  • Patent number: 11299116
    Abstract: A variable back beam and a method of allowing an inflator to vary the variable back beam in case of collision. The variable back beam includes a main beam connected to a front end module carrier, an inner beam inserted into each of both sides of the main beam, and an operation member operable to move the inner beam in a vehicle-width direction at the time of left front or right front collision of the vehicle. Since the back beam is extended in length at the time of collision, the impact area or shock absorption area of the back beam can be increased, the impact on the back beam, a crush box, and a collision object can be reduced, and particularly, it is possible to reduce the crush length of the left or right end of the back beam.
