起到相当于扶手的作用， 另外， 进一步 的充分利用了座椅空置时的空间稳固放置物品，且由于使用的需要往往在汽车座 椅上会放置体积较大的物品， 如行李箱包、被子等， 由于现有的安全带装置主要 是对于采用坐姿的乘客设计的，无法有效的适用到这些物品上，起不到稳固的作 用，本发明的技术方案考虑到了这一点，通过研究并经过多次试验在较大物品放 置座位上的状态和重心， 采用本发明的多功能安全装置可以最稳固、可靠、方便 的使上述行李物件在车内达到最稳固的状态。
且同时该多功能安全装置结构精简， 不需铺设过多装置和铺设过多绳带，不 会因为乘客卧睡或放置物品而长期压挤造成磨损。本发明的结构设置，充分利用 现有安全带的结构进行多功能改进，加工工艺简单，节约成本， 多功能，效率高， 使传统安全带起到多功能作用，安全便捷，提高了安全带的使用效率，不易磨损， 延长了安全带的使用寿命， 同时更确保了使用者的安全性和舒适性相结合。
此外，本发明的多功能安全装置可供汽车厂商选装选用， 既无需增加更多的 成本，也无需对原有汽车构造进行较多的改进， 又可以增加汽车的功能性和舒适 性， 提高安全性， 并为本汽车增加了多次设置功能， 提高了乘坐的安全性， 舒适 性， 也可以提高驾驶的安全性，如防止在行驶中座椅上较大物品的滑落移动而影 响驾驶安全。这些都还将合法选用本安全装置的汽车厂商以较小的成本改进而亮 点和提高客户的欢迎度。
作为本发明的进一步改进，所述安全带一端固接在靠近汽车座椅偏下方侧面 的车体上； 另一端与设置在汽车座椅侧面的车体内的卷收器相连接， 由汽车座椅 偏上方的车体侧面导出口拉出，这样的结构设置，扩展了座椅上乘客的活动空间， 其次， 更加稳固了安全带， 紧紧的将安全带固定住， 使其不易发生移位。
作为本发明的进一步改进，所述安全带一端固接在所述汽车座椅背侧面或后 面偏下方处； 另一端与设置在汽车座椅内或座椅后的卷收器相连接， 由汽车座椅 侧面或后面偏上方导出口拉出， 采用这样的结构， 其产生的有益效果是， 方便乘 客操作， 更加便利。 同时， 安全带在使用状态下将更加贴合， 舒适和稳固。
作为本发明的进一步改进，所述安全带一端通过汽车座椅背内或座椅背后左 下方 D点固接在汽车座椅上； 另一端由设置在汽车座椅背内或座椅背后的左上 方 C 点拉出， 即安全带一端是固定的， 另一端是不固定的， 其产生的有益效果 是， 更进一步的方便了乘客系扣安全带， 在其不用解卸安全带状态时， 安全带不 会占用乘客移动的空间。
作为本发明的进一步改进， 所述安全带上还活动套装有第二卡扣， 在第一 卡扣与第二卡扣槽相配合卡合的状态下， 该第二卡扣可与第一卡扣槽相配合卡 合。 在乘客躺卧状态下， 需要将第一卡扣与第二卡扣槽相配合卡合，使其安全带 卡住乘客的重心位置， 使其不至于发生意外事故， 但是， 我们还必须考虑到另一 种情况， 某些乘客重心位置不适合被安全带卡住， 因此， 在安全带上还活动套装 有第二卡扣， 第二卡扣可与第一卡扣槽相配合卡合， 这样， 安全带卡住了乘客的 大约中间位置， 而并不是身体的重心部位， 这样， 方便了特殊乘客， 同时也节约 了卡扣槽的使用。
作为本发明的进一步改进，所述第二卡扣槽安装于坐垫横向长度方向上，距 离坐垫左端或右端的约三分之一处。
将第二卡扣槽安装于坐垫横向长度方向上，距离坐垫左端或右端的约三分之 一处，汽车座椅，尤其是座椅或长条椅一般都有可供两位或两位以上乘客乘坐的 座位， 即两个或两个以上座位， 这样才能保证乘客可用作躺卧， 这样， 将坐垫分 成三等分，第二卡扣槽安装在距离坐垫左端或右端的大致三分之一处，其产生的 有益效果是，在乘客处于躺卧状态下时，多动能安全带能够缠绕乘客身体大致重 心位置处， 使得乘客不会因为汽车的急停而出现安全事故。
