Description

便于坐入的座椅的滑轨组件
技术领域
本发明涉及一种机动车辆的座椅滑轨组件。
背景技术
机动车辆包括座椅组件,用于在车辆内支承坐着的乘客。座椅组件典型地包括一个座垫和一个座椅靠背,该座椅靠背由一个倾斜机构转动地连接到座垫上,以便能够在多个后仰位置间相对于座垫转动地调节座椅靠背。而且,座椅组件典型地包括一个滑轨组件,用于在车辆内在滑轨组件所限定的预定舒适乘坐位置范围内,比如最靠前和最靠后位置之间,纵向步进地滑动调节座椅组件。
众所周知,为便于进入车内座椅组件之后的空间,倾斜机构和滑轨组件被用于使座椅组件前倾至一个位于舒适范围之外或之前、比如在最靠前位置之前的前伸倾倒位置。另外,在本技术领域内所知晓的几种滑轨组件能使座椅组件从前伸倾倒位置返回到最靠前或最靠后位置。更复杂和昂贵的滑轨组件甚至能使座椅回到最初的乘坐位置。这类滑轨组件通常被认为是具有座椅滑轨的记忆功能,如同在美国专利5855413、5352019和5688023中所述的。
人们仍然希望有一种简单、经济且可靠的座椅滑轨组件,它能使座椅组件前倾并伸向一个位于舒适范围内的最靠前位置之外的前伸位置,并能使座椅组件返回到舒适范围内的预定的单点记忆位置(singlepoint memory position)。
发明内容
本发明涉及一种座椅滑轨组件,该座椅滑轨组件包括一个下滑轨构件和一个可移动地安装到下滑轨构件上的上滑轨构件。一个转动的凸轮安装到上滑轨构件上,并且一个凸板件安装到上滑轨构件上并从此处向外伸出。一个止动爪可转动地安装到凸板件上,用于适时地接合凸轮以便联锁凸轮,和适时地脱开凸轮以便为座椅滑轨组件提供一种记忆功能。
附图说明
以下参照附图的详细描述有助于更好地理解本发明的优点,其中:
图1是一个座椅组件的侧视图,该座椅组件由一个本发明的滑轨组件所支承并位于乘坐位置的舒适范围内;
图2是一个处于前伸位置的座椅组件的侧视图,其中,滑轨组件位于最靠前乘坐位置之前;
图3是一个座椅滑轨组件的立体图;
图4是一个座椅滑轨组件的一侧部分的立体图;
图5是一个移去上滑轨的图4所示的座椅滑轨组件的立体图;
图6是一个处于步进调节方式的座椅滑轨组件的侧向立体图;
图7是一个处于前伸位置的座椅滑轨组件的侧向立体图。
具体实施方式
参照图1,一个座椅组件整体地标记为10,用在机动车辆内。座椅组件10包括一个基本水平的座垫12和一个座椅靠背14。座垫12具有一个用于支承乘客的上表面16和一个相对的下安装面18。一个为本领域技术人员所普遍知晓的倾斜组件20将座椅靠背14可转动地互连到座垫12上,并在图1中A处所示的多个后仰位置和图2中的B处所示的前倾位置之间转动地调节座椅靠背14。
一个座椅滑轨组件22位于座椅组件10和标号为24的车辆底板之间,用于可滑动地支承座椅组件10。滑轨组件22在由最靠前乘坐位置和最靠后乘坐位置所限定的舒适范围内的多个乘坐位置之间,相对于底板24纵向步进地滑动调节座椅组件10。而且,随着座椅靠背14转向前倾位置B,滑轨组件22能使座椅组件随之移到舒适范围内的最靠前乘坐位置之外,到达如图2中的C处所示的前伸位置,以便能够方便地进入到车辆内座椅组件10之后的空间。再者,在优选实施例中,滑轨组件22也能使座椅组件从前伸位置C返回到预定单点记忆位置,如最靠后的乘坐位置。
