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.

Background

Virtual-reality head-mounted displays have wide applications in various fields, including engineering design, medical surgery practice, military simulated practice, and video gaming. For example, a user wears a virtual-reality head-mounted display integrated with audio headphones while playing video games so that the user can have an interactive experience in an immersive virtual environment.

However, it may be difficult for a user to properly adjust and comfortably wear the head-mounted displays and the integrated audio systems using existing technology, which may negatively affect the user’s experience.

Summary

The embodiments of the present disclosure provide a strap system for a head-mounted display system. In accordance with some embodiments, the strap system includes a rigid bar with a lateral slot and a vertical slot. The lateral slot opens at a first end of the rigid bar and extends within the rigid bar in a lateral dimension. The vertical slot is situated on an outer surface of the rigid bar. The strap system also includes a semi-rigid segment and a rigid segment. 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. The adjustment strap includes a first coupling structure to adjustably couple to the outer surface of the rigid bar.

Various advantages of the present application are apparent in light of the descriptions below.
