Abstract

The utility model relates to the improvement of the structure of a vehicle seat, which is composed of a supporting frame, a seat pad, and a backrest, wherein, the seat pad is tied to the inner side of a seat pad frame, and is fixedly provided with a brace rod which is provided with a plurality of pull rings. An elastic surface on the brace rod is composed of a plurality of plane extension springs which are sheathed on the pull rods. Consequently, the utility model has the advantages of simple structure, reasonable structure, flat integral surface, no burr, high durability, good elasticity, etc. The utility model is especially suitable for serving as a vehicle seat for a farm vehicle.

Description

Auto use chair

The utility model relates to a kind of seat, especially to a kind of structural improvement of automobile-used seats such as automobile, farm vehicle.

Travel in the various road conditions because vehicles such as automobile, farm vehicle are everlasting, chaufeur is easy to fatigue because of jolting, and causes discomfort.In order to improve driver working environment, the shock resistance of auto use chair is concerned by people always.For example, the utility model patent (patent No. 86206222) of a kind of " auto use chair " by name is made up of backrest and seat cushion two parts.Seat cushion and backrest are metal framework, and are the netting structure.Sponge or foamed plastic and artificial leather or fabric overcoat can freely take off.Its advantage be car under steam, the vibrations that passenger and driver are subjected to reduce, and after overcoat takes off, are beneficial to circulating air, make the people feel comparatively nice and cool.But, take a lot of work and easily relax, so appreciiable auto use chair still adopts the conventional confguration that adds sponge and overcoat on spring seat cushion because of netting canopy system difficulty.Because this spring adopts flush type extension spring, and canopy is tightly fixing with iron wire etc. on cushion frame.So processing and fabricating is more time-consuming, surface irregularity and influence its fixedly fastness and service life.

The purpose of this utility model provides a kind of rational in infrastructure, making, easy to assembly, with low cost, and good springiness is taken advantage of the comfortable auto use chair of seat.

Another purpose of the present utility model provides a kind of smooth, burr free of spring face of seat cushion, and damping property is good, and long-lived auto use chair.

Major scheme of the present utility model is: be fixed with strut in described cushion frame inboard, which is provided with some draw rings, described elastic surface is made of the some plane extension springs that are nested with on draw ring.Usually the two ends of every extension spring are respectively fixed by a draw ring institute hook.

For planarization and the fastness that improves the seat cushion elastic surface, can on described strut, be flat ring-type by sheathed draw ring; Be distributed with several fixed contacts between strut and the cushion frame, and draw ring is isolated, it is spacingly moved in two fixed contact intercropping.Wherein, distance doubly is advisable for the 1.5-5 of draw ring wall thickness between described strut and the cushion frame; Distance doubly is advisable for the 1-1.8 of S shape plane extension spring width between described two fixed contacts.So that plane extension spring layout density and elasticity are more suitable, structural strength is higher.In addition, can to adopt width be that the thin-walled iron pipe of 15-25mm slightly flattens up and down or adopts band iron to bend and be welded into the flat ring and constitutes to draw ring.

Therefore, the utlity model has simple and reasonablely, easy to make, easy for installation, firm, seat cushion is smooth, good springiness, and characteristics such as anti seismic efficiency is good, and is durable in use can be used as auto use chair, especially are suitable for the auto use chair of making farm vehicles such as trac..

Fig. 1 is a kind of structural representation with local section of the present utility model.

Fig. 2 is a kind of seat cushion elastic surface in the utility model and the structure for amplifying scheme drawing of framework.

Below by embodiment, the utility model is specified.

Cushion frame 2 is to adopt steel tube bending to become U type framework, and is linked to be the sealing framework in welding, and is welded with strut 5 in the forward and backward inboard of framework, is equipped with five draw rings 4 on it.Draw ring adopts the thin-wall steel tube of Φ 19mm, blocks by the length about 20mm, slightly flattens up and down to form.The two ends of strut 5 and five equilibrium are provided with fixed contact 3 everywhere, make between strut 5 and the seat cushion 2 apart from for about 8mm.Plane extension spring 6 can adopt the 70# carbon steel of φ 4.0 to be bent into S shape, one end is nested with in draw ring 4, other end pincers are tight and use anchor clamps to stretch to the other end of cushion frame 2, move corresponding draw ring 4, with the other end of plane extension spring 6 and draw ring 4 rhampotheca mutually, loosen anchor clamps, plane extension spring 6 soon tensioning is easily fixed.After five rhizoplane extension springs 6 are fixed on cushion frame 2 successively, can slightly move the draw ring 4 of 3 of two fixed contacts, the plane extension spring is more evenly distributed.Then, on the elastic surface 1 that constitutes thus, be equipped with sponge 22, and be overmolding to seat cushion, be arranged on the backrest 7 by known technology with overcoat 21.Perhaps rely on bearing pin 24 to be installed in and be provided with on the interior frame of farm vehicle operator's compartment.All the other structures can adopt known technology, are omitted at this.

Claims
