Claim Text:
1. A haptic feedback system, comprising: a bottom seat member comprising a seat pan with a first side and a second side, a first bolster positioned on the first side of the seat pan, and a second bolster positioned on the second side of the seat pan, wherein the first bolster and the second bolster include a resilient material; a first motor supported by the resilient material of the first bolster; a second motor supported by the resilient material of the second bolster, wherein the first bolster defines a first depression in a first upper surface and the second bolster defines a second depression in a second upper surface, and wherein the first motor is disposed within the first depression and the second motor is disposed within the second depression; and a seat frame, wherein the resilient material of the first bolster is disposed between the first motor and the seat frame to attenuate vibrations between the first motor and the seat frame, and wherein the resilient material of the second bolster is disposed between the second motor and the seat frame to attenuate vibrations between the second motor and the seat frame; and a controller in communication with the first motor and that generates a pulse width modulation (PWM) signal to command the first motor and the second motor, wherein the controller generates the PWM signal that commands the first motor to generate haptic pulses so that a first peak vertical acceleration at the first upper surface of the first bolster in a vertical direction is at least five times greater than a second peak acceleration in a fore-aft direction and a third peak acceleration in a lateral direction.
