Description
技术领域
本公开涉及一种用于车辆的安全气囊装置,并且更具体地,涉及一种用于车辆的通过在车辆发生碰撞时充气和展开来限制并保护乘客的安全气囊装置。
背景技术
一般来讲,车辆安全气囊装置是用于在车辆发生碰撞时通过根据碰撞检测传感器的信号将气体注入安全气囊中并且使安全气囊快速充气来保护乘客的安全装置。
此类安全气囊装置安装在设置在车辆中的方向盘、仪表盘、座椅、侧壁等中,并且在车辆发生碰撞时通过朝向乘客的前侧或侧面充气来保护乘客。
即,车辆可设置有在驾驶员座椅和乘客座椅前方展开的正面安全气囊、从乘客侧面展开以保护乘客的帘式安全气囊和侧面安全气囊,以及用于保护乘客膝盖的膝部安全气囊,等等。
最近,正在开发自动移动而无需驾驶员驾驶的自主车辆。
自主车辆通过使用用于识别车辆周围事物的高技术传感器和高性能图形处理设备来检测设置在车辆中的每个设备的状况和车辆周围的状况,并且在根据检测结果控制设置在车辆中的每个设备的操作的同时行进。
高技术传感器可测量事物如人类之间的距离,并且可检测危险并且帮助车辆查看所有区域而不存在盲区。此外,图形处理设备可以通过若干相机捕获车辆的周围环境,并且可以分析其图像并且帮助车辆安全行进。
例如,自主车辆可具有安装在其中的LiDAR设备、声波设备、3D相机、雷达设备,等等。
由于如上所述配置的自主车辆不需要驾驶员驾驶,因此包括驾驶员座椅在内的所有座椅都可以自由旋转,并且可以通过倾斜操作将靠背的角度调节为水平。
乘客可以各种方式调节靠背的角度,并且可以旋转座椅并且可以在后座上进行面向乘客的会议。
因此,不可能应用参考坐在面向自主车辆前方的座椅上的乘客的姿势设计的普通安全气囊装置。
下面呈现的专利文档1和专利文档2公开了用于车辆的乘客保护系统配置。
由于乘坐在自主车辆中的乘客不直接驾驶,因此在前往目的地时,乘客可通过在水平方向上旋转座椅来参加会议,或者可通过向后倾斜靠背来休息。
由于在自主车辆中座椅和靠背可以朝前和朝后以及在水平方向上自由旋转,因此乘客的方向和姿势可以不同地改变。
因此,需要安全地保护乘客而不管车辆发生碰撞时乘客的方向和姿势如何的安全气囊技术。

发明内容
技术问题
本公开的目的是解决上述问题,并且提供用于车辆的通过在车辆发生碰撞时朝向乘客两侧充气和展开来保护乘客的安全气囊装置。
本公开的另一个目的是提供用于车辆的可通过从座椅的两侧充气和展开多对安全气囊缓冲垫来安全地保护乘客的安全气囊装置。
问题的解决方案
为了实现上述目的,根据本公开的用于车辆的安全气囊装置可包括:安全气囊垫,该安全气囊垫在车辆发生碰撞时充气并从乘客两侧沿向前方向展开以保护乘客两侧;和充气机,该充气机被构造成通过冲击检测信号生成气体并将气体供应到安全气囊垫,并且安全气囊垫可包括第一安全气囊,该第一安全气囊被构造成保护从乘客肩部到乘客下部身体部位的两侧或一侧;和第二安全气囊,该第二安全气囊被构造成保护乘客头部和乘客肩部的两侧。
本发明的有利效果
根据如上所述的根据本公开的用于车辆的安全气囊装置,存在以下效果:第一安全气囊和第二安全气囊在车辆发生碰撞时充气并朝向乘客两侧展开,并且限制和保护乘客的上部身体和下部身体。
即,根据本公开,第一安全气囊安装在车辆座椅的靠背中,并且第二安全气囊安装在头枕中,使得乘客身体和头部可在车辆发生碰撞时受到限制。
具体地讲,根据本公开,第二安全气囊被设置成与第一安全气囊的上端重叠,使得可有效防止或限制车辆发生侧向碰撞所引起的乘客的移动。
因此,存在以下效果:在自主车辆中在座椅和靠背沿各种方向和角度旋转的状态下,可以有效地限制和安全地保护乘客。
附图说明

图2和图3分别是用于图1所示车辆的安全气囊装置的前视图和平面图;
