Abstract
The invention relates to an airbag door which covers a seamless type passenger-side airbag of an instrument board of an automobile. The airbag door is arranged at a spreading port of an airbag module of an instrument board framework, and comprises a surface layer, a middle foaming layer and a reinforcing layer from outside to inside in sequence; the reinforcing layer is soft material layers laminated together; the soft material layers are made of high-density nylon; and the airbag door is provided with a Y-type weakening line. When the airbag explodes, the airbag door is opened from the middle part along the weakening line; the surface of the instrument board is torn; the middle foaming layer is also torn; but a part of the nylon fabric layer connected with the instrument board framework is not turned over. As the nylon fabric layer replaces a traditional rigid reinforcing piece, the weight of the airbag door is greatly reduced; and the surface quality is high so as to reduce the opening force of the airbag door and not to damage windshield glass.
Description
Technical field
The present invention relates to a kind of air bag doors, specifically, relate to a kind of gasbag door for covering Automobile instrument gapless passenger side air bag.
Background technology
At present, occupant side at Automobile instrument all disposes safety air bag usually, and increasing automobile type configuration gapless safety air bag, general air bag cover plate and the integrated setting of instrument carrier panel, can be with the indentation of easily tearing of in advance reduction formation at instrument panel surfaces, when the air bag explosion, the pressure that air sac bag body launches makes on the instrument carrier panel indentation tear, and air bag cover plate is opened.
Seamless airbag door commonly used roughly is divided into plastic gas bag door and metal bellows door at present.The plastic gas bag door is generally the independent weld parts of employing TPO material to the H type air bag door system of instrument board framework.Its advantage is that technology maturation is reliable, and presentation quality is good; Be difficult for smashing air regulator.But shortcoming is to satisfy the requirement of OOP (dummy's crash standards), and need to carry out laser weakening, and cost is higher, thereby less application in the foaming part.It is liner that the metal bellows door generally adopts the hard reinforcement such as iron plate, and riveted joint or in-mould injection are to instrument board framework; Or directly with iron gate solid air bag door system.Its advantage is that crippled mode is various, and technology maturation easily satisfies the requirement of OOP.But it is large that shortcoming is weight, requires a high expenditure of energy to solve the problem of glass crushing.
Summary of the invention
The object of the invention is to, a kind of low weight is provided, low tensile force, great surface quality satisfies the OOP requirement, and can not damage windshield, does not need special reduction, can improve the air bag doors that Automobile instrument gapless passenger side air bag launches safety.
In order to achieve the above object, technical scheme of the present invention is as follows:
A kind of air bag doors is installed in the deployment opening place of the air bag module of instrument board framework, comprises successively from outside to inside skin covering of the surface, foamed interlayer and enhancement Layer, and described enhancement Layer is soft material layer laminated together.
This soft material layer is the high density nylon cloth, is connected on the airbag deployment opening instrument board framework on every side.This high density nylon cloth is net structure.
The surface of described nylon cloth has coating, and described coating is polytetrafluoroethylene or PVC.
The upper surface of described coating or upper and lower surface have one deck sealant simultaneously.
Described air bag doors is provided with line of weakness.The trajectory shape of described line of weakness is the Y type.
The part of described line of weakness on the soft material layer, directly being made into by the low-intensity cotton thread.
When air bag popped, described air bag doors was opened from the centre along line of weakness, and instrument panel surfaces is torn, and middle foaming layer is also torn thereupon, but the part that the nylon layer of cloth is connected with instrument board framework is not overturn.
Owing to having replaced traditional hard reinforcement with the nylon layer of cloth, greatly reduce air bag doors weight, surface quality is high, the tensile force of air bag doors is reduced, and can not damage windshield.
Description of drawings
Fig. 1 is the cross sectional view of air bag doors of the present invention;
Fig. 2 is that air bag doors of the present invention is installed in the schematic diagram on the instrument carrier panel, there is shown Y shape line of weakness track;
The specific embodiment
Below in conjunction with accompanying drawing, do detailed description to of the present invention for the air bag doors that covers automobile passenger side gapless air bag, enable to understand better function of the present invention, characteristics.
As depicted in figs. 1 and 2, air bag doors 1 of the present invention, be installed on the skeleton 2 of instrument carrier panel 6 upper gasbag deployment openings part, the deployment opening 11 that the air bag module (not shown) is arranged on instrument board framework is fixed on the skeleton 2 with the bolt (not shown) afterwards and at the edge of deployment opening 11.Air bag doors 1 comprises soft skin covering of the surface 3, foamed interlayer 4 and as the soft material layer 5 of enhancement Layer, in the present embodiment, this soft material layer is nylon cloth.This nylon cloth is to have certain thickness cancellated high density nylon cloth to have enough intensity to guarantee nylon cloth.
The edge of nylon layer of cloth is connected with instrument board framework, and is preferred, bonding with glue.Also directly injection moulding connects.
Because nylon layer of cloth and instrument board framework bonding are fixing, the contacted part of nylon layer of cloth and instrument board framework can not overturn when airbag-releasing, still remain on closely on the skeleton, thereby when guaranteeing airbag-releasing, air bag doors can be not whole fly away, actv. has been controlled the size of airbag-releasing power, improves the safety of air bag explosion.And because nylon cloth is cancellated soft material, in airbag-releasing, have good energy-absorbing function in the process, realize " soft landing ", avoid intense impact.
Better, in nylon layer of cloth and foamed interlayer 4 adjacent surface coating polytetrafluoroethylene (Teflon) or PVC coating, its effect is to prevent that in process of production foam from escaping from.And on the coating of Teflon, can also add again one deck sealant, thereby further prevent to reduce as far as possible weight, reducing thus the air bag doors tensile force in the foaming layer infiltration nylon cloth.
The upper surface of nylon layer of cloth is foaming layer and skin covering of the surface, in the situation that seamless gasbag, the epidermis of air bag doors and the epidermis of instrument carrier panel are one, and are provided with in advance line of weakness 7.
In the present invention, directly be made into low intensive cotton thread at air bag doors line of weakness 7 position soft materials, other parts are high-intensity nylon cloths, because the intensity of cotton thread is lower than nylon cloth, the track of cotton thread part namely can be used as the line of weakness of air bag doors.
As shown in Figure 2, the trajectory shape of described line of weakness 7 is the Y type, and during airbag deployment, air bag doors therefrom mind-set peripheral direction is opened.This Y-shaped structure at first concentrates on the center-point bursting force, and air bag is more easily broken through and opened.
Described nylon cloth also can be made by other artificial or natural fiber material such as canvas.
Described nylon cloth lower surface also can apply polytetrafluoroethylene (Teflon) or PVC coating and sealant, until the part that the nylon layer of cloth is connected with instrument board framework, with antiseep.
Line of weakness can be by various common crippled modes such as laser weakening or cryoprobes.
The above; it only is preferred embodiment of the present invention; be not to limit scope of the present invention, i.e. every simple, equivalence of doing according to claims and the description of the present patent application changes and modifies, and all falls into the claim protection domain of patent of the present invention.
