Description

车辆座椅的纵向调节器 技术领域
本发明涉及一种用于车辆座椅、尤其用于机动车辆座椅的纵向调节器，以及一种车辆座椅。
背景技术
从现有技术已知纵向调节器，其中，齿轮机构安排在齿轮箱中并且与该纵向调节器的座椅导轨耦合。
发明内容
本发明的目的在于，提出一种相对于现有技术改善的用于车辆座椅的纵向调节器以及一种改善的车辆座椅。
在该纵向调节器方面，根据本发明的目的是通过权利要求1的这些特征来实现的。在该车辆座椅方面，根据本发明的目的是通过权利要求13的这些特征来实现的。
用于车辆座椅、尤其用于机动车辆座椅的用于机动地纵向调节该车辆座椅的纵向调节器包括一个导轨安排，该导轨安排具有座椅导轨的两个导轨对，其中，相应的导轨对包括一个第一座椅导轨和一个相对于该第一座椅导轨可移动的第二座椅导轨。此外，该纵向调节器包括：一个电机单元；一个具有至少一个齿轮转轴的齿轮单元，该齿轮转轴至少与这些对之一的第一座椅导轨牢固连接；以及一个与该齿轮转轴共同作用的可旋转的齿轮元件，例如蜗轮。该纵向调节器还包括：一个传输单元，该传输单元既与该齿轮单元、也与该电机单元耦合以将该电机单元的扭力传输到该齿轮转轴上；和一个至少部分地容纳该齿轮单元的齿轮箱；以及一个用于接收该齿轮箱的支架。在此，该支架与该齿轮箱一起安排在一个导轨对的该第一座椅导轨与该第二座椅导轨之间构成的空腔中，并且穿过该第二导轨中的导轨开口从该导轨开口至少部分地以如下方式伸出，使得该支架关闭该第二导轨中的导轨开口。
在一个可行的实施方式中，该支架以如下方式形成，使得该齿轮箱安排在该支架的两个固定支腿之间，这些固定支腿在纵向方向上彼此间隔开并且竖直地延伸。在此，这两个固定支腿尤其与该第二座椅导轨耦合，尤 其与该第二座椅导轨至少形状配合地或力配合地连接。
在另一个实施方式中，该支架形成为U形的，其中，该U形形成的支架的支腿开口指向该第一座椅导轨的方向，并且一个通过这些固定支腿构成的中间空间包括该齿轮箱。由此，该齿轮箱关于该第二座椅导轨的上侧(即，该上部导轨)借助于该支架的连接这两个固定支腿的区段被覆盖。该U形的支架例如具有卡箍元件和/或鞍座(Sattelhalterung)的形状。此外，这些固定支腿中的每个具有一个用于使该齿轮转轴贯通的通过开口。
通过本发明实现的优点尤其在于，该纵向调节器能够借助于根据本发明的支架在很大程度上形成为紧凑的。由此，尤其可以形成相对于常规导轨安排实质上更平坦且更紧凑的导轨安排。为此，例如省去用于固定和保护该齿轮箱的额外的增强元件和覆盖元件。由于旋紧在该齿轮转轴上的齿轮元件(蜗轮)所需的(在竖直方向上的)安装高度，该齿轮箱例如从该第二座椅导轨的上侧伸出。
在该纵向调节器的改进方案中，该U形形成的支架至少形状配合地、力配合地和/或材料配合地与该第二座椅导轨连接。这些固定支腿和连接这些固定支腿的区段的外部轮廓尤其相应地与该第二座椅导轨的导轨形状特征(尤其导轨内部形状特征)相匹配。由此，不需要其他紧固元件(例如螺钉或铆钉)来紧固该第二导轨(尤其上部导轨)的支架。借助于该支架的对应于该导轨内部轮廓/导轨内部形状特征的此类外部轮廓，该支架可以在内侧形状配合或力配合地、例如夹持或夹紧地固持在该第二导轨内。由此可以减少安装时间并且降低材料成本。
在一个可行的实施方式中，该支架力配合或形状配合地固持(尤其夹持或夹紧地固持)在该第二导轨的导轨开口中。为此，这些固定支腿例如形成为挠性的。这些固定支腿例如以弹性的夹持臂的形式形成，其中，在通过指向该导轨开口的这些固定支腿来***该支架时，抵抗弹簧力将这些固定支腿向内压。在***后状态下，这些固定支腿自动弹性地向外咬合并且将该支架夹持在该导轨开口中。换言之：该支架例如固持在该导轨开口中的夹持座中。
