Abstract
A shift safety device for a manual transmission having a gear shift shaft that rotates to select shift gates and moves to shift gears. The device has a blocking element which, during selector motion towards a shift gate, is driven by the gear shift shaft, against a spring, from a starting position into a blocked position, in which the device blocks further selector motion of the gearshift shaft, and which, during subsequent shifting motion of the gearshift shaft, is released and returned back to the starting position, by the spring, thereby permitting further selector motion. A driver arm, disposed on the gear shift shaft, moves the blocking element tangential to the arc traversed during selector motion by the driver arm between the starting and blocking positions. The blocking element moves in the linear track traversed during shifting of the driver arm and is pretensioned toward the starting and center positions.
