ABS modified plastic seat

Abstract

The invention relates to the field of seats, in particular to an ABS modified plastic seat. The ABS modified plastic seat comprises a supporting rod, a bottom plate, a base, a backup plate, an armrestmechanism, a back cushion mechanism, a knob, a screw rod, a back cushion main body, a rotating rod, a first gear, a second gear, a sliding block, an adjusting mechanism, a pedal, a through pipe, an air cushion, an air bag and an air pipe. The beneficial effects of the invention are that: a passenger can manually rotate the knob, the knob rotates to drive the rotating rod to rotate, the rotating rod drives the screw rod to rotate, and the screw rod rotates to drive a sliding block to generate a rotating trend; however, the sliding block is limited by the backup plate, the sliding block can only continuously slide up and down in the backup plate, and the sliding block slides to drive the back cushion main body to continuously move up and down, and when the back cushion main body moves to apart perfectly supporting the back of a passenger, the passenger can stop rotating the knob, so that the back cushion main body conveniently pushes against and massages the back of the passenger during use, back muscles of the passenger are relaxed, and riding fatigue is reduced.

Description

technical field [0001] The invention relates to the field of seats, in particular to an ABS modified plastic seat. Background technique [0002] ABS plastic is a terpolymer of acrylonitrile, butadiene, and styrene monomers. The relative content of the three monomers can be changed arbitrarily to make various resins. ABS has the common properties of the three components, so ABS plastic is a "tough, hard, rigid" material with easy-to-obtain raw materials, good comprehensive performance, low price, and wide application. In particular, ABS modified plastics have been widely used in machinery, electrical, textile, automobile, aircraft, ships and other manufacturing industries and chemical industries, such as seats on buses, which are usually made of this material. [0003] However, when the ABS modified plastic seat on the traditional bus is actually used, because the texture of the seat is relatively hard, the back of the passenger is always in conflict with the hard backboard ...

AI Technical Summary

Problems solved by technology

[0003] However, when the ABS modified plastic seat on the traditional bus is actually used, because the texture of the seat is relatively hard, the back of the passenger is always in conflict with the hard backboard during a long ride, and cannot be moved. It will lead to muscle stiffness and make passengers uncomfortable; at the same time, different passengers have different leg lengths, and the height of traditional seats is always the same, so it is not easy to relax the legs of all passengers