作为本发明的进一步改进，所述第二卡扣槽还连接有伸缩带，第二卡扣槽可 在伸缩带长度方向内任意移动，伸缩带本身也可以具有伸缩功能，使得在安全带 长度不够的情况下，用于调节，其产生的有益效果是使得第一卡扣与第二卡扣槽 卡合更加方便操作。
作为本发明的进一步改进，所述坐垫下设有座椅支撑座架，所述座椅支撑座 架上还设有可内置隐藏第二卡扣槽的第一隐藏口，第二卡扣槽可以通过伸缩带安 装在座椅支撑座架上，位于靠近坐垫的位置，但是第二卡扣槽的位置不限于安装 在座椅支撑座架上， 其他任何靠近坐垫的位置都是可以的。
作为本发明的进一步改进， 该伸缩带的连接端固装在第一隐藏口内， 这样， 可将伸缩带附带第二卡扣槽一同放入隐藏口， 美观， 扩展了乘客活动空间。
作为本发明的进一步改进，所述坐垫底部的外侧部上还设有可内置隐藏第二 卡扣槽的第二隐藏口。
作为本发明的进一步改进， 该伸缩带的连接端固装在第二隐藏口内。
第二卡扣槽连接有伸缩带，伸缩带的连接端固装在坐垫下方的座椅支撑座架 上；所述座椅支撑座架上或坐垫底部的外侧部上还设有可内置隐藏第二卡扣槽的 ' 隐藏口。 第二卡扣槽可以直接安装， 也可以连接伸缩带，然后将伸缩带的连接端固装 在坐垫下方的座椅支撑座架上， 该座椅支撑座架所起的作用主要是用于支持坐 垫； 座椅支撑座架上还设有可内置隐藏第二卡扣槽的隐藏口， 这样， 在不用安全 带时， 可将连接有伸缩带的第二卡扣槽塞内在隐藏口内， 使其内置隐藏， 既美观 又不占用空间； 另外， 还可以的， 在坐垫底部的外侧部上也可设有可内置隐藏第 二卡扣槽的隐藏口， 这样会更美观， 更利于扩展乘客活动空间。
第二卡扣槽连接有伸缩带，坐垫下方具有座椅支撑座架，所述座椅支撑座架 上或坐垫底部的外侧部上还设有可内置隐藏第二卡扣槽的隐藏口，该伸缩带的连 接端固装在第二隐藏口内。
将伸缩带的连接端固装在隐藏口内，这样的结构设置，其产生的有益效果是， 在不用第二卡扣槽时， 使得从外面看， 该带有伸缩带的第二卡扣槽更加隐蔽， 更 加节约了车内的空间方便乘客挪位， 不会挂住衣裤。
作为本发明的进一步改进，所述安全带上还设有调节扣，其产生的有益效果 是， 可以根据乘客的体型调节安全绳带的长度。
本发明要解决的另一个技术问题是，提供一种安装有多功能安全装置的汽车 座椅， 该汽车座椅能够防护处于坐姿状态下和躺卧状态下乘客的安全。
为解决上述技术问题，本发明采用的技术方案是， 该汽车座椅包括相互连接 的汽车座椅背与坐垫，将前述的多功能安全装置设置于汽车座椅背左右两侧，在 乘客使用时，无论是坐姿状态还是躺卧状态， 都可形成立体防护区域的一体化汽 车座椅。
将上述的多功能安全装置设置于汽车座椅背左右两侧， 其产生的有益效果 是， 当乘客处于躺卧状态时， 其重心位置和腿部都有安全绳带缠绕， 且无论乘客 头部朝向哪一边，保护了乘客在躺卧状态下的安全；将多功能安全装置应用于或 者说设置在汽车座椅上， 效果更好，它能够籍着卷收器内的感应器于制动时作出 反应， 收紧安全带， 将多功能安全装置形成的立体防护区域收紧、 收实， 起到束 缚和阻挡作用， 加强保护力。
作为本发明的进一步改进，所述汽车座椅背的中间位置处还设置有多功能安 全装置， 该多功能安全装置包括安全绳带；所述安全绳带包括与汽车座椅背相连 接的连接端， 还包括有自由端， 所述自由端安装有第三卡扣； 在乘客坐姿状态下 时，该第三卡扣与安装于坐垫和座椅背连接处的第三卡扣槽相配合卡合，在乘客 躺卧状态下时， 该第三卡扣与安装于坐垫底部的第四卡扣槽相配合卡合。
在汽车座椅背的中间位置处设置有安全带，其产生的有益效果是，有利于更 进一步防护乘客在坐姿状态下和躺卧状态下的安全，同时增加了座椅上乘坐的乘 客人数。
