Description

用于机动车座椅的操纵单元
技术领域
本发明涉及一种用于机动车座椅的操纵单元，其具有：a)操纵元件；b)基件；c)枢转轴，所述枢转轴设置在基件和操纵元件之间，并且允许操纵元件相对于基件的枢转运动；d)弹簧，所述弹簧设置在操纵元件和基件之间，并且使操纵元件在静止位置上相对于基件的弹性预张紧。
背景技术
例如从US 2,285,616中已知一种这样的机动车座椅操纵单元。在此，基件构成为与座椅导轨(22)刚性地连接的梁(35)。操纵元件为具有锁定元件的锁定杆，所述锁定元件接合在连接在底部导轨(20)内的闭锁板条内。枢转轴平行于导轨的纵向调节方向设置，其伸过基件和操纵元件的支承孔口。最后设有弹簧，所述弹簧插在枢转轴上，一方面支撑在基件上，并且另一方面支撑在操纵元件上，并且使操纵元件在静止位置上相对于基件的弹性预张紧，其中该静止位置为在闭锁板条内的接合位置。
这样的操纵单元基本上证明是可行的，因为其已经使用了长时间。但是其具有缺点。装配耗费相当大。虽然能够简单地装配枢转轴，但是其必须通过附加的机构来防止轴向运动。这需要在枢转轴上的用于弹簧的容纳的附加的空间。在弹簧被推至枢转轴上后，弹簧必须单独地被钩住。所述已知的操纵单元具有许多单个构件。
发明内容
现在，在这里引入本发明。其目的在于，改进一种所述已知的操纵单元，在此简化储存和装配。
基于开头所述类型的操纵单元，该目的通过根据本发明的一种机动车座椅的操纵单元得以实现，其具有：a)操纵元件；b)基件；c)枢转轴，所述枢转轴设置在所述基件和所述操纵元件之间，并且允许所述操纵元件相对于所述基件的枢转运动；d)弹簧，所述弹簧设置在所述操纵元件和基件之间，并且使所述操纵元件在静止位置上相对于所述基件弹性预张紧；和e)座椅导轨，所述枢转轴和所述弹簧结合成一体，并且所述枢转轴和所述弹簧连接成具有轴件和弹簧区域的弹簧元件，并且在座椅导轨上，横向于导轨的纵向方向突起有两个支承块，所述两个支承块构成基件并且分别具有支承孔口。
根据本发明，迄今为止总是分开地构成的构件，即枢转轴和弹簧，现在结合成一体的弹簧元件。该弹簧元件连同其轴件共同构成枢转轴。该轴件也如现有技术的枢转轴一样相应地装配。但是，轴件不必通过例如在现有技术中使用的止动元件的附加的机构轴向卡紧，相反，轴件自身不与自己的止动元件相关联。轴件通过将弹簧元件的至少一个剩余的部分区域保持在至少一个位置上轴向卡紧。为此有利的是，在基件或操纵元件上设有固定弹簧的两个端部区域的保持装置。
弹簧元件的轴件最好也起到用于弹簧元件的弹性效果的支撑作用。因此，例如用于钩住如现有技术的弹簧的单独的支座变得多余。根据本发明的操纵单元弹簧件最好不再构成为螺旋形弹簧或蝶形弹簧，而是最好具有足够长的弹簧支腿，所述弹簧支腿提供用于枢转运动所必须的弹簧变形量。
弹簧元件最好具有与操纵元件弹性接触的支撑件。需要时在操纵元件的枢转操纵中能够进行相对于操纵元件的相对运动。
总体上，本发明允许以在现有技术中单独用于弹簧的装配所需的装配耗费来装配完整的组合构件，即弹簧元件。省去用于单独的枢转轴的装配和其轴向固定的装配耗费。
弹簧元件最好由具有圆形的横截面的杆状材料制造。横截面具有足够的尺寸，以便轴件具有在支承区域内的足够的横截面，例如横截面的直径最好大于1.5mm。
附图说明
本发明的另外的优点和特征可从本发明的不局限于现有的实施例的下面的说明中获得，所述实施例在下面参考附图详细地阐述。在附图中示出：

具体实施方式
如头三个实施例的根据本发明的操纵单元，即用于第一实施例的图1和图2的，用于第二实施例的图3至图5的，以及用于第三实施例的图6和图7的根据本发明的操纵单元分别设有用于纵向调节装置的导轨对。所述导轨对具有底部导轨20和座椅导轨22。在座椅导轨22内构成有窗口24。底部导轨20形成闭锁板条26。在座椅导轨22上，横向于导轨20、22的纵向方向突起有两个支承块28，所述支承块构成基件29并且分别具有支承孔口。
在下面，尤其说明第一实施例：其设有操纵元件30，所述操纵元件穿过窗口24插入座椅导轨22内。操纵元件30具有止动臂32，所述止动臂伸过座椅导轨22的剪切孔口34，并且与闭锁板条26接合。止动臂的自由端紧挨着座椅22的自由支腿。自由端能够与该自由支腿接触或不接触。操纵单元30具有向上弯曲的支承件36，在所述支承件中分别存在支承孔口。