更具体的是,参照图3,座椅滑轨组件22包括一个内侧滑轨组件26和一个与内侧滑轨组件26平行相隔的外侧滑轨组件28,内侧和外侧滑轨组件26、28各自在前端部32和后端部34之间纵向伸展,并各自包括一根大致U形的上滑轨30和一根大致U形的下滑轨36。正如本领域的普通技术人员所普遍知晓,上滑轨30可滑动地联锁到下滑轨36上,以便上滑轨30能相对于下滑轨36纵向地滑动。上安装支架42被固定在上滑轨30与座垫12的下表面18之间,用于将滑轨组件22安装到座椅组件10上。下安装支架44被固定在下滑轨36和底板24之间,用于将座椅组件10安装到车辆上。
滑轨组件22还包括一个锁止机构46,该锁止机构46可操作地连接到内侧和外侧滑轨组件26,28上各自的上滑轨30上,用于联锁上下滑轨30,36并阻止两者间的纵向滑动。锁止机构46可选择地在一个与上下滑轨30、36锁合的闭锁位置和一个与下滑轨36脱开并与之相隔一定距离的开锁位置之间移动。许多齿位于下滑轨36上,用于与锁止机构46锁合。锁止机构46可移动地安装到上滑轨30上,并具有至少一个包括一开口的凸缘。该凸缘伸进上滑轨30内,并且适时地啮合和脱开下滑轨36的齿,以便将上下滑轨30、36适时地保持在相应的闭锁和开锁位置上。换句话说,锁止机构46使座椅组件10的步进调节变得容易。一个偏置构件48、比如一个钢丝弹簧,联接在锁止机构46和上滑轨30之间,用于将锁止机构46偏置到闭锁位置处,并且相对于下滑轨36维持该上滑轨30的位置。偏置构件48继续偏移所述开口来与所述齿啮合。偏置构件48优选为一种钢丝弹簧,该钢丝弹簧具有一对安装到上滑轨30的末端和一个支承锁止机构46的中间部分。一根大致U形的释放杆50包括一根位于内侧和外侧滑轨26、28之间的中央握杆52和杠杆54、56,所述杠杆在相应的内侧和外侧滑轨组件26、28旁从握杆52处起伸展到上滑轨30靠近锁止机构46处。杠杆54、56与上滑轨30转动连接,并与锁止机构固定连接,用于在闭锁位置和开锁位置间控制锁止机构46。锁止机构46、偏置构件48和释放杆50都是本领域中的普通技术人员普遍知晓的技术。而且,应明白,锁止机构46可用在内侧和外侧滑轨组件26、28中的一个上或两者都用上;当然,在优选实施例中,在内侧和外侧滑轨组件26、28两者上都优选地使用锁止机构46,以保证上下滑轨30、36间的完全锁合。
为了在一个舒适的范围内步进地调节座椅组件10的纵向滑移位置,在释放杆50上施加一个向上的力,以使杠杆54、56向上转动并使后者与相应的锁止机构46啮合。锁止机构46抵抗弹簧48的偏置力从与上下滑轨30、36接合的闭锁位置被向下推至与下滑轨36脱开的开锁位置。这时,座椅组件10可相对车辆的底板24向前或向后滑移至用来限定舒适乘坐范围的最靠前位置和最靠后位置间的一个所希望的位置处。一旦座椅组件10移至一个所希望的位置,就去掉施加在释放杆50上的力,以使锁止机构46回到与上下滑轨30、36接合的闭锁位置,由此维持住座椅组件10的位置。
参照图3和图4,座椅组件10还包括一个座椅倾翻机构60,该倾翻机构60能使座椅组件10移向最靠前位置之外到达前伸位置C处,并且也能使座椅组件10从前伸位置C回到在舒适范围内的预定单点记忆位置,如最靠后位置。
