  • Patent number: 7214906
    Abstract: An apparatus for the independent control of the amount of heat produced by a right and a left side heated hand grip includes a control panel with various input buttons and a pair of LEDS that each indicates a relative power setting of one of the heated hand grips. A microprocessor receives input instructions from the input buttons and provides a first pulsed DC output having a desired duty cycle to one of the heated hand grips and a second pulsed DC output having either the same or a different duty cycle to a remaining one of the heated hand grips, thereby controlling the amount of heat produced by each respective heated hand grip. This improves comfort. Reverse polarity protection, a return to previous power settings, including a remembrance of a differential between the two heated hand grips, and automatic shutoff when battery voltage reaches a predetermined value are described.

  • Patent number: 7091450
    Abstract: A grip heater has a tubular insulator that is designed to slip over a handlebar and has two interposed pairs of helical recesses. Each pair of helical recesses is formed by two parallel helical grooves and accommodates a heating element; the heating elements can have different resistances to provide differing degrees of heat when selectively connected to a voltage source. Preferably, the pairs of recesses overlap such that the heating elements reside in alternating grooves and cross over each other. The heating elements can be connected to a common ground to allow replacement of existing three-wire grip heaters. When a common ground is employed, the heating elements are preferably isolated where they cross.

A shell has two or more shell parts that each extend at least part of the way around the periphery of the steering wheel rim in radial cross-section. The shell parts are joined together by an adhesive intentionally applied only to mutually contacting surfaces of said shell parts. The invention also relates to a method of manufacturing a heated steering wheel.

  • Patent number: 6268588
    Abstract: A steering wheel heating assembly 10 which electively provides a relatively high voltage electrical signal to a heating element 16 which is coupled to a steering wheel, effective to heat the steering wheel. The assembly 10 includes a temperature sensor 28 which senses or monitors the temperature of the steering wheel and which communicates the monitored sensor to a controller 26. Should the temperature of the steering wheel be above a certain value, the controller 26 prevents the relatively high voltage signal from being communicated to the heating element 16. The controller 26 may also monitor the operating speed of the engine and prevent such signal communication when the engine is not being operated.

  • Patent number: 6239409
    Abstract: The invention relates to a heating device for a moveable part of a motor vehicle such as an automobile which can be held, such as a steering wheel. The heater is connected to a source of electrical energy in a stationary part of the vehicle by a contact unit having a stator and a rotor. A voltage converter of the heating device is provided in the stationary part of the vehicle, before the contact unit or in the stator of the contact unit. The voltage converter enables the generation of a higher voltage than the normal 12 volt standard voltage of the vehicle.

  • Patent number: 6114668
    Abstract: A heater-installed grip for a vehicle includes substantially semi-cylindrical inner pieces (33.sub.1, 33.sub.2) of a synthetic resin which have a planar heater (34.sub.L, 34.sub.R ; 174.sub.L, 174.sub.R ; 184) wound around an outer periphery thereof and which are integrally embedded in a cylindrical grip body (35) made of a rubber assembled to a pipe-shaped steering handlebar (26) or a throttle pipe (79). In this heater-installed grip, a circumferentially central portion of each of the inner pieces (33.sub.1, 33.sub.2) is formed at a large wall thickness, as compared with circumferentially opposite ends thereof. Thus, the assemblability of the grip body (35) to the pipe-shaped steering handlebar (26) or the throttle pipe (79) is enhanced, while ensuring a die-clamping strength in a process for forming the grip body (35).

  • Patent number: 5847360
    Abstract: The electric steering-wheel heating element to be mounted on a steering wheel rim has a linear center region made of flat ribbon-shaped, electrically conductive material. A first side region and a second side region made of flat ribbon-shaped, electrically conductive material each have at least one curved side segment and. The shape of the center region and of the curved side segments is configured such that, after mounting, the center region covers an external circumferential region of the steering wheel rim, the first side region alongside a longitudinal side of the center region covers a side circumferential region on one side of the steering wheel rim and the second side region alongside the other longitudinal side of the center region covers a side circumferential region on the other side of the steering wheel rim.

  • Patent number: 5834734
    Abstract: A cylindrical rubber handgrip body to be connected to a handle bar pipe of, for example, a motor cycle, has a sheet-like heater embedded therein, and a power supply cord soldered to the heater and extending out of a side face of the grip body. The power supply cord extends inside the handgrip body along the circumference thereof over at least half a turn. A cord support of a high stiffness is provided in a cord exit portion of the handgrip body, for bearing the pulling force that acts on the power supply cord. Both the cord support and the handgrip body bear the pulling force that acts on the power supply cord and reduce the pulling force that is transmitted by the cord to the soldered connection to the heater.

  • Patent number: 5626780
    Abstract: A handgrip with a built-in heater for a motorcycle constituted by a hollow cylindrical handgrip body, wherein a flexible printed circuit heater is wound around an outer periphery of a synthetic resin inner piece of a substantially hollow cylindrical shape with a hollow cylindrical or peripheral portion slotted, and a cladding rubber layer is integrally molded thereon to cause the heater to extend between the inner piece and the cladding rubber layer. The heater is wound over a range covering a half circumference or more but less than a full circumference of the inner piece. The cladding rubber layer is molded in such a form that a region where the heater is not wound faces parting positions of mold halves for forming the cladding rubber layer so as to prevent the occurrence of turn-ups and creases.
