A vehicle frame includes a first beam with a first wall and a second wall extended in a first beam longitudinal direction, wherein the first wall and the second wall are spaced from each other in a first beam transverse direction substantially perpendicular to the first beam longitudinal direction. The first beam includes at least one first beam reinforcement structure, the at least one first beam reinforcement structure including a first leg and a second leg disposed along the first beam and extended between the first wall and the second wall in the first beam transverse direction. The first leg and the second leg are angled toward each other along the first beam transverse direction from the second wall toward the first wall.

An assembly for a vehicle includes a vehicle body including a sill and a pillar extending upwardly from the sill defining a door opening. A member is rotatably supported by the sill and is rotatable relative to the sill from an undeployed position to a deployed position. A link is rotatably supported by the pillar and the member. A pyrotechnic actuator is supported by the vehicle body and is connected to the member.

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 vehicle frame structural member assembly method includes an elongated frame member and a reinforcement member. The reinforcement member is complementarily arranged adjacent the elongated frame member.

A shock-absorbing unit may include a reinforcement part made of a composite material, which has a panel shape, two opposing end portions of which are connected to the inner panel to divide the inner space into a separation space adjacent to the outer panel and a partition space adjacent to the inner panel, and which has a coupling protrusion protruding from the inner surface thereof toward the inner panel, and a shock-absorbing part made of a composite material, which has a coupling recess formed in one side thereof to receive the coupling protrusion so as to be connected to the reinforcement part in the partition space, and the opposite side of which is connected to the inner surface of the inner panel and is supported by the inner panel.

A vehicle includes a vehicle body including: an elongated frame made of a first material and extending along a door opening; and an elongated rail made of a second material having a linear expansion coefficient different from that of the first material, the rail covering the frame and extending along the frame, the rail being configured to abut with a weather strip when a door closes the door opening. The rail is fixed to the frame at a plurality of fixation parts that includes: a first fixation part provided in an intermediate part of the rail in the longitudinal direction of the rail; and second fixation parts provided, respectively, in opposite end parts of the rail in its longitudinal direction. In the longitudinal direction of the rail, backlash widths at the second fixation parts are larger than a backlash width at the first fixation part.

A vehicle includes a first pillar and a second pillar spaced from the first pillar along a vehicle-longitudinal axis. A rotational actuator is disposed at the first pillar. The rotational actuator is fixed relative to the first pillar. A cable is engaged with the rotational actuator and is elongated along the vehicle-longitudinal axis to the second pillar. The cable is moveable to a deployed position by the rotational actuator and is under tension in the deployed position.

A method for manufacturing a unitary body side structural frame for a vehicle is provided. The method comprises providing a plurality of blanks, joining the blanks to each other to form a composite blank wherein joining the blanks includes forming one or more overlapping regions formed by partially overlapping two blanks and deforming the composite blank to form the unitary body side structural frame. A unitary body side structural frame as obtained by any of the methods herein described is also provided.
