Abstract
The invention relates to a linear drive unit with a linear stroke (h) for adjusting parts mounted in movable fashion, particularly in items of furniture, having a housing (2), a transmission unit (3) driven by a motor and mounted in the housing (2), through which a torque of a first transmission element (4) can be converted into a linear movement of a thrust element (5), where the thrust element (5) is mounted coaxially and movably relative to the first transmission element (4), and is provided with an external thread (6) that engages an internal thread (7) provided on the first transmission element (4), and having two coupling elements (8, 9) for coupling the linear drive unit (1) to the item of furniture, where a first coupling element (8) is connected to the housing (2), and a second coupling element (9) to an end of the thrust element (5) designed as a coupling end (10), and where at least the coupling end (10) of the thrust element (5) passes out of the housing (2) through an outlet opening (11). According to the invention, the first transmission element (4) is designed as a hollow, cylindrical rotary body with an input section (12) and an output section (13). Furthermore, the output section (13) is axially remote or offset from the input section (12).
