Abstract:
A seat lifter structure which can maintain the engagement of the gear of the sector and the pinion of the brake unit and prevent a fall down of the seat back to a front side, even when a large force to a front side is exerted with respect to the seat back is provided. It raises or lowers a cushion seat (ST 1 ) by raising or lowering a side frame ( 2 ) built into the cushion seat (ST 1 ) with respect to a fixing member ( 61 ). It is equipped with a brake unit ( 8 ) having a pinion ( 8 b ) and attached to the side frame ( 2 ); a sector ( 7 ) supported to be rotatable with respect to the fixing member ( 61 ) by a first support portion ( 7 b 1 ), supported to be rotatable with respect to the side frame ( 2 ) via a second support portion ( 7 k 2 ), having a gear portion ( 7 a ) to be engaged with the pinion ( 8 b ) and provided in parallel and facing with respect to the side frame ( 2 ); and a spacer ( 10 ) having a first surface ( 10 kb ) facing with the side frame ( 2 ) and a second surface ( 10 ka ) facing with the sector ( 7 ), which is installed between the side frame ( 2 ) and the sector ( 7 ).

Claim (Index 11):
A seat lifter structure for raising or lowering a cushion seat by raising or lowering a side frame built into the cushion seat with respect to a fixing member, the seat lifter structure comprising:\n a brake unit comprising a pinion, said pinion being attached to said side frame; a sector supported by a first support portion, wherein said sector is rotatable about a rotation axis with respect to said fixing member, said sector being supported via a second support portion, wherein said sector is rotatable with respect to said side frame, said second support portion having a gear portion to be engaged with said pinion, said second support portion being parallel to said side frame and said second support portion facing said side frame; and a spacer having a first surface facing said side frame and a second surface facing said sector, said spacer being arranged between said side frame and said sector, said sector having a sector surface defining an opening, said sector surface extending in an axial direction with respect to said rotation axis, said spacer being attached to said side frame, said spacer having a base portion and a protruding portion protruding from said base portion, at least a portion of said protruding portion being arranged in said opening, said protruding portion having an outer surface portion, said outer surface portion being in direct contact with said sector surface, one side of said base portion being in direct contact with said side frame and another side of said base portion being in direct contact with said sector, said one side of said base portion being located opposite said another side of said base portion.
