Gull-wing type side door for motor vehicle - is hinged to sloping portion instead of upright of door frame, and held open by gas-pressure spring at forward end

摘要

The vehicle door frame (3) has an upright portion (3a) to which conventionally a door is hinged, and a rearward-sloping portion (3b) which carries a hinge (4) with its axis of rotation (5) parallel to a sloping edge of the door (2) but outside the bodywork. A pneumatic spring (6) is coupled to the door at the leading end of its sill (7) and below the hinge. Rotation of the door about the hinge (8) frees the entire opening for access to interior seating. USE/ADVANTAGE - Esp. on private cars or utility vehicles. Mass-produced side doors are easily convertible into folding type.
