The 2016 Lexus RX body structure uses of high-tech body adhesives and laser screw welding; liberal use of high-tensile strength steel throughout the vehicle including key areas such as the underbody cross members and front (A-pillar) and middle (B-pillar) sections; the implementation of a new process called “annular frame construction” for strengthened frame sections within the vehicle around the front and rear doors; and redesigned body frame sections and additional spot welds around the rear portion of the vehicle for improved strength and handling stability. Notice the stronger steel used in the typical locations in addition to the C-pillar.
High-tensile strength steel is used liberally throughout the vehicle (sections coloured orange in image above), including key areas such as the cross members (image below is the cross member between A-pillar and front cowl) and pillars. These form part of a new building process called annular frame construction, which reinforces the vital ring around the doors for improved strength.
The front-passenger seat is designed to detect whether the seat is occupied by an adult or a child, or is vacant. In case the system detects a child or empty passenger seat, it prevents the passenger’s front, side and cushion airbagsfrom being deployed. The front passenger’s airbag features two chambers, creating an indentation in the center impact area that helps to provide occupant protection in a severe frontal collision.
