Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] Such as Figure 1 ~ Figure 2 As shown, the massage chair of this embodiment includes a base, a backrest 1, a seat 2, a leg 3, a driving device and a linkage mechanism, wherein the base plays a role in supporting the entire massage chair, and the base includes a chassis 41 and a support frame 42, the bottom frame 41 is horizontally arranged, the support frame 42 is vertically fixed on the bottom frame 41 and is positioned at both sides of the backrest 1, and the linkage is realized through a movable hinge between the seat portion 2 and the leg portion 3, and the seat portion 2 is hinged on the support frame 42 through the pin shaft 21. In order to avoid rotational interference between the backrest part 1 and the seat part 2, and to make the backrest part 1 have a larger rotation range, the backrest part 1 and the support frame 42 are pas...

The invention relates to a massage chair capable of simulating the zero gravity state. The massage chair comprises a base and a backrest part, a seat part and a leg part which are arranged on the base. The massage chair is characterized in that the backrest part and the seat part are hinged on a support of the base in a movable mode; a body of the driving device is hinged on an underframe of the base; the end part of a driving piece is hinged at the bottom of the seat part; one end of a first connecting rod of a connecting rod mechanism is hinged on the underframe of the base, and one end of a second connecting rod is hinged at the bottom of the seat part; the other end of the first connecting rod is hinged with the other end of the second connecting rod to form a movable hinged part; oneend of a third connecting rod is hinged on the movable hinged part, and the other end of the third connecting rod is hinged at the bottom end of the backrest part; and one end of a fourth connecting rod is hinged at the bottom end of the backrest part, and the other end of the fourth connecting rod is connected to the leg part in a movable mode. In the massage chair, angles of the backrest part, the seat part and leg part are regulated simultaneously by using one driving device and matching with the connecting rod mechanism. The massage chair has a simple integral structure and is stable in regulation process, and the comfortableness and safety of using the massage chair are improved.
Description
technical field [0001] The invention relates to a massage chair, in particular to a massage chair capable of simulating a zero-gravity state. Background technique [0002] The "zero gravity" massage chair is designed according to the principle of NASA's space capsule seat. When an astronaut sits on a space capsule seat to rest, his back and thighs usually form an angle of 128° (error ± 7°), the thigh and the calf form 133° (error ±8°), and the knee is slightly higher than the heart. At this time, the gravity is evenly distributed throughout the body, and the human spine is kept in an S-shaped curve. The sitting posture helps to relax the spine, relieve muscle tension, and promote blood circulation in the human body. People apply the principle of space capsule seats to massage chairs through simulation technology, so as to achieve a completely relaxed, natural and comfortable massage posture. [0003] At present, commercially available zero-gravity massage chairs are expensi...