作为本发明的进一步改进，所述第四卡扣槽还连接有第二伸缩带，所述第二 伸缩带固装在坐垫下方的座椅支撑座架上；所述座椅支撑座架上还设有可内置隐 藏第四卡扣槽的第三隐藏口。
作为本发明的进一步改进，所述第四卡扣槽还连接有第二伸缩带，坐垫下方 具有座椅支撑座架，所述座椅支撑座架上还设有可内置隐藏第四卡扣槽的第四隐 藏口， 第二伸縮带的连接端固装在第四隐藏口内。
作为本发明的进一步改进，所述安全绳带的连接端连接在汽车座椅背的上端 位置 A处或连接在坐垫和座椅背连接处之间的位置 B处。
将安全绳带的连接端连接在座椅背的上端位置 A处， 其产生的有益效果是， 在乘客处于坐姿状态下时，安全绳带将从肩部一直往下缠绕，整个上半身都处于 安全带的保护范围之下；此外，将安全绳带的连接端连接坐垫和座椅背连接处之 间的位置 B处， 其产生的有益效果是， 缩短了安全绳带的长度， 节约了成本， 另外， 当在乘客处于躺卧状态下时， 安全绳带相对缠绕乘客更紧凑， 有利于更进 一步保护乘客在躺卧状态下的安全。
采用本发明技术方案的多功能安全装置和汽车座椅，节约成本，加工工艺简 单， 装置可以同时具备五种功能， 乘客坐卧时都更加方便舒适、 安全； 有效的利 用了汽车座椅的空间， 还可在需要时稳固的放置物品， 安全带的使用寿命长； 本 发明装置可适用于各类型安全带装置，包括但不限于普通汽车安全带装置，预警 式安全带装置， 纯机械式安全带装置， 电动、 电子式控制安全带装置等； 此外， 对于汽车厂商来说， 选用本发明的多功能安全装置， 具有明显的商业优势， 有助 于其在商业上取得成功。

具体实施方式
如图 1所示，该用于汽车座椅的多功能安全装置包括卷收器，还包括安全带 1， 所述安全带 1上设有可调节安全带 1长度的调节扣 11 (如图 3所示）， 所述 安全带 1上活动套装有第一卡扣 2， 还包括有设置于汽车座椅背 4与坐垫 5连接 处、 在乘客坐姿状态下与第一卡扣 2相配合卡合的第一卡扣槽 3; 以及设置于坐 垫 5底部或靠近坐垫 5， 在乘客躺卧状态下或放置物品时与第一卡扣 2相配合卡 合的第二卡扣槽 6， 且安全带 1设置的长度可以达到使得第一卡扣 2与第二卡扣 槽 6相配合卡合， 第二卡扣槽 6 (如图 4所示）安装于坐垫 5横向长度方向上， 距离坐垫 5左端或右端的约三分之一处。
将安全带 1 的两端固接在靠近汽车座椅侧面的车体上， 还可以的， 如图 7 所示，将安全带 1两端固接在所述汽车座椅背 4侧面，安全带 1两端分别通过汽 车椅背 4左上方 C点 401和左下方 D点 402固接在汽车座椅 101上。 安全带 1上还活动套装有第二卡扣 102， 在第一卡扣 2与第二卡扣槽 6相配 合卡合的状态下， 该第二卡扣 102可与第一卡扣槽 3相配合卡合， 使用时， 当乘 客需要躺卧，将第一卡扣 2与第二卡扣槽 6相配合卡合，若是重心位置不适合卡 住的乘客，可再将第二卡扣 102可与第一卡扣槽 3相配合卡合，这样也能很好的 保护乘客的安全。
进一步的， 第二卡扣槽 6还连接有伸缩带 7， 所述伸缩带 7的连接端 701固 装在坐垫 5下方的座椅支撑座架 8上；座椅支撑座架 8上还设有可内置隐藏第二 卡扣槽 6的第一隐藏口 9， 如图 5所示； 如图 6所示， 还可以将可内置隐藏第二 卡扣槽 6的第一隐藏口 9设置在坐垫 4底部的外侧部上。
在坐垫 5下方具有座椅支撑座架 8的情况下，第二卡扣槽 6连接有伸缩带 7， 座椅支撑座架 8上可设有可内置隐藏第二卡扣槽 6的第二隐藏口 10，该伸缩带 7 的连接端 701固装在第二隐藏口 10内； 当然， 也可以将内置隐藏第二卡扣槽 6 的第二隐藏口 10设置于坐垫 4底部的外侧部上， 该伸缩带 7的连接端 701固装 在第二隐藏口 10内， 如图 6所示。
