Adjustable seat for motor vehicle, has central base shaft and central backrest shaft that rotate lateral flanges and block rotations of flanges in different positions, and connecting rod connecting shafts with flanges

摘要

The seat has lateral flanges rotatively arranged on a base frame (8) and a backrest frame (10). A central base shaft (50) and a central backrest shaft (52) are arranged with respect to base and backrest cushions and rotatively mounted with respect to the frames, respectively. The shafts simultaneously rotate the flanges, and block the rotations of the flanges in different positions. Connecting rods (70, 72, 76, 78) connects the shafts with the flanges. An actuator (100) has an electric motor for driving and blocking the rotations of the shafts.
