一种侧部车柱气帘导向装置包括具有斜面接收部和连接到斜面接收部的气帘斜面***件的主体。主体由具有强度S1和延展性D1的第一材料制成,同时气帘斜面***件由具有强度S2和延展性D2的第二材料制成,其中S1>S2且D1<D2。
Description
技术领域
本发明总体上涉及用于保护侧面碰撞中车辆乘员的气帘***,并且更具体地,涉及一种包含用于引导气帘越过车辆中心或B-车柱总成的斜面的侧部车柱气帘导向装置。
背景技术
本领域所公知的是气帘保护车辆乘员免受侧面碰撞。这样的***通常包括气帘导向装置,该气帘导向装置包含斜面以引导对气帘充气的轨道以便充气气帘在展开期间不会接触中心饰件或B-车柱饰件的上边缘。此设置的目的在于最小化车柱饰件变为分离且防止气帘达到其预期的“展开”位置的任何可能性,气帘可以从该位置提供最大的安全性好处。
侧部车柱气帘导向装置当由迅速使气帘充气而接触时为了提供所需斜面功能通常是完全刚性。与以抵挡初始碰撞和引导充气的气帘的必要强度相比,气帘导向装置同样必须包含在头部碰撞情况下的能量吸收措施以便最小化对车辆乘员的潜在伤害。在过去,这些措施通常占据车顶内衬后面的空间,驱使车顶内衬表面进入客舱内部,由此损害了车辆内部宽敞性。
本发明涉及一种侧部车柱气帘导向装置,该侧部车柱气帘导向装置提供用于恰当引导对气帘迅速充气的必需强度,同时也提供在头部碰撞的情况下最小化头部伤害所必需的所需能量吸收特性。而且这是由紧凑结构实现的,该紧凑结构允许车辆乘客舱内部空间最大化的可能性。
发明内容
根据本文所描述的目的和有益效果,提供一种侧部车柱气帘导向装置。导向装置包括主体,该主体包括斜面接收部和连接到斜面接收部的气帘斜面***件。主体由具有强度S1和延展性D1的第一材料制成。相反地,气帘斜面***件由具有强度S2和延展性D2的第二材料制成,其中S1>S2且D1<D2。
在一个可能的实施例中,主体包括斜面挡板(ramp apron),以及接收部邻近斜面挡板且在斜面挡板下方。斜面挡板具有第一气帘导向表面且气帘斜面***件具有与第一气帘导向表面对齐的第二气帘导向表面。气帘斜面***件符合用于头部碰撞的FMVSS201规程。
在一个可能的实施例中,气帘斜面***件包括从主体以与主体呈锐角夹角伸出的多个肋。该锐角夹角可以是10度和60度之间。或者,该锐角夹角可以是30度和40度之间。
在另一个可能的实施例中,气帘斜面***件包括蜂巢状阵列。该阵列可以具有4-7个蜂巢单元或120-130mm的X轴或前部-后部维度以及1-2个蜂巢单元或20-25mm的Y轴或横向车辆维度。蜂巢状阵列同样可以具有1.5-2.5mm的z轴维度或厚度。X维平行于斜面接收部的一个面且Y维垂直于斜面接收部的上述面。每个蜂巢单元可以具有六面且每面的长度可以是6mm。
在另一个可能的实施例中,气帘斜面***件包括多个蜂巢状阵列,其中蜂巢状阵列由间隙分开以确保气帘斜面***件较大的可变形性。
在一个可能的实施例中,斜面接收部包括凹部。在一个可能的实施例中,第二材料是闭孔泡沫橡胶。在另一个可能的实施例中,第二材料是高性能闭孔泡沫塑料。
根据另一方面,提供一种包含主体的侧部车柱气帘导向装置,该主体包括斜面接收部和连接到主体的气帘斜面***件。该气帘斜面***件具有蜂巢状结构。
当侧部车柱气帘导向装置***件处于连接到主体的操作位置时,该蜂巢状结构的蜂巢单元在竖直面对齐。而且,蜂巢单元与斜面接收部的一个面平行对齐。
