Abstract

A strap system for a head-mounted display system includes a rigid bar, semi-rigid segment, and rigid segment. The rigid bar includes a lateral slot and a vertical slot. The rigid segment includes a first end to fixedly couple to the semi-rigid segment and a second end opposite to the first end. The second end of the rigid segment inserts into the lateral slot from the first end of the rigid bar. The strap system further includes one or more compression springs coupled to the rigid segment, and a shuttle to press against the one or more compressions spring so as to slide along the lateral dimension. The strap system also includes an adjustment strap fixedly coupled to the shuttle and extending beyond the second end of the rigid segment and through the vertical slot on the rigid bar to adjustably couple to the outer surface of the rigid bar.

First claim

What is claimed is:

1. A strap system for a head-mounted display system, the strap system comprising:
a rigid bar including a lateral slot and a vertical slot, the lateral slot opening at a first end of the rigid bar and extending within the rigid bar in a lateral dimension, the vertical slot situated on an outer surface of the rigid bar;
a semi-rigid segment;
a rigid segment including a first end to fixedly couple to the semi-rigid segment and a second end opposite to the first end, the second end of the rigid segment inserted into the lateral slot from the first end of the rigid bar;
one or more compression springs coupled to the rigid segment;
a shuttle to press against the one or more compression springs so as to slide along the lateral dimension; and
an adjustment strap fixedly coupled to the shuttle and extending beyond the second end of the rigid segment and through the vertical slot on the rigid bar, the adjustment strap including a first coupling structure to adjustably couple to the outer surface of the rigid bar.

2. The strap system of claim 1 , wherein the rigid bar includes a second end opposite to the first end of the rigid bar, the second end being closed.

3. The strap system of claim 1 , wherein the rigid bar includes a second coupling structure on an inner surface to couple to a head-mounted display.

4. The strap system of claim 3 , wherein the second coupling structure includes a cylinder with a hollow center to receive a protrusion from the head-mounted display.

5. The strap system of claim 1 , wherein the rigid segment includes one or more grooves on an inner surface of the rigid segment, the one or more grooves to accommodate the one or more compression springs.

6. The strap system of claim 5 , further comprising one or more rails surrounded by the one or more compression springs, each rail of the one or more rails including two ends connected to the inner surface of the rigid segment, and each rail of the one or more rails situated within a groove of the one or more grooves.

7. The strap system of claim 6 , wherein the shuttle includes one or more openings, each rail inserted into a corresponding opening of the shuttle to slidably mount the shuttle on the one or more rails, the shuttle to compress the one or more compression springs along the lateral dimension when sliding.

8. The strap system of claim 1 , wherein the adjustment strap includes:
a first portion accommodated by the rigid segment and;
a second portion wider than the first portion, the second portion including the first coupling structure to adjustably couple to the outer surface of the rigid bar.

9. The strap system of claim 8 , wherein:
the outer surface of the rigid bar includes a first layer of a hook-and-loop fastener; and
the second portion of the adjustment strap couples to the outer surface of the rigid bar using a second layer of the hook-and-loop fastener.

10. The strap system of claim 1 , wherein the adjustment strap is screwed to the shuttle.

11. The strap system of claim 1 , further comprising a connecting member coupled to the semi-rigid segment and rigidly connected to the rigid segment.

12. The strap system of claim 11 , wherein the rigid segment includes one or more screw holes on an inner surface of the rigid segment, and the connecting member is fixedly coupled to the one or more screw holes on the rigid segment.

13. The strap system of claim 11 , wherein the connecting member is coupled to a protrusion of the semi-rigid segment extending toward the rigid segment.

14. The strap system of claim 11 , wherein the shuttle is situated between the connecting member and the one or more compression springs.

15. The strap system of claim 1 , wherein the semi-rigid segment conforms to a portion of the user's head, the semi-rigid segment including a first arc portion to extend from above a user's first ear to below the user's occipital lobe and a second arc portion to extend from above the user's second ear to below the user's occipital lobe.

16. The strap system of claim 15 , further comprising:
a rigid piece, coupled to the semi-rigid segment to rest against the back of the user's head.

17. The strap system of claim 16 , further comprising a top strap having a first end connected to the semi-rigid segment and a second end to adjustably fit a head-mounted display on the user's head, the top strap to conform to the top of the user's head from the rigid piece to the head-mounted display.
