E93 Complete Vehicle Workbook
Passive Safety Systems
In the same way as the Sedan, the E93 Convertible offers vehicle safety at the highest level for all occupants as well as in all crash situa-
tions. Numerous reinforcements have been implemented in the body for the purpose of conforming to worldwide stipulations relating to a
uniform body.
The loads and stresses that occur in the case of a crash are counteracted by a reinforced floor assembly and a reinforced bulkhead with
high-strength A-pillars. The reinforced floor assembly is required particularly in the area of the front seats in order to direct the forces that
are exerted in the event of a crash by the seat integrated seat belt systems into the floor assembly.
The sills were reinforced specifically for the Convertible in order to be able to absorb the forces in the event of a side crash and to direct
them to the opposite side of the impact. The roof frame in the area of the windshield has been reinforced and forms the rollover protection
system together with the roll bars integrated in the partition module.
In the event of a crash, in which the vehicle rolls over, the roll bars extend in milliseconds and, together with the roof frame, form an
adequate survival space for the occupants.
The E93 Convertible is equipped with a passive safety system with rollover protection. In the event of a crash, in which the vehicle rolls
over, the roll bars extend automatically and, together with the windshield frame form an adequate survival space for the occupants.
The rollov
er sensor system is integrated in the crash safety module. The actuators are triggered by the ROC control unit. In the event of a
side crash, an enlarged side airbag located in the backrest protects the thorax and head of the occupants.
