Abstract
The utility model relates to a guide for unfolding car side curtain airbag, which is a tubular body formed by rectangular plates overlapping with each other on opposing edges. A guide plate is arranged on the bottom of the tubular body along the axial direction of the tubular body. One side of the guide plate near two overlapping edges is inclined downwards. The tubular body is provided with installation lugs. The guide can bear the impact force generated by the detonation of a side curtain airbag so as to prevent damage of car interiors and guide the side curtain airbag to unfold and prevent the side curtain airbag being hooked by interior plates, thereby ensuring the side curtain airbag expanded out from the inner liner of a top cover and the interior plates.
Description
Technical field
The utility model relates to the parts in the car side airbag device, particularly a kind of car side inflatable curtain deployment guide.
Background technology
Along with the pay attention to day by day of people to automotive safety, increasing car begins to equip the side gas curtain, the side gas curtain is installed in body side wall and the top cover liner, when vehicle generation side collision, the side gas curtain is gone out in car roof liner and trim panel, form soft air cushion, the bump between buffering occupant and the interior trim, thus reduce the injury that the occupant is caused.
The side gas curtain can produce very strong impulsive force in the expansion process that detonates, may smash trim panel and produce splash, also may be tangled by trim panel simultaneously, causes airbag normally to launch, influence protection effect.For addressing the above problem, when design side gas curtain, a guide can be set at present, be used for guiding the side inflatable curtain deployment, bear the impulsive force of gas curtain simultaneously, avoid the trim panel fragmentation.
Existing guide is a metal sheet, and metal sheet is by welding or being bolted on the body side wall, and the side gas curtain is arranged in the metal sheet top, in side inflatable curtain deployment process, metal sheet bears the gas curtain impulsive force, and gas curtain then launches along metal sheet, goes out from the car roof liner.
The advantage of metal plate type guide is that cost is lower, but the metal sheet volume is bigger, and the offside confining space is had relatively high expectations, and the overlap joint of part is on every side had relatively high expectations.
Summary of the invention
The purpose of this utility model provides a kind of car side inflatable curtain deployment guide that takes up room little, can guide the side inflatable curtain deployment reliably, and assurance side gas curtain is gone out from top cover liner and trim panel smoothly.
Car side inflatable curtain deployment guide described in the utility model is that one group of opposed edges by rectangle sheet material overlaps the cylindrical body that forms mutually, axially be provided with guide plate in the cylindrical body bottom along cylindrical body, this guide plate has a down dip near a side direction at two overlap joint edges, and cylindrical body is provided with the installation journal stirrup.
In the two edges of overlap joint, lower edge is positioned at the inboard of top edges mutually.Can prevent like this that in the sedan-chair driving process side gas curtain drops out between cylindrical body two overlap joint edges.
The both sides and the cylindrical body of guide plate combine as a whole.
The annular of the rectangular shape of cross-sectional plane of cylindrical body, two overlap joint edges are positioned at a side of cylindrical body, and described installation journal stirrup is fixed on the opposite side of cylindrical body.
During installation, by journal stirrup is installed this car side inflatable curtain deployment guide is fixed on the body side wall, and the side gas curtain is interted in the cylindrical body of guide.
The upper and lower edge of overlap joint forms a line of rupture in a side of cylindrical body mutually, will go out expansion from this line of rupture when the side gas curtain detonates.The side gas curtain is gone out the process from cylindrical body, and the lower edge of overlap joint will overturn downwards, is the expansion guiding of side gas curtain with guide plate.
The impulsive force that car side inflatable curtain deployment guide described in the utility model produced when can be good at bearing the side gas curtain and detonating, do not make the fragmentation of car trim panel, simultaneously can guide the side inflatable curtain deployment reliably, avoid the side gas curtain to be tangled by trim panel, assurance side gas curtain is gone out from top cover liner and trim panel smoothly.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the axonometric drawing of car side inflatable curtain deployment guide described in the utility model.
Fig. 2 is the working state schematic representation of this car side inflatable curtain deployment guide.
The specific embodiment
As shown in Figure 1, this car side inflatable curtain deployment guide is one group of opposed edges, 2, the 5 mutual cylindrical body 1 that form that overlap by TPO rectangle sheet material, the annular of the rectangular shape of cross-sectional plane of cylindrical body 1, two overlap joint edges 2,5 are positioned at a side of cylindrical body 1, make cylindrical body 1 one sides form one along the axial line of rupture of cylindrical body 1, in the two edges 2,5 of overlap joint, lower edge 5 is positioned at the inboard of top edges 2 mutually.Axially be provided with guide plate 6 in cylindrical body 1 bottom along cylindrical body 1, the both sides of guide plate 6 and cylindrical body 1 combine as a whole, and guide plate 6 has a down dip near a side direction at two overlap joint edges 2,5, and the opposite side of cylindrical body 1 is fixed with the installation journal stirrup 4 of two band mounting holes 3.
As shown in Figure 2, during installation, by journal stirrup 4 is installed this car side inflatable curtain deployment guide is fixed on the body side wall, and side gas curtain 7 is interted in the cylindrical body 1 of guide.
