Body support assembly and methods for the use and assembly thereof
A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.
1. A body support assembly comprising:
a base member;
a lower support structure comprising:
a longitudinally extending portion coupled to the base member at a first location; and
a front link extending forwardly and upwardly from the longitudinally extending portion forwardly of the first location, wherein the front link and the longitudinally extending portion are integrally formed;
a back member comprising a lower portion pivotally connected to the lower support structure at a fixed pivot axis, a rigid rear link integrally formed with the lower portion and pivotable with the lower portion about the fixed pivot axis, wherein the rigid rear link extends upwardly from the lower portion, and an upright portion extending upwardly from the lower portion; and
a seat having a front portion coupled to the front link and a rear portion coupled to the rigid rear link, wherein the seat comprises a rear edge spaced apart from a front surface of the upright portion of the back member.
2. The body support assembly of claim 1 wherein at least a portion of the upright portion comprises a pair of laterally spaced uprights defining a space therebetween.
3. The body support assembly of claim 2 wherein the upright portion comprises an upper cross member connected to upper ends of the uprights, and a bottom member connected to lower ends of the uprights, wherein the upper cross member, uprights and bottom member define an opening therebetween.
4. The body support assembly of claim 1 further comprising a body support member coupled to the upright portion and disposed in front of the upright portion, wherein the body support member comprises a textile material.
5. The body support assembly of claim 1 wherein a bottom portion of the seat, the front link, the longitudinally extending portion, and the rigid rear link define a laterally extending through-opening.
6. The body support assembly of claim 1 further comprising a tilt limiter engageable with the back member.
7. The body support assembly of claim 1 wherein the base member comprises a height adjustable support column, and further comprising an actuator operably connected to the height adjustable support column, wherein the actuator extends laterally outwardly from the base member.
8. A body support assembly comprising:
a base member;
a lower support structure comprising:
a longitudinally extending portion coupled to the base member at a first location; and
a front link extending forwardly and upwardly from the longitudinally extending portion forwardly of the first location, wherein the front link and the longitudinally extending portion are integrally formed;
a back member comprising a lower portion connected to the lower support structure and pivotable about a pivot axis, a rigid rear link integrally formed with the lower portion and pivotable with the lower portion about the pivot axis, wherein the rigid rear link extends upwardly from the lower portion, and an upright portion extending upwardly from the lower portion, wherein the lower portion, the rigid rear link, and the upright portion of the back member are integrally formed; and
a seat having a front portion coupled to the front link and a rear portion coupled to the rigid rear link, wherein the seat comprises a rear edge spaced apart from a front surface of the upright portion of the back member.
9. A body support assembly comprising:
a base member;
a lower support structure comprising:
a longitudinally extending portion coupled to the base member at a first location; and
a front link extending forwardly and upwardly from the longitudinally extending portion forwardly of the first location, wherein the front link and the longitudinally extending portion are integrally formed;
a back member comprising a lower portion connected to the lower support structure and pivotable about a pivot axis, a rigid rear link integrally formed with the lower portion and pivotable with the lower portion about the pivot axis, wherein the rigid rear link extends upwardly from the lower portion, and an upright portion extending upwardly from the lower portion; and
a seat having a front portion coupled to the front link and a rear portion coupled to the rigid rear link, wherein the seat comprises a rear edge spaced apart from a front surface of the upright portion of the back member, wherein the front link is bendable as the seat and back member are moved from an upright position to a reclined position.
10. The body support assembly of claim 1 wherein the back member comprises a transition portion disposed between the lower portion and the upright portion, wherein the transition portion is curved.
11. The body support assembly of claim 10 wherein an opening is formed at least in part in the transition portion and the upright portion.
12. The body support assembly of claim 1 wherein the seat comprises a peripheral frame defining an opening and a suspension member connected to the peripheral frame.
13. The body support assembly of claim 12 wherein the suspension member includes a textile material.
14. The body support assembly of claim 12 further comprising a cushion disposed on one side of the suspension member.
