Claim Text:
1. A manually operated lever device for actuating a parking brake of a motor-vehicle, comprising: a supporting bracket, connected to a structure of the motor vehicle; and a lever structure, having: so that said lever structure is movable between a completely lowered position and a completely raised position with respect to said supporting bracket, wherein a tiltable mounting of the base portion on the supporting bracket comprises: a first transverse axis and a second transverse axis, which are defined at predetermined positions with respect to the supporting bracket; a third transverse axis and a fourth transverse axis, which extend through said base portion of the lever structure in positions arranged spaced apart from one another; said third transverse axis and said fourth transverse axis being constrained to move along respective paths, about said first transverse axis and about said second transverse axis; the lever structure being operatively connected to a transmission for actuating the parking brake of the motor vehicle, said second transverse axis located in front of said first transverse axis, with reference to a direction of forward advancement of the motor-vehicle; when the lever structure is in the completely lowered position, said third transverse axis and said fourth transverse axis each located in a position lower than that of the first transverse axis and the second transverse axis, respectively; and in said completely lowered position, two planes containing the first and third transverse axes and the second and fourth transverse axes, respectively, intersecting along an axis of instantaneous rotation of the lever structure, which is located above said first and second transverse axes, and wherein, when the lever structure moves from the completely lowered position to the completely raised position, the lever arm and the handgrip directly connected to the end of the lever arm displace upwardly along a path corresponding to a portion of an ellipse, while said axis of instantaneous rotation of the lever structure moves downwards, following an elliptical path; wherein the tiltable mounting of the base portion on the supporting bracket comprises: a first connection arm, having a first end and a second end, said first end being pivotally mounted on the supporting bracket about said first transverse axis, and said second end being pivotally connected to said base portion about said third transverse axis; and a second connection arm, having a first end and a second end, the first end of the second connection arm being pivotally mounted to the supporting bracket about said second transverse axis, and the second end of the second connection arm being pivotally connected to said base portion about said fourth transverse axis.
