Abstract: A rotary recline mechanism for allowing reclining movement of a first part relative to a second part, the mechanism comprising: a first gear mechanism comprising first and second gear rings having first and second sets of teeth that engage to lock the first and second parts relative to each other and disengage on operation of an actuator to allow relative movement of the first and second parts by application of a force on one of the parts in a first direction, and a second override gear mechanism to allow relative movement of the first and second parts by application of a force in a second direction while the first and second sets of teeth are engaged.

Abstract: The disclosure relates to valve assemblies having a valve body including a first port, a second port and a fluid passageway extending therebetween. A valve member, having a through port, is arranged in the fluid passageway and is moveable between an open and closed positions. A sealing arrangement is arranged between the first port and the valve member and includes a sealing member arranged to seal against the valve member such that fluid cannot flow around an outer surface of the valve member. The sealing arrangement includes a sleeve arranged in the fluid passageway between the first port and the valve member. A deformable, incompressible, medium is contained around the sleeve and arranged such that, in use, a fluid within the sleeve exerts an outward pressure on the sleeve causing the sleeve to deform and act on the medium to push the sealing member against the valve member.
