Description
Technical Field
The utility model relates to the technical field of furniture, concretely relates to seat.
Background
The office chair is an indispensable office supply for modern office. To increase the comfort of the human body, technicians put a lot of effort on the design of the seat. There are many ergonomic seat designs among the prior art, thereby some seats in order to improve the human travelling comfort reach and better support the back through setting up the spring structure backing up. The design structure of the backrest in the prior art is complex, and the comfort is not enough.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the problem among the prior art, provide a seat.
The purpose of the utility model is realized through the following technical scheme:
a chair comprises a seat board and a backrest, wherein the backrest comprises a fixed rod, an upper back supporting surface and a lower back supporting surface; the backrest is connected with the seat plate through a fixing rod; the two fixing rods are respectively arranged on two sides of the backrest; two sides of the upper back supporting surface are fixedly connected with the fixed rod; the upper edge of the lower back supporting surface is connected with the upper back supporting surface, and other edges of the lower back supporting surface are free ends.
The seat is arranged by dividing the backrest into an upper back supporting surface and a lower back supporting surface. Wherein the top end of the lower back support surface is connected with the upper back support surface, and the other edges are in a free end state which is not connected with other parts. So configured, the support of the lower back support surface to the lower back may be better. The lower back support surface, when squeezed, deforms around the edges of the connection to the rear of the seat, providing a better fit to the lower back for comfort. When the pressure is removed, the lower back support surface returns to its original position and shape.
Preferably, the lower back support surface has deformation recovery.
The lower back support surface is preferably made of a hard PP material, and on the one hand, only one edge of the lower support surface is fixed with the upper support surface, and the lower back support surface can easily rotate around the edge to deform after receiving pressure. In addition, the PP material has certain elasticity itself, can extend after receiving pressure and laminate with lower back better, improves the comfort level.
Preferably, the lower back support surface is arc-shaped, a protrusion is arranged in the middle of the arc-shaped lower back support surface, and the protrusion faces the front side of the seat.
The middle part of the lower back supporting surface forms a bulge, and the bulge position is used as a waist rest, so that the waist rest can better fit the physiological curvature of a human body, and the comfort level is further improved.
Preferably, a plurality of air holes are formed in the lower back supporting surface.
In the use process, the time that the lower back supporting surface is attached to the human body is longest, and the air holes are formed, so that heat dissipation is facilitated.
Preferably, the upper back support surface comprises a front support surface and a rear support surface, the rear support surface is connected with the fixing rod, and the upper edge of the lower back support surface is fixed between the front support surface and the rear support surface.
The connection between the lower back support surface and the upper back support surface can be varied. In order to provide the stability of connection, set up the back holding surface as preceding holding surface and back holding surface, set up back holding surface down between preceding holding surface and back holding surface, through the both position of fastening the connection better, improve the stability of connection.
Preferably, a protection pad is arranged on the front side of the front supporting surface.
Preferably, a headrest is provided at the top end of the front support surface.
In order to further provide the comfort of the seat, a protective pad made of sponge or other soft materials is added on the upper back supporting surface. The headrest is connected and arranged at the top end of the front supporting surface, so that the head of a user can be conveniently supported.
Compared with the prior art, the utility model discloses following technological effect has:
the utility model discloses a seat is through being provided with the holding surface of bearing the back and the holding surface of bearing the back down by leaning on to the holding surface of bearing the back sets up to one side fixedly down, and other structures for the free end have increased the support nature and the laminating nature to the back down, further provide the travelling comfort of seat.
