A locking device for a vehicle seat with a seat frame and a seat height adjustment device has two guide links fixed to the body, with a swivel support on a horizontal axis. The guide links can swivel in different angular positions for adjusting the height of the seat. One guide link has a geared unit for swiveling it, while both the guide links are connected to each other by means of a connecting rod so that they do not rotate with respect to each other. A locking device with an inertia-sensitive element works on the side opposite to that of the geared unit between seat frame and adjacent guide link. A spring working on the inertia-sensitive element keeps the locking device in the normally unlocked position. The inertia-sensitive element is a locking element for latching with an interlocking element. The locking element is under a pre-load by the spring, which moves it, while in the state released from its contact with the locking element, into a interlocking position with the guide link which fixes the guide link so that it does not rotate once the inertia sensing element senses inertia.
