Sensors in the
crumple zone, just behind the front bumper, send signals to an airbag "central control" indicating the scale of the impact.
Otherwise known as a
crumple zone, this is an area designed to absorb energy in a collision.
``As a result, the full force of the impact was transferred from the relative safety of the
crumple zone to the areas where the passengers sit."
The XC90 reduces that risk by having a lower cross-member fitted to the subframe which activates any oncoming car's
crumple zone as intended, giving occupants maximum protection.
The main safety features include an energy-absorbing
crumple zone above the front wheel, two seat belts, optional anti-lock brakes, aluminium safety cell, special seat and headrest and BMW Telelever front suspension as an additional energy absorbing component.
Sensors in the
crumple zone provide advance signals indicating the severity of a head-on collision.
The XC90 reduces that risk by having a lower cross-member fitted to the sub-frame which activates any oncoming car's
crumple zone as intended, giving occupants maximum protection.
One important aspect is making use of the virtual
crumple zone: this term refers to the time that elapses between the vehicle's response to sensor signals in the pre-accident phase and the impact itself.
Some of Essentra's packaging solutions contain a "
crumple zone" that create space around fragile products such as glass vials for added protection.
In addition,
crumple zone steel located outside the passenger compartment allows for an impact to be absorbed, thus also protecting the lives of occupants inside the safety cell.
Designed with bodily features that may be present if human beings evolved to withstand the forces involved in crashes, Graham has a thick, helmet-like skull with an in-built
crumple zone to absorb impact forces and prevent damage to the brain.
