Vehicle occupant support
View Patent ↗An arrangement in passenger vehicles, that provide a mechanism for reducing the peak inertial loading on the occupant including children during lateral acceleration, and has synergistic comfort, convenience and utility features.
1. An occupant support in a vehicle comprising a base with an upward facing surface, and a mechanism supported by said upward facing surface, for reorientation of the occupant in response to a lateral inertial loading, wherein said mechanism comprises slides with a shell slidably mounted thereon, wherein said shell is adapted to translate along said slides and pivot with respect to said slides in response to the lateral inertial loading, said mechanism further comprising a primary anatomical cushion and a secondary chamber, wherein the primary anatomical cushion and the secondary chamber are both filled with a viscous fluid and interconnected, thereby enabling measured volumes of the viscous fluid to vent from the primary anatomical cushion to the secondary chamber, such that under gentle pressure the viscous fluid vents from the primary anatomical cushion to the secondary chamber enabling the anatomical cushion to conform to an anatomical element of the occupant, but under said lateral inertial loading and resulting compression the primary anatomical cushion provides high levels of resistance to motion of the occupant.
2. An occupant support as in claim 1 , wherein said viscous fluid filled anatomical cushion is adapted to support the occupant's head.
3. An occupant support as in claim 1 , wherein said viscous fluid filled anatomical cushion is adapted to support the occupant's thorax.
4. An occupant support as in claim 2 , further comprising a headrest with a pair of pillow pads for support of the occupant's head enabled to articulate from an angled position to provide support for the occupant in a sleeping position and to a near vertical position to provide lateral support as the shell reorients during said lateral inertial loading.
5. An occupant support as in claim 2 , further comprising a headrest with a pair of pillow pads for support of the occupant's head, further comprising a harness, wherein said pillow pads are enabled to articulate towards the occupant's head to reduce a gap between pillow pads when said harness provides support for a torso of the occupant under inertial loading in a forward direction.
