improvement to devices inhibitors of graft inadvertent reverse external commands, for speed changes of vehicles.

摘要

the device includes a latch (11) associated with the fixed structure of joint of the lever.the latch (11) supported by a cannotto (12) movable axially in relation to the lever (10).is moveable to overcome the arrest inhibitor (21) and to allow the graft of the reverse and the lever switch (10) is movable in at least three floors of graft (p1 - p2 (p3).according to the invention, in order to improve the maneuverability of the lever switch (10).the arrest inhibitor (21) is bound girevolmente to the fixed structure (22) and is subjected to the action of an elastic means (23) which generates a torque tending to remove the collar (21) dthe rate of the trajectory covered by the latch (11) during the operation of the lever (10) in the first and second floor of graft (p1 - p2) (fig. 2).
