First Claim
Patent Images
1. A helmet-mountable display unit comprising:
- an electronic display;
a connector to adjustably connect the display to a helmet, the connector including;
an attachment portion that fastens the connector to the helmet;
a first joint having a first axis of rotation to permit pitch rotation of the display; and
a second joint having a second axis of rotation to permit yaw rotation of the display, wherein the display is linearly movable along a direction of the second axis of rotation, the second joint and the attachment portion being two different components, and linear movement of the display along the direction of the second axis of rotation occurring independently of the attachment portion fastening the connector to the helmet.

Abstract
Helmet-mounted display unit arrangements provide improved adjustability, including pitch, yaw, and/or vertical translation adjustment. In some embodiments, adjustments to one parameter do not affect the adjustability of other parameters. The helmet-mounted display and associated mount may be arranged such that the helmet-mounted display fits behind a helmet-mounted visor and/or in front of glasses being worn by the user.

20. A helmet-mountable display unit comprising:
-
an electronic display; a connector to adjustably connect the display to a helmet, the connector including; an attachment portion to attach the connector to the helmet; a first joint comprising a revolute joint having a first axis of rotation to permit changes to a pitch orientation of the display; a second joint having a second axis of rotation to permit changes to a yaw orientation of the display; and a clamp that frictionally engages with the first joint and the second joint to prevent yaw rotation of the display about the second axis of rotation and pitch rotation of the display about the first axis of rotation when the clamp is engaged by a clamp actuator, wherein the clamp is engageable to lock the display in a first pitch orientation and in a second, different pitch orientation, wherein a position of the second axis of rotation of the second joint remains stationary as the pitch orientation of the display changes, and wherein when the display is connected to the helmet and the helmet is worn by the user, the display is configured to be visible to at least one of the wearer'"'"'s eyes. - View Dependent Claims (21, 22)

23. A helmet-mountable display unit comprising:
-
an electronic display; a connector to adjustably connect the display to a helmet, the connector including; an attachment portion having a fastener portion having first and second engagement surfaces, wherein the first engagement surface moves relative to the second engagement surface in a first direction from a first orientation to a second orientation to fasten the connector to the helmet; a first joint having a first axis of rotation to permit pitch rotation of the display; and a second joint having a second axis of rotation to permit yaw rotation of the display, wherein the display is linearly movable along a direction of the second axis of rotation in a linear sliding direction that is different from the first direction. - View Dependent Claims (24)
