Description

Technical Field

[0001] This utility model relates to the technical field of chairs specifically designed for special purposes, and particularly to an adjustable wraparound seat. Background Technology

[0002] As we all know, a chair is a type of seating that includes a seat and a backrest. To improve comfort, most chairs are also equipped with armrests.

[0003] As society develops, people's needs for seating are becoming increasingly diverse, and the application scenarios are becoming wider. In some scenarios, armrests are gradually moving beyond simply providing a place to hold on or lean against; they can also play a certain protective and auxiliary role. For example, when they are used by special groups of people or in special occasions including but not limited to gaming and VR experiences, armrests can better protect the user's personal safety and enhance the experience.

[0004] In these application scenarios, a safer way to use the handrail is to place it on the outside of the body for protection and assistance.

[0005] However, in existing technologies, whether it's armrests or guardrails, components generally use pneumatic pressure output to change their relative position to the seat, thus securing the user. The problem with pneumatic output is that it's often configured with a precise output position, meaning the armrest's adjustment range often cannot be tailored to the user's actual needs. This is not user-friendly for users of different body types. In some gaming and VR experiences, excessively large safety gaps between the armrest and the user may pose safety hazards, or the armrest being too close to the user can lead to a poor user experience. Similarly, the seatbelt-style safety strategy used in some seats cannot simultaneously provide a good user experience and a high level of safety. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the embodiments, but the protection scope of the present invention is not limited thereto.

[0027] This utility model relates to an adjustable wraparound seat, including a seat 1, a backrest 2 at the rear of the seat 1, and armrests 3 on both sides of the seat. The armrests 3 are configured to cooperate with the seat through an adjustable wraparound component.

[0028] In this utility model, the direction in which the user normally sits behind the seat and faces is defined as "forward";

[0029] The seat 1 and backrest 2 are set using conventional technology, and those skilled in the art can set them according to their needs. Unlike the prior art, the armrest 3 of this utility model cooperates with the seat through an adjustable wrap-around component. In actual application, the adjustable wrap-around component can be set to cooperate with the rear of the seat 1 or the back side (rear side) of the backrest 2 of the seat according to the actual situation.

[0030] The adjustable wrap-around assembly includes a support base 4 located at the rear of the backrest 2, a cantilever 5 provided in conjunction with the support base 4, and an armrest 3 located at the front end of the cantilever 5; a rotating unit is provided in conjunction with the support base 4, and a telescopic unit is provided in conjunction with the cantilever 5.

[0031] The support base 4 includes an isolation cavity 6 located at the rear of the chair back 2, and two fixing cavities 7 connected upward to the other end of the isolation cavity 6. A corresponding cantilever 5 is provided at the top of any of the fixing cavities 7.

[0032] In this invention, the support seat 4 of the adjustable wrap-around assembly is located on the rear side of the backrest 2 to avoid excessive vertical height of the support seat 4, which would result in excessive weight and cost of the seat. A cantilever 5 is provided on the top of the support seat 4 to connect the armrest 3. When the cantilever 5 rotates in conjunction with the rotating unit of the support seat 4, it can drive the armrest 3 to simultaneously adjust the width of the wrap-around area of ​​the cantilever 5 and the armrest 3. Furthermore, a telescopic unit is provided on the cantilever 5 to adjust the relative position of the armrest 3 and the cantilever 5.

[0033] Specifically, the support base 4 is isolated from the backrest 2 by the isolation cavity 6. This is to leave enough room for adjustment and to avoid mutual interference between the adjustable wrap-around component and the user, such as vibration. Two fixed cavities 7 are set upward at the end of the isolation cavity 6 away from the backrest 2, and rotating units are set in each cavity to adjust the corresponding cantilever 5 to achieve rotation.

