Pivotal hood arrangement, especially in motor vehicles

A pivotal hood-like structure for covering a separate aggregate space underneath an engine hood for the accommodation of a windshield wiper installation, said aggregate space being arranged between the engine space and passenger space of a motor vehicle within the area underneath the windshield thereof, said hood-like structure comprising:

• a hood normally covering said separate aggregate space when in a closed position;
• means for mounting said hood so as to be pivotal about a pivot axis into a first open position, whereby said windshield wiper installation may be operated, and into a second open position, whereby increased access to said separate aggregate space may be afforded for purposes of maintenance and repair;
• a reciprocable piston means for displacing said hood between the closed and first open positions;
• means fixedly attached to said hood for enabling the reciprocating motion of the reciprocable piston means to be converted into pivotal motion, said enabling means being adapted to be in operable engagement with said piston means when said hood is in its closed and first open positions;
• and
• means positioned between said vehicle and said hood, for biasing said hood toward said closed position and for biasing said enabling means into operable engagement with said piston means when said hood is in its closed and first open positions.
