Abstract: In the driver's compartment of a motor vehicle, a dash console containing instruments and controls is hinged along a bottom edge to dash structure of the compartment. A steering wheel column is pivotally mounted by a pivot joint to the floor of the compartment and is clamped by an openable clamp to the dash structure into an upright operating position. When the clamp is opened, the steering column may be swung downwardly about the pivot point until the steering wheel rests upon a driver's seat. Then the dash console may be swung from its normally upright operating position downwardly to an access-providing position against the reclining steering column thereby enabling maintenance personnel convenient access to the backside of the dash console.

Abstract: A towbar receiving assembly for large trucks, particularly useful for cab-over-engine trucks and other trucks wherein a radiator assembly is positioned directly above a generally flat front bumper, blocking access from above to the space behind the bumper. A towbar pin is inserted from below upwardly into a tow eye box directly behind an opening in the bumper, through which a towbar eye is received and is engaged by the pin. Projecting tabs on the pin and complementarily-shaped slots in a vertical opening associated with the tow eye box provide for receipt of the pin in a particular rotational orientation, and risers or boss areas around the slots provide for the retention of the pin in a locked-in position following its insertion and rotation from the boss areas.
