Abstract: The invention provides a biasing device for biasing a movable first structure to a position relative to a second structure, said biasing device includes aconnection mechanism for interconnecting said first and second structures, said connection mechanism including at least one motion reducing mechanism; andextensible and/or compressible biasing means for providing a biasing force;the biasing means is connected between said first or second structure and said motion reducing mechanism so that the length of extension or compression of said biasing means is less than the movement of said first structure relative to said second structure.
