Claim:
1. A lift mechanism for lifting and lowering a support member in an interior of a vehicle, the lift mechanism comprising: a frame connected to the support member so the support member is movable vertically relative to the frame; a drive unit that drives the support member to lift the support member relative to the frame and control descent of the support member relative to the frame; a switch that is actuated to energize the drive unit and thereby to cause the drive unit to lift the support member to a first position or lower the support member to a second position; at least one pin to secure the support member relative to the frame in at least one of the first position and the second position; wherein after the switch is released; the drive unit stays energized for a predetermined period of time so as to hold the support member at the elevation the support member is in at the time the switch is released and to prevent creeping of the support member with respect to the frame under the influence of gravity to allow for insertion of the pin.
