[0032] A vehicle seat reclining apparatus according to an embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a view showing a seat reclining apparatus mounted on a seat. Fig. 2 is an exploded view showing an assembled structure of the seat reclining apparatus. Fig. 3 is a front view of the seat reclining device.

[0033] The base plate 1 is fixed to the cushion frame 30 by brackets (not shown). The cushion frame 30 serves as a seat bottom. The gear plate 3 is fixed to the seat back frame 20 by a bracket (not shown). The gear plate 3 is operatively fitted to the base plate 1 . The base plate 1 and the gear plate 3 are rotatably combined by a support plate 5 pressing the peripheries of the base plate 1 and the gear plate 3 . A space is defined in the axial direction between the base plate 1 and the gear plate 3 . Provided in this space are: three lock gears 7; a center cam 9 as a cam member; and a coil spring 11...

Abstract

A seat reclining apparatus includes: a base plate fixed to a seat bottom or a seatback and including a plurality of guiding portions extending in a radial direction of the base plate; a gear plate fixed to the seat bottom or the seatback, the gear plate rotatably assembled at the base plate and formed with internal teeth; a lock gear assembled at the base plate and guided by the guiding portions of the base plate to be movable in the radial direction, the lock gear being formed with external teeth engageable with the internal teeth of the gear plate. At least one external tooth, which is positioned at a front end or a rear end from a rearward tilting direction of the seatback, has a radius of a pitch circle being smaller than a radius of a pitch circle of the internal teeth of the gear plate.

Description

technical field [0001] The present invention relates to a seat reclining device for a vehicle. More particularly, the present invention relates to a seat reclining apparatus capable of adjusting an inclination angle of a seat back relative to a seat bottom. Background technique [0002] Generally, a backrest (seat back) of a front seat of a vehicle is inclined at an adjustable angle relative to a seat cushion so that a person seated in a passenger's seat and a driver's seat feels comfortable. Further, for a three-door type vehicle, the backrests (seat backs) of the front seats are tilted at an adjustable angle relative to the seat cushions in a manner in which the front seats are folded forward so that occupants can easily enter and exit the vehicle rear space. More particularly, according to the seat reclining apparatus disclosed in Japanese Patent No. 2645583 (see FIGS. 3-6 ), the base plate is attached to the seat cushion frame, and the rotating plate is attached to the...
