Information handling system hinge and flexible cover

摘要

A portable information handling system has lid and main portions rotationally coupled to each other with a set of hinges having motion managed by rack and pinion gears. The rack translates motion between pinions by moving outward from the housing portions during rotation of the housing portions. A flexible cover over the rack stretches in response to movement of the rack to contain the hinges within the portable information handling system structure.
