The Chevrolet Blazer and GMC Jimmy were redesigned for the 1995 model year, the Oldsmobile Bravada was redesigned for 1996, and the GMC Envoy was introduced in 1998.
Injury measures
Measures taken from the chest and left leg indicate low risk of injuries to these body regions in a crash of this severity. Forces on the head when the dummy moved forward into the airbag indicate that injuries to the head would be possible. A high head acceleration occurred when the dummy's head hit the window sill/B-pillar, indicating that further injuries to the head would be possible. Forces on the right tibia and acceleration on the right foot indicate that injuries to the lower leg and foot would be possible.
Restraints and dummy kinematics
Dummy movement wasn't well controlled. As the dummy moved into the airbag, its torso rolled off the bag toward the driver door. Its head hit the window sill, denting it, then hit the B-pillar. Also, there was too much upward movement of the steering column.
