JP2004224325A - Protection device for occupant by air pillow against air bag - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To solve problems that a driver applies brakes abruptly and inevitably to avoid danger when an automobile collides on its front part, the heads of the driver and an occupant on a front passenger seat protrude forward, and their bodies take forward inclined attitude even if their bodies are supported by seat belts and such accidents can be seen all over the world that their heads are thrown back abruptly due to reaction of the explosion force of an air bag operating instantaneously with collision, causing breakage and injury of a bone in the neck and injury and cutting of the carotid artery which result in death. <P>SOLUTION: This protection device for the occupant by an air pillow 3 against the air bag 1 to prevent the accident resulting in injury or death is constituted in such a way that the occupant's seat belt 6 and the air pillow 3 including aggregate 7 are integral with a seat with a headrest to form the air pillow 3 automatically due to occupant's inertia moving and occupant's natural body position moving by braking force to prevent front face collision of the vehicle and an air vent 4 and an air intake port 5 are provided to fill air into the air pillow 3 automatically. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

In the event of a car collision, the occupant's gravity causes inertial movement, the body position is pushed forward, the distance between the occupant's head and the seat's headrest increases, and if the airbag explodes in front of the occupant's head, The medical results indicate that only the part is bent backwards and the bone of the human neck is weaker in the direction in which it is turned back than it is in the forward direction. In order to prevent death or injury due to arterial amputation, it was developed with the purpose of using an air pillow that uses the force of the occupant's inertial movement.
[Brief description of the drawings]
Fig. 1 When the driver steps on the vehicle's brakes against an obstacle in front while driving a car, inertia force inevitably works, the body position is tilted forward, and the driver is integrated with the driver. Since the seat belt of ▼, the air pillow of ③ and the aggregate of ７7 are tilted forward together with the driver, inevitably from the air hole of 取 り 入 れ 4 and the air intake of ５5, Air is automatically filled into the air pillow.
[Fig. 2] Immediately after a forward collision of the vehicle, the airbag of (1) rapidly expands to protect the occupant's head of (2) from protrusions such as a front steering wheel. In the case of rapid inflation, without the air pillow in (3), the head of the occupant in (2) was bent backwards from the neck in the shape of a "ku", breaking the neck bone and cutting off the Ciliary artery. An air pillow of (3) was installed to prevent accidents.

Claims (1)

A device that protects the occupants with an air pillow created by moving the occupant by operating the air back on the front of the vehicle seat.
