摘要： A reclining mechanism of a seat is provided that includes a fixed flange, a mobile flange, and locking parts being placed on first guide seats of guide seats on a first side of the fixed flange to be slidable inwardly and outwardly between the guide protrusions. Each locking part includes a locking gear on an outer end and is configured to engage with the internal gear of the mobile flange when sliding outwardly, thereby inhibiting relative rotation between the mobile flange and the fixed flange. The reclining mechanism further includes a locking cam rotatably provided at a center of the fixed flange and sub-parts provided on second guide seats of the guide seats on the first side of the fixed flange to be slidable inwardly and outwardly between the guide protrusions, each of the sub-parts being divided into a first part and a second part by a slit.

摘要： A reclining device for a vehicle seat of the present disclosure includes a base plate provided with an assembling depression, a gear plate inserted into the assembling depression, a mobile flange transferring a torque to a seatback, and a power transmission module installed in a central portion of the gear plate to eccentrically rotate the mobile flange and to inhibit power transfer in an opposite direction. In particular, the reclining device further includes a stopper having a stop protrusion on the mobile flange and the stop protrusion is inserted into an arcuate stop hole formed on the base plate so as to efficiently realizes the stopper's function to limit the forward and backward rotation angle of the seatback to a predetermined range using fewer parts, thus reducing the weight and production cost of a reclining device.
