Patent ID: 7637179

Claim:
An actuating mechanism for a parking brake, comprising: a bearing block; a handbrake lever positioned pivoting on the bearing block; a brake setting device including a locking segment secured to the bearing block and a movably positioned locking pawl, the locking pawl having: an edge segment facing the locking segment, and an indentation in the edge segment, the indentation having discreet surfaces; an actuating linkage positioned inside the handbrake lever and including a web to connect the actuating linkage to the locking pawl, the web contoured to engage the indentation in the edge segment of the locking pawl; a spring loaded push button movable to activate the actuating linkage; and a catch spring arranged to secure the locking pawl in an engaged position on the locking segment; wherein during actuation of the actuating linkage by the push button, the web engages the discreet surfaces in the indentation in the edge segment of the locking pawl and exerts a force counter to the force of the catch spring to separate the locking pawl from the locking segment, and during pivoting of the handbrake lever, contact between the locking pawl and the locking segment disengages the web from the discreet surfaces in the indentation in the edge segment of the locking pawl.
