Patent ID: 8502433

Claim:
A grip member comprising means for generating a haptic feed-back, wherein said means comprise a plurality of haptic feed-back generator modules distributed along said grip member, and means for controlling activation of said modules according to a pre-set sequence in such a way as to generated a pre-set haptic signal on said grip member, wherein the pre-set haptic signal is of a type travelling along the grip member, in such a way as to transmit a sensation of direction, wherein each module has a body of a substantially cylindrical shape with two opposite faces set on which is a piezoelectric element constrained in at least one point to the body so that the mechanical vibration of the piezoelectric element is transmitted to the module itself, and wherein the piezoelectric element is equipped with a striking member co-operating with the body so that a pulsed electrical supply of the piezoelectric element causes an alternating percussion of the striking member against the body of the module such as to impart a vibratory effect upon said body.
