Embodiment Construction

[0030] figure 1 is a block diagram of the collision process of the first and second vehicles 1, 2 in an oblique collision. Such as figure 1 As shown, the vehicles 1 , 2 will strike each other at an angle 3 determined by the respective longitudinal axes A, B of the vehicles 1 , 2 . exist figure 1 In the example, angle 3 is 15°, which is the angle used by the National Highway Traffic Safety Administration (NHTSA) in the oblique impact test mode. Therefore, when the vehicle 2 hits the vehicle 1 , the passengers seated in the vehicle 2 will be moved into a direction at an angle to the axis B of the vehicle 2 . For example, a passenger may be moving in the general direction shown by arrow C; the direction of passenger movement is determined by a number of known factors, such as speed, angle of impact, center of gravity of vehicles 1, 2, etc. In this case, the occupants seated in vehicle 2 could experience head rotation, and more severe head injuries than could occur in a fronta...

Abstract

A vehicle airbag comprises a primary chamber, a secondary chamber affixed to the primary chamber, and a passage between the primary chamber and the secondary chamber. The primary chamber is configured to contact at least two reaction surfaces, and the secondary chamber is configured to contact one and only one of the at least two reaction surfaces, when the airbag is inflated upon detection of an impact.

Description

Background technique [0001] In a vehicle crash, especially when the crash involves an oblique impact, a likely cause of head injury is the head rotation of the vehicle occupant. For example, vehicles traveling in opposite directions may collide at an angle, hitting each other on the driver's side of the target vehicle. In such a situation, the passenger side occupant of the subject vehicle may experience head rotation, potentially causing a head injury, due to the occupant's head hitting the passenger airbag and rolling toward the driver's side of the vehicle. Current passenger airbags may not have a problem with head rotation in a direct frontal collision. However, current passenger airbags have deficiencies in their ability to reduce head rotation and the associated head injury in oblique collisions. Contents of the invention [0002] According to the present invention, a vehicle airbag is provided, comprising: [0003] main room; [0004] a secondary chamber attached ...
