Abstract
The utility model provides an elastic connecting device of back, belongs to seat accessory technical field. It includes first connector of being connected with the back and the second connector of being connected with the chair back frame, first connector and second connector between connect through the elastomer that sets up. A foretell elastic connecting device of back, simple structure, reasonable in design, through the effect of first elastomer and second elastomer, the relative second connector of first connector can twist reverse and be crooked, and back back of the body frame relatively can change variable angle, has improved use comfort.
Description
Technical field
The utility model belongs to seat part technical field, is specifically related to a kind of elastic connecting device of back.
Background technology
Usually, chair comprises cushion and backrest.Backrest is fixedly connected with chair backrest.Backrest designs according to body curve, but there are differences due to each individuality, cannot ensure that everyone body curvature and backrest are fitted completely, thus affect the supporting degree of backrest to the person, affect comfortableness.
Utility model content
For prior art Problems existing, the purpose of this utility model is to design the technical scheme of the elastic connecting device providing a kind of back.
The elastic connecting device of described a kind of back, is characterized in that comprising the first connector be connected with back and the second connector be connected with chair backrest, and the elastomer by arranging between the first described connector and the second connector connects.
The elastic connecting device of described a kind of back, it is characterized in that described elastomer comprises relative back vertical direction the first elastomer setting up and down and the second elastomer, the first described connector two ends and the two ends of the second connector connect the first elastomer and the second elastomer respectively.
The elastic connecting device of described a kind of back, is characterized in that the first described connector and the second connector are U-shaped structure.
The elastic connecting device of above-mentioned a kind of back, structure is simple, reasonable in design, by the first elastomer and the second elastomeric effect, relative second connector of first connector can reverse and bend, and the relative backrest changeable angle of backrest, improves comfort.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present utility model;
Fig. 2 is main TV structure schematic diagram of the present utility model;
Fig. 3 is perspective view of the present utility model.
In figure: 101-first connector; 102-second connector; 103-first elastomer; 104-second elastomer; 2-back; 3-chair backrest.
Detailed description of the invention
The utility model is further illustrated below in conjunction with Figure of description.
As shown in the figure, a kind of elastic connecting device of back is comprised the first connector 101 be connected with back 2 and is connected by the elastomer that arranges between the second connector 102, first connector 101 be connected with chair backrest 3 and the second connector 102.As preferred structure, the first connector 101 and the second connector 102 are U-shaped structure, and opening is relative, and size is inconsistent.As preferred structure, elastomer comprises relative back 2 vertical direction the first elastomer 103 and the second elastomer 104 setting up and down.First connector 101 two ends connect the first elastomer 103 and the second elastomer 104 respectively, and namely the upper end of the first connector 101 connects the first elastomer 103, and lower end connects the second elastomer 104.The two ends of the second connector 102 connect the first elastomer 103 and the second elastomer 104 respectively, and namely the upper end of the second connector 102 connects the first elastomer 103, and lower end connects the second elastomer 104.
The elastic connecting device of above-mentioned a kind of back passes through the effect of the first elastomer 103 and the second elastomer 104, relative second connector 102 of first connector 101 can reverse and bend, back 2 is chair backrest 3 changeable angle relatively, improves comfort.
As different example, the first connector 101 be connected with backrest and the second connector 102 be connected with chair backrest can exchange.Namely the first connector 101 be connected with backrest can be connected with chair backrest 3, and the second connector 102 be connected with chair backrest can be connected with back 2.Effect is identical.
Shown in the above and figure is only preferred embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
