Description

TECHNICAL FIELD

[0001] The utility model relates to furniture technical field especially is involved in a kind of posture-correcting seat of protecting spine. BACKGROUND

[0002] Desk chair is the teaching tool frequently used by students, and the chair back of desk chair is designed to help students rest against the backrest when reading and writing, so as to relieve the pressure on the waist and back of students, and reduce the hazards caused by the lack of support for the waist and back, such as the close-to-eye distance less than 25 cm, eye fatigue caused by close-to-eye distance, and spinal curvature caused by crouching.

[0003] However, in actual use, the chair back of desk chair basically does not provide support for the waist and back, mainly because the distance between desk and chair is too large, and students must have a certain distance when sitting on desk chair, so that people can enter and sit down. When sitting down, the distance between desk and chair is too large, and it is possible to move forward by lifting the chair with both hands, but the knees cannot be lifted higher to lift the chair into the clearance under the desk, and the distance between the abdomen and the desk edge is greater than one fist, so the body must be inclined forward or the hips are moved forward, causing the chair back of desk chair to be suspended and unable to support the waist and back. The chair back is virtually non-existent, and does not play the role of a chair, but only functions as a stool. After sitting for a few minutes, students naturally incline forward to crouch on the desk to relieve the pressure on the upper body, causing the viewing distance to be less than one foot again, and long-term use can cause myopia and spinal curvature.

[0004] In addition, although the existing seat is provided with universal wheels, the distance between the seat and the desk can be adjusted without lifting the seat, but when the user leans against the chair back of the seat, the seat may move away from the desk.

[0005] The applicant finds that the prior art at least has the following technical problems:

[0006] In the prior art, there is a lack of a structure on the seat that can be moved flexibly in front of the desk and will not move backward when the user leans against the chair back. CONTENT OF THE UTILITY MODEL

[0038] Embodiment three:

[0039] The difference between the embodiment three and the embodiment two is:

[0040] The utility model provides a kind of posture-correcting and spine-protecting chair, the roller structure is pulley 2, stop brake structure is foot pad 3 and pressure retraction wheel 4, pressure retraction wheel 4 inside is provided with spring. When user is seated on chair and advances to the direction close to table, user's body leans forward and forces forward, and the free end of rear foot support 12 will be raised, so that foot pad 3 will reduce contact area (contact friction force reduces, is driven forward by pulley 2), while the pressure borne by pressure retraction wheel 4 reduces and extends rear foot support 12, pulley 2 will make forward sliding under the action of user's force, so that chair can slide forward, while pressure retraction wheel 4 will also assist chair to advance, when the distance of moving abdomen from table rail is equal to or less than one fist distance, user's correct sitting posture and back adhere to chair's chair back, at this time, the free end of rear foot support 12 will not be raised, and foot pad 3 will be in contact with ground, so that there will be greater friction between foot pad 3 and ground, while pressure retraction wheel 4 will retract into rear foot support 12 due to the increase of pressure borne, when user exerts force on chair back, due to the friction between foot pad 3 and ground, chair will not slide backward, at this time, chair back supports waist and back, so that people want to lie prone, but it is not easy to lie prone due to the support of waist and back, back adheres to chair back, reduces spinal pressure, reduces humpback and neck pressure, maintains one foot sight distance, prevents and controls the occurrence and development of myopia, improves cerebral blood supply, helps to improve learning efficiency and concentration.

[0041] Embodiment four:

[0042] The utility model provides a kind of posture-correcting and spine-protecting chair, it is an office chair, it is the tool frequently used by office worker, including base 1, chair rod connecting piece 6 and seat body 7, base 1 is provided with front foot support 11 and rear foot support 12, front foot support 11 is installed with roller structure, rear foot support 12 is installed with stop brake structure, the both ends of chair rod connecting piece 6 are respectively fixedly connected with seat body 7 and base 1, chair rod connecting piece 6 is liftable component, specifically can chair rod connecting piece 6 be liftable screw rod component or non-rotating gas rod component, i.e. chair rod connecting piece 6 can only be lifted, cannot be rotated, seat body 7 will not rotate relative to base 1 by chair rod connecting piece 6, so that the orientation of seat body 7 will not change with the position of front foot support 11, seat body 7 can change height by chair rod connecting piece 6.

[0043] The base 1 is a claw disc structure, the number of the front legs 11 is at least two, and the number of the rear legs 12 is one or more. The roller structure is a universal wheel 5, and the stop structure is a pressure self-locking wheel 8. When a user sits on the seat and moves towards a desk, the user leans forward and exerts force forward, the free end of the rear legs 12 is slightly tilted up, the pressure self-locking wheel 8 bears reduced pressure, and the universal wheel 5 slides forward under the action of the force exerted by the user, so that the seat slides forward. At this time, the user sits upright and the back is attached to the backrest of the seat. When the user exerts force on the backrest, the pressure self-locking wheel 8 is pressed and locked due to increased pressure, so that the seat does not slide backward. At this time, the backrest supports the waist and back, so that the user is not easy to lean down, the back is attached to the backrest, the spine pressure is reduced, and the humpback and neck pressure are reduced.

[0044] Embodiment five:
