Description

The automobile side impact occupant protection system

When the utility model relates to a kind of automobile and bumps, the device that occupant's side is protected.

At present, be installed in the anti-side collision safety device in the automobile, all be when automobile bumps; send signal by crash sensor; light the seed material that is arranged in the air bag gas generator, produce a large amount of gases and make airbag aeration expand, open, thereby play protection passenger's purpose.More than device be owing to must establish gas generating unit in the pneumatophore, thus weak point be complex structure, cost is higher and only be disposable use.

But the purpose of this utility model provides the automobile side occupant protection system that any gas generating unit need not be set in a kind of repeated use and the pneumatophore.

The purpose of this utility model is achieved in that the air bag that comprises inflatable, and it may be folded on below the roof hoard under the on-inflatable deployed condition.The S. A. of the forward and backward fork that will be wrapped in by pneumatophore be arranged on the affixed bearing of roof frame in, an end is set on the S. A. of fork is fixed on the bearing, the retracing spring that the other end contacts with the swing part of fork.Link to each other with crash sensor and be fixed in electromagnet on the roof frame, the affixed lock pin that contacts with the front roll bar bottom surface of its front end.One end of front roll bar S. A. is provided with the postive stop baffle of back fork, and pneumatophore is provided with a Non-return air valve.

Adopt said structure, before being wrapped up by pneumatophore, back fork, with pneumatophore be set in place foldedly near roof frame before, between the back fork, when automobile bumps, crash sensor sends signal, make the electromagnet energising that is attached thereto, drive lock pin and the front roll bar bottom surface disengaging affixed with the electromagnet front end, front roll bar is with the rotating shaft clickwise under the effect of retracing spring, the back fork postive stop baffle that is arranged on rotating shaft one end also together changes down with the rotating shaft cw, make under the back fork changes with the rotating shaft conter clockwise under action of reset spring, pneumatophore is supported expansion, because at this moment in the pneumatophore, exist air pressure difference outward, impel outside air to enter in the pneumatophore, pneumatophore is expanded in the body by the Non-return air valve that is arranged on pneumatophore, external pressure is identical.Therefore can realize need not establishing any gas generating unit in the pneumatophore; When automobile bumps the occupant is protected, use is opened Non-return air valve by external tool after finishing, and gas in the air bag is emitted, and after folding again, this device is reverted to initial condition, but so repeated use.

As further improvement of the utility model, affixed one storage tank that links to each other with crash sensor and communicate with pneumatophore by the ventilation flue on roof frame.After adopting this structure, when automobile bumped, crash sensor sent signal, and the electromagnetic valve that is positioned at the storage tank mouth is opened, because pressure reduction charges into gas in the jar rapidly in the pneumatophore that has launched, made the rapid inflation of pneumatophore.

In sum, the utility model has the advantages that: simple in structure, cost is low, any gas generating unit need be set in pneumatophore, in the time of just can being implemented in automobile and bumping the occupant is carried out lateral protection.

The utility model is described in further detail below in conjunction with drawings and Examples.

Scheme drawing when Fig. 1 is the utility model automobile side impact occupant protection system airbag deployment.

Fig. 2 is the structural representation of the utility model automobile side impact occupant protection system.

Fig. 3 is the birds-eye view behind the dismounting roof frame shown in Figure 2.

As shown in Figure 1; the utility model automobile side impact occupant protection system has air bag 1; by pneumatophore be wrapped in mould the system forward and backward fork 2,3; be fixed in bearing 5 on the roof frame 11 by screw; steel S. A. 4 and the interior a pair of ball ball-bearing casing interference fit of bearing 5 axis holes, and forward and backward fork (shows as Fig. 3) by coaxial being fixed on the steel S. A. of screw.Be welded on edge one side of bearing 5 at outside socket one end of forward and backward fork and rotating shaft coaxle part, the steel helical torsional spring 6 that the other end contacts with the swing arm of forward and backward fork, electromagnet 12 front ends that are fixed on the roof frame 11 by screw weld a lock pin 7 that contacts with the front roll bar bottom surface, and electromagnet links to each other (showing as Fig. 2) with crash sensor in the car.End at the front roll bar S. A. is welded with the postive stop baffle 9 that contacts with back fork bottom surface, and pneumatophore is bonded with a Non-return air valve 8.

Show as Fig. 2, when automobile bumps, send signal by crash sensor, electromagnet energising drives the lock pin 7 that is welded on its front end and breaks away from front roll bar 2 bottom surfaces, under the elastic force effect of helical torsional spring 6, make front roll bar with its affixed S. A. clickwise, the swing arm bottom, the postive stop baffle 9 that is welded on the back fork 3 of S. A. 4 one ends this moment together changes down with S. A., and under the elastic force effect of back fork helical torsional spring 6, back fork is accommodated with the rotating shaft conter clockwise.Before, the swaying direction of back fork and vehicle body side parallel sidewalls (showing) as Fig. 1, at this moment the supported expansion of pneumatophore, because in the pneumatophore, exist air pressure difference outward, outside air enters in the air bag by Non-return air valve 8, airbag aeration is opened, if this moment the passenger head with the collision movement of car body during extruding gasbag, gas in the air bag is closed Non-return air valve, make and keep a part of gas in the pneumatophore, thereby given cushion effect to human body head, avoid the collision of human body head and in-vehicle apparatus, after this time using, use needle tubing gas in the air bag to be emitted, before inciting somebody to action again by Non-return air valve, back fork resets, before simultaneously airbag fold being placed on, between the back fork so that use next time.

As further improvement of the utility model, the affixed storage tank 10 that links to each other with crash sensor and communicate with air bag 1 body by the ventilation flue on roof frame 11.When automobile bumps; the electromagnetic valve that the signal that is sent by crash sensor will be positioned at jar mouthful is opened; in airbag deployment, in pneumatophore, inflate, make the open process of airbag aeration rapider, thereby more help protection occupant's head by the ventilation flue.

The utility model can not need that any gas generating unit is set in pneumatophore can be implemented in collision process In prevent that human body head and in-vehicle apparatus from bumping, and after once using, can again this device be resetted with For using next time, have characteristics simple in structure, that cost is low.
