Abstract
Described herein is a recliner regulating device comprising a locking cam, an unlocking cam with a thickness less than the locking cam, a ratchet gear, a coulisse and a return spring connected with a central shaft. The locking cam is connected with the unlocking cam. Sliders are connected with the unlocking cam and sliding grooves. A jacket is connected with the ratchet gear and the coulisse. The return spring is connected with the coulisse. The thickness of the locking cam and the unlocking cam may be respectively designed in terms of the stress applied thereon. Since the locking cam and the unlocking cam are separately produced, structure of the die is simplified and service life of the die is improved significantly. The locking cam and the unlocking cam may be manufactured by punch, which leads to a greater production efficiency.