如图 2所示， 该汽车座椅包括相互连接的汽车座椅背 4与坐垫 5， 将前述多 功能安全装置设置于汽车座椅的左右两侧，在乘客使用时，无论是坐姿状态还是 躺卧状态， 都可形成立体防护区域的一体化汽车座椅。
在汽车座椅背 4的中间位置处还设置有多功能安全装置 103， 该多功能安全 装置 103包括安全绳带 104; 所述安全绳带 104包括与汽车座椅背 4相连接的连 接端 1041， 还包括有自由端 1042， 所述自由端 1042安装有第三卡扣 12; 在乘 客坐姿状态下时， 该第三卡扣 12与安装于坐垫 5和座椅背 4连接处的第三卡扣 槽 13相配合卡合，在乘客躺卧状态下时，该第三卡扣 12与安装于坐垫 5底部的 第四卡扣槽 14 (如图 8所示）相配合卡合， 第四卡扣槽 14还连接有第二伸缩带 1401 , 第二伸缩带 1401固装在坐垫 5下方的座椅支撑座架 8上； 所述座椅支撑 座架 8上还设有可内置隐藏第四卡扣槽 14的第三隐藏口 15; 还可以的， 第四卡 扣槽 14还连接有第二伸缩带 1401， 坐垫 5下方具有座椅支撑座架 8， 所述座椅 支撑座架 8上还设有可内置隐藏第四卡扣槽 14的第四隐藏口 16 (如图 9所示）， 第二伸缩带 1401的连接端 1402固装在第四隐藏口 16内。
作为一种变化， 可将第二伸缩带 1401固装在坐垫 4的底部或更下面， 第三 隐藏口 15 (如图 10所示）也设置于坐垫 4的底部或更下面， 这样会更好的隐藏 第四卡扣槽 14。
如图 2所示， 安全绳带 104的连接端 1041连接在汽车座椅背 4的上端位置 A处或连接在坐垫 5和座椅背 4连接处之间的位置 B处。
采用本发明技术方案的多功能安全装置以及将该多功能安全装置安装于汽 车座椅上， 其产生的有益效果是： 对抗急停等状态的减速度， 使得躺卧的乘客或 物品不致与前排座椅发生撞击或翻滚落地； 分散了惯性力； 通过安全带的延伸， 再度缓冲惯性力的作用； 防止躺卧或物品抛出车外； 立体防护区域的形成， 防护 更全面， 阻挡包围作用更明显， 安全带还能起到扶手作用。
上面结合附图对本发明的实施方式作了详细的说明，但是本发明不限于上述 实施方式，在所属技术领域普通技术人员所具备的知 ώ范围内，还可以在不脱离 本发明宗旨的前提下做出各种变化。例如，可将本发明的多功能安全装置用于房 车中的坐卧一体化座椅； 还可以的， 如图 11所示， 在安全带 1上套装有一个卡 扣槽 17， 这样， 在不使用多动能安全带的或在不使用该卡扣槽 17的情况下， 卡 扣槽 Π滑落至靠近安全带 1下端处于不被明显发现或隐藏状态，当需要使用时， 尤其是汽车座椅的左右两侧都设有多功能安全装置时，左侧多功能安全装置的安 全带上的卡扣槽 17可以与右侧多功能安全装置的安全带上的卡扣相配合卡合， 使得座椅形成立体防护区域，提高了其安全性，或使得放置在座椅上的较大体积 物品处于立体防护区域， 不易脱离坐垫， 当然， 也可以将右侧多功能安全装置的 安全带上的卡扣槽与左侧多功能安全装置的安全带上的卡扣相配合卡合，或者左 右两侧的多功能安全装置至少有一侧的安全带上套装有卡扣槽 17; 作为另外一 种变化， 还可以是这样的：位于或靠近坐垫底部左端的卡扣槽可与设置于座椅右 侧的多功能安全装置的安全带上的卡扣相配合卡合， 反之，位于或靠近坐垫底部 右端的卡扣槽可与设置于座椅左侧的多功能安全装置的安全带上的卡扣相配合 卡合， 这样， 乘客可以根据自身的体型和舒适度选择哪一个卡槽与卡扣相卡合， 扩大了卡扣的适配度， 同时也提高了乘客的舒适度； 还可以的， 本发明中的安全 带在拉伸长度达到一定临界点时，其限制为只能向卷收器方向收缩，不可再拉伸， 这时形成的立体防护区域更加稳固， 其作为扶手更加牢靠，该结构设置适用于前 述所有技术方案。
