Abstract

The utility model relates to a curtain-type automatic inflating bag device for an automobile, composed of a bag, a housing, a compressed gas cylinder, an electromagnetic valve, a circuit board and an infrared detector which is connected with circuits in front of the automobile. The housing is arranged above the front of pates of people who are in the automobile. The bag is crimped on a main shaft in the housing or is folded in the housing. The compressed gas cylinder, the electromagnetic valve and the circuit board are sequentially arranged at one side of the housing. A conduit of the compressed gas cylinder is communicated with the bag. When the infrared detector detects that the automobile or other objects approach to the automobile body, the electromagnetic valve is opened. The gas in the compressed gas cylinder is shot into the bag and causes the bag to expand, so that the people in the automobile are avoided injuring.

Description

The automobile automatic inflatable pneumatic bag device of curtain formula

The utility model relates to a kind of automobile with the automatic inflatable pneumatic bag device of curtain formula, belongs to automobile safety precaution articles for use.

The purpose of this utility model is that a kind of automobile automatic inflatable pneumatic bag device of curtain formula will be provided, and it can prevent to protect when automobile is subjected to clashing in advancing occupant face, head to preserve from, and helps safe driving.

The purpose of this utility model is achieved in that the automobile automatic inflatable pneumatic bag device of curtain formula, by inflatable pneumatic bag, housing, compressed gas cylinder, electromagnetic valve, circuit card and constituted with the infrared detector that circuit is connected in vehicle front, this housing is installed on front upper place, the occupant crown, inflatable pneumatic bag is curled on the interior main shaft of housing or is folded in the housing, compressed gas cylinder, electromagnetic valve, circuit card is installed on a side of housing in proper order, compressed gas cylinder is connected with inflatable pneumatic bag with conduit, when outer red line detector is measured vehicle or other object near car body, electromagnetic valve is opened, gas enters rapidly and makes its expansion in the inflatable pneumatic bag in the compressed gas cylinder, and the occupant is escaped injury.

The utility model advantage: 1, the utility model borrows infrared detector to discover object near vehicle, start electromagnetic valve by circuit card, make pressure gas import in the inflatable pneumatic bag rapidly, with the air bag that becomes the curtain shape expansion of extending downwards, retaining is in face of the occupant, passengers inside the car avoided parts or the vehicle glass fragment injures when vehicle was impacted, so help safe driving.

2, the utility model is simple in structure, and after compressed gas cylinder discharges air at every turn, need only change compressed gas cylinder, and this device can use as usual, so can reduce expenses.

3, the utility model can supply multiple transportation meanss such as general-utility car, outing vehicle, train to install and use, and is applied widely.

The utility model concrete structure is provided by following examples and accompanying drawing thereof.
