- a vehicle frame and a vehicle bumper;
- and
- a crush can supporting the vehicle bumper on the vehicle frame;
- the crush can having an inflation chamber and being inflatable from an uninflated state to an inflated state;
- and
- an inflator in fluid communication with the inflation chamber of the crush can, the inflator being designed to generate a pressure within the inflation chamber of the crush can of between 138 kilopascals and 241 kilopascals.

A vehicle-bumper assembly, comprising:
- a vehicle bumper;
- a first crush can positioned in a cavity of the vehicle bumper, the first crush can having an exposed base for attachment to a forward face of a first frame rail of the vehicle, the first crush can having a first inflation chamber to transition from an uninflated state to an inflated state;
- a first inflator in fluid communication with the first inflation chamber, the first inflator being designed to generate a pressure of between 138 kilopascals and 241 kilopascals for a duration of between 20 milliseconds and 40 milliseconds;
- and
- a second crush can positioned in the cavity of the vehicle bumper, the second crush can having an exposed base for attachment to a forward face of a second frame rail of the vehicle, the second crush can having a second inflation chamber to transition from an uninflated state to an inflated state, wherein
