Seamless gasbag door commonly used at present roughly is divided into plastic gas bag door and metal bellows door.The plastic gas bag door is generally the H type air bag doors system that the independent part that adopts the TPO material is welded to 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 carry out the laser reduction, and cost is higher, thereby less application in the foaming part.It is liner that the metal bellows door generally adopts hard reinforcement such as iron plate, and riveted joint or in-mould injection are to instrument board framework; Or directly with the solid shape air bag doors system of iron gate.Its advantage is that crippled mode is various, and technology maturation satisfies the requirement of OOP easily.But it is big that shortcoming is a weight, requires a high expenditure of energy to solve the problem of glass crushing.
Summary of the invention
The objective 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 of Automobile instrument gapless occupant side airbag deployment 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 skin covering of the surface, foamed interlayer and enhancement Layer from outside to inside successively, and described enhancement Layer is a 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 a 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, the instrument carrier panel epidermal laceration, 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 replaced traditional hard reinforcement with the nylon layer of cloth, greatly reduce air bag doors weight, the surface quality height reduces the tensile force of air bag doors, 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 scheme drawing on the instrument carrier panel, there is shown Y shape line of weakness track;
The specific embodiment
Below in conjunction with accompanying drawing, the air bag doors that is used to cover automobile passenger side gapless air bag of the present invention is done detailed description, 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 air bag module (figure does not show) is arranged on instrument board framework is fixed on the skeleton 2 with bolt (figure does not show) 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 a 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 the skeleton closely, thereby when guaranteeing airbag-releasing, air bag doors can not fly away by single-piece, 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.
Preferable, 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 one deck sealant again, thereby further prevent to reduce weight as far as possible, to reduce the air bag doors tensile force thus in the foaming layer infiltration nylon cloth.
The upper surface of nylon layer of cloth is foaming layer and skin covering of the surface, and under the situation of seamless gasbag, the epidermis of air bag doors and the epidermis of instrument carrier panel are one, and are provided with line of weakness 7 in advance.
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 promptly 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 shape structure at first concentrates on the center-point bursting force, and the easier breakthrough of air bag is opened.
