Abstract
The rotation-retarding device includes a first element and a second element having a rotary motion to be retarded relative to each other. The first element includes a block of flexible material (106), the second element (107) is able to locally deform the block of flexible material (106) throughout the rotary motion in order to retard this motion, and anti-adherence means are provided at the interface of the two elements. The block of flexible material (106) may also have a dimensional variation able to permit progressive retarding of the rotary motion.
