The present invention is an Electric servo system which controls and automates gate openings based on GPS speed and position data that results in precise and reliable modern variable and constant rate application. The Electric servo system also allows for Mechanical gate linkages to remain intact, resulting in few changes to the aircraft and redundancy of emergency components. A Mechanical input connect/disconnect is used to effortlessly transfer between the automated Electric servo system and the Mechanical gate system.

A height-adjustable armrest for a chair, in particular an office chair, has an arm support, which is retained by an armrest holder. The armrest holder is pivotable and a pivoting causes the armrest to be adjusted in height. An arresting device fixes the armrest holder in a height position. The arresting device is arranged at the upper, alterable-height end of the armrest holder and has a linearly movable latching element. The latching element is connected via a guide element to the armrest holder such that each pivoting movement of the armrest holder induces a linear movement of the latching element.
