Abstract
The present document describes a link member for providing an interface between an actuator and a seat base. The link member has a translational degree of freedom and at least two rotational degrees of freedom. The link member comprises: a joint member having a spherical surface, the joint member for attachment to one of the actuator and the seat base; a housing for attachment to the other one of the actuator and the seat base; and a slider mounted on the spherical surface and within the housing. The slider is free to move in a direction of a translational plane within the housing thereby providing the translational degree of freedom. Furthermore, the slider is free to slide on the spherical surface and to pivot about a first axis and a second axis thereby providing the at least two rotational degrees of freedom.
