The possibility of manipulating errors of an emergency or quick adjusting means shall be ruled out at least extensively in a linear drive. It is proposed for this purpose, for a linear drive with a spindle (), which can be rotatingly driven on the drive side by a motor (), where the rotary motion of said spindle in the direction of the driven side () of the linear drive can be converted into an at least essentially translatory motion of a gear member, which is in functional connection with the spindle (), and said linear drive is provided, furthermore, with a torsional connection between the gear member and a connection part. The linear drive can be connected with the connection part on a driven side () to a load, which is to be adjusted, the torsional connection being able to be released by an adjusting device in order to permit a motor-independent adjusting motion of the linear drive, even though structure for emergency and/or quick adjustment are present. The torsional connection is able to be released by an adjusting element of the adjusting device only for motions in always only a single, predetermined relative direction of rotation between the spindle and the gear member.

A threaded nut is provided for a linear drive having a rotatable spindle. The threaded nut is provided with a main nut, wherein the main nut is intended for being arranged with its internal thread on the external thread of the spindle, and is intended to perform a translatory displacing motion during a rotary motion of the spindle. The threaded nut has, furthermore, a safety nut, which is intended not to mesh by its internal thread with the external thread of the spindle during the normal operation of the linear drive and to mesh with the thread of the spindle in case of failure of the main nut. To make possible simple mounting in case of such a threaded nut means and to reduce the risk for incorrect alignment, the main nut () has a first part and a second part. The two parts are located at spaced locations from one another and each part being provided with a threaded section () of the main nut (), wherein the safety nut () is intended to be arranged between the two threaded sections ().
