Abstract:
1. A rotation-retarding device, comprising: a support; a first element being attached to said support; and a second element being rotatably attached, at a connecting portion thereof, to said support to be moveable, along a path, relative to said first element which is adapted to retard a rotary motion of said second element along said path; wherein said second element further includes a projection other than said connecting portion, said projection being stationary relative to said connecting portion during the entire rotary motion of said second element along said path; said first element includes a flexible body which is in physical contact with and deformed by the projection of said second element when said second element is on said path; a degree of deformation of said body caused by said projection varies along said path so that said rotary motion is progressively retarded by said body; and the connecting portion of said second element comprises two legs, and said body and said projection are disposed between said legs.
