Abstract

一种用于车座、尤其是机动车车座的配件(1)，其具有第一配件部件(11)，以及安装在第一配件部件(11)上并可相对于第一配件部件(11)绕中心轴线(A)旋转的第二配件部件(12)，而且还具有连接在第一配件部件(11)上并接合于第二配件部件(12)之上以便将第二配件部件轴向固定的扣环(21)，中间圆环(31)设置在扣环(21)和第二配件部件(12)之间。

Description

用于车座的配件
本发明涉及一种用于车座的配件，具体涉及一种具有权利要求1所述特征的机动车车座。
这种类型的配件从DE 10105282A1中可知。为了使两个配件部件无阻碍地相对转动，在这二者之间设置游隙。当配件用作机动车车座靠背的倾度调节器时，用于部分补偿靠背重量的靠背补偿弹簧就确保靠背即使在靠背没有受到负载的情况下，游隙也不会引起任何不良噪音(卡嗒声)。如果噪音在无靠背补偿弹簧的情况下也可以得到抑制，那么本配件的其他用途也是合乎要求的。
本发明的目的是改进上述类型的配件。根据本发明，通过具有权利要求1所述特征的配件来实现这个目的。优选实施例在从属权利要求中进行了描述。
因为中间圆环设置于扣环和第二配件部件之间，所以，促动所需的游隙能够在这样的方式下得到补偿，这种方式使得，即使没有靠背补偿弹簧，也不会有干扰性的卡嗒声发出。为了减少磨损，也就是为了将磨损限制在少数特定区域，中间圆环优选通过可旋转地固定在第二配件部件或扣环上而被驱动。如果第二配件部件承担了这种作用并且中间圆环承靠于其外部，那么配件的装配就较为简单，而且因此降低了成本。
一方面，在圆周方向上运转的中间圆环的侧面优选确保中间圆环由第二配件部件驱动；这通过在侧面设置至少一个凹口实现，该凹口容纳了设置在第二配件部件上的径向凸出的凸耳，以便允许确定的接合。另一方面，该侧面还通过与至少一个在径向上与扣环弹性接触的弹簧片凸起相配合，来补偿径向游隙以及公差。尽管这样，仍存在可用于防止配件卡住的足够游隙。中间圆环优选还具有轴向定向的端面，利用该端面，中间圆环优选用作轴向滑动的元件，即，通过确保第二配件部件和扣环之间较低程度的摩擦来实现。然而，中间圆环可以进一步简化设计，使得它仅可实现部分作用，例如，可以不设置弹簧片凸起。
例如与DE 10120854C1相比，根据本发明的中间圆环优选设置在第一配件部件上，位于第二配件部件支撑件的外部；因此，中间圆环就位于作用力路径的外部。这种设置不但确保了低的载荷应力和较低程度的磨损，而且这也使得中间圆环优选可利用塑料来制造，这就使得制造成本和重量下降。但是，对于特定的应用而言，中间圆环仍可以由金属制成。在一个不同的实施例中，中间圆环可以设置在第二配件部件和第一配件部件的支撑件附近，因此至少在碰撞发生的情况下，中间圆环位于作用力路径的外部。
据本发明所述的配件可以用于各种各样广泛的用途，例如使车座靠背枢轴式地转动，以及调节大腿部支撑件的倾斜，或者用于车座的任何其他折叠和锁定部分。配件可以是例如在DE 10105282A1中所述的掣子型配件，或者可以根据采用在德国专利DE 10120854C1中所描述的齿轮接合型配件，其具有两个内部齿轮和一个中央行星齿轮。
在下文中，以在附图中描述的两个示例性实施例为基础，来更详细地描述本发明，其中，
图1是部分组装的第一示例性实施例的分解视图，
图2是从轴向看去的中间圆环的视图，
图3是图2中沿线III-III的截面图，
图4是未设扣环的示例性实施例的局部视图，
