New ergonomic workstation with assisted movement for hairdressers

Abstract

The new ergonomic workstation for hairdressers allows the hairdressers to operate comfortably while sitting, standing or with half-bent knees, avoiding potentially harmful positions for the musculoskeletal system. It has a bicycle saddle-type seat with adjustable height attached to a backrest with armrests, and a rotation element surrounding the base of the customer's seat, allowing the hairdresser to reach different work areas. It has means for regulating the height of the backrest assembly by a lifting system, such as a gas piston that is extended in its natural position, thus reducing the postural load of the hairdresser, which means is actuated when the hairdresser presses down on the backrest without using their hands. It has at least one rolling support that improves the stability of the structure. It is intended for the industrial sector dedicated to the construction of chairs and workstations.

1 . New ergonomic workstation with assisted movement for hairdressers characterised in that enabling adjustment of the hairdressing worker's workspace, both in its vertical dimension and in his horizontal reach, enabling the hairdresser to work sitting down, with bent knees or standing up; for this purpose it has a saddle-type seat ( 10 ) and a supporting backrest with armrests ( 11 ), both joined to a vertical section of a frame ( 4 ) the side elevation of which has a geometry comprising a near right angle and the horizontal part parallel to the floor of which is fixed at its free for and to a turning element ( 3 ) with an anchoring element ( 5 ) with a conventional torque between them; the turning element surrounds the base ( 2 ) of the client's chair ( 1 ) and is fixed by conventional means such as a screwed clamp joint; the length of the horizontal section of the frame can be changed according to the hairdresser's requirements by conventional means such as use of a telescopic tubular structure ( 6 ) of concentric rods; the height of the seat and backrest is adjusted by a conventional lift system ( 8 ) such as a gas piston located in the vertical part of the frame under the seat, which is in its natural extended position when its valve is not operated, the latter being activated when the hairdresser makes a slight movement to tilt the backrest, use of his hands therefore being unnecessary, this action ordering activation of the piston and the consequent descent of the seat/backrest assembly through an activation system ( 9 ) consisting of a set of levers; it has at least one caster wheel as a rolling support ( 7 ) located in the horizontal section of the frame ( 4 ).
