A door frame for a vehicle includes an inboard panel that includes an outer peripheral wall, an inner peripheral wall spaced apart from the outer peripheral wall, and an inboard side wall connecting the outer peripheral wall and the inner peripheral wall. The outer peripheral wall extends obliquely from the inboard side wall at a predetermined angle. The doorframe also includes an outboard panel coupled to the inboard panel. The outer peripheral wall has a mounting hole for mounting a door weatherstrip.

A barrier door for a protective enclosure includes a lower section and an upper section operably coupled with the lower section, and a ventilation system disposed within the lower section. The ventilation system includes one or more blowers and a plenum. The ventilation system is configured to direct air one or more of into or out of the protective enclosure.

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 surveillance equipment platform mounting in an interior cabin of a vehicle. The interior cabin of the vehicle has a roof with an opening. The surveillance equipment platform includes a retractable telescoping structure having surveillance equipment mounted so as to extend through the opening of the roof, and to fully retract into the interior cabin. The surveillance equipment platform also includes a sealing device that mounts to the retractable telescoping structure below the surveillance equipment and oriented parallel to the roof of the interior cabin. The sealing device includes an elastically deformable gasket that elastically deforms during travel of the sealing device through the roof of the interior cabin when the surveillance equipment extends through the opening in the roof during extension of the retractable telescoping structure, and when the surveillance equipment retracts into the interior cabin during retraction of the retractable telescoping structure.

An adjustment assembly for use in a vehicle, including an adjustable part configured to move between an open position and a closed with respect to a vehicle body. The adjustable part may include an outer side and an inner side. At least a portion of the adjustable part may define an opening extending between the outer side and the inner side. The adjustment assembly may include an ultrasonic transmitter, disposed on either the adjustable part or the vehicle body and may be configured to emit a number of ultrasonic waves to an obstacle, and an ultrasonic receiver disposed on the inner side of the adjustable part and configured to receive the ultrasonic waves reflected from the obstacle through the opening.

A seal for a vehicle door. The seal includes a lower seal member structured to be mounted to a lower vehicle door portion and an upper seal member structured to be mounted to an upper vehicle door portion. The upper seal member sealingly contacts the lower seal member when the upper vehicle door portion is mounted to the lower vehicle door portion. The lower seal member includes a projection structured to abut a portion of the lower vehicle door portion when the lower seal member is mounted to the lower vehicle door portion, so as to prevent a movement of the lower seal member and resulting misalignment between the upper and lower seal members during movement of the seal members into sealing contact with each other.
