Abstract

A vehicle seat has several adjustment devices, e.g. for the seat back, for the angle of the seat base, for horizontal positional adjustment etc., which are operated by an electric motor. With the object of reducing the cost and installation expense of such electro- mechanically adjustable vehicle seats a single electric motor 30 is used for two or more adjustable devices 23, 24, 25, 26, with the output shaft 31 of the electric motor being able to be connected through couplings heads 32 and flexible connections 33 to any one of the input shafts 27 of the adjusting devices, as desired. Various design solutions are proposed for use with such a single motor drive. <IMAGE>

Description

SPECIFICATION Seat with multiple adjustments operable by an electric motor The invention concerns a vehicle seat with at least two adjustment devices, such as for example a seat-back adjuster, seat-base angle adjuster, horizontal positional adjuster etc., each of which possesses a rotatable input shaft which is driven by means of an electric motor connected to the input shaft.
Vehicle seats which may be adjusted by means of electric motors are notable for an ease of operation which increases driving safety. Only a few vehicle seats with electromechanically operated adjusters are currently in use, however, since the cost of the electromechanical drives for the various adjusters are very high and since the installation of the various electric motors in the vehicle seat causes considerable expense.
The object of the invention is to reduce the cost and installation expense of electro-mechanically adjustable vehicle seats.
According to the invention a vehicle seat has at least two adjustment devices each of which includes a rotatable input shaft, wherein an output shaft of an electric motor is arranged to be selectively coupled to any one of the input shafts of the adjustment devices.
Thus one electric motor may be used for two or several adjustment devices or even for all the adjustment devices in a vehicle seat. By using a single-motor drive for all the adjustment devices in vehicle seats, considerable reduction in the cost of such seats is achieved at the same time reducing installation expenses by installing a single motor during manufacture of the vehicle seat. The singlemotor drive is arranged so that it can only be coupled with one selected adjustment device at any one time and this ensures that the single motor does not need to have a higher rating than has previously been required for each of the various electric motors used for powering the various adjustment devices.
When applying the solution proposed by the invention in practical design, it is possible for the electric motor to be mounted in a fixed position on the frame of the vehicle seat and for coupling heads for the adjustment devices to be mounted so that they can be moved as selected and made to engage with a corresponding coupling head on the output shaft of the electric motor. But since the individual adjusters are positioned at different points in the vehicle seat, a shaft connection from each coupling head to its associated adjustment device is required.This makes it difficult to mount the coupling heads so that they can move so preferably the electric motor is mounted on the seat frame in such a way that it is movable by sliding or pivoting into selected positions at each of which its output shaft is in driving engagement with a coupling head located in a fixed position, the coupling head being drivingly connected by means of a shaft to an input shaft of an associated adjustment device.
But moving of the electric motor relative to the seat frame can lead to manufacturing expenses, and this is avoided in an alternative arrangement in which the electric motor is mounted in a fixed position on the seat frame and coupling heads are fitted in fixed positions at equal-distances from the output shaft of the motor, the coupling heads each being connectable by means of a shaft connection to the input shaft of an associated adjustment device, the output shaft of the motor being selectively coupled to any one of the coupling heads.
In this arrangement conveniently the output shaft of the motor carries a driving pinion which is positioned centrally relative to the coupling heads which each include a toothed wheel, an intermediate toothed wheel being in mesh with the driving pinion and engageable with any one of the coupling toothed wheels by means of a lever pivotable around the axis of the driving pinion. Alternatively friction wheels can be used instead of toothed wheels but toothed wheels are preferred because it is possible to produce via the intermediate wheel or via several intermediate wheels reduction gearing with the result that the electric motor may have a lower power output.
Conveniently the lever is lockable in selected positions in which the intermediate toothed wheel engages with a toothed wheel of a coupling head by means of a locating lever, the locating lever opens an electrical contact which interrupts the power supply to the electric motor when the locating lever is in an unlocked condition. This ensures that the electric motor can only be operated when the intermediate toothed wheel is in a meshing position, so that the engagement and disengagement of the drive when changing the electric motor from one adjustment device to another adjustment device only occurs when the motor is stopped, thus avoiding the expense of synchronisation of the various drives.
Additional electrical contacts are provided for operating the electric motor, by means of which the electric motor rotates clockwise or anti-clockwise as desired.
In another arrangement the output shaft of the motor carries a drive pinion which is positioned centrally relative to coupling shafts whose axes lie parallel to the motor output shaft, each of the coupling shafts being connected with the input shaft of an associated adjustment device, each coupling shaft carrying a toothed wheel slidable in its axial direction, and the toothed wheels each being engageable with the driving pinion by means of a slider.
Each slider may be movable axially of the axis of the connecting shaft by means of a lever which may be turned in either direction, the lever operating electrical contacts in its end positions which cause the electric motor to rotate either clockwise or anti-clockwise.
