[0010] The rear transmission assembly includes a connecting rod and a connecting frame, wherein the connecting rod is installed on the rotating shaft, and the connecting frame is installed on one side of the connecting rod and connected to the vehicle body.

[0011] In a second aspect, a pickup truck seat adjustment method is provided, which is used in the pickup truck seat adjustment assembly described in the first aspect, and comprises the following steps:

[0012] Pull the seat cushion, the seat cushion drives the base to rotate on the vehicle body, and at the same time the seat cushion drives the backrest assembly to rotate to one side of the seat cushion until the seat cushion contacts the backrest assembly, and the seat cushion and backrest assembly are folded;

[0013] Rotate the rotating assembly, which drives the transmission rod to rotate. The transmission rod cooperates with the lower transmission assembly to drive the seat cushion to the side close to the base, and cooperates with the rear transmission assembly to drive the backrest assembly to the side away from the seat cushion, thereby adjusting the seat cushion and backrest assembly.

[0014] Pull the backrest assembly toward the side close to the seat cushion, and cooperate with the rear transmission assembly to drive the backrest assembly toward the side close to the seat cushion to fold the backrest assembly.

[0015] The present invention provides a pickup truck seat adjustment assembly. When it is necessary to fold the seat cushion and the backrest assembly, the seat cushion is pulled, and the seat cushion drives the base to rotate on the vehicle body. At the same time, the seat cushion drives the backrest assembly to rotate toward one side of the seat cushion until the seat cushion contacts the backrest assembly, and the seat cushion and the backrest assembly are folded; when it is necessary to unfold the backrest assembly and the seat cushion, the rotating assembly is rotated, and the rotating assembly drives the transmission rod to rotate. The transmission rod cooperates with the lower transmission assembly to drive the seat cushion toward the side close to the base, and at the same time cooperates with the rear transmission assembly to drive the backrest assembly to unfold toward the side away from the seat cushion, and the seat cushion and the backrest assembly are adjusted to unfold, thereby solving the problem that the backrest angle of existing pickup truck seats cannot be adjusted backward, resulting in poor riding comfort. When the backrest assembly needs to be folded, the backrest assembly is pulled toward the side close to the seat cushion, and the rear transmission assembly is used to drive the backrest assembly toward the side close to the seat cushion to fold the backrest assembly. During adjustment, the rear support assembly limits the backrest assembly to prevent the backrest assembly from occupying the rear cargo space. BRIEF DESCRIPTION OF THE DRAWINGS
