Abstract: A lever device for actuating the parking brake of a motor-vehicle includes a lever structure with a base portion tiltably mounted on a supporting bracket. The mounting includes a first transverse axis, a second transverse axis, a third transverse axis and a fourth transverse axis. When the lever structure is in its completely lowered position, the third and fourth transverse axes are each lower than that of the first and second transverse axes, respectively. In the lowered position, two theoretical planes containing the first and third transverse axes and the second and fourth transverse axes, respectively, intersect along a theoretical axis of instantaneous rotation of the lever structure, which is located above said first and second transverse axes. When the lever structure moves from its completely lowered position to its completely raised position, the lever arm and its end handgrip displace according to a substantially elliptical, and substantially vertically oriented, path, respectively, while the axis of instantaneous rotation of the lever structure moves downwards, following a substantially elliptical path.
