One example provides an HMD device comprising a wearable support configured to be worn on a head of a user. The HMD device further comprises a head-up display mounted to the wearable support by a hinge assembly. The hinge assembly comprises a mounting component connected to the wearable support, and a bar connected to the mounting component at a first pivot. The bar is further connected to the head-up display at a second pivot. ## Claims ### Claim 1 A head-mounted display device, comprising: a wearable support configured to be worn on a head of a user; and a head-up display mounted to the wearable support by a hinge assembly, the hinge assembly comprising: a mounting component connected to the wearable support, and a bar connected to the mounting component at a first pivot and connected to the head-up display at a second pivot. ### Claim 2 (depends on 1) The head-mounted display device of claim 1, wherein one or more of the first pivot and the second pivot comprises a corresponding variable resistance mechanism that has less resistance through a transition point than other locations along one or more of a first path of travel of the head-up display and a second path of travel of the head-up display, the first path of travel being from a deployed position to a stowed position, and the second path of travel being from the stowed position to the deployed position. ### Claim 3 (depends on 2) The head-mounted display device of claim 2, wherein the first path of travel has a different resistance profile than the second path of travel. ### Claim 4 (depends on 2) The head-mounted display device of claim 2, wherein the variable resistance mechanism comprises a corresponding friction collar configured to generate a portion of a variable torque resistance. ### Claim 5 (depends on 2) The head-mounted display device of claim 2, wherein the variable resistance mechanism comprises a corresponding cam mechanism configured to generate a portion of a variable torque resistance. ### Claim 6 (depends on 2) The head-mounted display device of claim 2, wherein the variable resistance mechanism of the first pivot comprises a torsion spring configured to generate a portion of a variable torque resistance. ### Claim 7 (depends on 6) The head-mounted display device of claim 6, wherein the torsion spring is configured to bias movement of the first pivot opposite of gravity. ### Claim 8 (depends on 1) The head-mounted display device of claim 1, further comprising an adjustable stopper that allows a position of a hard-stop on the first pivot to be adjusted. ### Claim 9 (depends on 1) The head-mounted display device of claim 1, wherein the hinge assembly further comprises an adjustment mechanism that allows a position of the first pivot relative to the mounting component to be adjusted. ### Claim 10 A head-mounted display device, comprising: a wearable support configured to be worn on a head of a user; and a head-up display mounted to the wearable support by a hinge assembly, the hinge assembly comprising: a mounting component connected to the wearable support, a first bar connected to the mounting component at a first pivot, and a second bar attached to the first bar at a second pivot and attached to the head-up display. ### Claim 11 (depends on 10) The head-mounted display device of claim 10, wherein one or more of the first pivot and the second pivot comprises a variable torque resistance. ### Claim 12 (depends on 11) The head-mounted display device of claim 11, wherein the one or more of the first pivot and the second pivot comprises a corresponding one or more of a friction collar, cam mechanism, or a torsion spring configured to generate at least a portion of the variable torque resistance. ### Claim 13 (depends on 10) The head-mounted display device of claim 10, further comprising an adjustable stopper that allows a position of a hard-stop on the first pivot to be adjusted. ### Claim 14 (depends on 10) The head-mounted display device of claim 10, wherein one or more of the first pivot and the second pivot comprises one or more detents. ### Claim 15 (depends on 10) The head-mounted display device of claim 10, wherein the hinge assembly further comprises an adjustment mechanism that allows a position of the first pivot relative to the mounting component to be adjusted. ### Claim 16 A head-mounted display device, comprising: a wearable support configured to be worn on a head of a user; and a head-up display mounted to the wearable support by a hinge assembly, the hinge assembly comprising: a mounting component connected to the wearable support, a bar connected to the mounting component at a pivot and connected to the head-up display, a first adjustment mechanism that allows a position of the pivot relative to the mounting component to be adjusted; and a second adjustment mechanism that allows a position of the head-up display relative to the bar to be adjusted. ### Claim 17 (depends on 16) The head-mounted display device of claim 16, wherein the pivot comprises a tilt mechanism that allows movement between a first deployed position and a second deployed position of the head-up display. ### Claim 18 (depends on 17) The head-mounted display device of claim 17, wherein the pivot comprises one or more hard-stops to restrict angular movement of the pivot, and wherein an angular position of the one or more hard-stops relative to a rotational axis of the pivot is adjustable. ### Claim 19 (depends on 18) The head-mounted display device of claim 18, wherein the tilt mechanism comprises an eccentric pin and a control mechanism connected to the eccentric pin, the control mechanism comprising a frictional torque. ### Claim 20 (depends on 16) The head-mounted display device of claim 16, wherein one or more of the first adjustment mechanism and the second adjustment mechanism comprises interlocking features to restrict movement of the corresponding mechanism when engaged.
