Abstract
A linear actuator especially for adjustable furniture comprises a spindle () with a spindle nut () for bringing about the adjustment of the article of furniture. At the end of the spindle () there is a bearing () for mounting of this in the actuator. The spindle/spindle nut () is driven by an electric motor () through a transmission (). For preventing accidents and/or damage during the adjustment of the article of furniture the actuator is equipped with a squeeze protection based on a piezo element (). This piezo element () is arranged in connection with the bearing () for registering the forces or deflections of the forces affecting the spindle (). In that the piezo element () has a through-going hole for the spindle the mounting of the piezo element () is simplified and further it has turned out that a particularly good signal/noise ratio is obtained.
