摘要

The system for the adjustment of the seat back inclination relative to the seat part includes a pair of devices (2R,2L) on the right and left sides respectively. A connecting shaft (5) between the two devices enables their simultaneous locking and unlocking. Levers transmit the activating force to the shaft. The devices include lower (21R,21L) and upper (22R,22L) arms fixed to the seat frames and to the back frames respectively.
