Front section for a motor vehicle body

A front section of a body of a motor vehicle, comprising:

• a bumper having an upper cross bracket and a lower cross bracket, said lower cross bracket having a front-most point disposed forwardly of said upper cross bracket, said bumper being adapted to retreat rearwardly during a frontal collision while absorbing energy and momentum;
• and
• a fresh air passage structure having a top horizontal frame member, a bottom horizontal frame member, and a shutter assembly connected therebetween, said shutter assembly being situated behind said bumper, said shutter assembly being adapted to modulate a throughput of air through the fresh air passage structure and thereafter to a motor, the shutter assembly being situated upstream of said motor;
• wherein said upper cross bracket is above said shutter assembly, and said lower cross bracket is below said shutter assembly;
• wherein said bumper and said shutter define a longitudinal gap that allows said bumper to retreat rearwardly during a first part of a frontal collision without causing said shutter assembly to simultaneously retreat with said bumper;
• and
• wherein said bumper is configured to contact said fresh air structure during a second part of a collision to close said longitudinal gap and thereby cause said shutter assembly to retreat along with said bumper when said gap is closed.
