The present application relates to an adjustment device for a vehicle seat, comprising a bracket member (7), a front linkage (30) and a rear linkage (40). The bracket member has an initial position in the stowed position of the front link mechanism and the first position of the rear link mechanism. The adjusting device further comprises a first drive system for driving the rear linkage, preferably comprising a first motor (11) coupled to the front linkage and a first screw-nut mechanism (21) comprising a first screw (22) and a first nut (23) coupled to the rear linkage. From the initial position, when the first driving system is locked and the front connecting rod mechanism is converted from the folded posture to the unfolded posture, the support component can rotate around the hinge point of the support component and the rear connecting rod mechanism. The invention further relates to a seat cushion framework comprising the adjusting device and a vehicle seat, and the seat cushion framework and the vehicle seat can be suitable for low-Block-value seat application environments.
