摘要:
A rocker chair having a frame and a longitudinal spring member extending from the frame, at or near a surface on which the chair is supported for rocking motion. The spring member includes an anchored portion anchored to the frame, and an extended portion extending from the anchored portion and is free to flex or bend against spring bias of the extended portion, wherein the extended portion is bendable upward from the support surface against spring bias of the extended portion. The frame of the rocker chair may be collapsible to convert from a collapsed configuration for stowing, to an extended configuration for seating a person. The spring member may include an anchored portion anchored to at least a portion of a bottom of the frame, and an extended portion extending from the anchored portion, wherein the extended portion is bendable against spring bias of the extended portion.

A chair that can transition from an upright position to a reclined position includes a base to rest on a floor, a post upstanding from the base, a chassis affixed to a top of the post and having left and right extensions, armrests extending upward from the left and right extensions. A seat is made up of a seat pan and a seat upper support frame, which are positioned under and above the chassis respectively and has a hole through which the post extends. A backrest has a lower end pivotally joined to the seat and a pivotal connection to each of the armrests, so rearward pressure on an upper area of the backrest causes pivoting of the backrest at the armrests and at the seat, pushing the seat forward to a reclined position in a synchronous motion.

A portable lumbar support and ergonomic chair having a lumbar support. The lumbar support has a seat hingedly coupled to a seat back having a teardrop-shaped lumbar support seat back cushion. A rigid back support portion may be rotated forward about hinges to collapse substantially parallel to the seat frame and backward to open to a variety of angles with respect to the seat frame. The seat back freely pivots around an upper lateral axis, and the rigid back support portion is linearly adjustable to space the seat back toward and away from the hinges to enable raising or lowering the upper lateral axis and thus the seat back with respect to the lower lateral axis. This provides multiple ways of changing which part of the teardrop-shaped lumbar support curve hits your lumbar curve for proper support. Variable lumbar lordotic support is thus provided.

A spring actuated rocking mechanism can be attached to the legs of a collapsible chair to allow for the user to rock in the collapsible chair. The mechanism may be attached at the factory or retrofitted to the chair. The rocking mechanism can be attached to the end of a leg or disposed within a leg, having a leg portion above and below the mechanism.

A flexible chair having a seat bottom supported by a seat frame, a seat back having a lower portion thereof rotatably attached to the seat frame, and a back frame rotatably attached to an upper portion of the seat back. The back frame includes a pair of lower ends that are each slidably engaged with the seat frame or the seat bottom. A support post is attached to and supports the back frame. A pair of springs apply a bias force between the lower ends and the seat frame or the seat bottom. As a user sits on the seat bottom and leans back against the seat back, the seat back pivots and the seat bottom slides forward. Alternately, a link member can be used between the seat bottom or seat frame, and the post, to lift the seat bottom as it moves forward.

A high density stacking flex chair is disclosed. A frame has a seat attached thereto, and a back pivotally attached thereto. The back is curved and can tilt backwards, but is limited by the frame which, through the back, has a lesser radius of curvature and is angled downward, thus providing stop action for back rotation.

A chair has two lateral frame parts, each one in the form of a single, continuous member of an elastically yielding material. Transverse rods are connected between the lateral frame parts. A seat is connected to at least one of the transverse rods and a back rest is connected to at least one of the transverse rods. The single member of the lateral frame parts is preferably made of spring steel. Connecting elements that are slipped onto the lateral frame parts are used for connecting the transverse rods to the lateral frame parts. The connecting parts can be balls having throughbores for receiving the lateral frame parts and threaded holes, extending substantially perpendicularly to the throughbores, for receiving the transverse rods.

A chair or the like with an undercarriage, having a seat surface that is attached in a resilient manner to the undercarriage and a backrest that is connected in a resilient manner to the seat surface, wherein to assure a flexible and individual conformity of the chair or the like to the body placing a load on it. A plurality of flexible strips are disposed next to one another and attached in their end area in a nearly horizontal orientation to the undercarriage which act as a seat surface, and wherein a plurality of strips disposed next to each other in a nearly perpendicular orientation act as a backrest and are connected with their one end area to a strip and with their other end to the seat surface.
