Description
相关申请的交叉引用
本申请要求享有2011年5月20日申请的、名称为“具有弹性枢轴的运动座椅”、序列号为61/488326的美国临时申请的权益,其全部内容通过引用合并在此。
技术领域
本发明的实施例大体上涉及一种用于运动座椅靠背的改进的枢轴连接。
背景技术
许多座椅设计为允许乘客从完全竖直落座的位置移动到部分或完全后靠的位置。这些座椅可能仅允许少量的向后动作,或者它们可能是可以后靠到很大程度的座椅。作为示例,飞机以及其它乘客运输交通工具,例如火车或大巴,通常具有可以后靠的座椅或者具有带某种“弹力”动作的靠背。这使得乘客舒适,因为车辆的移动可能是强烈或颠簸的,并且舒适的座椅优选的是具有带至少一些弹性的靠背部分。用于车辆的优质座椅还可以具有可调节的椅盘,这样就允许椅盘的向前和向后移动,同时还允许靠背的后靠动作。电影院、礼堂、运动场、家里和/或办公室使用的座椅也能从具有铰接的或“反弹作用”的靠背部分获益,因为在一段时间内完全坐直而没有任何“弹力”或弹性回弹是不舒服的。
运动座椅靠背的枢轴连接部位,如果提供的话,通常由传统的枢轴部位来提供,包括销和突耳。这些传统的枢轴具有一些问题,其防止了某些运动座椅所要求的用途。例如,销和突耳的组合具有的重量大于某些用途所要求的重量,部件的成本高于所要求的,在使用中它们会产生噪声,它们经受因摩擦带来的磨损和开裂,并且它们还进一步经受松动。因此,需要提供一种用于运动座椅的改进的弹性部位。
发明内容
这里描述的本发明的实施例由此提供一种用于运动座椅靠背的改进的枢轴连接。某些实施例提供一种弹性枢轴,其形成为屈曲交织部,连接座椅靠背的上部部分和下部部分。屈曲交织部可以是弯曲结构或者具有弯折尺寸的内支腿和外支腿。例如,可提供一种运动座椅,包括:座椅框架、椅盘、座椅靠背;以及位于椅盘侧边的侧梁支撑,所述侧梁支撑提供通过至少两个屈曲交织部形成的弹性枢轴。
每个屈曲交织部都可包括支腿,其具有第一端部和第二端部,第一端部从侧梁支撑延伸,第二端部固定到座椅靠背。屈曲交织部可由延伸自单个分支部位的两个支腿形成,每个支腿具有将每个支腿分为上端部和下端部的弯折。两个屈曲交织部可每个都具有使得座椅靠背可以移动的弯曲度。使用中,屈曲交织部大体上彼此交叉,来形成“X”结构。座椅靠背可包括上部部分和下部部分,其中靠背绕着弹性枢轴转动。。

具体实施方式
虽然这里描述的座椅的具体用途是飞机座椅和其它乘客运输车辆,但是该座椅和部件可用于任何向后靠和/或枢转的座椅,包括家居和/或商业的使用。这些座椅枢轴可用于飞机座椅的一个理由是飞机上非常关注重量、成本和耐久性,由此,改进的座椅枢轴方案发现在飞机环境中是特别合适且理想的。尽管说明书的其它部分集中于所描述的座椅在飞机和其它乘客运输车辆上的使用,但是可以理解的是,描述的这些座椅和部件可使用在任何场所,例如音乐厅、运动场、礼堂、电影院、学校、家里和办公室座椅,等等。该概念可用于单独的/独立的座椅,也可以用于彼此串连的座椅。此外,尽管描述为用于座椅,但是,这里描述的弹性枢轴也可以用于其它的机械装置,这些机械装置获益于不用销和突耳的枢转动作。
图1示出了一排座椅10。示出的座椅是运动座椅10,具有位于靠背14上的弹性枢轴12。具体地说,靠背14提供有上部部分16和下部部分18。在示出的例子中,上部部分16和下部部分18被中间部分20分开,但中间部分20不是必须的。座椅还具有椅盘22,如图4所示。椅盘22(图1未示出,以便示出下部座椅框架24)通常提供作为与靠背14分开的部件,尽管,如果需要的话,可以想到所有座椅部件可以提供为单个一体件。然而,椅盘22典型地可独立于靠背14移动。椅盘安装在下部座椅框架24上。下部框架24一些部件的移动允许/致使椅盘22的移动。
侧梁支撑26沿着椅盘22的两侧且大体上连接下部框架24。侧梁支撑26一般由刚性的材料制成,这些材料如果有的话,也具有非常小的弹性或“弹力”。每个侧梁支撑26的上部区域28提供形成弹性枢轴12的部件。可能的是多于一个的部件连接或相互协作来形成侧梁支撑26。例如,图8示出了侧梁支撑26的第一部分A和侧梁支撑26的第二部分B,其一起协作形成侧梁支撑26,并执行下面描述的功能。还可能的是,提供多于两个部件一起形成每个侧梁支撑26。侧梁支撑26总的来说使弹性枢轴的部件间接地连接到座椅框架24。
