An ergonomically improved chair in which the user's thoracic region is supported by a narrow and generally flat or moderately convex thoracic cushion in the midrest region of the chairback. The design omits or greatly minimizes support for the user's scapulae and other areas of the back outside the thoracic region, excepting lumbar and cervical support features in some embodiments. The design differs from the prior art at least in that the thoracic cushion is narrow and configured not to complement that user's spinal curvature. By appropriate selection and design, a chair incorporating the invention may comprise a fabric covering portions of the chairback without significantly affecting functionality. Other embodiments include a chairback comprising regions having differing levels of firmness and/or differing cushion height at appropriate regions to promote concentrated support of the user's thoracic region.

A vehicle seating assembly including a lower seatback. An upper seatback is operably coupled to the lower seatback. The upper seatback is pivotally mounted to the lower seatback at a pivot axis. An arcuate back support bar is disposed in the upper seatback and is configured to rotate the upper seatback between forward and rearward positions. The arcuate support bar includes first and second generally linear members and an arcuate intermediate portion disposed between the first and second generally linear members. An articulation assembly operably couples the lower seatback with the upper seatback.

An apparatus for sitting, including: a keystone assembly which connects various parts of the apparatus; a back that provides support for at least a person's back or shoulders; a floating lumbar support, which provides support for a person's lower back, attached to the keystone assembly; a seat that can adjust between a forward tilted and reclined position; a plurality of rollers, disposed on the keystone assembly, on which the seat rests; a central column, attached to the keystone assembly, on which the seat can spin; and a lower torsion spring connected to the seat and disposed on the keystone assembly allowing controlled movement of the seat.

A flexible backrest for a folding chair includes a flexible backrest panel which can assume a curved configuration of use and an extended storage configuration. The flexible backrest panel has a support surface having a concave shape in a cross-section in a horizontal plane, and a convex shape in a cross-section in a vertical plane; and the flexible backrest panel has a plurality of vertical through-slits forming a plurality of vertical slats.

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.

A locker includes a pair of spaced-apart upstanding sidewalls and at least one shelf extending between the sidewalls, the shelf and sidewalls defining a compartment. A tray is carried on the shelf in the compartment and supported by a pair of rollers and coupled to a pair of rails mounted on the sidewalls above the shelf, wherein the tray slides forward and backward relative to the shelf and rotates about the rollers.

A chair is described herein. The chair includes a first back support coupled to a base of the chair using one or more first support arms. The chair also includes a second back support coupled to the base of the chair using one or more second support arms. The first and second back supports are independently rotatable about a common axis.

To provide a user with a new sensation through a tactile sensation, an auditory sensation, and a visual sensation, a human body support device has an overall shape that can easily be used as a chair or a couch. The human body support device includes a frame that is formed from, for example, metal or resin, and a plurality of modules that are arranged in a plurality of sites to support the user body on the frame. These modules include a sound emitting module that is provided with a speaker, and a vibrating and light-emitting module that is provided with an LED and a voice coil motor. These modules have an elastic part that is formed by an elastic material such as a sponge in a location that is in contact with the user body. The orientation and position of the modules are designed so as to be in proper contact with and support the user body, and accordingly, the user body can be comfortably supported.
