Abstract
The invention discloses a supplemental restraint system. The supplementary restraint system comprises collision sensors, an air bag computer, an air bag indicator lamp and an air bag assembly. The collision sensors comprise the triggering collision sensor and the protection collision sensor. The triggering collision sensor is also known as the collision strength sensor and is used for detecting the deceleration or the inertia existing during collision and transmitting a collision signal to the air bag computer, and the collision signal is used as a triggering signal of the air bag computer. The protection collision sensor is also known as the safety collision sensor. The protection collision sensor is connected with the triggering collision sensor in series and is used for preventing an air bag from mistakenly going off. The air bag computer is the key component of the supplemental restraint system. The air bag computer is located on a lower holding face of a central control board in a cab. The air bag indicator lamp is located above an instrument board. By the adoption of the supplemental restraint system, impact force can be evenly distributed to the head and the chest, it is avoided that the fragile passenger flesh directly collides with a vehicle body, and the possibility of an injury is greatly reduced.
Description
Technical field
The present invention relates to a kind of gas-bag system, particularly a kind of air bag system.Belong to car assembling technical field.
Background technology
Safety air bag, is arranged on the place ahead in car (positive co-driver), side (front row and rear row in car) and three directions of roof.The function of safety air bag is to alleviate occupant's extent of injury when collision happens accident, avoids occupant that secondary collision occurs, or vehicle occurs to be pulled out away from seat under the dangerous situations such as rolling; If bumped, air inflator system can be inflated rapidly within the time less than 1/10th seconds, and air bag will be gone out bearing circle or gauge panel when expanding; Thereby make occupant avoid the impact of the forward collision application force that produces, after a second, air bag will shrink (on air bag, having many apertures) greatly, therefore can not hinder occupant's action.Safety air bag is comprised of three parts: air bag, sensor and air inflator system.
The use of safety air bag has obviously improved the passive satety of automobile.According to statistics, due to safety air bag being widely used in North America, make death rate of accident reduce 12%, and the injured degree of human body also alleviates to some extent under air bag for protection, on the other hand, although the air bag quality of being made by nylon or polyester fiber cloth etc. is little, the speed that moment launches is up to more than 200km/h, and this velocity of impact is not a peanut for human body; In the middle of several years of future, safety air bag still can be played the part of important role in automotive safety equipment; Engineers can be carried out the possibility of self-align active safety system what find to contingent accident and vehicle drive person, the exploitation of Novel intelligent safety air bag is had higher requirement to up-to-date technology; When the distance of chaufeur relative direction dish air bag lining lid is less than 10cm, the air bag launching 20～30 milliseconds of implodes will be given the impact injury that chaufeur is fatal; And if member on front passenger's seat does not keep suitable sitting posture, in collision, cause injured possibility also can greatly increase, current, there are two kinds of development tendencys in safety air bag, and the U.S. and Japanese car company are making great efforts augmented airbag size and protecting occupant; And some auto makeies of Europe, as benz, BMW and Volvo etc. are thought, safety air bag itself ensures occupant's miraculous cure anything but, it must could effectively play a role in a unified automobile passive safety system, in this system, must possess seat, children special-purpose seat and a series of other parts of deflation formula safety strap, reliable in structure.And, be preferably in the installation of just considering all necessary constituent elementss of this safety system when body structure design starts.The intelligent development of following safety air bag, has also comprised advanced sensor technology and information handling system integrated, and the information aspect failure-free impact environment can be provided in the blink that they occur in accident.These information comprise the severe degree of auto against, the form of collision, occupant's stature, body weight, seating position and take attitude and occupant whether with belt etc.; Intelligent Safety Airbag System is according to the information that detects, by the computational analysis of its electronic control system, when determines safety air bag and with which kind of degree launches, thereby providing optimized protection to occupant.
Summary of the invention
Goal of the invention: to have in order overcoming in prior art the problem that can not fast speed ejects safety air bag, to the invention provides a kind of low pressure tank of pull-out type fast and easily.
Technical scheme: for achieving the above object, the invention provides a kind of air bag system and comprise crash sensor, air bag computer, air bag indicator lamp, air bag component, described crash sensor is divided into described triggering crash sensor and described protection crash sensor.Described triggering crash sensor is also referred to as impact strength sensor, deceleration/decel or inertia during for detection of collision, and collision alarm is passed to air bag computer, as the energizing signal of air bag computer; Described protection crash sensor is also referred to as safety collision sensor, it is connected with triggering crash sensor, be used for preventing that air bag mistake is quick-fried, it is the core component of gas-bag system for described air bag computer, described air bag computer is positioned at driving compartment center console and transfers face, described air bag indicator lamp is positioned at instrument carrier panel top, and described air bag component comprises air bag, gas generator and firing unit.
Safety air bag of the present invention can be evenly distributed in impact head and chest, prevent that fragile passenger's human body and vehicle body from producing direct impact, greatly reduce injured possibility, safety air bag is for when suffering frontal impact, really can effectively protect passenger, even if be not, volume during air bag outburst approximately only has 130 decibels, in the endurable scope of human body; In air bag, 78% gas is nitrogen, very stable and containing toxicity, harmless; The powder of taking out of while producing is to maintain air bag not coherent lubricated powder under folded state, also harmless to human body.
Described gas-bag system is when automobile bumps while causing storage battery and electrical generator and gas-bag system to disconnect, and backup power is opened in 4～6s within a certain period of time, can maintain like this gas-bag system power supply.
Described air bag is circular, and actv. removes to protect head like this.
Safety air bag indicator lamp operation irregularity, after disconnecting B+, should wait for 10min, then operate, during dismounting steering handwheel, should use special tool lock for steering column to be fixed on to the position of " directly forward ", to guarantee that control setup and spiral wire harness can be not damaged in installation.
Gas generator function is when firing unit is ignited fire lighter, produces gas to airbag aeration, and air bag is popped, air bag producer uses special bolt to be fixed on air-bag support, only have the special tool of use just can assemble, gas generator, from installation, is answered and is changed 1 time for 10 years.
Beneficial effect: prior art of the present invention is compared tool and had the following advantages:
1, safety air bag of the present invention can be evenly distributed in impact in head and chest, prevents that fragile passenger's human body and vehicle body from producing direct impact, greatly reduces injured possibility;
Volume when 2, air bag of the present invention breaks out approximately only has 130 decibels, in the endurable scope of human body; In air bag, 78% gas is nitrogen, very stable and containing toxicity, harmless;
