Abstract
A seat having a seat bottom assembly supporting a diaphragm between side members of a structural frame of the seat. The seat bottom assembly including a diaphragm having a first flank portion, a main portion and a second flank portion arranged between the side members, the main portion being between the flank portions. The diaphragm is supported such that the main portion of the diaphragm contains an effective length of stretchable material of the diaphragm when supporting an occupant of the seat.
Claims20
A seat comprising:
- a structural frame having a first side member and a second side member;
- and
- a seat bottom assembly connected to the first side member and the second side member;
- wherein the seat bottom assembly comprises a diaphragm having a first flank portion, a main portion and a second flank portion arranged between the first side member and the second side member, the main portion being located between the first flank portion and the second flank portion;
- wherein the diaphragm is supported such that the main portion of the diaphragm contains an effective length of stretchable material of the diaphragm when supporting an occupant of the seat;
- wherein the effective length of stretchable material of the diaphragm is limited to the main portion of the diaphragm;
- and
- wherein the diaphragm includes elastomeric filaments and wherein the elastomeric filaments of the diaphragm are continuous and uninterrupted through the first flank portion, the main portion and the second flank portion.
