Impact Absorbing Structure for Side Collision

The impact energy of a side collision directed to the cabin area is dispersed throughout the body via the pillar reinforcements, side impact protection beams, and floor cross members, thus helping minimize the impact energy finally directed to the cabin.

► In order to obtain optimal bearing force, ultra high strength sheet steel is employed in the center pillar reinforcement as described on page BO-2, furthermore, box-shaped reinforcement is used inside the center pillar (A - A cross section).

► Ultra high strength sheet steel is used in the roof reinforcement. In addition, the structure has been made to bear impact loads with both side rails (B - B cross section). This reduces the intrusion of the roof rail into the cabin in the event of a side collision.

► A bulk is used for the rear door inner and a gusset is used for the center floor cross member on the cabin interior side. When a side collision occurs, loads are conducted from the bulk to the gusset, deformation of the vehicle body is minimized (C - C cross section).

► Seat pipes and seat pads have been provided on the front seat pillar frame for load conduction. Furthermore, the tunnel box has been reinforced. Thus, input load is conducted from the pillar and door to the seat, tunnel box and opposite seat, minimizing deformation of the body.

► A head impact protection structure is used. With this type of construction, if the occupant's head hits against the roof side rail or pillar due to a collision, the inner panels of the roof side rail, roof area and pillar collapse to help reduce the impact.
