A retention mechanism for a hinge mechanism of a door, the hinge mechanism being configured for articulating a door to the sidewall of a vehicle so as to enable pivoting of the door relative to the sidewall about an axis between a closed position and an open position, the retention mechanism comprising:

• a. a first portion comprising a keeper and a biasing arrangement configured to bias the keeper toward a locking position, while allowing displacement of the keeper from the locking position to a disengaged position;
• b. a second portion comprising a latch, the latch being configured to displace the keeper from its locking position to its disengaged position and comprising a seat for retaining the keeper therein in its locking position, so as to maintain the door in its open position when the keeper being retained in the seat;
• wherein the retention mechanism, when operating in conjunction with the hinge mechanism, comprises a clearance area in which, during pivoting of the door between its closed and open positions, there is no contact between the keeper and the latch.
