The seat back suspension device is simple in structure, convenient to assembly and high in production efficiency.
Description
Technical field
The utility model relates to a kind of automotive seat parts, belongs to the seat technical field, specifically a kind of seat back suspension arrangement.
Background technology
[0002] since the reform and opening-up, particularly the Domestic Automotive Industry growth momentum is powerful in recent years, China become continue U.S., day after the 3rd automobile produce the country of breaking ten million per year, enter ten million automobile superpower ranks.
Along with the raising of individual family income, automobile has become the first-selection of present household consumption, and people propose more to pay attention to the traveling comfort of its seat the higher requirement except brand, safety and quality for automobile.
Number of patent application is: " 200910143258.6 ", the name be called: " a kind of seat back suspension arrangement with hook " in first to file, a kind of seat back suspension arrangement is disclosed, it comprises by two plastic coating steel wire component devices housings with coating layer, between the described plastic coating steel wire plastic pipe is set, some horizontal steel wires twine according to a determining deviation and are arranged on the plastic coating steel wire, and transverse steel wire is passed plastic pipe; Described transverse steel wire and plastic coating steel wire winding place form the bird caging section, and the transverse steel wire between the described plastic coating steel wire is arranged to steel wire wave section, and the horizontal expansion place outer end of described transverse steel wire is converted into hook.
Above-mentioned seat back suspension arrangement is because it adopts the horizontal expansion place outer end of transverse steel wire to be converted into this structure of hook, so in the manufacturing process of product, the comparision of production trouble of hook, production efficiency is low, simultaneously, also needs to be coupled to new production facilities and could realize mechanical automation production; In addition, mainly by linking up with to realize whole fixing, during assembling, because hook number is too many, assembling is also inconvenient for this seat back suspension arrangement.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to assembly, seat back suspension arrangement that production efficiency is high for the deficiencies in the prior art.
The purpose of this utility model is to realize like this, this seat back suspension arrangement comprises plastic coating steel wire, be arranged on the middle plastic pipe of two plastic coating steel wires, pass the many transverse steel wire that be arranged in parallel that the plastic pipe two ends are connected with plastic coating steel wire, it is characterized in that: it comprises that also a skeleton connects steel wire, the end, one end extension of described plastic coating steel wire is processed with hook, other end extension is processed with lower buckle portion, described lower buckle portion folding has twice curved, the plane A at the curved place of first is the plane that two plastic coating steel wires consist of, the plane B at the curved place of second is the perpendicular plane, plane that consists of with two plastic coating steel wires, described skeleton connect steel wire hang on first on the A of plane curved in.
Described transverse steel wire is straight structure of steel wire, and plastic pipe is passed in the centre, two ends are connected with the plastic coating steel wire knotting.
Many described transverse steel wire are by the parallel uniform interlude that is arranged on two plastic coating steel wires.
Described skeleton connects in the middle of the steel wire with a plurality of bendings, and two ends stretch out and are processed with hook, skeleton connect steel wire along axis direction with crooked radian.
Being connected between described transverse steel wire and the plastic coating steel wire is that the knotting mode by twining rear bending is connected and fixed.
The beneficial effects of the utility model are:
The utility model integral structure is simple, need not to use special production facilities, therefore can enhance productivity and reduce cost, because transverse steel wire is that straight structure does not adopt hook, namely convenient production avoided again the complexity of installing; Simultaneously by forming hook and lower buckle portion in the bending of the up and down extension of plastic coating steel wire, realized with cushion frame rationally fixing, simple in structure, intensity is high, production efficiency is high.
