A seat bottom 44 includes first 50 and second 60 thigh supports, each supported by and independently movable to adjustable positions relative to a frame 74. At least one inflator 132, 134, (130, figure 5) is in fluid communication with first 110 and second 112 deployable devices coupled to the respective thigh supports 50, 60. A controller (144, figure 7) is programmed to independently inflate the deployable devices 110, 112 based at least on adjustable positions of the thigh support 50, 60 in response to a sensed vehicle impact. Impact and/or pre-impact sensors may be in communication with the controller (144). The controller may inflate the deployable devices 110, 112 based on a sensed vehicle impact direction. The deployable devices 110, 112 (e.g. airbags) may be disposed between the thigh supports 50, 60 and at least one cushion 80. Cushion 80 may be moved into a comfortable position by independently rotatable thigh supports via first 54 and second 64 actuators. The thigh supports 50, 60 can be raised by unequal distances to the same height, reducing the likelihood of the occupant submarining below a seat belt lap portion during a front-end collision, and reducing forward travel of the occupant chest.
