Abstract
The utility model belongs to the technical field of automobile seats, and particularly relates to a height adjuster of an automobile seat. The height adjuster comprises a shell. A spline shaft, a connecting disc and a gear shaft are installed in the shell. The outer end of the spline shaft stretches out of the shell and is provided with a connecting part matched with a control handle. The inner end of the spline shaft and the right side of the connecting disc are matched to form a first two-way clutch. The left side of the connecting disc and the inner end of the gear shaft are matched to form a second two-way clutch. The outer end of the gear shaft stretches out of the shell and is used for outputting torque. When the spline shaft of the first two-way clutch rotates, a self-locking protrusion abuts against a spring assembly to make a first rubber spring deformed, and a pin roller of the first spring assembly rubs against the inner wall of a clutch room of the connecting disc for self-locking matching; when the spline shaft continues to be rotated, the spline shaft drives the connecting disc through the first rubber spring and is reset through a return spring at the same time. Through the design, clutch transmission from the spline shaft to the connecting disc is really achieved, and the height adjuster is safe, reliable and good in practicality.
