A synchrotilt chair includes a base, a back, a seat, and a pair of parallel links pivoted to a rear of the base and to a bottom of the back to form a four-bar linkage arrangement. A spring arrangement includes leaf springs that extend between each link and the base to bias the link and in turn the back and seat toward an upright position, with the back and seat pivoting with a synchronous motion upon recline of the back. The base, the back, the seat, and the links are shaped to receive identical chairs along a stacking direction to form a densely nested stacked arrangement for compact storage. The base has a distinctive horizontal U-shaped mid-frame structure defining a plurality of corners, and further having up legs and down legs extending upwardly and downwardly, respectively, from each of the corners, with the pair of links attached to the two rearmost ones of the up legs. The base (and also separately the back and the seat structures) are injection molded as single pieces from a reinforced polymeric material in a manner that provides a lightweight, yet surprisingly rigid and sturdy construction. Armrests are pivoted to the back and have a shape configured to allow nested stacking while also providing excellent comfort, durability, and style.

A stackable chair having a support structure and a seat and a back mounted to the support structure. The support structure includes two horizontally extending runner portions, each with two pairs of grooves. Mounted to the runner portions and engaged with the pairs of grooves are four glides. Each glide includes two arms and a base and a recess in the base. The arms each have a horizontally extending rib projecting inwardly so as to engage the grooves. Molded into each glide at the recess is a hard industrial felt member.

According to various embodiments of the present invention, a tablet arm for a nesting chair including a first rigid support member affixed to a nesting chair, a second rigid support member swivelably coupled to the first rigid support member, a tablet rotatably and slidably coupled to the second rigid support member by a collar, a first stop coupled with the second rigid support member and configured to abut one end of the collar in the tablet's forward operable position, and a second stop coupled with the second rigid support member and configured to abut another end of the collar in the tablet's rearward operable position. According to some embodiments, a plurality of nesting chairs having swiveling rotatable tablets movable from an operable position to a nested position, the tablets positioned over seatbacks of the chairs in the nested position and configured to slide horizontally in the operable position.

A molded chair shell includes a seat portion and a back portion joined at a junction area. A support or reinforcement member is located at the junction area and is formed integrally with the seat portion and the back portion. The reinforcement member includes an internal cavity between the seat portion and the back portion that is substantially positioned over the junction area. The cavity is formed by cavity walls, which may form ribs that extend forwardly along the seat portion and upwardly the back portion of the chair shell. The chair shell may be formed in an injection molding process, and the internal cavity may be formed in a gas assist operation carried out during the injection molding process.

A chair includes a seat and a seat frame including several legs. Bumpers are coupled to the legs and arranged to separate one chair from an underlying chair in a stack of chairs.

A chair includes a base that has a generally U-shaped member. The generally U-shaped member is comprised of a front member attached to a first end portion and a second end portion. A seat is supported on the base and is moveable from an upright position to a reclined position. A first resilient member is attached to the first end portion of the generally U-shaped member. A second resilient is attached to the second end portion of the generally U-shaped member. End portions of the first and second resilient members are attached to the seat adjacent to a rear portion of the seat. The first and second resilient members are sized and configured to resiliently move or flex such that the seat is positioned at the reclined position when a user sits on the seat.

A vertical stacking leg-over-leg ganged chair is attachable side-by-side and includes an upper frame adapted to receive and support a seating platform, and a lower frame supporting the upper frame, and a backrest for supporting a user seated in the chair. The ganged chair includes a front pair of legs angled frontward, and a rear pair of legs angled rearward, each pair connected underneath the lower frame. The right legs are connected to a right frame member, and the left legs to a left frame member, with the left frame member being of a lesser length than the right frame member. In a side-by-side ganged setup, the wider spaced apart right legs of one ganged chair fit over the left legs of a second like chair, forming a single width leg unit on either side of the ganged chairs. Each upper portion of the left legs includes an elongated slot that accepts an elongated lug on the upper portion of each right leg, for connective support when chairs are attached horizontally. The configuration of legs, the angles of the legs, and the rearward angle of the backrest, allow the ganged chair to be stacked vertically for ease of transfer. The leg-over-leg structure allows connection side-to-side, providing a lesser overall width of chairs when in the ganged configuration.

A stackable chair has supporting side members that comprise two bars that cross one another in non-contacting relation to form a substantially X-shaped configuration, the two bars capable of flexing movement relative to one another, so that the chair can flex in response to the weight and movement of the user.

A chair includes a tubular U-shaped back frame. The back frame defines a pair of spaced apart back legs. A pair of tubular L-shaped side members, each of which defines a front leg and an arm, are connected the back legs. A tubular U-shaped seat frame is connected to each of the front legs and each of the back legs. A connecting member is connected across the seat frame adjacent the connections of the seat frame to the back legs.

A stackable chair 1 includes a seating member 4 comprising a seat 2, and a plurality of chair legs 5. Each of said chair legs 5 is attached to the seating member 4 by means of its own connecting device 11. The connecting device 11 includes a connecting plate 9 which is inserted in a recess 10 of the seating member 4 such that it does not extend beyond the seating member 4 where the chair 1 is adjacent to other chairs in the stacked condition. The chair leg 5 is attached to the connecting plate 9. The result is a chair 1 which can be stacked in a compact manner.

A stackable chair having a back member may flex to allow for improved user comfort. An inline spring-to-frame configuration with a pair of spring members reinforced by steel plates on the top and bottom of each end of each spring is attached to the underside of the left and right members of the seat support frame. The spring-to-frame configuration may allow the back support frame to flex relative to the seat support frame.

A foldable chair includes a first leg, a second leg pivotally connected with the first leg, and a seat module pivotally mounted on the first leg and detachably locked on the second leg. The second leg is formed with a forward protruding holding portion formed with a downward facing locking recess. The seat module includes a support frame pivotally connected with the first leg and formed with an upward protruding catch portion rested on the holding portion and detachably locked in the locking recess, so that the seat module is combined with the second leg. Thus, the expanded foldable chair has a rigid and stable structure.
