Reclining angle adjustment device

摘要

A reclining angle adjustment device used to obtain best inclination of a reclining seat for passengers, including a seat back arm fixed to a seat back portion, a base arm with an internal gear connected with the seat back arm through an axis, a stopper, a regulating plate, the first control lever and the second control lever. For rough adjustment, the first control lever is inclined forwardly or backwardly by a passenger on seat so as to disengage the stopper from the regulating plate. For minute adjustment, the second control lever is repeatedly moved round upwardly and downwardly so as to roll a pinion in the internal gear provided in the seat back arm.
