Abstract
Provided is a tilt arm for a seat that is applied to a vehicle seat and that moves in a pivoting manner when changing an angle of inclination of a front end portion of a cushion pad. The tilt arm includes a coupling arm portion pivotably coupled to a side frame of a cushion frame, and a leading-end-side arm portion coupled and fixed to a leading end portion of the coupling arm portion. A sectional shape of a fixed portion, where the coupling arm portion and the leading-end-side arm portion are coupled and fixed to each other, is a closed sectional shape formed by a closed curve. A sectional shape of the coupling arm portion at the fixed portion and a sectional shape of the leading-end-side arm portion at the fixed portion are each an open sectional shape that is partially opened.
