    • An electromotive linear drive (10), in particular for adjusting parts of an item of furniture, having a multi-part housing (14) which is produced from plastic in an injection-molding process and in which are mounted at least one drive train and a block-shaped spindle nut (13) which engages at least partially around the housing (14) and/or at least partially into the housing, should be designed such that the structural design is extremely simple and can furthermore, for installation in particular into a chair, be produced in a compact and also cheap manner from as few components as possible. According to the invention, the housing (14) is formed from at least two housing parts (14a and 14b) and has sliding tracks for the spindle nut (13), wherein at least the thread flights of the spindle (12) are arranged outside the housing (14). In one preferred embodiment, the housing (14) is arranged below the region of the spindle (12) in relation to the assembled position of the electromotive linear drive. The housing parts (14a and 14b) forming the housing (14) are of identical or similar, preferably shell-shaped, design in cross section.
    • 甲电动的直线驱动器(10),特别是用于调节家具物品的组件,其包括一多部件,由塑料注射模制的壳体(14),其中,至少一个驱动系安装和块状主轴螺母(13)的(壳体14 )至少部分地接合周围和/或至少部分地在所述壳体接合的设计应使得结构设计非常简单,这也是安装在特别是在椅子紧凑,并产生从少部件而且便宜。 根据本发明,至少两个外壳部分的外壳(14)(14a和14b)形成,并且具有用于所述主轴螺母(13),其中,至少所述外壳(14)的外侧主轴(12)的螺纹布置成滑动轨道。 在一个优选的实施方案中,壳体(14),基于下面的主轴的范围的电动的直线驱动器的安装位置(12)被布置。 所述壳体(14)在所述壳体部分(14a和14b)被配置为在相同或在横截面相似的,优选杯状的。
