Abstract
The utility model discloses a backrest grid of an automobile seat. The backrest grid of the automobile seat comprises an outer frame steel wire, horizontal steel wires, a connecting steel wire and an elastic plastic tube. The backrest grid of the automobile seat is characterized in that longitudinal steel wires are further laid on the horizontal steel wires. The connecting points of the horizontal steel wires and the longitudinal steel wires are connected through connecting seats, and the connecting seats are provided with cross-shaped steel wire clamping positions. Grooves are formed in the lower portions of the connecting seats, springs are arranged in the grooves, the springs are arranged to be exposed into the grooves through clamping connection, the connecting steel wire is arranged on the two sides of the outer frame steel wire in a winding mode, and bent hooks are arranged at the front ends of the connecting wire. A certain angle is formed between the connecting steel wire and the outer frame steel wire, and the outer frame steel wire is made of a plastic-coated steel wire. The backrest grid of the automobile seat solves the problem that a backrest is too hard or insufficient in elasticity, is good in elastic efficiency, delays spine ageing, provides comfort degrees for drivers and passengers, and reduces waist stress.
Description
Technical field
The utility model relates to the improvement invention in a kind of vehicular spare parts field, relates in particular to a kind of improvement invention of motor vehicle seat back grid.
Background technology
Motor vehicle seat back adopts hard backboard substantially at present, re-lays the soft foam that is applicable to human body back curve.Automobile long-time running is jolted, and foam follows the string, thereby accelerates the fatigue of human body back muscle, more easily causes damage or the bending of back vertebra.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of motor vehicle seat back grid with spring function is provided.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to realize: this kind of motor vehicle seat back grid, include housing steel wire, transverse steel wire, connect steel wire, elastoplast pipe, described transverse steel wire is concavo-convex alternate bending setting, on described elastoplast pipe, be evenly arranged aperture, described transverse steel wire is located in aperture, described transverse steel wire is connected with housing steel wire both sides, it is characterized in that: in described transverse steel wire, be also equipped with longitudinal steel wire, transverse steel wire is connected by Connection Block with the each interface point of longitudinal steel wire place, described Connection Block is provided with criss-cross steel wire clamping position, groove is offered in described Connection Block bottom, in described groove, be provided with spring, described spring is revealed and is located in groove by clamping, the winding of described housing steel wire both sides connects steel wire, the front end of described connection steel wire is provided with crotch, described connection steel wire and housing steel wire are angled, described housing steel wire adopts plastic coating steel wire manufacture.
Described connection steel wire becomes 60 degree angles with housing steel wire.
Described Connection Block is cylinder, and its underpart groove is cylindrical groove.
The beneficial effects of the utility model are that the motor vehicle seat back cellular structure after improving is reasonable, easy to use, are applicable to various sitting posture occasions; Provide large area to support to driver and conductor's waist and backbone, traveling comfort is good, reduction is tired, and backbone is played a protective role.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of Connection Block in the utility model.
Fig. 3 is the birds-eye view of Connection Block in the utility model.
The specific embodiment
Accompanying drawing has represented structure of the present utility model, further illustrates by reference to the accompanying drawings its details below again.This motor vehicle seat back grid, include housing steel wire 5, transverse steel wire 3, connect steel wire 1, elastoplast pipe 6, described transverse steel wire 3 is concavo-convex alternate bending setting, on described elastoplast pipe 6, be evenly arranged aperture, described transverse steel wire 3 is located in aperture, described transverse steel wire 3 is connected with housing steel wire 5 both sides, in described transverse steel wire 3, be also equipped with longitudinal steel wire 2, transverse steel wire 3 is connected by Connection Block 4 with the each interface point of longitudinal steel wire 2 place, described Connection Block 4 is provided with criss-cross steel wire clamping position, groove is offered in described Connection Block 4 bottoms, in described groove, be provided with spring 7, described spring 7 is revealed and is located in groove by clamping, described housing steel wire 5 both sides windings connect steel wire 1, the front end of described connection steel wire 1 is provided with crotch, described connection steel wire 1 is angled with housing steel wire 5, described housing steel wire 5 adopts plastic coating steel wire manufacture, 5 one-tenth 60 degree angles of described connection steel wire 1 and housing steel wire, described Connection Block 4 is cylinder, and its underpart groove is cylindrical groove, matches with spring, facilitates clamping, saves material.
In the utility model, housing steel wire 5 with transverse steel wire 3, be connected steel wire 1 and be fastened; Elastoplast pipe 6 can play overall resilience and playback effect and keep the distance between transverse steel wire 3 to make it not yielding transverse steel wire 3, and can not affect the traveling comfort of backrest; Connect steel wire 1 front end and be provided with crotch subsidiary certain angle, make user can directly articulate assembling, and this angle is preferably 60 degree angles, connect steel wire 1 and be inclined upwardly, while use, articulate tolerances large after articulating, backrest is difficult for moving down, and can not be difficult to because of angle too small articulate; Longitudinal steel wire 2 be arranged so that backrest grid is stressed more even, meet the stressed standard of mechanics; In the criss-cross clamping position on longitudinal steel wire 2 and transverse steel wire 3 difference Snap joint seat 4 surfaces, Connection Block 4 bottoms are provided with spring 7, and spring 7 other ends can be inconsistent with back board, and arranging of spring 7 improved elasticity, the comfort level of grid, and make grid stress equalization, increase the service life.