图4是根据本公开的另一实施方案的用于车辆的安全气囊装置的透视图;
图5是图4所示的用于车辆的安全气囊装置的前视图;并且
图6是根据本公开的又一实施方案的用于车辆的安全气囊装置的透视图。
实施本发明的最佳方式
在下文中,将参考附图详细描述根据本公开的优选实施方案的用于车辆的气囊装置。
本公开通过以下方式安全地保护乘客:通过相对于乘客的两个肩部以及下部身体部位(包括乘客骨盆和髋部)的两侧朝向包括乘客头部和胸部的上部身体的两侧充气并展开安全气囊缓冲垫来限制乘客上部身体和下部身体整个的移动。
具体地讲,本公开可通过在车辆发生碰撞时充气和展开安全气囊垫,以围绕乘客的前部与两侧来保护乘客的前部,并且可防止车辆中的飞行物体或破碎部件所引起的伤害。
此外,本公开可通过充气并从乘客骨盆和髋部的前下部分向上展开安全气囊垫来防止乘客在车辆发生正面碰撞时沿向前方向移动的下潜现象。
此外,本公开可以通过在后座上的乘客与靠背碰撞时进行缓冲,通过充气并从座椅靠背的后表面展开安全气囊缓冲垫来安全地保护后座上的乘客。
此外,将描述安装在一般车辆的驾驶员座椅中的安全气囊装置的构造,其中基于驾驶员的座椅面向车辆的前表面的方向被称为“向前方向(F)”,并且面向车辆的后表面的方向被称为“向后方向B”。与这些术语一起,指示方向诸如“左侧(L)”、“右侧(R)”、“向上方向(U)”和“向下方向(D)”的术语被定义为指示相对于上述沿向前方向和向后方向的相应方向。此外,在附图中示出的附图标号I表示车辆在车辆宽度方向上的向内方向,并且附图标号O表示车辆在车辆的宽度方向上的向外方向。
因此,车辆的前后(F、B)方向可表示为水平方向,并且车辆的上下(U、D)方向可表示为纵向方向。
图1是根据本公开的优选实施方案的用于车辆的安全气囊装置的透视图;并且图2和图3分别是用于图1所示车辆的安全气囊装置的前视图和平面图。
如图1至图3所述,根据本公开的优选实施方案的用于车辆的安全气囊装置10包括安全气囊垫20,该安全气囊垫在车辆发生碰撞时充气并从乘客两侧沿向前方向展开以保护乘客两侧;和充气机21,该充气机通过冲击检测信号生成气体并将气体供应到安全气囊垫20。
安全气囊垫20可以充气并从乘客的两侧沿向前方向展开,以对应于包括乘客头部和胸部、相对于乘客肩部的腹部以及包括乘客骨盆和髋部的下部身体部位。
为了实现这一点,安全气囊垫20可以包括一对第一安全气囊30,该一对第一安全气囊用于保护自乘客肩部的下部身体部位的两侧;和第二安全气囊40,该第二安全气囊用于保护乘客头部和乘客肩部的上端的两侧。
具体地讲,一对第一安全气囊30分别安装在乘客坐在其上的座椅11的靠背12中,并且充气并从靠背12的两侧沿向前方向以及向上和向下方向展开,以限制自乘客肩部的下部身体部位的两侧。
第一安全气囊30可以折叠状态容纳在车辆的靠背12中,并且可以作为侧部安全气囊提供,以限制和保护乘客的上部身体部位和下部身体部位的两侧。
第二安全气囊40安装在安装在靠背12的上端的头枕13中,并且从乘客头部的两侧沿向前方向以及沿向上和向下方向充气,以限制乘客头部以及乘客肩部的上端的两侧。
第二安全气囊40可以折叠状态容纳在头枕13中,并且可在车辆发生碰撞时从充气机供应气体,并且可通过在头枕13的后表面上形成的切割线充气并展开到头枕13的外部。
当在上文中观察时,第二安全气囊40可基本上以倒U形(“∩”)充气和展开。
即,当第二安全气囊40展开时,第二安全气囊40可充气和展开,使得第二安全气囊40的中心41设置在头枕13的后侧上,并且第二安全气囊40的两端42分别设置在乘客头部的两侧上。
在本文中,第二安全气囊40的两端42可设置得比一对第一安全气囊30的上端更靠内,以分别与一对第一安全气囊30的上端重叠。
