Kinematic seat with elastic pivot

摘要

Embodiments of the present invention provide an improved pivot articulation for a kinematic seat. Certain embodiments provide an elastic pivot that is formed as flexion weaves that connect upper and lower portions of a seat back. The flexion weaves may be inner and outer legs that are curved in configuration or that have bent dimensions.

主权项

1. A kinematic seat, comprising:
(a) a lower seat frame, (b) a seat pan, (c) a seat backrest that pivots with respect to the lower seat frame, and (d) left and right side beam supports supporting left and right elastic pivots positioned above the seat pan, each of the left and right elastic pivots extending from an end of the side beam support and comprising a first flexion weave and a second flexion weave, wherein the first flexion weave and the second flexion weave are arranged in an x-configuration such that they cross one another, wherein the first flexion weave and the second flexion weave are secured to and connect with the seat backrest, such that the seat backrest rotates and reclines with respect to the seat frame by pivoting at the elastic pivots, wherein each of the first and second flexion weaves curve slightly once tension is applied to allow movement of the seat backrest with respect to the seat frame.
