A barrier may be configured to maintain a fixed position with respect to a seat, the barrier separating a first space from a second space, a seatbelt buckle may be configured to maintain a fixed position with respect to the barrier in the second space, the buckle includes an opening to receive a seatbelt tongue and a release button to release the tongue from the buckle, the barrier may include a slot having dimensions selected to permit passage of the tongue from the first space into the opening and prevent an object from passing through the slot to operate the release button. A force-transfer-structure, coupled between the release button and a solenoid may transfer a force exerted by the solenoid to the release button, where the buckle and force-transfer-structure maintain operational alignment therebetween. A second structure can operate the release button in event that the solenoid is inoperable.
