Description

Technical Field

[0001] This utility model relates to the field of seating technology, specifically a theater seat. Background Technology

[0002] Theater seating is designed specifically for large venues such as theaters, auditoriums, and conference rooms. Most theater seats consist of four parts: seat, backrest, armrests, and legs. The legs and armrests are integrated to form a sturdy armrest frame, typically made of steel and wood or steel and plastic. The seat and back cushions are usually made using a polyurethane cold-curing foaming process, with moderate density and thickness to ensure they do not deform over long-term use. The back and seat shells are mostly made of polypropylene multi-element material, manufactured using one-piece injection molding technology, making them sturdy and stable.

[0003] Existing theater seating is generally used in theaters or conference rooms where people need to sit for long periods of time. When sitting for long periods of time, the pressure on the user's legs and waist will gradually increase, making it easy to feel uncomfortable. At the same time, sitting for long periods of time will cause serious fatigue.

[0004] Therefore, those skilled in the art have provided a theater seat to address the problems mentioned in the background section. Utility Model Content

A servo motor 202 is fixedly connected to one side of the C-shaped plate 201. A drive shaft 203 is fixedly connected to the transmission end of the servo motor 202. A worm gear 204 is fixedly sleeved on the side surface of the drive shaft 203. A worm wheel 205 is meshed with the bottom of the worm gear 204. The support assembly 2 also includes a rotating shaft 206, a fixing plate 207, a leg support 208, and a mounting plate 209. The rotating shaft 206 is fixedly connected to one side of the worm wheel 205. A fixing plate 207 is fixedly sleeved on the side surface of the rotating shaft 206. A leg support 208 is fixedly connected to one side of the fixing plate 207. A mounting plate 209 is connected to one side of the rotating shaft 206.

[0025] Please refer to Figure 1 - Figure 5 This embodiment is based on the previous embodiment, but differs in that a connecting hole 9 is provided on the other side of the inner wall of the seat body 1. A connecting rod 10 is rotatably connected inside the connecting hole 9. An armrest 11 is fixedly connected to the other side of the connecting rod 10. A switch button 12 is fixedly connected to the top of the armrest 11. A limiting plate 13 is sleeved on the side surface of the connecting rod 10. A limiting hole 14 is provided inside the limiting plate 13. A telescopic rod 15 is provided on one side of the limiting plate 13. A return spring 16 is sleeved on the side surface of the telescopic rod 15. A fixing plate 17 is fixedly connected to the other side of the telescopic rod 15. An adjusting plate 18 is fixedly connected to the top of the fixing plate 17. On the other side of 7, a limiting rod 19 is fixedly connected. The limiting rod 19 is adapted to the limiting hole 14. A base 20 is provided at the bottom of the seat body 1. A protective shell 21 is fixedly connected to the top of the base 20. A synchronous motor 22 is fixedly connected to the bottom of the inner wall of the protective shell 21. A base 20 is provided at the bottom of the seat body 1. A protective shell 21 is fixedly connected to the top of the base 20. A synchronous motor 22 is fixedly connected to the bottom of the inner wall of the protective shell 21. A lead screw 23 is fixedly connected to the transmission end of the synchronous motor 22. A lifting tube 24 is slidably connected to the side surface of the lead screw 23. A connecting plate 25 is fixedly connected to one side of the seat body 1. The connecting plate 25 is fixedly connected to the lifting tube 24.

[0026] Further explanation is needed: the leg support 208 is driven by the servo motor 202 to adjust the angle. Users can easily adjust the position of the leg support according to their personal needs, effectively dispersing the pressure on the legs and waist when sitting for a long time, significantly improving the comfort of sitting posture. The flexibly adjustable angle of the leg support 208 allows users to find the most suitable sitting posture, thereby effectively reducing the fatigue caused by maintaining a fixed sitting posture for a long time and improving the efficiency and enjoyment of work or viewing activities.

[0027] The working principle of the above embodiment is as follows: First, the user can sit on the seat body 1 and press the switch button 12. The servo motor 202 starts and drives the worm gear 204 to rotate through the transmission shaft 203. The rotation of the worm gear 204 drives the worm wheel 205 to rotate. The worm wheel 205 drives the fixing plate 207 and the leg support 208 to adjust their angles through the rotating shaft 206. The user can adjust the angle of the leg support 208 to support their legs according to their own needs, thereby finding the most comfortable sitting posture.

[0028] Next, when the handrail 11 needs to be rotated to any angle, the user can push the adjustment plate 18, the return spring 16 and the telescopic rod 15 will be compressed, causing the limit rod 19 to exit from the limit hole 14. Then, the handrail 11 is rotated. When the handrail 11 is rotated, the connecting rod 10 rotates accordingly, and the limit plate 13 also rotates. When the handrail 11 is rotated to the required angle, the adjustment plate 18 is released. Under the restoring ability of the return spring 16, the limit rod 19 is reinserted into the new limit hole 14.

[0029] Finally, when the height of the seat body 1 needs to be adjusted, the synchronous motor 22 starts and drives the lead screw 23 to rotate through the transmission end. The rotation of the lead screw 23 causes the lifting tube 24 to slide on the lead screw 23, thereby changing the height of the lifting tube 24. Since the connecting plate 25 is fixedly connected to the lifting tube 24 and the connecting plate 25 is also fixedly connected to one side of the seat body 1, the change in the height of the lifting tube 24 will cause the height of the seat body 1 to change.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
