Seat backrest suspension device with hook

Abstract

A seat backrest suspension device with hook comprises a device shell composed of two plastic coated steel wires with plastic coated layers, a plastic pipe between the plastic coated steel wires, a plurality of horizontal steel wires wound on the plastic coated steel wires according to a certain distance and passing through the plastic pipe. The horizontal steel wires form steel wire knotting segments at the winding part of the plastic coated steel wires and the horizontal steel wires between the plastic coated steel wires form steel wire waving segments and the outer ends of the horizontal extension parts of the horizontal steel wires are folded into hooks. Compared with the like products, the weight of the products is reduced by half and the cost is saved by half, the products have higher performance price ratio, stronger flexibility, increased comfort, obviously reduced seat thickness.

Description

technical field [0001] The invention relates to a seat back suspension device with a hook. Background technique [0002] The steel wire suspension system used on the existing motorcycle seat can realize the cushioning of the seat and the backrest of the motorcycle seat. Such suspension system is usually suspended on the metal seat frame. Bent, also use die stamping forming bending, and a certain heat treatment), these steel wires are connected to each other by metal fasteners to form a whole. Usually the diameter of the steel wire ranges from φ2.9 to φ3.8, and its typical characteristics are: many steel wire parts, long processing route (from steel wire to forming and heat treatment to assembly), heavy weight (usually greater than 0.5kg) , the price is higher, and at the same time, due to the relative sliding between the steel wire and the steel wire, a certain amount of friction will be generated; in order to meet a certain static strength, the steel wire is usually set th...

AI Technical Summary

Problems solved by technology

Usually the diameter of the steel wire ranges from φ2.9 to φ3.8, and its typical characteristics are: many steel wire parts, long processing route (from steel wire to forming and heat treatment to assembly), heavy weight (usually greater than 0.5kg) , the price is higher, and at the same time, due to the relative sliding between the steel wire and the steel wire, a certain amount of friction will be generated; in order to meet a certain static strength, the steel wire is usually set thicker, so it is harder in the contact area of ​​the human body, in order to avoid high hardness. Reduced comfort and usually thicker seat foam, which increases the cost of the foam and reduces the available space in the car interior
