Abstract

Abstract A hood door assembly including a first door which swings about a generally horizontally disposed axis and a second door which swings about a generally vertical axis for providing access to an engine compartment for servicing of an engine. A rod is provided for holding the first door both in its open and closed positions. One end of the rod is pivotally attached to the hood while a free end of the rod is engageable within a slot in a retainer plate when the first door is closed. The rod includes a bent handle portion adjacent its free end which is rotated for engaging or releasing the free end of the rod within the retainer plate slot when the first door is closed. Further, when the first door is swung open about its generally horizontal axis, the free end of the rod is inserted through an opening in a bracket on the first door such that the bent handle portion engages the bracket for supporting the first door in an open position. When the first door is closed, the rod is swung into sliding engagement with the retainer plate slot such that a mid-portion of the rod is deflected against the first door bracket thereby resulting in spring tension against the bracket for holding the first door closed.
