US Patent 11016540 Bi-stable synchronized dual axle hinge

A portable information handling system housing rotationally couples first and second housing portions with a hinge assembly having first and second breakaway brackets that define an adjacent position of the first and second housing portions relative to each other and a spread position. The first and second breakaway brackets expand the spacing between the first and second housing portions in the event that the housing portions close over an object disposed between them. The breakaway brackets bias to the adjacent position with a biasing device and a retainer that maintains the adjacent position unless a predetermined force is applied through the hinge assembly at the breakaway brackets.
