ABSTRACT:
A gear-shift device includes a pivotably mounted selector lever for actuation by the driver, a pivotably mounted actuating lever linked to the selector lever and a transmission member articulated to the actuating lever and which in use acts upon an automatic gear box transmission. The selector lever is pivotably mounted at a first pivot axis through a shift device housing so as to be movable in first and second gear shift gates connected by transverse gate. The actuating lever is supported at the housing for pivotal movement about a second pivot axis spaced from the first pivot axis. A disengageable coupling connects the actuating lever and the selector lever when the selector lever is in the first shifting gate and disconnects the selector lever and actuating lever when the selector lever is moved to the second shifting gate. The coupling connection is disposed spaced from the first and second pivot axes and is configured to provide pivotal movement of the actuating lever about the second pivot axis in response to pivotal movement of the selector lever about the first pivot axis, while accommodating relative sliding movement of the levers with respect to one another at the coupling connection.
