Abstract
A seat bladder weight estimation apparatus includes an interface panel having multiple regions of substantial rigidity separated by regions of insubstantial rigidity. The regions of substantial rigidity limit sensitivity to seat foam variations, and the regions of insubstantial rigidity permit differential movement and angulation of the rigid regions for regional transfer of occupant weight to the bladder. The regional transfer of occupant weight to the bladder allows regional variation of the bladder sensitivity to occupant weight through various bladder geometry design features.
Claims8
Occupant weight estimation apparatus for a vehicle seat comprising:
- a fluid-filled elastomeric bladder disposed in said seat;
- and
- an interface panel of non-uniform rigidity disposed adjacent to said elastomeric bladder for transferring occupant weight to said bladder, said interface panel having multiple rigid regions joined by intervening flexible regions, where said intervening flexible regions deflect in response to occupant weight to permit differential movement and angulation of said rigid regions to achieve regional transfer of said occupant weight to said bladder.
