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. The magnetic head includes a write head provided with a main pole and one or more auxiliary poles, a read head provided with a read element, and coils located on both sides of the main pole in a manner to sandwich the main pole. When the car is stolen, the owner can activate the signal code, which will disable the engine once the thief turns off the engine. The engaging portion is also engaged with the notch of the card in this first position, but the release of the engagement is allowed by the wall portion, and the card can be pulled out by elastically deforming the spring portion. Thereby, it is possible to widen the laser energy measuring range. The surface film can be located on a carrier, sealing or trim portion of the weatherseal, wherein the surface film can be colored, and selected to provide a desired surface characteristic such as reduced coefficient of friction.
