Abstract
A car back row safety protection device is characterized in that a back row safety air bag is mounted on the back surface of a front row seat backrest, when the back row safety air bag is detonated, the air bag unfolds directly backwards, faces a back row seat and forms an air cushion. As the back row safety air bag is additionally arranged on the back surface of the front row seat backrest, when car head-on collision occurs, the back row safety air bag is detonated, the air bag unfolds directly backwards to face a passenger and form an air cushion, so as to buffer the kinetic energy of the movement of the passenger's head and chest; in coordination with the safety belt, the head and neck of the passenger sitting in the back row are protected, and damage to the passenger's head and neck is decreased, so that better protection to the passenger sitting in the back row is realized.
Description
Technical field
The present invention relates to a kind of automobile rear safety guard.
Background technology
Head-on crash for automobile; front-seat driver and crew generally have the protection of car belt, safe automobile air bag; with protection driver and crew head, neck and chest; reduce driver and crew's injury; and for the occupant 4 who takes advantage of seat back row; then in the front bumps process, have only the safety strap protection and do not have the protection of safety air bag, as shown in Figure 1.When automobile generation head-on crash, occupant 4 on the back seat 2 will move forward because of inertia, under the constraint of car belt, head still has to bump with the backrest of front-row seats 1 or headrest and causes the risk that injures, head is because of the inertia whipping, cause cervical spine injury, therefore, head, neck position injury values is bigger.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of can reduce back row occupant's head, the injury of neck position when auto against, for back row occupant provides the automobile rear safety guard of better protection, thereby improve vehicle safety performance.
The automobile rear safety guard that the present invention relates to, its special character is: back row's safety air bag 3 is installed in the backrest back of front-row seats 1, and back 3 after-damp bag 301 expansion directions of row's safety air bag are that the dead aft is towards back seat 2 and form air cushion.
Described airbag 301 expansion shapes are spheroidicity or are cylindricality.
Described back row's safety air bag 3 is installed in the top of front-row seats 1 inner skeleton 101.
The invention has the beneficial effects as follows: the back row's safety air bag that has increased fixing front-seat backrest back; when automobile generation head-on crash, back row's safety air bag point is quick-fried, and airbag launches; expansion direction is the dead aft; in the face of the occupant, form air cushion, with buffering occupant's head, the motion energy of chest; cooperate safety strap; protection rides in back row's occupant's head, neck position, reduces the injury of occupant's head, neck, thereby back row's occupant is played the better protection effect.
Description of drawings
Fig. 1 is existing automotive interior structural representation;
Fig. 2 is structural representation of the present invention;
Fig. 3 is that back row's safety air bag (oblate spheroid shape) launches the initial condition scheme drawing;
Fig. 4 is the complete deployed condition scheme drawing of back row's safety air bag;
Fig. 5 is that airbag (cylindricality) launches the initial condition scheme drawing;
Among the figure: 1. front-row seats, 101. skeletons, 2. back seat, 3. back row safety air bag, 301. airbags, 4. occupant, 5. shoulder belt, 6. waistband.
The specific embodiment
As shown in Figure 2, install on the top of front-row seats 1 inner skeleton 101 and fixedly have
Back rowSafety air bag 3,3 after-damp bag 301 expansion directions of back row's safety air bag are that the dead aft is towards back seat 2, towards occupant 4 and form air cushion.Described airbag 301 expansion shapes are spheroidicity.
Because back seat 2 may be taken children or put baby seat, in collision process, back row's safety air bag 3 launches may cause children to damage or other unpredictalbe injury, can be equipped with on gauge panel and suppress the switch that back row's safety air bag 2 detonates.
As shown in Figure 3, when automobile generation head-on crash, the airbag 301 of rear-seat airbag device 3 launches, because effect of inertia, the occupant 4 who sits on the back seat 2 travels forward, and produces constrained force F1 and F2 respectively with shoulder belt 5 and the waistband 6 of safety strap, and direction as shown in the figure, constraint takes advantage of seat in the occupant's 4 of back seat 2 the trend that travels forward, and occupant 4 sense of motion as shown in the figure.
As shown in Figure 4, occupant 4 forwards moves, contact with the airbag 301 of rear-seat airbag device 3, shoulder belt 5, waistband 6 combineds action with safety strap, absorb occupant 4 motion energy, reduce the kinematic velocity of head, chest, the risk that the hard thing on reduction and the front-row seats 1 bumps, thereby the injury of reduction occupant's 4 head, neck and chest.
Children's ride-on is arranged on back seat or do not have the occupant, chaufeur can cut off the air bag firing circuit by switch, in collision process, reduces risk and waste.
As shown in Figure 5, described airbag 301 expansion shapes are cylindricality.
Below only be a specific embodiment of the present invention, but design concept of the present invention is not limited thereto, all the present invention of utilization conceive the insubstantial modifications that the present invention is made, and all fall within protection scope of the present invention.
