Patents Act 1990 COMPLETE SPECIFICATION Invention Title: Theftproof System for Automobile The following statement is a full description of this invention, including the best method of performing it known to me: 03/07/00 17:02 I THEFTPROOF SYSTEM FOR AUTOMOBILE 2 BACKGROUND OF THE INVENTION 3 FIELD OF THE INVENTION 4 The present invention relates to a theftproof system, and more particularly to a theftproof system for an automobile.

6 DESCRIPTION OF THE RELATED ART 7 A conventional theftproof device for a car in accordance with the 8 prior art comprises a lock mounted on the steering wheel or the gear shift stick 9 of the car so that the steering wheel or the gear shift stick is fixed and cannot be moved, thereby achieving a theftproof function.

11 A conventional theftproof device for the driver's seat of a car in 12 accordance with the prior art comprises a movable seat which can be moved to 13 the front end of the driver's seat for blocking the leg placing space of the 14 driver's seat so that an extruder cannot step on the clutch pedal, the brake pedal or the accelerator pedal of the driver's seat. A lock can be used to secure the 16 seat when the seat is moved to its front end, thereby efficiently achieving a 17 theftproof function. However, the user has to push the seat forward and then 18 lock the seat by the lock manually, thereby causing inconvenience to the user, 19 and thereby wasting energy. In addition, the lock is exposed outward from the seat so that the lock is easily broken by the thief, thereby greatly decreasing the 21 theftproof effect. 22 SUMMARY OF THE INVENTION 23 The present invention has arisen to mitigate and/or obviate the 24 disadvantage of the conventional theftproof device for a car.

In accordance with one aspect of the present invention, there is 26 provided a theftproof system for an automobile comprising: an elongated slide 27 track mounted on a drives seat of an automobile; a seat slidably mounted on 28 the slide track; a seat motor mounted on the slide track for driving the seat to 29 move reciprocally on the slide track; a reduction gear set mounted on the slide track and co-operating with the seat motor to move the seat; and a seat rU I movement control device mounted in the automobile for operating the seat 2 motor to rotate and including a receiver, a central processing unit, a decoder, an 3 actuator, and a motor rotation control circuit. The seat movement control 4 device is preferably provided with a power supply by a battery and is adapted to co-operate with an emitter. The motor rotation control circuit of the seat 6 movement control device can be electrically connected to the seat motor for 7 rotating the seat motor.

8 By such an arrangement, when the receiver receives the signal 9 supplied from the emitter remotely, the motor rotation control circuit of the seat movement control device is adapted to actuate the seat motor to rotate 11 positively so as to move the seat on the slide track to a front end of the driver's 12 seat, thereby blocking and sealing a leg placing space of the driveis seat so that 13 an 4itruder cannot step on a pedal of the driver's seat.

14 A steering wheel is pivotally mounted in the automobile, and a steering wheel motor and a reduction gear set are mounted in the automobile 16 for controlling the steering wheel to pivot relative to the seat reciprocally.

17 Preferably, the steering wheel motor is electrically connected to the motor 18 rotation control circuit so that when the seat is moved forward, the steering 19 wheel is synchronously pivoted downward, thereby further blocking and sealing the leg placing space of the drivers seat.

21 Further benefits and advantages of the present invention will become 22 apparent after a careful reading of the detailed description with appropriate 23 reference to the accompanying drawings.

24 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a partially enlarged schematic view of a theftproof system 26 for an automobile in accordance with the present invention; 27 Fig. 2 is an operational view of the theftproof system as shown in Fig.

28 1; 29 Fig. 3 is a flow chart of a seat movement control device of the theftproof system as shown in Fig. 1; 1 Fig. 4 is a flow chart of a seat movement control device of the 2 theftproof system as shown in Fig. 1 in accordance with another embodiment 3 of the present invention; 4 Fig. 5 is a schematic practice view of the theftproof system as shown in Fig. 1;and 6 Fig. 6 is an operational view of the theftproof system as shown in Fig.

7 8 DETAILED DESCRIPTION OF THE INVENTION 9 Referring to the drawings and initially to Figs. 1-4, a theftproof system for an automobile in accordance with the present invention comprises 11 an elongated slide track 10 mounted on a drives seat 18 of an automobile, a 12 seat 11 slidably mounted on the slide track 10, a seat motor 12 mounted on the 13 slide track 10 for driving the seat 11 to move reciprocally on the slide track 14 a reduction gear set 120 mounted on the slide track 10 and co-operating with the seat motor 12 to move the seat 11, and a seat movement control device 16 mounted in the automobile under the seat 11 for operating the seat motor 12 to 17 rotate.