This enables the transfer of the electric motor drive from one adjustment device to another to be carried out with the motor stopped.
Only with the lever at its terminal positions, which is when the axially-movable coupling toothed wheel is already completely engaged with the driving pinion of the motor, can the electric motor be run.
Preferably the shaft connections between each of the coupling heads and its associated adjustment device are in the form of flexible shafts, since these simplify installation between on the one hand the adjustment devices which are positioned at various positions on the vehicle seat and on the other hand the coupling heads which are positioned close together at different positions on the vehicle seat. Such shaft connections can, of course, also be provided by jointed drive shafts (Cardan shafts), by flat or V-belts or other shaft connections as appropriate.
Conveniently the electric motor is mounted in an opening at one side of the seat and the coupling means is mounted in an opening on the opposite side of the vehicle seat, and the openings in the sides of the seat are arranged so that the electric motor and the coupling means may be mounted on either side of the vehicle seat. The output shaft of the electric motor would in this case be correspondingly longer.
This arrangement has advantages, particularly in the case of vehicle seats with a moulded plastic seat base. If the moulded seat base possesses openings on the opposite external sides of the vehicle seat, then there is no difficulty in converting the seat from righthanded operation to left-handed operation by interchanging the electric motor and the coupling heads.
In the following, embodiments of the invention are described in more detail with reference to the drawings, in which: Fig. 1 is a perspective and schematic view of one embodiment of vehicle seat, Figs. 2 and 3 show a side view and a plan view respectively of another embodiment of vehicle seat, Figs. 4, 5 and 6 are external side elevations and a plan view of a further coupling arrangement, Figs. 7, 8 and 9 are cross-sections of the arrangement of Figs. 4-6 showing the internal coupling construction, Figs. 10 and 11 are views of the coupling arrangement of Figs. 4-9 showing an electrical connection arrangement, and Fig. 1 2 is a perspective schematic view of a further embodiment of vehicle seat.
Referring to the drawings and firstly to Fig.
1 a vehicle seat is shown which has a seatback 20 and an upholstered seat-base 21 together with a seat frame 22. Within the seat at various points are adjusting devices, e.g. an adjuster 23 for adjusting the seat angle at the rear, an adjuster 24 for adjusting the seat angle at the front, an adjuster 25 for adjusting the angle of the seat-back, and an adjuster 26 for changing the horizontal position of the seat upon a sliding seat guide (not shown) All these adjusters are of known kind and further adjusters may be added. The adjusters each include a rotatable input shaft 27 and in most cases a spindle 28 which is driven by the input shaft and upon which is positioned a travelling nut (not shown) which changes its position under rotation of the adjusting spindle 28 and consequently effects the adjustment required.In the adjuster 26 shown in Fig. 1 a driving pinion 29 is operated by the input shaft and the seat can be adjusted horizontally by this means on a sliding seat guide (not shown) These adjusting devices can be replaced by other arrangements to those shown.
The adjusting devices are all driven by a single electric motor 30, the output shaft 31 of which may be selectively coupled with any one of several coupling heads 32, as desired.
The coupling heads 32 are each connected by flexible shaft connections 33 with the input shafts 27 of the various adjusting devices 2326.
As shown in Fig. 1, to provide for the coupling of the output shaft 31 of the electric motor 30 with any one of the coupling heads 32, the electric motor 30 is mounted so that it can be moved in a slide guide 34 which is attached to the seat frame 22 by some appropriate means. This makes it possible to slide the electric motor 30 by hand aiong its guide 34 from one position to another where the output shaft 31 is in each case coupled with one of the coupling heads 32. Control of the electric motor to run clockwise or anticlockwise is carried out in the normal manner electrically and it is also possible to provide for the movement of the electric motor 30 in its guide 34 to be carried out by means of a separate handle, it being possible to locate or fix the electric motor in one of the desired positions.
Figs. 2 and 3 show a coupling system but with familiar parts of the vehicle seat omitted.
The coupling system may, for example, be mounted at the side on the seat frame, as can be seen from parts 30, 31, 32, 34 in Fig. 1.
A bearer plate 35 is rigidly attached to the seat frame (not shown) and carries an electric motor with an output shaft 37, driving pinion 38 and four coupling heads in the form of toothed wheels 39, which in each case are connected with the adjusting devices by means of flexible shafts 40, in the manner shown in Fig. 1.
Firmly attached to the bearer plate 35 via a bottom plate 41 is a front plate 42 which carries a bearing journal 43 which is positioned coaxially with the output shaft 37 of the electric motor. Pivotally mounted on the journal 43 is a hand lever 44 which can be locked at various angles by means of a locating lever 45 which for this purpose engages with notches 46 in the front plate 42. The locating lever 45 is pivoted on a bolt 47 and is operated by means of a thumb-pressure lever 48 which when pressed pivots around a bolt 49 and transmits its motion to the locating lever 45 via a connecting rod 50.
