Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

The embodiment provides a bar chair, as shown in fig. 1~ 4, bar chair includes the bar chair seat and the bar chair back of the chair, and the top of bar chair seat is provided with the bar chair bedplate, and the bar chair back of the chair is connected in the bar chair bedplate.

Because the back plate of the traditional bar chair is short, the back plate is not suitable for the back leaning height of a human body and is not in accordance with human engineering, so that a person can better fit the back of the chair when the spine leans against the back of the chair, the pressure born by the spine is large, and a good relaxing effect cannot be achieved.

In order to solve the above problem, the present embodiment provides a bar chair back including a back support 1 for connecting with a bar chair seat, and a back plate 2 connected to the top of the back support 1. The backrest support piece 1 is used for heightening the backrest plate 2, so that the backrest plate 2 is suitable for the supporting position of the back of a human body, and a comfortable supporting effect is achieved.

The backrest plate 2 comprises a connecting part 21 connected to the backrest support part 1 and protective parts 22 symmetrically arranged on two sides of the connecting part 21, the connecting part 21 is located on the inner side surface of the backrest support part 1, and the inner side surface of the connecting part 21 forms an outer convex cambered surface. When leaning on, the back of a human body contacts the convex cambered surface, the convex cambered surface blocks the back from contacting the backrest support part 1, and the comfort level of the back is improved. In this embodiment, the inner side is the side of the bar chair back close to the human body, and the outer side is the side departing from the human body.

The longitudinal length of the protection part 22 is firstly increased and then reduced from one side close to the connecting part 21 to the outside, and the inner side surface of the protection part 22 is attached to the concave cambered surface of the back of a human body. The two protection parts 22 symmetrically support the two sides of the back, and particularly correspond to the positions of the waist parts at the two sides of the spine of the human body, so that the better supporting effect on the waist part can be achieved, and the leaning of the human body is more comfortable.

The edge of protection part 22 turns over towards the lateral surface of protection part 22 and forms and roll over 23, strengthens the intensity of protection part 22 on the one hand, and on the other hand can avoid the uncomfortable sense that the edge of protection part 22 and human contact caused. When the bar chair is used, the back of the bar chair can better support the back, and the back comfort is improved.

The back support 1 includes a first end 11 for connection with the bar chair seat, a second end 12 to which the back plate 2 is connected, and a support 13 connected between the first end 11 and the second end 12. An arc surface for connecting the first end portion 11 and the support portion 13 is formed between the first end portion 11 and the support portion 13. The first end portion 11 is provided with a plurality of mounting holes, and the first end portion 11 is connected to the bottom surface of the bar chair seat plate through a connecting piece penetrating through the mounting holes. The second end portion 12 is welded or connected to the connecting portion 21 by a connecting member such as a screw.

The height of the backrest support 1 is 20-40 cm. For example, the height may be 20cm, 25cm, 30cm, 35cm, 40cm, etc. Within the height range, the backrest plate 2 can correspond to the optimal supporting position of the back of the human body, so that the waist and the back of the human body can be effectively supported, and the comfort level of the human body is improved.

The angle between the first end portion 11 and the support portion 13 is 75-85 deg.. For example, the angle between the first end portion 11 and the support portion 13 may be 75 °, 77 °, 79 °, 80 °, 81 °, 83 °, 85 °. Within the above angle range, the support portion 13 can better support the backboard 2, effectively offset the acting force applied by the back of the human body to the backboard 2, and avoid the deformation of the support portion 13.

To further reinforce the strength of the support portion 13, the middle portion of the support portion 13 is arched inward and a reinforcing groove 131 is formed outward. The reinforcing groove 131 can effectively improve the strength and rigidity of the supporting portion 13, and prevent the supporting portion 13 from being bent. The width of the support portion 13 gradually increases from the middle toward both ends.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
