Abstract

The invention relates to a vehicle seat recliner that includes: a plate frame of a first clamping lug formed on at least more than one guide block in the plurality of guide blocks; a sector gear having an inner gear formed on the inner peripheral surface thereof; ratchet-shaped gears that move between the pair of guide blocks, and a clamping ring is formed on one side of the inner peripheral surface of each ratchet-shaped gear; an operation cam formed by protruding a second clamping lug; and a return spring which is spiral, the inside end of the central part of the return spring is being clamped and supported on the first clamping lug, and the outside end is being clamped and supported on the second clamping lug. A supporting protruding block which is in point contact with the inner side face of the central part and supports the central part is formed on the operation cam in a protruding mode, so that the return spring is rolled up and generates elastic force when the recliner is unlocked, the inner peripheral surface of the inner side of the return spring is in point contact with the supporting protruding block, friction with the return spring is reduced, and operation force of the recliner is improved.

Description

technical field [0001] The present invention relates to a vehicle seat recliner, in particular, a vehicle seat recliner that minimizes the contact surface supported by the inner side of a three-point-supported return spring, thereby improving the operating sensitivity of the recliner. Background technique [0002] Generally, the recliner of a car is a device used on the seat to adjust the angle of the seat back to the seat cushion according to the body shape or convenience of the occupant. [0003] Korean Registered Patent Publication No. 10-0513576 discloses a lever type recliner among the recliners. [0004] figure 1 It is a schematic diagram showing an example of a conventional recliner disclosed in Korean Registered Patent Publication No. 10-0513576. [0005] As shown in the figure, in the conventional recliner, a sector gear (30) is rotatably coupled to the guide bracket on the inner surface of the groove portion of the plate frame (20). Between the plate frame (20) ...
