Abstract: A steering assembly has a yoke and an axially compliant intermediate shaft having an elastomeric coupling fitted concentrically to the yoke for rotation about an axis. Preferably, a rigid sleeve of the shaft has a cylindrical portion that fixes concentrically to an end portion of a shaft element that extends longitudinally along the axis. Two diametrically opposite tabs of the sleeve project radially outward from the cylindrical portion. A resiliently flexible isolator is preferably molded to the sleeve and circumferentially covers the tabs and the cylindrical portion. The isolator preferably has two diametrically opposite ears located circumferentially between two diametrically opposite cover segments that substantially cover the tabs. The tabs generally prevent rotation of the shaft with respect to the yoke in case of isolator failure due to the excessive torque. Each ear preferably has a lobe that projects axially beyond the sleeve for enhancing axial compliancy of the intermediate shaft.

Abstract: A manual transmission and ignition interlock is provided for a vehicle having a manual transmission operated by a shift lever. A solenoid is movable between positions blocking and unblocking movement of the vehicle ignition to OFF. A latch bar carried by the shift lever is biased to a latched position and can be moved to unlatched position by a pull-up ring on the shift lever. The latch bar is cammed downward against the spring bias out of latched position when it is extended through a slot in a latch retainer when the shift lever is moved to REVERSE, and then snaps up to latch the shift lever. Another solenoid has a plunger which extends to underlie the latch bar and trap it, thus locking the latched shift lever in REVERSE. In one embodiment, bi-stable solenoids are controlled by a controller that is provided with high and low current inputs from branch circuits that include control switches operated by ignition position.
