Abstract

The nomenclature of the utility model is an air-jet cushion which belongs to the article for daily use field. The utility model is mainly used for solving the disadvantage of the ventilation gas permeation aspect of the existing similar products. The main technical characteristic of the utility model is that the utility model is a device which makes use of a relative motion between the human body and a transportation means as the driving power to carry out the local forced ventilation and cooling. The air-jet cushion is composed of an air sac (1) provided with small holes, a single way air inlet valve (2), an elastic recovery body (4), a maintaining frame (5), a surface covering, and a decorative fabric. The utility model mainly used for meeting the requirements raised by the occupants of ventilation, cooling, shock absorbing of the chairs on various transportation means.

Description

Air-jet cushion

The utility model is a kind of seat cushion that uses on transportation means (or back cushion), is specially adapted to highway transport vehicle.

The base member of taking advantage of on the general purpose hauling instrument all is made up of seat and seat, back cushion.Singly take one's seat, back cushion, traditional product often can only reach vibration damping and soft requirement; And can not satisfy when taking advantage of ventilate, the requirements at the higher level of cooling.Especially this contradiction is more outstanding when ambient temperature is higher; The contact portion of human body and seat is higher owing to making soaked with sweat with temperature, and air is difficult for circulation again, so very easily cause skin sick, also influences people's work efficiency simultaneously.

Order of the present utility model ground: will adopt a kind of force ventilated means exactly, reach the order ground that existing product fails to reach.It can prevent long-time riding public transportation means effectively; People and seat contact portion, sense of discomfort; With the cutaneous lesions that may cause.

Be achieved in that this product places between people and the seat order of the present utility model, when jolting in vehicle is advanced makes human body and seat produce relative motion, will produce seat, or the variation of back cushion pressure.When pressure hanged down, the air bag in the pad is by its inner set recovery of elasticity body, and was air-breathing by the aperture of check valve and balloon surface.When pressure was high, the gas in the closed check valve, air bag just gave the aperture ejection that designs earlier by balloon surface.Thereby reached local airiness and cooling effect.

The utility model is also considered the human body of taking transportation means owing to utilized inevitable the jolting in the transportation means dexterously as the part in the transportation means system, utilize inevitably relative motion between them, has designed this product.This product can be aeration-cooling, can play certain buffer action again.Thereby further having reduced vehicle jolts to occupant's influence.

Enforcement one example and the concrete structure of utility model are such, please refer to accompanying drawing:

Sequence number 1 is the main body air bag that constitutes Air-jet cushion among the figure, and it is to be bonded by the airproof fabric that a kind of single face is coated with rubber, plays a kind of air chamber in use of the present utility model.Sequence number 2 is breather cheek valves, and it is the body by plastic injection-moulded one-tenth, and the polyester flake of drawing combines, and is the main free air diffuser in the utility model work.Sequence number 3 is stamping forming apertures on a given side of sequence number 1 according to certain rules, is main exhaust spray orifice in the course of the work.Sequence number 4 is the recovery of elasticity bodies by certain thickness sheet rubber hot-forming (or by rubber injection mold moulding), and it can make air bag have air-breathing function in the course of the work.Sequence number 5 is the maintenance frames that formed through welding, polishing by the steel wire of diameter 2mm, and its function is to make the utility model that a kind of attractive in appearance, smooth profile be arranged.And the unillustrated dressing of a surface fabric of accompanying drawing, its function mainly plays decoration function and improves tactility.

Claims

1, the relative motion that can utilize means of delivery and human body is as power, pulvilliform ventilation, cooling, shock attenuation unit, and this device main body is one and is made by gastight material; Have aperture (3) on its certain surface; Recovery of elasticity body (4) is equipped with in inside; The air bag (1) of breather cheek valve door (2) is housed again on a certain position.
