Abstract
A parking brake assembly for a vehicle has a mounting bracket, a handle assembly and a clutching mechanism. The mounting bracket has a stop. The handle assembly is pivotally mounted on the mounting bracket for rotation about a first axis. The handle is moveable between a brake applied position and a brake release position. The handle has an actuator. A cam is pivotally mounted on the handle about a second axis offset from the first axis. The cam has a cam surface which varies radially from the second axis. The cam is biased to engage the stop. A clutch spring frictionally engages the cam and is operably connected to the actuator. Movement of the actuator in response to manual manipulation responsively moves the clutch spring to decrease the frictional engagement, thereby enabling the cam to engage with the stop. In response to releasing the actuator, the clutch spring moves to increase frictional engagement with the cam thereby retaining the cam in a position to engage the stop and prop the handle in a braking position.
