Augmented reality system eye relief adjustment mechanism
First Claim
1. A head mounted display (HMD) to be worn by a user, comprising:
- an adjustable crown band;
a crown band circumference adjusting mechanism coupled to the adjustable crown band and configured to adjust a circumference of the crown band to releasably secure the crown band to the crown of the user;
an armature including a left arm and a right arm, each of the left arm and the right arm mounted at a respective proximal end to corresponding left and right attachment structures on the HMD;
a display mounted at left and right sides to respective distal ends of the left and right arms; and
an eye relief distance adjustment mechanism comprising respective sliding structures on the crown band that slidingly receive the left arm and the right arm such that the left arm and the right arm can slide in a timed manner to move the display toward and away from the crown band along a substantially linear path when a pushing or pulling force is applied to the display by the user, to thereby adjust an eye relief distance from the display to an eye of the user when the crown band is fitted on the crown of the user.

2. A head mounted display (HMD) to be worn by a user, comprising:
-
an adjustable crown band; a crown band circumference adjusting mechanism coupled to the adjustable crown band and configured to adjust a circumference of the crown band to releasably secure the crown band to the crown of the user, the crown band circumference adjusting mechanism comprising; a first housing mounted at a posterior end of the HMD, the first housing including a first knob and a first pinion rotatably coupled thereto; and left and right crown racks mounted at posterior ends of the adjustable crown band, the left and right crown racks passing through the first housing and engaged to the first pinion wherein rotating the first pinion via the first knob adjusts a length of the left and right crown racks passing through the first housing to adjust the circumference of the crown band; an armature including a left arm and a right arm, each of the left arm and the right arm mounted at a respective proximal end to corresponding left and right attachment structures on the HMD; a display mounted at left and right sides to respective distal ends of the left and right arms; and an eye relief distance adjustment mechanism configured to move the left and right arms in a timed manner toward and away from the crown band along a substantially linear path when a pushing or pulling force is applied to the display by the user, to thereby adjust an eye relief distance from the display to an eye of the user when the crown band is fitted on the crown of the user. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A head mounted display (HMD) to be worn by a user, comprising:
-
an armature including a left arm and a right arm, each of the left arm and the right arm mounted at a respective proximal end to corresponding left and right attachment structures on the HMD; a display mounted at left and right sides to respective distal ends of the left and right arms; and an eye relief distance adjustment mechanism configured to move the left and right arms in a timed manner toward and away from an eye of the user along a substantially linear path when a pushing or pulling force is applied to the display by the user, to thereby adjust an eye relief distance from the display to the eye of the user, the eye relief distance adjustment mechanism comprising respective linear motion actuators at the left and right attachment structures that slidingly receive the left arm and the right arm such that the left arm and the right arm can be linearly slid in the timed manner to move the display toward and away from the crown band along the substantially linear path.
