Abstract:
A park-lock assembly (12) for unlocking and locking a key in an ignition switch (112) when a transmission is in a park and non-park position respectively, said assembly (12) comprising:a base (16);a gate (18) supported by said base (16) and having a park stepped region (22) which corresponds to the transmission being in the park position and a plurality of non-park stepped regions (24, 26, 28);a shift lever (30) movably supported by said base (16) and having a transversely extending pawl (34) movable between said stepped regions (24, 26, 28) when said shift lever (30) is moved;a conduit (58) having a first end (60) supported by said base (16) and a second end (102) for connection to the ignition switch (112), a core element (62) movably supported by said conduit (58) and having opposing ends (64, 104) for transmitting motion between said first (60) and second (102) ends of said conduit (58); andsaid assembly (12) being characterized by including a follower (50) attached to one of said opposing ends (64, 104) at said first end (60) and supported by said base (16) adjacent to said park stepped region (22) for rectilinear movement along an axis (A) to be moved to an unlocked position (X) in response to said pawl (34) being moved to said park stepped region (22) for unlocking the key in the ignition switch (112) and to be moved to a locked position (Y) in response to said pawl (34) being moved to one of said non-park stepped regions (24, 26, 28) for locking the key in the ignition switch (112), a housing (46) supported by said base (16) and defining said axis (A), said follower (50) at least partially disposed within said housing (46) for rectilinear movement along said axis (A).
