Abstract

The invention provides a chair with getting-up assistance by self-action, which comprises two chair leg armrests, a chair seat and a backrest. An arc-shaped front end portion is disposed in front of the bottom of the two chair leg. An arc-shaped groove is disposed below the lower inner surface of the two chair legs. The arc-shaped groove is configured with a protruded arc-shaped guiding groove on the side. Both ends at the rear side of a footrest are protruded with round columns, wherein the round column may be sliding in the guiding groove and is pivoted with the front end of a rear pulling rod. The armrest is pivoted with two pressing rods. The front ends of the two pressing rods are pivoted with the front end of a front pulling rod, wherein the rear end of the front pulling rod is pivoted with the rear end of the rear pulling rod. Thus, when a user steps on the footrest to get up, the front bottom end of the chair receives the force and thus generates an initial forward-leaning action due to the arc shape; furthermore, by hand-pressing on the pressing rods of the armrests, the rear end of the front pulling rod is limited by the rear pulling rod to be abutted against the ground for further enabling the chair to lean forward, such that the getting-up may be easier by forwardly leaning the chair in cooperation with the getting-up action.
