A chair includes a lower chair and an upper chair. The lower chair includes a tilt-swivel mechanism defining a vertical swivel axis, a yoke, and a column extending between the tilt-swivel mechanism and the yoke. The upper chair is pivotably mounted to the yoke about a horizontal upper chair pivot axis. The upper chair includes a seat adapted to cradle the ischial tuberosities of a user.

An article of furniture including a bottom frame, a plurality of panels forming an outer surface of the article of furniture, and a plurality of struts for securing the panels in place. The bottom frame has an outer periphery which is securable to at least some of the panels. The bottom frame is configured for placement on a floor surface. Further, each strut has an elongated member configured for securement to at least two adjacent panels which are oriented in different planes from one another. The adjacent panels are secured to the respective struts with removable fasteners.

An adjustable support for differentially adjusting the height of a user's ischial tuberosity to relieve pain from sitting is disclosed. The support includes an adjustable left and right platform, each including at least one stackable lift having a stiffness sufficient to provide pressure to lift the sitz bone(s). Each lift is shaped and sized so that it can be securely stacked on top of the other. The stackable lifts may be connected along an inner edge in a hinged manner or can be received within at least one pouch and movable between the left and right platforms. To lift the height of the lower sitz bone the right and left platforms have a differential height between them, determined by the amount of adjustment needed. The differential adjustable seating height creates a counterbalancing repositioning of the sitz bones relieving the asymmetrical pressure of the sacral/lumbar complex caused by misalignment.

A seat has a supporting frame being rigid, two seat cushions disposed above the supporting frame, and two supporting members. The supporting frame has a main body and four side bodies fixedly mounted on two front ends and two rear ends of the main body. The supporting members are mounted on bottom surfaces of the seat cushions and are connected to the supporting frame. Each one of the supporting members has multiple supporting elements respectively located at a front half section and a rear half section of a corresponding one of the seat cushions. Each one of the supporting elements has a guiding rod mounted on the supporting frame and a main spring disposed around the guiding rod. The seat provides good support by the supporting frame and the supporting members and provides a cushioning performance by the main spring.

A seat for vehicles includes: a seat back frame; and a pressure receiving member that is mounted on the seat back frame to support a back of an occupant. The seat back frame includes a lower seat back frame and an upper seat back frame mounted on an upper portion of the lower seat back frame in a forwardly and rearwardly swingable manner, and the pressure receiving member is disposed from an area corresponding to the shoulder of an occupant to an area corresponding to the waist of the occupant and is supported by the upper seat back frame.

A chair back height adjustment mechanism comprises a guide having an abutment surface at a lateral side of the guide which extends along an adjustment direction. The chair back height adjustment mechanism comprises an adjusting device supported on the guide so as to be displaceable along the adjustment direction. The adjusting device comprises a carrier, a coupling member which is moveably supported on the carrier, and a bias mechanism. The coupling member has a contact face shaped to abut on the abutment surface of the guide and a slanted face. The bias mechanism is operative to apply a force onto the slanted face to urge the contact face of the coupling member against the abutment surface of the guide.

A pelvic tilt detecting chair is provided to a user to sit and configured to detect a pelvic angle of the pelvis of the user in sitting position. The pelvic tilt detecting chair comprises a base, a supporting component, a carrying component and a detector. The base has a horizontal surface. The supporting component comprises a first end connected to the base and a second end. The carrying component is moveably configured and comprises an installing surface coupled to the second end and a chair surface configured to contact the pelvis of the user. The chair surface and the horizontal surface form a tilt angle when the user sits on the carrying component. The detector stores a tilt angle threshold value and is configured to the carrying component to detect the tilt angle. The detector generates a warning signal when the tilt angle is not matched up with the tilt angle threshold value.

An intelligent automated chair that is configured to have uploaded various operating models to run a sequence of patterns that cause the intelligent automated chair to alternate between various positions. An intelligent automated chair system configured to receive data from various inputs including user input, sensors, biosensors, historical usage, profile, and others to generate a recommended operating model for the intelligent automated chair. An intelligent automated chair system running an operating model that is interruptible manually by a user or as a result of sensed date, which can alter the pattern or parameters of the operating model.

The present invention relates to support apparatus for supporting at least a portion of a gluteal region of a user while the user is seated in a seating apparatus comprising a seating surface, a back support surface and a transition region at the intersection of the seating surface and the back support surface. The support apparatus a support member structured to support at least a portion of the gluteal region of the user. The support apparatus further comprises a support element structured to position the support member at the transition region of seating apparatus such that the support member extends between the seating surface and the back support surface of the seating apparatus.

The invention relates to a chair for accommodating a person. The chair includes an upper body section having an upper body contact surface adapted or adaptable to at least parts of a front of a torso or a rear of a torso of a person placed on the chair, and a lower body section having a lower body contact surface adapted or adaptable to at least parts of at least a front of a thigh of the person, wherein the upper body section and the lower body section are arranged or arrangeable and fixable in a position relative to each other such that the upper body contact surface and the lower body contact surface cause a hyperextension posture of the hip joint of the person with a predetermined hyperextension angle. By forming the hyperextension angle of the hip on the chair, shortening of the anterior thigh and hip muscles can be counteracted. Also disclosed are a pressing device for application to the human body, which is adapted for use on a chair and which includes one or more pressure units each having at least one pressure head adapted to apply local or point pressure at a predetermined pressure location on the body of a person accommodated on the chair, and a chair having such a pressing device.