图5是沿着图4中的线V-V的截面图，
图6是根据图1所示的第一示例性实施例的透视图，
图7显示了装备有示例性配件的车座，以及
图8是第二示例性实施例的局部视图。
在第一示例性实施例中，设计成掣子配件的配件1包括大致圆盘形的第一配件部件11和同样大致圆盘形的第二配件部件12，这两个配件部件可彼此相对地围绕中心轴线A旋转。下述方向数据参考中心轴线A确定的柱面坐标系。
如DE 10105282A1中描述，该专利公开的内容明确地涵括在本文中，导向和支撑段在第一配件部件11上形成。一方面，这些导向和支撑段在它们的外圆周面上支撑第二配件部件12，该第二配件部件具有带齿状缘边的环形齿轮结构，另一方面，这些导向和支撑段在它们之间至少载带一个齿状锁杆，而在本示例中载带两个可径向移动的齿状锁杆，所述锁杆与第二配件部件12的齿状缘边协同动作，以便锁定配件1。
一方面，扣环21包括在圆周方向上运转的侧面，并且扣环连同该表面承靠在第一配件部件11的径向朝外面向的圆周面上，并且刚性地连接在该圆周面上。扣环21也可以与第一配件11形成为一体。另一方面，扣环21在其定向成背向第一配件11的面端部设有凸缘状的缘边23。所述的缘边形成了环形端面，该端面接合于第二配件部件12上，从而将其固定在轴向上。在径向上，在第二配件部件12与扣环21之间设置间隙，以便允许第二配件部件12无阻碍地旋转运动。
由塑料制成的中间圆环31设置在第二配件部件12上，处于第二配件部件12与扣环21之间的区域中。对应于扣环21，所述中间圆环具有侧面33以及与之相连的环状端面35。利用这个横向于轴向的端面35，中间圆环31就用作在第二配件部件12与扣环21之间轴向滑动的元件。
侧面33在圆周上均匀地分布了若干凹口37，并且所述凹口容纳第二配件部件12上的径向凸出的凸耳38。这就确保了中间圆环31被第二配件部件12以可旋转地固定的方式来驱动。弹簧片凸起39在每两个凹口37之间形成。所述弹簧片凸起从侧面33上径向凸出，并弹性地贴靠在扣环21的内表面上。结果，配件部件11和12的任何公差、例如不圆或偏心就得到补偿，而不会阻碍这两个部件之间的相对旋转。此外，弹簧片凸起39具有缓冲效应。由于弹簧片凸起挠曲，并且中间圆环31未处在配件11和12之间的安装位置而位于作用力路径的外部，因此弹簧片凸起不会受到任何应力载荷，例如在碰撞发生的情况下出现的应力。
根据本发明，配件1可以用在机动车车座41中，例如用于调节靠背43的倾度，用于将靠背折叠到椅面位置或者用于以任何其他方式使靠背绕轴旋转。为了这个目的，通常可用手促动的控制杆49设置在传动杆上并与中心轴线A对齐，位于根据本发明所述的两个配件1之间，并且确保所述配件同步解锁。
第二示例性实施例涉及配件101，除非另外指出，否则该配件与配件1相同，出于此原因，同样的以及相同功能的组件由加上数字100的标号来表示。然而，在这种情况下，第二配件部件112在第一配件部件上的安装位置定位成紧邻于扣环。中间圆环131相对于该安装位置在轴向上稍微偏移，并且其端面135的相反侧在轴向上与第二配件部件112相接触。在这种情况下，中间圆环131具有位于其侧面133轴向延伸部分上的弹簧片凸起139，所述弹簧片凸起容纳在第二配件112的作为安装位置的圆周面的凹口中。通常，弹簧片凸起139在这个圆周面之上径向地凸出以便补偿游隙，但在发生碰撞的情况下，所述弹簧片凸起被压入凹口中，因此，弹簧片凸起139以及整个中间圆环131都位于作用力路径的外部。
