Chair having a dynamically-flexible back and seat

摘要

A chair including a dynamically-flexible back and seat having a shape that adjusts to the movements of a user seated in the chair to enhance user comfort. Each of the back and seat has an air gap formed therewithin and a resilient frame or liner with a spring memory. The resilient liner is adapted to flex in response to compressive forces that are generated as the user slides his body back or from side-to-side in the chair. Accordingly, some of the chair back and some of the chair seat move into respective air gaps so that the shapes of the back and seat change to conform to the movements of the user. The air gaps also establish air flow ventilation channels which run laterally through the back and seat of the chair.

主权项

1. A chair comprising a back and a seat, said back including a firm back support, an opposing flexible back rest spaced from said firm back support such that a first air space is created therebetween, first resilient means comprising a flexible liner carried by said flexible back rest in opposite facing alignment with said firm back support and having a top, a bottom and a spring memory, a first pair of ties being spaced from one another and extending from the top of said flexible liner through said firm back support for attaching said top to said firm back support, and a second pair of ties being spaced from one another and extending from the bottom of said flexible liner through said firm back support for attaching said bottom to said firm back support, said flexible liner bending between said first and second pairs of ties and moving with said flexible back rest towards said firm back support and into said first air space to cause the shape of said chair back to change in response to compressive forces generated by a user's movements in the chair pushing back and sliding side-to-side against the flexible back rest, and said flexible liner expanding between said first and second pairs of ties and moving with said flexible back rest out of said first air space and away from said firm back support after the compressive forces generated by the user's movements are terminated, whereby the chair back returns to its original shape prior to said first resilient means bending.
