Abstract

The utility model aims to provide an automobile seat headrest capable of effectively protecting the head and the neck of a passenger after a vehicle has rear collision. The automobile seat headrest comprises a headrest body and a headrest support; the key points are as follows: a safety airbag capable of expanding to the front direction of the headrest is arranged in the headrest body; the safety airbag is connected with an airbag controller; and the airbag controller is connected with a collision sensor capable of detecting the rear collision of the vehicle. When the vehicle has rear collision, the collision sensor sends a collision signal to the airbag controller, and the airbag controller processes the received collision signal; when the collision signal is weak, the airbag controller does not detonate the safety airbag; and when the collision signal is strong, the airbag controller controls the safety airbag to expand to the front direction of the headrest, so that the distance for the head of the passenger to move backwards can be reduced, and the neck or the head of the passenger is prevented from being injured.

Description

A kind of car seat headrest
Technical field
The utility model belongs to the automotive safety technical field, specially refers to the chair headrest of automobile.
Background technology
Take place in the collision process of back at automobile; occupant's the neck and the damage of head are maximum; though there is chair headrest to provide certain protection to neck and head; but the protection effect is also bad; its reason is as follows: driver and crew's head can't be close to (like that can be very uncomfortable) on the chair headrest at ordinary times; therefore; when the back collision takes place in automobile; passenger's head can be former thereby mobile rapidly backward because of inertia; till head of passenger and chair headrest closed contact, in the process that moves, just may cause personnel's neck or head injury.Therefore say that it is not enough only relying on traditional chair headrest to protect driver and crew's neck.
The utility model content
The purpose of this utility model is the car seat headrest of effective protection driver and crew neck when proposing a kind of can the collision after automobile takes place.
Car seat headrest of the present utility model comprises head rest body and headrest support, key is that described head rest body inside is provided with can be to the safety air bag of headrest the place ahead direction distending, described safety air bag is connected with air spring control, and described air spring control can detect the crash sensor that collides behind the automobile and links to each other with one.
When the back collision took place automobile, crash sensor sent collision alarm to air spring control, and air spring control is handled the collision alarm of receiving, when collision alarm is more weak, and the air spring control safety air bag that can not detonate; When collision alarm was strong, air spring control was controlled safety air bag to headrest the place ahead direction distending, thereby can reduce the distance that head of passenger rearward moves, and avoids passenger's neck or head to sustain damage.The power judgement of collision alarm is determined by early stage Collision test when carrying out the air bag exploitation, the strong and weak standard difference of the collision alarm of different money vehicles.Parameters such as the deflation hole of the type of safety air bag ribbon, the kind of gas generator, air bag, point of ignition, fire point can be optimized when automobile design, to reach best protection effect.
For avoiding there be not the safety air bag that detonates under passenger's the situation, increase maintenance cost, described air spring control also is connected with and is placed in under-seat, can detect the pressure sensor that seat is taken situation.When the measured pressure value of the pressure sensor of seat during less than setting value, just representing does not have the passenger to take on this seat, air spring control will no longer be comprehended the signal of crash sensor this moment, this safety air bag can not detonate when therefore the back collision takes place yet, thereby when guaranteeing safety, saved maintenance cost.
Described safety air bag is fixed on the seat support of headrest the inside by the left and right support of the symmetry at its rear portion; safety air bag can only pop to chair headrest the place ahead after detonating like this; protection passenger neck; the left and right support of symmetry has guaranteed that the expansion direction of safety air bag can not depart from, and further guarantees the safety of passenger's head and neck.
The place ahead of described head rest body connects by suture, is beneficial to safety air bag and pops to chair headrest the place ahead.
Car seat headrest of the present utility model can be protected the safety of passenger's head and neck effectively by in inside safety air bag being set when the back collision takes place automobile, and safety air bag is to be controlled by the air spring control of technology maturation, and is safe and reliable.
Description of drawings
Fig. 1 is the schematic diagram of the car seat headrest of embodiment 1;
Fig. 2 is the structural representation (back view) of the car seat headrest of embodiment 1;
Fig. 3 is the schematic diagram of the car seat headrest of embodiment 2.
The specific embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, 2, the car seat headrest of present embodiment comprises head rest body 1 and headrest support 11, head rest body 1 inside is provided with can be to the safety air bag 2 of headrest the place ahead direction distending, safety air bag 2 is connected with air spring control 3, and air spring control 3 can detect the crash sensor 4 that collides behind the automobile and links to each other with one.
Safety air bag 2 is fixed on the seat support 11 of head rest body 1 the inside by the left and right support 21 of the symmetry at its rear portion; safety air bag 2 can only pop to chair headrest the place ahead after detonating like this; protection passenger neck; the left and right support 21 of symmetry has guaranteed that the expansion direction of safety air bag 2 can not depart from, and further guarantees the safety of passenger's head and neck.
The place ahead of head rest body 1 connects by suture, is beneficial to safety air bag 2 and pops to chair headrest the place ahead.
When the back collision took place automobile, crash sensor 4 sent collision alarms to air spring control 3, and 3 pairs of collision alarms of receiving of air spring control are handled, when collision alarm is more weak, and air spring control 3 safety air bag 2 that can not detonate; When collision alarm was strong, air spring control 3 was controlled safety air bags 2 to headrest the place ahead direction distending, thereby can reduce the distance that head of passenger rearward moves, and avoids passenger's neck or head to sustain damage.
Embodiment 2:
As shown in Figure 3, as different from Example 1, present embodiment is to avoid there be not the air bag that detonates under passenger's the situation, increases maintenance cost, and air spring control 3 also is connected with and is placed in under-seat, can detect the pressure sensor 5 that seat is taken situation.When the measured pressure value of the pressure sensor 5 of seat during less than setting value, just representing does not have the passenger to take on this seat, air spring control 3 will no longer be comprehended the signal of crash sensor 4 this moment, this safety air bag can not detonate when therefore the back collision takes place yet, thereby when guaranteeing safety, saved maintenance cost.
