Abstract:
A vehicle seat wherein debris can be inhibited from entering support brackets to which an armrest is coupled is provided. One aspect of the present disclosure provides a vehicle seat including a back frame and an armrest. The armrest includes side frames and a stopper pin. The back frame includes support brackets to which the side frames are pivotably coupled. The support brackets include guide slots that guide the stopper pin. On imaginary surfaces perpendicular to the seat width direction, loci of the guide slots formed on the side frames when the armrest pivots, the side frames and a portion of the stopper pin inserted into the guide slots are projected, and a diameter of a largest perfect circle that can be fitted into areas of the loci that do not overlap with the side frames and the stopper pin is smaller than widths of the guide slots.

Claim (Index 1):
A vehicle seat comprising:\n a seatback; a back frame forming a framework of the seatback; and an armrest configured to be pivotable between a stored position in which the armrest is stored in the seatback and an in-use position in which the armrest is folded down toward a front side of the seat, wherein the armrest comprises:\n two side frames disposed so as to be spaced apart in a seat width direction; and \n a stopper pin projecting outside from the two side frames in the seat width direction, \n wherein the back frame comprises two support brackets to which the two side frames are respectively pivotably coupled, wherein the two support brackets respectively comprise guide slots in which the stopper pin is inserted, the guide slots being configured to guide the stopper pin when the armrest pivots, and wherein, on an imaginary surface that is perpendicular to the seat width direction and defined for each of the two side frames, a locus of one of the guide slots of a corresponding one of the two support brackets, a corresponding one of the two side frames, and a portion of the stopper pin inserted into the guide slots are projected, the locus being formed on the corresponding one of the two side frames when the armrest pivots, and a diameter of a largest perfect circle that can be fitted into areas of the locus that do not overlap with the corresponding one of the two side frames and the stopper pin being smaller than a width of the one of the guide slots.
