Abstract

A hydraulically damped hinge comprising: a first hinge member (5) having a cylinder barrel (17) forming a first knuckle of the hinge; a second hinge member (6) pivotably mounted on the first hinge member (5) and comprising a second and third knuckle (20, 21) which are situated at opposing ends (22, 23) of the cylinder barrel (17); a torsion spring (79) within a double-wall portion of the cylinder barrel (17) and having a first extremity connected to the first hinge member (5) and a second extremity (81); a dashpot within the cylinder barrel (17); and a rotatable tensioning element (83) within the double-wall portion of the cylinder barrel (17) and fixed to the second knuckle (20) and to the second extremity (81) of the torsion spring (79). The rotatable tensioning clement (83) allows tensioning the torsion spring (79) during assembly of the hinge. Placement of the rotatable tensioning element (83) avoids needing to provide a recess in the second knuckle (20) thereby improving the overall strength of the second hinge member (6).
