Modular ergonomic chair

Modular ergonomic chair description/claims

This application is a Continuation of U.S. application Ser. No. 11/210,350, filed on Aug. 23, 2005, which is hereby incorporated by reference in its entirety.

This invention relates to the field of chairs and other seated, support apparatus.

Chairs may be found in nearly every home or office environment where they serve important functions in increasing productivity, relieving stress, decorative aesthetics, and so forth. However, most chairs cannot provide many of these features simultaneously and are purpose-built to favor one function or purpose at the expense of others.

There is thus a need for a chair that can effectively deliver form, function, and adaptability.

In order to meet the need for a versatile chair for use in home, office, and other settings, the present application provides a modular chair that can be easily adapted for a wide range of functions while comfortably and ergonomically supporting a diverse range of users and body types.

In one embodiment, the application provides an ergonomic chair with (a) a chair base; (b) a support column coupled to the chair base; (c) a seat base having a seat base pivot, with the seat base coupled to the support column; (d) a seat having at least one mount, the seat being coupled to the seat base pivot; and (e) one or more knee support pads that are coupled to a knee support pivot, with the knee support pivot coupled to one or more of the chair base, the support column, the seat base, and the seat.

In another embodiment, the seat has more than one mount. Preferably, the seat may have a mount in the front and one situated on the back, relative to the facing of a typical user. In an embodiment, such mounts may find use as coupling points for further attachments.

In yet another embodiment, the chair has more than one knee support pad. Preferably, the chair has two knee support pads. In an embodiment having more than one knee support pad, the knee support pads pivot independently on the knee support pivot, to which they are attached.

In an embodiment of the chair, a modular support member, capable of supporting one or more removable attachments, is coupled to a seat mount. Preferably, the coupling between modular support member and the seat mount is non-permanent and made using a locking pin mechanism.

In one embodiment employing a support member, the knee support pivot is coupled to the modular support member. Preferably, the coupling between the knee support pivot and the support member is non-permanent and may be made at a variable position on the support member. Even more preferably, the coupling between the knee support pivot and the support member is made using a securing means, such as a locking pin mechanism, or equivalent coupling means. In another embodiment employing a support member, a thoracic support pad is coupled to the modular support member. Preferably the thoracic support pad is a chest support pad. Preferably, the coupling between the thoracic support pad and the modular support member is non-permanent and made at a variable position on the support member. More preferably, the coupling between the thoracic support pad and the support member is made using a locking pin mechanism.

In yet another embodiment of the chair employing a modular support member, a head support is coupled to the modular support member. Preferably, the coupling between the head support and the modular support member is non-permanent and made at a variable position on the support member. More preferably, the coupling is made using a locking pin mechanism.

In an additional embodiment employing a modular support member, a work surface is coupled to the support member. Preferably, the coupling between the work surface and the modular support member is non-permanent and made at a variable position on the support member. More preferably, the variable coupling is made using a locking pin assembly.

In an additional embodiment employing a modular support member, an armrest is coupled to the support member. Preferably, the coupling between the armrest and the modular support member is non-permanent and made at a variable position on the support member. More preferably, the variable positioning is made using a locking pin assembly.

In an embodiment employing an armrest, a tray is coupled to the armrest. Preferably, the coupling between the tray and the armrest is non-permanent.

In another embodiment, the seat may pivot on the seat base pivot pin to which it is coupled so as to present a declined, a substantially horizontal, or inclined position. In an embodiment, the chair can accommodate a user in a range of seating positions from reclined, to upright, to inclined.

In yet another embodiment, the chair base has a plurality of articulating support legs.

In an embodiment of the chair, the chair base is adapted for permanent or semi-permanent attachment to a floor.
