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.

An assembly includes a vehicle body including a door opening and a first member and a second member each supported by the vehicle body. The first member and the second member are rotatable relative to each other and relative to the vehicle body across the door opening from an undeployed position to deployed position. The first member and the second member engage each other in the deployed position.

A vehicle-door reinforcement includes a first beam elongated along an axis between a first end and a second end. The vehicle-door reinforcement includes a hinged beam elongated along the axis. The hinged beam includes a first segment and a second segment hinged to each other. The first segment is engaged with the first beam and the second segment is slideably engaged with the first beam. The vehicle-door reinforcement includes an actuator fixed to the first beam and connected to the second segment.

A side impact restraint protection system for a vehicle includes first and second side safety structures and first and second structural elements of a vehicle body structure. The first and second side safety structures are respectively connected to a first side door and a second side door. The first and second side doors are arranged to cover a common single door opening of the vehicle body structure. The first structural element is in a position in front of the door opening and the second structural element is in a position behind the door opening in a longitudinal direction. In the closed door position, the first and second side safety structures are releasably connected to each other via a connecting device, and the first and second side safety structures are respectively connected to the first and second structural elements via a first connection member and a second connection member.

A side body vehicle structure is disclosed that has a pair of left and right side sills and opposite swing type side doors. The side sills may have an upper flange portion facing the rear door in the vehicle width direction which functions as a rear door facing part, and the upper flange portion of a more forward part of the vehicle than the rear door facing part may function as a front door facing part. The rear door facing part may be formed in a shape having a length in the vehicle vertical direction longer than a length in a vehicle vertical direction of the front door facing part. In a vertical cross section along the vehicle width direction, a gusset member may form a closed cross section with the side sill inner member, and an upper end thereof may be joined to the rear door facing part.

A vehicle includes a first pillar. The vehicle includes a second pillar having a distal end and spaced from the first pillar. The vehicle includes an extendible member supported by the first pillar and moveable from a retracted position where the extendible member has a first length to an extended position where the extendible member extends to the second pillar spaced from the distal end and has a second length greater than the first length.