座椅倾翻机构60包括一个凸轮盘62,该凸轮盘62具有一个第一端部64和一个第二末端部66,该两端部由基本平行的前后缘68、70来连接。一个倾斜部分72从后缘70处向上并向后伸出,并形成一个倾斜的或有坡度的凸起面,用于可滑移地接合锁止机构46。在倾斜部分72上靠近凸轮盘62的第二末端66处有一个凹口74。凸轮盘62的第一端部64由一个枢轴帽76可转动地连接到内侧滑轨组件26的上滑轨30上,以使得凸轮盘62从上滑轨30处在一个基本平行的水平面内向外伸向外侧滑轨组件28。凸轮盘62在一个非致动位置和一个致动位置之间绕上滑轨30转动,如图3和4所示,非致动位置的特点是,前缘68靠近上滑轨30而倾斜部分72朝前与锁止机构46相隔一定距离,如图7所示,致动位置的特点是,凸轮盘向后转至基本垂直于上滑轨30的纵向长度方向处,且与锁止机构46接合。参照图5和图6,枢轴帽76包括一个位于凸轮盘62之上的头部78和一个大致圆柱形的轴,该轴从头部78处伸至一个大致矩形的挡板80,该挡板80位于上滑轨30和下滑轨36间的空间内。枢轴帽76用键与凸轮盘62固定,并可与凸轮盘62一起在一个挡止位置和一个开启位置间转动,如图6所示,该挡止位置的特征是,矩形挡板80横向地位于上下滑轨30,36间的空间内,如图7所示,开启位置的特征是,矩形挡板80基本平行于上下滑轨30、36的纵向长度方向。一个偏置构件82、比如所示的螺旋弹簧连接在枢轴帽76的头部78和凸轮盘62的第一端部64之间,用于将凸轮盘62按反时针方向偏移至非致动位置,同时也将枢轴帽76按反时针方向转动地偏移至挡止位置。应该明白,换另一种方式,偏置构件82也可包括一个位于凸轮盘62的任何部分与内侧滑轨组件26之间的弹簧,用于使凸轮盘偏移至非致动位置。
一根钢索83连在凸轮盘62靠近后缘70处和座椅靠背14之间,用于随着座椅靠背14从某个倾斜的后仰乘坐位置转至前倾位置,将凸轮盘62随之从非致动位置反时针地转动至致动位置。按另一种方式,钢索83可连在凸轮盘62和一个在座垫12上或座椅靠背14上的释放手柄之间,用于使凸轮盘62从非致动位置转至致动位置。凸轮盘62也将枢轴帽76从凸轮盘62处于非致动位置时的挡止位置转至凸轮盘62处于致动位置时的开启位置。
座椅倾翻机构60还包括一个触发臂84,该触发臂84由一块位于上端部86和下挡端88之间的细长板构成。触发臂84由一个枢轴销91可转动地连接到一个支承支架90上,该枢轴销位于上端部86和下端部88之间。支承支架90由一种诸如螺栓、螺钉、焊接件之类的紧固件固定到上滑轨30上。如图3和4所示,一个偏置构件94、比如螺旋弹簧或钢丝弹簧连接在触发臂84和上滑轨30之间,用于使触发臂84按顺时针方向转至一个未栓住的位置处,该未栓住的位置位于靠近或紧靠凸轮盘62的倾斜部分72处且朝里与凹口74相隔一定距离。触发臂84的上端部86伸向凸轮盘62上方,而下挡端88伸向枢轴销91下方。触发臂84在其朝向凸轮盘62的后缘70上还包括一个凹口96,用于在凸轮盘62转至致动位置时与凹口74锁合。
