Abstract
An anti-theft device for a motor vehicle whereby the seat and seat back are mechanically and/or electronically moved and locked in the car forward position thus preventing a person from sitting in the driver's seat. The movement of the seat to this theft deterrent position and its reversion to a usable position may be arranged in many different ways.
Description
ANTI-THEFT SYSTEM FOR AUTOMOBILES
Background of the Invention The problem with many anti-theft mechanisms, however sophisticated, is that a potential theft can enter the vehicle and sit inconspicuously in the driver's seat, working to bypass or rernove the anti-theft device. However) if the driver's seat is moved forwardly to a position wherein it is adjacent to the steering wheel and locked in this position, a wood-be thief would have to attempt to move the seat to a usable position when either standing outside of the vehicle with the driver's door open, or when sitting in the passenger seat, and in either instance this would be likely to arouse suspicion. This anti-theft device can also work in tandem with other devices to improve their effectiveness. The fact that the seat i:; left in an un-usable condition is likely to provide a visual deterrent to a would-be thief, making it less probable that the vehicle would be broken into.
Brief Summary of the Invention In accordance with the invention, an anti-theft deterrent for an automotive vehicle which includes a steering wheel and a driver's seat mounted for fore and aft movement in relation to the steering wheel comprises means for locking the seat in a forward position. The locking means may be operable with a key, a keypad or by remote control, for example. The adjustment of the seat to its forward position may be manually controlled, or it may be automatically positioned upon activation of the deterrent.
Preferably, particularly where the movement of the seat is automated) an interlock will be provided so as to disable the seat movement when a load is detected on the seat.
The foregoing seats will normally comprise a squab portion and a back portion, typically, the back portion will be hinged to the squab portion in a manner to permit the rake of the sE~at-back to be adjusted. The forward movement of the seat to an anti-theft position may comprise a movement of the squab portion, or of the back portion, or preferably both, i.e. wherein the squab portion will move forwardly in a more-or-less linear manner, while the back portion undergoes a rotary movement.

Description of the Preferred Embodiments of the Invention Referring first to Figs. 1, 2 and 3, a seat for an automotive vehicle is identified generally therein by the numeral 10. Seat 10 comprises a squab portion 12 including a seat frame 14 and rails 16 which are fixed in relation to the automotive vehicle (not illustratE:d) within which the seat 10 is disposed, and along which the seat is movable to permit the position of the seat to be adjusted in relation to a steering wheel S of the vehicle. Seat 10 further includes a back portion 20 supported from frame 14 by means of a hinge 22 to permit the rake of the back portion to be adjusted. In Fig. 1, seat 110 is illustrated in a normal or driving position, relative to steering wheel S, while in Fig. 2 the seat is shown in a forwardly adjusted position in which it effectively blocks access to the steering wheel and precludes the seating of a person in the driver's seat of the vehicle.
In the first embodiment of thE~ invention, the position of seat 10 is adjusted manually, and several mechanisms for permitting such adjustment are known in the art, with that illustrated in Fig. 3 being a composite, schematic form; in accordance with the invention a latch handle 30 is provided which will latch seat 10 in its forwardly adjusted position, and a lock 32 is provided for locking latch handle 300 in position. It will be apparent that two separate handles such as handle 30 may be provided to permit the adjustment of the sq2uab portion 12 and the adjustment of the back portion 20 to be latched and locked separately. The operation of the invention of the first embodiment is summarized in Fic~. 8.
Referring now to Figs. 4 and 5, in a second embodiment of the invention, a seat 110 is movable on r;~ils 116 under the influence of a motor 118, while the rake of the back portion 120 is adjusted by motor 128. A
switch 130 actuated by a keyed lock 132 selectively connects motors 118, 128 to the battery B of the vehicle. The operation of the invention of this second embodiment is summarized in Fig. 9.
It will be appreciated that v~ithin the concept of the invention, electrically adjustable seats such as~ seat 10 may be controlled in many _3_ different manners with varying decrees of automation. In one semi-automated form exemplified in Figs. 6 and 7, it is assumed that the vehicle is equipped with a keyless remote entry system, including a switch 230. In this embodiment seat 210 is provided with a load sensor comprising a pad 240 including a normally closed switch 242 which opens when a load is placed on a seat squab portion 212 in the vicinity of pad 240. A normally open self latching switch 232 is provided which is settable to the ON position by an operator depressing switch control button 234 when it is desired to deploy the anti-theft system of the invention. Upon actuation of the remote system to lock the doors of the vehicle, switch 230 closes to provide power to seat adjustment motors 218, 228, causing 'the seat to move to its forward position.
In the event that a load is detected on pad 240, switch 242 will open to prevent the movement of seat 210. As seat 210 moves into its forward position, a seat position sensor switch 250 or a load sensor senses that the seat has moved fully to the theft detf~rrent position. Activation of the seat position sensor 250 opens switch 230 thus cutting all power to the seat.
activation of the keyless remote entry system will close switch 230 and allow the seat to return to its original position.
