Abstract

A system which automatically moves a drivers seat between one of a plurality of preselected driving positions and a position wherein ingress and egress is facilitated is inhibited when a passenger is seated on the seat behind the drivers one.

Claims

1. In vehicle

a front seat;

a rear seat;

means for detecting the presence of a passenger on said rear seat;

means for selectively moving the front seat forward and aft within said vehicle;

a switch, said switch being associated with the operation of said vehicle, said switch having a first state and a second state, said first state being automatically assumed when the vehicle is conditioned to be driven, and said second state being automatically assumed when said vehicle is conditioned so that a passenger can ingress or egress from said vehicle; and

a circuit including a memory, said memory being arranged to be conditioned to retain a first predetermined seat position and a first selectable seat position, said circuit being operatively connected with said seat moving means, said circuit being arranged to induce said seat moving means to automatically move said seat to said first predetermined position from the first selected seat position when said rear seat passenger detecting means indicates the absence of a passenger thereon and said switch assumes said second state.

2. A vehicle as claimed in claim 1 further comprising

a steering wheel;

means for selectively moving said steering wheel between a second predetermined position and a second selectable driving position,

said memory being further arranged to retain said second predetermined position and said second selectable position, and

said circuit being further operatively connected with said steering wheel moving means in a manner to move said steering wheel to said second predetermined position when said seat is moved to said first predetermined position and to moves to said steering wheel to said second selectable driving position when said seat is moved to said first selectable position.

3. A vehicle as claimed in claim 1 wherein said memory is arranged to memorize a plurality of first selectable seat positions, and is able to selectively induces a selected one of said plurality of first selectable seat positions upon demand.

4. A vehicle as claimed in claim 3 further comprising:

a device utilized during driving of said vehicle;

means for moving said device;

said memory being arranged to memorize a plurality of preferred device positions, each of said plurality of preferred positions corresponding to one of said plurality of selectable positions, said circuit being arranged to moVe said device to a preferred position which corresponds to the selected one of said selectable seat positions.

5. In a method of operating a vehicle having a front seat and a rear seat, the steps of:

memorizing a first predetermined front seat position wherein ingress and egress from said vehicle is facilitated;

memorizing a first desired front seat position suited to drive said vehicle;

moving said front seat to said first predetermined position in response to a first signal, said first signal being automatically produced in accordance with vehicle operation and indicative that the vehicle has assumed a condition wherein a passenger can either ingress or egress from said vehicle;

moving said front seat to said first desired position in response to a second signal, second signal being automatically produced in accordance with vehicle operation and indicative of the vehicle being conditioned to be driven;

sensing the presence of a passenger on said rear seat; and

inhibiting said front seat from moving from said first desired position to said first predetermined one in response to the first signal in the event that said step of sensing indicates the presence of a passenger on said rear seat.

6. A method as claimed in claim 5 further comprising the steps of:

memorizing a second predetermined position to which a steering wheel of said vehicle is moved to facilitate ingress and egress from said vehicle;

memorizing a second desired position to which the steering wheel is moved to facilitate driving of said vehicle;

moving said steering wheel to said second predetermined position in response to said first signal; and

moving said steering wheel to said second desired position in response to said second signal.

7. A method as claimed in claim 5 further comprising the steps of:

memorizing a plurality of first desired positions; and

selectively using one of said plurality of desired positions.

8. A method as claimed in claim 6 further comprising the steps of:

memorizing a plurality of second desired positions; and

selectively using one of said second desired positions.

9. In a vehicle having a front seat and a rear seat:

means for memorizing a first predetermined front seat position wherein ingress and egress from said vehicle is facilitated;

means for memorizing a first desired front seat position suited to drive said vehicle;

means for moving said front seat to said first predetermined position in response to a first signal, said first signal being automatically produced in accordance with vehicle operation and indicative that the vehicle has assumed a condition wherein ingress and egress from the vehicle is possible;

means for moving said seat to said first desired position in response to a second signal indicative of the vehicle being conditioned to be driven;

means for sensing the presence of a passenger on said rear seat; and

means for inhibiting said seat from moving from said first desired position to said first predetermined one in the event that said sensing means indicates the presence of a passenger on said rear seat.

10. A vehicle as claimed in claim 9 further comprising:

means for memorizing a second predetermined position to which a steering wheel of said vehicle is moved to facilitate ingress and egress from said vehicle;

means for memorizing a second desired position to which the steering wheel is moved to facilitate driving of said vehicle;

means for moving said steering wheel to said second predetermined position in response to said first signal; and

means for moving said steering wheel to said second desired position in response to said second signal.

11. A vehicle as claimed in claim 9 further comprising:

means for memorizing a plurality of first desired positions; and

means for selectively using one of said plurality of desired positions.

12. A method as claimed in claim 9 further the steps of:

means for memorizing a plurality of second desired positions; and

means for selectively using one of said second desired positions.