在示出的例子中,弹性枢轴12通过至少两个交叉的屈曲交织部30形成,如图2所示。(尽管图中示出的是两个屈曲交织部及其部件,可以理解的是,可使用多于两个的屈曲交织部,以提供更大的张力,或者提供更小但是更多数量的支腿)。如图6所示,侧梁支撑26的上部区域28分支形成内支腿32和外支腿34。内、外支腿32、34在分支部位36形成类似Y形的结构。分支部位36提供了每个支腿32、34的第一端部38、40。内支腿32具有弯折42,形成了内支腿32的上部部分44。内支腿32在上部部分44的端部具有第二端部46,第二端部46固定到靠背14的连接部分48,如图1所示。内支腿32大体上固定到连接部分48的内部区域58。
外支腿34具有相似的弯折52,形成外支腿34的上部部分54。外支腿34在上部部分54的端部具有第二端部56,其也固定到靠背14的连接部分48(外支腿32大体上固定到连接部分48的外部区域50)。侧梁26的Y形分支部位36与第二端部46、56连接至靠背14的连接部分48相结合提供了弹性枢轴12。在这个实施例中,内支腿和外支腿32、34在竖直平面上彼此交叉,当从侧面看时,形成“X”,如图2和3所示。
完全有可能形成具有更大弯曲度的支腿,使得它们在水平面上也交叉。换句话说,内支腿32可连接到外部区域50,外支腿34可连接到内部区域58。如果间隔不合理,将产生摩擦,但是这是屈曲交织部30可以采取的一种潜在形式。
在另一个实施例中,屈曲交织部30由不具有弯折,而是在不使用时保持大体是直的且一旦施加张力时轻微弯曲的支腿32、34形成。这样的支腿大体上比具有弯折的支腿更加结实或者更厚或者设计得具有更大的刚度,因为直的支腿没有那么多的后伸。在这个实施例中,后伸的特征通过材料自身提供。图7提供为阐明弹性枢轴的任何上部形状都是可能的。图8示出了支腿32、34可以是弯曲的,不具有特定的弯折部位。该特征也示出在图3中。
通常,弹性枢转部位12的动作类似钓鱼竿-它可以弯曲,但是一旦压力释放,很快恢复到原始结构。然而,由两个支腿或部分形成的屈曲交织部30带来的效果之一是只有一个支腿可以弯曲且变形,但是没有平衡的“反弹”支腿。通过提供两个弹性肋条/支腿,连接部位处的相对肋条提供了相反的力。
使用中,随着椅盘22向前移动,靠背14可以后靠。在这个移动中,靠背14绕着弹性枢轴12枢转,部分是由于靠背14的下部部分18和椅盘22通过侧梁支撑26的固定。随着靠背的上部部分16(枢轴轴线上方的部分)向后移动,下部部分18在座椅10向后靠时向前移动。通常,为了限制靠背进入每个座椅10后面乘客的空间,枢转部位尽可能高地移动。(尽管图中示出了靠背上枢转部位的一个位置,但可以理解的是,弹性转轴能够位于要求的靠背上任何位置。)基于弹性枢转部位12沿着靠背14定位的位置,靠背上部部分的倾斜量可以改动。通常,当完全直立时,在滑行、起飞和降落位置,飞机座椅提供与竖直位置成15°的座椅。当后靠时,飞机座椅通常从竖直后靠至30°。(这些范围用于乘客舱的飞机座椅;用于海外航班的优质座椅可向后靠到睡眠位置,显然在这些范围之外,后靠至更大的程度。)
由于靠背14连接到椅盘22(直接的或间接的),所以,当椅盘22向前移动并且锁定到位时,允许靠背14后靠。靠背的下部部分18也可以连接到底部椅盘22,从而当乘客向后靠靠背时,底部椅盘22向前移动。为了控制靠背14和底部椅盘22的动作,并且如果底部椅盘22和靠背14连接到一起,那么连接到椅盘22的装置60用来锁定位置,从而靠背14的后靠也被控制了。
例如,图5示出了部件60,其固定到座椅框架24的杆62、64上。一旦椅盘22处于所需的位置,座椅乘客可以将部件60锁定到位,帮助控制靠背14的后靠动作。
在不脱离本发明以及所附权利要求的范围或精神下,可以对上述陈述以及图中示出的结构和方法进行改动、修改、增加以及删除。
