Abstract

The utility model discloses a damping chair used for vehicles in running. The utility model is characterized in that the chair is provided with an airbag damping device. The device comprises two airbag bags arranged correspondingly; a damping leaf and a gauze screen are held between the two bags; the two bags are sealed through pressing plate screws; the bags are filled with air. When the vehicle runs on an uneven highway and generates up and down jounce, the jounce can cause the pressed bag at the upper part to bear increased force suddenly, and the force compels the air in the pressed bag to flow into a bumping bag; when the force disappears, the air in the bumping bag begins to return to the pressed bag; at this time, the air flowing to the pressed bag is restricted, so that the pressed bag can not bounce quickly to play the function of damping consequently.

Description

Shock-absorbing seat in one

The utility model relates to a kind of seat, especially for a kind of shock-absorbing seat on the driving vehicle.

In technique known, the seat of driving vehicle generally adopts the seat of spring loaded or foam type, its bounce of the seat of spring loaded is big, bounce-back speed is fast, particularly when vehicle travels in the place of pavement conditions difference, the road surface of jolting often makes the people feel to have the prominent sense of discomfort that goes up under dashing forward, and fast bounce-back speed also very easily makes the people produce fatigue phenomenon.Also there is similar problem in the foam type seat.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of bounce-back speed slow, a kind of seat that vibratory sensation is little.

The purpose of this utility model can reach by following measure, and this seat is made up of the seat cushion that carriage, backrest, foam sponge and hard plate constitute.Be characterized in seat, being provided with an air bag shock absorption device, this device comprises two airbags, top is the pressurized bag, the bottom is a cushion pocket, the centre accompanies a damping page or leaf and a gauze, be provided with the hole, garden of a ventilation in the centre of damping page or leaf, center by the hole, garden has cross joint-cutting, form four elasticity page or leaf sheets, the pressurized bag is relative with cushion pocket and put and snap together, their sealings are tightened up and will be full of gas in the bag with pressing plate and screw, be entrapped on the carriage of seat then and be positioned at the bottom of seat cushion.Produce when pitching when travelling on the highway of vehicle in injustice, this jolting can make the pressurized bag bear a power that increases suddenly, this power forces the gas of pressurized bag to flow into cushion pocket, gas volume reduces in the pressurized bag, air pressure increases, air-flow is pushed 4 elasticity page or leaf sheets of damping page or leaf open, the inflow cushion pocket that gas is without hindrance, when the power that increases disappeared, stressed bag gaseous tension reduced, cushion pocket gas returns the pressurized bag, at this moment, the elasticity page or leaf sheet of damping page or leaf is subjected to the prevention of gauze and closes, and gas can only flow into the pressurized bag from limited aperture in the middle of the damping page or leaf, thereby the bounce-back speed of the pressurized bag that slowed down has played cushioning effect.

Utilize accompanying drawing, the utility model is further described.

Figure one is the utility model External view;

Figure two is the A-A section-drawing of figure one;

Figure three is the front view of airbag;

Figure four is the birds-eye view of figure three;

Figure five is the damping page or leaf;

Figure six is a gauze;

In figure one and figure two, the shock-absorbing seat that foam sponge (8), hard plate (9) and air bag shock absorption device are formed has been described by carriage (12), backrest (11).Pressurized bag (1) in the air bag shock absorption device, the material of cushion pocket (10) and damping page or leaf (3) is made by elastomeric material, and gauze (2) can be a wire netting, also can be other metal gauze.Two sacks are outwards outstanding, and have and be used for the periphery that fit sealing is used, (referring to figure three and figure four), periphery is provided with and is used for coupled fasteners, damping page or leaf (3) is respectively equipped with corresponding fastener hole with gauze (2) top, gauze (2) is positioned at the top of damping page or leaf (3), the two is clipped in the middle of the airbag, with pressing plate (6) and screw (5.7) their sealings are tightened up, gas will be full of in the bag, pattern by figure one is entrapped in the air bag shock absorption device that assembles on the carriage (12) then, puts the seat cushion that hard plate (9) and foam sponge (8) are made above, so just constitutes a kind of seat with shock absorption device.

According to the shock-absorbing seat that such scheme is made, characteristics such as it is little to have a vibratory sensation, and bounce-back speed is slow, and the seat sense is comfortable, this seat with shock absorption device is specially adapted to use on the Pullman saloon applicable to any driving vehicle.

Claims
