Description

Technical Field

[0001] This utility model relates to the field of cinema dynamic seating technology, specifically to a double-fork arm lifting and flying cinema seat with multiple degrees of freedom of backward tilting motion. Background Technology

[0002] Virtual reality (VR) technology is a novel and practical technology that emerged in the 20th century. It encompasses computer science, electronic information, and simulation technology, and its basic implementation involves computer-simulated virtual environments to create a sense of immersion. Motion cinema evolved from traditional 3D cinemas. Compared to other types of cinemas, and compared to the more realistic visual experience offered by 3D cinemas, motion cinemas combine the film's plot with a dynamic platform to provide viewers with a more lifelike viewing experience.

[0003] Although the existing methods of achieving motion in seats mainly involve using a motor to drive a rocker arm to make the seat swing left and right and back and forward, and a vibrator to make the seat vibrate, this method of motion has the disadvantage of small range of motion and limited freedom of motion. As a result, when people watch movies, they cannot have a better sensory experience with the movie scenes, which more or less affects the effect of watching 3D movies. Summary of the Invention
