Embodiment Construction

[0014] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail, but the protection scope of the present invention is not limited to the examples.

[0015] Such as Figure 1-2 As shown, the present invention integrates an airbag in a traditional common seat headrest, thereby reducing the distance between the occupant's head and the headrest by triggering the airbag when a rear collision occurs, and providing soft support for the head To reduce or avoid head and neck injury.

[0016] in, figure 1 is the state before the headrest airbag is triggered; figure 2 It is the state after the head restraint airbag is triggered. When the headrest airbag is ignited, all the intense chemical reactions are completed in the metal gas generator. By adjusting the folding method of the air bag of the air bag, the air bag can be inflated and expanded along the side o...

Abstract

The invention relates to the field of automobile safety, in particular to a headrest airbag, which is arranged in the headrest of an automobile seat and used to protect the head and neck of occupants in the vehicle. Compared with the existing head and neck protection system WHIPS and the active head restraint, each parameter of the head restraint airbag of the present invention is easier to control, and there are fewer restrictions on geometrical dimensions during design.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a headrest safety airbag. Background technique [0002] Head and neck injuries are the most common injuries in traffic accidents. In Sweden alone, 25,000 people suffer from such injuries every year. The proportion of permanent head and neck injuries accounts for about one-tenth of the total number of injured people. When the vehicle collides, the occupant's body and head will be protected due to the support of the seat and headrest. But at this time, the neck is not supported, so it will bear a lot of pressure and cause damage to the neck. The head and neck protection system will properly collapse the headrest and recline the seat in the event of a collision, so as to reduce the impact on the neck caused by the collision, thereby preventing the spine of the occupant from being pulled backwards, and also It can prevent the occupant's head from swinging forward and hitting the ...
