Problems solved by technology

[0003] The purpose of the present invention is to provide a knee airbag device for a car, which solves the problem that the traditional knee airbag device is difficult to effectively protect the legs of passengers in an all-round way, especially because different passengers have different sitting postures, and their legs may appear In the bent or upright state, a single airbag cannot effectively protect it. In addition, when the traditional airbag is ejected, the installation shell that fixes the airbag may fall off and cause secondary damage to the passenger's legs.

Abstract

The invention discLoses an automobiLe knee airbag device. The device comprises a U-shaped sheLL body formed by sequentiaLLy connecting an instrument paneL sheLL, a steering wheeL fixing sheLL and an airbag fixing pLate, wherein the airbag fixing pLate is fixedLy provided with an airbag sheLL, a partition pLate is fixed in the airbag sheLL, the partition pLate divides the inner portion of the airbag sheLL into a first cavity and a second cavity, the first cavity is internaLLy provided with a curLed first airbag, and the second cavity is internaLLy provided with a second airbag. The automobiLe knee airbag device soLves the probLems that a conventionaL knee airbag device effectiveLy and comprehensiveLy protects the Legs of a passenger difficuLtLy, especiaLLy different passengers have different sitting postures, the Legs may in bent states or verticaLLy straight state, a singLe airbag cannot protect the Legs effectiveLy, in addition, when a conventionaL airbag is ejected, the mounting sheLL body of a fixed airbag may faLL off to cause secondary injury to the Legs of the passenger.

Description

technical field [0001] The invention relates to an automobile safety airbag, in particular to an automobile knee airbag device. Background technique [0002] Electronic airbag is a passive safety protection system, which is used in conjunction with seat belts to provide effective crash protection for occupants. In a car collision, car airbags can reduce the head injury rate by 25% and the face injury rate by about 80%. A knee airbag device is a common in-vehicle airbag that protects a passenger's legs by deploying the airbag between an instrument panel and the passenger's lower legs (eg, shins) in the event of a collision. In the event of a vehicle crash, the airbag prevents occupants from colliding with the dashboard at high accelerations. The instrument panel is made of high hardness material, so when the passenger collides with the instrument panel with high acceleration, a large force will be applied to the legs of the passenger. The airbag apparatus allows the occupa...
