Abstract: A prisoner seat security device includes a retractable strap which hooks or clasps onto a prisoner, preferably by a restraint device on the prisoner, such as hand-cuffs. As the prison seats in the seat, the strap retracts. The officer can then lock the retraction mechanism so that the strap will not extend and the prisoner is held in place. When it is desired for the prisoner to get out of the chair, the lock is released, allowing the prisoner to stand the strap to be disconnected.

Abstract: A device to restrain a prisoner has a nylon strap attached to a spring-loaded spool, which the operator attaches by means of a clasp to the prisoner's handcuffs or restraining apparatus, and the nylon strap automatically retracts through the seat into the spool's housing located behind the seat as the prisoner sits down. When the prisoner is seated against the seatback, the law enforcement officer activates a remote-control locking switch, which causes a 12-volt braking mechanism to engage and prevent the nylon strap from being pulled out, which holds the prisoner securely in place against the seat and prevents him/her from being able to move enough to release a seatbelt or unlock and open a vehicle door. When the officer is ready to remove the prisoner, he/she again activates the remote-controlled switch which releases the brake and allows the nylon strap to be extracted while the prisoner steps away from the seat.
