Abstract
A knee air bag for a vehicle has an inflator, a diffuser and a cushion to protect a passenger'"'"'s knee when the cushion is deployed. The knee air bag also includes an inflator connector which is provided on a back of the cushion, and an external tether which is provided on an upper portion of the inflator connector and secured at lower and upper ends thereof to the back of the cushion, thus guiding the cushion so that the cushion is deployed upwards. The knee air bag makes the cushion come into close contact with a seatback of the vehicle when the knee air bag is deployed, thus reducing interference with a roof air bag located at an upper position, therefore preventing a passenger'"'"'s head or neck from suffering secondary injuries.
