Adjustable door assembly for vehicle door, ventilation system for off-road vehicle including same, and vehicle

An adjustable door assembly comprising:

• a striker;
• and
• an adjustable mechanism connected to the striker and configured to move the striker to any of a plurality of positions that range from a first position through a second position, the adjustable mechanism includes,
• a pinion gear,
• a rack gear engaging the pinion gear, the striker is mounted onto the rack gear, the pinion gear selectively drives the rack gear to move the striker between the first position and the second position, and
• a knob coupled to the pinion gear and selectively rotating the pinion gear to drive the rack gear.

A ventilation system for an off-road vehicle having a passenger space and a frame assembly, the frame assembly bounding the passenger space and defining an opening for a passenger to ingress to the passenger space and egress from the passenger space, the ventilation system comprising:

• a striker configured to be movably connected to the frame assembly and selectively movable between a first position and a second position;
• a door pivotally mounted on the frame assembly and movable between a plurality of positions ranging from a closed position through an opened position, the plurality of positions includes at least one venting position,
• the door is in the closed position when the door is latched onto the striker and the striker is in the first position, such that the door obstructs ingress and egress through the opening when the door is in the closed position,
• the door is in the opened position when the door is released from the striker and spaced away from the striker, such that the door permits ingress and egress through the opening when the door is in the opened position,
• the door is in the venting position when the door is latched to the striker and the striker is in the second position;
• and
• a vent extending through the door,
• the vent is exposed to air outside of the off-road vehicle and directs the air outside of the off-road vehicle into the passenger space when the door is in the venting position, and
• the vent is closed to the air outside of the off-road vehicle when the door is in the closed position.

A vehicle comprising:

• a passenger space;
• a frame assembly bounding the passenger space and including an A-pillar, a B-pillar and an opening bordered by the A-pillar and the B-pillar;
• a body panel supported by the A-pillar and extending along the opening;
• a door including a front end and a rear end;
• a hinge connecting the rear end of the door to the B-pillar, the door pivots about the hinge between a closed position in which the door obstructs ingress to and egress from the passenger space through the opening and an opened position in which door permits ingress to and egress from the passenger space through the opening;
• a lock located adjacent the A-pillar and movable through a plurality of venting positions that range from a first position through a second position, the lock includes a locked state in which the lock holds the front end of the door in a selected one of the venting positions, the lock includes an unlocked state in which the front end of the door is released and freely pivots between the opened position and the closed position;
• and
• a vent passing through the door, the vent is exposed to air flowing outside of the off-road vehicle and directs the air flowing outside the off-road vehicle into the passenger space when the lock is in the locked state and spaced away from the first position, and the body panel closes the vent to the air flowing outside of the off-road vehicle when the lock is in the locked state and in the first position.
