Disclosed is a method of use of a movable seat for a law enforcement vehicle. A method of restraining a detainee within a vehicle may include the steps of: opening a door on a vehicle comprising a movable seat; retracting the movable seat from a first position in the vehicle to a second position adjacent the door of the vehicle; seating a detainee in the movable seat of the vehicle; wherein the detainee's hands are restrained behind its back; positioning the detainee's hands in an opening in a back of the movable seat; restraining the detainee in the movable seat with a seat belt coupled to the movable seat; returning the movable seat to the first position inside the vehicle; and closing the door on the vehicle.

A supplemental restraint system that is mountable to the frame of a stationary structure, such as a police station or other building, to secure a prisoner in a seated position. The supplemental restraint system includes a restraint bar that is pivotally supported on the mounting plate for movement between a raised inoperative position and a lowered operative position. A locking mechanism secures the restraint bar in any selected lowered position and includes an actuation lever for selectively releasing the locking mechanism to permit the restraint bar to be raised for release of the prisoner. A spring mechanism biases the restraint bar toward a raised position so that the restraint bar can be moved upwardly while the police officer is outside of the police vehicle. Mounting plates can be utilized to secure the supplemental restraint system to the floor structure and an adjacent wall structure.

Disclosed is a movable seat for use in a law enforcement vehicle. The vehicle seat may include a seat comprising a seat back and a seat bottom. A track system is coupled to the seat and to a vehicle mount. At least one restraint is also coupled to the seat. The at least one restraint may be a four point harness. An opening is also formed in the seat back in order to receive the restrained hands of an uncooperative passenger. The seat may move along the track system, allowing the seat to move completely out of the vehicle thereby allowing a passenger to be safely restrained in the seat while still outside the vehicle. The seat is moved back into the vehicle along the track system.

A seat for use in a passenger vehicle, e.g. for prisoner transport, comprises a molded piece having at least one first contact zone at a periphery of the molded piece and at least second contact zone located inward of the periphery of molded piece. The second contact zone may comprise a multi-surface formation that is configured to engage a multi-surface formation of a vehicle body. The molded piece may comprise one or more recesses designed to accommodate the body of a passenger. The at least one second contact zone may be disposed in an area of the seat that receives the buttocks of a passenger, thereby providing additional support in a load bearing area of the seat.
