具体实施方式
现在参照下面的描述并还参照附图,详细示出了说明性的方法。虽然附图代表一些可行的方法,但是附图实质上是示意性的,因此附图没有按照比例绘制,一些特征被夸大或被去除以更好地示出和解释本公开。另外,在此所阐述的描述不意图是彻底的,或者将权利要求另外地限制或限定为在附图中示出和在下面的详细描述中公开的精确的形式和构造。
示例性车辆乘员约束***可包括单个气体发生器,该气体发生器用于向侧气囊充气以缓和前座乘员的冲击并用于向后气囊充气以缓和后座乘员的冲击。在一个示例中,侧气囊和后气囊可以是一个组合的气囊的一体化的部分,并且气体发生器可具有连接到侧气囊和后气囊的单个室。气体发生器可被构造为在碰撞事件期间分别使用第一气囊和第二气囊缓和第一乘员和第二乘员的冲击。作为一个示例,气体发生器可与侧气囊连通,从而气体发生器可向侧气囊充气,进而侧气囊将气体引导到后气囊以向后气囊充气。作为另一示例,气体发生器可具有向侧气囊和后气囊中的相应的一个充气的两个室。后气囊、侧气囊、气体发生器或者这三者之间的任何组合中的一部分或更多部分可以可滑动地附着到车辆座椅,以允许车辆座椅的座椅靠背在直立位置和倾斜位置之间运动,同时将所述***牢固地附着到车辆座椅。
参照图1,示例性的车辆乘员约束***100(“***”)可包括一个或更多个正面碰撞传感器102,正面碰撞传感器102响应于检测到正面的车辆碰撞而产生碰撞信号。作为一个示例,加速计是MEMS加速计,MEMS加速计是小的集成电路,该小的集成电路具有响应于快速减速而运动的集成的微型机械元件。该运动引起通过芯片上的电子器件检测的电容的变化,然后响应于电容的变化而产生碰撞信号。然而,所述***可具有响应于检测到车辆碰撞而产生碰撞信号的任何合适的碰撞传感器。
然后,所述***100还可包括控制器104,该控制器104接收来自所述传感器102的碰撞信号并基于该碰撞信号产生致动信号。此外,***100可具有一个单个气体发生器106,该单个气体发生器106接收来自控制器104的致动信号并基于该致动信号向侧气囊108和后气囊110充气。在该示例中,气体发生器106(图2)包括与连接到侧气囊和后气囊的两个歧管114a、114b中的各个连通的两个室112a、112b。然而,另一示例性的气体发生器306(图3)可改为包括与连接到侧气囊的歧管314连通的单个室312,进而侧气囊与后气囊连通。
返回参照图1,示例性的侧气囊108附着到车辆座椅122的侧部118a、118b。具体地讲,侧气囊108可具有胸部气囊116,该胸部气囊116锚接到车辆座椅122的座椅靠背120的侧部并与歧管114b(图2)连通,以接收从气体发生器106的室112b排出的气体。侧气囊108还可包括盆腔气囊124,盆腔气囊124附着到车辆座椅122的座椅底部126的外侧部118b并与胸部气囊116连通,以接收来自胸部气囊116的气体。在另一示例中,盆腔气囊可直接与气体发生器连通,进而盆腔气囊可与胸部气囊连通,使得气体发生器首先向盆腔气囊充气,进而盆腔气囊向胸部气囊充气。
示例性的后气囊110的至少一部分可附着到所述座椅122的座椅靠背120的后侧部118a(并可与歧管114a(图2)连通,以接收来自室112a的气体。此外,该形式的后气囊110可通过座椅靠背120的上部120a支撑并可与座椅靠背的中部分开,从而被充气的后气囊110能够缓和后座乘员的头部的冲击以减小头部伤害和颈部伤害,而不与(例如)位于后座中的儿童座椅发生干涉。单个气体发生器106可响应于致动信号向后气囊110充气,并且还可通过连续的填充管连接器125向胸部气囊116和盆腔气囊124充气,以缓和前座乘员和后座乘员的冲击。
参照图4,另一示例性的***400可具有侧气囊408、后气囊410和气体发生器406,并且大体上类似于图1的***100,***400具有由类似的但是以400系列的标号指示的相应的部件,例如,碰撞传感器402、控制器404、车辆座椅422的侧部418a、418b、座椅底部426和座椅靠背420。然而,与图1的具有与歧管114a、114b中的各个连通的两个室112a、112b的气体发生器106相比,***400可包括具有与单个歧管连通的单个室的单个气体发生器406。为此,所述气体发生器可大体上类似于图3中示出的气体发生器306。气体发生器406可在单个室中产生气体并将气体通过歧管引导到侧气囊408中,进而侧气囊408经由填充管连接器425与后气囊410连通,以向后气囊410充气。
