Abstract
The invention relates to a pressure relief latch for aircraft, able to absorb vibrations and shocks without inopportune opening, as well as to adapt to dimensional stresses during its assembly. The latch includes: a console, a lever mounted on the console, and an opening effort exerted on a fulcrum of the lever causing an angular displacement of the fulcrum between a closing position and an opening position. The latch also includes a roller able to roll against a profile of the lever and connected to an elastic return device. The latch further being provided with means able to vary the angular displacement of the fulcrum of the lever according to the opening effort, with two different slopes according to an opening effort E1.
