Abstract
The invention relates to a side airbag for vehicles. The side airbag comprises a gas generator and an air bag, wherein the air bag is provided with an abdomen air chamber and a chest air chamber and the gas outlet of the gas generator is arranged in the abdomen air chamber; a chamber separating structure capable of being torn by gas pressure in the abdomen air chamber is arranged between the abdomen air chamber and the chest air chamber, the chamber separating structure comprises sewing threads for sewing bag pieces on two sides of the air bag or damping cloth pieces arranged in the air bag; and the gas generator inflates the abdomen air chamber, when pressure difference between the abdomen air chamber and the chest air chamber is increased to a certain degree, and the gas tears the chamber separating structure and is full of the chest air chamber. The side airbag is simple in structure and easy to produce, the chamber separating structure capable of being torn is arranged on the air bag, so that smooth inflation can be achieved, and the cost can be greatly reduced for mass production.
Description
Technical field
The present invention relates to a kind of safety air bag of self-propelled vehicle, especially relate to a kind of automobile-used side airbag.
Background technology
In the automobile side angle collision; Almost be full of chest and belly airbag during general-utility car chest abdomen formula side airbag deployment simultaneously; Chest and belly are acted on simultaneously; But when some car body structure reason caused side collision, the side air bag of common form well balance operator chest and belly was stressed.
Therefore, there is the contriver to propose the mode of each chamber sequential inflation, is designed to during the side collision incident, provide improved occupant's buffering advantageously to allow inflation pressure and chamber inflation sequence.The public technology of " multi-chambered air bag that is used for self-propelled vehicle " (publication number CN 1792680A) for example by name promptly is an improving technology in this respect, and it is at each chamber and occupant's head, shoulder, and chest, or pelvis area is associated; Isolator is arranged between the adjacent chamber; Chamber can be inflated to different pressure and with various sequential inflation.Though but this public technology sequential inflation, the buffer depth that increases, complex structure is difficult for processing, and cost is higher.
Summary of the invention
But main purpose of the present invention provide a kind of simple in structure, be easy to make, the automobile-used side airbag of lower-cost sequential inflation.
Above-mentioned technical matters of the present invention mainly is able to solve through following technical proposals: a kind of automobile-used side airbag; Comprise gas generator and airbag; This airbag has belly air chamber and chest air chamber, and the air extractor duct of this gas generator is positioned at the belly air chamber; It is characterized in that: be provided with the cavity separation structure that can be torn by the gaseous tension in the belly air chamber between belly air chamber and the chest air chamber, this cavity separation structure comprises the sewing thread that the bag sheet of airbag both sides is sewed up or is located at the damping cloth sheet in the airbag; Gas generator is to the inflation of belly air chamber, and when the draught head between belly air chamber and chest air chamber increased to a certain degree, gas was torn the cavity separation structure and is full of the chest air chamber.The mechanism of this programme is at chest belly intersection, promptly between air bag belly air chamber and chest air chamber, but a tear seam thread line or a lacerable damping cloth sheet is set; The gas generator pneumatic head fills the belly air chamber earlier in the belly air chamber, when coming pressure to increase; Tearable schizocele body separation structure; Promptly tear sewing thread or damping cloth sheet, gas begins to be full of the chest air chamber, thereby realizes sequential inflation; Deflation hole is located on the chest air chamber, impels the inflation earlier of the whole gas replenishment process midriff of airbag, and pressure is greater than the chest air chamber, thereby strengthens the application force to operator's belly.Lacerable cavity separation structure is set on air sac bag body, simple in structure, be easy to make, for producing manufacturing in enormous quantities, cost can reduce significantly.
As preferably, said cavity separation structure is the isolation structure that two bags of sheets that airbag reclines the bag middle part through sewing thread when being flat form are sutured in one.Under the bag flat form, sew up, make a bag sheet be easy to sew up, reduce difficulty of processing, also make bag integral body be easy to keep smaller volume, be beneficial to the saving parking space, be more suitable for using in the car.
As preferably, the bag chamber that is between the adjacent stitches of sewing thread forms the gap that can ventilate.Can be when the belly air chamber be gas filed; Portion gas can get into the chest air chamber through this gap; Before the sewing thread tear fracture,, avoid between belly air chamber and the chest air chamber pressure reduction excessive for the chest air chamber provides a certain amount of gas; Make that air-flow comparatively stably gets into the chest air chamber behind the tear fracture, be beneficial to speed that the chest air chamber launches, the external strength under shock of protection; Control the size in this gap, can play the shock damping action of air-flow.
As the equivalent of above-mentioned cavity separation structure scheme, said cavity separation structure is the damping cloth sheet that is sutured in the airbag intracavity sidewall; On the length direction of damping cloth sheet, be provided with several arranged in column sections of tearing, this section of tearing is groove or pore structure, and the groove depth of this groove is not less than 1/3 of damping cloth sheet thickness.Groove or pore structure make the intensity at this place lower, under certain pressure reduction, are easy to break off.The groove depth of groove is not less than 1/3 of damping cloth sheet thickness, can ensure that groove can break off.
As preferably, the said section of tearing is provided with row at least.Tear Duan Chenglie and be provided with, make each section of tearing be easy to continuous disconnection, one of them disconnection intensity is big slightly, also can driven and tear by the adjacent section of tearing.When one row are above, when a row inefficacy therein, can break off, improve whole reliability by other sections of tearing.
As another equivalent of above-mentioned cavity separation structure scheme, said cavity separation structure is the damping cloth sheet that is sutured in the airbag intracavity sidewall; This damping cloth leaf length direction is provided with several holes that connects belt body, is provided with the section of tearing between the adjacent holes, and this section of tearing is groove or pore structure, and the groove depth of this groove is not less than 1/3 of damping cloth sheet thickness.This structure has higher lacerable reliability, through tearing of the section of tearing with the complete conducting of 2 air chambers.During the ventilation of belly air chamber, portion gas can get into the chest air chamber through the hole, and when the draught head of 2 air chambers acquired a certain degree, the section of tearing.
As another equivalent of above-mentioned cavity separation structure scheme, said cavity separation structure is bonded in the bag adhesive section of one for the two side pocket sheets that when airbag is flat form, the bag middle part reclined; Binding part in the bag adhesive section is made up of some bonding points, and the bag inner chamber between the adjacent bonding point constitutes gas passage.This bonded assembly structure, simple in structure, cost is lower, is easy under draught head, break off.
As preferably, the bag of airbag is that two folded mutually bag sheets are sewed up the structure that forms on the edge of.Being convenient to make, is that air bag integral structure volume is less, practices thrift usage space in the car.
Therefore, that the present invention has is rational in infrastructure, be easy to characteristics such as making, especially has characteristics simple in structure, as to be easy to make, can reduce greatly the manufacturing cost of production in enormous quantities.
