The driver's seat in the Tiger I was a standard component used in many panzers.
The bottom of the seat had two hooks and two pegs which fit into an underlying support. The form of the support differed widely in different vehicles; for example, in the Panther it was a flat plate. In the Tiger I, the support for this seat was a metal frame.
The frame had a series of holes, allowing the seat to be easily unhooked and shifted forwards or back. The total possible adjustment was 120mm.
The frame was bolted to metal blocks welded on the floor.
The frame was designed to fit between the torsion bars and other controls on the hull floor of the Tiger. In fact one of the metal blocks had to be displaced. This diagram shows only the torsion bars.
The position of the seat was 510mm from the center line. So it did not line up exactly with the driver's visor, which was 500mm from center.
With the frame directly bolted to the hull, there was no protection from shock.
There was no provision for vertical adjustment. In fact the frame in the Bovington vehicle was raised 40mm by small metal blocks inserted under the legs, as shown here.
