Rehabilitation Exercising Equipment Having Balance and Rotation Functions

Abstract

A rehabilitation exercising equipment includes a main frame, a pivot mechanism pivotally mounted on the main frame, and a seat unit mounted on the pivot mechanism to move in concert with the pivot mechanism. The pivot mechanism includes a rotation shaft rotatably mounted on the main frame, and two first bearings each pivotally mounted on the rotation shaft and each connected with the seat unit so that the seat unit is movable in concert with the two first bearings relative to the rotation shaft. Thus, the seat unit is pivoted leftward and rightward relative to the main frame and is swiveled horizontally relative to the main frame to achieve an exercising, balance or rehabilitating function.
