Massaging system having isolated vibrators

Abstract

A vehicle massaging system includes a seat pad and motorized vibrators in respective regions of the pad; and a controller for selectively activating the transducers. Each of the vibrators is in a cavity of a main cushion member, the cavity being closed by an outer cushion member that supports an occupant, a soft or resilient isolation device being interposed between the vibrator and the main cushion member for reduced coupling of vibrations to structure or other portions of the seat, but enhanced coupling to a target region of the outer cushion member for improved selectivity of particular regions of a user's body to be massaged, and in multiple seating installations, unwanted vibration of one seat is suppressed during activation of vibrators in an adjacent seat. The transducer is bonded to the outer cushion member or a reinforcing sheet that is laminated thereto, the isolation device contacting a bottom portion of the transducer. Alternatively, the isolation device can completely enclose the transducer. The isolation device can include a flexible sealed enclosure containing a viscous material. An offset plate portion of a housing of the vibrator can extend between a structural member of the seat and the target zone region, a body portion of the vibrator being laterally spaced from the structural member when the structural member would otherwise block desired placement of the vibrator. The heater element can be fire resistant. Also disclosed is a method for converting a padded support to produce isolated massaging, and a method utilizing a subassembly of vibrators and the outer cushion member to facilitate production of the system.
