Abstract

A strap system for a head-mounted display system includes a rigid bar having an opening at a first end and a vertical slot situated on an outer surface of the rigid bar. The opening extends within the rigid bar in a lateral dimension. The strap system also includes a rigid segment with an end inserted into the opening of the rigid bar in the lateral dimension, 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 end of the rigid segment and through the vertical slot on the rigid bar.

Claims

1. A strap system for a head-mounted display system, the strap system comprising:

a rigid bar having an opening at a first end and a vertical slot situated on an outer surface of the rigid bar, wherein the opening extends within the rigid bar in a lateral dimension;

a rigid segment including an end inserted into the opening of the rigid bar in the lateral dimension;

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 end of the rigid segment and through the vertical slot on 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 an inner surface of the rigid bar is coupleable to a head-mounted display.

4. The strap system of claim 3, wherein the rigid bar includes, on the inner surface, 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, 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, wherein the end of the rigid segment inserted into the opening of the rigid bar is a first end of the rigid segment, the strap system further comprising:

a semi-rigid segment; and

a connecting member coupled to the semi-rigid segment and rigidly connected to a second end of the rigid segment, wherein the second end of the rigid segment is opposite to the first end of 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 opening at the first end of the rigid bar is an opening of a lateral slot extending within the rigid bar in a lateral dimension.
