ABSTRACT:
A driving seat for use in an industrial vehicle such as a forklift, tractor and combine is disclosed. The driving seat comprises a seat back which is divided into two portions, i.e., upper and lower portions such that the upper portion can be folded backwards relative to the lower portion so as to lower the height of the seat back. The upper portion of the seat back is connected with the lower portion of the seat back by means of a rotary support device which is capable of performing such folding operation of the upper portion of the seat back by simply pressing against the upper portion itself.
