Abstract
A body support structure includes a frame and a membrane attached to the frame. The membrane includes elastomeric filaments. The membrane includes different regions with different stiffness. The membrane may form a part of a seat or a backrest.
Claims21
A body support structure comprising:
- a frame defining a backrest, the backrest having an upper section and a lower section;
- and
- a membrane attached to the frame and comprising intertwined filaments, the membrane having a first region with a first stiffness, a second region with a second stiffness, and a third region with a third stiffness,
- wherein the second stiffness is greater than the first stiffness and the third stiffness is greater than the first stiffness and the second stiffness, and
- wherein the first region is positioned in the lower section of the backrest and at least a portion of the first region is configured to support the lower back of a user, the third region is positioned above the first region and at least a portion of the third region is configured to support the spine of a user, and the second region is positioned above the first region.

A body support structure comprising:
- a frame defining a seat, the seat having a front section and a rear section;
- and
- a membrane attached to the frame and comprising intertwined filaments, the membrane having a first region with a first stiffness, a second region with a second stiffness, and a third region with a third stiffness,
- wherein the second stiffness is greater than the first stiffness and the third stiffness is greater than the first stiffness and the second stiffness, and
- wherein the third region is positioned in the front section of the seat, the second region is positioned behind and adjacent to the third region, and the first region is positioned behind and adjacent to the second region.

A body support structure comprising:
- a frame;
- and
- a membrane attached to the frame and comprising filaments, the membrane formed from a woven material having a first region with a first stiffness, a second region with a second stiffness, and a third region with a third stiffness,
- wherein the second stiffness is greater than the first stiffness and the third stiffness is greater than the first stiffness and the second stiffness, and
- wherein the first stiffness, second stiffness, and third stiffness are formed by variations in the membrane weave or material prior to attaching the membrane to the frame.
