Technical Field

[0001] This application relates to the field of chair technology, and in particular to a health care office chair. Background Technology

[0002] As more and more jobs shift to office work, people spend a significant amount of time sitting in office chairs every day. To ensure human health, ergonomic principles have been incorporated into office furniture design. By studying the interaction between human body structure and the work environment, the aim is to design office chairs that reduce physical stress, improve comfort, and promote health.

[0003] Patent CN207253147U discloses an office chair with a headrest that allows users to rest their heads on for temporary comfort when they feel tired after sitting in front of a computer for a long time. The applicant believes that the above technology has the following problem: when some female users use this office chair, their hair is tied back, and when they need to lean their heads against the headrest, the tied-back hair can affect their comfort. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems existing in the prior art by proposing a health-promoting office chair.

[0005] This application can be achieved through the following technical solution: a health care office chair, including a seat body and a headrest installed on the seat body for supporting the head, wherein a clearance groove is provided on the headrest.

[0006] In the above technical solution, the seat body can support the human body. By setting a clearance groove on the headrest, the clearance groove can avoid the hair tied up or the hair bun on the human body, thereby ensuring the comfort of the female user's head resting on the headrest.

[0007] Furthermore, the headrest includes a fixed base and a soft pad mounted on the fixed base. The fixed base is slidably connected to the seat body. The fixed base has several adjustment holes. The adjustment holes are connected to the seat body by screws to fix the position of the fixed base relative to the seat body.

[0008] In the above technical solution, the fixed seat is slidably connected to the seat body, and the user can adjust the height of the headrest as needed.

[0009] Furthermore, the seat body is provided with a mounting seat that can contact the human leg. The mounting seat is provided with two sets of leg fixing components. The leg fixing components include two fixing straps, a male buckle, and a female buckle installed on the mounting seat. The male buckle and the female buckle are installed on the two fixing straps one-to-one, and the male buckle can be fastened to the female buckle.

[0010] In the above technical solution, people often cross their legs when sitting, and the leg fixing component can limit the movement of the lower leg.

[0011] Furthermore, the seat body includes a support seat for contacting the buttocks of a human body and a backrest for contacting the back of a human body. The backrest is rotatably connected to the support seat, and the backrest is fixed in position relative to the support seat by a fixing component.

[0012] In the above technical solution, the chair back and the support seat are rotatably connected, and the user can adjust the position of the chair back according to different needs during office work or lunch break.

[0013] Furthermore, the fixing component includes a fixing plate installed on the seat body, a connecting plate formed on the seat back, and a connector connecting the fixing plate and the connecting plate. The fixing plate has several through holes for the connector to pass through, and the several through holes are located at the edge of the fixing plate. The connecting plate has connecting holes for the connector to pass through.

[0014] In the above technical solution, after rotating the chair back to a suitable angle, the through hole and the connecting hole are connected by a connector, so that the position of the chair back relative to the support seat can be fixed.

[0015] Furthermore, the connector includes a rod that passes through both the through hole and the connection hole, several sliders that are slidably connected to the rod, and a spring that forces the sliders to protrude from the outer wall of the rod along its length. The sliders are evenly distributed at both ends of the rod along its length. The sliders can contact the side wall of the fixed plate away from the connecting plate or the side wall of the connecting plate away from the fixed plate.

[0016] In the above technical solution, by pressing the slider at one end of the insertion rod along its length, the insertion rod is simultaneously inserted into the through hole and the connecting hole. Then, the slider is released. At this time, the slider at one end of the insertion rod along its length can contact the side wall of the fixing plate away from the connecting plate, and the slider at the other end of the insertion rod along its length can contact the side wall of the connecting plate away from the fixing plate. At this time, the chair back can be fixed relative to the support seat.

[0017] Furthermore, the slider has a bevel formed on it, and the through hole or connecting hole can press the bevel to retract the slider into the insert rod.

[0018] In the above technical solution, the through hole or connecting hole can press the inclined surface to make the slider retract into the insertion rod, eliminating the need to manually press the slider and improving convenience.

[0019] Furthermore, a support seat that can contact the ground is rotatably mounted on the back of the chair, and a rubber sleeve is fitted on the bottom of the support seat.

[0020] In the above technical solution, by setting up a support seat, the support seat can provide more stable support for the chair back when the human body is lying down. Compared with the metal support seat directly hitting the ground, by setting up a rubber sleeve, when the person puts down the support seat, the rubber sleeve can contact the ground, and there will be no excessive impact noise when the rubber sleeve contacts the ground.

[0021] In summary, this application has the following technical advantages: the seat body can support the human body, and by providing a clearance groove on the headrest, the groove can avoid hair tied up or styled in a bun, thereby ensuring the comfort of female users' heads resting on the headrest. The fixed seat is slidably connected to the seat body, allowing users to adjust the height of the headrest as needed. When sitting, people may inadvertently cross their legs; the leg-fixing component can limit the movement of the lower legs. Attached Figure Description
