The utility model solves the technical scheme that its technical matters adopted: a kind of car body with the rear-seat airbag device; Comprise vehicle frame and airbag apparatus; Be installed at least one back seat and one in the said vehicle frame and be arranged in back seat fwd front-row seats; The position that is positioned between back seat and front-row seats on the said vehicle frame and closes on the front-row seats rear portion offers storage tank, is installed on the airbag apparatus that is provided with towards notch in this storage tank, and this storage tank notch is covered with cover plate.
Further be set to: said airbag apparatus comprises control unit, air bag and the gas generator that electrically connects with control unit, is sheathed on the gas generator said air sac sealing, offers deflation hole on this air bag.
Adopt technique scheme; When gas generator is braked and is airbag aeration; Airbag inflation also ejects, and air bag can block the chair back part of front-row seats, the impact airbag when passenger travels forward because of inertia fully; This moment, air bag can keep off the head/chest locations the passenger fully, thereby passenger's personal safety is played a very good protection.
Further be set to: the end that is positioned at air bag on the gas generator is provided with a plurality of air gates, and this gas generator screw thread is fixedly connected on the storage tank bottom land.
Adopt technique scheme, a plurality of air gates can improve the speed that gas generator discharges gas, and the gas generator screw thread is fixedly connected on the storage tank bottom land, has not only made things convenient for Assembly &Disassembly, has also practiced thrift the space, meets aesthetic requirement.
Further be set to: said storage tank is positioned at the position of closing on roof on the vehicle frame and is provided with.
Adopt technique scheme, storage tank is installed in roof, and not only the position is not easy to see, and institute takes up space little.
Further be set to: said bladder shape is the L type, and the bottom of this air bag is towards the direction bending of back seat place.
Adopt technique scheme, air bag is tabular, and this air bag bottom is towards the direction bending of back seat place, and this dogleg section can play passenger's belly and conflict and the buffering effect, improves buffering effect.
Further be set to: said air bag is made up of lateral lobe and top again, and said lateral lobe is the U font, on said top and the lateral lobe wherein a side seals cooperate, each disjunct side all is sealedly and fixedly connected with storage tank on lateral lobe and the top.
Adopt technique scheme, be three-dimensional shape behind the airbag inflation of this structure, the shape thickness that is ejected is even, and buffering effect is better.
The beneficial effect of the utility model is: when having an accident; Control unit is braked the control gaseous producer and is airbag aeration; Airbag inflation also ejects, and the air bag of strip can block the chair back part of front-row seats, the impact airbag when passenger travels forward because of inertia fully; This moment, air bag can keep off the head/chest locations the passenger fully, played a very good protection.Not only simple structure, and productive costs is low, does not also influence passenger's on the front-row seats comfort level simultaneously.
