ADJUSTABLE SEAT FOR DRIVING OPERATOR

The driving seat (10) comprises a seat base (31) and a backrest (32) forming a support structure (30). The backrest is articulated on the seat base around a backrest inclination axis (310), so as to allow an adjustable backrest inclination angle (Beta). The seat base (31) comprises a rear seat panel (33), of fixed inclination and a front seat panel (34) whose seat inclination angle (Alpha-A) with respect to the rear seat panel is modifiable. The backrest (32) comprises a lower backrest panel (35) and an upper backrest panel (36) whose lifting angle (Alpha-D) with respect to the lower backrest panel is modifiable. During use of the seat, the backrest inclination angles (Beta), seat inclination (Alpha-A) and lifting (Alpha-D) are modified to adapt the configuration of a seat into a working configuration, a standby configuration, a rest configuration or a crash configuration.