如由图2最好地示出的,当气囊处于非展开的状态时,歧管114a和后气囊110可被容纳在填充管带128内。当然,另一歧管和侧气囊可设置在填充管带128内。此外,填充管带128可具有一个或更多个裂缝缝合线130,以在气囊处于展开的状态时允许气囊通过被打开的裂缝缝合线而膨胀并从车辆座椅122伸出。示例性的填充管带128和其中的歧管114b可固定到气体发生器106。然而,各种适合的紧固件可用于将填充管带和歧管附着到气体发生器。返回参照图1,***100可包括将填充管带128附着到车辆座椅122的多条系绳132。
侧气囊、后气囊、气体发生器或这三者的任何组合可滑动地附着到车辆座椅,使得枢转地附着到座椅底部126的座椅靠背120可在直立位置和倾斜位置之间运动。在该示例中,如图5中大体示出的,后气囊110的外侧部可滑动地附着到座椅靠背120的车辆框架134。具体地讲,***100可具有可滑动地装载在形成在车辆框架134中的槽136内的可调节的系绳132a。为此,所述系绳132a可朝向座椅底部126向下运动,以允许座椅靠背运动到倾斜位置。此外,***100可包括偏置构件138(例如,弹簧),偏置构件138使所述系绳132a远离座椅底部126向上运动,以使所述系绳132a在座椅靠背处于直立位置时向上运动,从而将后气囊110设置在期望的位置,以缓和后座乘员的头部的冲击而不与儿童座椅干涉。
参照图6,示出了操作图1的***100的示例性的方法600。在步骤602处,将后气囊110可滑动地附着到座椅靠背120,以允许座椅靠背120在倾斜位置和直立位置之间运动。具体地讲,当车辆座椅122运动到倾斜位置时,后气囊110的外侧部朝向座椅底部126运动,并且当所述座椅122运动到直立位置时,后气囊110的外侧部朝向车辆座椅122的上端120a运动。偏置构件可将后气囊附着到座椅靠背120,以使后气囊110朝向座椅靠背120的上端120a运动。然而,侧气囊、气体发生器和后气囊的任何组合都可以可滑动地附着到车辆座椅的各个部分。
在步骤604处,一个或更多个传感器102响应于检测到的车辆碰撞而产生碰撞信号。在该示例中,传感器可以是MEMS的。然而,传感器可以是其它合适的传感器。
在步骤606处,控制器104响应于至少从所述传感器102接收到的碰撞信号而产生致动信号。致动信号可基于多个碰撞信号与任何合适的计算机算法的结合使气囊展开。
在步骤608处,气体发生器106响应于从控制器104接收的致动信号而向侧气囊108和后气囊110充气。该步骤可通过将气体直接从单个气体发生器106的一个室112a排放到后气囊110并将气体直接从另一个室112b排放到侧气囊来实现。然而,该步骤可通过如下步骤代替实现:经由各个填充管连接器125通过侧气囊108将气体从单个气体发生器106排放并进入到后气囊110中。
对于在此描述的程序、***、方法和启发等,应该理解的是,虽然这样的程序等的步骤已被描述为根据某一有序的顺序进行,但是这样的程序等可按照除了描述于此的顺序以外的顺序执行的被描述的步骤来实践。还应该理解的是,可同时执行某些步骤,可增加其它步骤,或可省略描述于此的某些步骤。换句话说,在此提供程序的描述是为了说明某些实施例的目的,并且决不应该解释为限制要求的本发明。
因此,应该理解的是,上面的描述意图是说明性的并不是限制性的。在阅读上面的描述时,除了提供的示例之外的许多实施例和应用将是显而易见的。本发明的范围不应该参考上面的描述来确定,而是应该参照所附的权利要求以及这样的权利要求被赋予其的等同物的全部范围来确定。可预见和预期的是,未来的发展将出现于在此所讨论的技术中,并且所公开的***和方法将被合并到这样的未来的实施例中。总之,应该理解的是,本发明能够进行修改和变型。
除非明确指出与在此描述的意思相反,否则权利要求中所使用的所有术语意图在于给出如熟知在此描述的技术的技术人员所理解的普通含义和最宽的合理的解释。具体地讲,除非权利要求进行了清楚的相反的限制,否则单数的使用应该被理解为描述所指示的元件中的一个或更多个。
