KNEE AIRBAG DEVICE FOR VEHICLE

摘要

In order to reduce or prevent the application of an axial force to the shins of an occupant with a small build and to the shins of an occupant with a medium build, and in order to ensure the performance of protecting the knees of an occupant with a large build, a knee airbag device (16) for a vehicle is provided with a knee airbag body (48) which is formed in a thin bag-like shape and which, when supplied with gas, is inflated and expanded from below upward along the design surface of an instrument panel lower member (14). The protection section (48B) of the knee airbag body (48) has a size capable of covering the knees of occupants ranging from those with a small build (alternate long and two short dash lines) to those with a large build (alternate long and short dash lines). A U-shaped upper tether (56) is disposed in the upper part within the protection section (48B), and vertical partition sections (54A) are extended upward from portions corresponding to the knees of an occupant with a medium build (continuous lines).
