BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention concerns a system for adjusting the position of at least two elements of an automobile vehicle.
It applies in particular to adjusting the position of a seat cushion and a seat squab of an automobile vehicle.
Electrical means are more and more frequently used to adjust the position of the various elements constituting an automobile vehicle seat, in particular to adjust the position of the seat cushion and the seat squab.
The increase in the number of electrical adjustment means leads to an increase in the number of control switches. These switches are very often disposed at locations that the user cannot see when driving the vehicle.
What is more, the control switches are not always laid out in a logical manner evident to the user.
DE-A-36 08 818 describes a system for adjusting the position of at least two elements of an automobile vehicle of the kind in which each element is mobile in accordance with at least one elementary movement in two opposite directions at will, the adjustment system including a common control device for all the elements to be adjusted including means for adjusting the position of the elements, these adjustment means including, on the one hand, means for selecting an element to be adjusted and an elementary movement of that element and, on the other hand, means for executing the selected movement in a given direction, the adjustment system further including means for displaying information indicating the element and the elementary movement selected.
SUMMARY OF THE INVENTION
One aim of the invention is to propose means for adjusting the position of the seat cushion and the seat squab of a seat that do not have the above drawbacks and that can be controlled easily by a driver of the vehicle.
To this end, the invention consists in a system for adjusting the position of at least two elements of an automobile vehicle, of the aforementioned type, characterized in that it includes means for allocating the control device either to adjusting the position of the movable elements or to controlling at least one other non-movable element, such as a car radio.
In accordance with other features of the invention: means and the control device includes a control system including electric switches and a microprocessor unit to which the control system and the electromechanical drive means are connected, microprocessor unit, integrated into the steering wheel so that the switches can be operated by the fingers of a driver whose hands remain on the steering wheel, an elementary movement and the means for executing the elementary movement include two electric switches each controlling one direction of execution of the elementary movement, the switches for selecting the element and the direction of movement being integrated into the control system, execution of the various element position adjustments, positions forming the means imposing a logical sequence, movement of this selector switch in the same direction successively selecting the various elements to be adjusted and their elementary movements, means for imposing a logical sequence, simultaneous actuation of these two switches selecting successively the various elements to be adjusted and their elementary movements, elementary movement and the position of the selected element, element and means for selecting a stored position, memory and an electric switch for storing a position of the element in that memory, the memory recall and stored position activation switches being integrated into the control system, selective recall of a memory and an electric switch for activating the stored position, the memory recall and the stored position activation switches being integrated into the control system, adjustment means, the position storage means and the stored position selection means and the control device includes means for selective activation of the element position adjustment means, the position storage means and the stored position selection means, the control system, in a standard position inclu
