Method for manufacturing an underrun protection device for a vehicle as well as modular system for a plurality of variance of an underrun protection device

摘要

A method for manufacturing an underrun protection device 10 for a vehicle, in particular a commercial vehicle such as a truck, comprises: providing a center member 12; providing a first lateral member 14 slidably arranged on a first side 18 of the center member 12 and a second lateral member 16slidably arranged on an opposite second side 22 of the center member 12; adjusting the length of the underrun protection device 10 on the basis of a width of the vehicle by sliding the lateral members 14, 16 in relation to the center member 12 thereby sliding the lateral members 14, 16 into respective positions; and fixing (e.g. by welding, bolting, riveting, brazing or adhesive joining) the lateral members 14, 16 being in the respective positions to the center member 12. Lateral members 14, 16 may be telescopically arranged on the center member 12 and may each comprise respective shell elements (28, 30) connectable together to form at least one closed hollow cross section.
