Hydraulic lifting arm for assisting handicapped person to get out of bath comprises actuator containing piston and hollow rod exerting traction on flexible connections between actuator and application point

摘要

The lifting arm comprises a tubular hydraulic actuator (1) composed of a cylindrical tube (3) which exerts a traction on flexible tubular connections (6) interposed between the actuator and an application point (7). These connections enable hydraulic control at a distance from the actuator. The actuator comprises a piston (2), sliding in the cylindrical tube, having a hollow rod (17) at the end of which is an inner guide (5) integral with a distributor (4) outside the driving tube of the flexible connections.
