ADJUSTABLE ARMREST MECHANISM

Abstract

The invention is an ergonomic and adjustable armrest mechanism (100) suitable for the physiological needs of the patient, for dialysis, blood collection chairs, birthing beds and similar medical chairs, and its features are: the chair body (120) to which the armrest mechanisms are attached, which is the main carrier structure on which all movable components are mounted and supported, connecting the armrest mechanism (100) to the chair; a lockable circular rotation mechanism to allow the armrest (101) to rotate 360 ​​degrees to the right and left on the horizontal axis to enable the patient to reach the most suitable position; and a stepped horizontal angle movement mechanism that offers a lockable movement system to allow the armrest (101) to move downwards on the vertical axis at certain angles to help keep the patient's arm in an ergonomic position.It includes a single body of circular rotation and stepped horizontal angle movement mechanisms (104) which combines the circular rotation mechanism and the stepped horizontal angle movement mechanism in a single structure for both space saving and stable operation; and an armrest (101) that can move at various angles with a single body of circular rotation and stepped horizontal angle movement mechanisms (104) to support the patient's arm and provide ergonomic comfort.
