Nestable and stackable chair

Abstract

A chair is provided comprising a seat assembly including a seat back and a seat bottom and a support frame including a left leg assembly and right leg assembly connected by a transverse support member. The seat back is pivotably connected to each of the leg assemblies such that an upper portion of the seat back pivots in relation to the leg assemblies between a first seat back position and a second seat back position. The seat bottom is rotatable in relation to the seat back between an upright position and a horizontal position. The seat bottom is slidingly engaged with the leg assemblies such that pivoting of the seat backward from the first seat back position to the second seat back position causes the seat bottom to slide forward from a first seat bottom position to a second seat bottom position.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates generally to the field of seating and in particular to a reclining chair that is stackable and nestable. [0002] Chairs for extended seating applications, such as banquet halls and conference rooms, should preferably be comfortable, durable, and either stackable or nestable for storage purposes. Traditional stackable banquet chairs include a pair of inverted-U-shaped leg members attached to opposite sides of a generally horizontal seat. A generally L-shaped back support frame interconnects with the leg members and extends upwardly from the rear of the seat to support a back cushion. This type of chair may be stacked by placing the inverted-U-shaped leg members of one chair over the top of the leg members of another chair, such that the seat of the upper chair is supported just above the seat of the lower chair. Examples of traditional stackable banquet chairs are shown in U.S. Pat. No. 3,102,733 to Burnett and U.S. Desi...

AI Technical Summary

Benefits of technology

[0008] In order to address these needs, the present invention contemplates a chair comprising a seat assembly including a seat back and a seat bottom and a support frame including a left leg assembly and right leg assembly connected by a transverse support member, each of the leg assemblies including a seat back support member. The seat back is pivotably connected to each of the seat back support members such that an upper portion of the seat back pivots in relation to the seat back support members between a first seat back position and a second seat back position. The seat bottom is rotatably connected to a lower portion of the seat back such that the seat bottom is rotatable in relation to the seat back between an upright position and a horizontal position. The seat bottom is slidingly engaged with the seat back support members such that pivoting of the upper portion of the seat backward from the first seat back position to the second seat back position causes the lower portion of the seat back to pivot forward thereby causing the seat bottom to slide forward in relation to the seat back support members from a first seat bottom position to a second seat bottom position.

[0009] The configuration of the support frame and seat assembly allows the chair to be stacked with other chairs having a similar configuration when the seat bottom is in the horizontal position. Moreover, the same configuration allows the chair to be nested with other chairs having a similar configuration when the seat bottom is in the upright position.

[0010] The left and right leg assemblies may be comprised of a front leg member and a rear leg member connected in a criss-cross configuration. Lower portions of the front leg members and the rear / leg members may be continuously downwardly curved from the crossing point of the front leg member and the rear leg member such that the front leg member and the rear leg member exhibit an arched configuration in profile that provides a sturdy base for supporting and distributing the weight of a person sitting in the chair.

[0014] Accordingly, it is one object of the invention to provide an ergonomic chair that includes features that allow a user to easily recline the chair while the seat back maintains support for the user's back. Another object is achieved by features of the invention that allow the chair to not only recline, but also be easily stacked or nested when not in use.

Problems solved by technology

A problem is that these requirements create conflicting design criteria.

For example, low-cost chairs tend to be less comfortable and less stylized.

Chairs that are more comfortable, such as so-called “synchrotilt” chairs, have more expensive components and greater assembly costs, are neither stackable nor nestable for dense storage, and are usually too heavy to be lifted and / or stacked for storage.