额外地或替代性地，该支架可以力配合或形状配合地固持(尤其夹持或夹紧地固持)在该第二导轨的侧壁中的凹陷中。
在此，该纵向调节器可以以如下方式形成，使得该第二座椅导轨包括多个凹陷。该座椅导轨的上侧具有至少一个凹陷作为该导轨开口，该导轨 开口用于接收该U形形成的支架的连接用区段。通过在该上侧中形成的导轨开口，在纵向方向和横向方向上例如降低该第二座椅导轨的机械强度和负载能力。
通过具有闭合区段的U形支架(也称作固持卡箍)尤其关于该竖轴颠倒的安排(在该支架的***后状态中从该第二座椅导轨向上伸出)，简单地关闭该导轨开口并且向外覆盖该齿轮箱。
在此，该颠倒安排的U形支架能够至少形状配合或力配合地安排在该第二座椅导轨的导轨开口中并且用作该第二座椅导轨的增强元件。此外，该齿轮箱的从该第二座椅导轨的上侧伸出的箱体区域由该支架覆盖并且被保护免受外部影响。由此，该U形支架设置为用于紧固和定位以及覆盖该齿轮箱并且用于增强该第二座椅导轨。
此外，扩大了在该U形支架下方的空间，尤其在该第一座椅导轨(下部导轨)与该支架之间的空间。为此，这些固定支腿例如向外伸展并且相对彼此以预定的支腿角度安排。由于该U形支架的翻转的安排，这个扩大的空间尤其位于该连接区段的下方并且向内指向该导轨内部空间且构成该导轨内部空间。由此，该纵向调节器的其他部件可以安排在这些由此重新构成的内置安装空间中。
该支架例如具有17.8mm的(在横向方向上的)宽度、32mm的(在竖直方向上的)高度以及29.4mm的(在纵向方向上的)长度。该齿轮箱的上侧与该支架的下侧的间距例如可以为1.7mm。由该支架、具有该齿轮元件的齿轮箱组成的构造单元的总重量例如为66.9g。
在一个改进方案中，该齿轮箱的箱体侧部可以在很大程度上形成为狭窄的，使得该齿轮箱具有在15mm至20mm范围内的(在横向方向上的)宽度，例如为17mm；在20mm至30mm范围内的(在竖直方向上的)高度，例如为27mm；以及在20mm至26mm范围内的(在纵向方向上的)长度，例如为24mm。具有安排在该齿轮箱内部的齿轮元件的齿轮箱的重量例如在30g至38g的范围内，例如为34g。
此外，该U形形成的支架能够以简单的方式进行生产。例如，该U形的支架能够借助于注塑法或压制方法和/或折叠方法进行生产。
该纵向调节器的一个可行的实施方式提出，这些固定支腿分别包括至少多个安排在侧向边缘区域处的突出部，其中，相应的突出部的形状对应于该第二座椅导轨的侧向凹陷的形状。这些突出部尤其相应地安排在这些 固定支腿的一个下部的侧向边缘区域中。此外，这些突出部相应地形成为阶梯状的
Figure PCTCN2018083717-appb-000001
该支架至少力配合或形状配合地固持(尤其紧固)在该第二座椅导轨中。
在一个改进方案中，这些突出部至少挠性地形成，例如由塑料构成，其中，这些突出部固持(尤其夹持、卡锁或咬合地固持)在这些对应的凹陷中以进行形状配合或力配合的连接。在另一个实施方式中，这些突出部例如形成为分级的(stufig)。这能够实现在组装该纵向调节器时对该纵向调节器的部件的预锁定，例如为了这些部件的取向，并且能够实现在该纵向调节器的这些部件的组装状态中的主锁定，并且由此实现这些部件的彼此固定。
在另一个实施例中，该齿轮箱至少与该U形形成的支架的固定支腿连接。由此，尤其在该第二座椅导轨实施纵向移动时该齿轮箱由这些固定支腿支撑。
额外地，在纵向方向上看，该导轨开口在对置的开口侧分别具有一个用于该向外伸展的固定支腿的止挡元件。替代性地或额外地，每个固定支腿可以在其支腿外侧处具有一个向外指向的锁止鼻，该锁止鼻例如以卡锁的方式接合到相关联的止挡元件中。
在一个改进方案中，车辆座椅配备有前述纵向调节器，用于机动地纵向调节该车辆座椅。
