Abstract

The invention relates to a gasbag-type waist support and headrest cover for a car. A waist gasbag and a headrest gasbag can be charged. The invention has the functions as follows: on one hand, when leaning against a charged headrest via the head, a driver can drive without any influence and does not feel tired on the waist and the neck; and on the other hand, if the head of the driver is snapped back by inertia in a front crash, the damage to the head and the neck can be reduced because of the touch of the head and the gasbag.

Description

Waist holder of automotive airbag formula and headrest overcoat

Technical field

The present invention relates to a kind of car accessories, its function is to prevent chaufeur drive for a long time fatigue be easy to get lumbar vertebra disease and cervical spondylopathy, and another function is when preventing that the place ahead from colliding, head part's strength of rebounding is bigger, easily make head and neck injured, have this air bag can realize the head soft landing, alleviate injury.

Background technology

At present, headrest on the global automotive seat mobile motorized that all do not realize in the horizontal direction, all be that armrest goes to move or presses its level is moved forward or backward, be against on the headrest more comfortable to reach the people's neck when driving that adapts to various statures, also the someone has made some square pockets, the material that adds of the elastomeric space wadding of some softnesses or polyurethane foam and so on is loaded onto in the inside, square pocket is sticked out, on the cooresponding position of the neck of pad before headrest, so that neck is more comfortable, in addition there is not other better way.For the traveling comfort of lumbar vertebrae, luxury car has had the electronic jack-up retracting device of backrest waist, and does not also have on the low and middle-grade car, is not just indicating needs.

Summary of the invention

Technical matters to be solved by this invention be can make the corresponding people's hindbrain part of headrest institute can be after inflation projection, and energy and people's back brain is close together, and the sight line when not influencing the people and driving, sleepy in order not cause the long-term easily generation of driving at a high speed of people, the spy is furnished with computer control, when the speed of a motor vehicle was higher, time-delay was with the air bags withdrawal of projection, and the time-delay inflation is protruding during low speed driving.In order to make the driver comfortable, waist at backrest is provided with a plurality of air bags, and its purpose one is different because of driving people's height height, and the lumbar vertebrae position is different and prepare, another purpose is in order to make inflation and the venting in turn under computer control of a plurality of air bags, to reach the effect that lumbar vertebra is equivalent to massage.

Its technical scheme is the outside at the headrest core, the inside of headrest overcoat is provided with an air bag, when air bag is heaved, the lower part is higher, a special soft projection is placed between the lower head pillow and air bag of headrest, be more suitable for like this contacting with bossing in people's hindbrain, in order to give airbag aeration and exhaust, air pump and inflation have been set up, exhaust solenoid valve, and by the computer direct control, when needs are given the headrest airbag aeration, can press the headrest gas-filled switching tube, air pump and the work of headrest inflation electromagnetic valve, gas is charged into the headrest air bag, when the position that the sensation head leans on is fit to, can stop air inlet, if think when position that head leans on exceeds, can be by the headrest air discharge cook, the headrest exhaust solenoid valve starts, and discharges unnecessary gas, till satisfaction, sleepy when preventing on express highway long-time scorch, ad hoc hypervelocity time-delay headrest air bags device in computer is when the speed of a motor vehicle surpasses certain speed, behind the certain hour, the headrest air bag is a self-bleeding, and after the air bags, the back brain that makes the people is by the overcoat of resting the head on less than air sac, avoid having an accident because of sleepy, after the speed of a motor vehicle is lower than certain speed and certain hour, according to the computer memory program, air pump and the work automatically of headrest inflation electromagnetic valve, make headrest air bag time-delay tonifying Qi, the headrest air bag is charged on the original height.

When headrest needs lifting, rotate with worm screw in the driven by motor backrest in the backrest, worm screw band worm gear rotates, being installed with the headrest lifting screw in the worm gear center screw moves up and down thereupon and drives the headrest that is fixed on the screw rod and move up and down, to adapt to the head part position of different heights, lifting screw can be made tubulose, so that electric wire and tracheae can be worn in middle hole, make electric wire and tracheae lead to backrest and down transmit, avoid being exposed from headrest.A plurality of waist holder air bags are equipped with inflation electromagnetic valve and exhaust solenoid valve before the backrest, when heaving, which air bag of needs can press corresponding inflation electromagnetic valve and air pump, press corresponding exhaust solenoid valve when needing exhaust, need heave in turn when falling, can press the massage valve, under computer control, a plurality of air bags can fill exhaust in turn, reach the purpose of massage like this.

The advantage of doing like this is to have reduced driver and crew's cervical spondylopathy and lumbar vertebra disease yield, has reduced the neck injury rate that produces driver and crew because of the front collision.

Description of drawings

Fig. 1 is a technical scheme structural principle scheme drawing of the present invention.

The specific embodiment

As shown in Figure 1, in backrest 8, be provided with the worm screw 5 of driven by motor and the worm gear 7 that worm screw 5 drives, be installed with headrest lifting screw 6 in worm gear 7 center screws, when the driven by motor worm gear pairs rotates, headrest lifting screw 6 drives headrest core 4 and moves up and down, headrest core 4 preceding bottoms are provided with soft projection 3, be provided with air bag 2 at the front upper part of headrest core 4 and the front of soft projection 3, the outside of air bag 2 is surrounded by headrest overcoat 1, headrest overcoat 1 labour contractor's pillow 4 and air bag 2 wrap in wherein entirely, in order to make air bag 2 risings and falling, headrest overcoat 1 needs to make with elastomeric material, in order to give air bag 2 inflation and exhausts, ad hoc air pump 12 and headrest inflation electromagnetic valve 10 and headrest exhaust solenoid valve 11, and all by computer 9 controls, in order to make driver's lumbar vertebrae health, ad hoc have a waist

holder air bag

16,18,21, be provided with waist holder airbag aeration

electromagnetic valve

13,17,20, be provided with waist holder

exhaust solenoid valve

15,19,22, by air pump 12 air feed, all electromagnetic valves, easily freeze in order to prevent that air humidity is big in the air bag in winter by computer 9 controls, ad hoc Thermal insulating warm mattress 14, by computer 9 controls, can make winter the driver warm, can prevent that again pneumatic element and pipeline freeze.
