Door e.g. front side door, arrangement for vehicle e.g. passenger car, has impact carrier and inner belt line reinforcement, which are made of steel with smaller linear extension coefficients than door outer plate

摘要

The arrangement has a door inner plate (18) with one-sided and two-sided attachment sections at two sides in a thickness direction of a door (42). A door outer plate (20) is arranged close to one of the sides and attached to the inner plate. An impact carrier (26) and an inner belt line reinforcement (44) are made of steel with smaller linear extension coefficients than the outer plate and are arranged between the plates. The carrier and reinforcement are arranged at areas at the sides, respectively, where sections against two ends in a door width direction are attached to the sections.