Thus in order to operate the coupling system the hand lever 44 may be grasped by the user of the vehicle seat and may be unlocked by means of the lever 48 by thumb pressure, whereupon the hand lever 44 may be moved to various positions set by the notches 46. In each position the driving pinion 38 of the electric motor is always in engagement with one of the coupling toothed wheels 39 via an intermediate wheel 51 which is mounted in a bearing in the hand lever.
Since the engagement positions can be set with the hand lever 44 only when the locating lever 45 is unlocked, and since the locating lever 45 actuates an electrical contact 52 immediately when unlocked, this causes the power supply to the electric motor to be interrupted by the electrical contact 42 whenever a different engagement position is to be selected for the intermediate wheel 51. The hand lever 44 also possesses an electrical rocker switch 53 by means of which the electric motor can be controlled to run either clockwise or anti-clockwise dependent upon the position of the rocker switch, but only when the locating lever 45 is in its locking position where the contact 52 is not actuated.
Referring to Figs. 4-11, in this embodiment the coupling system has a driving pinion 60 which is positioned centrally relative to four coupling shafts 61 with coupling toothed wheels 62 fitted on the shafts 61 in such a way that they are able to slide in an axial direction, whilst the central driving pinion 60 is fixed on a drive shaft 63. Fig. 6 shows an underneath view of the coupling system with the drive shaft 63 and the four coupling shafts 61. The drive shaft 63 is connected to the electric motor either directly or via an intermediate shaft and the coupling shafts 61 are connected with the input shafts of their associated adjusting devices by means of shaft connections.
Each coupling toothed wheel 62 may be moved axially upon its coupling shaft 61 from a rest position (Fig. 8) into an operational position (Fig. 9) by means of an associated lever 64. For this purpose each lever 64 possesses a thrust segment 65 with two thrust curves 66 which move a slider 67 on its shaft 68 axially against the force of a return spring 69 whenever the lever 64 is turned in one direction or the other. Fig. 8 shows the slider 67 in its rest position and Fig. 9 shows the slider 67 in its operational position.
Attached to each slider 67 is a guide claw 70 which guides the coupling toothed wheel 62 concerned and together with the slider moves it axially on the coupling shaft.
In its forward operational position as shown in Fig. 9, the coupling toothed wheel 62 is in engagement with the central driving pinion 60 so that the electric motor drives the relevant vehicle seat adjuster via the drive shaft 63, the central driving pinion 60, the relevant coupling toothed wheel 62 and the relevant coupling shaft 61.
As previously stated, as a result of the double and inversely inclined thrust curves 66, the slider 67 is always moved into its operating position as shown in Fig. 9 regardless of whether the lever 64 is turned around its axis of rotation to the right or to the left.
This turning movement of the lever 64 is however used at the same time to start the electric motor and to cause it to run either clockwise or anti-clockwise dependent upon whether the lever 64 is turned either to the right or to the left. The components required to control the electric motor are shown in Figs. 10 and 11, and these components are shown alone in Figs. 10 and 11 only for reasons of clarity. They are normally housed together with the components shown in Figs.
7 to 9 in one and the same changeoever unit, the external view of which is shown in Figs. 4 to 6.
As can be seen in Fig. 10, each thrust segment 65 of the four levers 64 possesses two lugs 71 and 72, each of which interacts with one connecting strip 73 or 74 and slides these, as can be seen in Fig. 11, either to the left or to the right so as to actuate an electrical contact 75 or 76. The electric motor runs clockwise, or anti-clockwise by means of the electrical contacts 75 or 76. Normally only one lever 64 in the illustrated coupling system will be operated at a time by a user of the vehicle seat, since he will only have one hand available at the side where the coupling system is mounted, but it would be theoretically possible for the user of the seat to attempt to operate for example the two levers shown at the top of Fig. 10 at the same time, but in opposite directions. This would cause the electric motor to be switched to clockwise and anti-clockwise at the same time.To prevent this occurring the two connecting strips 73 and 74 are interconnected by means of a peg 77 which engages with a slot in the lower connecting strip 74 (Fig. 11) and which only permits the movement necessary for one shift of a connecting strip.
Fig. 1 2 is an oblique perpsective view of a vehicle seat, seen from below with two open ings 78 on opposite external sides of the seat.
The dimensions of the two openings are the same and are so selected that a coupling system 79 with handles or levers 80 can be fitted into one of the openings 78 and that an electric motor 81 is mounted into the other opposite opening 78, the motor being connected by an intermediate shaft 82 with the coupling system 79 which may take the form described in more detail in relation to Figs. 411.
The dimensions of the openings 78 on opposite external sides of the vehicle seat as shown in Fig. 1 2 are selected so that the electric motor 81 and the coupling system 79 with the handles or levers 80 may also be installed in the reverse manner in the openings 78 in the vehicle seat, so that the vehicle seat as shown in Fig. 1 2 can very easily be converted from right hand operation to left hand operation.
