A calf rest for a patient chair comprises a plate-shaped calf rest pad (22)and a mounting (21) which is mounted on the patient chair by means of a jointarrangement (21b, 24). The joint arrangement (21b, 24) is designed so that thecalf rest pad (20) is movable between an inactive moved-away end position, inwhich the extent of the calf rest pad is substantially parallel to one side ofthe patient chair and the calf rest pad is positioned close to the patientchair, and a second active end position, where the calf rest pad is capable ofsupporting the patient's legs when extended, outwards away from the patientchair.
