Embodiment Construction

[0031] figure 1 Designated with 1 is a motor vehicle which has a tailgate 3 which can be pivoted from a closed position to figure 1 The open position shown is, if appropriate, pivoted again to the closed position. The tailgate 3 can also be pivoted by eg two adjustment devices 5 arranged on opposite sides of the tailgate 3 .

[0032] The adjusting device 5 according to the invention can also be designed for actuating a side door of a motor vehicle. It is also conceivable to provide an adjustment device or an actuation for the sliding sunroof in the area of ​​the hinge shaft of the tailgate. Furthermore, automatic seat adjustment can also be performed by means of the adjusting device of the present invention.

[0033] In the illustrated embodiment, the adjusting device 5 is connected via a first connecting device 7 to the body 9 of the motor vehicle 1 and via a second connecting device 11 to the tailgate 3 . The connected devices 7, 11 can be corner joints. The connection ...

Abstract

The invention relates to an adjusting device for automatically actuating a door (3) of a motor vehicle (1), said device having a first tubular housing (15) connected to the body (9) of the vehicle (1) and A second tubular housing (25) connected to the door (3) to be adjusted, capable of being telescopically moved relative to the first housing (15), and a spindle drive (21 ), comprising: a spindle (27) capable of being rotated by an electric motor drive disposed in the first tubular housing (15), a spindle nut (31) threadedly engaged with the spindle (27), which The shaft (27) is displaced from a retracted rest position to an extended position along the longitudinal axis (A) of the mandrel (27) as it is rotated, a push rod (33), which supports the mandrel nut, which moves along the mandrel (27) ), the pushrod (33) is coupled to the second tubular housing (25), and the tubular guide (39) surrounds the pushrod (33) and the spindle nut ( 31) for guiding the spindle nut (31) during its axial displacement. According to the invention, said guide (39) is provided with a shape complementary to that of the spindle nut (31) in order to ensure that the spindle nut (31) does not rotate relative to said guide (39) and that said guide The parts are manufactured by a plastic forming process on a suitable metal tube.

Description

technical field [0001] The invention relates to an adjusting device with a spindle drive for automatically actuating a door of a motor vehicle. [0002] Herein, "vehicle door" as used herein should be understood to include, not only side doors, but also a tailgate or a trunk lid of a vehicle. Background technique [0003] It is known to use an adjusting device with a spindle drive for automatically opening and closing a side door of a motor vehicle, the spindle drive comprising a spindle rotatable by an electric motor drive, the spindle nut being rotated on the spindle The guide is displaceable along the longitudinal axis of the mandrel from a retracted rest position into an extended position. [0004] Such adjustment devices generally comprise a first tubular housing having an electric motor drive and a second tubular housing coupled to the spindle nut and telescopically movable relative to the first housing. Thus, two connection means are provided for connecting the firs...
