Definitions

  • This invention relates to a warming pad intended for use on the back of a vehicle seat.
  • a warming pad adapted to be positioned between the vehicle seat and a user which is supplied with heating electrical current from the electrical power supply of the vehicle.
  • the problem to which this invention is directed is the difficulty that, where such a device is to be an accessory for a motor vehicle, it will need to be connected to a power supply within the vehicle which can supply a significant level of electrical current and which can be easily accessed by an intending user.
  • a connection is the electrical cigarette lighter socket which is conventionally available in every vehicle.
  • a vehicle seat heating pad including an electrical connector adapted to be connected to a power supply of a motor vehicle and including distributed electrical conductors within the pad to provide a source of heat when electrical current flows there through, and switch means to effect a selection of some of said electrical conductors for electrical connection to said power supply.
  • a heating pad to be located lying against a support surface of the back of a vehicle seat where the pad includes an electrical connector to be inserted into the cigarette lighter socket of a motor vehicle to gain access to a power supply thereby, the pad including distributed electrical conductors within the pad to provide a source of heat when electrical current flows there through, and switch means to effect a selection of said electrical conductors whereby there is provided a first extent of heating from a first switch position and in respect of a second switch position, a different degree of heating from the first.
  • a switch with the pad, which is positioned so that the electrical resistance wires will only be connected electrically to the plug and therefore as appropriate any source of power when there is an applicable pressure on the pad in the vicinity of the switch to effect the switching of this under such pressure.
  • switch means to allow for switching between the two relative positions.
  • a switch and lights are incorporated into a plug which can be fed into the cigarette lighter socket, then there can be provided at least two lights which can be independently indicative of a high or low heat setting in connection with the pad.
  • Figure 1 is a perspective view of the embodiment as it could be expected to be used in a motor vehicle, with a plug in a position to be located within an appropriate socket within the motor vehicle,
  • Figure 2 is an enlargement of the plug about to be positioned within the cigarette lighter socket, the plug including a switch and two lights which would indicate the selected position being either for high heating or low heating,
  • Figure 3 is a side view of the plug showing some instructional elements
  • Figure 4 is the same side view as in Figure 3 showing however further electrical connections with mechanical parts being not shown,
  • Figure 5 is an illustration of one pattern of resistance wiring within the pad showing the electrical connections to provide for two heat settings
  • Figure 6 is an exploded view of a further embodiment.
  • the pad 1 is intended to be positioned on the front surface of the back of vehicle seat such as at 2 and the embodiment shows the pad 3 supported by tapes 4 which are tied around stalks supporting the headrest 5.
  • Each pad has a front layer and a back layer both of which are chosen to be of a material which is self supporting fibrous material which is selected to provide a relatively stiff support for electrical resistance wiring but also will provide a pressure averaging effect so that any pressure switch will be activatable by pressure derived from a broader area of pressure against the pad 1 and also protect the resistance wiring from having to conform with sharp bends where for instance the pad is pressed back into the shape of the front face of a vehicle seat.
  • This stiffer material also has the effect of protecting the warming resistance elements from being excessively bent to conform for instance to the shape of a back of a car seat.
  • the degree of stiffness of each pad is such that they will generally maintain a broad rather than a narrow curvature under normal usage. This will then assist in maintaining a longer life for the resistance wires and reduce any risk of bending stress fracturing of these in the very demanding location of the back of a vehicle seat.
  • a pattern of resistance wiring arranged as specifically shown in Figure 5 so as to provide relatively uniform heating across the pad and connected so that there are two separate wiring situations so that for a given voltage, in a first position, there will be a lower heating condition as compared to a second connection.
  • the arrangement shown is appropriate for a 24 volt supply but a different arrangement can be used for a 12 volt supply).
  • a pressure switch 6 which is positioned at a lower end of the pad 1 so as to provide an electrical contact only in the event that pressure is being applied to the switch and thus allow heating only in the event that a person is actually sitting in the seat.
  • the switch 6 cannot be operated in other ways but of course its purpose is to provide a reasonably automatic safety factor both from undue discharge of a battery and also safety from obtaining an overheating effect in the event that the high setting is left for too long in wrong conditions.
  • An electrical cord 7 connects the pad 3 to a plug 8.
  • the plug 8 includes a traditional electrically connecting male end at 9 which is adapted to fit within a cigarette lighter socket 10.
  • a switch 11 has three positions a middle one of which is in an off position so that there is no electrical circuit made to the pad 3, and in a first position which is to say forward in figure 2, this will be such that a first selected extent of resistance wires in the pad will be connected to the voltage supply of the vehicle and further, the switching also interconnects the voltage supply to a light emitting diode of a selected colour (for low heat setting green is appropriate and for the high heat setting red is considered appropriate) at 12.
  • One feature is that the illumination of the light emitting diodes 12 or 13 are affected by contacts through the switch so that they are illuminated appropriately when the switch position is in the appropriate position and are not illuminated simply by the passage of current through the switch to the electrical resistance wiring.
  • the circuit in Figure 4 includes three electrical wires at 14, 15 and 16 where 14 is connected only through the switch 6. This then provides for alternate connections to the separate circuits shown in the one case as the thinner lines at 17 and in the other case as the thicker lines at 18.
  • outer pads 20 and 21 which are selected from a long lasting fibrous matting material which are cut so that they are left to join at 22 and therefore will fold up together and can be kept in that position either by stitching or by appropriate application of a gluey material.
  • the heating element 23 which is held between two linen sheets 24 and 25 which capture between them the electrical resistant element material 23 and these are held together by appropriate silicon based sealant which also acts as a glue.
  • the tape 20 at 30 is captured and further held permanently in position.
