fig2 3 when the invention is in the inactive mode the shaft and spool assembly rides on the two bearing assemblies fig2 4 a b to allow free movement of the shaft in either direction when the invention is in the inactive mode the electromagnetic brake assembly fig2 2 a b is a two piece device consisting of an electromagnet fig2 2 b that is attached to the case assembly fig2 1 the second part of the electromagnetic brake assembly figs 2 2 a is attached to the shaft with a set screw and rotates with the shaft without interference from electromagnet fig2 2 b while the invention is in the inactive mode when voltage is applied active mode to the electromagnetic brake assembly fig2 2 a b part fig2 2 b produces an electromagnetic force that pulls the friction material of electromagnetic brake assembly fig2 2 a into physical contact with electromagnetic brake assembly part fig2 2 b this binds the electromagnetic brake assembly fig2 2 a which is attached to the shaft and spool assembly fig2 5 to the electromagnetic brake assembly fig2 2 b which is attached to the case assembly fig2 1 this renders the shaft and spool assembly fig2 5 locked and immoveable preventing the strap assembly fig2 3 from being pulled out of the case assembly fig2 1 as shown in fig3 the retractable restraint fig1 1 is mounted fig3 3 to the backside of the front passenger seat the strap assembly fig3 2 is passed through the gap between.
