Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture technology, specifically to a biomimetic leisure chair. Background Technology
[0002] A lounge chair is a chair we use to enjoy our leisure time. Unlike dining chairs and office chairs, these chairs are not formal; they have a touch of personality and provide both visual and physical comfort.
[0003] There are some existing leisure chairs, such as the utility model patent document with authorization announcement number "CN220069250U" and patent name "A Leisure Chair with Adjustable Headrest", which discloses a leisure chair that includes a throttle and a backrest.
[0004] When neck support is needed, turn the handle to adjust the headrest to a suitable upper body height for the user, thus supporting the user's shoulders and neck. However, when the user is resting, their back is pressed against the back of the chair due to the sitting posture. Over time, this can cause back pressure and muscle tension, affecting comfort. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a biomimetic leisure chair to solve the technical problem mentioned in the background art: when the user's neck is supported by the pillow of some existing leisure chairs, the user's back is pressed against the back of the chair due to the sitting posture, which can easily lead to muscle tension in the user's back over a long period of time, affecting the comfort of use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A biomimetic lounge chair includes a seat, a backrest fixed to one side of the top of the seat, and support legs fixed to the bottom of the seat. A headrest and a lumbar support are provided on the backrest's backrest surface. A connecting frame is fixed to the side of the backrest away from its backrest surface. An installation sleeve is fixed to the connecting frame. A first cylinder is fixed inside the installation sleeve. The telescopic end of the first cylinder passes through the backrest and is fixed to the lumbar support. The seat has a height-adjustable and reciprocating leg rest.
[0008] Working principle:
[0009] First, the user sits on the seat, with their neck and lower back resting on the headrest and lumbar support respectively. To adjust the lumbar support, the user pushes it against their lower back using the first cylinder. For leg support, the user can move the leg rest and adjust its height to provide support for their legs.
[0010] The beneficial effects of this utility model are as follows:
[0011] During use, the first cylinder provides support for the lower back of users who are sitting or leaning against it. It has a simple structure, good effect, and strong practicality. The lumbar support provides support for the lower back of different users, preventing the lower back from being compressed when the user leans against the headrest, which would cause muscle tension and affect the comfort of use. It also has a simple structure and good effect. At the same time, it also supports the legs, preventing leg muscle tension caused by prolonged sitting. Attached Figure Description

[0017] How to use:
[0018] When lumbar support is needed for different users, the first cylinder 7 pushes the mounting plate 8 through its telescopic end, thereby causing the push plate 9 and multiple massage blocks 36 to come into contact with the user's lumbar region. When the user feels fatigue or discomfort in their lumbar region, the heating wire 37 inside the massage block 36 is activated, and at the same time, the first cylinder 7 pushes the push plate 9 back and forth, so that the massage blocks 36 and the heating wire 37 heat and massage the user's lumbar region.
[0019] When the height of the headrest 4 needs to be adjusted, the user slides the headrest 4 back and forth, thereby moving the slider 17 back and forth on the sliding frame 15. When the headrest 4 moves to the appropriate height, the user stops sliding. At this time, the user screws the bolt 18 into the slider 17 so that the thread of the bolt 18 passes through the slider 17 and abuts against the sliding frame 15.
[0020] When the legs need to be placed, the rotating gear 35 moves the mounting block 22, which in turn moves the support plate 26 via the second cylinder 23 and the third cylinder 25. When the height of the support plate 26 needs to be adjusted, the second cylinder 23 and the third cylinder 25 push the support plate 26 to adjust its height. When the legs placed on the support plate 26 need to be massaged, the dual-head motor 29 is activated, which drives the two threaded rods 30 to rotate, which in turn moves the support block 27 and the massage protrusions 28 to massage via the bushing 31.
[0021] Beneficial effects:
[0022] The buffer block 13 and spring 12 provide buffer protection for the extension and retraction end of the first cylinder 7, preventing excessive impact from damaging the extension and retraction end of the first cylinder 7 when the waist is leaning against it; the gear 35 and rack 33 facilitate the movement of the support plate 26, which has a simple structure and good effect; the bolt 18 facilitates the fixing of the headrest 4, which is easy to adjust and easy to position.
