The phrase
"occupant compartment" refers to the interior space or area inside a vehicle where the passengers sit. It represents the designated area for individuals who are riding in the vehicle.
Full definition
The majority of the cars had lots
of occupant compartment intrusion, which contributed to their low overall rating.
Beginning with the 2018 model year, the front - end and
occupant compartment structure was reinforced to improve occupant protection in passenger - side small overlap crash tests.
Extensive intrusion into the lower
occupant compartment limited the driver's survival space and resulted in a poor rating for structure and for leg / foot protection.
Good structure means a
strong occupant compartment or safety cage, crumple zones to absorb the force of a serious crash, side structure that can manage the force of a striking vehicle or struck object and a strong roof that won't collapse in a rollover.
Sleds simulate crash forces, re-creating the accelerations (side or rear impacts) or decelerations (frontal crashes) that occur
inside occupant compartments during full - vehicle crashes.
Honda Civic 4 - door: The 4 - door Honda Civic's
occupant compartment stayed intact during the crash so survival space for the dummy was well - maintained.
Because the side structure and the
rear occupant compartment of the car were not changed, the injury ratings for the passenger and the structure rating are based on tests of both the 2014 and 2015 models.
At the same time, the steering column and driver airbag move inboard in many vehicles because of the way the front end and
occupant compartment deform.
The extended cab (called the access cab) earned an «acceptable» mark for structure due to «
additional occupant compartment intrusion» during the crash, IIHS said.
ARLINGTON, Va. — A beefed - up
occupant compartment takes the Hyundai Santa Fe Sport from a marginal to a good rating in the Insurance Institute for Highway Safety's small overlap front test.
Beginning with 2016 models, the RDX was re-engineered with front - end and
occupant compartment structural modifications to improve occupant protection in both small overlap and moderate overlap frontal crashes.
Convincing drivers to use safety belts and refrain from driving if they're impaired by alcohol are important, too, but these complementary measures are no substitute for making roofs stronger so people in rollovers remain in their vehicles and have
more occupant compartment survival space.»
Often times there is car damage in frontal collisions; however, the increasingly
sturdy occupant compartment, seatbelt, and air bags often allow cars to withstand head - on collisions without serious damage to the occupants.
The structure of the Pontiac G6's
occupant compartment held up well during the frontal test, but there was a problem with the driver seat.
Beginning with 2015 models built after November 2014, the front - end and
occupant compartment structure was modified to improve occupant protection in small overlap frontal crashes.
«The big things the automakers have done to improve crashworthiness are designing better front crush zones to manage crash energy,
stronger occupant compartments to limit intrusion, and stronger roofs to better protect people in rollovers.»
These vehicles are rated separately, except that the structural ratings for both vehicles are based on both tests, as are rear dummy injury and head protection ratings, because no changes were made to the
rear occupant compartment.
Each vehicle's overall evaluation is based on three aspects of performance — measurements
of occupant compartment intrusion, injury measures from a Hybrid III dummy positioned in the driver seat, and analysis of slow - motion film to assess how well the restraint system controlled dummy movement during the test.
At the same time, the steering column and driver airbag move inboard in many vehicles as the front end and
occupant compartment deform.
The occupant compartments in these small cars were severely compromised, often causing injury to the dummy.
During the small front - overlap test,
the occupant compartment remained reasonably intact, and the dummy's condition indicated a low risk of significant injuries.
Its structure must manage crash damage so
the occupant compartment stays intact, and the safety belts and airbags keep people from hitting hard surfaces in - and outside of the vehicle.»
View of the vehicle after the crash with doors removed, showing the side airbags and damage to
the occupant compartment.
The dummy's head remained inside
the occupant compartment on rebound, so there was no contact between the head and side airbag.
Both the Outlander Sport and Escape allowed too much intrusion into
the occupant compartment on the right side.
The passenger - side door sill was pushed 4 inches laterally into
the occupant compartment.
Intrusion into
the occupant compartment was extensive.

the occupant compartment.
Across the board, the Outlander Sport received a marginal rating and the Ford Escape earned a poor rating in part for allowing «too much intrusion into
the occupant compartment» on the passenger - side, IIHS said.
«The space around the driver dummy was well maintained, and there was minimal intrusion into
the occupant compartment.
There was more intrusion into
the occupant compartment than in many of the other vehicles tested.
Other injury measures also were low, and the Prius's structure held up with minimal intrusion into
the occupant compartment.
The occupant compartment did a good job of preventing major intrusion during the test.
There was little intrusion into
the occupant compartment.
Some intrusion into
the occupant compartment is inevitable in serious side impacts.
This contrasts with a serious frontal crash, in which the whole length of a vehicle's front end crushes to help protect the people riding in
the occupant compartment,» Lund points out.
(3) Structural performance is based on measurements indicating the amount of intrusion into
the occupant compartment around the B - pillar (between the doors).
