First Claim
Patent Images
1. An information handling system comprising:
- a chassis;
processing components disposed in the chassis and operable to process information;
a lid;
a display disposed in the lid and interfaced with the processing components, the display operable to present the information as visual images;
first and second hinges rotationally coupling the chassis and lid, each hinge having first and second axles;
a first friction member associated with the first hinge; and
a second friction member associated with the second hinge;
wherein the first and second friction members change torque at the first and second axles based upon an angle of rotation of the chassis relative to the lid to create a predetermined rotational behavior of the chassis relative to the lid.

Abstract
An information handling system hinge assembly simulates synchronous and other types of motions by applying friction varied based upon dual-axis hinge rotational position to generate differential torque at an information handling system chassis and lid portion. A connecting device maintains first and second hinges in position relative to each other during rotation of the chassis and lid portions, such as through 360 degrees of rotation between closed and tablet positions.

9. A method for rotating an information handling system lid portion relative to a chassis portion, the method comprising:
-
coupling first and second hinges to the lid portion and the chassis portion, each hinge providing rotation about first and second axles disposed along first and second axes; applying friction to the first and second axles with friction members, the friction resisting rotation of the first and second axles, the friction varying based upon the rotational position of the chassis and lid in order to create a predetermined rotational behavior. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A hinge assembly comprising:
-
attachment devices operable to couple the hinge assembly between an information handling system chassis portion and lid portion; first and second hinges coupled to the attachment devices, each of the first and second hinges having first and second axles; plural friction members, at least one of the plural friction members applying friction at each the first and second axles of each hinge, the friction varying based upon a rotational position and a direction of rotation of each of the first and second axles of each hinge so that the first and second hinges provide a predetermined rotational behavior of the chassis portion relative to the lid portion. - View Dependent Claims (18, 19, 20)
