Abstract
The invention provides an airbag device for protecting knees and legs, which comprises a module frame. An air bag and a decoration cover for air charging system are arranged in the module frame, and a decoration cover is arranged on the module frame. The invention is characterized in that the two secondary air chambers are symmetrically arranged at two sides of the lower part of the air bag, and a notch is provided in the middle area of the lower part of the air bag; the two secondary air chambers are respectively folded into a main air chamber at the upper part of the air bag; an isolation strip is respectively arranged between the secondary air chambers and the main air chamber. When the air charge is performed, the main air chamber arranged at the upper part of the air bag is first fully charged to ensure the protection for the knees. Then, the main air chamber is continuously charged to extend the secondary air chamber so as to prevent the legs from directly contacting with the lower part of a dashboard, thereby reducing the harm to the legs, simultaneously increasing the contact area between the legs and the knees, and protecting the legs and the knees more effectively. As the broken notch is provided in the middle area of the lower part of the air bag, the airbag is kept away from the decoration cover when being extended, thus ensuring that the air bag is extended in the required direction.
Description
Technical field
The present invention relates to a kind of knee air bag device that is provided on the automobile, particularly a kind of airbag apparatus that is used to protect knee and shank.
Background technology
Knee air bag is placed in the bottom of auto meter disc assembly, can prevent that in the head-on crash accident passenger's knee and shank are subjected to the bump of hard thing in the car, such as the bump of gauge panel bottom in the car.When bumping, the knee air bag device can be inflated in airbag by gas filled device.After knee air bag launched fully from the gauge panel bottom, knee air bag can cover the gauge panel lower surface, protection passenger's knee and shank.
Traditional knee air bag normally is made of airbag, gas filled device, module carrier and decorative cover, its expansion mode has two kinds: a kind of is that airbag fully upwards launches, because the setting height(from bottom) of module carrier is restricted, so the protection area is little, only limit to the protection of knee, can not protect shank by actv.; Another kind of airbag is to launch simultaneously up and down, when launch the bottom because the interference of decorative cover, can not be well on request direction launch; In addition,, the duration of run of upper area can not be guaranteed, therefore knee and shank can not be well protected because airbag top and lower area launch to carry out simultaneously.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists; a kind of airbag apparatus that is used to protect knee and shank is provided; this airbag apparatus can be guaranteed airbag direction expansion on request, increases the protection area of knee and shank, thereby can effectively protect knee and shank.
The present invention is achieved in that it comprises module carrier, in module carrier, be provided with airbag and gas filled device, on module carrier, be provided with decorative cover, its special character is: be provided with two secondary air chambers in airbag bottom bilateral symmetry, zone line in the airbag bottom is a breach, described two secondary air chambers fold into respectively in the main gas tank on airbag top, are respectively equipped with insulation strip between secondary air chamber and main gas tank.
The above-mentioned airbag apparatus that is used to protect knee and shank, described insulation strip are to be made by sewing thread to form or formed by adhesive tape bonding.
The above-mentioned airbag apparatus that is used to protect knee and shank, described insulation strip are to form by making through the cloth of clip.
Advantage of the present invention is: owing to be provided with two secondary air chambers in the airbag bottom, the secondary air chamber folds into respectively in the main gas tank on airbag top and by insulation strip isolates, and can guarantee that first main gas tank with airbag top is full of when inflation, at first guarantees the protection of knee; Then continue inflation the secondary air chamber is launched, prevent shank and gauge panel bottom direct contact, thereby reduce injury, strengthened the area of contact of leg and knee simultaneously shank, can more effective protection leg and knee.Because airbag bottom zone line is open circuited breach, makes airbag can avoid decorative cover upon deployment, guarantee airbag direction expansion on request.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the expansion scheme drawing of airbag among Fig. 1;
Fig. 3 is the structural representation after the secondary air chamber folds among the present invention;
Fig. 4 is the A-A cutaway view of Fig. 3.
Among the figure: gas filled device 1, module carrier 2, decorative cover 3, drawstring 4, airbag 5, main gas tank 501, secondary air chamber 502, insulation strip 6.
The specific embodiment
As shown in the figure, the present invention has a module carrier 2, is provided with airbag 5 in module carrier 2, is provided with gas filled device 1 in airbag 5, and gas filled device 1 and airbag 5 are hinged with decorative cover 3 by being bolted on the module carrier 2 on module carrier 2.Be provided with two secondary air chambers 502 in airbag 5 bottom bilateral symmetry, the zone line of airbag 5 bottoms is a breach, and described breach separates two secondary air chambers 502.Described two secondary air chambers 502 fold into respectively in the main gas tank 501 on airbag 5 tops, are respectively equipped with insulation strip 6 between secondary air chamber 502 and main gas tank 501.Described insulation strip 6 is to be made by sewing thread to form or formed or formed by making through the cloth of clip by adhesive tape bonding, and insulation strip 6 is made with sewing thread and become example in the present embodiment.In the main gas tank 501 on airbag 5 tops, be provided with drawstring 4, with the thickness of control airbag 5 expansion.
When positive side collision takes place in vehicle, gas filled device 1 is operated according to the signal of vehicle transmission, the gas of its storage inside is charged in the main gas tank 501 of airbag 5, when main gas tank 501 launches to put in place and reaches design-calculated pressure, sewing thread is by tear fracture, gas can break through insulation strip 6 and enter secondary air chamber 502, and it is launched, and the breach during inflation in the middle of the airbag bottom can be avoided the interference of decorative cover 3.Inflation back main gas tank 501 and secondary air chamber 502 are between meter panel of motor vehicle bottom and passenger's knee and the shank, thus protection passenger's knee and shank.