在下面的说明书中,存在示出的和描述的多个侧部车柱气帘导向装置的实施例。应当认识到,侧部车柱气帘导向装置能够具有其它不同的实施例,并且其若干细节能够在各种明显的方面修改,所有修改不脱离在如前所述和以下权利要求中说明的导向装置。因此,附图和说明书应该理解为实际上说明性的并非限制性的。

现在将详细地参考导向装置的目前的优选实施例,导向装置的示例如附图中所示。
具体实施方式
现参考图1-3,示出了侧部车柱气帘导向装置10的第一实施例。导向装置10包括包含以侧面凹部形式的斜面接收部14的主体12。气帘斜面***件15被接收进主体12上的斜面接收部14中且保持在主体12上的斜面接收部14中。气帘斜面***件15包括从安装基座17伸出的多个肋16。显著地,肋16从基座17和装配的导向装置10的主体12以锐角夹角伸出以便肋16具有提高的可变形性的特征,提高的可变形性在与车辆乘员头部碰撞的情况下提供理想能量吸收特征。
在一个可能的实施例中,锐角夹角在10度和60度之间。在另一个可能的实施例中,锐角夹角在30度和40度之间。在另一个可能的实施例中,锐角夹角大约为30度。
如进一步说明的,主体12包括斜面挡板18。斜面接收部14邻近且正好在斜面挡板18下方。斜面挡板18包括第一气帘导向面20且气帘斜面***件15包括由肋16上边缘形成的第二气帘导向面22。当气帘斜面***件15恰当地固定在斜面接收部14中且由超声波焊接或其它合适方式连接到主体12时,两个面20、22是对齐的。
显著地,主体12由具有强度S1和延展性D1的第一材料制成。相反地,气帘斜面***件15由具有强度S2和延展性D2的第二材料制成,其中S1>S2且D1<D2。在一个可能的实施例中,主体12由聚碳酸酯-丙烯腈·丁二烯·苯乙烯(polycarbonate-acrylonitrilebutadiene styrene,PC-ABS)制成且气帘斜面***件15由聚丙烯制成。在另一个实施例中,气帘斜面***件由25%应变下具有在60kPa和200kPa之间的抗压强度的闭孔泡沫橡胶制成。在另一个可能的实施例中,气帘斜面***件由25%应变下具有在90kPa和200kPa之间的抗压强度的闭孔泡沫塑料制成。
当然,可以理解的是可以使用其它材料。在一个特别有益的实施例中,制造主体12的第一材料具有大约40MPa到大约60MPa之间的强度S1和在S1规定范围内的材料固有的延展性D1,第一材料适用于汽车应用。相比之下,制造气帘斜面***件15的第二材料具有大约60MPa到大约200MPa之间的强度S2和通常大于D1的延展性D2。由于内部头部碰撞要求不仅是可靠的斜面***件15刚度而且是由***的头和车辆内部部件之间的相互作用产生的可靠的动力学,所以限定在此处必须满足的气帘斜面***件的主要机械参数是基于在准静态压溃测试下在0.60到0.75mm/mm的压缩应变的情况下从0.25MPa到0.80Mpa的抗压应力的能量吸收。
现参考图4-12,示出了侧部车柱气帘导向装置10′的第二实施例,侧部车柱气帘导向装置10′包括:(a)具有斜面接收部14′和斜面挡板18′的主体12′,以及(b)蜂巢状结构的气帘斜面***件15′。显著地,蜂巢状的气帘斜面***件15′在与车辆乘员的头部碰撞的情况下提供理想的能量吸收特征。如上先前的实施例所述,气帘斜面***件15′嵌入到斜面接收部14′中且用超声波焊接或其它方式固定到主体12′。当恰当固定时,斜面挡板18′的第一气帘导向面20′与由气帘斜面***件15′的蜂巢单元24′形成的第二气帘导向面22′对齐。
