The arm has a square tubular member 1 with an end stopper member 3 which inserting square member 2 through and into tubing 1. The inserting solid or tubular member 2 has at the end a solid square head 20 connected which slides inside of tubular member 1 and is arrested by stopper member 3. The inserting member 2 has a lock mechanism 5 pivotally connected by pin 18. The lock mechanism 5 has a semi-circular rod 4 pivotally connected by pin 8 and locks on to lock mechanism 5 by lock 7 with key hole 25. A bolt 10 is permanently connected to the hump A of the motor-car floor by two nuts 12 and 13 which are preferably welded to the floor hump A and to

the bolt 10. A U-shaped member 9 is pivotally connected to the bolt 10. The arm tubing 1 permanently and pivotally is connected at one end to the U-shaped member 9 by pin 11. A cover 14 is connected on the floor hump A by hinges 16 and preferably pivots 19. The cover 14 has handle 15 and hook 17 which engages hole 18. Figure 2 shows the security arm extended and locked on the steering-wheel 22 which has cross member 23 which cannot cross the lock mechanism 5. The security arm can also be connected to the flat section of the motor-car floor B near the seat 24.

The security arm has a circular tubing- 26 and a inserting rod 28 which has a hook at one end slides into the tubing 26. The inserting rod 28 has teethes which lock 31 engages the gaps between the teethes to arrest the inserting rod not to move in or out of tubing 26. A bolt 33 is fixed onto the floor hump A with nuts 34 and 35 by same method as explained for Figs. 1 and 2. A U-shaped member 36 is pivotally connected to bolt 33 and a lock with shaft 32 that passes through the ends of the U-shaped member 36 has a short piece of tubing 27 which the shaft 32 also passes through. The tubular arm member 26 connected at one end to the tubing member 27 by preferably weld method. When the security arm is unhooked from the steering-wheel 22 it is pivoted into the foam or rubber mould 37 which holds the security arm firmly in place. The security arm can be detached from the U-shaped member 36 by unlocking and removing the lock 30 from the U-

shaped member 36. The security arm can also be hooked onto the T-bar 38 of the automatic transmission. The security arm can also be hooked on the manual arm lever if the motor-car is manual (not illustrated) .

Fig. 40 shows alternative arrangement, design and mechanism for the security apparatus. A length of wire 370 is used which a hook 371 is connected at one end and is connected at the other end to a spring loaded wheel 374. A U- shaped rod 376 is connected under the hump surface 374 which wheel 374 rotates about the base of the U-shaped rod 376. The wire 370 is guided by rollers 372 and 373 which structure 383 supports the rollers 372 and 373. The spring loaded wheel 374 has gearing 375 which gadget 377 pivotable about 382 engages gearing 375 to arrest the wheel 374. The lock 378 with key hole 379 locks and unlocks the gadget 377 in the gearing 375. The finger hook 384 is hooked on roller 372 when the security wire is not in use. When the hook 371 is in case 380 with spring load wheel 374 unlocked the security wire is pulled out of the case 380 and hooked on the steering-wheel 22, then the key is turned to lock the gadget 377 in gearing 375 to arrest the spring loaded wheel 374 from turning. This security wire can be hooked on to the T-bar 381 or manual lever or hand-brake lever. This security wire can also be hooked on to any interior member of the car.

Fig. 41 shows a portable spring loaded chain were the case 386 is shaped in a hook form as shown. The chain 315 is wound around wheel 343 and is connected to the wheel 385. The spring 341 is connected to the wheel and to the fixed axle 383. The chain 315 can also be a wire. The casing 386 can be hooked on the foot brake and the chain pulled from of the casing and locked onto the steering-wheel.
