A hybrid seat pan and diaphragm apparatus includes a seat pan that has a concave portion and a diaphragm positioned at an occupant-facing side of the seat pan and stretched across the seat pan at a first distance above the concave portion of the seat pan.
Claims14
A hybrid seat pan and diaphragm apparatus comprising:
- a seat pan that has a concave portion;
- and
- a diaphragm positioned at an occupant-facing side of the seat pan and stretched across the seat pan at a first distance above the concave portion of the seat pan;
- wherein the seat pan restricts deflection of the diaphragm under an occupant's weight by the diaphragm coming to rest on the seat pan such that an effective weight applied to the seat pan, by contact of the occupant with the seat pan via the diaphragm, is less than the occupant's weight.
1 more element
A seat apparatus comprising:
- a seat chassis that has side frames connected by a cross beam;
- a seat pan above the cross beam;
- and
- a tensioned diaphragm above the seat pan;
- wherein the seat pan is contoured to reduce contact pressure of an occupant's weight;
- and
- wherein the seat pan restricts deflection of the diaphragm under an occupant's weight by the diaphragm coming to rest on the seat pan such that an effective weight applied to the seat pan, by contact of the occupant with the seat pan via the diaphragm, is less than the occupant's weight.
4 more elements
A method for making a hybrid seat pan and diaphragm apparatus, comprising:
- stretching a diaphragm;
- and
- attaching the stretched diaphragm at an occupant-facing side of a seat pan and at a first distance above a concave portion of the seat pan;
- wherein the seat pan restricts deflection of the diaphragm under an occupant's weight by the diaphragm coming to rest on the seat pan such that an effective weight applied to the seat pan by contact of the occupant with the seat pan, via the diaphragm, is less than the occupant's weight.
