You must experience it in one state. Therefore, the harness used at this time is not only designed for the safety of the user, but in addition, in the case of simulations such as extreme fantasy, the operation of the platform (e.g., heave, roll, pitch, yaw. In order to maximize the sensory effect due to (yaw) motion), it is also designed to change the user's motion or position in various ways.

Through the present invention, it is intended to propose a harness having a structure for user safety while maximizing the sensory effect by being used in a platform or simulator for virtual reality or physical experience, in particular, for experiencing extreme fantasy worlds.

As a means to solve the above problems, a harness having a structure for effectively realizing the physical pressure due to water pressure in water has been developed for the realistic effect of virtual reality experience. In addition, a structure for making the movement of the body as similar to the actual situation as possible during operation of the simulator such as rotation, elevation, and tilt, and a harness having a structure for securing the safety of the wearer have been developed.

The configuration and operation of the present invention will become more apparent through specific embodiments described later together with the drawings.

According to the present invention, it is used in a virtual reality simulator to realize the effect of sensation of body pressure due to pressure during virtual reality experience, and the body can move as close to the actual situation as possible when the simulator is rotated, lifted, or tilted. Furthermore, it is possible to secure the wearer's safety against extreme simulator operation.
