Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture technology, and in particular to a chair component and a chair. Background Technology
[0002] Currently, chairs are widely used in all aspects of people's lives. Depending on the place of use, chairs include office chairs, car seats, conference chairs, and many more. The backrest is one of the important components of many modern chairs, providing comfort for the user's back. Ideally, the backrest should be designed to be adjustable. This is because it needs to be adjusted according to the differences in individual user physique and habits, and even for the same user, adjustments to the position and angle relative to the user's back are necessary due to changes in posture or the angle of the backrest during use.
[0003] In the past, most chairs had fixed backrests, resulting in poor comfort. Sitting in such chairs for extended periods, such as while listening to reports or watching performances, would cause discomfort. Although some adjustable chair components have emerged, their structures remain overly complex and their production costs are high. Utility Model Content

[0043] Reference Figures 1 to 9The present invention relates to a chair component, including a seat 100, a first support portion 110, and a second support portion 120 extending upward from the first support portion 110. The first support portion 110 is horizontally positioned. During use, a person sits on the first support portion 110, and the upwardly extending second support portion 120 supports the chair component 200. The lower end of the chair component 200 is hinged to the second support portion 120. A mounting seat 210 is provided on the rear side of the chair component 200. An elastic element 300 is attached to the mounting seat 210 at one end and abuts against the second support portion 120 at the other end. In this embodiment, the elastic element 300 can be a spring. Alternatively, a combination of springs and foam components, or other structures that can achieve the same effect (not listed here), can be used. The elastic element 300 can be connected horizontally or obliquely between the mounting base 210 and the second support 120. Through the action of the elastic element 300, when a person sits on the first support 110 and leans back against the chair component 200, the upper part of the chair component 200 rotates backward and squeezes the elastic element 300. At this time, the elastic element 300 plays a buffering role, making the person's backward lying process smoother and more comfortable. After sitting up, the elastic potential energy stored in the elastic element 300 is released, and the elastic element 300 drives the chair component 200 to rotate forward and reset.
[0044] The application of the above-mentioned chair components has at least the following beneficial effects: the lower end of the chair component 200 is hinged to the second support part 120, allowing the upper part of the chair component 200 to rotate relative to the seat 100. An elastic element 300 is provided between the mounting seat 210 on the rear side of the chair component 200 and the second support part 120 to increase the cushioning when the chair component 200 rotates backward and to enhance the restoring effect of the chair component 200. During prolonged sitting, when the back is against the chair component 200 and the chair component 200 is reclined, the upper part of the chair component 200 rotates backward, and the elastic element 300 provides a cushioning effect, slowing down the speed and amplitude of reclining, thus improving the comfort of reclining. Furthermore, the entire chair back structure is simple, easy to assemble and disassemble, and reduces production costs.
[0045] According to some embodiments of this utility model, refer to Figure 9It also includes a fixing plate 220, which is detachably connected to the mounting base 210. The fixing plate 220 is provided with a retaining ring 221 for connecting the elastic element 300. One end of the elastic element 300 is fixedly connected by the retaining ring 221, which prevents the elastic element 300 from becoming loose or misaligned. When disassembling and assembling the elastic element 300, only the fixing plate 220 needs to be disassembled and assembled at the same time, which is simple and convenient. At the same time, the fixing base 220 is connected to the mounting base 210 by bolts. In some embodiments, the mounting base 210 has multiple threaded holes 211 on its periphery, and the fixing plate 220 has multiple through holes 222 at the corresponding positions. The threaded holes 211 and the through holes 222 are coaxial. In some other embodiments, the mounting base 210 has a threaded hole 211 at its center, and the fixing plate 220 has a through hole 222 at its center. The through hole 222 and the threaded hole 211 are coaxial.
[0046] According to some embodiments of this utility model, a grid structure 121 is inclinedly provided on the front side of the second support part 120, the central axis of the elastic member 300 is perpendicular to the end face of the grid structure 121, and the other end of the elastic member 300 abuts against the end face of the grid structure 121. The grid structure 121 provides support for the elastic member 300. At the same time, the grid structure 121 has a good shrinkage rate and a high yield during the injection molding process. In some other embodiments, a flat plate support structure can also be used at this location, or a mounting base 210 and a fixing plate 220 can also be provided on the front side of the second support part 120, and the two ends of the elastic member 300 can be connected to the buckles 221 on the two fixing plates 220 respectively, so that the elastic member 300 is more securely and stably fixed.
[0047] According to some embodiments of this utility model, there are two of each of the elastic element 300, mounting base 210, fixing plate 220 and grid structure 121. The above two structures are arranged in the left and right directions, so that the supporting force of the elastic element 300 on the chair component 200 is more uniform, and the comfort of sitting and leaning is improved.
[0048] According to some embodiments of the present invention, the second support part 120 is provided with a plurality of guide grooves 122, and the rear side of the chair part 200 is provided with a plurality of guide plates 230. The guide plates 230 are slidably disposed in the guide grooves 122. During the reclining process, the guide plates 230 slide in the guide grooves 122 to limit the displacement direction of the chair part 200, avoid the chair part 200 from tilting, and increase comfort. At the same time, a baffle 231 is also provided on the rear side of the guide plate 230. The baffle 231 is used to prevent the guide plate 230 from dislodging forward from the guide grooves 122 during the resetting process of the chair part 200.
[0049] According to some embodiments of the present invention, the lower end of the second support part 120 is provided with a hinge seat 130 by bolts, and a plurality of ear plates 240 are provided at the corresponding position on the rear side of the chair part 200. The lower end of the chair part 200 is hinged to the second support part 120 by means of a pivot 250 passing through the ear plates 240 and the hinge seat 130.
[0050] According to some embodiments of the present invention, a cover 400 is also provided on the rear side of the second support part 120. The cover 400 is used to cover the bolts on the second support part 120 to improve the overall aesthetics of the chair back and also to prevent dust from the bolt connection parts.
[0051] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.
[0052] Although some embodiments of the present invention have been shown and described in this specification, the present invention should not be limited to the above embodiments. As long as they achieve the technical effects of the present invention by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles of this disclosure, without departing from the principles and purpose of the present invention, should be included within the scope of protection of this disclosure and should be considered to fall within the protection scope of the present invention.
