Regulating method for handrails of car seat

The invention discloses a regulating method for handrails of a car seat. The regulating method comprises the following steps: inwards pressing the handrails (1) of the seat, so that rotary pin shafts of the handrails (1) are connected with an output shaft end of a motor (3) to realize synchronous rotation; pressing down an electric button (4), and releasing the electric button (4) to select a next recording button (5) for recording a position signal by virtue of a recording system after the motor (3) drives the handrails (1) to be rotatably regulated to proper positions; while people sit in the seat again, only re-pressing down the recording button (5) which is correspondingly marked previously for carrying out position comparison; if the position is consistent with the previous recording position, not regulating; and if the position is inconsistent with the previous recording position, automatically switching on the motor (3) to rotate for driving the handrails (1) to rotate, and stopping rotating the motor (3) when the motor rotates to a standard position in a recording system. The regulating method is simple and convenient, labor-saving, and greatly enhances comfort of a driver.
