Openable flap, in particular exhaust gas flap

摘要

The hinged lid (5) has a hinge (6) at the top of the rear wall (4) of the frame (1) for the hatch. The hinge may allow the hatch to swing open through an angle of up to 140 degrees. There is a catch (8) releasable by a cord (7) opposite the hinge. A first powerful gas spring (12) lifts the end (13) of a lever (10) near the catch. The other end (11) is hinged near the hinge for the lid. A second weak gas spring (15) is hinged (16) between the center of the lever and a hinge point (17) on the lid.