气帘斜面***件15′的蜂巢状阵列具有在约120-130mm的长度上4-7个蜂巢单元24′之间的X轴维度(平行于斜面接收部14′的面26′且在机动车辆前部-后部方向上延伸)和约为20-25mm的在长度上1-2个蜂巢单元的Y轴维度(垂直于面26′且在机动车辆横向上延伸)。蜂巢状阵列可以具有大约1.5-2.5mm之间的高度或z轴维度。当侧部车柱气帘斜面***件15′处于连接到主体12′的操作位置时,蜂巢状阵列的蜂巢单元24′与竖直面(z轴方向)对齐。蜂巢状阵列的每个蜂巢单元24′可以具有六个面28′且每一面长度可以是例如6mm。
现参考图10-12,示出了导向装置10′上侧气帘C的展开。如所示,导向装置10′安装到前和后车门之间的车辆中心侧部车柱P(B-车柱)以便压在车柱饰件T上。未展开的侧气帘C设置为上覆盖导向装置10′且侧气帘C和导向装置10′都由车顶内衬H隐藏。如图11中所示,在侧面碰撞的情况下,侧气帘C被展开。随着侧气帘C迅速充气,侧气帘C接合包括斜面挡板18′的第一气帘导向面20′和由侧车柱气帘斜面***件15′顶部边缘形成的第二气帘导向面22′的导向装置10′且由导向装置10′引导。可以理解的是,斜面***件15′当由充气的侧气帘C沿着顶部边缘的倾斜部分接合时强有力地抵抗任何偏差。因此,充气的气帘C由导向装置10′引导到车柱饰件T的上方施加压力到车柱饰件T和车顶内衬H之间的间隙,气帘通过间隙展开进其为了最大化车辆乘员利益的功能和所需位置。当斜面***件15′强有力地抵抗在竖直方向上的偏差(参见图12且注意动作箭头A)以便恰当地将充气的气帘C引导在车柱饰件T上时,斜面***件的蜂巢单元24′在水平方向上是完全可变形(同样注意动作箭头B)以便缓冲可能发生在其他时间的任何头部碰撞。
现参考图13和14,示出了包括侧部车柱气帘导向装置10″的斜面***件15″的另一可替换实施例。导向装置10″包括具有斜面接收部14″和保持在接收部中的多个蜂巢状阵列19″的主体12″。与图4-12示出的导向装置10′的第二实施例相比,导向装置10″的第三实施例包括四个蜂巢状阵列19″,四个蜂巢状阵列19″相互不接合。在一个可能的实施例中,四个蜂巢状阵列19″由具有6.0-7.0mm宽度的间隙G相互间隔开。该间隔在蜂巢状阵列19″之间确保在水平方向(Y轴)上更大的可变形性以便斜面***件15″可以在车辆乘员的头部碰撞的情况下吸收更多能量。
总之,使用侧部车柱气帘导向装置10、10′、10″的示出实施例产生众多有益效果。显著地,全部三个实施例10、10′、10″包含由第一材料制成的主体12、12′、12″,第一材料具有为了将导向装置安装到B-车柱调整以提供所需性能的强度S1和延展性D1。此外全部三个实施例10、10′、10″包含斜面***件15、15′、15″,其由调整以提供所需性能的第二材料制成,所需性能包括在竖直方向上必要的刚度以接收和引导车柱饰件T上迅速充气的气帘C以便气帘被接收进它的能够保护车辆乘员免受侧面碰撞的所需展开位置。同时,斜面***件15、15′、15″在水平方向上提供显著的可变形性以便斜面***件15、15′、15″可以吸收在车辆乘员的头部碰撞情况下的能量。有利地,针对主体12、12′、12″和斜面***件15、15′、15″使用两种不同材料大体上消除了性能折中且形成一更好性能的产品。蜂巢状结构包含到斜面***件15′、15″中同样允许为了满足包括FMVSS201规程的设计目标的性能调节。
为了说明和描述的目的已经提出前述内容。这样不是为了详尽描述或限制实施例到所公开的准确形式。对依据上述教导的明显修改及改变是可能的。当按照权利要求公平,合法和公平享有的宽度解释时,所有这些修改和改变均包括在所附权利要求的范围内。
