Abstract
The invention discloses an automobile safety belt assembly which comprises an automobile safety belt assembly body and also comprises an air bag, an air guide tube and an air generation device, wherein the air bag is arranged in a safety belt, one end of the air guide tube is connected with the air bag, and the other end of the air guide tube is connected with the air generation device. The automobile safety belt assembly can reduce the hurt caused by the safety belt to a passenger in the binding process when an automobile collides.
Description
Technical field
The present invention relates to the parts of automobile, relate to a kind of car belt assembly in particular.
Background technology
In order to guarantee driving safety, existing automobile is provided with safety strap and safety air bag.Along with the raising of automobile driving speed now, the protection that vehicle provides the occupant requires also to improve constantly.Safety strap for existing structure; In a single day automobile bumps under high-speed travel state; Safety strap damages the occupant in the constraint process easily, and particularly easy thigh and chest to the occupant damages, and the safety strap of therefore existing automobile can not satisfy the requirement to passenger protection.
Summary of the invention
The purpose of this invention is to provide a kind of car belt assembly, the injury that safety strap causes the occupant when bumping to reduce automobile in the constraint process.
Car belt assembly according to the invention comprises safety strap, also comprises air bag, gas channeling pipe and gas generating unit, and air bag is arranged in the safety strap, and an end of gas channeling pipe is connected with air bag, and the other end is connected with gas generating unit.
Said air bag is a collapsible air bag in a tubular form, offers aperture on the air bag.
The gas generating unit of car belt assembly according to the invention is installed on the sill strip through the U-shaped mounting bracket.When automobile bumps; Sensor can be measured the seriousness of collision in moment; The gas generating unit that is positioned on the sill strip charges into the air bag of safety strap with gas through the gas channeling pipe, and the tubulose air bag in the safety strap expands through gas and launches, behind the airbag deployment in the safety strap; Before gas in the air bag distributed through the aperture on the air bag, safety strap can keep swelling state in the several seconds.
Car belt assembly according to the invention; Owing in safety strap, be provided with air bag; When automobile bumped, air bag can cushion bump pressure effectively, increases the area of contact of safety strap and human body simultaneously; Thereby reduced the pressure that safety strap applies human body in to the occupant restraint process, reduced the injury that safety strap caused the occupant when automobile bumped in the constraint process.
The cae analysis checking result of the present invention and existing car belt contrasts as shown in table 1.
Table 1:
Can know by table 1, the motion of car belt assembly ability active constraint dummy hip according to the invention, particularly evident to reducing thigh compressive force effect, the while also can be reduced the injury values of chest.It is thus clear that car belt assembly according to the invention can effectively improve the safety of occupant under the high-speed crash situation.
Description of drawings
Fig. 1 is installed in the axonometric drawing on the vehicle body for the present invention;
Fig. 2 is installed in vehicle body upper edge automobile longitudinal view for the present invention.
The specific embodiment
In order further to explain technical scheme of the present invention, come in conjunction with the drawings below the present invention is set forth in detail.
As depicted in figs. 1 and 2, this car belt assembly safety strap 1 also comprises air bag, gas channeling pipe 3 and gas generating unit 5, and air bag is arranged in the safety strap 1, and the collapsible air bag in a tubular form offers aperture on the air bag.One end of gas channeling pipe 3 is connected with air bag, and the other end is connected with gas generating unit 5.Gas generating unit 5 is installed on the sill strip 7 through two cranses 4.