在操作中,正常乘坐使用座椅组件10时,如前所述,滑轨组件22被用来在最靠前位置和最靠后位置间的舒适范围内纵向步进地滑移座椅组件。如图3-6所示,随着座椅组件10在舒适范围内移动,凸轮盘62由偏置构件82维持在非致动位置上,同时触发臂84由偏置构件94偏移至未拴住的位置。另外,枢轴帽76保持在挡止位置上,横向地位于上滑轨30和下滑轨36之间。参照图5,挡板80可在前端部32附近与从下滑轨36上凸出的前止动片100接合,从而限制上滑轨30的行程并限定最靠前位置。同样,挡板80可与一个从下滑轨36上凸出并限定最靠后位置的后止动片接合。
为了将座椅组件移动或滑动至前伸位置,如图1和2所示,座椅靠背14绕倾斜机构20从某一后仰乘坐位置A转至靠近座垫12的前倾位置B。钢索83由座椅靠背14拉动,从而将凸轮盘62从图4所示的非致动位置顺时针地拉转至图7所示的致动位置。触发臂84的前缘沿凸轮盘62的倾斜部分72滑动,而且触发臂84由凸轮盘62来推动,以使触发臂84逆着弹簧94的偏置力绕枢轴销91反时针地转动,直至凸轮盘62的凹口74与触发臂84的凹口96联锁,从而将凸轮盘62锁定在致动位置处。触发臂被转至大致直立的位置,其中,下挡端88在下滑轨36之下凸出向下。
另外,当凸轮盘62处于致动位置时,凸轮盘62的倾斜部分72可滑动地接合锁止机构46的顶部,从而将锁止机构46从与下滑轨36接合处向下推出至开锁位置。也就是,凸轮盘62由触发臂84保持在致动位置,从而将锁止机构46维持在开锁位置。这时座椅组件10可自由地沿下滑轨36滑移至前伸位置。
再者,凸轮盘62也将枢轴帽76从挡止位置转向如图7所示的挡板80平行于下滑轨36的开启位置。在开启位置下,挡板80自由地滑过下滑轨36上的前止动片100,并使上滑轨30继续前伸,直至挡板80与最靠前的止动隔板102接合,如图5所示,止动隔板102从下滑轨36的前端部32处凸出且用于限定前伸位置。因此,在座位组件10处于前倾位置和在舒适行程范围之外的前伸位置时,座椅滑轨组件22给座椅组件10提供了附加的向前滑动的行程。这使得能够充分利用在车辆内座椅组件10之后的空间。
为了让座椅组件10从前伸位置C回到在优选实施例中限定为最靠后位置的预定单点记忆位置,座椅靠背14首先从前倾位置B回转到某一后仰乘坐位置A处。由于凸轮盘62仍与触发臂84联锁在致动位置上,即使随着座椅靠背14回到乘坐位置,锁止机构46仍处于开启位置。因此,随着上滑轨30相对下滑轨36滑动,座椅组件10自由地向后滑移。如图4所示,当座椅组件10从前伸位置继续返回至预定单点记忆位置、亦即最靠后位置时,触发臂84的下挡端88在滑轨组件26的后端部34附近处与从下安装支架44上凸出的触发片104接合。当触发臂84继续向后行进通过触发片104时,触发片104与下挡端88接合并使触发臂84反时针地转离凸轮盘62的倾斜部分72。凹口96就从凹口74处脱开,从而使触发臂84从凸轮盘60处解锁。偏置构件82使凸轮盘62反时针地转离致动位置并返回到非致动位置上。在非致动位置处,凸轮盘62与锁止机构46分开并与之相隔一定距离,以致于偏置构件48使锁止机构46返回到与上下滑轨30、36锁合的闭锁位置,从而将座椅组件10锁定在最靠后位置,以便让乘客方便地坐进座椅组件10。然后,座椅组件10可如上所述再在舒适的范围内调节或再移向前伸位置。
以上是对本发明的说明性描述,应该明白,所使用的术语是出于描述语言的需要,而不是对本发明的限制。
依据以上的教导,可以对本发明进行各种修改和变换。因此,应该明白,本发明能以不同于以上描述的其它方式来实现。
