Unit with longitudinal beam and front plate for a motor-vehicle front structure, comprising a longitudinal beam in the form of a hollow profile and a front plate rigidly connected to a front end of said longitudinal beam. The longitudinal beam comprises a first beam element defining an upper wall, a lower wall and a first side wall of the longitudinal beam and a second beam element having a wall defining a second side wall of the longitudinal beam. The front plate has a rear face facing towards the longitudinal beam to which there are welded a first flange and a second flange which are separate from each other, for connecting the front end of the longitudinal beam. The first flange is a C-shaped bracket with an upper wall, a lower wall and a side wall respectively welded to the upper wall, the lower wall and the first side wall defined by said first beam element. The second flange is an L-shaped bracket, with a first wall welded to the rear face of the front plate and a second wall facing towards said second side wall defined by said second beam element. The above mentioned welds are electric spot welds. The two flanges may have different thickness.

The invention provides a method of assembling a roof of a cargo body. A plurality of sidewalls are provided, each comprising a side panel and an upper rail coupled to the side panel. A roof panel is located above the plurality of sidewalls adjacent the upper rails. A roof bow extends between the upper rails below the roof panel. The roof bow is fixed to a track of one of the upper rails with a fastener.

A seamless unibody structure of C-pillar for vehicles is envisaged. The seamless unibody structure has an operative top end and an operative bottom end, and is defined by a C-pillar inner, a C-pillar extension portion and a wheel house inner. The C-pillar inner extends from the operative top end. The C-pillar extension portion extends integrally from the C-pillar inner, and the wheel house inner extends integrally from the C-pillar extension portion.

A reinforcement element has a carrier having a longitudinal axis and elongate opening extending in the axis direction. The reinforcement element has an insert element having a longitudinal axis constructed to be arranged in the elongate opening. The insert element has first and second portions. The first portions are parallel with a first plane. The insert element longitudinal axis is in this first plane. The second portions are parallel with a second plane. The insert element longitudinal axis is in the second plane. The reinforcement element has a first adhesive which can be arranged on the carrier outer side and on a first group of insert element first portions and to bond the carrier and insert element in the structural element. The reinforcement element has a second adhesive which can be arranged on a second group of insert element first portions and to bond the insert element in the carrier.

A vehicle front portion structure includes: a battery case that is installed beneath a floor of a vehicle; front side members that extend in a vehicle longitudinal direction further toward a vehicle front side than the battery case; side rails that structure portions of a suspension member that is disposed further toward the vehicle front side, and that extend in the vehicle longitudinal direction; first connecting members that connect the battery case and the front side members; and second connecting members that connect a vehicle longitudinal direction front end portion of the battery case and vehicle longitudinal direction rear ends of the side rails, that face the battery case in the vehicle longitudinal direction as seen in a plan view and in a side view, and that face the side rails in the vehicle longitudinal direction as seen in a plan view and in a side view.

A rollover device for a passenger compartment of a motor vehicle includes a plurality of struts made of fiber-reinforced plastic, and a plurality of fastening feet made of metallic material for connecting the rollover device to a vehicle body. At least one fastening foot made of metallic material is connected to a respective strut made of fiber-reinforced plastic via a material-locking connection on the one hand and via a form-locking connection on the other hand.