[0034] In this invention, the rotating unit is configured in at least two embodiments. Example

[0035] In this embodiment, a first rotary motor 8 is provided in each fixed cavity 7. The first rotary motor 8 drives the first connector 9 at its output end to rotate, and then drives the fixed seat 10 in the cantilever 5 to rotate through the first connector 9, so as to achieve the effect of rotating the cantilever 5.

[0036] In Embodiment 1, since the cantilever 5 is controlled by two first rotary motors 8 respectively, in order to achieve a better wrap-around effect, the two first rotary motors 8 are sampled in real time by sampling terminals. After the signal obtained by the sampling terminals is input to the comparison circuit, the comparison circuit outputs the comparison result to the MCU, and the MCU controls the output power of the two first rotary motors 8 to be consistent with the rotation of the cantilever 5. Example

[0037] In this embodiment, a second rotary motor (not shown in the figure) is provided in the isolation cavity 6. The output of the second rotary motor is switched to the synchronous output shaft 12 through the first bevel gear set 11. The synchronous output shaft 12 is perpendicular to the output shaft of the second rotary motor. The synchronous output shaft 12 is located in the space under the two fixed cavities 7. Then, the output direction is switched to the corresponding rotary shaft 14 again by the two sets of second bevel gear sets 13 of the synchronous output shaft 12. The rotary shaft 14 rotates in the corresponding fixed cavity 7, driving the second connecting piece 15 at its top to rotate, thereby driving the fixed seat 10 and cantilever 5 connected to it to rotate.

[0038] Although Example 1 and Example 2 emphasize different control methods, they are both feasible technical means.

[0039] In this utility model, the configuration of the first connector 9 and the second connector 15 is easy for those skilled in the art to understand. They are used to enable the corresponding first rotary motor 8 and second rotary motor to be connected to the cantilever 5 through the first connector 9 and the second connector 15. Those skilled in the art can customize the structure of the first connector 9 and the second connector 15 according to their needs.

[0040] The fixed base 10 is located at one end of the cantilever 5 facing the fixed cavity 7. The telescopic unit includes a telescopic motor 16 that is configured to cooperate with the fixed base 10. The output end of the telescopic motor 16 is configured to cooperate with the handrail 3. The other end of the cantilever 5 is sleeved on one end of the handrail 3.

[0041] A positioning plate 17 is provided at the output end of the telescopic motor 16, and the positioning plate 17 is fixedly connected to the handrail 3.

[0042] In this utility model, in addition to adjusting the width of the circumference, it is also possible to achieve the "inward" action after the approximate position is adjusted.

[0043] Specifically, a telescopic motor 16 is installed at the fixed seat 10 of the cantilever 5. The output end of the telescopic motor 16 is connected to one end of the handrail 3, that is, the telescopic motor 16 can move the handrail 3 relative to the other end of the cantilever 5.

[0044] In this process, the positioning plate 17 is necessary. Its outer edge can be connected to the handrail 3, and its interior is connected to the output end of the telescopic motor 16 to achieve the combination.

[0045] The handrail 3 includes a straight pipe section that cooperates with the adjustable wrap-around assembly and an arc pipe section located at the front of the straight pipe section.

[0046] The front ends of the arc tube sections of the two handrails 3 are respectively provided with matching fasteners 18.

[0047] In this invention, a straight pipe section is used to achieve the cooperation between the handrail 3 and the adjustable wrap-around component, which facilitates the setting of the telescopic unit, while an arc pipe section is used to accommodate users of different body types.

[0048] Furthermore, when used as a standard component, the maximum adjustable position between the handrail 3 and the adjustable wrap-around assembly (cantilever 5) is limited by the fastener 18 that fits at the front end of the arc tube section of the two handrails 3, thus avoiding damage to the telescopic motor 16 due to over-adjustment; the fastener 18 here can be implemented in the form of male and female fasteners, and the two are interference fit.

[0049] In the specific implementation process, the drive of the first rotary motor 8 or the second rotary motor and the telescopic motor 16 is controlled by the controller, which can be controlled by remote control or by setting actions.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