基件29与座椅导轨22固定地连接。基件29由两个支承块28构成，两个支承决28由座椅导轨22的材料自由切割而成，并且从座椅导轨中弯曲出来，两个支承块分别具有支承孔口。
基件29的和操纵元件30的所述支承孔口对齐。弹簧元件40的轴件38穿过支承孔口插入。轴件38形成弹簧元件40的第一端部区域。此外，接着轴件38，弹簧元件40具有横向于导轨20、22的纵向方向延伸的横向件42。该横向件42就其而言过渡为支撑件44。在该支撑件上又连接有弹簧区域46。在弹簧区域46上连接有第二端部区域48，其穿过座椅导轨22的孔50插入，并且固定在该座椅导轨内。因此形成用于第二端部区域48的保持装置。
操纵元件30构成为双臂杆。外杆臂如在现有技术一样设置有手柄或与手柄连接(未示出)。支撑件44紧靠在外杆臂的底侧上。如果操纵元件30由所示静止位置并且根据箭头52枢转，以便释放锁定装置，那么弹簧区域46变形，在此也能够引起支撑件44相对于操纵元件30的移动。弹簧区域46能够为直线的，但是其也能够具至少一个弯曲部，如所示。弹簧区域构成为，使得在操纵元件30上存在希望的弹性力。
在下面讨论第二实施例，尤其是阐述与第一实施例的区别。在第二实施例中，基件29为与座椅导轨22连接的单独的部件。再次构成支承孔口。同样设有操纵元件30，所述操纵元件穿过座椅导轨的窗口24插入。但是现在，操纵元件自身不具有止动功能。相反，设有多个止动销32，如原则上能够从现有技术中已知，例如参见US 4,189,957。由止动销32中的至少一个的通常存在的闭锁位置，为此参见图4，所有止动销32克服接合弹簧54的作用自由拉至释放位置，通过在操纵元件30的内杆臂上设有的叉状构造使止动销32在底部接合和自由地挤压在轴环上，接合弹簧54也支撑在所述轴环上。接合弹簧54位于由导轨20、22封闭的通道空腔内。为了能够装配止动销32连同它们的接合弹簧564，从上面装配基件29，其具有用于止动销32的孔口，所述孔口与止动销32本身的直径相匹配，并且小于座椅导轨22的孔。因此，接合弹簧54能够支撑在基件29的底侧上。
基件29在与轴件38接触的区域内具有卷边，轴件38位于在所述卷边内，或者操纵元件30的部分区域横向于枢转轴的方向自由切割并且变形为，使得它们能够在上方接合轴件38，因此总体上，构成用于轴件38的通道。与第一实施例不同的是，支撑件44位于在外杆臂上构成的卷边内。因此支撑件的位置被固定。
如图6和7的第三实施例与第二实施例区别在于在插入轴件38时的装配方向。在第二实施例中，该装配从左侧，即在用于剖面V-V的箭头方面进行，而在第三实施例中，轴件38从右侧插入。为了允许轴件从右侧插入，那么在基件29的另一侧上得到横向件42，并且那么在横向件42和支撑件44之间附加地设有弹簧元件40的部分件，所述弹簧元件平行于轴件38或支撑件44延伸。那么弹簧元件40延伸为S形。
第四实施例示出操纵元件，如其在座椅的另一个位置上，即在纵向导向装置外使用，例如止动凸轮，如其在DE 10 2005 026 861 A1中作为构件(64)已知，止动凸轮用于将靠背固定在向前前倾的位置上。但是，操纵元件也能够承担其它的功能，例如用于座椅前倾的释放的手柄，如在DE 10 2004 057 106 A1中作为构件(32)已知。
现在，基件29为座椅支座的或靠背支座的或座椅的另一个构件的部分件。操纵元件30构成为凸轮。其能够围绕枢转轴转动，所述枢转轴限定轴件38。该轴件38伸过在基件29内的支承孔和操纵元件30内的支承孔。轴件38再次形成弹簧元件40的第一端部区域。连接在这里的横向件42固定在向上挤压的挡板56的下方，所述挡板由操纵元件30的材料压出。尽管向下看，能够由此脱离，即通过围绕枢转轴逆时针旋转，但是基于弹簧元件40的弹簧力被阻止。弹簧元件40紧接着卷绕一圈半，并且紧接着向右过渡为第二端部区域48。该第二区域在底部接合保持件58，所述保持件与挡板56类似地构成，但是指向相反方向，并且现在由基件29的材料形成。可能的是，只要继续装配，那么就向下挤压挡板56和/或在自由端上的保持件58，以便因此机械地固定横向件52或第二端部区域48。
设有止挡60，其中凸轮，即操纵元件30弹性地紧靠在所述止挡上。止挡60从基件29突起。