18 The seat movement control device 20 includes a receiver 21, a 19 central processing unit 22, a decoder 23, an actuator 24, and a motor rotation control circuit 25, wherein the motor rotation control circuit 25 is 21 electrically connected to the seat motor 12 for rotating the seat motor 12.

22 The seat movement control device 20 is provided with a power 23 supply by a battery 26, and the receiver 21 of the seat movement control device 24 20 is adapted to co-operate with an emitter 27.

In operation, referring to Figs. 1-6, when the driver gets off the car, 26 he can press the emitter 27 so as to remotely emit a signal to the receiver 21.

27 When the receiver 21 receives the signal supplied from the emitter 27 remotely, 28 the motor rotation control circuit 25 of the seat movement control device 20 is 29 adapted to actuate the seat motor 12 to rotate positively so as to move the seat 11 on the slide track 10 from the position as shown in Figs. I and 5 to the I position as shown in Figs. 2 and 6 s0 that the seat I I is displaced to the front 2 end of the driver's seat 18, thereby completely blocking and sealing the leg 3 placing space 15 of the drive~s seat 18 s0 that an o"Ktruder cannot step on the 4 pedal 16 of the driver's seat 18, thereby achieving a theftproof function. The pedal. 16 may be a clutch pedal, a brake pedal or an accelerator pedal.

6 On the other hand, a steering wheel 13 is pivotally mounted in the 7 automobile. A steering wheel motor 14 co-operating with a reduction gear set 8 140 is mounted in the automobile for controlling the steering wheel 13 to pivot 9 relative to the seat 11I reciprocally. The steering wheel motor 14 is electrically connected to the motor rotation control circuit 2 5 so that when the seat I I is I1I moved forward, the steering wheel motor 14 is rotated positively by the motor 12 rotation control circuit 25 to pivot the steering wheel 13 so that the steering 13 wheel 13 can be synchronously pivoted downward when the seat 11I is moved 14 forward, thereby fuirther blocking and sealing the leg placing space 15 of the driver's seat 18.

16 As shown in Figs. 1 and 5, for a common use, the leg placing space 17 15 of the drive~s seat 18 is large enough to accommodate the driveis legs for 18 controlling the pedal 16 such as a clutch pedal, a brake pedal or an accelerator 19 pedal.

As shown in Figs. 2 and 6, when the driver gets off the car, he can 21 press the emitter 27 to remotely emit a cutoff signal to the receiver 2 1. When 22 the receiver 21 mounted on the car receives the signal from the emitter 27, the 23 signal is processed by the C.P.U. 22 and the decoder 23 so as to drive the 24 actuator 24 which controls the motor rotation control circuit 25 which then actuates the seat motor 12 and the steering wheel motor 14 to rotate positively 26 so that the seat 11I can be moved forward on the slide track 10, and the steering 27 wheel 13 can be synchronously pivoted downward when the seat 11I is moved 28 forward, thereby completely blocking and sealing the leg placing space 15 of 29 the drive~s seat 18. The seat motor 12 and the steering wheel motor 14 then stop rotating when the leg placing space 15 of the driver's seat 18 is entirely 1 blocked. At the same time, the seat motor 12 is locked by the reduction gear set 2 120, and the steering wheel motor 14 is locked by the reduction gear set 140 so 3 that the ctruder cannot easily push the seat 11 and the steering wheel 13 to 4 their original positions, thereby achieving a theftproof function.

Accordingly, the theftproof system in accordance with the present 6 invention has the following advantages.

7 The driver only needs to press the button of the emitter so as to move 8 the seat or to pivot the steering wheel for blocking the leg placing space of the 9 driver's seat, thereby facilitating the operation of the theftproof system.

In addition, the driver only needs to press the button of the emitter so 11 as to control the opening and closing action without having to push the seat 12 manually as is disclosed in the conventional device, thereby saving the user's 13 energy.

14 Further, the driver only needs to press the button of the emitter so as to control the opening and closing action without having to mount a lock as is 16 disclosed in the conventional device, thereby facilitating the operation of the 17 theftproof system.

18 Further, the seat motor and the seat movement control device hidden 19 under the seat can provide a locking effect so that they are not easily found or broken by the truder, thereby enhancing the theftproof function.

21 Further, as shown in Figs. 1 and 2, the slide track is secured to the 22 chassis of the car by bolts so that when the seat is moved forward, the bolts are 23 covered by the seat so that the seat cannot be dismantled at all, thereby further 24 enhancing the theftproof function.

It should be clear to those skilled in the art that further embodiments 26 may be made without departing from the scope of the present invention.