因此,当第二安全气囊40的两端42朝向一侧移动时,它们可分别被一对第一安全气囊的上端卡住和支撑。
即,当乘客头部朝向一侧移动并且第二安全气囊由于车辆发生侧向碰撞而被推出时,第二安全气囊的端部支撑在第一安全气囊的上端上以有效地防止或限制乘客头部的移动。
虽然在本实施例中示出了第二安全气囊40的两端42设置得比一对第一安全气囊30的上端更靠内,但本公开并不限于此。
图4是根据本公开的另一实施方案的用于车辆的安全气囊装置的透视图;并且图5是图4所示的用于车辆的安全气囊装置的前视图。
如图4和图5,根据本公开的另一实施方案的用于车辆的安全气囊装置10与上文参考图1和图3所述的安全气囊装置10的构造相同,并且与其不同之处在于,第二安全气囊40的两端42设置得比一对第一安全气囊30的上端更靠外。
即,当在上文中观察时,第二安全气囊40可充气并基本上以倒置的方U形展开。
因此,当乘客的上部身体或下部身体由于车辆发生侧向碰撞而朝向一侧(例如向左侧)移动并且左侧的第一安全气囊30被推出时,对应的第一安全气囊30可支撑在第二安全气囊40的左端42上,以有效地防止或限制乘客的移动。
在本文中,一对拴系件43可安装在第二安全气囊40上以限制充气展开形状。
每个拴系件43的一端可连接到第二安全气囊40的前表面的中心,并且每个拴系件43的另一端可连接到第二安全气囊40的两端42。
当然,本公开不一定限于此,并且拴系件的数量、连接位置、长度等可根据第二安全气囊的尺寸、展开形状而不同地改变。
例如,可以提供多对拴系件43,或者一个拴系件43的两端可以分别连接到第二安全气囊40的两端42。
此外,拴系件43的两端可以分别连接到头枕13和第二安全气囊40的两端42。
此外,可以改变本公开以将拴系件施加到第一安全气囊,从而限制展开形状。
虽然在上述实施例中示出了第一安全气囊设置在靠背的两侧上,但本公开并不限于此。
例如,图6是根据本公开的又一实施方案的用于车辆的安全气囊装置的透视图。
如图6所示,根据本公开又一实施方案的用于车辆的安全气囊装置10与上文参考图1至图5所述的用于车辆的安全气囊装置10的构造相同,并且与之不同的是扶手14安装在靠背12的一侧上。
在本文中,扶手14可在乘客将他/她的手臂放置在其上时舒适地支撑乘客手臂,并且还可防止或限制乘客在车辆发生侧向碰撞时朝向碰撞的相对侧移动。
当扶手14安装在座椅11的一侧上,例如右侧上时,如上所述,可以移除安装在靠背12的右侧上的第一安全气囊30,并且可以将一个第一安全气囊30安装在靠背120的左侧上。
当然,本公开不限于此,并且当座椅11的一侧上设置有防止乘客侧向移动的支撑结构(如扶手14或控制台箱)时,可改变为仅将第一安全气囊30安装在靠背12的一侧上。
因此,第二安全气囊40的两端42中的仅一者可安装成与第一安全气囊30的上端接触。
通过上述方法,本公开可以通过在车辆发生碰撞时对乘客的两侧上的第一安全气囊和第二安全气囊充气和展开来限制和保护乘客的上部身体和下部身体。
即,本公开具有安装在车辆座椅靠背的第一安全气囊和安装在头枕中的第二安全气囊,从而在车辆发生碰撞时限制乘客身体和头部。
具体地讲,本公开具有第二安全气囊,该第二安全气囊设置成与第一安全气囊的上端重叠,从而有效地防止或限制车辆发生侧向碰撞所引起的乘客的移动。
因此,本公开可通过在自主车辆中在座椅和靠背以各种方向和角度旋转的状态下有效地限制乘客来安全地保护乘客。
虽然已经根据上述实施方案具体描述了由本申请的发明人制造的本发明,但是本公开不限于上述实施方案,并且可以在本公开的技术实质的范围内以各种方式进行修改。
