Support structure for vehicle, has transition zone whose resistance value is reduced to predefined value, such that continuous curve is formed from high resistance value in hard portion down to low-resistance value in soft portion

摘要

The support structure (1) has a hard portion (3) that is provided with high resistance value. A soft portion (5) having a lower resistance value is formed along longitudinal extension direction (x) of supporting structure main portion. An intermediate transition zone (7) is formed between hard portion and soft portion. The resistance value of the transition zone is reduced to a predefined value, such that continuous curve is formed from the high resistance value in the hard portion down to the low-resistance value in the soft portion. An independent claim is included for a method for manufacturing support structure.
